ABSTRACT

OBJECTIVE:To observe clinical efficacy of specific 5-HT receptor antagonist granisetron combined with intravenous local anesthetic lidocaine pretreatment in minimizing propofol injection pain. METHODS:400 selective patients with laparoscopic cholecystectomy randomized into control group(group A),lidocaine group(group B),granisetron group(group C)and lidocaine combined with granisetron group(group D),n=100. Group A were treated with 3 mL normal saline and group B 20 mg lidocaine,group C 2 mg granisetron,group D 2 mg granisetron and 20 mg lidocaine. After 1 min the tourniquet released and a quarter of expected amount of propofol was given. Pain score of injection site was recorded. RESULTS:As group B、C and D,case number of injection nonpain in group A was higher than that of injection pain. There were statistical significance in the difference of case number and degree of injection pain among those groups(P
