Randomized Controlled Trial Clinical TrialEffect of lateral versus supine wedged position on development of spinal blockade and hypotension.
Aortocaval compression may not be completely prevented by the supine wedged or tilted positions. It is commonly believed, however, that the unmodified full lateral position after induction of spinal anaesthesia might allow excessive spread of the block. We therefore compared baseline arterial pressures in the supine wedged, sitting, tilted and full lateral positions in 40 women who were about to undergo elective caesarean section. ⋯ Following spinal anaesthesia, hypotension (defined as a reading
