Speech therapy in food transition from probe to breast in newborn in kangaroo method

Abstracts

Purpose

: Verify the relationship between gestational age and duration of speech therapy to start oral feeding, when used the technique of feeding transition of the probe directly to the chest.

Methods

: This is a study of newborn medical/speech records of 38 risk in Kangaroo unit.

Were collected

: gestational age at birth and corrected days of life, birth weight and current, type and duration of speech therapy, enteral feeding volume. We used time use of antibiotics and ventilatory support as criteria for division of newborns into two groups (G1 and G2). At the statistical analysis was applied the nonparametric test of Mann-Whitney and the Pearson’s correlation coefficient.

Results

: Intervention time for newborns were discharged speech showed no significant results between groups (G1 = 9.35 days and G2 = 10.12 days), although the initial hypothesis of this study was that the newborn G1 would require fewer days of speech therapy than the G2. There was statistically significant difference in birth weight between G1 (1563.53 g) and G2 (1409.62 g).

Conclusion

: It was observed that both groups started speech therapy and oral feeding practically medium of similar gestational ages and both speech intervention, demonstrating ability to coordinate sucking movements/breathing/swallowing, and consequently the effective and exclusive breastfeeding.

Objetivo

: Verificar a relação entre idade gestacional e tempo de intervenção fonoaudiológica para início da alimentação via oral, quando utilizada a técnica de transição alimentar da sonda direta para o peito.

Métodos

: Trata-se de um estudo do prontuário médico/fonoaudiológico de 38 recém-nascidos de risco em Unidade Canguru. Foram coletados os seguintes dados: idade gestacional ao nascimento e corrigida, dias de vida, peso ao nascimento e atual, tipo e duração da intervenção fonoaudiológica, volume de dieta por sonda. Utilizou-se o tempo de uso de antibióticos e o suporte ventilatório como critérios de divisão dos recém-nascidos em dois grupos (G1 e G2). Na análise estatística, aplicou-se o teste não paramétrico de Mann-Whitney e o coeficiente de correlação de Pearson.

Resultados

: O tempo de intervenção para os recém-nascidos que receberem alta fonoaudiológica não apresentou resultados significativos entre os grupos (G1= 9,35 dias e G2= 10,12 dias), embora a hipótese inicial deste estudo fosse a de que os recém-nascidos do G1 necessitariam de menor período de atendimento fonoaudiológico que os do G2. Houve diferença estatisticamente significativa para o peso ao nascimento, entre G1 (1563,53 g) e G2 (1409,62 g).

Conclusão

: Quando utilizada a técnica de transição alimentar da sonda direta para o peito, em recém-nascidos de risco com média de idade gestacional semelhante e mesmo tempo de intervenção fonoaudiológica, os bebês demonstraram aptidão para coordenar os movimentos de sucção/respiração/deglutição, e consequentemente, a amamentação efetiva em seio materno exclusivo.

INTRODUCTION

Breastfeeding brings many benefits, both for the baby and for the mother ( 1Rocha MS, Delgado SE. Intervenção fonoaudiológica em recém-nascido pré-termo com Gastrosquise. Rev Soc Bras Fonoaudiol. 2007;12(1):55-62. ) . Specifically regarding to speech therapy ( 2Varandas CPM, Campos LG, Motta AR. Adesão ao tratamento fonoaudiológico segundo a visão de ortodontistas e odontopediatras. Rev Soc Bras Fonoaudiol. 2008;13(3):233-9. ) breastfeeding provides the proper development of the stomatogmathic functions of the newborn (NB), since, while sucking breast, can establish adequate orofacial musclesstimulus ( 2Varandas CPM, Campos LG, Motta AR. Adesão ao tratamento fonoaudiológico segundo a visão de ortodontistas e odontopediatras. Rev Soc Bras Fonoaudiol. 2008;13(3):233-9. , 3Pivante CM, Medeiros AMC. Intervenções fonoaudiológicas no aleitamento materno junto às mães de paridade zero. Mundo Saúde. 2006;30(1):87-95. ) .

The development of strategies to promote breastfeeding is extremely important, both to ensure the survival of the human species, favoring immunity, digestion and nutrients absorption ( 4Fujinaga CI, Scochi CGS, Santos CB, Zamberlan NE, Leite AM. Validação do conteúdo de um instrumento para avaliação da prontidão do prematuro para início da alimentação oral. Rev Bras Saúde Matern Infant. 2008;8(4):391-9. ) , and by the fact that breastfeeding be considered in many cultural and social contexts, as an act of love. Authors ( 5Delgado SE, Halpern R. Amamentação de prematuros com menos de 1500 gramas: funcionamento motor-oral e apego. Pró-Fono R Atual Cient. 2005;17(2):141-52. ) state that the act of breastfeeding promotes greater interaction between mother-infant for bonding expanding purposes.

The birth of a baby in risk (low weight and/or premature) can cause numerous difficulties in adaption to extrauterine life, given the immaturity of respiratory, circulatory and gastrointestinal functions. Before the 60´s, it was rare the premature newborns (PN) in very low birth weight (VLBW) to survive. However, with technological advances and the medicine resources, the survival of this population has increased considerably ( 5Delgado SE, Halpern R. Amamentação de prematuros com menos de 1500 gramas: funcionamento motor-oral e apego. Pró-Fono R Atual Cient. 2005;17(2):141-52.

About risk criterions, the Ministry of Health ( 8Brasil, Ministério da Saúde, Secretaria de Vigilância em Saúde/Secretaria de Atenção à Saúde. Manual de vigilância do óbito infantil e fetal e do comitê de prevenção do óbito infantil e fetal. 2 a. ed. Brasília: Ministério da Saúde; 2009. (Série A. Normas e manuais técnicos). ) , ranks as underweight newborns on less than 2500 g, and very low birth weight, those born with weight less than 1500 g and as extremely low birth weight newborns with weight less than 1000 g. Regarding to prematurity, the literature ( 9WHO - World Health Organization. International statistical classification of disease and related health problems: 10 th revision. Geneva: World Health Organization; 2010 [acesso em: jun 2013]. Disponível em: http://apps.who.int/classifications/icd10/browse/2010/en#/P07.2
http://apps.who.int/classifications/icd1...
) considers the term all newborn infants with gestational age (GA) between 37 and 41 weeks, as preterm, cases where the baby is born into less than 37 completed weeks ( 1010 Martins Filho J. Neonatologia: prioridade. In: Figueira F, Ferreira OS, Alves JGB. ediatria: Instituto Materno-Infantil de Pernambuco. 2 a. ed. Rio de Janeiro: Medsi; 1996. p. 139-44. ) ; as post-term, with GA higher or the same as 42 weeks ( 9WHO - World Health Organization. International statistical classification of disease and related health problems: 10 th revision. Geneva: World Health Organization; 2010 [acesso em: jun 2013]. Disponível em: http://apps.who.int/classifications/icd10/browse/2010/en#/P07.2
http://apps.who.int/classifications/icd1...
) , as limitrophes when his/her GA is between 35 and 37 weeks, and moderate with GA 31 and 34 weeks and as extreme, between 24 and 30 weeks ( 1111 Sousa MWCR, Silva WCR, Araújo SAN. Quantificação das manipulações em recém-nascidos pré-termo em Unidade de Terapia Intensiva: uma proposta de elaboração de protocolo. Conscientia e Saúde. 2008;7(2):269-74. ) .

The ninth week of pregnancy until birth (fetal growth period) ( 1212 Almeida MNF, Siqueira TO, Ribeiro SMM.

Contato das mãos com a região oral, protrusão de língua e movimentos de sucção em recém-nascidos humanos, a partir da estimulação oro gustativa [tese]. São Paulo: Instituto de Psicologia, Universidade de São Paulo; 2002. ) , several behaviors are being developed. Swallowing movements are initiated approximately at 11th week and then oral reflexes and lip movements. The beginning of suction occurs between the 17th and 24th week, however, no coordination between these functions. It is approximately between 25th and 27th week happens the respiratory movements ( 1313 Medeiros AMC. Contato das mãos com a região oral, protrusão de língua e movimentos de sucção em recém-nascidos humanos, a partir da estimulação oro gustativa [tese].

- 1717 Mizuno K, Ueda A. The maturation and coordination of sucking, swallowing, and respiration in preterm infants. J Pediatr. 2003;142(1):36-40. ) indicate that only in the 34th or 35th week, the suction will be globally coordinated with swallowing and breathing. However, some studies ( 1818 Bühler KEB, Limongi SCO. Fatores associados à transição da alimentação via oral em recém-nascidos pré-termo. Pró-Fono R Atual Cient. 2004;16(3):301-10. , 1919 Medeiros AMC, Oliveira ARM, Fernandes AM, Guardachoni GAS, Aquino JPSP, Rubinick ML, et al. Caracterização da técnica de transição da alimentação por sonda enteral para seio materno em recém-nascidos prematuros. J Soc Bras Fonoaudiol. 2011;23(1):57-65. ) suggest that clinically stable preterm infants with feeding readiness, oral stimulation can start “training suction” with accompanying speech pathologist and oral feed via earlier.

Difficulties in establishing the right time to start breastfeeding can happen among health professionals and there have been times where only the gestational age and weight were used as indicators for early oral feeding. However, the readiness and success of oral feeding depends on, not only on the gestational age and weight, but other variables such as physiological and clinical stability, muscle tone, pertaining to weight gain, prior sucking experience, oral motor skills, presence of searching reflexes during skin to skin contact, coordination between sucking, swallowing and breathing functions (S/S/B), behavioral organization of the baby, the environment control and posture and coordination to ingest the prescribed diet volume ( 4Fujinaga CI, Scochi CGS, Santos CB, Zamberlan NE, Leite AM.

In Brazil, the perinatal conditions that, in the beginning, contribute to neonatal and perinatal mortality and morbity, are very common problems in PTNBs and low birth weight ( 2222 Brasil, Ministério da Saúde, Secretaria de Atenção à Saúde. Atenção humanizada ao recém-nascido de baixo peso - Método Canguru: 2 a. ed. Brasília: Ministério da Saúde; 2011. (Série A. Normas e manuais técnicos, 145). ) . Given the immaturity and the difficulties presented by the PTNBs, it is necessary to ensure a differentiated monitoring about the survival and quality of life of NB in risk.

Regarding to feeding, even if the offer of diet is done orally via (OV), especially breastfeeding, it is ideal and desired ( 1Rocha MS, Delgado SE. Intervenção fonoaudiológica em recém-nascido pré-termo com Gastrosquise. Rev Soc Bras Fonoaudiol. 2007;12(1):55-62. ) to be done by alternative ways such as gastric tubes, is, in some cases, the only way to ensure survival of preterm infants ( 1Rocha MS, Delgado SE. Intervenção fonoaudiológica em recém-nascido pré-termo com Gastrosquise. Rev Soc Bras Fonoaudiol. 2007;12(1):55-62. , 2222 Brasil, Ministério da Saúde, Secretaria de Atenção à Saúde. Atenção humanizada ao recém-nascido de baixo peso - Método Canguru: 2 a. ed. Brasília: Ministério da Saúde; 2011. (Série A. Normas e manuais técnicos, 145). ) , although prolonged use is considered by some authors ( 1919 Medeiros AMC, Oliveira ARM, Fernandes AM, Guardachoni GAS, Aquino JPSP, Rubinick ML, et al. Caracterização da técnica de transição da alimentação por sonda enteral para seio materno em recém-nascidos prematuros. J Soc Bras Fonoaudiol. 2011;23(1):57-65.

In responsive disposition to low birth weight in” New Born Humanized Care Precept” from the Health Ministry ( 2222 Brasil, Ministério da Saúde, Secretaria de Atenção à Saúde. Atenção humanizada ao recém-nascido de baixo peso - Método Canguru: 2 a. ed. Brasília: Ministério da Saúde; 2011. (Série A. Normas e manuais técnicos, 145). ) and according to Decree nº 930 of May 10, 2012, the speech therapist is professionally trained ( 2424 Barros APB, Querija DS, Marinho MCCR. Caracterização do atendimento fonoaudiológico em pacientes internados. Rev Méd Ana Costa. 2007;12(2):34-7. ) and must be inserted into neonatal units and the Kangaroo method, integrated into the interdisciplinary team.

The can work in promoting the practice of early breastfeeding, promoting and stimulate, oral feeding, assist in the transition from using the probe to the breast, helping to improve the quality of the NB’s life, since such actions may decrease hospital stay, allowing earlier discharge ( 2424 Barros APB, Querija DS, Marinho MCCR. Caracterização do atendimento fonoaudiológico em pacientes internados. Rev Méd Ana Costa. 2007;12(2):34-7. ) .

The Kangaroo method is a neonatal care focused on the care of premature newborns, which consists on placing the baby in skin to skin contact with the mother´s ( 2222 Brasil, Ministério da Saúde, Secretaria de Atenção à Saúde. Atenção humanizada ao recém-nascido de baixo peso - Método Canguru: 2 a. ed. Brasília: Ministério da Saúde; 2011. (Série A. Normas e manuais técnicos, 145). ) . The method´s idea is the placement of the NB by the mother´s breast being this contact the one who will provide greater thermal stability, and replace incubators, allowing early discharge, decrease the rate of nosocomial infection and, consequently, improve the quality of care with less cost to the health system.

The method is developed in three steps ( 2222 Brasil, Ministério da Saúde, Secretaria de Atenção à Saúde. Atenção humanizada ao recém-nascido de baixo peso - Método Canguru: 2 a. ed. Brasília: Ministério da Saúde; 2011. (Série A. Normas e manuais técnicos, 145). ) : the first begins at prenatal, by indentifying pregnant women in risk of giving birth to underweight child. In this situation, the mother receives specific guidance on the precautions to be taken with her and the baby after birth, in case if there is need for keeping the NB in Neonatal Intensive Care (NICU). During this period, it is important that the stimulus from the mother to lactation (hand milking) is started. On the second step, the infant is clinically stable and weighing the same or higher than 1250 g. It is necessary that the mother be orientated and feel safe to handle the NB, showing availability and interest to stay with her child in rooming, where the kangaroo position will be held. In this step, breastfeeding will be stimulated and the interdisciplinary team shall observe and support all necessary procedures for the project´s success. Finally, third step happens after discharge, representing the phase of ambulatory treatment for attention to the growth and development of the NB, family – infant interaction and early detection of risk situations. It is presumed that the third step can only happens if the child is with the minimum weight of 1600 g, clinically stable and gaining weight, preferably on exclusive breastfeeding.

In this context, the speech therapist can contribute to the monitoring and effectiveness of the transition from the gastric probe straight to breast technique (probe-breast). Sucking stimulation in (“empty breast”), concurrent to the provision of probe feeding is seen as the non-nutritive sucking technique (NNS), offering less risk to the infant, preventing him/her from chocking, while he/she doesn´t have S/R/D coordination. From the moment in while the RN acquires such coordination, he/she takes the swallowing training and it is performed in “breast partially filled”, simultaneously to the diet supplied by the probe. When is observed the effectiveness of weight gain, the amount of complement is decreased, until the infant is fed exclusively breastfed ( 2222 Brasil, Ministério da Saúde, Secretaria de Atenção à Saúde. Atenção humanizada ao recém-nascido de baixo peso - Método Canguru: 2 a. ed. Brasília: Ministério da Saúde; 2011. (Série A. Normas e manuais técnicos, 145). ) .

The aim of this study was to verify the corrected gestational age and kangaroo technique phases, as well as the time needed by the speech therapist for the diet feeding by exclusive oral vial and speech discharge, once this technique favors early breastfeeding and, thus, promotes discharge. As a specific aim, we tried to observe these aspects into the moment of oral feeding (“partially filled breast”) and the exclusive breastfeeding offer.

METHODS

The study was accomplished through approval by the Human Research Ethics Committee from Universidade Federal de Sergipe (UFS), under the nº PCEA – 02304812.0.0000.0058. All the newborn´s keepers were notified about the research and signed the Consent Form.

This is an observational and descriptive study, was conducted by using collected data from medical and speech therapy records from 38 newborns of both genders admitted to Neonatal Intermediate Care Unit Kangaroo (NICUKA), in a public maternity in Aracaju (SE), from August 2012 to April 2013.

The subjects of this study were divided two groups, according to this Chart 1.

Chart 1
Criteria for division of newborns in groups 1 and 2

As important medical complications, were considered cases of neuropathy, heart disease and/or severe respiratory disease, congenital abnormalities, and sepsis syndromes and cases that required increased length of stay in the neonatal intensive care unit, preventing the transfer of newborns in the kangaroo unit and early language intervention.

We opted for the division into groups according to the presence or absence of major medical complications from the assumption that this variable could affect the results, in relation to the type and length of speech therapy performed on newborns.

Term birth, post – term and those whose parents did not consent to their participation in research, the newborns who had at least one of the previous characteristics were excluded from the study.

From the consent of the parent or guardian, the study of medical and speech records of newborns, with some data gathering (Chart 2), recorded in a specific protocol (Appendix 1).

Appendix 1
Data collection on how to offer diet in the transition from gastric tube feeding for breastfed newborns in the Kangaroo Care Protocol

In the period preceding the assignment/release of supply from the breast, all newborns included in this study had to mandatorily have made use of exclusive probe feeding, with no prior experience with oral feeding. The onset of non-nutritive stimulation was given only after medical release, clinical stability verified, since the weight did not contraindicated speech stimulation in that kangaroo unit. The technique of direct transition from probe to breast (probe-breast) is described below (Chart 3).

Chart 3
Descriptive framework of standard speech therapy offered to study participants

Note that the steps described in Chart 3 were carried out gradually and successively, according to the feeding schedule established by the physician/hospital routine. This occurred, in most cases, every three hours. As the team of speech therapists did not remain in full-time, there was support from the nursing staff for implementing the steps. The second step was essential for the NB, breast suction training, at the same time that the diet was offered through the probe, providing a feeling of satiety while sucking, while not being able to coordinate S/S/B functions orally. We considered the presence of S/S/B functions when observed the balance between feeding efficiency and sucking, swallowing and breathing functions, without signs of stress (coughing, choking, fatigue, heart rate oscillation and 0 2 saturation). As the NB had adequacy of orofacial structures and conditions to coordinate S/S/B, the breast was emptied only partially, and diet was administered by probe at a lower volume, after sucking training on breast.

Later (third step), with the improvement of the conditions of swallowing from these NBs, “full breastfeeding” (mother´s breast without milking) was released, upon addition of probe, if still needed, been volume gradually lowered, as medical prescription, ponderal daily weight gain and newborns nutritional needs. When the probe complement was not needed, the diet was offered through breast, the free demand (MBFD), exclusive mode (fourth step), enabling speech therapy discharge.

In statistical analysis, the nonparametric Mann-Whitney test was used to compare the groups G1 and G2. This test is indicated when one wants to compare different data sets with medical measurement, independent samples and do not want to take guesses about the distribution of the samples ( 2525 Siegel S, Castellan Junior N. Estatística não-paramétrica para ciências do comportamento. 2 a. ed. Porto Alegre: Artmed/Bookman; 2006. ) .

The Pearson correlation coefficient (c) ( 2525 Siegel S, Castellan Junior N. Estatística não-paramétrica para ciências do comportamento. 2 a. ed. Porto Alegre: Artmed/Bookman; 2006. ) to the following intersections was also used: birth weight with days of life, during the speech assessment, birth weight with weight during assessment, gestational age at birth with corrected gestational age during the speech assessment. Data were considered at 0.05 or 0.01, been used, in this study, the following ranking correlation:

If | c | < 0,40 – weak correlation

If 0,40 < | c | < 0,70 – moderate correlation

If 0,70 < | c | < 0,90 – good correlation

If | c | > 0,90 – great correlation

RESULTS

During the period of data collection in Kangaroo Unit were assisted 96 underweight PNB, from which only 38, of both genders, met the inclusion criteria described above, and 17 of them were the G1 and 21, the G2.

The GAB average from G1 was higher than that found in G2.The WASS showed similar averages in both groups. At the assessment´s time, the NBs from G1 had corrected gestational age (CGAWASS) with a lower average than that from G2´s NBs. On the transition the offer of probe feeding to exclusively breastfed (probe-breast), in each of the steps, the training of non-nutritive sucking in “gloved finger” or “empty breast” (NNS GF/EB) was carried out for a longer period average period in G1 than in G2 (Table 1).

Table 1
Data on gestational age at birth, weight at the time the evaluation, corrected gestational age of the newborn in during the evaluation. Training time of nonnutritive stimulation gloved finger or empty breast

The offer of “partially filled breast”, which corresponds to the onset of supply given by oral via, was initiated by G1 averaging CGAOV lower than G2. Finally, on the step related to the offer from the breast without using the add-on probe, where OV diet was made exclusively from breast, G2 started averaging CGAMBE higher than G1 and the average time (in days) of the newborns subjected to the probe was higher in G2 than in G1, and G2 newborns remained in speech therapy (SPEECT) more days than G1 (Table 2).

At the moment of speech therapy discharge, G2 newborns showed CGAA higher than the G1s. The NBs were generally higher than that of G2. The G2 NBs presented, during the speech therapy, the average life-spawn (LSSTA) higher than the G1 (Table 3).

Table 3
Data corrected gestational age at discharge speech, weight of the newborn at birth and days of life during the evaluation

The Pearson correlation coefficient was used to correlate the BW with LSSTA, showing a reverse direction correlation between moderate to good. This result means that as higher the birth weight, lower life-spawn spent during the therapy. At the intersection between the GAB CGASTA was obtained from weak to moderate correlation in forward direction, meaning, the higher the gestational age at birth, the greater the corrected gestational age at the time of the speech evaluation. Importantly, all correlations were significant. Data on the Pearson correlation coefficient are shown on Table 4.

DISCUSSION

During the monitoring process technique in newborns, certain aspects restricted the recording of some data in the study protocol. One was the fact that, sometimes on the NBs prompts does not showed the gloved finger stimulation recording because the audiologist had not been the first professional to perform the procedure. In such cases, the beginning of NNS was made by empty breast. This made impossible to compare the techniques (gloved finger and empty breast) in this study. Another limiting aspect was the shortage of highly relevant recent literature, which addressed the feeding transition from probe straight to breast technique, with speech therapy intervention within the kangaroo unit.

In the present study, considering gestational age at birth (GAB), there was not any significant difference, when comparing G1 and G2, it is not possible to establish a direct relationship between the classifying of prematurity and the incidence of major complications (neuropathy, heart disease and/or severe respiratory disease, congenital abnormalities, and sepsis syndromes) in this population. There was the expectation that the group 1 would present gestational age higher than the group 2, since the literature states that the higher the GAB, less complications ( 2626 Chalfun G, Mello RR, Dutra MVP, Andreozzi VL, Silva KS. Fatores associados à morbidade respiratória entre 12 e 36 meses de vida de crianças nascidas de muito baixo peso oriundas de uma UTI neonatal pública. Cad Saúde Pública. 2009;25(6):1399-408. ) , that being so premature birth can cause major problems such as breathing diseases, but it did not.

According to the populations characterization, about the gestational age at birth, it was observed that newborns studied were not that premature, since the criteria to inclusion into the Kangaroo Care Program concerns the underweight and not necessarily the prematurity.

The fact that the group 2 had 2 babies who required longer hospitalization to start speech therapy, being higher than the average from group 1, can be related to complications such as infections, respiratory distress syndrome, neonatal anoxia, hemorrhage, periintravencular, necrotina enterocolitis, as the lower birth weight average ( 2727 Malveira SS, Moraes AN, Chermont AG, Costa DLF, Silva TF. Recém-nascidos de muito baixo peso em um hospital de referência. Rev Para Med. 2006;20(1):41-6. ) , whereas infants from group 2, who were born with significantly lower weight, had his/her prolonged stay, until reaching proper weight, to be transferred to Kangaroo Unit to try feeding stimulation.

Also in relation to weight, the fact that was obtained moderate to good reverse direction correlation, meaning the higher the birth weight, fewer days of life spent at the moment of speech evaluation, can be considered an important fact because despite the studied newborns be classified as very low birth weight, it was possible to start early speech therapy ( 2222 Brasil, Ministério da Saúde, Secretaria de Atenção à Saúde. Atenção humanizada ao recém-nascido de baixo peso - Método Canguru: 2 a. ed. Brasília: Ministério da Saúde; 2011. (Série A. Normas e manuais técnicos, 145). ) . According to the Health Ministry ( 2222 Brasil, Ministério da Saúde, Secretaria de Atenção à Saúde. Atenção humanizada ao recém-nascido de baixo peso - Método Canguru: 2 a. ed. Brasília: Ministério da Saúde; 2011. (Série A. Normas e manuais técnicos, 145). ) , to a NB go to the second step of Kangaroo Method, he/she must be with minimum weight of 1250 grams, which was observed in this population.

The fact that the babies were born with significant weight difference between the groups, but they presented similar weight and corrected gestational age at the time of assessment, may be related to the circumstances than the clinical conditions and the weight itself (to belong o group 1 and 2), were not directly linked to the initiation of speech therapy, although were considered important criteria for the entry of these babies in Kangaroo Unit in the maternity in question, which would start monitoring the probe-breast transition technique and speech therapy intervention.

Regarding weight, the literature ( 2828 Caetano LC, Fujinaga CI, Scochi CGS. Sucção não nutritiva em bebês prematuros: estudo bibliográfico. Rev Latino-Am Enfermagem. 2003;11(2):232-6. , 2929 Neiva FCB, Leone CR. Efeitos da sucção não-nutritiva na idade de início da alimentação via oral em recém-nascidos pré-termo. Rev Paul Pediatria. 2007;25(2):129-34. ) , indicates an averaging ranging between 1400 to 1800 grams, to start NNS stimulation, being the NB clinically stable, which agrees with what was found in this study, since the maternity follows the Health Ministry guidelines ( 2222 Brasil, Ministério da Saúde, Secretaria de Atenção à Saúde. Atenção humanizada ao recém-nascido de baixo peso - Método Canguru: 2 a. ed. Brasília: Ministério da Saúde; 2011. (Série A. Normas e manuais técnicos, 145). ) and the NBs only go to kangaroo unit when they reach the minimum weight of 1250 grams and clinical stability.

This study found that the weight gains is relevant for monitoring the transition technique in newborns in risk, it is important that the speech therapist is aware of the medical and nutritional requirements on the energy needs of this population, since most of healthy preterm infants usually gain weight appropriately, when he/she receives 120 cal/kg/day ( 2222 Brasil, Ministério da Saúde, Secretaria de Atenção à Saúde. Atenção humanizada ao recém-nascido de baixo peso - Método Canguru: 2 a. ed. Brasília: Ministério da Saúde; 2011. (Série A. Normas e manuais técnicos, 145). ) , as long as they are not subjected to excessive energy expenditure during stimulation.

Regarding to gestational age, several authors ( 2828 Caetano LC, Fujinaga CI, Scochi CGS. Sucção não nutritiva em bebês prematuros: estudo bibliográfico. Rev Latino-Am Enfermagem. 2003;11(2):232-6. , 2929 Neiva FCB, Leone CR. Efeitos da sucção não-nutritiva na idade de início da alimentação via oral em recém-nascidos pré-termo. Rev Paul Pediatria. 2007;25(2):129-34. ) suggest that the speech therapy performance in the transition from gastric feeding to oral feeding can start with corrected gestational age between the 32 nd and 34 th week and, in case of the population here studied, the CGA average, both group 1 and group 2 were in agreement according with the literature. In contrast, in similar study ( 1919 Medeiros AMC, Oliveira ARM, Fernandes AM, Guardachoni GAS, Aquino JPSP, Rubinick ML, et al. Caracterização da técnica de transição da alimentação por sonda enteral para seio materno em recém-nascidos prematuros. J Soc Bras Fonoaudiol. 2011;23(1):57-65. ) with preterm infants nonparticipants in kangaroo method, were observed higher average (35,29 weeks) than indicated by the literature and in this study, in order to start the speech therapy, being this average considered late, since the method allows speech intervention on the transition probe removal to oral feeding offer occurs at an early age ( 2222 Brasil, Ministério da Saúde, Secretaria de Atenção à Saúde. Atenção humanizada ao recém-nascido de baixo peso - Método Canguru: 2 a. ed. Brasília: Ministério da Saúde; 2011. (Série A. Normas e manuais técnicos, 145). ) , and consequently, the effective breastfeeding exclusively breastfed. However, as the weight seems to have been a major feature at the beginning of the assessment, gestational age was not a restriction parameter, given that this agrees with studies ( 1818 Bühler KEB, Limongi SCO. Fatores associados à transição da alimentação via oral em recém-nascidos pré-termo. Pró-Fono R Atual Cient. 2004;16(3):301-10. , 1919 Medeiros AMC, Oliveira ARM, Fernandes AM, Guardachoni GAS, Aquino JPSP, Rubinick ML, et al. Caracterização da técnica de transição da alimentação por sonda enteral para seio materno em recém-nascidos prematuros. J Soc Bras Fonoaudiol. 2011;23(1):57-65. ) that indicate that there is a tendency to intervene at an early age in aspects that relate to sucking and feeding stimulations, already with corrected gestational age of 32 to 34 weeks coinciding precisely with the profile of the population studied here.

Some authors ( 5Delgado SE, Halpern R. Amamentação de prematuros com menos de 1500 gramas: funcionamento motor-oral e apego. Pró-Fono R Atual Cient. 2005;17(2):141-52. , 1515 Lau C. [Development of oral feeding skills in the preterm infant]. Arch Pediatr 2007;14 Suppl 1:S35-41. Francês. , 2929 Neiva FCB, Leone CR. Efeitos da sucção não-nutritiva na idade de início da alimentação via oral em recém-nascidos pré-termo. Rev Paul Pediatria. 2007;25(2):129-34. , 3030 Moura LTL, Tolentino GM, Costa TLS, Aline A. Atuação fonoaudiológica na estimulação precoce da sucção não-nutritiva em recém-nascidos pré-termo. Rev CEFAC. 2009;11(3):448-56. ) believe, however, that before 34 weeks of gestational age, there is no S/S/B coordination. Despite the low gestational age at birth during the assessment (CGASTA), the newborns had safe average weight gain for the intervention of 35,10 weeks, confirming the literature ( 5Delgado SE, Halpern R. Amamentação de prematuros com menos de 1500 gramas: funcionamento motor-oral e apego. Pró-Fono R Atual Cient. 2005;17(2):141-52. , 1515 Lau C. [Development of oral feeding skills in the preterm infant]. Arch Pediatr 2007;14 Suppl 1:S35-41. Francês. , 2929 Neiva FCB, Leone CR. Efeitos da sucção não-nutritiva na idade de início da alimentação via oral em recém-nascidos pré-termo. Rev Paul Pediatria. 2007;25(2):129-34. , 3030 Moura LTL, Tolentino GM, Costa TLS, Aline A. Atuação fonoaudiológica na estimulação precoce da sucção não-nutritiva em recém-nascidos pré-termo. Rev CEFAC. 2009;11(3):448-56. ) , and would have appropriate maturational conditions to begin swallowing training.

Statistically, there was significant difference in the parameters for the CGA during the assessment and CGA at the initiation of the diet by OV, coinciding with the literature ( 1212 Almeida MNF, Siqueira TO, Ribeiro SMM. Avaliação da oclusão no período pré-dentário em prematuros nascidos na Fundação Santa Casa de Misericórdia do Pará. Rev Para Med. 2007;21(4):31-6. , 1414 Calado DFB, Souza R. Intervenção fonoaudiológica em recém-nascido pré-termo: estimulação oromotora e sucção não-nutritiva. Rev CEFAC. 2012;14(1):176-81. ) , which indicates that, from the 34 th week, the baby would be able to coordinate the S/S/B movements. In this study, both groups started in “partially filled breast”, gestational age close to what the authors claim as indicated.

Regarding to days in speech therapy, there was no difference between groups, as shown by the results. However, when the data are understood clinically, an average of three days apart spent in speech therapy can be important, when it comes to the sensory and motor abilities of the newborn. Early discharge may favor the decreasing of length of hospital stay, the risk of infection inherent in this environment, even influencing the mother/family’s psychological conditions and contributing to maternity´s cost reduction ( 5Delgado SE, Halpern R. Amamentação de prematuros com menos de 1500 gramas: funcionamento motor-oral e apego. Pró-Fono R Atual Cient. 2005;17(2):141-52. ) .

CONCLUSION

The study helped to clarify the importance of early speech therapy in neonatal units, specially in kangaroo units, once, when using the feeding transition technique from probe straight to breast in newborns in risk with similar gestational age average and at the same time be on speech therapy, the infants demonstrated the ability to coordinate sucking/breathing and swallowing movements, and consequently, the effective exclusively breastfeeding.

It is suggested to conducted further studies using the transition technique from probe to breast in neonates and low birth weight premature within the various neonatal units in order to attend to the importance of speech therapy in these units and thereby ensuring humanized care of these individuals and their families.
