Abstract

Purpose of review: The present review evaluates the evidence available in the literature to see whether low-dose spinal anaesthesia for Caesarean section is effective in preventing maternal hypotension while at the same time guaranteeing effective anaesthetic conditions.

Main findings: From prospective trials, it is clear that lowering the spinal dose improves maternal haemodynamic stability. Doses of intrathecal bupivacaine between 5 and 7 mg are sufficient to provide effective anaesthesia. Complete motor block is, however, seldom achieved and adequate anaesthesia is limited in time.

Summary: Low-dose spinal anaesthesia as part of a combined spinal–epidural technique is a valuable method in improving maternal and fetal outcome during anaesthesia for operative delivery.
