Human metapneumovirus infection in the cardiac paediatric ICU before and during COVID-19 pandemic: a retrospective cohort analysis.

INTRODUCTION: This study investigates the hygiene standards in the context of the COVID-19 pandemic and their impact on the perioperative incidence of human metapneumovirus as well as the typical symptom burden of human metapneumovirus-infected children with CHDs. MATERIALS AND METHODS: Between March 2018 and July 2021, all patients of a cardiac paediatric ICU of a German university hospital were included in this retrospective cohort analysis. RESULTS: A total of 589 patients with CHD were included in the analysis. Three hundred and fifty-two patients (148 females and 204 males) were admitted before the introduction of social distancing and face masks between March 2018 and 15 April 2020 (cohort A). Two hundred and thirty-seven patients (118 females and 119 males) were admitted after the introduction between April 16 and July 2021 (cohort B). In cohort A, human metapneumovirus was detected in 11 out of 352 patients (3.1%) during their stay at cardiac paediatric ICU. In cohort B, one patient out of 237 (0.4%) tested positive for human metapneumovirus. Patients who tested positive for human metapneumovirus stayed in cardiac paediatric ICU for a median of 17.5 days (range, 2-45 days). Patients without a detected human metapneumovirus infection stayed in the cardiac paediatric ICU for a median of 4 days (range, 0.5-114 days). Nine out of 12 (75%) human metapneumovirus-positive patients showed atelectasis. CONCLUSION: Perioperative human metapneumovirus infections prolong cardiac paediatric ICU stay in children with CHD. In affected patients, pulmonary impairment with typical symptoms appears. Under certain circumstances, a complication-rich perioperative infection with human metapneumovirus could be prevented in paediatric cardiac high-risk patients by prophylactic hygiene intervention.

[SARS-CoV-2 positive child-What to do if inhalation induction of anesthesia is unavoidable?] / SARS-CoV-2-positives Kind ­ Was tun bei unvermeidbarer inhalativer Narkoseeinleitung?

Induction of anesthesia by inhalation is very common in children due to difficult venous conditions and especially in uncooperative children. During the study on complications in the pediatric anesthesia in Europe (APRICOT study) including almost 30,000 patients, 48% of the children were induced by inhalation.Under the conditions of the corona pandemic, however, induction of anesthesia by inhalation represents an increased risk of infection due to the potential release of aerosols. Rapid sequence induction is recommended for anesthesia induction and definitive airway management for adults and children in the current pandemic situation.The present case demonstrates that there can be situations in children in which induction of anesthesia by inhalation is unavoidable and shows a potential procedure for reducing the risk of infection for the anesthesia personnel.
