Background Tracheostomy is one of the most common surgical procedures performed on ventilated COVID-19 patients yet the appropriate timing for operating is controversial. Objectives Assessing the effect of early tracheostomy on mortality and decannulation; elucidating changes in ventilation parameters, vasopressors and sedatives dosages immediately following the procedure. Methods A retrospective cohort of 38 ventilated COVID-19 patients, 19 of them (50%) underwent tracheostomy within 7 days of intubation (early tracheostomy group) and the rest underwent tracheostomy after 8 days or more (late tracheostomy group). Results Decannulation rates were significantly higher while mortality rates were non-significantly lower in the early tracheostomy group compared with the late tracheostomy group (58% vs 21% p < 0.05; 42% vs 74% p = 0.1, respectively). Tidal volume increased (446 ml vs 483 ml; p = 0.02) while PEEP (13 cmH 2 0 vs 11.6 cmH 2 O, p = 0.04) decreased at the immediate time following the procedure. No staff member participating in the procedures was infected with SARS-CoV-2 virus. Conclusion Early tracheostomy might offer improved outcomes with higher decannulation rates and lower mortality rates in ventilated COVID-19 patients, yet larger scale studies are needed. Most likely, early exposure to COVID-19 patients with appropriate personal protective equipment during open tracheostomy does not put the surgical team at risk.

Thiamine is an essential component of cellular metabolism and its deficiency results in potentially life-threatening events and profound lactic acidosis through anaerobic metabolism. Acute decompensation in thiamine-deficient patients may manifest as neurologic or cardiovascular changes, with severe lactic acidosis as the presenting symptom. We describe two hematological pediatric patients with thiamine deficiency and hemodynamic instability who improved following thiamine supplements. Thiamine levels were inversely proportional to lactic acidosis; specifically, lower thiamine levels were related to higher lactate levels. We recommend that children with hematological malignancies admitted to a pediatric intensive care unit with low blood pressure and lactic acidosis should be considered for thiamine-level screening and receive supplementation accordingly.

Background: Patients with congenital heart disease have higher prevalence of thyroid dysfunction due to embryonic and genetic coexistence. Marked changes in cardiac function occur secondary to alternations in thyroid hormone levels. Cardiac catheterizations or cardiac surgeries with cardiopulmonary bypass can cause abnormalities in the circulating hormones, in the absence of primary thyroid disease. Therefore, monitoring of thyroid function should be routinely performed in children with congenital heart disease. Thyroid hormone supplementation has been postulated as a possible therapeutic option; however, the therapeutic decisions should be made based on individual circumstances, symptoms, and the severity of the thyroid dysfunction. Objectives: To describe the correlation between congenital heart disease in children and thyroid dysfunction and the debate on monitoring, intervention, and treatment. Methods: PubMed, Clinical Key, and the Cochrane Library were searched using keywords relevant to congenital heart disease/surgery, cardiopulmonary bypass, thyroid hormones, sick euthyroid syndrome, and cardiac catheterization. Studies were limited to the English language and to children 0 to 18 years old. Studies in adults with important findings were reviewed as well. All clinical studies believed to have relevance were considered. All relevant studies were reviewed, and the most pertinent data were incorporated in this review. Conclusion: There is lack of significant evidence concerning treatment for thyroid dysfunction in children with a congenital cardiac diagnosis. Adequately powered studies are needed before a uniform recommendation about treatment can be made.

One of the major challenges for healthcare systems during the Coronavirus-2019 (COVID-19) pandemic was the inability to successfully predict which patients would require mechanical ventilation (MV). Angiotensin-Converting Enzyme 2 (ACE2) and TransMembrane Protease Serine S1 member 2 (TMPRSS2) are enzymes that play crucial roles in SARS-CoV-2 entry into human host cells. However, their predictive value as biomarkers for risk stratification for respiratory deterioration requiring MV has not yet been evaluated. We aimed to evaluate whether serum ACE2 and TMPRSS2 levels are associated with adverse outcomes in COVID-19, and specifically the need for MV. COVID-19 patients admitted to an Israeli tertiary medical center between March--November 2020, were included. Serum samples were obtained shortly after admission (day 0) and again following one week of admission (day 7). ACE2 and TMPRSS2 concentrations were measured with ELISA. Of 72 patients included, 30 (41.6%) ultimately required MV. Serum ACE2 concentrations >7.8 ng/mL at admission were significantly associated with the need for MV (p = 0.036), inotropic support, and renal replacement therapy. In multivariate logistic regression analysis, elevated ACE2 at admission was associated with the need for MV (OR = 7.49; p = 0.014). To conclude, elevated serum ACE2 concentration early in COVID-19 illness correlates with respiratory failure necessitating mechanical ventilation. We suggest that measuring serum ACE2 at admission may be useful for predicting the risk of severe disease.

Background: Acute pain and anxiety management during pediatric burn dressing change is very challenging. There are limited data regarding feasibility and safety of sedation administration by nonanesthesiologists. We sought to describe the implementation of a sedation protocol for pediatric residents during burn dressing changes in the pediatric ward.Methods: An analgesia and sedation protocol was designed and implemented in the pediatric wards in 2015. Retrospective data were collected on all children who were sedated by pediatric residents for burns in the pediatric wards over a 4-year period in our hospital. Demographics, burn characteristics, and data regarding adverse events were collected from patients' electronic medical records. The main outcomes were successful procedure completion and safety.Results: During the study period, 1130 sedations were performed in 272 patients by pediatric residents. The median age was 2.5 years (IQR 1.3-9.1). Sixty-two percent (695/1130) of the patients were male. The majority of the burns (84%, 955/1130) were <20%, and the majority of the patients (91%, 1030/1130) had an ASA (American Society of Anesthesiologists) score of 1. The incidence rate of adverse events was 4.3% (49/1130) and 1.3% (15/1130) for serious adverse events . There were no statistically significant differences in gender, age, ASA, or burn degree between patients with or without adverse events. Conclusions:We designed and implemented an analgesia and sedation protocol for pediatric residents to be applied in patients during burn dressing change. The implemented protocol in the pediatric wards was found to be feasible and with a low incidence of adverse events.
