RESUMO

This study evaluates the efficacy and safety of oral triiodothyronine on time to extubation for infants less than 5 months undergoing heart surgery in Indonesia, and primarily relates to patients in emerging programs with high malnutrition and mortality. In this randomized, double-blind, placebo-controlled trial, oral triiodothyronine (T3, Tetronine®) 1 µg/kg-body weight/dose or placebo (saccharum lactis) was administered via nasogastric tube every 6 h for 60 h to treatment group. A total of 120 patients were randomized into T3 (61 patients) and placebo (59 patients) groups. The majority of the patients had moderate to severe malnutrition (55.83%) with a high post-operative mortality rate of 23.3%. The T3 group showed significantly higher serum FT3 levels from 1 until 48 h post cross-clamp removal (p < 0.0001), lower incidence of low cardiac output syndrome at both 6 h (28 [45.9%] vs. 39 [66.1%] patients, p = 0.03, OR 2.3, 95% CI: 1.10-4.81) and 12 h after cross-clamp removal (25 [41.7%] vs. 36 [63.2%], p = 0.02, OR 2.40, 95% CI: 1.14-5.05). Although not statistically significant, the treatment group had shorter median (IQR) intubation time (2.59 [1.25-5.24] vs. 3.77 [1.28-6.64] days, p = 0.16, HR 1.36, 95% CI: 0.88-2.09)] and lower mortality (10 [16.4%] vs. 18 [30.5%], p = 0.07]. Patients with Aristotle score < 10.0 (low risk) receiving T3 had faster extubation than placebo patients (p = 0.021, HR of 1.90, 95% CI: 1.10-3.28) and were significantly less likely to require CPR or experience infection (p = 0.027, OR 8.56, 95% CI:0.99-73.9 and p = 0.022, OR 4.09 95% CI: 1.16-14.4, respectively). Oral T3 supplementation reduced overall incidence of low cardiac output syndrome and significantly reduced the time to extubation in low-risk patients. Therefore, prophylactic oral T3 administration may be beneficial in these patients.Trial Registration: ClinicalTrials.gov NCT02222532.

RESUMO

OBJECTIVES: Acute pulmonary hypertension and pulmonary hypertensive crisis may result in adverse clinical outcomes if unsuccessfully treated. Inhaled nitric oxide has long been considered as the standard pharmacotherapy for acute pulmonary hypertension, but lack of feasibility in some settings and evidences challenging its benefits lead to the use of alternative treatment, amongst which is nitroglycerin inhalation. The purpose of this review article is to discuss available data on the use of nitroglycerin inhalation for acute treatment of pulmonary hypertension in children with CHD and its potential benefit in post-operative setting. DATA SOURCES: Literatures included in this review were acquired by searching in PubMed online database. Keywords used were "Pulmonary Hypertension", "Congenital heart defects", "Pediatrics", "Inhaled nitroglycerin", and its synonyms. STUDY SELECTION: Title and abstract were screened to select relevant literatures including the three paediatric clinical trials on nitroglycerin inhalation. Critical appraisal of the clinical trials was then done using the University of Oxford Centre of Evidence-Based Medicine Critical Appraisal Tools. CONCLUSIONS: Paediatric studies showed the benefit of nitroglycerin inhalation in uncorrected cases of CHD during catheterisation procedures. Until recently, there have been no studies conducted in paediatric post-operative CHD cases. Further study is required to provide evidence for inhaled nitroglycerin use in this setting including the appropriate dosing and potential side effects with repeated administration.

RESUMO

BACKGROUND: The impact of the COVID-19 pandemic on paediatric populations varied between high-income countries (HICs) versus low-income to middle-income countries (LMICs). We sought to investigate differences in paediatric clinical outcomes and identify factors contributing to disparity between countries. METHODS: The International Severe Acute Respiratory and Emerging Infections Consortium (ISARIC) COVID-19 database was queried to include children under 19 years of age admitted to hospital from January 2020 to April 2021 with suspected or confirmed COVID-19 diagnosis. Univariate and multivariable analysis of contributing factors for mortality were assessed by country group (HICs vs LMICs) as defined by the World Bank criteria. RESULTS: A total of 12 860 children (3819 from 21 HICs and 9041 from 15 LMICs) participated in this study. Of these, 8961 were laboratory-confirmed and 3899 suspected COVID-19 cases. About 52% of LMICs children were black, and more than 40% were infants and adolescent. Overall in-hospital mortality rate (95% CI) was 3.3% [=(3.0% to 3.6%), higher in LMICs than HICs (4.0% (3.6% to 4.4%) and 1.7% (1.3% to 2.1%), respectively). There were significant differences between country income groups in intervention profile, with higher use of antibiotics, antivirals, corticosteroids, prone positioning, high flow nasal cannula, non-invasive and invasive mechanical ventilation in HICs. Out of the 439 mechanically ventilated children, mortality occurred in 106 (24.1%) subjects, which was higher in LMICs than HICs (89 (43.6%) vs 17 (7.2%) respectively). Pre-existing infectious comorbidities (tuberculosis and HIV) and some complications (bacterial pneumonia, acute respiratory distress syndrome and myocarditis) were significantly higher in LMICs compared with HICs. On multivariable analysis, LMIC as country income group was associated with increased risk of mortality (adjusted HR 4.73 (3.16 to 7.10)). CONCLUSION: Mortality and morbidities were higher in LMICs than HICs, and it may be attributable to differences in patient demographics, complications and access to supportive and treatment modalities.
