Between October 2017 and March 2018, a total of 396 children with AB were admitted to the La Paz University Children’s Hospital (Madrid, Spain). Of these 396 children, 102 with SAB were admitted to the PICU. These 102 patients (52% males, 48% females) with Mdn = 1 (IQR 0–4) month old were studied. Of 102 patients, 27% required IMV, 38% NIMV, and 93% HFOT either as an isolated therapy or following therapy de-escalation from IMV. IMV duration was 6.5 (IQR 3.3–9.0) days. PICU stay was 3.0 (IQR 2.0–4.0) days in nonintubated patients and 9.5 (IQR 6.2–11.0) days in IMV patients p <0.001.
