Summary
Brief summary
Hypotension occurs commonly following spinal anaesthesia. It is has been claimed that the standing posture prior to spinal anaesthesia may help prevent hypotension. The aim of this study is to compare two different postures prior to inducing spinal anaesthesia. One group of women will be lying down and the other group of women will be standing up prior to inducing spinal anaesthesia for caesarean section. We plan to measure any differences in the number of women requiring treatment for low blood pressure in the two groups.
