Analgesic Efficacy of Intravenous Lidocaine and/or Ketamine

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01439399
Recruitment Status : Completed
First Posted : September 23, 2011
Last Update Posted : September 23, 2011

Joray Florence, University of Lausanne Hospitals

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.

Condition or disease Intervention/treatment Phase
Postoperative Pain Drug: Lidocaine, Drug: Ketamine Drug: association ketamine-lidocaine Drug: Placebo Not Applicable

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.

Arm Intervention/treatment
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.

Primary Outcome Measures :

  2. Mechanical hyperalgesia [ Time Frame: 48 hours ]
    Mechanical hyperalgesia using pressure algometry

  3. Occurrence of side effects [ Time Frame: 48 hours ]
    Occurrence of side effects: sedation, nausea, vomiting, itching, nightmares
