Abstract

Respiratory support in infants with respiratory distress syndrome (RDS) plays an important role in the reduction of mortality and complications, but the treatment fails in some infants. This study aimed to identify the predictors of continuous positive airway pressure (CPAP) failure in preterm infants with RDS. This cross-sectional retrospective study was conducted on RDS-diagnosed preterm infants admitted to the neonatal intensive care unit of Fatemieh Hospital (Hamadan city) in 2021-2022. The infants were examined in terms of risk factors for CPAP failure. Data extracted from the medical records were recorded in a checklist and analyzed with SPSS version 21 software at a confidence level of 95%. CPAP failure was recorded in 37.6% of the studied 202 infants. The need for resuscitation at birth, low gestational age, low birth weight, multiple births, low 1-min and 5-min Apgar scores, the need for higher FIO2 and PEEP, acidosis, and the need for surfactant administration were significantly associated with CPAP failure. In logistic regression, low gestational age (OR 1.30, 95% CI: 1.082-1.576) and the need for resuscitation at birth (OR 0.426, 95% CI: 0.202-0.898) were the major predictors of CPAP failure. Lower gestational age and the need for PPV in the delivery room are good predictors of CPAP failure in preterm infants with RDS, who receive nasal CPAP as primary respiratory support.
