title: The use of end-tidal carbon dioxide monitoring to confirm endotracheal tube placement in adult and paediatric intensive care units in Australia and New Zealand.
abstract: The use of end-tidal carbon dioxide monitoring to assist in confirming endotracheal tube placement is currently not mandatory in intensive care units (ICUs) in Australia and New Zealand. Early detection of failed tracheal intubation is vital to optimize management and to prevent complications. Questionnaires were sent to the lead clinician/head of department of all 66 intensive care units approved for training purposes by the Joint Faculty of Intensive Care Medicine in Australia and New Zealand. The methods used to confirm correct endotracheal tube placement, the availability of end-tidal carbon dioxide monitoring and its role in confirming endotracheal tube placement in the intensive care unit were explored. Completed questionnaires were received from 61 of the 66 centres (92.4%). Wide variation in the method of confirmation of endotracheal tube position was demonstrated, with 23 (37.7%) of units using sub-optimal methods. Sixty (98.3%) of units had end-tidal carbon dioxide monitoring available. Thirty-eight (62%) units shared monitors between several beds; and 22 (36%) had one monitor per bed. End-tidal carbon dioxide monitoring was used routinely to confirm endotracheal tube placement in 42 (68.8%) units. Fifty-two respondents (83.3%) felt that end-tidal carbon dioxide monitoring was superior to other methods for confirming endotracheal tube placement in critically ill patients. Thirty-eight respondents (62.3%) thought that end-tidal carbon dioxide monitoring should be mandatory to confirm tracheal intubation in the intensive care unit. If it were available, 42 respondents (68.8%) would use end-tidal carbon dioxide monitoring for confirmation of every intubation. Mandatory end-tidal carbon dioxide confirmation of endotracheal tube placement was policy in 33 (54.1%) of the intensive care units.
