TRANSVERSUS ABDOMINIS PLANE (TAP) BLOCK AS A MODALITY FOR POSTOPERATIVE ANALGESIA IN ABDOMINAL SURGERIES
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 43
Abstract
BACKGROUND Transversus Abdominis Plane (TAP) block is a regional analgesic technique which provides analgesia after abdominal surgery. There is a sensory blockade of abdominal wall skin and muscles via local anaesthetic deposition above transversus abdominis muscle. We evaluated the efficacy of the TAP block in the first 24 hours after abdominal surgery (Midline or non-midline) in a prospective, randomised controlled study. MATERIALS AND METHODS Sixty adult patients undergoing elective abdominal surgery under general anaesthesia were included in this study and were randomly assigned to TAP block group or control group. After induction of anaesthesia, unilateral or bilateral TAP block (depending upon site of incision) was performed using 20 mL of 0.5% Ropivacaine on each side. Intraoperatively, haemodynamic parameters like HR, SBP, DBP, MBP and SPO2 till the end of surgery. Postoperatively, patients were assessed for pain with VAS score for 24 hours at regular intervals by a blinded investigator. RESULTS TAP block significantly reduced the pain scores, requirement for rescue and demand analgesia in the unilateral and bilateral study groups. Postoperative VAS scores (both at rest and on coughing) in the TAP block group were significantly lower than those in the control group. The respiratory rate, intraoperative and postoperative pulse rate were also significantly lower in the TAP block group. CONCLUSION TAP block using 0.5% ropivacaine provided longer duration of analgesia than that in the control group in patients undergoing abdominal surgeries. TAP block via lumbar approach provides better pain relief especially in major lower abdominal surgeries as compared to upper abdominal surgeries. No complications attributable to TAP block or drug under study were detected.
