We present the management of a 15-year-old girl with acute myeloid leukemia who presented with massive hyperleukocytosis and neurological deficit due to intracerebral hemorrhage. Surgical intervention was considered but ultimately not undertaken because of the presence of massive hyperleukocytosis, thrombocytopenia, hypokalemia, and considerable discrepancy between the oxygen saturation values determined mechanically and by peripheral oximetry. Aggressive treatment of the hyperleukocytosis was immediately started, which improved the patient's overall condition and rendered surgical intervention unnecessary. This report shows that immediate treatment of massive hyperleukocytosis and critical interpretation of laboratory results in patients with hyperleukocytosis are warranted.

Waldenström's macroglobulinemia (WM) manifests as hyperviscosity syndrome. Cryoglobulinemia, which may increase blood viscosity or induce thrombosis in association with decreased body temperature, can occur in combination with WM. We describe the management of an 82-year-old woman with WM, hyperviscosity syndrome, and cryoglobulinemia who required open aortic valve replacement. Decreased body temperature in this patient was prevented during cardiopulmonary bypass by using a forced air warming system and normothermic cardioplegia with continuous warm blood cardioplegia perfusion.

Essential thrombocytosis (ET) is a rare disease with known thrombotic and bleeding complications. We encountered a patient with a diagnosis of longstanding Janus kinase-2 gene-negative ET on aspirin therapy presenting for labor epidural. Evaluation of platelet function with point-of-care analysis using Plateletworks in a community hospital setting allowed confirmation of adequate numbers of functional platelets to support safe epidural placement. The relevant issues of ET for anesthesia management with labor epidurals are discussed. Unique, relevant, and unexpected findings from the platelet function testing are presented.

The most common preventable cause of death after trauma is exsanguination due to uncontrolled hemorrhage. Traditionally, anterolateral emergency department thoracotomy is used for temporary control of noncompressible torso hemorrhage and to increase preload after trauma. Resuscitative endovascular balloon occlusion of the aorta is a minimally invasive technique that achieves similar goals. It is therefore imperative for the anesthesiologist to understand physiologic implications during resuscitative endovascular aortic occlusion and after balloon deflation. We report a case of a patient with significant pelvic and lower-extremity trauma who required acute resuscitative endovascular balloon occlusion of the aorta deployment, aggressive resuscitation, and extensive intraoperative hemorrhage control.

Antiphospholipid syndrome (APS) is an acquired thrombophilic disorder characterized by autoantibodies to cell membrane phospholipids. While altered coagulation can complicate end-stage liver disease, there are few reports describing the perioperative management for liver transplantation in recipients with a preexisting hypercoagulable disorder, such as APS. We present a patient with a history of APS, Budd-Chiari syndrome with cirrhosis, hepatopulmonary syndrome, and heparin-induced thrombocytopenia who underwent liver transplantation complicated by hepatic artery thrombosis. Management included postoperative anticoagulation with a factor Xa inhibitor and, after repeat transplantation, transition to long-term anticoagulation therapy with eventual recovery.

Women with complex congenital heart disease, such as those with single-ventricle physiology, are surviving into adulthood and becoming pregnant. Because of their complex physiology, common peripartum complications pose unique risks. We describe a patient with a single ventricle who underwent an external vascular conduit, nonfenestrated Fontan procedure in childhood and then presented during the postpartum period with extensive thrombosis in her lower extremity deep venous system and inferior vena cava. In this article, we will discuss single-ventricle physiology and the implications of pregnancy, anesthetic considerations, and data for maternal and fetal outcomes in this population.

Severe pulmonary hemorrhage occurred through the endotracheal tube during an emergency cesarean delivery. Intubation trauma was excluded with fiberoptic bronchoscopy. Episodes of hemoptysis continued for 48 hours. The patient was subsequently diagnosed with diffuse alveolar hemorrhage because of systemic lupus erythematosus. The diagnostic workup, successful management, and literature review are presented.

During a period of 1 month, 3 episodes of probable or actual venous air embolism occurred during hysteroscopic surgery. All patients developed the same symptoms of ventilatory and hemodynamic decompensation, beginning with a reduction in end-tidal carbon dioxide, arterial desaturation, and cyanosis on the upper trunk, and rapidly progressed to hypotension and 2 cardiac arrests. While entrainment of some air is common during hysteroscopy, life-threatening embolism is a rare but serious complication for which an anesthetist needs to be vigilant and prepared. If even a small drop in end-tidal carbon dioxide occurs, venous air embolism should be suspected and the operation should be discontinued.

Coagulopathy induced by trauma or cirrhosis is a well-recognized entity. Viscoelastic testing has been used in either condition for goal-directed transfusion and detection of fibrinolysis since conventional coagulation tests do not correlate with clinical risk of bleeding. Hemostatic resuscitation may not be adequate for a trauma patient with liver disease due to complex alterations in coagulation systems and occasionally require adjuvant therapy. We report a case of trauma-induced coagulopathy presenting as severe hyperfibrinolysis in a cirrhotic patient who was refractory to hemostatic resuscitation but was rapidly corrected by the administration of tranexamic acid and recombinant Factor VIIa.

Risk factors for intraoperative immediate-type hypersensitivity reactions may require allergological evaluation. We report the case of a hairdresser with a positive history of penicillin hypersensitivity and anaphylactic shock during previous general anesthesia, whose in vivo and in vitro allergy tests were positive for neuromuscular blocking agents, opioids, and midazolam. Immediate-type hypersensitivity reactions to antibiotics and professional exposure to hairdressing products might induce simultaneous cross-sensitization to multiple drugs that are commonly used during general anesthesia.
