Transient Lumbar Pain after 5% Hyperbaric Lignocaine Spinal Anaesthesia in Patients Having Minor Vascular Surgery

Abstract

Transient lumbar pain has been reported to occur frequently in patients having surgery using 5% hyperbaric lignocaine for spinal anaesthesia. The incidence of transient lumbar pain is highest with this agent in patients having surgery in the lithotomy position and in outpatients. The aim of this audit was to determine the incidence of transient lumbar pain in patients having minor surgery for the complications of peripheral vascular disease, a group of patients in whom short duration spinal anaesthesia is desirable. One hundred patients were audited prospectively. All patients had 5% hyperbaric lignocaine spinal anaesthesia and were followed up postoperatively utilizing a standardized questionnaire to determine the incidence of transient lumbar pain. The condition was found to occur in 4% of patients. This low incidence of transient lumbar pain justifies the continued use of 5% hyperbaric lignocaine for spinal anaesthesia in this group of patients.
