Key result
A 15° left lateral tilt does not alter maternal hemodynamics versus supine position during C-section.
Why the study?
Guidelines recommend a 12 to 15° tilt during Caesarean section under neuraxial blockade, but lesser, unmeasured degrees of tilt are often applied in practice, risking residual aortocaval compression and compromised maternal haemodynamics.
Does a 15° left lateral table tilt improve maternal haemodynamics compared to the supine position in full-term parturients undergoing elective Caesarean section under spinal anaesthesia?
Population
80 full-term singleton parturients scheduled for elective Caesarean delivery
Comparison

Design
Randomized controlled trial

15° left lateral tilt confers no haemodynamic benefit over supine in elective Caesarean section under spinal anaesthesia; challenges routine tilt recommendations and warrants reevaluation of positioning guidelines.

Does a 15° left lateral table tilt improve maternal haemodynamics compared to the supine position in full-term parturients undergoing elective Caesarean section under spinal anaesthesia?
A 15° left lateral tilt during elective Caesarean section under spinal anaesthesia did not significantly alter maternal haemodynamics compared to the supine position.
Tsai et al. (2018) conducted an RCT in Elective Caesarean delivery under spinal anaesthesia (n=80). 15° left lateral table tilt vs. Supine position was evaluated on Maternal haemodynamic variables (SBP, MAP, CI, and TPRI). A 15° left lateral table tilt did not significantly alter maternal haemodynamic parameters compared to the supine position in full-term parturients undergoing elective Caesarean section.
