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.
Official title: Intraoperative Perineural Injection of Lidocaine for Postlaminectomy Pain
Study design: Prevention, Randomized, Double Blind (Subject, Investigator, Outcomes Assessor), Placebo Control, Parallel Assignment, Efficacy Study
Primary outcome: In the laminectomy operation, right after the exposure of the dorsal root , an injection of lidocaine attenuates postoperative pain.
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.
