Abstract
BACKGROUND: Lumbar spine surgery demands intense analgesia. Preemptive multimodal analgesia (MMA) is a novel approach to attenuate the stress response to surgical stimulus. AIMS: The aim of the study was to assess the intraoperative morphine consumption in patients undergoing lumbar spine surgery. PATIENTS AND METHODS: A randomized, prospective, double-blind study involving 42 patients belonging to the American Society of Anesthesiologists Class I and II scheduled to undergo elective lumbar spine surgery were allocated into two groups of 21 each. Group A (study group) received injection diclofenac sodium, paracetamol, clonidine, and skin infiltration with bupivacaine adrenaline and Group B (control group) received paracetamol and skin infiltration with saline adrenaline. Preemptive analgesia was practiced in both the groups. Intraoperative morphine consumption was documented. STATISTICAL METHODS: Intraoperative morphine consumption between the two groups was compared using Mann-Whitney U-test. Postextubation sedation score between the two groups was compared using Chi-square test and presented as number and percentage. P < 5% was considered statistically significant. RESULTS: Intraoperative morphine consumption was significantly low in the study group (P < 0.001). Postextubation sedation score was comparable between the two groups. CONCLUSION: Preemptive MMA has demonstrated significant morphine sparing effect intraoperatively in patients undergoing lumbar spine surgeries.
