Anesthetic management of patients with class 3 obesity undergoing elective Cesarean delivery: a single-centre historical cohort study
Authors' conclusion
Neuraxial anesthesia was successfully used in approximately 98% of patients with class 3 obesity undergoing elective Cesarean delivery. The choice of regional anesthesia technique varied with increasing BMI and with the planned surgical incision. Procedural times increased with increasing BMI.
