Helping High Risk Infants and Parents Sleep Better: ATS Guidelines for Outpatient Care of Premature Infants

Premature infants, particularly born before 30 weeks gestation who have been given a diagnosis of chronic lung disease, bronchopulmonary dysplasia, or post-prematurity respiratory disease face significant challenges in transition from the NICU environment to life at home.  The lack of guidelines to help focus care and quality medical literature differentiating outcomes is stark.  Parents and physicians need tools to care for these high risk infants. These new ATS guidelines nicely evaluate the role of inhaled medications, swallowing assessment, airway endoscopy, and especially sleep testing and provide timely recommendations.

Outpatient Respiratory Management of Infants, Children, and Adolescents with Post-Prematurity Respiratory Disease: An Official American Thoracic Society Clinical Practice Guideline

New recommendations are available to help guide physicians who must determine when and how to treat infants, children and adolescents with post-prematurity respiratory disease (PPRD). The American Thoracic Society has published an official clinical practice guideline in which a multidisciplinary panel of experts provide 13 conditional recommendations on the diagnostic testing and clinical management of these young people. The complete guideline detailing these recommendations was posted online ahead of print in the American Journal of Respiratory and Critical Care Medicine.

Worldwide, approximately 12 million infants—10 percent of live births—are born prematurely and are at risk for respiratory disease, the most common of which is bronchopulmonary dysplasia (BPD). However, all premature infants, even those who do not meet the criteria for having BPD, may develop poor respiratory health later in life with signs and symptoms including cough, recurrent wheezing, exercise intolerance, low blood oxygen (hypoxemia) and reduced pulmonary function. These individuals are classified as having PPRD.

Setting Discharge Goals for High Risk Infants

 A useful and much study needed since neonatologists and consulting pediatric pulmonologists rely on few reliable indicators to judge discharge readiness.  And with little guidance, often managed care restrictions may prompt premature discharge.  A baseline CO2 retention above a certain threshold always seemed like at least 1 useful measure, now supported by this South Korean study.

Children with chronic lung disease of prematurity tend to have reduced lung function, increased susceptibility to respiratory viral illness, and elevated risk for rehospitalization.  Setting goals for discharge are greatly needed in this high risk population.

Capillary partial pressure of carbon dioxide for predicting rehospitalization in preterm infants under noninvasive respiratory support with severe bronchopulmonary dysplasia

Abstract

Background

The severity of bronchopulmonary dysplasia (BPD) is an important predictor of prognosis in preterm infants. However, the severity of BPD was determined mainly by the degree of oxygen supplementation and mode of respiratory support.

Objectives

This retrospective study aimed to examine the role of partial pressure of carbon dioxide (pCO2) in predicting rehospitalization among preterm infants with severe BPD without invasive ventilation at 36 weeks' postmenstrual age (PMA).

Methods

We assessed preterm infants aged <32 gestational weeks with severe BPD who were receiving noninvasive respiratory support at 36 weeks' PMA. Patients were compared after stratifying them according to the history of rehospitalization owing to respiratory infection before a corrected age (CA) of 1 year and pCO2 measured by capillary blood gas analysis at 36 weeks' PMA.

Results

Among 54 infants who had severe BPD with noninvasive respiratory support at 36 weeks' PMA, 16 (29.6%) experienced rehospitalization due to respiratory problems. At 36 weeks' PMA, the amount of oxygen supplementation (0.30 vs. 0.28, p = 0.021) and pCO2 (62.1 vs. 53.6 mmHg, p = 0.006) were higher in the rehospitalization group than in the no rehospitalization group. Multivariate logistic analysis findings indicated that pCO2 ≥ 57.4 mmHg was the only factor associated with rehospitalization (adjusted odds ratio: 8.017, 95% confidence interval 1.239–51.859).

Conclusion

High pCO2 during noninvasive respiratory support at 36 weeks' PMA in severe BPD was associated with rehospitalization. Consideration of the degree of impairment in ventilatory capacity may improve the prediction of later respiratory outcomes in infants with BPD.
