Intervenciones y complicaciones perinatales relacionadas al ingreso hospitalario durante la fase latente de la labor de parto. Revisión sistemática

Abstract

Background: The incidence of perinatal interventions and complications are more common in patients who hospitalized in the latent phase of labor. Current evidence suggest that latent phase is define as acervical dilatation less than 6 centimeters. General objective: To evaluate the perinatal interventions and complications related to hospitaladmission during the latent phase of labor. Methodology: observational, systematic review. The search terms used in English were “Labor Stage, First”, “Labor Onset”, “Patient Admission”, “Delivery, Obstetric”. Studies with full text, quintile one to two, with methodological, analytical, retrospective, prospective, descriptive designs between the years 1998-2020 were included. Results: admission in latent phase of labor is related to a higher risk of cesarean section (p <0.05), use of oxytocin during labor (p <0.05), epidural anesthesia (p <0.05), number of vaginalexaminations (p <0.05), and labor duration since admission (p <0.05). The variety of published results for the other interventions did not determine any other association. Conclusions: admission in latent phase of labor (<6 cm of dilation) is related to an increased risk of prolonged labor, number of vaginal examinations, epidural anesthesia, use of oxytocin tostimulate labor; and as a result the probability of cesarean section increases
