ABSTRACT
The relative merits of right and left lateral tilt were assessed in 75 parturients at elective caesarean section. Significant maternal hypotension (aortocaval occlusion) occurred more frequently with rightward tilt (left hip supported). The clinical and biochemical status of the fetus was generally more favourable with left lateral tilt, as were the maternal-to-fetal blood gas gradients and relationships. The routine use of left lateral tilt is advocated.

In 60 mothers with normal placental function, the relative merits of right and left lateral tilt during Caesarean section were assessed. Maternal-foetal biochemical values and relationships were generally more satisfactory with the left lateral position. The incidence of hypotension (revealed aorto-caval occlusion) before and after induction of anaesthesia, was significantly greater (P less than 0.001) with the "right side down" posture.

Four cases of prolonged block following epidural anaesthesia in obstetric patients are described. Recovery was complete in all cases. The possible causes are discussed.
