Patient Positioning Guidelines for Gastrointestinal Endoscopic Procedures.

Patient positioning during gastrointestinal endoscopic procedures has received minimal attention compared with surgical procedures performed in the surgical setting. However, prolonged endoscopic interventions on patients and the increasing requirement for general anesthesia have changed to need for patient positioning guidelines. The objective of this study was to test whether patient positioning guidelines for surgical procedures in surgical suites are suitable for gastrointestinal endoscopic procedures without negatively impacting safety and procedure duration.

An in vitro and clinical dose-finding study of antifoaming effects of simethicone during colonoscopy.

Simethicone is an antifoaming agent frequently added to endoscopic rinse solutions but has recently been implicated as a risk factor for transmission of infections due to the formation of simethicone deposits within scope channels. Since the build-up of residue is likely dose-related, the smallest effective dose of simethicone should be used but there are no data available on the effective dose. Thus, we conducted a dose-finding study in an "in vitro bubble model" to determine the appropriate simethicone dose.
