Abstract :

Background:The ideal local anaesthetic solution for intrathecal use has rapid onset and and reliable duration,with less incidence of the side effects.This study was aiming to compare the onset of anaestesia and duration of action of isobaric and hyperbaric bupivacain for subarachnoid block. Method:Hundred patients undergoing lower abdominal surgeries were allocated into two groups. Group I received 0.5% isobaric bupivacain 4cc and Group II received 0.5% hyperbaric bupivacain 4cc.Injection was made intrathecally in midline position at L3–L4 interspace in sitting position. Statistical analysis: Mean and S.D. calculated and Z test applied for the clinical significance. Results:Onset of analgesia was faster i.e.T10 level achieved with hyperbaric bupivacain as compared to isobaric bupivacain.But duration of block longer with the isobaric bupivacain as compared to hyperbaric solution.In both groups haemadynamic changes were not significant.
