RESUMEN
OBJECTIVES: Inhaled nitric oxide (iNO) is a selective pulmonary vasodilator. It is expensive, frequently used, and not without risk. There is limited evidence supporting a standard approach to initiation and weaning. Our objective was to optimize the use of iNO in the cardiac ICU (CICU), PICU, and neonatal ICU (NICU) by establishing a standard approach to iNO utilization. DESIGN: A quality improvement study using a prospective cohort design with historical controls. SETTING: Four hundred seven-bed free standing quaternary care academic children's hospital. PATIENTS: All patients on iNO in the CICU, PICU, and NICU from January 1, 2017 to December 31, 2022. INTERVENTIONS: Unit-specific standard approaches to iNO initiation and weaning. MEASUREMENTS AND MAIN RESULTS: Sixteen thousand eighty-seven patients were admitted to the CICU, PICU, and NICU with 9343 in the pre-iNO pathway era (January 1, 2017 to June 30, 2020) and 6744 in the postpathway era (July 1, 2020 to December 31, 2022). We found a decrease in the percentage of CICU patients initiated on iNO from 17.8% to 11.8% after implementation of the iNO utilization pathway. We did not observe a change in iNO utilization between the pre- and post-iNO pathway eras in either the PICU or NICU. Based on these data, we estimate 564 total days of iNO (-24%) were saved over 24 months in association with the standard pathway in the CICU, with associated cost savings. CONCLUSIONS: Implementation of a standard pathway for iNO use was associated with a statistically discernible reduction in total iNO usage in the CICU, but no change in iNO use in the NICU and PICU. These differential results likely occurred because of multiple contextual factors in each care setting.

Specific pediatric populations have exhibited disparate responses to triiodothyronine (T3) repletion during and after cardiopulmonary bypass (CPB). Objective: To determine if T3 supplementation improves outcomes in children undergoing CPB. We searched randomized controlled trials (RCT) evaluating T3 supplementation in children aged 0-3 years undergoing CPB between 1/1/2000 and 1/31/2022. We calculated Hazard ratios (HR) for time to extubation (TTE), ICU length of stay (LOS), and hospital LOS. 5 RCTs met inclusion criteria with available patient-level data. Two were performed in United States (US) and 3 in Indonesia with 767 total subjects (range 29- 220). Median (IQR) age 4.1 (1.6, 8.0) months; female 43%; RACHS-1 scores: 1-1%; 2-55%; 3-27%; 4-13%; 5-0.1%; 6-3.9%; 54% of subjects in US vs 46% in Indonesia. Baseline TSH and T3 were lower in Indonesia (p < 0.001). No significant difference occurred in TTE between treatment groups overall [HR 1.09 (CI, 0.94-1.26)]. TTE numerically favored T3-treated patients aged 1-5 months [HR 1.24 (CI, 0.97-1.60)]. TTE HR for the Indonesian T3 group was 1.31 (CI, 1.04-1.65) vs. 0.95 (CI, 0.78-1.15) in US. The ICU LOS HR for the Indonesian T3 group was 1.19 vs. 0.89 in US (p = 0.046). There was a significant T3 effect on hospital LOS [HR 1.30 (CI, 1.01-1.67)] in Indonesia but not in US [HR 0.99 (CI, 0.78-1.23)]. T3 supplementation in children undergoing CPB is simple, inexpensive, and safe, showing benefit in resource-limited settings. Differences in effects between settings likely relate to depression in baseline thyroid function often associated with malnutrition.

Data comparing surgical systemic-to-pulmonary artery shunt and patent ductus arteriosus (PDA) stent as the initial palliation procedure for patients with pulmonary atresia with intact ventricular septum (PA-IVS) are limited. We sought to compare characteristics and outcomes in a multicenter cohort of patients with PA-IVS undergoing surgical shunts versus PDA stents. We retrospectively reviewed neonates with PA-IVS from 2009 to 2019 in 19 United States centers. Bivariate comparisons and multivariable logistic regression analysis were performed to determine the relationship between initial palliation strategy and outcomes including major adverse cardiovascular events (MACE): stroke, mechanical circulatory support, cardiac arrest, or death. 187 patients were included: 38 PDA stents and 149 surgical shunts. Baseline characteristics did not differ statistically between groups. Post-procedural MACE occurred in 4 patients (11%) with PDA stents versus 38 (26%) with surgical shunts, p = 0.079. Overall, the initial palliation strategy was not significantly associated with MACE (aOR:0.37; 95% CI,0.13-1.02). In patients with moderate-to-severe right ventricle hypoplasia, PDA stents were significantly associated with decreased odds of MACE (aOR:0.36; 95% CI,0.13-0.99). PDA stents were associated with lower vasoactive inotrope scores (median 0 versus 5, p < 0.001), greater likelihood to be extubated at the end of their procedure (37% versus 4%, p < 0.001), and shorter duration of mechanical ventilation (median 24 versus 96 h, p < 0.001). PDA stents were associated with significantly more unplanned reinterventions for hypoxemia compared to surgical shunts (42% vs. 20%, p = 0.009). In this multicenter study, neonates with PA-IVS who underwent PDA stenting received less vasoactive and ventilatory support postoperatively compared to those who had surgical shunts. Furthermore, patients with the most severe morphology had decreased odds of MACE.
