Spinal anesthesia is the most commonly used technique for cesarean section. However, in obese parturients, identification of the optimal puncture site using anatomical landmark palpation can be challenging due to altered anatomy. Ultrasound has been proposed as a tool to improve localization of the puncture site. This study is a prospective randomized controlled trial including 100 obese parturients undergoing cesarean section under spinal anesthesia. Participants are randomly assigned to one of two groups: an ultrasound group, in which the puncture site is identified using preprocedural ultrasound, and a landmark group, in which the puncture site is determined using anatomical landmark palpation. The primary outcome is the first-attempt success rate. Secondary outcomes include the number of attempts, needle redirections, need for rescue interventions, incidence of adverse events during puncture, and procedural times.
