COMPARATIVE EVALUATION OF 0.5% ROPIVACAINE AND 0.5% BUPIVACAINE IN COMBINED FEMORAL AND LATERAL FEMORAL CUTANEOUS NERVE BLOCK FOR POST OPERATIVE ANALGESIA IN KNEE AND ABOVE KNEE ORTHOPAEDIC SURGERIES UNDER SPINAL ANAESTHESIA
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2019, Vol 8, Issue 6
Abstract
BACKGROUND Femoral Nerve Block (FNB) and Lateral Femoral Cutaneous Nerve Block (LFCNB) are easy to perform, have high success rates, have fewer complications and have significant clinical applicability for post-operative pain management in surgeries on the anterior thigh, knee and quadriceps tendon repair. We compared the efficacy of 0.5% Ropivacaine and 0.5% Bupivacaine in combined femoral and lateral femoral cutaneous nerve block on the duration of postoperative analgesia in knee and above knee surgeries. MATERIALS AND METHODS 90 patients of ASA grade I and II who underwent knee and above knee surgeries of lower limb were included in this study. These patients were divided in to three groups (n=30 each) according to the study drugs. Group N (Normal Saline), Group R (0.5% Ropivacaine), and Group B (0.5% Bupivacaine). Each patient received a fixed volume of study drugs: 15 ml for FNB and 8 ml for LFCNB. The patients were observed for Time of Onset of Analgesia (TOA), Duration of Analgesia (DOA), Assessment of Severity and Time of Post-Operative Pain. RESULTS Onset of action was faster with Ropivacaine as compared to Bupivacaine (p=0.001) (Group R<B<N). Duration of analgesia was longer (Group R>B>N) in Ropivacaine group than Bupivacaine (p=0.001). VAS>3 was observed at 7.13 ± 1.01 hrs., 15.06 ± 1.72 hrs. and 11.33 ± 1.52 hrs. in group N, R and B respectively (p<0.05). CONCLUSION Combined Femoral Nerve Block and Lateral Femoral Cutaneous Nerve Block with Ropivacaine provides early onset, prolonged duration and better relief in post-operative pain with minimal adverse effects as compared to Bupivacaine in knee and above knee surgeries.
