Outline
A 76 years old female patient was hospitalized twice for pulmonary infection and bronchiectasis with infection. During her first admission to the respiratory department for pulmonary infection, she received intravenous cefoperazone sodium/sulbactam sodium combined with bronchodilators for 11 days and was discharged following clinical improvement, with no documented adverse drug reactions (ADRs). During her second presentation to the emergency department for bronchiectasis exacerbation, the patient developed cyanosis and profuse sweating 13 minutes after intravenous cefoperazone/sulbactam administration. Despite successful resuscitation and subsequent transfer to the intensive care unit (ICU), emergency physicians failed to recognize this event as a suspected drug hypersensitivity reaction or document it in the medical records. After 11 days of meropenem therapy and symptomatic management in the ICU, she was transferred back to the respiratory department. Respiratory physicians initiated antibiotic de-escalation by readministering cefoperazone/sulbactam, which precipitated respiratory distress, profuse sweating and systemic discomfort within 19 minutes, followed by loss of consciousness and cardiopulmonary arrest. The patient died after 48 hours of unsuccessful resuscitation. This case serves as a reminder that the sensitization period for drugs can persist from several days to several months. The absence of ADRs with previous use does not entirely preclude the risk of subsequent administration. The recognition of hypersensitivity is critical, necessitating enhanced vigilance among healthcare professionals regarding ADRs. The documentation of ADRs and handover procedures during transfers between departments should not be overlooked to ensure medication safety.
