Gastrointestinal endoscopy in elderly patients over 70 with conscious anesthesia / 中华消化内镜杂志

ABSTRACT

Objective To evaluate the safety of conscious venous anesthesia with fentanyl and propofol in elderly patients over 70 during gastrointestinal endoscopy. Methods Clinical data of 826 elderly patients over 70, who underwent gastrointestinal endoscopy with venous anesthesia, were retrospectively analyzed. The patients were divided into 2 groups according to their ages, with 618 patients aging from 70 to 80 in group A, in which 342 received endoscopy and 276 underwent colonoscopy, and 208 patients older than 80 in group B, in which 112 underwent endoscopy and 96 had colonoscopy. Another cohort of 600 patients younger than 70, who underwent venous anesthetic endoscopy during the same time period, was randomly selected as the control group, in which 400 patients received endoscopy and 200 had colonoscopy. Blood pressure, heart rate, peripheral oxygen saturation (SpO2) and adverse reaction were monitored in each patient during the procedure and compared among different groups. Results No procedure-related perforation or sedation-related mortality was observed, and no procedure was terminated clue to sedation complication. The average dosages of propofol used in procedure of endoscopy in groups A, B and control were 54.22±21.36 mg, 40.22±12.46 mg, and 86.44±34.26 mg, respectively. The average dosages of propofol in colonoscopy were 82.56±40.64 mg, 45.36±15.44 mg and 102.23±46.32 mg, respectively. With same procedure, there was no significant difference in heart rate and blood pressure among different groups, nor was there any difference in these variables before and after the procedure in each group (P>0.05). Sedation exerted more influence on SpO<,2> in elderly patients. A total of 18 cases in groups A and B experienced SpO<,2> <90%, which was mainly due to aspiration of saliva and relieved by oxygen inhalation. Conclusion Under appropriate monitor, it is safe and feasible to give conscious sedation to elderly patients over 70 during gastroimestinal endoscopy.
