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 degrees 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 degrees recommendation.
CONCLUSION
Estimation of the angle of table tilt is unreliable.
背景
产妇向一侧倾斜可减轻主动脉腔静脉受压及随之而来的心血管不稳定。
方法
我们测量了16名麻醉医生在进行简单择期剖宫产时使手术台倾斜的角度。开始麻醉后，要求他们摆放患者体位并估计倾斜角度，随后进行测量。
结果
几乎每位麻醉医生使患者倾斜的角度都小于15度，因为他们高估了倾斜角度。当被问及对当前侧倾建议的了解时，16名麻醉医生中有11人知晓15度的建议。
结论
手术台倾斜角度的估计不可靠。
