Outline
A 20-month-old male infant was admitted to the department of infectious diseases of our hospital due to infectious fever and left cervical lymphadenitis. He received treatment with piperacillin sodium and tazobactam sodium for injection. After 7 consecutive days of medication (a total of 23 administrations) without adverse reactions, the infant suddenly developed symptoms of anaphylactic shock during the 24th administration, including irritability, incessant crying, pale complexion, cyanosis of the lips, cold extremities, and unmeasurable blood pressure. Medical staff immediately discontinued the infusion of piperacillin sodium and tazobactam sodium for injection and initiated rescue measures such as intramuscular injection of epinephrine. Eventually, the infant was successfully resuscitated. This case reminds medical personnel that the sensitization period of β-lactam antibiotics can last for several days or even months, which is concealed throughout the entire treatment course. The absence of adverse reactions during initial medication does not rule out subsequent risks. It is necessary to strengthen medical staff’s attention to medication monitoring during each administration to ensure the safety of pediatric medication.
