Effect of Perioperative iv Dexmedetomidine vs. Lidocaine on Postoperative Pain, Analgesic Consumption and Recovery After Abdominal Gynaecological Surgery

Postoperative pain continues to be inadequately managed and is the most common reason for the delay in discharge and unplanned hospital admission after surgery. Opioids remain the mainstay for postoperative analgesia. However, there is a continuous search for adjuvant therapies to reduce the doses of opioids and their related adverse effects, and extend the use of non-opioid analgesia for acute pain after abdominal surgery, thereby improving patient recovery. Currently there are no clinical trials that investigate the effect of intravenous lidocaine vs dexmedetomidine on postoperative pain, analgesic consumption and bowel function of patients undergoing abdominal gynaecological surgery. Purpose of this prospective double blind randomised clinical trial is the investigation of the effect of perioperative intravenous infusion of lidocaine vs dexmedetomidine vs placebo (Normal Saline 0,9%) on analgesic parameters and functional recovery of patients undergoing abdominal gynaecological surgery.
