Computer-assisted personalized sedation
Gastrointestinal endoscopy (Impact Factor: 5.37). 03/2011; 73(3):423-7. DOI: 10.1016/j.gie.2010.10.035
The American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee provides reviews of new or emerging endoscopic technologies that have the potential to have an impact on the practice of GI endoscopy. Evidence-based methodology is used, with a MEDLINE literature search to identify pertinent preclinical and clinical studies on the topic, and a MAUDE (Manufacturer and User Facility Device Experience; U.S. Food and Drug Administration Center for Devices and Radiological Health) database search to identify the reported complications of a given technology. Both are supplemented by accessing the "related articles" feature of PubMed and by scrutinizing pertinent references cited by the identified studies. Controlled clinical trials are emphasized but, in many cases, data from randomized, controlled trials are lacking. In such cases, large case series, preliminary clinical studies, and expert opinions are used. Technical data are gathered from traditional and Web-based publications, proprietary publications, and informal communications with pertinent vendors. For this review, the MEDLINE database was searched through January 2010 using the keywords "computer," "computerized," "computer-assisted," "sedation," "propofol." Reports on Emerging Technology are drafted by 1 or 2 members of the ASGE Technology Committee, reviewed and edited by the committee as a whole, and approved by the Governing Board of the ASGE. These reports are scientific reviews provided solely for educational and informational purposes. Reports on Emerging Technology are not rules and should not be construed as establishing a legal standard of care or as encouraging, advocating, requiring, or discouraging any particular treatment or payment for such treatment.

ABSTRACT: There are limited data on the safety of anesthesia-assisted endoscopy by using propofol-mediated sedation in obese individuals undergoing advanced endoscopic procedures (AEPs). To study the association between obesity (as measured by body mass index [BMI]) and the frequency of sedation-related complications (SRCs) in patients undergoing AEPs. Prospective cohort study. Tertiary referral center. A total of 1016 consecutive patients undergoing AEPs (BMI <30, 730 [72%]; 30-35, 159 [16%]; >35, 127 [12%]). Monitored anesthesia sedation with propofol alone or in combination with benzodiazepines and/or opioids. SRCs, airway maneuvers (AMs), hypoxemia, hypotension requiring vasopressors, and early procedure termination were compared across 3 groups. There were 203 AMs in 13.9% of patients, hypoxemia in 7.3%, need for vasopressors in 0.8%, and premature termination in 0.6% of patients. Increasing BMI was associated with an increased frequency of AMs (BMI <30, 10.5%; 30-35, 18.9%; >35-26.8%; P < .001) and hypoxemia (BMI <30, 5.3%; 30-35, 9.4%; >35, 13.4%; P = .001); there was no difference in the frequency of need for vasopressors (P = .254) and premature termination of procedures (P = .401). On multivariable analysis, BMI (odds ratio [OR] 2.0; 95% CI, 1.3-3.1), age (OR 1.1; 95% CI, 1.0-1.1), and American Society of Anesthesiologists class 3 or higher (OR 2.4; 95% CI, 1.1-5.0) were independent predictors of SRCs. In obese individuals (n = 286), there was no difference in the frequency of SRCs in patients receiving propofol alone or in combination (P = .48). Single tertiary center study. Although obesity was associated with an increased frequency of SRCs, propofol sedation can be used safely in obese patients undergoing AEPs when administered by trained professionals.Gastrointestinal endoscopy 12/2011; 74(6):1238-47.

ABSTRACT: This article reviews the principal aspects related to sedation in endoscopy and to the prevention of adverse events in some of the most frequently performed therapeutic upper gastrointestinal (GI) endoscopic procedures (esophageal dilation and stenting, endoscopic resection of upper GI early neoplasia, hemostasis of upper GI bleeding and percutaneous endoscopic gastrostomy insertion). These procedures have an inherent risk of negative outcomes that cannot be entirely avoided. Endoscopic procedures are best performed by well-trained, competent and thoughtful endoscopists in facilities suited to provide for patient safety. Attention to clinical risk management may effectively reduce the frequency and intensity of adverse events, enhance recognition and early detection, and improve responsiveness.Expert review of gastroenterology & hepatology 06/2012; 6(3):271-90.

ABSTRACT: Sedation practices for gastrointestinal endoscopic (GIE) procedures vary widely in different countries depending on health system regulations and local circumstances. The goal of procedural sedation is the safe and effective control of pain and anxiety, as well as to provide an appropriate degree of memory loss or decreased awareness. Sedation-related complications in gastrointestinal endoscopy, once occurred, can lead to significant morbidity and occasional mortality in patients. The risk factors of these complications include the type, dose and mode of administration of sedative agents, as well as the patient's age and underlying medical diseases. Complications attributed to moderate and deep sedation levels are more often associated with cardiovascular and respiratory systems. However, sedation-related complications during GIE procedures are commonly transient and of a mild degree. The risk for these complications while providing any level of sedation is greatest when caring for patients already medically compromised. Significant unwanted complications can generally be prevented by careful pre-procedure assessment and preparation, appropriate monitoring and support, as well as post-procedure management. Additionally, physicians must be prepared to manage these complications. This article will review sedation-related complications during moderate and deep sedation for GIE procedures and also address their appropriate management.11/2013; 5(11):527-533.
