Likely, maintained organ and notably cerebral perfusion, secures rapid recovery following anesthesia. To secure cerebral blood flow (CBF) at least mean arterial pressure (MAP) and the arterial carbon dioxide tension (PaCO2) need to be considered. CBF is "autoregulated", i.e. stays more or less stable within a MAP of 50-150 mmHg, but the lower limit appears to depend on the central blood volume and/or cardiac output, illustrated by a decrease in CBF at a MAP of 80 mmHg with a compromised central blood volume, while CBF remains constant with a MAP < 40 mmHg, if the central blood volume is maintained...

PURPOSE OF REVIEW: The purpose of this review is to identify chronic pulmonary conditions which may often not be recognized preoperatively especially before elective noncardiac surgery and which carry the highest risk of perioperative morbidity and mortality. RECENT FINDINGS: This review discusses some of the most recent studies that highlight the perioperative complications, and their prevention and management strategies. SUMMARY: Pulmonary hypertension is a well recognized risk factor for postoperative complications after cardiac surgery but the literature surrounding noncardiac surgery is sparse...

BACKGROUND: Patients with severely reduced left-ventricular ejection fraction carry a high risk of morbidity and mortality after cardiac surgery. Levosimendan can be used prophylactically in these patients having shown positive effects on short-term outcome. However, effects on long-term outcome and patient subgroups benefiting the most are unknown. We aim to address these topics with real-life data from our clinical practice. METHODS: Two hundred eigthy eight patients with preoperative LVEF ≤ 35% underwent cardiac surgery with cardiopulmonary bypass between 2009 and 2013...

STUDY OBJECTIVE: Children with congenital or acquired heart disease have an increased risk of anesthesia related morbidity and mortality. The child's anesthetic risk is related to the severity of their underlying cardiac disease, associated comorbidities, and surgical procedure. The goal of this project was to determine the ease of use of a preoperative risk stratification tool for assigning pediatric cardiac staff and to determine the relative frequency that children with low, moderate, and high risk cardiac disease present for non-cardiac surgery at a tertiary pediatric hospital...

Acute kidney injury (AKI) represents frequent complication after cardiac surgery using cardiopulmonary bypass (CPB). In the hope to enhance earlier more reliable characterization of AKI, we tested the utility of neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C (CysC) in addition to standard creatinine for early determination of AKI after cardiac surgery using CPB. Forty-one patients met the inclusion criteria. Arterial blood samples collected after induction of general anesthesia were used as baseline, further sampling occurred at CPB termination, 2 h after CPB, on the first and second day after surgery...

Therapeutic hypothermia was associated with increased mortality in patients with severe bacterial meningitis in a large randomized trial. It still remains a treatment strategy for comatose survivors of cardiac arrest. There are several potential advantages of inhalational anesthetics as long-term sedation agents compared to intravenous sedation, however, uncontrollable increases of intracranial pressure were observed in neurocritical patients. Here we present a patient with severe bacterial meningitis and secondary cardiac arrest where therapeutic hypothermia and inhalational anesthesia were successfully used...

BACKGROUND: Cardiac and renal injuries are common insults after cardiac surgeries that contribute to perioperative morbidity and mortality. Dexmedetomidine has been shown to protect several organs against ischemia/reperfusion-(I/R) induced injury. We performed a randomized controlled trial to assess the effect of dexmedetomidine on cardiac and renal I/R injury in patients undergoing cardiac surgeries. MATERIALS AND METHODS: Fifty patients scheduled for elective cardiac surgeries were randomized to dexmedetomidine group that received a continuous infusion of dexmedetomidine initiated 5 min before cardiopulmonary bypass (1 μg/kg over 15 min, followed by 0...

REVIEW
Sara E Neves
Patients with vascular disease and cardiac dysfunction present particular challenges to the anesthesiologist. They are hemodynamically brittle, at high risk of morbidity and mortality during surgery, and often carry additional comorbidities that increase their complexity and risk. Those with peripheral vascular disease should be assumed to have coronary artery disease and tend to have other systemic vascular problems. Poor cardiac function further worsens perfusion in an already compromised peripheral vascular system...

REVIEW
Julianne Ahdout, Michael Nurok
Anesthesia and surgery in patients with hepatic and cardiac dysfunction poses a challenge for anesthesiologists. It is imperative to optimize these patients perioperatively. Cirrhosis is associated with a wide range of cardiovascular abnormalities. Cirrhotic cardiomyopathy is characterized by blunted contractile responsiveness or systolic incompetence, and/or diastolic dysfunction. In liver disease, anesthetic drug distribution, metabolism, and elimination may be altered. Among patients with liver disease, propofol is a reasonable anesthetic choice and cisatracurium is the preferred neuromuscular blocker...

BACKGROUND: Coronary artery bypass graft (CABG) surgery with cardiopulmonary bypass (CPB) triggers an inflammatory reaction, leading to the development of myocardial damage and dysfunction. It is suggested that selenium (Se), an essential trace element, has a protective role against oxidative stress. Decreased intraoperative Se levels might be an independent predictive factor for postoperative multiorgan failure. In spite of its proposed advantages, however, the optimal timing and dosage are not well known...

BACKGROUND: The concept of brain-heart interaction has been described in several brain injuries. Traumatic brain injury (TBI) may also lead to cardiac dysfunction but evidences are mainly based upon experimental and clinical retrospective studies. METHODS: We conducted a prospective case-control study in a level I trauma center. Twenty consecutive adult patients with severe TBI were matched according to age and gender with 20 control patients. The control group included adult patients undergoing a general anesthesia for a peripheral trauma surgery...

BACKGROUND: Cerebral oxygen saturation (rSO2c) decrease from baseline greater than 20 % during infant cardiac surgery was associated with postoperative neurologic changes and neurodevelopmental impairment at 1 year of age. So far, there is no sufficient evidence to support the routine monitoring of rSO2c during general surgical procedures in children. We aimed to find out the frequency of cerebral desaturation 20 % or more from baseline and to identify possible predictors of change in cerebral oxygen saturation during neonatal and infant general surgery...

BACKGROUND: An increasing number of patients addicted to opium are experiencing awareness during coronary artery bypass surgery (CABG) as a result of tolerance to anesthetics. OBJECTIVES: This research was primarily intended to determine the potential diminishing effects of moderate hypothermia on anesthetic dosage and recall of anesthesia during the procedure. METHODS: In this double-blind randomized controlled trial, a total of 80 CABG candidates with known addiction to opium were divided into two groups: one normothermic (N) and the other moderately hypothermic (H), both undergoing induction as well as close monitoring from September 2014 to January 2016...
