ABSTRACT
SARS-CoV-2 infection in children is usually asymptomatic/mild. However, some patients may develop critical forms. We aimed to describe characteristics and evaluate the factors associated to in-hospital mortality of patients with critical COVID-19/MIS-C in the Amazonian region. This multicenter prospective cohort included critically ill children (1 mo-18 years old), with confirmed COVID-19/MIS-C admitted to 3 tertiary Pediatric Intensive Care Units (PICU) in the Brazilian Amazon, between April/2020 and May/2023. The main outcome was in-hospital mortality and were evaluated using a multivariable Cox proportional regression. We adjusted the model for pediatric risk of mortality score version IV (PRISMIV) score and age/comorbidity. 266 patients were assessed with 187 in the severe COVID-19 group, 79 included in the MIS-C group. In the severe COVID-19 group 108 (57.8%) were male, median age was 23 months, 95 (50.8%) were up to 2 years of age. Forty-two (22.5%) patients in this group died during follow-up in a median time of 11 days (IQR, 2-28). In the MIS-C group, 56 (70.9%) were male, median age was 23 months and median follow-up was 162 days (range, 3-202). Death occurred in 17 (21.5%) patients with a median death time of 7 (IQR, 4-13) days. The mortality was associated with higher levels of Vasoactive Inotropic-Score (VIS), presence of acute respiratory distress syndrome (ARDS), higher levels of Erythrocyte Sedimentation Rate, (ESR) and thrombocytopenia. Critically ill patients with severe COVID-19 and MIS-C from the Brazilian Amazon showed a high mortality rate, within 12 days of hospitalization.

This case report describes the long-term behavioral and cognitive alterations in a critically ill pediatric patient submitted to a ketamine sedation and analgesia protocol for 7 consecutive days in a pediatric intensive care unit. The infant exhibited withdrawal syndrome in the early withdrawal period, as measured using the Withdrawal Assessment Tool-1 (WAT-1). In the days following ketamine withdrawal, behavioral, motor, and cognitive impairment was observed, even after hospital discharge. At 20 days after admission to hospital, the infant still displayed language deficits compatible with the at-risk category for the appropriate age group on the development assessment (Denver-II Developmental Screening Test). The infant's mother reported that these impairments were not present before ketamine sedation. We therefore suggest that prolonged ketamine use may have contributed to the long-lasting behavioral and cognitive impairments observed in the critically ill infant. These adverse effects may be attributable to ketamine's pharmacological mechanism of action, by which the N-methyl-D-aspartate receptor-the central nervous system excitatory receptor responsible for memory and learning domains-is blockaded, disrupting long-term potentiation events. Our case highlights the need for clinical evaluation of ketamine agents and their associated risks in intensive care units to better clarify appropriate sedative and analgesic agents during neurodevelopmental periods of life.
ABSTRACT
We described the characteristics of 11 children with pediatric multisystem inflammatory syndrome-temporally associated with SARS-CoV-2. The main clinical indications for hospital admission were vasogenic toxic shock (n = 2), Kawasaki disease (n = 4), and Kawasaki disease shock syndrome (n = 5). The echocardiography findings were abnormal in 63% of cases. All patients had 2 or more organ dysfunctions, and the mortality rate was 18%.
