Abstract: The aim of this study was to evaluate the prevalence of hypoxia related to midazolam sedation during upper gastrointestinal endoscopy. This single blind randomized placebo control clinical trial, carried out on 180 patients who referred to endoscopy clinic at Imam Khomeini Hospital for selective upper gastrointestinal endoscopy from April to July in 2008. Informed consents obtained from all participants. Patients under 18 years old, obese, pervious history of asthma, COPD and cigarette smoking were excluded. Arterial hemoglobin saturation controlled by finger probe pulse oximetry. After pharyngeal lidocaine spray, midazolam was administered intravenously in case group and patients in controlled group received placebo. Demographic characteristics and other variables were recorded in a questionnaire and data analyzed using SPSS software. Gastrointestinal disturbances and epigastric pain were major indications of endoscopies. The most common endoscopic diagnoses were deudonitis, esophagitis or gastroesophagial reflux. No patients had any serious episode of hypoxia and the incidence of mild hypoxia was not significant in both studied group (p = 0.823). There was no significant difference in arterial oxygen saturation recorded by the three endoscopists (p = 0.734). Our data showed that optimal dose of sedation had no hypoxia. So that, we recommend sedative endoscopy in patients without risk factors for hypoxia.
