Even though the Spanish pediatric ED providers' knowledge of the management of anaphylaxis is good, certain improvement areas are identified in both the identification and the management of these patients.

Background: This study aimed to define the existing barriers for early enteral nutrition (EEN) in critically ill children and to analyze the differences in nutrient supply, complications, and outcomes between EEN and late EN (LEN). Methods: This is a secondary analysis of a multicenter observational, prospective study including critically ill children receiving EN. Variables analyzed included demographic and anthropometric features, caloric and nutrient supply, outcomes, and complications according to the EN onset. Patients were classified into two groups according to the start of EN: 24-EEN vs EN started after 24 h (24-LEN) and . Results: Sixty-eight children were enrolled; 22.1% received 24-EEN, and 67.6% received 48-EEN. EN was most frequently delayed in patients older than 12 months, in patients with cardiac disease, and in those requiring mechanical ventilation (MV). Children in the 24-EEN group had shorter duration of MV compared with those in the 24-LEN group (P = 0.04). The 48-EEN group received a higher caloric intake (P = 0.04), reached the caloric target earlier (P < 0.01), and had lower incidence of constipation (P = 0.01) than the 48-LEN group. There was a positive correlation between the time required to reach the maximum caloric intake and the length of pediatric intensive care stay (r = 0.46; P < 0.01).

ObjectivesTo evaluate the performance of oral saliva swab (OSS) reverse transcription PCR (RT-PCR) compared with RT-PCR and antigen rapid diagnostic test (Ag-RDT) on nasopharyngeal swabs (NPS) for SARS-CoV-2 in children.DesignCross-sectional multicentre diagnostic study.SettingStudy nested in a prospective, observational cohort (EPICO-AEP) performed between February and March 2021 including 10 hospitals in Spain.PatientsChildren from 0 to 18 years with symptoms compatible with Covid-19 of ≤5 days of duration were included. Two NPS samples (Ag-RDT and RT-PCR) and one OSS sample for RT-PCR were collected.Main outcomePerformance of Ag-RDT and RT-PCR on NPS and RT-PCR on OSS sample for SARS-CoV-2.Results1174 children were included, aged 3.8 years (IQR 1.7–9.0); 73/1174 (6.2%) patients tested positive by at least one of the techniques. Sensitivity and specificity of OSS RT-PCR were 72.1% (95% CI 59.7 to 81.9) and 99.6% (95% CI 99 to 99.9), respectively, versus 61.8% (95% CI 49.1 to 73) and 99.9% (95% CI 99.4 to 100) for the Ag-RDT. Kappa index was 0.79 (95% CI 0.72 to 0.88) for OSS RT-PCR and 0.74 (95% CI 0.65 to 0.84) for Ag-RDT versus NPS RT-PCR.ConclusionsRT-PCR on the OSS sample is an accurate option for SARS-CoV-2 testing in children. A less intrusive technique for younger patients, who usually are tested frequently, might increase the number of patients tested.
