Overview
Brief Summary
Randomized double blind placebo controlled trial on transversus abdominus plane block approached from abdominal cavity, in patients undergoing total abdominal hysterectomy.
Detailed Description
Potential advantages compared to percutaneous approach are decrease in risk of visceral injury as it is under direct visual and tactile guidance, ease of approach in obese patients, short theatre time for administration, easy to administer.

Outcomes
Primary Outcomes
postoperative 24hr morphine consumption
Time Frame: 24 hours
The primary objective of this study is to demonstrate the effectiveness of tranversus abdominis plane block using the intraabdominal approach in reducing postoperative 24 hours morphine consumption after total abdominal hysterectomy (TAH) where time 0 is taken as time of arrival at PACU.
Secondary Outcomes
- morphine consumption on arrival to post-anaesthetic care unit(PACU) and 4, 12 and 24 hours after.(24hrs)
- Degree on pain according to numerical pain score on arrival to post-anaesthetic care unit(PACU) and 4, 12 and 24 hours after during rest and movement (cough(24hrs)
- incidence of nausea and vomiting(24hours postoperatively)
