IntroductionThis study provides an evaluation and risk analysis of propofol sedation for endoscopic pulmonary procedures according to our unit's "gastroenterologic nurse-administered propofol sedation (NAPS) guideline".Material And MethodsThe present study is a prospective descriptive study performed at the Endoscopy Unit, Gentofte Hospital, Copenhagen, from May to July 2009. The study comprised at total of 51 consecutive patients who underwent 77 endoscopic procedures. Only patients above the age of 16 years were eligible for treatment. The exclusion criteria were as follows: American Society of Anesthesiologists (ASA) class > 3, history of sedation-related complications, severe chronic obstructive pulmonary disease. Excluded were patients with a potentially difficult airway and ventricular retention. Data on the number and type of procedure, baseline characteristics, sedation time, propofol dose administered and adverse events were obtained from medical histories.ResultsA total of 23 cases of adverse events were recorded, including one event of hypotension and 22 events of hypoxaemia. Five patients needed assisted ventilation. The frequency of hypoxaemia in sessions involving bronchoscopy was 17 of 26 (65%) compared with transoesophageal endoscopic ultrasound (EUS) (17 of 45, 35%) and endoscopic bronchial ultrasound (EBUS) (three of six, 50%). Endoscopist assessment of working conditions was good and patient assessment of discomfort was low. No patients required endotracheal intubation and there was no mortality.ConclusionThis study supports the conclusion that propofol administered by nurses provides for good working conditions and satisfied patients. But our "NAPS for endoscopic gastroenterologic procedures" guideline was unsuited for endoscopic pulmonary procedures including EUS.FundingThis work was supported by the START research foundation at Gentofte Hospital.Trial Registrationnot relevant.
