Case Report: Anaphylactic shock induced by cefoperazone sodium and sulbactam sodium for injection.

Rationale: Cefoperazone-sulbactam is a widely used antibiotic in clinical practice, and anaphylactic shock is a severe adverse drug reaction. Previous literature has rarely reported cases of anaphylactic shock induced by cefoperazone-sulbactam. Patient concerns: A 38-year-old male patient who underwent surgery for cerebral hemorrhage developed fever, with considerations of pulmonary and urinary tract infections. Following the administration of injectable cefoperazone-sulbactam, he experienced anaphylactic shock. Diagnosis: Anaphylactic shock was suspected to be caused by injectable cefoperazone-sulbactam. Interventions: The patient was administered a subcutaneous injection of 1 mg epinephrine, followed by continuous infusion of 10 mg norepinephrine in 45 mL of 5% glucose solution via a pump. Additionally, assisted ventilation with a respirator and fluid resuscitation were provided. Outcome: The patient was discharged with improved symptoms. Lessons: To prevent serious adverse reactions, it is essential to strictly adhere to indications and contraindications to avoid misuse and minimize the occurrence of adverse effects. Prior to medication administration, a thorough inquiry into the patient's drug allergy history and family history should be conducted.
