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.

Recently, denervation therapies have drawn attention as a promising treatment, and cooled radiofrequency has been proposed as the best option to capture most of the genicular nerves. We present a rare case of synovial knee fistula after radiofrequency and its management. ⋯ One week later, the fistula was closed, and 14 months later, the procedure was repeated without complications. Genicular radiofrequency ablation is an emerging technique, and providers should be aware of the reported complications to counsel patients and manage potential risks appropriately.

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
Posterior Reversible Encephalopathy Syndrome and Eclampsia in the Setting of Magnesium Toxicity: A Case Report.
Posterior reversible encephalopathy syndrome (PRES) is a rare neurologic condition and a feared complication of eclampsia. It is evidenced by acute neurologic dysfunction secondary to cerebral edema and is typically reversible in nature. ⋯ We present a case wherein a 24-year-old parturient developed PRES and eclampsia in the setting of symptomatic hypermagnesemia, requiring management with lorazepam after seizures developed. Here we detail her clinical course, including the unique challenges of treating eclampsia and PRES in the setting of magnesium toxicity.
