RESUMO

Nutrition provision for children with heart disease supported with extracorporeal membrane oxygenation (ECMO) involves nuanced decision making. We examined nutrition provision while on ECMO in the CICU and the relationship between energy and protein adequacy and end organ function as assessed by pediatric sequential organ failure assessment (pSOFA) scores in children with heart disease supported with ECMO. Children (≤ 21 years-old) with congenital or acquired heart disease who received ECMO in the cardiac intensive care unit were included. There were 259 ECMO runs in 252 patients over an 8-year study period (2013-2020). Median energy delivery and adequacy were 26.1 [8.4, 45.9] kcal/kg/day and 58.3 [19.8, 94.6]%, respectively. Median protein delivery and adequacy were 0.98 [0.36, 1.64] g/kg/day and 35.7 [13.4, 60.3]%, respectively. pSOFA increased by a median of four points during the ECMO run. Change in pSOFA score was not associated with energy or protein adequacy (p = 0.46 and p = 0.72, respectively). Higher energy and protein adequacy-from parenteral nutrition-correlated with increased hospital-acquired infections (HAIs, p = 0.031 and p = 0.003, respectively). Achieving nutritional adequacy was dependent on the use of parenteral nutrition. Similar clinical outcomes with regard to end organ function but with an increased incidence of HAIs suggests the need to explore the role of optimal enteral nutrition delivery on ECMO.

RESUMO

BACKGROUND: Interventional therapies for severe pulmonary arterial hypertension (PAH) can provide right ventricular (RV) decompression and preserve cardiac output. Transcatheter stent placement in a residual ductus arteriosus (PDA) is one potentially effective option in critically ill infants and young children with PAH. We sought to assess recovery of RV function by echocardiographic strain in infants and young children following PDA stenting for acute PAH. METHODS: Retrospective review of patients < 2 years old who underwent PDA stenting for acute PAH. Clinical data were abstracted from the electronic medical record. RV strain (both total and free wall components) was assessed from echocardiographic images at baseline and 3, 6, and 12 months post-intervention, as well as at last echocardiogram. RESULTS: Nine patients underwent attempted ductal stenting for PAH. The median age at intervention was 38 days and median weight 3.7 kg. One-third (3of 9) of patients had PAH associated with a congenital diaphragmatic hernia. PDA stents were successfully deployed in eight patients. Mean RV total strain was - 14.9 ± 5.6% at baseline and improved to - 23.8 ± 2.2% at 6 months post-procedure (p < 0.001). Mean free wall RV strain was - 19.5 ± 5.4% at baseline and improved to - 27.7 ± 4.1% at 6 months (p = 0.002). Five patients survived to discharge, and four patients survived 1 year post-discharge. CONCLUSION: PDA stenting for severe, acute PAH can improve RV function as assessed by strain echocardiography. The quantitative improvement is more prominent in the first 6 months post-procedure and stabilizes thereafter.

RESUMO

Hypertension is a known complication of pediatric heart transplantation. We sought to identify factors associated with anti-hypertensive use in pediatric heart transplant recipients immediately post-transplant and oral anti-hypertensive use at discharge and 1-year post-transplant. Retrospective chart review was conducted of patients ≤18 years who underwent heart transplantation at two major heart transplant centers between August 1, 2009 and December 31, 2017 with ≥1-year follow-up. Exclusion criteria included re-transplant, multi-organ recipients, survival <1 year, and comorbidities associated with hypertension. Anti-hypertensive use was recorded during initial ICU stay, at discharge, and 1-year post-transplant. Univariate and multivariate analyses determined associations of demographic and diagnostic factors and need for anti-hypertensives. There were 188 patients that met inclusion criteria. Anti-hypertensive infusions were required in the ICU post-transplant in 46 patients (24.5%) for a median of 3 days (1-21 days). Oral anti-hypertensives were required in 58 patients (30.9%) at discharge and 1-year post-transplant. Anti-hypertensive infusion in the ICU post-transplant was associated with donor-to-recipient weight ratio. Oral anti-hypertensive use at discharge was associated with weight ratio and pretransplant VAD use, and at 1-year, post-transplant was associated with age at transplant, steroid use at discharge, and oral anti-hypertensive use at discharge. Hypertension is common immediately following and 1-year post-transplant. Weight ratio was the only independent predictor of anti-hypertensive use in the early post-transplant period, whereas VAD use was also associated with anti-hypertensive use at discharge. Anti-hypertensive use 1-year post-transplant was not associated with those factors, but rather with age at transplant and steroid use.

RESUMO

Children with congenital heart disease often require admission to the cardiac intensive care unit at some point in their lives, either after elective surgical or catheter-based procedures or during times of acute critical illness. Meeting both the macronutrient and micronutrient needs of children in the cardiac intensive care unit requires complex decision-making when considering gastrointestinal perfusion, vasoactive support, and fluid balance goals. Although nutrition guidelines exist for critically ill children, these cannot always be extrapolated to children with congenital heart disease. Children with congenital heart disease may also suffer unique circumstances, such as chylothoraces, heart failure, and the need for mechanical circulatory support, which greatly impact nutrition delivery. Guidelines for neonates and children with heart disease continue to be developed. We provide a synthesized narrative review of current literature and considerations for nutrition evaluation and management of critically ill children with congenital heart disease.

RESUMO

Cardiac surgical patients requiring extracorporeal membrane oxygenation (ECMO) are at increased risk for hemorrhage due to necessary anticoagulation, in-situ cannulas, and disturbed hemostasis. We performed a retrospective, cross-sectional study of patients 0-18 years old in our cardiac intensive care unit (CICU) cannulated to ECMO within 48 h of cardiopulmonary bypass. The 69 patients included in the study were divided into three analysis groups based on serial chest tube output per hour: no bleeding (NB) on admission to the CICU (21/69, 30%), bleeding stopped (BS) with medical management (26/69, 38%), bleeding requiring emergent mediastinal exploration (BME) (22/69, 32%). The NB group had a more favorable coagulation profile upon admission to the CICU (PTT 53 s NB, 105 s BS, 83 s BME p < 0.001, ACT 169 s NB, 225 s BS, 211 s BME, p =0.013). Only chest tube output during the first three postcannulation hours remained associated with the need for mediastinal exploration by multivariable analysis. An average chest-tube output of 11.6 mL/kg/h during the first three hours had the highest percentage of patients classified correctly (84%) for requiring mediastinal exploration during their ECMO run (sensitivity 91%, specificity 81%).
