Abstract
Objectives: The aim of the study was to compare the intraoperative hemodynamics and post-operative analgesia after using bilateral erector spinae block (ESB) and conventional techniques during spinal surgeries. The study also aims at comparison of analgesics consumption in patients during post-operative period. Methods: One hundred adults aged 18–80 years with American Society of Anaesthesiology physical status I/II scheduled for elective lumbar spine surgeries (two levels) under general anesthesia (GA) were divided into two groups. Group A received erector spinae plane block (ESPB) along with GA and Group B received GA only. Injection Paracetamol 1 g intravenously was given as rescue analgesia. Intraoperative hemodynamics, visual analog score at rest and at movement in 24 h postoperatively, first rescue analgesia, total dose of analgesics in first 24 h postoperatively, and intraoperative opioid dose requirement were compared in both the groups for 7 days. Results: Intraoperative hemodynamics in ESPB group were found to be more stable than the control group. There was a significant low VAS score in Group A compare to Group B at rest and on movement (p<0.001). The time for first rescue analgesia was prolonged in group ESPB as compared to control group (p<0.05). The total dose of analgesia required in first 24 h was significantly lower in patients of ESP group 25±41.96 mg 82.5 than patients in control group ±22.73 mg. Conclusion: Ultrasound-guided bilateral ESB provides profound intraoperative hemodynamic stability with perioperative analgesia in comparison to conventional GA technique. The present study concluded that ESP block decreased the opioid requirement in both intraoperative and post-operative period.
