5. Study Description
Brief Summary
The aim of the present study is to evaluate the analgesic benefit of intravenous lidocaine and ketamine in the perioperative period of abdominal surgery.
Detailed Description
Optimal postoperative pain management facilitates rehabilitation immediately after abdominal surgery. Multiple studies have demonstrated that successful postoperative analgesia also reduces perioperative complications and improves patient comfort, thereby providing many benefits for the patient. In acute postoperative pain management intravenous lidocaine and/or ketamine have been advocated because of their morphine-sparing effect.
