Metoclopramide 와 Lidocaine 전투여가 Propofol 정주 시 발생되는 혈관통에 미치는 영향

Baekground : Propofal has a high incidence of pain with intravenous injection, and different methods have been used to minimize the incidence and severity of this pain. In this study, we have compared the effect of lidocaine pretreatment with that of metpclopramide pretreatment on propofol injection pain. Methods : Ninety healthy female patients scheduled for general anesthesia were randomly divided into three groups; saline group (n = 30), lidocaine group (n = 30) and metoclopramide groups (n =30). Each patient received 2 ml of pretreatment solution (normal saline, 1% lidocaine, 0.5% metoclopra- mide) via 18 G angiocatheter inserted in the antecabital fossa after applying an arm tourniquet inflated to 50 mmHg, The toumiquet was released 1 minute later, followed by intravenous injection of 2.5 mg/kg of propofol. The assesement of pain was made at the induction of anesthesia and in the recovery room and the severity of pain was classified as none, mild, moderate, severe by one observer. Results : The severity and incidence of pain diminished significantly in the lidocaine group and the metoclopramide group compared with the saline group at the induction of anesthesia (P < 0.05) and there was no significant difference between the lidocaine group and metoclopramide group. We had similar results in the recovery room and one patient from the saline group and the metoclopramide group had no recaII regarding injection pain. Conclusions : lnttavenous metoclopramide pretreatment is as effective as intravenous lidocaine pretreatment in alleviating the propofol injection pain. (Korean J Anesthesiol 2000; 39: 14~18)
