Introduction: High-flow nasal cannulas (HFNC) have proven to be useful in different clinical settings, because they provide a CPAP of 8-10 cmH2O and can administer air/oxygen mixtures. Their use has been established in the ICU unit and the pre and postoperative care units. There are very little clinical investigations regarding the use of these cannulas in the ambulatory anesthesia setting. The aim of this study is to observe the incidence of descent in peripheral oxygenation (defined as SpO2 <90%) in subjects submitted to gastrointestinal endoscopy using HFNC versus those with standard low-flow nasal cannulas.

Methodology: The study was developed in the endoscopy unit of the ABC Medical Center in Mexico City. 42 patients were enrolled in the study; 28 patients in the control group with low-flow nasal cannulas and 14 in the study group with HFNC.

Results: There was only one episode of desaturation in the study group whilst there were 13 cases in the control group. The demographic and study data collected were subjected to a Mann-Whitney U test. Vital signs were measured at 3 different points during the study; basal, at the beginning and at the end of the procedure. The basal SpO2 and the desaturation frequency were the only with statistical significance with a p of 0.016 and .04 respectively.

Conclusions: The use of HFNC has proven to be a safe strategy of oxygen delivery to patients undergoing gastrointestinal endoscopy due to the CPAP it provides, reducing the risk of desaturation.
