Objective:
The 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.
Methods:
This 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.
Results:
Most 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.
Conclusions:
In 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.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
