Summary

Hypoxia frequently occurs as a complication during upper gastrointestinal endoscopic procedures performed under deep sedation. Traditional oxygen delivery methods, such as the simple nasal cannula, are commonly used to prevent hypoxia in these cases. The high-flow nasal cannula, capable of delivering FiO2 levels of up to 1 and flow rates of up to 70 l/min, offers additional benefits, including positive end-expiratory pressure and reduced dead space. We hypothesized is that the use of high-flow nasal cannula can decrease the incidence of hypoxia in comparison to simple nasal cannula in patients undergoing upper gastrointestinal endoscopic procedures under deep sedation.

This was prospective, comparative observational study conducted in a tertiary care center of Nepal with the primary objective to compare the rates of hypoxia (SpO2 \< 92%) and secondary objectives were to compare interruption of procedure due to hypoxia, minimum hypoxia level and episodes of hypoxia between high flow nasal canula (flow rate of 30l/min with FiO2 of 0.5) and simple nasal canula (flow rate of 6l/min) in patients undergoing upper gastrointestinal endoscopic procedures in semi-prone position in deep sedation using propofol infusion.

The study comprised 125 participants, 58 in simple nasal canula and 67 in high flow nasal cannula group. The incidence of hypoxia in simple nasal cannula and high flow nasal cannula groups, with rates of 37.3% (22/58) and 16.4% (11/67), respectively. The relative risk (RR) of hypoxia was 0.43 (95% CI: 0.23-0.81), with a p-value of 0.009. Procedural interruptions due to hypoxia occurred in 8.6% (5/58) of participants in the simple nasal cannula group and 4.47% (3/67) in the high flow nasal cannula group, with RR of 0.17 (95% CI: 0.02-1.41) and a p-value 0.1. Furthermore, the occurrence of multiple episodes of hypoxia was higher in the simple nasal cannula group compared to the high flow nasal cannula group (5 vs. 0), with a p-value \< 0.001.The use of high flow nasal cannula reduces the occurrence of hypoxia in patients undergoing upper gastrointestinal endoscopic procedures with deep sedation compared to simple nasal cannula.
