Abstract

Aims: This study is to observe the effect of barbotage on sensory spread during subarachnoid block with 0.5% of Heavy Racemic mixture Bupivacaine. Methods and Material: 50 ASA grade 1 and 2, were randomised to receive 3cc of 0.5% heavy Bupivacaine into subarachnoid space at L3-L4 space with patient in right lateral position using 25 gauze quincke’s spinal needle (25 patients with barbotage/25 patients without barbotage). Primary objective of the study included the highest level of analgesia using pin prick, the time taken to achieve the highest level of sensory block and time taken for modified bromage scale 3 motor block. Secondary objective included hemodynamic parameters and the usage of vasopressor. Statistical Analysis used: Mean, Standard Deviation, Student ’t’ test, P Value. Results: The highest level of analgesia obtained was similar in both group (mean T5 Dermatome).The time to reach the highest dermatome (9.65 minutes vs. 4.88 minutes with P value <0.001), the modified bromage scale 3 level motor blockade (7.47 minutes vs. 3.35 minutes with P value< 0.001) and the two segment regression of analgesia was faster in barbotage group (65.94 minutes vs. 53.82 minutes with P value <0.001). Conclusions: In this study, the quality of analgesia was similar in both groups. There was no incidence of uncontrolled cephalad spread in barbotage group.
