Abstract

Background: To compare the clinical effects of 3ml of intrathecal hyperbaric ropivacaine 0.5% (2ml of 0.75% plain ropivacaine and 1ml of 25%dextrose)  with 3ml of 0.5% plain ropivacaine (2ml of 0.75% plain ropivacaine and 1ml of 0.9% normal saline) for spinal anaesthesia in minor gynaecological and urological surgeries. Subjects and Methods: 60 patients belonging to ASA physical status I & II scheduled for minor gynaecological and urological surgeries under spinal anaesthesia were randomly selected for the study and are divided into two groups of 30 each. Group H patients received 3 ml of intrathecal hyperbaric   ropivacaine 0.5% (2 ml of 0.75% plain ropivacaine and 1 ml of 25% dextrose). Group P patients received 3 ml of plain ropivacaine 0.5% (2 ml of 0.75% plain ropivacaine and 1 ml of 0.9% saline). Results: There was significant difference between the two groups in mean time to onset of sensory block at T10, 257.5 ± 23.03 sec with group H and 478.0 ± 16.48 sec with group P, (P<0.0001). Total duration of sensory block was 201.7 ± 8.64 min in group H and 261.17 ± 8.27 min in group P, which is significant (P<0.0001).Mean time of onset of motor block was 355.50 ± 16.83 sec in group H and 568.33 ± 2.76 sec in group P, which is significant (P<0.0001). Duration of motor block was 127.33 ± 6.53 min in group H and 168.83 ±  8.27  min in group P which is clinically and statistically significant (P<0.0001). Hemodynamic parameters were comparable in both groups. Conclusion: Addition of glucose to plain ropivacaine   increases the speed of onset of both sensory and motor block, and also increases the speed of recovery from sensory and motor block in minor gynaecological and urological surgeries. Plain solutions are less reliable for surgery above a dermatomal level of T10.
