Scientific title
Study objectivesA considerable number of patients require opioids during recovery after laparoscopic sterilization. This implies nausea, dizziness and sedation and this increases the number of unplanned admissions. Gabapentin has shown excellent postoperative analgesic effects in a number of recent studies showing few side effects. This study was designed to test whether gabapentin given preoperatively can reduce the number of patients needing morphine in the recovery period.
Ethics approval(s)Approved by the Regional Ethics Committee of Copenhagen County on 15/04/2002; reference number: KA 02028s
Health condition(s) or problem(s) studiedPost operative pain after laparoscopic sterilization
InterventionFemales scheduled for laparoscopic sterilization using Filshie clips were randomised into two treatment groups (gaba group and control group).

All patients received lornoxicam 8 mg by oral administration (p.o.) for 30 min before the procedure. Patients in the gaba group received gabapentin 1,200 mg p.o. and patients in the control group received placebo capsules prior to the procedure.

All patients were anesthetized according to a protocol, using remifentanil and propofol. Postoperative analgesia was obtained with patient-controlled infusion of morphine. Pain, nausea, dizziness and sedation were scored at two and four hours after end of anesthesia.
