Ultrasound-guided erector Spinae plane block versus ilioinguinal/iliohypogastric block for postoperative analgesia in patients undergoing inguinal surgeries : A randomised clinical trial

This study is a randomised, parallel group, clinical trial comparing the effectiveness of two blocks i.e ultrasound guided Erector Spinae plane block versus ilioinguinal/ iliohypogastric block for postoperative analgesia in patients undergoing inguinal surgeries, as measured by duration of analgesia and pain score in 24 hours following surgery. The primary outcome of the study is to record the severity of pain using Numerical rating scale and time to request of first analgesia i.e the time elapsed between the end of surgery to 1st dose of analgesia. The secondary outcome is to see the total no. of analgesic doses of opioids and NSAIDs in 24 hours following surgery and to see any side effects like nausea, vomiting and shivering occurring after the procedure.
