Spinal anesthesia is the method of choice for the cesarean section.

Gastric ultrasound is an emerging tool for preoperative evaluation of gastric content and volume. ⋯ Despite the differences in CSA between obese and normal-weight participants in both positions (obese > normal-weight), both groups showed a low predicted gastric residual volume < 1.5 mL/kg and were at low risk for aspiration, provided that fasting was initiated at least 8 hours before elective surgery.
