TAP Block
Patients in this arm will receive ultrasound guided TAP bock with Bupivacaine 0.25% 20ml per side or to a maximum 1mg/kg per side and the skin puncture will be covered with a small plaster Ultrasound guided Transversus Abdominis Plane (TAP) bock: Ultrasound guided TAP bock with Bupivacaine 0.25% 20ml per side or to a maximum 1mg/kg per side and the skin puncture will be covered with a small plaster
Local Anaesthetic Infiltration
Laparoscopic port sites and specimen extraction site will be infiltrated with a total of 40 mls 0.25% bupivacaine subcutaneously at the end of the procedure in the control group and plasters will be stuck on either side approximately where a skin puncture for tap block would be made. Local anaesthetic infiltration of laparoscopic port sites: Laparoscopic port sites and specimen extraction site will be infiltrated with a total of 40 mls 0.25% bupivacaine subcutaneously at the end of the procedure in the control group and plasters will be stuck on either side approximately where a skin puncture for tap block would be made.
