title: Prevention of hypoxaemia during upper-gastrointestinal endoscopy by means of oxygen via nasal cannulae.
abstract: Hypoxaemia during oesophagogastroduodenoscopy is well documented and contributes to cardiac arrhythmias and occasional deaths from endoscopy. In 50 patients sedated with intravenous midazolam and examined with a large-diameter endoscope, oxygen desaturation was abolished by giving oxygen (2 litres/min) by way of nasal cannulae throughout the procedure.
