ABSTRACT

Objective To discuss the feasibility and safety of propofol used in senile patients undergoing minor surgery including gastroscopy and colonoscopy.Methods 40 patients aged 80-88 years old were randomly divided into two groups with 20 cases for each group.Group P received only propofol by intravenous injection in a speed of 1ml/s till eyelash response disappeared.In patients of group F fentanyl was first given at 0.5?g/kg,and 1 minute later,the patients were given propofol by intravenous injection in a same speed as in group P if there was no discomfort until eyelash response disappeared.MAP,HR,SpO2 and RR were determined before induction of anesthesia,beginning of operation,and 1st,3rd and 5th minute after operation.The onset time of anesthesia,total dosage of propofol used,time of palinesthesia and follow-up results were recorded.Results MAP was significantly decreased in both groups at the beginning of operation,and more stable in group F at the 3rd and 5th minute after operation.There were significant differences between two groups in amount of propofol used,and the dosage in group F was less than that used in group P(P
