| 7 | One year experience with computer-assisted propofol sedation for colonoscopy显示文摘AIM To report our one-year experience with computer assisted propofol sedation(CAPS) for colonoscopy as the first United States Medical Center to adopt CAPS technology for routine clinical use.METHODS Between September 2014 and August 2015, 2677 patients underwent elective outpatient colonoscopy with CAPS at our center. All colonoscopies were performed by 1 of 17 gastroenterologists certified in the use of the CAPS system, with the assistance of a specially trained nurse. Procedural success rates, polyp detection rates, procedure times and recovery times were recorded and compared against corresponding historical measuresfrom 2286 colonoscopies done with midazolam and fentanyl from September 2013 to August 2014. Adverse events in the CAPS group were recorded.RESULTS The mean age of the CAPS cohort was 59.9 years(48.7% male); 31.3% were ASA?Ⅰ, 67.3% ASA Ⅱ and 1.4% ASA Ⅲ. 45.1% of the colonoscopies were for screening, 31.5% for surveillance, and 23.4% for symptoms. The mean propofol dose administered was 250.7 mg(range 16-1470 mg), with a mean fentanyl dose of 34.1 mcg(0-100 mcg). The colonoscopy completion and polyp detection rates were similar to that of historical measures. Recovery times were markedly shorter(31 min vs 45.6 min, P < 0.001). In CAPS patients, there were 20(0.7%) cases of mild desaturation(< 90%) treated with a chin lift and reduction or temporary discontinuation of the propofol infusion, 21(0.8%) cases of asymptomatic hypotension(< 90 systolic blood pressure) treated with a reduction in the propofol rate, 4(0.1%) cases of marked agitation or discomfort due to undersedation, and 2 cases of pronounced transient desaturation requiring brief(< 1 min) mask ventilation. There were no sedation-related serious adverse events such as emergent intubation, unanticipated hospitalization or permanent injury. CONCLUSION CAPS appears to be a safe, effective and efficient means of providing moderate sedation for colonoscopy in relatively healthy patients. Recovery times were much shorter than historical measures. There were few adverse events, and no serious adverse events, related to CAPS. | Otto S Lin Danielle La Selva Richard A Kozarek Deborah Tombs Wade Weigel Ryan Beecher Johannes Koch Susan Mc Cormick Michael Chiorean Fred Drennan Michael Gluck Nanda Venu Michael Larsen Andrew Ross | 2017 | World Journal of Gastroenterology2017，23，16： | 0 |
