title: "Protective premedication": a comparative study of acetaminophen, gabapentin and combination of acetaminophen with gabapentin for post-operative analgesia.
abstract: BACKGROUND
  We carried out a study to evaluate the effects of protective premedication with Acetaminophen, Gabapentin and combination of Acetaminophen with Gabapentin on post-operative analgesia in patients undergoing open cholecys-tectomy under general anesthesia. PATIENTS #ENTITYSTARTX00026;
  
  
  METHODS
  The study was conducted in a double-blind randomized and controlled manner in 120 consenting patients of either sex belonging to ASA physical status grade I and II, between the age groups of 20 to 50 years, weighing between 40 to 65 kg and undergoing elective surgery (open cholecystectomy) under general anesthesia. The patients were divided into 4 groups: 1: placebo, 2: Acetaminophen 1000 mg, 3: 1200 mg Gabapentin, 4: Acetaminphen 1000 mg plus 1200 mg Gabapentin. The drugs were given two hours before induction. Time, number and total amount of rescue analgesic (tramadol) and VAS score at rest and on movement. Side effects like any episode of nausea/vomiting and level of sedation were noted.
  
  
  RESULTS
  Premedication with antihyperalgesic and analgesic agents helps to decrease postoperative pain scores. Gabapentin premedication is effective for providing better postoperative pain relief with lower and delayed requirements of rescue analgesics, but causes more episodes of nausea and vomiting and higher levels of sedation.
