The Comparison Of Clinical Effects On Intravenous Anesthesia With Remifentanil Or Fentanyl Combined With Propofol In The Thoracic Operation

Objective To evaluate clinical effects on intravenous anesthesiawith remifentanil or fentanyl combined with propofol in the thoracicoperation in a randomized controlled study. Methods: Fortyambulatory adult ASA physical status I and II patients scheduled forthoracic operation were randomized divided into to groups. Their ageswere between 40~77.Group R were received remifentanil ,and group Freceived fentanyl ,both through TCI. In both groups anesthesia wasstarted by atropine 0.01mg/kg half hour before operation, induced byremifentanil or fentanyl 2.5μg/kg combined with propofol 1~2mg/kgwithin 30s , and maintained with remifentanil 0.2μg/kg or fentanyl0.03μg/kg combined with propofol 100~150μg/kg per min andvecuronium 0.06mg/kg intermittently. Intubation was facilitated withvecuronium 0.08~0.12mg/kg. And the patients were mechanicallyventilated (Vt 8~10ml/kg,RR10~13 bpm).The variables recorderswere age ,sex, weight, changes of hemodynamics, of drugs and timearound the operation and side effects after operation Result: The...
