A Prospective double-blinded randomized clinical trial to test the effect of transversus abdominis plane block on postoperative pain and opoid consumption after abdominal hysterectomy.
Two groups of each 24 patients. All patients are given general anesthesia. The patients are randomized to have a ultrasound guided bilateral transversus abdominis plane block with either 2 x 20 ml 0,75 % ropivacaine or 2 x 20 ml of 0,9 saline. All patients are provided with a PCA for self administration of morphine.
Pain score on visual analog scale, nausea and vomiting are monitored at 1, 2, 4, 6, 8 and 24 hours postoperatively as well as the total consumption of morphine after 24 hours.
