Clinical Trial Summary

This study is conducted to determine whether morphine added to bupivacaine in ultrasound guided (USG) transversus abdominis plane (TAP) block has beneficial effects than bupivacaine alone in providing postoperative analgesia for inguinal hernia surgery.

Description:

Total of forty adult patients of American Society of Anaesthesiologists (ASA) physical status ( PS) I - II scheduled for elective inguinal hernia surgery under spinal anaesthesia were recruited in this study after getting written informed consent. They were randomized to undergo ipsilateral USG TAP block with 20 ml of 0.25 % bupivacaine (group B) versus 20 ml of 0.25 % bupivacaine with 3 mg morphine (group BM). Patients were followed postoperatively for the 24 hours by a blinded investigator for monitoring of number of rescue analgesic consumed, duration of analgesia, numerical rating scale (NRS) at rest and on cough and any adverse effects.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	• Duration of postoperative analgesia • Postoperative analgesic requirement	Time from TAP block to first request of analgesic is considered as duration of analgesia Less requirement of rescue analgesic is considered as better	Till 24 hour after surgery
Secondary	• NRS for pain at rest and on cough between the groups • Any side effects	Group with higher NRS score is considered a less effective Group with increase side effects is considered as not acceptable	Till 24 hour after surgery
