(Press-News.org) Washington, DC (May 19, 2015) -- Use of computer-assisted propofol sedation for routine upper endoscopy and colonoscopy reduced recovery room time by almost 20 percent, according to a study (abstract 1054) released today at Digestive Disease Week® (DDW) 2015. The study, conducted by researchers at Virginia Mason Medical (VMMC) Center, Seattle, WA, showed the process yielded a better recovery experience than the commonly used combination of midazolam and fentanyl.
"Some patients do not respond well to sedation with midazolam and fentanyl, and others find that these two medications cause them to be in a 'fog' immediately after they wake up," said Andrew Ross, MD, section chief for gastroenterology and director of the Therapeutic Endoscopy Center of Excellence at the Digestive Disease Institute at VMMC. "Results from our study demonstrate that clinicians can use computer-assisted propofol sedation (CAPS) for these patients and shorten their recovery time."
Seeing the need for an alternative to midazolam and fentanyl sedation, gastroenterologists and anesthesiologists at VMMC came together to test the CAPS system to see if it could be a safe and effective sedation system for their routine upper endoscopy and colonoscopy patients.
In their study, researchers utilized the CAPS system on 1,466 patients who were either Class 1 (considered normal and healthy) or Class 2 (suffer from mild systemic diseases), as defined by the American Society of Anesthesiologists (ASA). After undergoing their endoscopic procedure, CAPS patients had an average recovery time of 27 minutes, which was 6 minutes or, almost 20 percent, faster than similar patients at VMMC who underwent sedation with midazolam and fentanyl.
Normally, sedation using propofol requires that an anesthesiologist be present during each endoscopic procedure. However, with computer-assisted sedation, anesthesiologists do not have to be involved in each procedure, but must be available when needed, giving hospitals and health systems the ability to more efficiently staff the procedures.
"Early results from patient and clinician experience surveys suggest that satisfaction scores with computer-assisted propofol sedation are higher for both patients and clinicians compared to standard procedures," said Dr. Ross. "Clinicians provided a much higher satisfaction score, because they believe CAPS provided a better level of sedation than other methods, while patients reported a slightly higher satisfaction score focusing on their recovery."
Dr. Ross added that, while the data demonstrate that computer-assisted propofol sedation worked well, the sedation method cannot be used with all patients. The evidence supports use of CAPS only in Class 1 and Class 2 patients.
Researchers suggest that additional studies should be conducted to see if there may be any other benefits to CAPS, beyond reducing recovery time, such as how it may change work flow in a hospital's endoscopic unit. They also believe further patient analysis should be done to determine what factors make for an ideal CAPS patient.
Dr. Andrew Ross will present data from the study "The first U.S. experience with computer assisted propofol sedation," abstract 1054, on Tuesday, May 19, at 4:45 p.m. ET, in room 152 of Walter E. Washington Convention Center. For more information about featured studies, as well as a schedule of availability for featured researchers, please visit http://www.ddw.org/press.

WASHINGTON, DC -- May 19, 2015 -- It's no wonder that giant pandas are always chewing and eating, say Chinese researchers: their gut bacteria are not the type for efficiently digesting bamboo.
The bamboo-eating giant panda actually harbors a carnivore-like gut microbiota predominated by bacteria such as Escherichia/Shigella and Streptococcus, according to new research published this week in mBio®, the online open-access journal of the American Society for Microbiology.
"Unlike other plant-eating animals that have successfully evolved, anatomically specialized digestive ...
WASHINGTON - Inducing a sense of awe in people can promote altruistic, helpful and positive social behavior according to research published by the American Psychological Association.
"Our investigation indicates that awe, although often fleeting and hard to describe, serves a vital social function. By diminishing the emphasis on the individual self, awe may encourage people to forgo strict self-interest to improve the welfare of others," said Paul Piff, PhD, assistant professor of psychology and social behavior at the University of California, Irvine. He was lead author ...
(PARIS, FRANCE) -- Two year outcomes in a study comparing implantation of transcatheter and surgical bioprosthestic aortic valves shows that the less invasive procedure is safe and effective, and comparable to the gold standard, surgical valve replacement, in patients whose operational risk was lower than that of patients studied in the pivotal randomized trials for these new devices.
Dr. Lars Søndergaard from the Heart Center, Rigshospitalet, Copenhagen University Hospital, Denmark presented the results of the Nordic Aortic Valve Intervention (NOTION) trial here ...

Antiretroviral therapy (ART) has proven lifesaving for people infected with HIV; however, the medications are a lifelong necessity for most HIV-infected individuals and present practical, logistical, economic and health-related challenges. A primary research goal is to find an HIV cure that either clears the virus from an infected person's body or enables HIV-infected individuals to suppress virus levels and replication to extremely low levels without the need for daily ART.
In a new perspective article, National Institute of Allergy and Infectious Diseases (NIAID) ...
Apremilast (trade name: Otezla) has been available since January 2015 for the treatment of moderate to severe plaque psoriasis or active psoriatic arthritis in adult patients in whom certain pretreatments are not sufficiently effective or unsuitable. The German Institute for Quality and Efficiency in Health Care (IQWiG) examined in two dossier assessments whether this drug offers an added benefit over the respective appropriate comparator therapy. Such an added benefit cannot be derived from any of the dossiers however, because they contain no relevant data.

Suffering from anxiety or depression could carry an increased risk of death from liver disease, a study suggests.
The study is the first to identify a possible link between high levels of psychological distress and deaths resulting from a variety of liver diseases.
Reasons for this are unclear as the biological links between psychological distress and liver disease are not well understood, researchers say.
Previous research suggests mental distress can put people at increased risk of cardiovascular disease. At the same time, risk factors for cardiovascular disease ...
(PARIS, FRANCE) -- Experts speaking at EuroPCR 2015 say the explosion of positive results for new-generation endovascular devices for the treatment of acute stroke warrant a call to action to ensure swifter implementation of this technology. Known as "stent-retrievers," mechanical thrombectomy devices use catheters introduced into a blocked cerebral artery to suck out or lyse a clot that is cutting off circulation to part of the brain.
On Tuesday, EuroPCR 2015 featured a special breaking news session devoted to this rapidly evolving field to review the recent evidence ...
(PARIS, FRANCE) - Experts participating in a European Clinical Consensus Conference (CCC) have concluded that research into the use of renal denervation for high blood pressure in patients unable to control the disease using a multi-drug regimen should not be abandoned until high-quality research is completed according to agreed-upon standards. [1]
"Focused, collaborative high-quality research will be necessary to ensure that future patients are neither denied an effective therapy, nor needlessly put at risk from procedures that bring no benefits," the authors, led by ...
Sending teen girls periodic text messages reminding them to follow through on their clinic appointments for periodic birth control injections can go a long way toward improving timing and adherence to contraception in an age group that is notoriously noncompliant, according to a small study from the Johns Hopkins Children's Center.
"Our findings suggest that text messaging can help overcome some issues that teens struggle with and pose challenges for the clinicians caring for them, such as keeping clinical appointments, adhering to a tight treatment schedule and regularly ...
