Abstract：Objective To study the feasibility, safety and adverse reactions of painless endoscopy performing on the Tibet plateau.Methods Eight hundreds and ten patients who had received painless endoscopy in Tibet Corps Hospital of PAP between July 2015 and June 2016 were enrolled in the experiment group (painless group), while another 810 patients who had received conventional endoscopy in the same period were enrolled randomly in the control group (conventional group).The changes of blood pressure(BP), heart rate(HR), respiration rate (RR), blood Oxygen saturation (SpO2) before, in the middle of and after the painless endoscopy inspection were observed. The endoscopic completion rate, degree of comfort, satisfaction with the operation, acceptability of the endoscopic examination, the operators’ degree of satisfaction with the endoscopic vision and gastrointestinal movements, and the adverse reactions were recorded and compared between the two groups.Results SpO2 in the middle of endoscopic inspection was decreased by 8.2 percent compared with that before the inspection in painless group, and the difference was of statistical significance (P<0.05). However, the decline of SpO2 was transient so that the postoperative SpO2 could return to the preoperative level after corresponding treatment. All the patients in painless group finished the examination. There were twelve cases of transient respiratory depression and two cases of cough due to adverse reactions in painless group. 805 patients in control group finished the examination. There were 426 cases of nausea and vomiting out of adverse reactions in control group. The completion rate of endoscopy, degree of comfort, satisfaction with the operation, acceptability of the endoscopic examination, the operators’ degree of satisfaction with the endoscopic vision and gastrointestinal movements in painless group were higher than in control group, and there were statistically significant differences (P<0.05) between the two groups.Conclusions The application of painless endoscopy on the Tibet plateau is feasible and safe. The patients feel comfortable and satisfied. The endoscopic vision is better. Painless endoscopy is worthy of clinical popularization on the plateau, but attention should be paid to the adverse reaction of transient respiratory depression.
