Summary: | In this observational study, an alfentanil-containing patient controlled analgesia device was evaluated for the relief of visceral pain during elective caesarean section under subarachnoid anaesthesia. Forty healthy women at term received 2.5
mL of intrathecal hyperbaric 0.5% bupivacaine in the sitting position. Surgery began when loss of cold appreciation to the fourth thoracic dermatome was demonstrated. The patient controlled analgesia device was configured to deliver

of alfentanil when first actuated. Each subsequent demand delivered

with a 2-min lock-out interval. Sixty-five percent of women used alfentanil during surgery. The median (IQR) consumption of alfentanil was 360 (278–720)
μg. Patient controlled analgesia is a useful method of supplementing subarachnoid anaesthesia for caesarean section. The technique is simple to use and in this group there were no troublesome side effects. |
