Brief Summary:
To relieve post laminectomy pain, we have tried intraoperative perineural injection of lidocaine right after the exposure in expecting that this would be preemptive analgesia by blocking the nerve transmission so that postoperative pain starts later and lighter.

Condition or disease Intervention/treatment Phase
Laminectomy Drug: Lidocaine, perineural injection, intraoperatively Drug: Lidocaine Phase 4

Detailed Description:

A randomized double-blind 40 patients aged 18-50 of ASA I and II undergoing laminectomy were included in the study. All the patients were followed for their heart rate, arterial pressure , respiratory rate, oxygen saturation, end tidal CO2 and postoperative VAS scores.

All the patients were premedicated with midazolam 0.1 mg/kg intramuscularly 40 minutes prior to surgery. The induction was made 2 mg/kg propofol, 1 ug/kg remifentanyl, 0.5mg/kg rocuronium. After the orotracheal intubation anesthesia was maintained with isoflurane (%0.5-2.0) and 0.1 mg/kg rocuronium.Just before the exposure of dorsal root, 0.5 cc %2 lidocaine was injected on the dorsal root.The patients postoperative analgesic period, VAS scores and additional analgesic need was recorded. For the postoperative analgesia tramadol 1 mg/kg tramadol was used.
