Arterial blood gas tensions during upper gastrointestinal endoscopy.
Arterial blood gas tensions were measured before and during upper gastrointestinal endoscopy, with (group I) and without (group 2) sedation with intravenous diazepam. There was a highly significant fall in the PaO2, which occurred in both groups and was therefore not attributable to diazepam. Measurement of FEV, and FVC before endoscopy had no predictive value for those patients whose PaO2 fell...
متن کاملpredictive factors of arterial blood oxygen desaturation during upper gastrointestinal endoscopy in nonsedated patients
introduction: hypoxemia can occur during upper gastrointestinal endoscopy with or without pharmacological sedation. pulse oximetry saturation (spo2) levels were assessed in patients attending for routine unsedated diagnostic upper gastrointestinal endoscopy to identify factors associated with oxygen desaturation. methods: a total of 300 patients who underwent upper gastrointestinal endoscopy wi...
متن کاملThe cardiovascular changes during upper gastrointestinal endoscopy
Tracheal intubation under general anaesthesia causes a rise in heart rate and blood pressure. This can worsen myocardial ischaemia or precipitate infarction in patients with coronary artery disease. We monitored 50 sedated and non-sedated patients undergoing upper gastrointestinal endoscopy with continuous non-invasive blood pressure monitoring. We subsequently studied 15 patients undergoing en...
متن کاملCardiorespiratory changes during upper gastrointestinal endoscopy.
OBJECTIVES To determine the changes in oxygen saturation, blood pressure and heart rate during various endoscopic procedures and to find out the risk factors for these changes. METHODS Forty patients without cardiorespiratory disorders were recruited. Oxygen saturation, blood pressure and pulse rate were monitored during endoscopy using pulse oximeter and automated blood pressure monitor. The...
