ReviewMultisystem inflammatory syndrome in children during the coronavirus disease pandemic of 2019: a review of clinical features and acute phase management.
The current coronavirus disease of 2019 (COVID-19) pandemic has presented unique health challenges in the pediatric population. Compared to adults, the most significant change in viral disease manifestation is encompassed by the multisystem inflammatory syndrome in children (MIS-C). MIS-C is a new inflammatory syndrome which develops 2-4 weeks after COVID-19 exposure, with evidence suggesting it is a post-infectious immune reaction. ⋯ Most clinicians treated MIS-C with intravenous immunoglobulin, systemic steroids, and biological therapies. Overall mortality was low (2-3%) in all studies. Further research is needed to: understand if early intervention can prevent its progression; optimize its treatment; and improve outcomes of this new syndrome for the patients who develop MIS-C.

Meta AnalysisEffects of dexmedetomidine sedation for magnetic resonance imaging in children: a systematic review and meta-analysis.
Pediatric sedation is commonly required to obtain high-quality images in magnetic resonance imaging (MRI). We performed a systematic review and meta-analysis to assess the effects of dexmedetomidine sedation for MRI in children. ⋯ Dexmedetomidine sedation provided a similar sedation quality with a reduced incidence of desaturation events. However, the delayed onset and recovery times were drawbacks. The clinical significance of bradycardia is considered to be low. GRADE assessment revealed the quality of the evidence in this meta-analysis ranged from very low to moderate.

ReviewAerosol containment device for airway management of patients with COVID-19: a narrative review.
Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), is highly contagious. To protect healthcare workers from infection during airway management, some expert recommendations and guidelines recommended wearing P2/N95 masks, goggles or glasses, glove, face-shields, and gowns as standard personal protective equipment (PPE). Nevertheless, several simulation studies have suggested that the standard PPE may not fully protect healthcare workers. ⋯ Several simulation studies have indicated that "aerosol containment device" would make tracheal intubation more difficult. In addition, the device would prevent the spread of droplets from a patient, but may increase the risk of healthcare workers being exposed to a higher concentration of viral aerosols. Therefore, the current state of knowledge indicates that an "aerosol containment device" without vacuum mechanism has only limited efficacy in protecting healthcare workers from viral transmission.

ReviewRespiratory characteristics and related intraoperative ventilatory management for patients with COVID-19 pneumonia.
A substantial proportion of patients with coronavirus disease 19 (COVID-19) develop severe respiratory failure. Although the exact pathophysiology of severe COVID-19 pneumonia remains unknown and the characteristics of these patients are heterogeneous, the acute respiratory failure often fulfills criteria for acute respiratory distress syndrome (ARDS) and the clinical characteristics are also consistent with what is previously known about ARDS. Cohort studies also report distinctively high association between perioperative COVID-19 and postoperative mortality. In this special article, we review several publications on the pathophysiology of COVID-19, and discuss intraoperative ventilatory management for patients with COVID-19 based on the respiratory characteristics of COVID-19 pneumonia in light of the ongoing controversy of clinical phenotypes.

ReviewPreoperative assessment for scheduling surgery during the coronavirus disease pandemic.
On Mar 11, 2020, the World Health Organization declared coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), a pandemic. Because COVID-19 has a pre-symptomatic period of up to 2 weeks, SARS-CoV-2 infection has continued to spread. Some individuals with SARS-CoV-2 infection have a severe clinical course, while most individuals have mild or moderate symptoms. ⋯ Recently, the number of elective surgeries is gradually recovering from the effect of the COVID-19 pandemic, and hence, safe clinical practice and protocols to prevent SARS-CoV-2 transmission to medical staff should be established. This mini-review focuses on the preoperative assessment and decision with regard to scheduling surgery in elective and emergency cases during the COVID-19 pandemic. A standardized questionnaire and algorithm regarding COVID-19 should be used to assess surgical patients preoperatively as it increases the reproducibility and accuracy of the decision whether to proceed with surgery.
