The major inclusion criterion was admission with operation codes specific to cesarean section procedures (R4514, R4516, R4517, R4518, R4519, R4520, R4507, R4508, R4509, R4510, R5001, R5002). The study assessed mortality and pulmonary complications.

During the period, mortality were 0.05%. Overall and 30 days’ pulmonary complications were 1.06% and 0.15%. Mortality were increased in general anesthesia than regional anesthesia.
