Abstract:
Background: Major lumbar spine surgeries cause severe postoperative pain. The aim of this randomized controlled study is to compare analgesic efficacy of dexmedetomidine to dexamethasone as an adjuvant to ropivacaine in erector spinae plane block for lumbar spine surgeries.
Materials and Methods: A total of 60 patients, categorized into ASA grading I, II and III were randomly allocated into Group A and Group B of 30 each. Group a received 30 ml drug (28 ml of 0.2% Ropivacaine + 1mcg/kg dexmdetomidine diluted to 2 ml). Group B received 30 ml drug (28 ml of 0.2% Ropivacaine + 8mg of dexamethasone 2 ml).
Results: The study revealed intra operative analgesic requirement and mean pain score was significantly less in dexmedetomidine compared to dexamethasone (113.67 vs 131.67 mcg: p<0.01). Mean time requirement of first analgesia was significantly longer in dexmedetomidine group (8.27 hrs vs 6.67 hrs; p<0.01) and mean time for ambulation was significantly shorter in cases of dexmedetomidine group (1.8 vs 2.94 days; p<0.01). No significant difference with regard to age, sex, weight, ASA grade between the two groups. Duration of surgery, mean pulse rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure and SPO2 were comparable between two groups.
Conclusion: Addition of Dexmedetomidine to Ropivacaine in an erector spinae block for lumbar spine surgeries leads to a reduction in total opioid consumption, need for rescue analgesia, a shorter postoperative recovery time and a quicker time for mobilization compared to Dexamethasone.
