Development of MEES-scores, respiratory rates and SpO₂ of children receiving opioids or Esketamine (n = 2829). On-site arrival of emergency physician compared to handover in hospital. Only patients with complete data with regard to the category of interest were included, resulting in n = 156 (5.5%) for total MEES-scores, n = 257 (9.1%) for respiratory rates and n = 262 (9.3%) for SpO₂. Median NACA scores of patients with complete datasets: 4 (3–4) vs. 3 (3–4)
