Comparison of High Flow Vs Standard Nasal Cannula in Children with Burns Under Sedoanalgesia

The initial flow rate for nasal cannula oxygen was set at 3 L/min. In cases of hypoxia, the oxygen concentration was adjusted by increasing the flow rate by 1 to 2 L/min.

The high-flow nasal oxygenation device was set to a temperature of 36°C and an FiO2 of 0.4. The initial oxygen flow rate for the high flow group was determined according to the age and weight of the patients, based on our pediatric intensive care team's guidelines and the reference from the Slain study. When SpO2 fell below 94%, it was considered hypoxia, and the flow rate was increased by 2 to 4 L/min.

Sedation was done with IV midazolam 0.025 to 0.1 mg/kg, IV ketamine 0.25 to 0.5 mg/kg, and IV propofol (1%) 0.25 to 0.5 mg/kg

Sedation maintenance was done by propofol 0.5 to 1 mg/kg/h
