Case Reports
Fentanyl-Induced Serotonin Syndrome 5 Days After Cessation of Serotonergic Agents: A Case Report.
A 21-year-old patient with intellectual disability was admitted for gastroenteritis due to serotonergic medication overdose, and subsequently developed serotonin syndrome. Her symptoms initially improved after the cessation of serotonergic medications, but worsened 5 days later after fentanyl administration during general anesthesia. On emergence, she had convulsions and was nonresponsive. ⋯ We suspect she had an exacerbation of her serotonin syndrome. She recovered successfully after supportive care. This case demonstrates that common medications used during anesthesia such as fentanyl can provoke serotonin syndrome, even several days after serotonergic drug discontinuation.

Anaphylaxis is a life-threatening, systemic, hypersensitivity reaction, manifested by urticaria, hypotension, and respiratory symptoms. Antigens that are cleared renally may have protracted exposure in patients with impaired renal function, resulting in prolonged and refractory anaphylactic shock. ⋯ The patient was treated with continuous, short-term, veno-venous hemodiafiltration. Initiating this therapy in patients with refractory anaphylactic shock and anuria due to an antigen that is excreted renally can expedite recovery.

Case Reports
Delayed Nonimmune Anaphylaxis Caused by Ropivacaine for Preoperative Nerve Blocks: A Case Report.
Ropivacaine is an amide local anesthetic with rare reports of anaphylaxis. To our knowledge, this is the first report of delayed nonimmune anaphylaxis induced by ropivacaine. ⋯ A basophil activation test (BAT) revealed ropivacaine as the causative agent. Notably, anaphylaxis can be caused by medications even hours after their administration, and all administered drugs should be suspected of potentially causing anaphylaxis.

Case Reports
Tranexamic Acid in Cardiac Surgery: A Case Report of an Infrequent Adverse Reaction to a Common Medication.
Life-threatening anaphylaxis to tranexamic acid (TXA) is rare but critical in cardiac surgery. A 76-year-old patient undergoing elective ascending aorta replacement developed severe anaphylactic shock shortly after anesthesia induction. ⋯ Guided by rotational thromboelastometry, hemostatic therapy led to a successful outcome with minimal postoperative bleeding. This report emphasizes the importance of drug risk awareness and strategies to mitigate excessive bleeding in cardiac surgery.
