Noteworthy articles in 2013 for cardiothoracic anesthesiologists.
In 2013, the field of cardiothoracic anesthesiology has continued to grow at the same astounding rate as in previous years. It has become increasingly difficult for practicing anesthesiologists to stay current on impactful publications related to our exciting subspecialty. ⋯ With the recent emphasis on teamwork spanning multiple medical specialties in the care for complex patients, the door has opened for our research to be presented in nontraditional, nonanesthesiology venues. In this review, we have selected a small sample of noteworthy contributions to the field of cardiothoracic and vascular anesthesiology published in 2013 with potential impact on our clinical practice.

ReviewPreoperative evaluation and perioperative management of right ventricular failure after left ventricular assist device implantation.
Right ventricular (RV) failure continues to be a major cause of morbidity and mortality after left ventricular assist device (LVAD) implantation. Preoperative evaluation of RV function with a variety of clinical, laboratory, echocardiographic, and hemodynamic variables is essential to ensure appropriate patient selection for LVAD therapy but remains imperfect. ⋯ Perioperative management of RV failure after LVAD implantation requires minimization of intraoperative RV ischemia, maintenance of appropriate filling pressure, supportive therapy with pulmonary vasodilators and inotropes, and surgical interventions such as RV assist devices in select cases. This article reviews the incidence of RV failure with LVAD implantation, preoperative predictors of RV failure, and perioperative management strategies.

ReviewAn updated review of sepsis for the anesthesiologist.
Severe sepsis and septic shock continue to be among of the leading causes of death in intensive care unit patients, carrying an estimated mortality rate between 30% and 50%. This article provides an evidence-based focused review of sepsis, including an update on management strategies based on the most recent guidelines published by the Surviving Sepsis Campaign.

ReviewModeling anesthetic developmental neurotoxicity using human stem cells.
Mounting preclinical evidence in rodents and nonhuman primates has demonstrated that prolonged exposure of developing animals to general anesthetics can induce widespread neuronal cell death followed by long-term memory and learning disabilities. In vitro experimental evidence from cultured neonatal animal neurons confirmed the in vivo findings. However, there is no direct clinical evidence of the detrimental effects of anesthetics in human fetuses, infants, or children. ⋯ Application of this high throughput in vitro stem cell neurogenesis approach is a major stride toward ensuring the safety of anesthetic agents in young children. This in vitro human model allows us to (1) screen the toxic effects of various anesthetics under controlled conditions during intense neuronal growth, (2) find the trigger for the anesthetic-induced catastrophic chain of toxic events, and (3) develop prevention strategies to avoid this toxic effect. In this article, we reviewed the current findings in anesthetic-induced neurotoxicity studies, specifically focusing on the in vitro human stem cell model.

ReviewThe distinct role of palliative care in the surgical intensive care unit.
Palliative care is expanding its role into the surgical intensive care units (SICU). Embedding palliative philosophies of care into SICUs has considerable potential to improve the quality of care, especially in complex patient care scenarios. This article will explore palliative care, identifying patients/families who benefit from palliative care services, how palliative care complements SICU care, and opportunities to integrate palliative care into the SICU. ⋯ Educational opportunities to improve end-of-life management skills are outlined. It is necessary to appreciate how traditional palliative and surgical cultures may influence the integration of palliative care into the SICU. Palliative care can provide a significant, "value added" contribution to the care of seriously ill SICU patients.
