Clinical Trial Summary

The goal of this observational study is to evaluate preoperative measures of abdominal circumference in patients admitted for a cesarean section. The main questions it aims to answer are:

• Can preoperative abdominal circumference predict patients with difficult spinal anesthesia

• Can preoperative abdominal circumference predict the occurrence of maternal hypotension during cesarean section Participants will be examined preoperatively in terms of visibility and palpation of spinous processes, abdominal circumference will be measured in the supine and sitting positions with other clinical parameters. Spinal anesthesia will be performed by the same experienced anesthesiologist with a standardized procedure. The number of skin punctures, needle reorientations, traumatic Cerebrospinal fluid, need for a paramedian approach or failure will be recorded. Maternal blood pressure and vasopressor requirements will also be monitored.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of patients with difficult spinal anesthesia	More than two needle reorientations in the first puncture or more than one skin puncture	During surgery
Secondary	Rate of Maternal hypotension	Systolic blood pressure below 90 mmHg or a drop of more than 20% of base value	The first hour after spinal anesthesia is performed
