TO COMPARE THE EFFICACY OF ANALGESIA PRODUCED BY THE ADDITION OF FENTANYL TO1%2- CHLOROPROCAINE VERSUS 0.5% ROPIVACAINE IN SPINAL ANAESTHESIA FOR AMBULATORY SURGERIES - RANDOMIZED DOUBLE-BLINDED CONTROLLED STUDY.

Abstract

Introduction: Short surgical procedures warrant the use of a lower dose of local anaesthetics. We compare the combination of 2-chloroprocaine (CP) + fentanyl and ropivacaine+ fentanyl spinally for early micturition and ambulation. Our aim was to assess the duration of the motor blockade. As CP has a shorter half-life it would show a signicantly shorter block regression time. Randomized double-blinded study involving 82 patients posted for short-duration s Methodology: urgeries (<90 mins) was carried out. Randomization was done using the chit method, 41 chits each with C and R written on it, for ropivacaine and 2-CP were used: Group C - 1%2- CP (30mg) with 12.5mcg fentanyl and Group R - 0.5% Ropivacaine (15mg) with 12.5mcg fentanyl. The assessor and patient were blinded. Onset, time of regression and duration of sensory and motor blockade, intraoperative haemodynamic parameters, time of rst rescue analgesia, time of micturition and time of ambulation was assessed. – c Statistical analysis hi-square test, independent t-test, p-value <0.05 Result: CP shows a faster recovery of early ambulation and micturition, without side effects. Fentanyl improves duration without interfering in micturition/ambulation CP provides adequate duration and depth of surgical anaesthe Conclusion: sia for the short procedure with faster block regression and early ambulation compared to ropivacaine. The addition of fentanyl improves the quality of the block without interfering with the postoperative outcomes.
