Original Article: Clinical EndoscopyA national study of cardiopulmonary unplanned events after GI endoscopy
Section snippets
Patients and methods
Data on GI endoscopies from April 1997 to March 2002 reported in the CORI database were queried. The data on EUS were available from February 1998. Flexible sigmoidoscopies, unsedated endoscopies, and endoscopies performed under propofol or general anesthesia were excluded from the analysis. Data on patient demographics and American Society of Anesthesia (ASA) class, type of procedure, type and dose of conscious sedation and reversal medications, and use of routine supplemental oxygen during
Results
Between April 1997 and March 2002, 335,249 endoscopic procedures, 991 (0.3%) without sedation, 324,737 (96.9%) with conscious sedation, and 9532 (2.8%) under general anesthesia, were reported in the CORI database. Unplanned events were reported in 4477 (1.4%) of the procedures performed with conscious sedation, of which 3011 (0.9%) were cardiopulmonary unplanned events. Complete data on analyzed variables were available in 247,889 (76%) procedures, and these were included in the multiple
Discussion
Conscious sedation is associated with greater patient tolerance and satisfaction with GI endoscopy; hence most endoscopies are performed under conscious sedation.9, 10 Because of central cardiorespiratory depression, conscious sedation is associated with a small but finite risk of cardiopulmonary unplanned events, which remain the leading cause of morbidity and mortality with GI endoscopy.1, 2, 3, 4, 5, 6, 7 The incidence of and factors responsible for cardiopulmonary unplanned events in
