Primary outcomes of the study included extubation failure at 72 hours and at 7 days.ResultsNine clinical trials were included, encompassing 1471 infants. Extubation failure at 72 days was more common with HHHFNC although insignificantly (OR = 3.40, 95% CI: 0.87, 13.23), but it was found to be significantly higher at 7 days when opting for HHHFNC (OR = 1.65, 95% CI: 1.02, 2.67). In an overall analysis, extubation failure was significantly higher in infants treated with HHHFNC (OR = 1.61, 95% CI: 1.14, 2.26). Among secondary outcomes, nasal trauma was significantly higher when CPAP was utilized (OR = 0.20 95% CI: 0.10, 0.42). Meta-analysis suggests that there are no differences in the risks for BPD (OR = 1.27, 95% CI: 0.79, 2.06), ROP (OR = 0.88, 95% CI: 0.51, 1.52), NEC (OR = 0.63, 95% CI: 0.41, 0.97), PVL (OR = 0.71, 95% CI: 0.29, 2.96), IVH (OR = 1.04, 95% CI: 0.53, 2.04), and mortality (OR = 0.96, 95% CI: 0.56, 1.66).ConclusionAccording to our review, CPAP remains the choice of non-invasive respiratory support modality regarding its lower risk for extubation failure.

Although liver impairment has not been commonly reported as a side effect of diazoxide, previous reports, such as one by Tas et al. in 2015, have documented similar findings in patients with hypoalbuminemia, where altered drug metabolism may play a role.
