Capnography improves detection of apnea during procedural sedation for percutaneous transhepatic cholangiodrainage.

ABSTRACT:

Background

Capnography provides noninvasive monitoring of ventilation and can enable early recognition of altered respiration patterns and apnea.

Objective

To compare the detection of apnea and the prediction of oxygen desaturation and hypoxemia using capnography versus clinical surveillance during procedural sedation for percutaneous transhepatic cholangiodrainage (PTCD).

Methods

Twenty consecutive patients scheduled for PTCD were included in the study. All patients were sedated during the procedure using midazolam and propofol. Aside from standard monitoring, additional capnographic monitoring was used and analyzed by an independent observer.

Results

The mean (± SD) cumulative duration of apnea demonstrated by capnography was significantly longer than the mea
