Arms Assigned Interventions
Active Comparator: Lidocaine
Intravenous lidocaine administered preoperatively (anesthesia induction) and postoperatively during 48 hours
Drug: Lidocaine,
Lidocaine group received an IV bolus of 1.5 followed by a continuous infusion of 2 intraoperative and 1.33 for 48 h postoperative.
Active Comparator: Ketamine
Intravenous ketamine administered preoperatively (anesthesia induction) and postoperatively during 48 hours
Drug: Ketamine
Ketamine group received a bolus of 0.5, then 0.25 followed by 0.1 for the first 24 h, then 0.05 for the next 24 h.
Active Comparator: Ketamine-Lidocaine
Intravenous association of ketamine and lidocaine administered preoperatively (at anesthesia induction) and postoperatively during 48 hours.
Drug: association ketamine-lidocaine
Ketamine-lidocaine group received a bolus of 1.5 of lidocaine and 0.5 of ketamine, a continuous infusion of 1.3 of lidocaine and 0.17 of ketamine was delivered followed by 0.9 of lidocaine with 0.08 of ketamine during 48 h, the dose of ketamine being reduced to 0.04 after the first 24 hours.
Placebo Comparator: Saline 0,9%
Control group
Drug: Placebo
The control group (C) received an equal volume of saline 0.9 % during 48 h.

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.
