Abstract

Introduction: Obese pregnant women, especially morbidly obese, are at greater risk of undergoing a cesarean section (CS). Clinical outcomes have been associated with an increase in body mass index (BMI). Objective: The objective of the study was to evaluate the sensory block level, the perioperative times, the incidence of maternal hypotension, the Apgar score, and the birth weight between the BMI strata of pregnant women undergoing CS. Method: In this prospective cohort study were included women with singleton pregnancies undergoing spinal anesthesia for elective CS. The pregnant women were classified according to BMI at delivery: normal (18.5–25 kg.m-2), overweight (25–29.9 kg.m-2), obese (30–39.9 kg.m-2), and morbidly obese (≥ 40 kg.m-2). The primary outcome was the total operative time. Results: Among 540 patients analyzed, 252 (46.7%) were obese and 54 (10%) were morbidly obese. The sensory block level (> T4) was higher in morbidly obese patients (18.5%) compared to patients with normal BMI (4%) and overweight (7.5%), p < 0.05. The median and interquartile range of the spinal-to-incision interval was longer in morbidly obese patients [13 (10–16.2) minutes] compared with normal BMI [10 (8–12) minutes] and overweight [10 (9.5–14) minutes], p < 0.000; and obese [11 (10–15) minutes], p < 0.00. Also, it was longer in obese patients compared with normal BMI, p < 0.00. The mean and standard deviation (SD) of the total operative time was longer in morbidly obese patients (70.2 ± 21 minutes) compared to those with normal BMI (59.7 ± 12 minutes) and overweight (61.3 ± 17 minutes), p < 0.00; and in obese (65.4 ± 18 minutes) compared with normal BMI, p < 0.05. The incidence of maternal hypotension was higher in morbidly obese patients (79.6%) compared with normal BMI (58.7%) and overweight (61%), p < 0.05; and in obese patients (71.8%) compared with normal BMI and overweight, p < 0.05. The birth weight of morbidly obese patients (3,553 ± 623 g) was higher than in patients with normal BMI (3,020 ± 626 g) and overweight (3,187 ± 587 g), p < 0.000; and in obese patients compared with normal BMI and overweight, p < 0.00. The incision-to-delivery interval, Apgar score < 7 at 5 minutes were similar in the different BMI strata. Conclusion: The increase in BMI is associated with longer perioperative times, higher sensory block level, higher incidence of maternal hypotension, and higher birth weight.
