Cerebral Tumor Clinical Trial
Official title:
The Effects of Gabapentin Premedication on Postoperative Pain,Nausea,Vomiting and Sedation in Patients Undergoing Neurosurgery
The study is to observe the effects of gabapentin premedication on postoperative pain,vomiting and nausea in patients undergoing neurosurgery. 100 neurosurgical patients are randomized into groups gabapentin(GG) or placebo(GP). Patients are given gabapentin or placebo orally the night before operation day and 2hours before surgery,respectively.The investigators hypothesized that lower incidence of postoperative pain,vomiting and nausea be observed in GG than GP.
This is a random, double-blind study. In GG, patients are given gabapentin 600mg orally at the night and 2hours before surgery, respectively. In PG, vitamine pills are given instead.Total intravenous anesthesia is applied for all patients. 1hour, 2hours,1day, 2days, 3months and 6months after surgery, patients are evaluated for pain (VAS) and incidence of PONV. In addition,Glasgow Score, Ramsay Score and other gabapentin-related effects, such as somnolence,dizzy or dry mouth are also observed.The incidence of persistent pain and neuropathic pain was assessed at the 3-mo and 6-mo postoperative evaluation. ;
