Effect of Adding Dexmedetomidine to Ropivacaine for Transversus Abdominis Plane Block: A Prospective Randomised Controlled Trial
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 2
Abstract
We conducted this trial to study the effects of adding dexmedetomidine to ropivacaine for transversus abdominis plane (TAP) block. Sixty patients scheduled to undergo elective hernia repair with spinal anaesthesia as primary anaesthetic technique were divided into 2 groups. Group R (n=30) received 20 ml of 0.5% ropivacaine and 2 ml normal saline while Group RD (n=30) received additional 0.5µg/kg dexmedetomidine. Group RD had significantly less postoperative visual analogue score, longer duration of analgesia and needed less analgesics. We conclude that adding dexmedetomidine to ropivacaine for TAP block improves the duration of postoperative analgesia and reduces the postoperative pain and analgesic requirements when compared to ropivacaine alone. However, more studies are needed to study the side effects of dexmedetomidine when used as an adjuvant drug in TAP block.
