Background. Lateral maternal tilt reduces aortocaval compression and the consequent cardiovascular instability.
Methods. We measured the angle of table tilt used by 16 anaesthetists during uncomplicated, elective Caesarean section. After initiating anaesthesia, they were asked to position the patient and estimate the angle of tilt, which was then measured.
Results. Almost every anaesthetist positioned the patient less than 15° because they overestimated the angle of tilt. When questioned on their knowledge of the current advice for lateral tilt, 11 of the 16 anaesthetists were aware of the 15° recommendation.
Conclusion. Estimation of the angle of table tilt is unreliable.
