Applicable observation of butorphanol in painless colonoscopy examination

Abstract

Objective:To summarize the clinical effect of butorphanol compound propofol in painless colonoscopy examination and its feasibility.Methods:100 colonoscopy examination patients (56 males and 44 females aged from 19 to 60 years old) registered between August, 2016 and September, 2016 in the endoscopy center of our hospital were randomly selected. ASA classification is I or II level. Their body weight ranged from 55 kg to 75kg. They were randomly divided into two groups and each group included 50 cases. All patients went through conventional ambrosia and liquid fasting for 8 hours before the anesthesia and they drank magnesium sulfate liquid of 2500ml to clean their gastrointestinal tracts.After patients entered the operating room, their veins of upper limb were opened so as to monitor their HR, MAP and SPO2. After that, butorphanol of 20μg/kg was injected to patients of the experimental group while normal saline of the same amount of was injected to patients of the contrast group. After 60 seconds, propofol of 1~2 mg/kg was injected to both groups by the way of intravenous injection. The enteroscopy examination was started after patients had no eyelash reflection. Besides, actual application dose of propofol was adjusted according to clinical indications of patients and the adjusting frequency each time was controlled between 30 milligrams and 50 milligrams until the completion of the examination. SPSS 22.0 statistical software was used to analyze and handle research data of this group. Results:Anesthesia effect: The difference of inter-group comparison showed no statistical significance (P>0.05). The intra-group comparison and the inter-group comparison show that the difference in terms of changes of HR, MAP and SpO2 of patients in two groups before and after the anesthesia had no statistical significance (P>0.05).The awakening time, VAS score, postoperative vomiting times and the occurrence rate of respiratory depression of the observation group were all significantly lower than those of the contrast group (P<0.05).
