Background: Severe post-operative pain following spine surgery is a significant cause of morbidity, extended length of stay and marked opioid usage.The objective of this research was to compare the efficacy of bilateral USG guided erector spinae plane block (ESPB) on postoperative pain using visual analogue score (VAS) at 0 and 4 hours in lumbar spine surgeries.
Materials and Method: Eighty patients of age group 18-70 yrs of ASA physical status I & II of both genders undergoing lumbar spine surgery were randomly allocated in two groups. In Group '1' (n=40) patients received bilateral USG guided ESPB using 20 ml of study solution i.e. 0.2% ropivacaine each side after induction of General Anaesthesia (GA). In Group '2' (n=40) patients received bilateral USG guided ESPB using 20 ml normal saline each side after induction of general anaesthesia. In both groups postoperative VAS scores at various intervals (0,4,6,8,12, and 24 hours), the timing of the first dose of rescue analgesia, and the total postoperative analgesic requirements within 24 hours between two groups was measured. Additionally intraoperative hemodynamics (SBP, DBP, HR) and the incidence of postoperative nausea and vomiting in both groups was also compared.
