Time to (A) first intubation and (B) for survivors, duration of intubation, according to carbamate ingested. There was little difference in time to intubation and duration of intubation between pesticides. The majority of patients were intubated between 0.5 and 5 h post-ingestion; nearly all were intubated within 48 h. Patients intubated after 48 h were typically intubated for worsening pneumonia and not for peripheral neuromuscular failure as noted after OP insecticide poisoning. Bars show the median (IQR) time.
