Observational study investigates the impact of abdominal circumference on anesthetic spread in parturients, revealing no correlation.

This research aims to investigate how abdominal circumference affects the spread of intrathecal heavy bupivacaine during cesarean sections.
Enrolled 78 parturient women with singleton gestation undergoing cesarean section under spinal anesthesia.
Measured abdominal circumference before administering 2 mL of 0.5% heavy bupivacaine via lumbar puncture at L3-L4.
Assessed sensory block level through cold-sensation loss at various time intervals post-anesthesia.
No correlation was found between abdominal circumference and the level of cold sensation loss.
Adverse effects were reported: hypotension (44.4%), bradycardia (4.2%), nausea (4.2%), vomiting (2.8%), and shivering (18.1%).

Silwal et al. (2026) studied this question.
