RESUMO
BACKGROUND: Prostaglandin E1 (PGE1) is used in the medical treatment of ductal-dependent critical congenital heart disease (CCHD) in neonates. Apnea/bradycardia, hypotension, hypokalemia, and fever are the most important side effects of PGE1. Moreover, gastric outlet obstruction has been reported in a few case reports. A prospective study was conducted to investigate the effect of PGE1 treatment on pyloric wall thickness in newborns with congenital heart diseases. METHODS: A total of 22 newborns with ductal-dependent CCHD having PGE1 infusion longer than a week were included in this study. Ultrasonographic measurements were performed before and one week after the PGE1 infusion to evaluate the pyloric thickness and length. The protocol was registered with ClinicalTrials.govidentifier NCT04496050. RESULTS: A total of 22 neonates with mean gestational age 38 ± 1.8 weeks and birth weight 3105 ± 611 gr were enrolled in the study. The median time of the second ultrasound was seven days. The median cumulative dose of PGE1 given during this period was 108 mcg/kg/min. There was a statistically significant increase in post-treatment pyloric thickness and length compared to pre-treatment measurements (p < 0.001, p < 0.001). None of the patients with increased thickness and pyloric muscle length presented any symptoms. CONCLUSION: PGE1 treatment significantly increased the pyloric thickness and length after at least one-week treatment. PGE1 with its action mechanism is likely to cause gastric outlet obstruction, although not exactly pyloric stenosis on the condition used for a long time.

Cardiac catheterization can affect clinical outcomes in patients on extracorporeal membrane oxygenation (ECMO) after congenital heart surgery; however, its effect in this group of patients remains unclear. This study aimed to evaluate the safety and outcome of cardiac catheterization in patients undergoing ECMO after congenital cardiac surgery and determine predictors that influence successful weaning. This retrospective cohort study included pediatric patients who underwent cardiac catheterization while on ECMO after congenital heart surgery in two cardiac centers between November 2012 and February 2020. Predictors of successful weaning from ECMO were studied using univariate and multivariate logistic regression analyses. Of 123 patients on ECMO support after congenital cardiac surgery, 60 patients underwent 60 cardiac catheterizations (31 diagnostic and 29 interventional). Thirty-four (56.7%) and 22 patients (36.7%) underwent successful decannulation from ECMO support and survived after hospital discharge, respectively. Patients who underwent earlier catheterization (within 24 h of ECMO initiation) had more successful weaning from ECMO and survival compared to others. Patients who underwent an interventional procedure (interventional catheterization or redo cardiac surgery after cardiac catheterization) had better survival than those who underwent only diagnostic catheterization (P = 0.038). Shorter durations of ECMO was the most important predictor of successful weaning from ECMO. Early cardiac catheterization greatly impacts successful weaning from ECMO and survival. Patients with correctable lesions amenable either by catheterization or redo surgery are more likely to survive. Shorter durations of ECMO could have a significant influence on successful weaning from ECMO and survival.

BACKGROUND: Critical congenital heart diseases (CCHDs), 10% to 25% of all CHD, are duct-dependent defects that are life threatening without intervention in the neonatal period or infancy. One third of neonates with CCHDs are discharged home undetected and have a poorer outcome. Pulse oximetry screening before discharge is increasingly being used to diagnose CCHDs in developed countries. METHODS: This prospective observational study conducted at a tertiary care hospital from September 2016 to March 2019 screened all asymptomatic intramural neonates after 24 hours of life using a Masimo pulse oximeter with signal extraction technology using the standard American Academy of Pediatrics algorithm. A positive screen was followed by a confirmatory echocardiography (gold standard) and a negative screen by clinical examination at 6, 10 and 14 weeks and identification of readmissions during the study period. RESULTS: A total of 1855 neonates (82.99% of the eligible 2235 neonates) underwent screening at a mean (SD) age at screening of 32.4 (6.8) hours and took a mean (SD) time of 3.5 (1.2) minutes. The sensitivity, specificity, positive and negative predictive value of pulse oximetry screening for detection of CCHDs in asymptomatic neonates was 75% (95% CI: 28.91% to 96.59%), 99.29% (95% CI: 98.79% to 99.60%), 18.75% (95% CI: 5.80% to 43.80%) and 99.94% (95% CI: 99.66 to 99.99%), respectively. CONCLUSION: Pulse oximetry screening of asymptomatic neonates between 24 and 48 hours of life improved the detection of CCHDs with high specificity and negative predictive value, moderate sensitivity and a reasonably low false positivity rate.
RESUMO
BACKGROUND: Prenatal diagnosis and planned peripartum care is an unexplored concept in China. This study aimed to evaluate the effects of the "prenatal diagnosis and postnatal treatment integrated model" for newborns with critical congenital heart disease. METHODS: The medical records of neonates (≤ 28 days) admitted to Fuwai Hospital were reviewed retrospectively from January 2019 to December 2020. The patients were divided into "prenatal diagnosis and postnatal treatment integrated group" (n = 47) and "non-integrated group" (n = 69). RESULTS: The age of admission to the hospital and the age at surgery were earlier in the integrated group than in the non-integrated group (5.2 ± 7.2 days vs. 11.8 ± 8.0 days, P < 0.001; 11.9 ± 7.0 days vs. 16.5 ± 7.7 days, P = 0.001, respectively). The weight at surgery also was lower in the integrated group than in the non-integrated group (3.3 ± 0.4 kg vs. 3.6 ± 0.6 kg, P = 0.010). Longer postoperative recovery time was needed in the integrated group, with a median mechanical ventilation time of 97 h (interquartile range 51-259 h) vs. 69 h (29-168 h) (P = 0.030) and with intensive care unit time of 13.0 days (8.0-21.0 days) vs. 9.0 days (4.5-16.0 days) (P = 0.048). No significant difference was observed in the all-cause mortality (2.1 vs. 8.7%, P = 0.238), but it was significantly lower in the integrated group for transposition of the great arteries (0 vs. 18.8%, log rank P = 0.032). CONCLUSIONS: The prenatal diagnosis and postnatal treatment integrated model could significantly shorten the diagnosis and hospitalization interval of newborns, and surgical intervention could be performed with a lower risk of death, especially for transposition of the great arteries.
