PERBANDINGAN DAYA GUNA KETAMIN 0,2 MG/KGBB DAN LIDOKAIN 2 ML 1% INTRAVENA UNTUK MENCEGAH NYERI PADA PENYUNTIKAN PROPOFOL INTRAVENA

Propofol has been used widely for anesthetic induction and maintenance purposes, however propofol has unpleasant effect which could produce pain in injection site either post-induction hypotension. Some methodes have been used in order to reduce this pain as the velocity of injection, either addition of lidocain and ketamin. Ketamin could milting pain incidence in propofol injection. This research aimed on comparing administration of 0,2 mg for each kilo body weight Ketamin and 2 ml 1 % Lidocain in order to reduce post propofol injection pain. Randomized Controlled Trial (RCT) with double blinded methode have been used in this research. This research underwent in 134 patients, age ranged beetween 18-50 years old, American Society of Anaesthesiologists (ASA) I and II physical status labelled patients who�s planned to elective operation in the manner of general anaesthesia in Dr. Sardjito Hospital, Yogyakarta. The subjects divided into two groups, Group A belonged to patients who have given to them 2 mg for each kilo body weight Ketamin while 2 ml 1 % Lidocain have been given for Group B. All of these patients applied with 18 G needle radialis vein intra venous cathetherization. For both of the groups, the drugs have been giving via intra venous which previously dammed by 50 mmhg pressure. After one of the drug has injected, the pressure maintained for 60 seconds and soon after the torniquet has deflated, propofol then injected. Pain measurement due to propofol injection is done based on pain scoring, with 0-3 scales. Then, anesthetic maintenance prooced as planned. This research resulted on there was significant differentiation (p
