Intraoperative hemodynamics and anesthetic implications in superobese parturients undergoing cesarean delivery: a retrospective cohort analysis.

Superobese parturients exhibited a delayed yet sustained decline in mean arterial pressure (mean arterial pressure) following neuraxial anesthesia, showing a late-phase, vasopressor-resistant hypotensive pattern.

Time from surgical procedure start to fetal delivery increased from 11.8 ± 9.1 min in normal weight versus 17.3 ± 9.3 min in superobese (p < 0.0001).

Between BMI groups, anesthesia start to procedure start, which reflected positioning, IV optimization, and neuraxial placement, increased from 35.1 ± 9.4 min to 50.6 ± 15.9 min (p < 0.0001), while total procedure time increased from 57.7 ± 24.3 to 76.8 ± 27.4 min (p < 0.0001).
