Randomized Controlled Trial Comparative Study
Carbon dioxide insufflation for more comfortable endoscopic retrograde cholangiopancreatography: a randomized, controlled, double-blind trial.
The effect on abdominal pain of using carbon dioxide (CO2) for insufflation during endoscopic retrograde cholangiopancreatography (ERCP) has not been investigated. The present study aimed to compare CO2 insufflation with standard air insufflation with respect to the pain experienced during and after ERCP. In addition, we investigated the effect of CO2 insufflation on the partial pressure of CO2 (Pco2). ⋯ Carbon dioxide insufflation during ERCP significantly reduces postprocedural abdominal pain. No side effects were observed. Carbon dioxide should be the standard gas used for insufflation in ERCP.

The correct placement of an enteral feeding tube in the duodenum in critically ill patients is usually controlled radiographically. However, a direct bedside method that obviates the need for exposure to radiation would be preferable. The aim of this study was to demonstrate the usefulness of bedside sonographic position control for placing enteral feeding tubes in critically ill patients. ⋯ Bedside sonographic control of the positioning of enteral feeding tubes is very sensitive and can be a valuable alternative to radiological control, especially in patients without open abdominal wounds, external installations, or extensive abdominal surgery.
