A & A case reports

While an abundance of literature exists describing adverse reactions to vancomycin (eg, nausea, vomiting, red man syndrome, acute kidney injury), there is scarce evidence demonstrating vancomycin anaphylactic reactions requiring cardiopulmonary resuscitation. We report a case of a patient who had 2 separate preoperative episodes of cardiac arrest following vancomycin that occurred 4 weeks apart. Both episodes of anaphylaxis required cardiopulmonary resuscitation, which led to a successful patient outcome. We discuss identification and treatment of vancomycin-induced anaphylaxis.

Malignant Hyperthermia in a Morbidly Obese Patient Depletes Community Dantrolene Resources: A Case Report.
During resection of a duodenal carcinoid tumor, a 28-year-old morbidly obese woman developed suspected malignant hyperthermia. This hypermetabolic state posed a diagnostic challenge given the similar intraoperative presentation of carcinoid crisis and malignant hyperthermia. ⋯ Current dantrolene dosing recommendations are based on actual body weight despite a paucity of literature in obese patients. We speculate that the prolonged need for dantrolene redosing was from the continuous release of the volatile anesthetic from the patient's adipose tissue.

Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) is a novel airway technique that utilizes high-flow humidified nasal oxygen. It can extend apnea time and maintain oxygen saturation. ⋯ Intravenous sedation resulted in hypoventilation close to apnea. THRIVE maintained oxygen saturation for 40 minutes until transient desaturation developed after complete airway obstruction.

Early diagnosis of aortic dissection is important to reduce mortality, with surgical management representing standard treatment. Current methods of diagnosing type A aortic dissection include computed tomography angiography (CTA), magnetic resonance imaging, catheter-based arteriography, and transesophageal echocardiography. ⋯ We present a case of a patient who was diagnosed with type A aortic dissection by CTA, but was found to not have an aortic dissection by transesophageal echocardiography under general anesthesia, preventing an unnecessary sternotomy. The echocardiographic findings suggested CTA artifact.
