ObjectiveThe main aim of this study was to evaluate the impact of using interventions in low- and high-risk parturients on maternal and perinatal adverse outcomes during labor.MethodsThis is a prospective study. The analyzed variables were obtained through a questionnaire with puerperal women (between 1- and 48-h postpartum) and through medical record searches. The study population was divided into two groups as follows: Group I included parturients who underwent at least one type of obstetric intervention and Group II included parturients who did not undergo any type of obstetric intervention.ResultsMost parturients (75.3%) underwent at least one type of intervention, with oxytocin being the most prevalent intervention (49.5%), followed by misoprostol use (28.7%), elective cesarean section at the request of the patient (23.0%), amniotomy (21.2%), and episiotomy (21.0%). Regarding the adverse perinatal outcomes related to low-risk pregnancies, the prevalence of the second- or third-degree perineal tears (17.8% vs. 36.7%, p=0.001) was lower in Group I than in Group II. Moreover, in high-risk pregnancies, the prevalence of hospitalization in the neonatal intensive care unit (2.8% vs. 16.7%, p<0.001), adult intensive care unit admission (0.8% vs. 3.9%, p=0.004), and the need for oxygen therapy (26.8% vs. 40.4%, p<0.001) was lower in Group I than in Group II.ConclusionsIn low-risk parturients, the interventions performed were associated with lower prevalence of second- or third-degree perineal tears. There was a lower prevalence of neonatal and adult intensive care unit admissions, the need for oxygen therapy, intracranial hemorrhage, and neonatal infection among high-risk parturients.
