Description
Summary:Use of spinal anaesthesia is gradually increasing in ambulatory setting. With the continuing controversy over the use of lidocaine for spinal anaesthesia, other local anaesthetics are being explored to achieve reliable spinal anaesthesia with rapid recovery and minimal side-effects. This study explored the use of long acting local anaesthetic bupivacaine in ambulatory setting. One hundred patients presenting for endoscopic uro-gynaecological surgeries were randomized to four groups according to dose of bupivacaine they received keeping the volume constant. Maximum level of sensory block, intensity of block, time to two segment regression, time to S2 regression and time to discharge were recorded. Results of our study indicate that spinal anaesthe-sia with 7.5 mg of 0.5% bupivacaine in 8% dextrose diluted with equal volume of saline provides an optimal combination of adequate anaesthesia with recovery profile acceptable for ambulatory endoscopic uro-gynaecological surgeries.
