Aim: To investigate paediatric emergency room (ER) visits to evaluate the immediate health effects of COVID-19 pandemic restrictions on children., Methods: We retrospectively examined paediatric ER visits in the Helsinki University Hospital (HUH) district during the first wave of the pandemic (1 March to 31 May 2020), and a 2-month period immediately before and after. These periods were compared to the corresponding time periods in 2015-2019 ('reference period')., Results: The total number of ER visits decreased by 23.4% (mean 6474 during the reference period, 4960 during the pandemic period (incidence rate ratio [IRR] 0.75, 95% confidence interval 0.72-0.77; p < 0.001). This was due to a decrease in visits related to infectious diseases; visits due to surgical reasons did not decrease. The amount or proportion of patients triaged to the most urgent class (Emergency Severity Index 1) did not increase. Paediatric ER visits returned to baseline after lifting of restrictions., Conclusions: Although paediatric ER visits substantially decreased during the pandemic restrictions, children seen at the ER were not more severely ill. Our results do not indicate immediate detrimental health effects of pandemic control measures on children., (© 2022 The Authors.

Aim: Early extubation after cardiac surgery shortens paediatric intensive care unit (PICU) length of stay (LOS) and decreases complications from mechanical ventilation (MV). We explored the duration of MV in Scandinavian paediatric heart centres., Methods: We retrospectively reviewed the MV duration and PICU LOS of 696 children operated for atrial septal defect (ASD), ventricular septal defect (VSD), tetralogy of Fallot (TOF) or total cavopulmonary connection (TCPC) in four Scandinavian centres in 2015-2016. Neonates (n = 90) were included regardless of heart surgery type., Results: Patients with ASD were extubated at a median of 3.25 h (interquartile range [IQR] 2.00-4.83), followed by patients with TCPC (median 5.00 h, IQR 2.60-16.83), VSD (median 7.00 h, IQR 3.69-22.25) and TOF (median 18.08 h, IQR 6.00-41.38). Neonates were not extubated early (median 94.42 h, IQR 45.03-138.14). Although MV durations were reflected in PICU LOS, this was not as apparent among those extubated within 12 h. The Swedish centres had shortest MV durations and PICU LOS. Extubation failed in 24/696 (3.4%) of patients., Conclusion: Scandinavian paediatric heart centres differed in the duration of postoperative MV. Deferring extubation up to 12 h postoperatively did not markedly prolong PICU LOS., (© 2022 The Authors. Acta Paediatrica published by John Wiley & Sons Ltd on behalf of Foundation Acta Paediatrica.)
