Abstract
Invasive mechanical ventilation in very-low-birth-weight infants (VLBWI) was associated with immediate and long-term complications. Nasal high-frequency oscillation (nHFO) has recently become a new non-invasive ventilation (NIV) mode for treating respiratory failure in VLBWI. This study aimed to investigate the safety and efficacy of nHFO as an alternative respiratory support to prevent intubation in VLBWI. A retrospective analysis was conducted using the clinical data of 42 VLBWIs with respiratory distress syndrome (RDS) who were treated in our department from August 2018 to August 2020 and met the selection criteria. nHFO was used as a rescue strategy in 32 infants and a prophylactic strategy in 10 infants. It was observed that out of 42 cases, 30 cases (71.4%) were able to avoid intubation within 72h, while 23 cases (54.8%) were successfully switched to another NIV mode from nHFO. There was a significant decrease in pCO2 and an increase in pH 1h after using nHFO in the success group. Two cases (4.8%) of feeding intolerance associated with nHFO were noted. This study showed that nHFO as alternative respiratory support for preterm infants with RDS might be safe and effective in reducing the need for intubation.
