Analgesia in newborns: a case-control study of the efficacy of nutritive and non-nutritive sucking stimuli

Analgesia em recém-nascidos: um estudo caso-controle da eficácia dos estímulos de sucção nutritiva e não nutritiva

Abstracts

PURPOSE: To verify the nutritive and non-nutritive stimuli efficacy in the newborn's response to pain during venipuncture. METHODS: The main sample was composed of 64 newborns that were randomly divided into three groups. The first group (n=20) received nutritive sucking stimulus that was performed through maternal breastfeeding. The second group (n=21) received non-nutritive sucking stimulus that was performed through the introduction of the researcher little finger in the newborn's oral cavity. The third group or control group (n=23) did not receive any analgesia stimulus. The newborns were evaluated using the Neonatal Infant Pain Scale, and the responses to painful stimuli were compared. RESULTS: The nutritive as well as non-nutritive suction methods provided a comforting effect, resulting in lower pain response scores (p<0.05). There was no difference between the analgesia provided by both methods (p>0.05). CONCLUSION: The nutritive and the non-nutritive sucking stimuli proved to be efficacious tools in relieving pain among newborns.

OBJETIVO: Verificar a eficácia dos estímulos de sucção nutritiva e não nutritiva na resposta do recém-nascido à dor durante a punção venosa. MÉTODOS: A amostra principal foi composta por 64 recém-nascidos que foram divididos aleatoriamente em três grupos. O primeiro grupo (n=20) recebeu estímulo de sucção nutritiva, o qual foi realizado através da amamentação materna. O segundo grupo (n=21) recebeu estímulo de sucção não nutritiva, o qual foi realizado através da introdução do dedo mínimo do pesquisador na cavidade oral do recém-nascido. O terceiro grupo ou grupo de controle (n=23) não recebeu qualquer estímulo de analgesia. Os recém-nascidos foram avaliados utilizando a Escala de Dor do Recém-nascido e as respostas aos estímulos dolorosos foram comparadas. RESULTADOS: Ambos os estímulos de sucção proporcionaram efeito analgésico, resultando em respostas a dor menores se comparados ao controle (p<0.05). Não houve diferença entre a analgesia produzida pelos dois estímulos de sucção (p>0.05). CONCLUSÃO: Tanto o estímulo de sucção nutritiva quanto a sucção não nutritiva provaram ser métodos eficazes no alívio da dor em recém-nascidos.
