Subgroup analysis
In infants with a gestational age of ≥32 weeks, the rate of successful intubation without physiological instability during all intubation attempts was significantly higher (p = 0.014) in the NIPPV group. This rate was also higher in the practitioners with an intubation experience of <36 intubations (p = 0.026) (Table 3). Results for other physiological parameters are shown in Table 3.
No significant difference was noted between the groups in terms of the vital signs measured five minutes after the procedure, the blood gas values obtained one hour after the procedure, and intubation-associated adverse events (Table 4).
