Review Meta Analysis Comparative Study
Bispectral Index Versus Standard Monitoring in Sedation for Endoscopic Procedures: A Systematic Review and Meta-Analysis.
Bispectral index (BIS ) monitoring has been used as an objective measurement tool for sedation depth and has been proposed as a guidance to reduce the risk of intraprocedural over-sedation. However, the results of several studies evaluating the benefits of BIS monitoring for gastrointestinal endoscopy were not consistent. ⋯ This first meta-analysis showed that BIS monitoring appears to be an effective and safe method for avoiding unnecessary administration of propofol and for providing adequate sedation during endoscopic procedures.

Hepatopulmonary syndrome (HPS) is a pulmonary complication observed in patients with chronic liver disease and/or portal hypertension, attributable to an intrapulmonary vascular dilatation that may induce severe hypoxemia. Microvascular dilation and angiogenesis in the lung have been identified as pathologic features that drive gas exchange abnormalities in experimental HPS. Pulse oximetry is a useful screening test for HPS, which can guide subsequent use of arterial blood gases. ⋯ The presence of HPS increases mortality and impairs quality of life, but is reversible with liver transplantation. No medical therapy is established as effective for HPS. At the present time, liver transplantation is the only available treatment for HPS.

In May 2013, the FDA (Federal Drug Administration) approved SEDASYS(®), a device that enables non-anesthesia physicians to provide mild-to-moderate sedation to patients undergoing colonoscopy and esophagogastroduodenoscopy. SEDASYS(®) is the first among the devices being built to provide computer-assisted personalized sedation. ⋯ Deep sedation is required frequently for a successful completion of the procedure, which poses unforeseen challenges. The present review aims to provide clear information to the users regarding pre-procedure assessment, possible sedation related complications and management options.

The anesthesia community is still divided as to the appropriate airway management in patients undergoing endoscopic retrograde cholangiopancreatography. Increasingly, gastroenterologists are comfortable with deep sedation (normally propofol) without endotracheal intubation. There are no comprehensive reviews addressing the various pros and cons of an un-intubated airway management. ⋯ The reasons to avoid routine endotracheal intubation and the approaches for an un-intubated anesthetic management are discussed. The special situations where endotracheal intubation is the preferred approach are mentioned. Many special techniques to manage airway are illustrated.

Inflammatory bowel disease frequently begins during childhood or adolescence. Current tests and procedures for diagnosing and monitoring inflammatory bowel disease are invasive, uncomfortable and costly. Fecal calprotectin is an inflammatory marker tested in several studies including pediatric patients with inflammatory bowel disease. ⋯ The fecal calprotectin test could be used for supporting diagnosis or confirming relapse of inflammatory bowel disease in pediatric patients. A positive result could confirm the suspicion of either inflammatory bowel disease diagnosis or inflammatory bowel disease relapse, due to the high sensitivity of the test, but a negative result should not exclude these conditions, due to its moderate specificity.
