Association between early pregnant hospitalization and use of obstetric interventions and cesarean: a cross-sectional study.

OBJECTIVE: Evaluate the association between early pregnant hospitalization and the use of obstetric interventions and cesarean delivery route. METHODS: Cross-sectional study, with 758 women selected at the time of childbirth. It was assumed as early hospitalization when the woman was admitted to the hospital having less than 6 cm of cervical dilation. Logistic regression models were constructed in order to estimate the odds ratio for each obstetric intervention, adjusted by sociodemographic and obstetric variables. RESULTS: 73.22% of women were early hospitalized. On average, they had 1.97 times the chance to undergo Kristeller's maneuver, 2.59 and 1.80 times the chance to receive oxytocin infusion and analgesia, respectively, and 8 times more chances to having their children by cesarean delivery when compared to women that had timely hospitalization. CONCLUSION: Early hospitalized women were submitted to a higher number of obstetric intervention and had increased chances of undergoing cesarean sections.

RESUMEN Objetivo: Evaluar relación entre internación precoz de embarazadas y uso de intervenciones obstétricas y vía de nacimiento cesariana. Métodos: Estudio transversal, con 758 mujeres seleccionadas por ocasión de realización de parto. Se asumió como internación precoz cuando la mujer ha sido admitida en hospital teniendo menos que 6 cm de dilatación cervical. Han construidos modelos de regresión logística para estimar la odds ratio para cada intervención obstétrica, ajustados por variables sociodemográficas y obstétricas. Resultados: De las mujeres, 73,22% se internaron precozmente. En media, estas tuvieron 1,97 veces la chance de sufrieren la maniobra de Kristeller, 2,59 y 1,80 veces la chance de recibir la infusión de oxitocina y analgesia, respectivamente, y 8 veces más chances de tener sus hijos por cesariana cuando comparadas a las mujeres que tuvieron internación oportuna. Conclusión: Mujeres internadas precozmente se someten a un mayor número de intervención obstétrica y tuvieron chances aumentadas de sufrir cesarianas.

RESUMO Objetivo: Avaliar a associação entre a internação precoce de gestantes e o uso de intervenções obstétricas e via de nascimento cesariana. Métodos: Estudo transversal, com 758 mulheres selecionadas por ocasião da realização de parto. Assumiu-se como internação precoce quando a mulher foi admitida no hospital tendo menos que 6 cm de dilatação cervical. Foram construídos modelos de regressão logística para estimar a odds ratio para cada intervenção obstétrica, ajustados pelas variáveis sociodemográficas e obstétricas. Resultados: Das mulheres, 73,22% foram internadas precocemente. Em média, estas tiveram 1,97 vezes a chance de sofrerem a manobra de Kristeller, 2,59 e 1,80 vezes a chance de receberem a infusão de ocitocina e analgesia, respectivamente, e 8 vezes mais chances de terem seus filhos por cesariana quando comparadas às mulheres que tiveram a internação oportuna. Conclusão: Mulheres internadas precocemente foram submetidas a um maior número de intervenção obstétrica e tiveram chances aumentadas de sofrerem cesarianas.
