Adverse drug reactions (ADRs) were prospectively studied in critically
ill infants and children. Seventy-six ADRs were reported in 63 patien
ts out of a study group of 899 patients. The majority of the ADRs were
mild (49), although 19 were of moderate severity and 8 were severe. T
hirty-five ADRs required treatment or alteration in treatment. Midazol
am, morphine, salbutamol, vecuronium, hydrocortisone and theophylline
were the drugs most likely to cause an ADR. One-third of the ADRs were
due to drugs used outside their product licence. The majority of the
ADRs were reported by nurses (36) and pharmacists (30). We believe tha
t it is possible to prospectively study drug toxicity in critically il
l infants and children.
