Hyaline membrane disease treated with early nasal end-expiratory pressure: one year's experience
Insights
Nasal end-expiratory pressure (NEEP) improved survival rates for infants with hyaline membrane disease (HMD), particularly those weighing 1,501 to 2,000 gm. This simple technique also significantly reduced the need for endotracheal intubation in HMD patients.
Area of Science:
- Neonatal Medicine
- Pediatric Respiratory Care
Background:
- Hyaline membrane disease (HMD) is a significant cause of respiratory distress in newborns.
- Traditional treatment often involved endotracheal intubation.
Purpose of the Study:
- To evaluate the efficacy of nasal end-expiratory pressure (NEEP) in treating HMD.
- To compare outcomes with and without early NEEP application.
Main Methods:
- A retrospective analysis of 119 HMD infants treated between July 1973 and June 1974.
- Comparison of survival rates, complications, and intubation rates with a previous cohort (1971-1972).
- Early application of NEEP via nasopharyngeal tube in 69 infants.
Main Results:
- Increased survival for all HMD admissions, statistically significant in infants weighing 1,501 to 2,000 gm (P < .01).
- Significant decrease in endotracheal intubations required for HMD (P < .025).
- No significant change in pneumothorax or bronchopulmonary dysplasia incidence.
Conclusions:
- NEEP is a simple, effective method for providing continuous airway distending pressure in neonates.
- Routine endotracheal intubation for infants needing only continuous airway distending pressure is no longer justified.
- Early NEEP application enhances HMD treatment outcomes and reduces invasive procedures.
Abstract:
This report describes one year's experience treating hyaline membrane disease (HMD) with nasal end-expiratory pressure (NEEP). During the 12 months from July 1, 1973 through June 30, 1974, 119 children with HMD were admitted to the Intensive Care Unit of St. Paul Children's Hospital. Sixty-nine infants were treated early in the course of their disease with NEEP. The survival, incidence of complications, and the number of endotracheal intubations are reported and compared to our experience during a similar time period prior to the use of NEEP (1971-1972). Since the advent of the early application of modest amounts of end-expiratory pressure by nasopharyngeal tube, there has been an increase in the survival of all admissions with HMD, but the increase was statistically significant (P less than .01) only in those weighing 1,501 to 2,000 gm. There was a significant decrease (P less than .025) in the total number of children with HMD requiring endotracheal intubation. There was no change in the incidence of pneumothoraces or bronchopulmonary dysplasia. NEEP is a simple and effective technique for creating continuous airway distending pressure. Its effectiveness and ready availability make the routine endotracheal intubation of infants requiring only continuous airway distending pressure no longer justifiable.
