Key result
Left table tilt during Caesarean section eliminates the ~30% rate of intraoperative hypotension seen supine.
Why the study?
The effects of left tilt of the operating table on maternal hemodynamics and vasopressor requirement during caesarean section compared to supine position were unclear.
Does a 15° left tilt of the operating table improve maternal hemodynamics and reduce vasopressor requirement in women undergoing elective caesarean section under spinal anesthesia?
Population
38 participants undergoing elective caesarean section under spinal anesthesia
Comparison
Operating table tilted 15° to the left vs supine position after spinal anesthesia
Design
Comparative analytical study with randomization by lottery method

Does a 15° left tilt of the operating table improve maternal hemodynamics and reduce vasopressor requirement in women undergoing elective caesarean section under spinal anesthesia?
Absolute Event Rate: 0% vs 30%
A 15° left tilt of the operating table during caesarean section under spinal anesthesia significantly stabilizes maternal systolic blood pressure and eliminates the need for intraoperative vasopressors compared to the supine position.
Rizvi et al. (2023) conducted an RCT in Elective Caesarean section (n=38). 15° left tilt of operating table vs. Supine position was evaluated on Maternal hypotension incidence at 30 minutes. A 15° left tilt of the operating table during elective Caesarean section eliminated intraoperative hypotension (0% vs 30% at 30 minutes) and the need for intraoperative vasopressors compared to the supine position.
