    Introduction. Infant botulism (IB) is the most common form of human botulism in Argentina. Our objective was to describe the main aspects of diagnosis and management of patients with IB admitted to the pediatric intensive care unit (PICU). Methods. Observational, descriptive, and retrospective study. The PICU database with IB diagnosis in 2005-2020 period was used. Demographic variables, diagnostic methods, days of conventional mechanical ventilation (CMV), non-invasive ventilation (NIV), length of stay in the PICU and mortality upon hospital discharge were recorded. Results. In total, 21 patients with IB were recorded; 14 were male, their median age was 5 months (IQR: 2-6 m). Diagnosis was made by bioassay, and the toxin was identified in the serum of 12 patients. Only 1 patient did not require CMV; 1 patient had a tracheostomy; 18 patients received antibiotics; 5 received NIV. No patient was administered antitoxin and no patient died. The median length of stay in the hospital was 66 days (IQR: 42-76); in the PICU, 48 days (IQR: 29-78); and the median use of CMV, 37 days (IQR: 26-64). The delay until diagnostic confirmation was 15.8 ± 4.8 days. Conclusions. All patients were diagnosed using the bioassay technique, which resulted in a diagnostic delay that exceeds the recommended period for the administration of a specific treatment. No patient received a specific treatment. IB was related to a low mortality, but also to prolonged use o  MV and length of hospital stay, which were associated with cross infections and frequent antibiotic use.
