Randomized Controlled Trial Multicenter Study
Capnographic monitoring of propofol-based sedation during colonoscopy.
Capnography enables the measurement of end-tidal CO2 and thereby the early detection of apnea, prompting immediate intervention to restore ventilation. Studies have shown that capnographic monitoring is associated with a reduction of hypoxemia during sedation for endoscopy and early detection of apnea during sedation for colonoscopy. The primary aim of this prospective randomized study was to evaluate whether capnographic monitoring without tracheal intubation reduces hypoxemia during propofol-based sedation in patients undergoing colonoscopy. ⋯ In patients undergoing colonoscopy during propofol-based sedation capnography monitoring with a simple and inexpensive device reduced the incidence of hypoxemia.
