Introduction: The North Lisbon University Hospital Center was activated for referral of SARS-CoV-2 infected patients on the 11th March 2020. The aim of this study is to describe the experience at the Department of Pediatrics in the approach and the clinical outcomes of infected children.Material and Methods: A descriptive observational study was performed. Children and adolescents (0 to 18 years) with SARS-CoV-2 infection, diagnosed in the emergency room or admitted to the Department of Pediatrics between March 11th and June 18th, were included. Hospital records and Trace COVID-19 platform were reviewed and patient caregivers were interviewed to assess follow up.Results: Among 103 diagnosed children, 83% had a known previous contact with an infected patient, 43% presented fever and 42% presented respiratory symptoms. Ten percent had risk factors and 21% were aged under one year old. Ten percent were hospitalised, one needing intensive care, with paediatric inflammatory multisystem syndrome. Blood tests were performed in 9% and chest radiograph in 7%. No children required ventilation, antiviral therapy or underwent thoracic computed tomography scan. Eight percent of children returned to the emergency room and one child was hospitalised. The clinical outcome is known in 101 patients and is favourable in all.Discussion: Most children had an epidemiological link and little clinical repercussion, even during the first year of life. The expected mild severity in children justified the use of established clinical criteria and recommendations for similar conditions, regarding tests and hospitalizations. No antiviral treatments were given due to lack of evidence of its benefits.Conclusion: This strategy contributed to a low consumption of hospital resources and proved safe in this series.

Background and Aims Acute kidney injury (AKI) is a frequent complication in neonates and infants after congenital heart disease surgery, with great impact on morbidity and mortality. Peritoneal dialysis (PD) is the renal replacement therapy of choice, as it allows continuous gentle ultrafiltration with minimal impact on hemodynamic status. However, there is no standardized prescription. The present study aimed to describe our experience of using PD in the management of AKI after cardiac surgery in pediatric patients and the postoperative outcomes. Method Single-center cross-sectional study including 21 children undergoing cardiac surgery between 2017 and 2022, in a congenital heart disease reference center. Demographic and clinical data were collected from the electronic records. Results Of the 21 patients treated with PD, 11 were female. Mean age was 32 ± 45 days and median weight was 3.4 kg (IQR 0.5). All pregnancies had been full-term with a mean birth weight of 3.2 ± 0.3 kg. No congenital urinary tract anomalies had been previously documented. Previous history of AKI was present in 2 patients. Transposition of the great arteries was the most common surgical indication (52%). RACHS-1 score was ≥4 in 12 patients and median PRISM-IV score was 6.5% (IQR 6). Cardiopulmonary bypass was performed in 19 patients with a mean time of 181 ± 72 minutes and a mean aortic clamping time of 94 ± 29 minutes. All patients required inotropic support after cardiac surgery with ≥2 drugs, for 197 ± 136 hours. Median time with mechanical ventilation support was 126 hours (IQR 288) and median length of stay at the intensive care unit (ICU) was 9 days (IQR 15.3).The indications for PD initiation were anuria (66.7%), oliguria (23.8%) and fluid overload (9.5%). Median time between cardiac surgery and AKI diagnosis was 2.5 hours (IQR 8.8) and between AKI diagnosis and PD initiation was 1.8 hours (IQR 4.3). Median duration under dialysis was 2 days (IQR 3.5). Exchange volume of dialysate varied between 6 and 15 mL/kg at the beginning of PD. In 11 patients, this volume was progressively increased to a maximum of 60 mL/kg (minimum: 30 mL; maximum: 120 mL). Continuous veno-venous hemodiafiltration was required in 3 patients, mainly due to mechanical catheter dysfunction. Complications related to PD occurred in 5 patients: 1 patient developed peritonitis, 1 patient had mechanical catheter dysfunction and 3 patients had peri-catheter leak. Complete recovery of renal function was achieved in 14 patients. Longer time on PD was associated with lower weight before surgery (p = 0.04), longer time on mechanical ventilation and inotropic support (p < 0.001), and longer stay at the ICU (p < 0.001). Time on inotropic support could predict time on PD using a multiple regression model (adjusted R2 = 59%, p = 0.003), adjusted to cardiopulmonary bypass time, time on mechanical ventilation support and weight before surgery (adjusted ß = 0.7, p = 0.005). Eight patients died during hospitalization, due to multiorgan failure (38%), cardiogenic shock (38%), disseminated intravascular coagulation (13%) and septic shock (13%). Longer cardiopulmonary bypass time was associated with in-hospital mortality (149 ± 53 vs 235 ± 46, p = 0.004). Both the time between AKI diagnosis and PD initiation and the time on PD were not associated with in-hospital mortality. Conclusion Our study suggests that PD is a safe and effective dialysis modality in the management of post-cardiac surgery AKI in pediatric population. Early identification of high-risk infants is important to implement preventive measures.
