Study Overview
Brief Summary
The goal of this study is to know how effectively TAP block can reduce postoperative pain in total abdominal hystrectomy patients when given ketamine in addition to bupivacaine in TAP block and to compare it with the conventional TAP block with bupivacaine only. The main question it aims to answer is:
Does intervention with ketamine in TAP block lowers the postoperative pain measured via visual analog scale and decreases the need for rescue analgesia?
Patients will be assessed for pain in PACU( post anesthesia care unit), 6 hours, 12 hours and 24 hours postoperatively. Time of rescue analgesia will also be noted if given.
Detailed Description
This is a prospective, randomized, double blind control trial.Patients will be randomly divided into 2 groups; group A and group B with 15 patients in each group. Group A will recive TAP block with 20ml solution of 0.25% bupivacaine on each side of abdomen while group B will recieve 50mg ketamine in addtion to 20ml of 0.25% bupivacaine.The drugs will be prepared by the second anesthesiologist who will not be part of data collection and analysis.Post operative pain will be assessed using VAS score in PACU, after 6 , 12 and 24hours post total abdominal hystrectomy. Inj. tramadol 50mg will be used as rescue analgesia.In addition to inj. pracetamol 1g 8 hourly and inj. ketorolac 30mg 12 hourly, time for administration of rescue analgesia will be noted.

Outcomes
Primary Outcomes
VAS score
Time Frame: At PACU(5 mins after shifting to PACU), 6,12 and 24 hours post-operatively
VAS (visual analog scale ) score noted VAS of \<2 = no pain VAS of 2-4 = mild pain VAS of 5-6 = moderate pain VAS of \>6 = severe pain
Time of receiving first rescue analgesia
Time Frame: within first 24 hours postoperatively
time for additional requirment of inj. tramadol 50mg for post operative pain relief
Secondary Outcomes
No secondary outcomes reported
