Randomized Controlled Trial
Erythropoietin and Protection of Renal Function in Cardiac Surgery (the EPRICS Trial).
To date, there are no known methods for preventing acute kidney injury after cardiac surgery. Increasing evidence suggests that erythropoietin has renal antiapoptotic and tissue protective effects. However, recent human studies have shown conflicting results. The authors aimed to study the effect of a single high-dose erythropoietin preoperatively on renal function after coronary artery bypass grafting in patients with preoperative impaired renal function. ⋯ Intravenous administration of a single high-dose (400 IU/kg) erythropoietin did not have a renal protective effect on patients with reduced kidney function undergoing coronary artery bypass surgery.

Multicenter Study
Predictors of Functional Outcome after Intraoperative Cardiac Arrest.
Few outcome data are available about intraoperative cardiac arrest (IOCA). The authors studied 90-day functional outcomes and their determinants in patients admitted to the intensive care unit after IOCA. ⋯ By day 90, 45% of IOCA survivors had good functional outcomes. The main outcome predictors were directly related to IOCA occurrence and postcardiac arrest syndrome; they suggest that the intensive care unit management of postcardiac arrest syndrome may be amenable to improvement.

Various experimental studies in animals have shown that general anaesthetics are potentially toxic to the developing brain. By inducing apoptosis or interfering with neurogenesis, anaesthetic exposure during a critical period of neuronal development can have significant impact on neurocognitive function later in life. It remains controversial whether these experimental results can be transferred to human beings and this is under intensive scientific evaluation. ⋯ Anaesthesia is not an end in itself, but necessary to facilitate surgical procedures. There is evidence that maintaining physiological conditions is important for the overall outcome following anaesthesia and surgery. Until proven otherwise, it can be recommended to keep anaesthesia and surgery as short as possible, to use short-acting drugs and/or a combination of general anaesthesia and multimodal pain therapy including systemic analgesics, and local or regional anaesthesia, to reduce the overall drug dosage.

Arterial Blood Pressure and Neurological Outcome After Resuscitation From Cardiac Arrest.
Guidelines for post-cardiac arrest care recommend blood pressure optimization as one component of neuroprotection. Although some retrospective clinical studies suggest that postresuscitation hypotension may be harmful, and laboratory studies suggest that a postresuscitation hypertensive surge may be protective, empirical data are few. In this study, we prospectively measured blood pressure over time during the postresuscitation period and tested its association with neurologic outcome. ⋯ We found that time-weighted average mean arterial pressure was associated with good neurologic outcome at a threshold of mean arterial pressure greater than 70 mm Hg.

We present the case of a 20-year-old woman with a history of hypoplastic left heart syndrome, D-transposition of the great arteries, and mitral/pulmonary valve atresia without surgical palliation, who was admitted with persistent atrial flutter/fibrillation and worsening cardiac function from amiodarone-induced thyrotoxicosis. Despite maximal medical therapy, she continued to have uncontrolled thyrotoxicosis and underwent successful emergent thyroidectomy under general anesthesia. With advances in the treatment of congenital heart disease, more patients are surviving to adulthood and require emergent noncardiac surgery. Therefore, anesthesiologists must understand the principles for managing patients with congenital heart disease and how the patient's physiology may affect the anesthetic plan.
