ReviewThe pregnant patient with congenital heart disease.
Advances in the surgical palliation and correction of congenital heart lesions have improved survival and increased the number of patients living into adulthood. Although pregnancy outcomes will be favorable for most patients with congenital heart disease, the cardiovascular challenges associated with pregnancy and delivery are best managed with a multidisciplinary approach during the puerperium. This review addresses the prevalence, physiology, risk assessment, peripartum complications, and anesthetic management of the pregnant patient with underlying congenital heart disease.

Case ReportsAnterior mediastinal mass biopsy and resection: anesthetic techniques and perioperative concerns.
The perioperative management of the patient with an anterior mediastinal mass (AMM) is viewed as one of the more challenging anesthetic endeavors. Diligent preoperative planning is essential and often involves imaging studies using multiple modalities, pulmonary function assessment, and minimally invasive biopsy for tissue diagnosis prior to arriving in the operating room. Anesthetic induction, often without major risks in most patients, can be catastrophic in AMM patients, with possible complications that include complete airway obstruction and cardiovascular collapse. ⋯ This review will explore the following: (1) the use of MAC/sedation for AMM biopsy, (2) methods of safely securing the airway in patients undergoing definitive mass resection via median sternotomy, (3) current opinions regarding the need for preoperative pulmonary function testing in these patients, (4) current opinions regarding the need for and timing of cardiopulmonary bypass in these cases, (5) the use of intraoperative transesophageal echocardiography during resection, and (6) the characteristics of mediastinal germ-cell tumors with sarcomatous conversion. Though multiple anesthetic methods have been proposed for the management of patients undergoing tissue biopsy and resection of an AMM, this case report presents 2 successful anesthetic options for 2 distinct surgical procedures. In every instance, the anesthetic management options must be tailored to the unique physiological needs of the patient presenting for surgery.

ReviewTrauma and thrombelastography: how changes in the understanding of coagulopathy, testing, and hospital systems have changed one group's practice.
Bleeding disorders associated with trauma are of paramount importance when dealing with the acutely injured individual. Statistically, up to 40% of trauma related deaths are assumed to be related to hemorrhage. ⋯ Over time, newer theories have been developed to help the clinician begin to understand the etiology and treatment of this process. The purpose of this paper is to review current literature and explain how these new concepts helped change practice in an urban, academic, Level One Trauma Center.

ReviewPerioperative management of peripheral vascular trauma.
Peripheral vascular trauma is not uncommon in the civilian setting, and it can be uniquely challenging because of the limited time during which intervention can salvage an ischemic extremity. Injuries can be from a blunt or penetrating mechanism, and these injuries can be isolated or can be in the setting of a complex multisystem trauma. The intent of this review is to discuss the perioperative management of peripheral vascular trauma with an emphasis of predicting, preventing, and managing common postoperative complications.

The US military experience with fresh whole blood during the conflicts in Iraq and Afghanistan.
Since its introduction in the early part of the last century, fresh whole blood (FWB) has been used by the US military as a battlefield expedient resuscitation method, even after the development of component therapy in the 1960s. In the recent conflicts in Iraq and Afghanistan, FWB was used once more, often collected in the setting of a walking blood bank (WBB). ⋯ Despite efforts by the US military to improve the effectiveness and safety of FWB through a series of widely published guidelines, transfusion transmitted infections (TTI) remain a vexing challenge. These experiences in Iraq and Afghanistan will help inform a larger discussion regarding the reintroduction of FWB in civilian trauma resuscitation.
