Repercussions of SARS-CoV-2 infection and the pandemic on birth routes: a cross-sectional study

Repercusiones de la infección por SARS-CoV-2y la pandemia en las vías de nacimiento: un estudio transversal

ABSTRACT

Objective:

To assess the repercussions of SARS-CoV-2 infection (suspected or confirmed) and the context of the pandemic on the birth route and humanized assistance during childbirth.

Method:

Cross-sectional epidemiological study, nested within a cohort and comparative with the research “Birth in Belo Horizonte: Survey on Childbirth and Delivery”.The medical records of three reference maternity hospitals in Belo Horizonte were assessed, with a final sample of 1,682 pregnant women, in the months of May, June and July 2020. A descriptive analysis was carried out, with absolute and relative frequency, and a comparative one, with a Pearson’s chi-square test.

Results:

It was observed that 2.02% of pregnant women were infected with SARS-CoV-2.Before the pandemic, out of a total of 390 pregnant women, 74.10% gave birth vaginally.During a pandemic, among infected women, 51.61% gave birth via cesarean section and 48,39% via vaginal delivery;among uninfected, 26.99% cesarean sections and 73.01% vaginaldeliveries.

Conclusion:

There was an increase in the percentage of cesarean sections and a possible influence of the pandemic on the rates of indication of cesarean sections at the time of admission to the maternity ward.

INTRODUCTION

At the end of 2019, in the city of Wuhan, there was the emergence of a new virus called Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), and its clinical manifestation is called Coronavirus disease (COVID-19), classified as a pandemic in 2020 by the World Health Organization (WHO)11. World Health Organization. Coronavirus disease 2019 (COVID-19) Situation Report - 51 [Internet]. Geneva: WHO; 2020 [cited2022 Feb 09].

. Since then, with the advancement of the disease, controversies or actions in the opposite direction of the evidence regarding assistance during labor, delivery and birth have been observed, making this scenario challenging22.

https://doi.org/10.34119/bjhrv3n6-232...
.

Until February 24, 2023, 24,212 cases of Severe Acute Respiratory Syndrome (SARS) due to COVID-19 were reported in Brazil in pregnant and postpartum women in a non-pregnant population of 2,168,166 individuals, which corresponds to 1% of cases in pregnant and postpartum women33. Observatório Obstétrico Brasileiro [Internet]. OOBR; 2022 [cited 2023 Feb 24]. Informações Gerais. Available from: https://observatorioobstetrico.shinyapps.io/covid_gesta_puerp_br/
https://observatorioobstetrico.shinyapps...
. Regarding the state of Minas Gerais, 1,918 cases of pregnant women with SARS caused by COVID-19 were reported, and in Belo Horizonte, there were 195 cases44.

https://observatorioobstetrico.shinyapps...
. However, it is believed that these rates may be higher due to underreporting, low performance of laboratory tests and possible false negatives55. Souza ASR, Amorim MMR. Maternal mortality by COVID-19 in Brazil. Rev Bras Saúde Mater Infant. 2021;21(Suppl 1):257-61. doi: https://doi.org/10.1590/1806-9304202100s100014
https://doi.org/10.1590/1806-9304202100s...
. Furthermore, in Brazil, universal testing was not adopted as a health policy during the pandemic, which leads to a lower number of cases in relation to the infected population66. Knobel R, Takemoto MLS, Nakamura‐Pereira M, Menezes MO, Borges VK, Katz L, et al. COVID‐19‐related deaths among women of reproductive age in Brazil: the burden of postpartum.

https://doi.org/10.1002/ijgo.13811...
.

Initially, it was believed that pregnant women had an infection similar to that developed in the non-pregnant population, however, a study shows that pregnant women are at increased risk of developing complications and needing assistance in the Intensive Care Unit (ICU), in addition to death rates increase, especially in places with flaws in the health system and lower income55. Souza ASR, Amorim MMR. Maternal mortality by COVID-19 in Brazil. Rev Bras Saúde Mater Infant. 2021;21(Suppl 1):257-61. doi: https://doi.org/10.1590/1806-9304202100s100014
https://doi.org/10.1590/1806-9304202100s...
. According to the evidence found so far, implications of SARS-CoV-2 in pregnancy, childbirth and the postpartum, even if the infected pregnant woman remains asymptomatic, may be associated with an increased risk of clinical complications during pregnancy77.

Throughout pregnancy, the woman’s body undergoes several changes in its physiology, to maintain homeostasis and protection for the woman and the fetus88. Albuquerque LP, Monte AVL, Araújo RMS. Implicações da COVID-19 para pacientes gestantes. Rev Eletr Acervo Saúde. 2020;12(10):e4632. doi: https://doi.org/10.25248/reas.e4632.2020
https://doi.org/10.25248/reas.e4632.2020...
. Some of these changes may be related to the worsening of the COVID-19 condition in pregnant women88. Albuquerque LP, Monte AVL, Araújo RMS. Implicações da COVID-19 para pacientes gestantes. Rev Eletr Acervo Saúde. 2020;12(10):e4632. doi: https://doi.org/10.25248/reas.e4632.2020
https://doi.org/10.25248/reas.e4632.2020...
. This fact could explain the high mortality rates due to COVID-19 in pregnant women and postpartum women in Brazil99. Amorim MMR, Soligo Takemoto MLS, Fonseca EB. Maternal deaths with coronavirus disease 2019: a different outcome from low- to middle-resource countries? Am J Obstet Gynecol. 2020;223(2):298-9. doi: https://doi.org/10.1016/j.ajog.2020.04.023

.

Regarding labor and delivery, in Brazil, there have been intense investments, public policies and the training of professionals to change the delivery and birth care model in the COVID-19 pre-pandemic period1010. Ministério da Saúde (BR). Secretaria de Ciência, Tecnologia e Insumos Estratégicos. Departamento de Gestão e Incorporação de Tecnologias em Saúde. Diretrizes nacionais de assistência ao parto normal: versão resumida [Internet]. Brasília, DF: Ministério da Saúde; 2017 [cited 2022 Mar 16].

http://bvsms.saude.gov.br/bvs/publicacoe...
. However, the advances achieved in the Brazilian obstetric scenario before the COVID-19 pandemic may have suffered setbacks as a result of the pandemic period also experienced in Brazil, with the increasing use of interventional methods without evidence of clinical indication during delivery, such as labor induction and cesarean section as the adopted birth route1111. Lalor J, Ayers S, Celleja Agius J, Downe S, Gouni O, Hartmann K, et al. Balancing restrictions and access to maternity care for women and birthing partners during the COVID‐19 pandemic: the psychosocial impact of suboptimal care.

.

On the other hand, in Brazil, the Brazilian Federation of Gynecology and Obstetrics Associations (Federação Brasileira das Associações de Ginecologia e Obstetrícia - FEBRASGO) advised that the route of birth should be decided according to the clinical conditions of the pregnant woman and the fetus, and infection by SARS-CoV-2 should not be a determinant in the choice of birth route and cesarean section should only be used in pregnant women with a severe clinical condition1212. Trapani Júnior A, Vanhoni LR, Marcolin AC, Silveira SK. Protocolo de atendimento no parto, puerpério e abortamento durante a pandemia da COVID-19. Femina. 2020 [cited 2022 Mar 16];48(6):326-333.

.

Due to the COVID-19 pandemic, it was necessary to adapt health services in the world and also in Brazil, since the epidemiological situation and the natural history of the disease required the modification of protocols, the organization of services and flows1313.

. Among the different lines of care, pregnant women, puerperal women and newborns also suffered with the impacts of these changes, especially because the disease is new and does not allow a clear view of its outcomes1414. Ministério da Saúde (BR). Secretaria de Atenção Primária à Saúde. Departamento de Ações Programáticas e Estratégicas. .

.

Thus, the hypothesis of this work is that the COVID-19 pandemic caused interference in labor and in the birth route of all parturients, especially in pregnant women infected with SARS-CoV-2. There was a gap in the literature on the subject, which showed the need for research that could clearly demonstrate the Brazilian reality regarding repercussions of COVID-19 on birth routes during the pandemic. Therefore, the present study aims to assess the repercussions of SARS-CoV-2 infection (suspected or confirmed) and the context of the pandemic in the birth routes and in the humanized assistance to childbirth.

METHOD

This is a study based on the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines, conducted with preliminary data from the survey “Childbirth and breastfeeding in children of mothers infected with SARS-CoV-2”, a cross-sectional study, nested in a cohort and comparison with data from the research entitled “Birth in Belo Horizonte: Inquiry on Labor and Birth”, conducted in the pre-pandemic period of COVID-19.

Inquiry “Childbirth and breastfeeding in children of mothers infected with SARS-CoV-2”

The research was conducted in three reference maternity hospitals in the city of Belo Horizonte - Minas Gerais (MG), with data collection in 2021 and 2022. These institutions were chosen because they are references in the care for women and newborns and, for having as a philosophy the humanized care of labor and birth.

Regarding the sample selection, the period with the highest incidence of COVID-19 cases was chosen for the analysis of medical records, which were the months of May, June and July 2020. Among these medical records, those that met the inclusion criteria were selected, which included all singleton pregnant women who gave birth in a hospital and had newborns (NB) with a gestational age of 22 weeks or more, weighing more than 500 grams at birth and being alive; women under the age of 18 were excluded. Finally, the parturients were randomly selected from the birth record book and, subsequently, their medical records, available at the hospitals, were evaluated.

Regarding sample calculation, the cohort study design was used, considering a ratio of nine pregnant women for the control group (pregnant women not exposed to COVID-19) for each pregnant woman in the case group (woman exposed to COVID-19), due to the infection rate of 10% during the epidemic period1515. Perlman J, Oxford C, Chang C, Salvatore C, Di Pace J. Delivery room preparedness and early neonatal outcomes during COVID-19 pandemic in New York City. Pediatrics. 2020;146(2):e20201567. doi: https://doi.org/10.1542/peds.2020-1567
https://doi.org/10.1542/peds.2020-1567...
. To obtain a confidence level of 95% and power of 80%, an Odds Ratio of 1.5 was estimated. Thus, based on these parameters, an estimated sample of 1,893 pregnant women was obtained, with the distribution of pregnant women by maternity based on the total number of births in each selected maternity hospital. The final sample consisted of 1,682 pregnant women. In addition, regarding the demonstration of the data obtained, in some variables, the total value of the sample may not be equal to 1,682, as there was a lack of information in some variables in the collected medical records.

Data were collected from selected medical records of each institution under study by trained professionals. A structured physical questionnaire adapted from the research “Birth in Belo Horizonte: Inquiry on labor and birth” was used as a collection instrument. The activity of collection supervision was conducted by the team of researchers of the project and there was no payment for this purpose.

The collection instrument for the inquiry “Birth and breastfeeding of children of mothers infected with SARS-CoV-2” was composed of variables such as: clinical-obstetric background, assistance during labor and delivery at the participating institutions, birth routes, maternal clinical changes throughout hospitalization, breastfeeding in the first hour of life andsuspected or confirmed COVID-19 infection. Therefore, the following variables were used in this study: mother infected with SARS-CoV-2, parity, history of abortion, history of previous cesarean section, presence of clinical-obstetric complications, indication of cesarean section during hospitalization, presence of a companion during labor, use of non-pharmacological methods for pain relief, use of anesthesia, birth route and type of intercurrence. The variables parity, history of abortion and history of previous cesarean section were used only to describe the obstetric profile. In addition, the other variables were chosen, as they allow observing the correlation between the birth route and infection by SARS-CoV-2, in addition to demonstrating the level of obstetric interventions performed during labor and delivery1010.

.

The status of the woman’s SARS-CoV-2 infection was verified based on the medical records available in the hospitals, and in symptomatic women, the confirmatory test performed at the institution and its result were sought. In cases where this test was not available, pregnant women who presented symptoms suggestive of the infection at the time of admission were considered as suspect cases. It is worth noting that, in the Brazilian context, due to the reduced number of COVID-19 tests, only parturients who were admitted to hospitals with signs or symptoms of COVID-19 underwent confirmatory tests66.

Research “Birth in Belo Horizonte: Inquiry on labor and birth”

The research “Birth in Belo Horizonte: Inquiry on labor and birth” is a retrospective cohort, that had its data collection conducted from November 2011 to March 2013 (pre-pandemic) and was performed with women who were assisted in seven maternity hospitals in the public network and four in the supplementary network in Belo Horizonte, Minas Gerais1717.

https://doi.org/10.1590/0102-311x0017601...
.

The study “Birth in Belo Horizonte: Inquiry on labor and birth” adopted the same criteria as the “National Research: Birth in Brazil: national survey into labor and birth1616. World Health Organization. WHO recommendations: Intrapartum care for a positive childbirth experience [Internet]. Geneva: WHO; 2018 [cited 2022 Feb 09]. Available in: https://www.who.int/publications/i/item/9789241550215
https://www.who.int/publications/i/item/...
”. The sample selection of the study “Birth in Belo Horizonte: Inquiry on labor and birth” included women hospitalized at the time of delivery and their fetuses, alive or dead, with birth weight ≥ 500 g and/or gestational age ≥ 22 weeks of gestation. Women who did not understand Portuguese, indigenous, with severe intellectual disability, deaf, homeless or convicted by court decision were excluded1717. Vasconcellos MTL, Silva PLN, Pereira APE, Schilithz AOC, Souza PRBS Junior , Szwarcwald CL. Sampling design for the birth in Brazil: national survey into labor and birth.

https://doi.org/10.1590/0102-311x0017601...
. Among the maternity hospitals in the study “Birth in Belo Horizonte: Inquiry on labor and birth”, only data related to the same maternity hospitals selected in the study “Birth and breastfeeding in children of mothers infected with SARS-CoV-2” were used, the final sample consisted of 390 puerperal women who had their children in the three public hospitals1818. Menezes FR, Silva TPR, Felisbino-Mendes MS, Santos LC, Canastra MAAP, Filipe MML, et al. Influence of the COVID-19 pandemic on labor and childbirth care practices in Brazil: a cross-sectional study.

https://doi.org/10.1186/s12884-023-05358...
.

In this research, data collection was conducted from November 2011 to March 2013 by previously trained nurses. The interviews were conducted during the period of hospitalization of the woman, at least six hours after delivery, which was defined as the minimum time necessary for the puerperal woman to rest1717. Vasconcellos MTL, Silva PLN, Pereira APE, Schilithz AOC, Souza PRBS Junior , Szwarcwald CL. Sampling design for the birth in Brazil: national survey into labor and birth.

https://doi.org/10.1590/0102-311x0017601...
.

For comparison purposes, this study used data on the variables: birth route, use of anesthesia, use of non-pharmacological methods for pain relief (NPM), presence of a companion during labor and indication of cesarean section at the time of admission.

Data analysis

The data consistency was verified from a primary typing process, to find atypical data through the descriptive analysis of data and, if necessary, a conference was made in the data collection instrument. After this process, statistical analyzes were performed, which were initially characterized by a descriptive analysis using absolute and relative frequencies to describe the variables evaluated in the study. Differences between groups (uninfected and suspected or confirmed cases) were assessed using Pearson’s chi-square statistical test.

Subsequently, a comparison test was made between the variables from the Research Birth in Belo Horizonte database and the variables from the study “Birth and breastfeeding in children of mothers infected with SARS-CoV-2”, through Pearson’s chi-square statistical test, evaluating the variables only in the hospitals selected for this research in both databases. A comparison was made between the variables related to birth route and the humanized assistance to childbirth, namely: birth route, use of anesthesia, use of non-pharmacological methods for pain relief, presence of a companion during labor and delivery, and indication of cesarean section upon admission. The analyses were produced with Statistical Software for Professional (Stata), version 16.0.

Ethical aspects

The study “Birth and breastfeeding in children of mothers infected with SARS-CoV-2” was approved by the Ethics Committee of the Universidade Federal de Minas Gerais (UFMG) with protocol CAAE: 32378920.6.1001.51409, the use of FICF was not necessary due to the study design and period of data collection in the medical records.

The project “Birth in Belo Horizonte: Survey on Labor and Birth” was approved by the Ethics Committee of the Universidade Federal de Minas Gerais (UFMG), (Opinion no. CAAE - 0246.0.203.000-11). All puerperal women and directors of each maternity hospital signed the Free and Informed Consent Form, complied with the ethical guidelines described in Resolution no. 466, December 12, 2012, of the National Health Council, which provides for research with human beings.

RESULTS

This study consisted of 1,682 pregnant women and, of these women, 2.02% were suspected or infected with SARS-CoV-2; 61.65% were multiparous; 71.31% had no history of abortion; 72.80% had no history of previous cesarean sections; 53.78% had no clinical/obstetric complications; 85.34% had no indication for cesarean section during hospitalization; 88.83% were with a companion during labor; 66.54% used non-pharmacological methods; 71.70% did not use anesthesia; in addition, 72.75% of women delivered vaginally (Table 1).

Regarding comparison of data with the research “Birth in Belo Horizonte: Inquiry on labor and birth”, it was observed that, among the 390 births recorded in the hospitals in this research, 25.90% were by cesarean section. On the other hand, in the research conducted during the pandemic, among women infected by COVID-19, 51.61% had their children by cesarean section and, among those not infected, 73.01% gave birth vaginally, with a statistically significant difference (p=0.010).

Regarding the variable indication of cesarean section at delivery, in the research “Birth in Belo Horizonte: Inquiry on labor and birth”, 66.34% had no indication for cesarean section. In the present research during the pandemic, regarding infected women, 64.29% had no indication and, among uninfected women, 85.63% had no indication (p<0.001) (Table 3).

Furthermore, higher proportions of women who used non-pharmacological methods for pain relief in women with COVID-19 were observed when compared to non-infected women and women from the database “Birth in Belo Horizonte: Inquiry on labor and birth” (p<0.00).

DISCUSSION

This study allowed an assessment of the potential repercussions caused by COVID-19, in suspected and confirmed cases, on birth routes. There was a significant increase in the percentage of cesarean sections in infected women compared to pre-pandemic women. Especially at the beginning of the pandemic, there were no robust studies that discussed the increased risks of the pregnant woman and the fetus, which classified the pregnant woman at a risk equal to of a non-pregnant woman, and little subsidized the assistance aimed at them1919. Stanojević M. Are Covid-19-positive mothers dangerous for their term and well newborn babies? is there an answer? J Perinat Med. 2020;48(5):441-5. doi: https://doi.org/10.1515/jpm-2020-0186
https://doi.org/10.1515/jpm-2020-0186...
. Therefore, it can be inferred that the scarcity of robust evidence regarding the consequences of infection in pregnant women may have led to an intensification of the cesarean section scenario.

In the obstetric context, the COVID-19 pandemic has overloaded health systems worldwide, especially in places where they have already experienced previous weaknesses, such as Brazil2020. World Health Organization [Internet]. Geneva: WHO; 2020 [cited 2023 Feb 21]. Coronavírus disease (COVID-19) pandemic. Available from: https://www.who.int/emergencies/diseases/novel-coronavirus-2019
https://www.who.int/emergencies/diseases...
. In this sense, these historical weaknesses in the Brazilian scenario, potentiate the excessive use of non-recommended practices and without scientific evidence during labor, delivery and birth, in addition to the high cesarean rates, although the WHO recommends that these rates not exceed 15% of assisted deliveries2121. Leal MC, Pereira APE, Domingues RMSM, Theme MM Filha , Dias MAB, Nakamura-Pereira M, et al. Obstetric interventions during labor and childbirth in Brazilian low-risk women. Cad Saude Publica. 2014 [cited 2022 Feb 09];30 (Suppl 1):S17-S32. Available from: https://www.scielo.br/scielo.php?script=sci_arttext&pid=S0102-311X2014001300005

.

The cesarean section is a surgery that should be based on real clinical indications, and aims to reduce maternal and perinatal morbidity and mortality if well recommended2323. Souza ASR, Amorim MMR, Porto AMF. Condições frequentemente associadas com cesariana, sem respaldo científico: [revisão]. Femina. 2010 [cited 2022 Aug 31];38(10):505-16. Available from: http://files.bvs.br/upload/S/0100-7254/2010/v38n10/a1708.pdf
http://files.bvs.br/upload/S/0100-7254/2...
. It should be noted that the use of false indications often supports this procedure2424. Câmara R, Burlá M, Ferrari J, Lima L, Amim J Junior , Braga A, et al. Cesarean section by maternal request. Rev Col Bras Cir.2016;43(4):301-10. doi: https://doi.org/10.1590/0100-69912016004002
https://doi.org/10.1590/0100-69912016004...
. Based on this aspect, the real indications can be divided into absolute and relative. Regarding the absolute indications, cord prolapse is indicated; placental abruption with live fetus; partial or total placenta previa; vasa previa rupture; and genital herpes with an active lesion at labor2525. Silva TPR, Dumont-Pena É, Sousa AMM, Amorim T, Tavares LC, Nascimento DCP, et al. Obstetric nursing in best practices of labor and delivery care. Rev Bras Enferm. 2019;72(Suppl 3):235-42. doi: https://doi.org/10.1590/0034-7167-2018-0561
https://doi.org/10.1590/0034-7167-2018-0...
.

In view of these indications based on scientific evidence, it is necessary to carefully assess whether the high rate of indication for cesarean section in infected women at admission is related to the presence of COVID-19, since the infection should not be a justification for carrying out the birth through this birth route, but the general picture of the mother and the fetus1111. Lalor J, Ayers S, Celleja Agius J, Downe S, Gouni O, Hartmann K, et al. Balancing restrictions and access to maternity care for women and birthing partners during the COVID‐19 pandemic: the psychosocial impact of suboptimal care. BJOG. 2021;128(11):1720-5. doi: https://doi.org/10.1111/1471-0528.16844
https://doi.org/10.1111/1471-0528.16844...
. This need for assessment can be reinforced by the fact that 53.78% of the women in the group observed during the pandemic had no history of clinical-obstetric complications, which corroborates the suspicion that the pandemic context may be related to the increase in rates of cesarean section indication. Another factor that strengthens this hypothesis is the fact that few women had an absolute or relative clinical-obstetric intercurrence indicative of a cesarean section, such as HIV infection, fetal distress, placenta previa and/or placental abruption (PA).

In 2018, the WHO released the document of recommendations for care during labor, delivery and childbirth called Intrapartum care for a positive childbirth experience, with the aim of making the experience of childbirth positive, to improve physical, mental, and psychological outcomes for the woman, newborn, and family. This document places this core at the center of the care provided, by including them in conscious decision-making throughout the process1616. World Health Organization. WHO recommendations: Intrapartum care for a positive childbirth experience [Internet]. Geneva: WHO; 2018 [cited 2022 Feb 09]. Available in: https://www.who.int/publications/i/item/9789241550215

,2121. Leal MC, Pereira APE, Domingues RMSM, Theme MM Filha , Dias MAB, Nakamura-Pereira M, et al. Obstetric interventions during labor and childbirth in Brazilian low-risk women. Cad Saude Publica. 2014 [cited 2022 Feb 09];30 (Suppl 1):S17-S32. Available from: https://www.scielo.br/scielo.php?script=sci_arttext&pid=S0102-311X2014001300005
https://www.scielo.br/scielo.php?script=...
.

In this sense, before the pandemic, in Brazil, there was a predominance of inadequate obstetric care during labor, delivery and childbirth, which resulted in the excessive use of interventions and the high number of elective cesarean births2525. Silva TPR, Dumont-Pena É, Sousa AMM, Amorim T, Tavares LC, Nascimento DCP, et al. Obstetric nursing in best practices of labor and delivery care. Rev Bras Enferm. 2019;72(Suppl 3):235-42. doi: https://doi.org/10.1590/0034-7167-2018-0561
https://doi.org/10.1590/0034-7167-2018-0...
. Although assistance in labor and delivery of parturients positive for COVID-19 recommends more rigorous monitoring during the labor and delivery process, this does not mean that the behavior of professionals who assist them should be interventionist more than what is recommended in the scientific literature during this period and necessary according to the condition of the pregnant woman.

It is known that recommended practices during labor, delivery and newborn care is directly related to the improvement of obstetric outcomes2222. Organização Mundial da Saúde. Declaração da OMS sobre Taxas de Cesáreas [Internet].Brasília, DF: OMS; 2015 [cited 2022 Aug 31]. Available from: https://apps.who.int/iris/bitstream/handle/10665/161442/WHO_RHR_15.02_por.pdf?sequence=3
https://apps.who.int/iris/bitstream/hand...
. However, in the pandemic, the focus of care changed from that centered on women to their safety needs2020. World Health Organization [Internet]. Geneva: WHO; 2020 [cited 2023 Feb 21]. Coronavírus disease (COVID-19) pandemic. Available from: https://www.who.int/emergencies/diseases/novel-coronavirus-2019
https://www.who.int/emergencies/diseases...
. In Brazil, and in several countries, maternity hospitals (or normal delivery centers) have been defined as the best place to treat suspected and/or confirmed cases of SARS-CoV-2. They were chosen because they provide specific environments for vaginal delivery, cesarean sections, neonatal isolation in the Intensive Care Unit (ICU) or intermediate care and rooming-in2626. Poon LC, Yang H, Dumont S, Lee JCS, Copel JA, Danneels L, et al. ISUOG interim guidance on coronavirus disease 2019 (COVID-19) during pregnancy and puerperium: information for healthcare professionals: an update. Ultrasound Obstet Gynecol. 2020;55(6):848-62. doi: https://doi.org/10.1002/uog.22061
https://doi.org/10.1002/uog.22061...
.

Other variables in this study can also be considered as indicative of the process of instrumentalization and humanization of childbirth, such as the use of anesthesia; use of non-pharmacological methods for pain relief; and presence of a companion during labor. Regarding the use of anesthesia, authors associate it with some undesirable outcomes, such as the extension of the second stage of labor, increased need for oxytocin during labor, deficit in maternal motor function and rotational dystocia, although the evidence is not uniform and the statistical and clinical relevance are variable2727. Leão BCC. Influência da analgesia de parto no desfecho obstétrico: estudo em uma maternidade pública brasileira [dissertação]. Belo Horizonte: Universidade Federal de Minas Gerais; 2016 [cited 2022 Aug 31]. Available from: http://hdl.handle.net/1843/BUOS-AJNP8R
http://hdl.handle.net/1843/BUOS-AJNP8R...
.

In that regard, the need for tools with fewer negative impacts and risks of undesirable outcomes is evident, which can reduce the pain and discomfort of the pregnant woman, such as NPMs, which are behaviors administered throughout labor and delivery with the objective of reducing the pain of the laboring woman, seeking to perform the minimum of interventions and reduce the use of drugs2828. Mafetoni RR, Shimo AKK. Métodos não farmacológicos para alívio da dor no trabalho de parto: revisão integrativa. Rev Min Enferm. 2014 [cited 2022 Aug 31];18(2):505-12. Available from http://www.revenf.bvs.br/pdf/reme/v18n2/v18n2a18.pdf
http://www.revenf.bvs.br/pdf/reme/v18n2/...
. These methods are essential for the comfort of women during labor and the reduction of traumatic experiences, in addition to reducing interventions, which are responsible for more experience of pain and discomfort2929. Dodou HD, Rodrigues DP, Guerreiro EM, Guedes MVC, Lago PN, Mesquita NS. The contribution of the companion to the humanization of delivery and birth: perceptions of puerperal women. Esc Anna Nery. 2014;18(2):262-9. doi: https://doi.org/10.5935/1414-8145.20140038
https://doi.org/10.5935/1414-8145.201400...
.

Thus, the data from the present study allowed us to observe that, despite the negative impacts caused by COVID-19, the use of good practices in assisting pregnant women, in terms of pain relief, did not suffer considerable impacts, which may have mitigated the harmful effects of the medicalization of labor and delivery.

Finally, regarding the variable presence of a companion during labor, having emotional and physical support leads to a reduction in the feeling of loneliness; promotion of humanized delivery and birth; reduction of pharmacological methods for pain relief, the duration of labor, the number of cesarean sections and cases of postpartum depression, in addition to increasing women’s confidence and safety2929.

.

Before the COVID-19 pandemic, 95.90% of the women had a companion and, during this period, 88.83% were accompanied, and among infected women, 86.36% had a companion and 88.87% of those not infected were accompanied. However, considering that Law No. 11,108/2005 guarantees pregnant women the right to have a companion during labor and delivery, a percentage close to 100% is expected both in the pre-pandemic period and during the pandemic3131. Presidência da República (BR). Casa Civil. Subchefia para Assuntos Jurídicos. Lei nº 11.108, de 7 de abril de 2005. Altera a Lei nº 8.080, de 19 de setembro de 1990, para garantir às parturientes o direito à presença de acompanhante durante o trabalho de parto, parto e pós-parto imediato, no âmbito do Sistema Único de Saúde - SUS. Diário Oficial União. 2005 abr 8 [cited 2022 Oct 05];142(67 Seção 1):1. Available from: https://pesquisa.in.gov.br/imprensa/jsp/visualiza/index.jsp?jornal=1&pagina=1&data=08/04/2005&totalArquivos=176
https://pesquisa.in.gov.br/imprensa/jsp/...
.

Therefore, there was an increase in the number of cesarean sections in women infected with SARS-CoV-2, which can be explained, among other things, by the indication of cesarean sections as the first choice of birth route for infected women, without considering the clinical picture presented3232. Makara-Studzińska M, Zaręba K, Kawa N, Matuszyk D. Tokophobia and anxiety in pregnant women during the SARS-CoV-2 pandemic in Poland - a prospective cross-sectional study. Int J Environ Res Public Health. 2022;19(2):714. doi: https://doi.org/10.3390/ijerph19020714

https://doi.org/10.36553/wm.46...
.

Finally, some limitations of this study are highlighted, such as the non-representativeness of the population of pregnant women in Belo Horizonte. However, a rigorous methodology with the conduction of the study in three maternity hospitals specialized in childbirth care can minimize this limitation and contribute to generalizing the results.

It is understood that this study shows the impacts of the pandemic context in the assistance and care for pregnant women, parturients and puerperal women, which contributes to the knowledge advancement, in the perception of the fragility and susceptibility of assistance to women to the contexts faced, causing a negative impact on the care for pregnant women, parturients and postpartum women during the COVID-19 pandemic. Additionally, it contributes to the perspective of acting as a scientific framework for health professionals, as they pay attention to these issues and seek strategies that avoid the exacerbated use of practices without scientific evidence in the labor and delivery scenario.

Added to this, there are innovations for teaching, to show the need for investment in health education and permanent and continuing education, to reduce interventionist practices and to value the implementation of good practices in delivery and labor; for research, to be a ground instrument for the development of new, more comprehensive studies and to serve as a basis for comparison with data from other studies; for management, to allow the understanding of the professionals’ performance scenario and the improvement of financial and human resources; and for nursing and health care, to act as a scientific framework to defend good practices and encourage the search for scientific evidence to improve professional practice, respecting the centrality of obstetric care for women, newborns and families.

CONCLUSION

There was an increase in the percentage of cesarean sections in the maternity hospitals observed, as well as a possible influence of the pandemic on the rates of cesarean sections upon admission to the maternity hospital and on the use of non-pharmacological methods for pain relief.

In this context, it becomes necessary to strengthen health education practices, both for women (especially during prenatal care) and for professionals (especially those who provide labor and birth care), to provide the deconstruction of the hospital-centered model of health care; the reduction of unnecessary interventions; and the promotion of women’s active participation as the main agent in their care. It is hoped that this study can further strengthen the process of labor and delivery as physiological, in order to achieve the best outcome for the mother-baby binomial.
