Efficacy of High Flow Nasal Cannula in Reducing Hypoxemia in Children Undergoing Elective Flexible Fibreoptic Bronchoscopy as Compared to Conventional Low Flow Nasal Cannula: A Randomized Controlled Trial

Listen to this summary

This study aimed to evaluate the efficacy and safety of high-flow nasal cannula (HFNC) compared to low-flow nasal cannula (LFNC) in preventing hypoxemia during elective flexible fibreoptic bronchoscopy (FFB) in children. The results indicated no significant difference in hypoxemia rates between the two groups, suggesting that HFNC does not provide a clear advantage over LFNC in this context, although the study may have lacked sufficient power to detect smaller differences.
