The Treatment Outcomes and Related Factors of Inhaled Nitric Oxide in Newborns with Persistent Pulmonary Hypertension at Chonburi Hospital
Abstract
Background: Persistent pulmonary hypertension of the newborn (PPHN) leads to neonatal respiratory failure and death. Currently, inhaled nitric oxide (iNO) is one of the treatments for PPHN. Research on the outcomes of iNO treatment and the factors that affect those outcomes is important for developing more effective care processes for newborns with PPHN.
Objective: To investigate nitric oxide inhalation therapy results and factors predicting treatment outcomes in newborns with PPHN.
Methods: This historical cohort study collected data from newborns with PPHN who received iNO treatment in Chonburi Hospital from September 2019 to September 2023. Chi square test, independent t-test, and logistic regression analysis were used to analyze the factors associated with the outcome of iNO therapy with statistical significance p<0.05.
Results: Ninety-two newborns with PPHN received iNO therapy. The neonatal mortality rate after iNO treatment was 33.7%. The factors affecting the mortality rate included higher heart rate (AOR 1.04, 95%CI 1.01, 1.07) and higher oxygen index (AOR 1.03, 95%CI 1.01, 1.06) when starting iNO therapy, and pulmonary hemorrhage (AOR 4.63, 95%CI 1.37, 15.67).
Conclusions: Newborns with PPHN who were treated with iNO therapy have a survival rate of 66.3%. Factors that associated with treatment outcomes include heart rate and oxygen index before starting therapy, and the existence of pulmonary hemorrhage.
