Diagnostic point-of-care ultrasound (POCUS) is a growing field across all disciplines of pediatric practice. Machine accessibility and portability will only continue to grow, thus increasing exposure to this technology for both providers and patients. Individuals seeking training in POCUS should first identify their scope of practice to determine appropriate applications within their clinical setting, a few of which are discussed within this article. Efforts to build standardized POCUS infrastructure within specialties and institutions are ongoing with the goal of improving patient care and outcomes.

Management of patent ductus arteriosus in extremely preterm infants remains a topic of debate. Treatment to produce ductal closure was widely practiced until the past decade, despite lack of evidence that it decreases morbidities or mortality. Meta‐analyses of trials using nonsteroidal anti‐inflammatory drugs have shown effectiveness in accelerating ductal closure, but no reduction in neonatal morbidities, regardless of agent used, indication, timing, gestational age, or route of administration. Surgical ligation closes the ductus but is associated with adverse effects. Recent experience with conservative approaches to treatment suggest improved neonatal outcomes and a high rate of spontaneous ductal closure after discharge. Careful postdischarge follow‐up is important, however, because potential adverse effects of long‐standing aortopulmonary shunts may be an indication for catheter‐based ductal closure. Identification of extremely preterm infants at greatest risk of potential harm from a persistently patent ductus, who may benefit most from treatment are urgently needed.

CDH newborns have evidence of biventricular dysfunction and decreased cardiac output. Abnormal function may be a factor in the non-response to pulmonary arterial vasodilators in CDH patients. A two-pronged management strategy aimed at improving cardiac function, as well as reducing pulmonary artery pressure in CDH newborns, may be warranted.

Few studies have examined the role that small for gestational age (SGA) status plays in postoperative outcomes for low-birth-weight (LBW) infants with congenital heart disease (CHD). This study aimed to examine the effect of SGA status, gestational and chronologic age, and weight on differences in morbidities and mortalities during the immediate postoperative hospitalization period. The charts of infants with CHD weighing less than 2.5 kg who underwent operative repair during the neonatal period between 2004 and 2011 were reviewed. Infants with an isolated patent ductus arteriosus were excluded from the study. Data on hospital morbidities and mortality before discharge were collected. The study identified 136 LBW infants with a diagnosis of CHD. Among the 74 infants who underwent surgery and had complete chart records, the SGA infants had a higher gestational age at birth (36.8 vs. 32.3 weeks; p < 0.0001). The SGA and non-SGA infants did not differ in terms of survival to discharge or immediate postoperative outcomes. A lower weight at surgery was significantly associated with an increased risk of postoperative infection. In contradistinction, an older postnatal age at surgery was associated with an increased risk of preoperative infection (p < 0.0001). Additionally, lower gestational age at birth was associated with home oxygen use, higher tracheostomy rates, and discharge with a gastrostomy tube. Small for gestational age status played no protective role in the outcome for LBW infants after primary surgery for CHD. A weight of 2.4 kg or greater at the time of surgery was associated with lower rates of postoperative infections. Greater duration of time between birth and surgery was associated with a greater risk of preoperative infection. A gestational age of 32 weeks or more at birth was associated with decreased morbidities, which could influence obstetric management.

Screening for PH in BPD, and subsequent evaluation and management is highly variable.

Pulmonary vascular disease and resultant pulmonary hypertension (PH) have been increasingly recognized in the preterm population, particularly among patients with bronchopulmonary dysplasia (BPD). Limited data exist on the impact of PH severity and right ventricular (RV) dysfunction at PH diagnosis on outcome. The purpose of this study was to evaluate if echocardiography measures of cardiac dysfunction and PH severity in BPD-PH were associated with mortality. The study is a retrospective analysis of the echocardiography at three months or less from time of PH diagnosis. Survival analysis using a univariate Cox proportional hazard model is presented and expressed using hazard ratios (HR). We included 52 patients with BPD and PH of which 16 (31%) died at follow-up. Average gestational age at birth was 26.3 ± 2.3 weeks. Echocardiography was performed at a median of 43.3 weeks (IQR: 39.0–54.7). The median time between PH diagnosis and death was 117 days (range: 49–262 days). Multiple measures of PH severity and RV performance were associated with mortality (sPAP/sBP: HR 1.02, eccentricity index: HR 2.02, tricuspid annular plane systolic excursion Z-score: HR 0.65, fractional area change: HR 0.88, peak longitudinal strain: HR 1.22). Hence, PH severity and underlying RV dysfunction at PH diagnosis were associated with mortality in BPD-PH patients. While absolute estimation of pulmonary pressures is not feasible in every screening echocardiography, thorough evaluation of RV function and other markers of PH may allow to discriminate the most at-risk population and should be considered as standard add-ons to the current screening at 36 weeks.
