Objectif : Évaluer l’effet de la cardiotocographie à l’admission (ACTG) par rapport à l’auscultation intermittente (IA) du cœur fœtal (FH) dans les grossesses à faible risque au cours de l’évaluation du travail éventuel sur les taux de césariennes.
Conception : Un essai randomisé multicentrique parallèle.
Réglage : Trois maternités en République d’Irlande.
Population : Des femmes enceintes en bonne santé et à faible risque, à terme et âgées de 18 ans et plus, qui ont fourni un consentement éclairé écrit.
Méthodes: Les femmes ont été randomisées pour recevoir IA de la FH ou 20 minutes d’ACTG à l’admission pour une possible apparition du travail, en utilisant la randomisation téléphonique à distance. Les deux groupes ont reçu une IA pendant le travail, la conversion en CTG continu étant indiquée cliniquement.
Principales mesures de résultat: Césarienne (résultat primaire), interventions obstétricales (par exemple, CTG continu pendant le travail, prélèvement de sang fœtal, augmentation du travail) et morbidité néonatale (par exemple acidose métabolique, admission à l’unité de soins intensifs néonatals, décès néonatal).
Résultats : Sur la base de 3034 femmes (1513 et 1521 randomisés pour IA et ACTG respectivement), il n’y avait pas de différence statistique entre les groupes césariennes (respectivement 130 (8,6%) et 105 (6,9%) pour les groupes IA et ACTG; risque relatif (RR) 1,24; intervalle de confiance à 95% (IC) de 0,97 à 1,58) ou dans tout autre résultat, sauf pour l’utilisation de la CTG continue pendant le travail, qui était inférieure dans le groupe IA (RR 0,90, IC 95% 0,86-0,93).
Conclusion : Notre étude ne montre aucune différence dans les résultats obstétricaux ou néonatals entre l’IA et l’ACTG chez les femmes présentant un risque d’apparition de travail autre qu’un risque accru de CTG continue chez les femmes recevant ACTG.
Abstract (English)
:
Objective : To assess the effect of admission cardiotocography (ACTG) versus intermittent auscultation (IA) of the fetal heart (FH) in low‐risk pregnancy during assessment for possible labour on caesarean section rates.
Design : A parallel multi‐centre randomised trial.
Setting : Three maternity units in the Republic of Ireland.
Population : Healthy, low‐risk pregnant women, at term and ≥18 years, who provided written informed consent.
Methods : Women were randomised to receive IA of the FH or 20 minute ACTG on admission for possible labour onset, using remote telephone randomisation. Both groups received IA during labour, with conversion to continuous CTG as clinically indicated.
Main outcome measures : Caesarean section (primary outcome), obstetric interventions (e.g. continuous CTG during labour, fetal blood sampling, augmentation of labour) and neonatal morbidity (e.g. metabolic acidosis, admission to the neonatal intensive care unit, neonatal death).
Results : Based on 3034 women (1513 and 1521 randomised to IA and ACTG, respectively), there was no statistical difference between the groups in caesarean section (130 (8.6%) and 105 (6.9%) for IA and ACTG groups, respectively; relative risk (RR) 1.24; 95% confidence interval (CI) 0.97 to 1.58), or in any other outcome except for use of continuous CTG during labour, which was lower in the IA group (RR 0.90, 95% CI 0.86‐0.93).
Conclusion : Our study demonstrates no differences in obstetric or neonatal outcomes between IA and ACTG for women with possible labour onset, other than an increased risk for continuous CTG in women receiving ACTG.
Sumário (português)
:
Objetivo : Avaliar o efeito da cardiotocografia de admissão (ACTG) versus ausculta intermitente (IA) do coração fetal (FH) na gravidez de baixo risco durante a avaliação para possível trabalho de parto em taxas de cesariana.
Desenhar : Um estudo randomizado multicêntrico paralelo.
Configuração : Três maternidades na República da Irlanda.
População : Gestantes saudáveis e de baixo risco, a termo e ≥18 anos, que forneceram consentimento informado por escrito.
Métodos : As mulheres foram randomizadas para receber IA da HF ou ACTG de 20 minutos na admissão para possível início de parto, usando randomização por telefone remoto. Ambos os grupos receberam AI durante o trabalho de parto, com conversão para CTG contínua conforme indicação clínica.
Medidas de saída principais : Cesariana (desfecho primário), intervenções obstétricas (por exemplo, CTG contínuo durante o trabalho de parto, amostragem de sangue fetal, aumento do trabalho) e morbidade neonatal (por exemplo, acidose metabólica, internação na unidade de terapia intensiva neonatal, morte neonatal).
Resultados : Com base em 3034 mulheres (1513 e 1521 randomizadas para IA e ACTG, respectivamente), não houve diferença estatística entre os grupos na cesariana (130 (8,6%) e 105 (6,9%) nos grupos IA e ACTG, respectivamente; risco relativo (RR) 1,24, intervalo de confiança de 95% (IC) 0,97 a 1,58), ou em qualquer outro desfecho, exceto o uso de CTG contínuo durante o trabalho de parto, que foi menor no grupo IA (RR 0,90, IC95% 0,86-0,93).
Conclusão: Nosso estudo demonstra que não há diferenças nos resultados obstétricos ou neonatais entre IA e ACTG para mulheres com possível início de parto, além do aumento do risco de CTG contínuo em mulheres que recebem ACTG.
