OBJECTIVES: To assess the impact of approach on surgical outcomes in otherwise healthy obese patients undergoing partial nephrectomy for small renal masses. PATIENTS AND METHODS: Using our institutional partial nephrectomy database, we abstracted data on otherwise healthy (Charlson score ≤1 and bilateral kidneys), obese patients (body mass index >30 kg/m(2) ) with small renal masses (<4 cm) treated between 2011 and 2015. The primary outcomes were intraoperative transfusion, operative time, length of stay, and postoperative complications...

Open surgical repair of an aortic aneurysm requires aortic cross-clamping, resulting in temporary ischemia of all organs and tissues supplied by the aorta distal to the clamp. Major complications of open aneurysm repair due to aortic cross-clamping include renal ischemia-reperfusion injury and postoperative colonic ischemia in case of supra- and infrarenal aortic aneurysm repair. Ischemia-reperfusion injury results in excessive production of reactive oxygen species and in oxidative stress, which can lead to multiple organ failure...

CONTEXT: Pre-existing renal dysfunction presents specific features that anesthesiologists must deal with. Anesthesia and renal function are connected and can interfere with each other. Induced hypotension anesthesia and the toxic effects of anesthetic drugs can further deteriorate renal function. EVIDENCE ACQUISITION: Decreased renal function can prolong anesthetic drug effects by decreased elimination of these drugs. Anesthesia can deteriorate renal function and decreased renal function can interfere with drug elimination leading to their prolonged effect...

Inhalation anesthetics provide myocardial protection for cardiac surgery. This study was undertaken to compare the perioperative effects between isoflurane and fentanyl-midazolam-based anesthesia for heart transplantation. A retrospective cohort study was conducted by reviewing the medical records of heart transplantation in a single medical center from 1990 to 2013. Patients receiving isoflurane or fentanyl-midazolam-based anesthesia were included. Those with preoperative severe pulmonary, hepatic, or renal comorbidities were excluded...

OBJECTIVE: To investigate the protective effects of high-dose ulinastatin on the vital organs in patients undergoing total arch replacement for type A aortic dissection. METHODS: Between September 2014 and March 2016, 66 patients with type A aortic dissection underwent total arch replacement at our center. Thirty-six of the patients received ulinastatin treatment at 300 000 U/8 h from admission to 3 days postoperatively and at 300 000 U/2 h during cardiopulmonary bypass surgery (UTI group), and the other 30 patients did not receive perioperative ulinastatin treatment (control group)...

INTRODUCTION: The minimally invasive treatment of small renal masses with cryoablation has become increasingly widespread during the past 15 years. Studies with long-term follow-up are beginning to emerge, showing good oncological control, however, tumors with a central and endophytic location seem to possess an increased risk of treatment failure. Such tumors are likely to be subjected to a high volume of blood giving thermal protection to the cancerous cells. Arterial clamping during freezing might reduce this effect but at the same time subject the kidney to ischemia...

BACKGROUND: Cardiac surgery-related acute kidney injury (AKI) is a common postoperative complication that greatly increases morbidity and mortality. There are currently no effective interventions to prevent AKI associated with cardiac surgery. Experimental data have shown that administration of the mineralocorticoid receptor blocker spironolactone prevents renal injury induced by ischemia-reperfusion in rats. The objective of this study was to test whether short-term perioperative administration of oral spironolactone could reduce the incidence of AKI in cardiac surgical patients...

OBJECTIVE: Late stroke and death rates are anticipated to be higher in patients undergoing carotid endarterectomy (CEA) compared to healthy counterparts. However, little is known regarding predictors, other than the baseline comorbidities. We have recently shown that dual intraoperative Somatosensory Evoked Potentials (SSEP) and electroencephalogram (EEG) monitoring improves the ability to predict perioperative strokes. We seek to determine if dual intraoperative monitoring (IOM) can further predict long-term strokes and death...

BACKGROUND: Cardiovascular disease is the leading cause of morbidity and mortality in patients with chronic kidney disease (CKD). In fact, death from cardiovascular disease is the number one cause of graft loss in kidney transplant (KTx) patients. Compared to patients on dialysis, CKD patients with KTx have increased quality and length of life. It is not known, however, whether outcomes of coronary artery bypass graft (CABG) surgery differ between CKD patients with KTx or on dialysis...

Recipient diabetes accounts for ~34% of end stage renal disease in patients awaiting renal transplantation and has been linked to poor graft function. We conducted a single center, open label, randomized controlled trial to determine if moderately intense glucose control during allograft reperfusion would reduce the incidence of poor graft function. Adult diabetics undergoing deceased donor renal transplant were randomized to moderately intense glucose control (n=30) or standard control (n=30). The primary outcome was poor graft function (dialysis within seven days of transplant or failure of serum creatinine to fall by 10% for three consecutive days)...

OBJECTIVES: Contemporary guidelines for treatment of localized renal masses suggest nephron-sparing surgery (NSS) as an option for T1a tumors in appropriate patients. Large comparative series assessing the risk of complications between open and robotic approaches for partial nephrectomy are lacking. Our objective is to assess differences in complications following robotic (RPN) and open partial nephrectomy (OPN) among experienced surgeons. PATIENTS AND METHODS: We identified patients in our IRB-approved, prospectively maintained database who underwent OPN or RPN for management of unifocal, T1a renal tumors at our institution between January 2011 and August 2015...

OBJECTIVES: Aortic arch surgery is associated with substantial perioperative risks. New prostheses as well as novel perfusion techniques have been developed to reduce the risks of these procedures. The routine application of these new techniques warrants reassessment of risk factors of aortic arch repair. METHODS: Between April 2010 and December 2015, 199 patients [61% male, median age 63 years (interquartile range 52-70 years)] underwent total aortic arch repair in our institution...

BACKGROUND: Blood transfusions are associated with morbidity and mortality. However, restrictive thresholds could harm patients less able to tolerate anemia. Using a context-specific approach (according to patient characteristics and clinical settings), the authors conducted a systematic review to quantify the effects of transfusion strategies. METHODS: The authors searched MEDLINE, EMBASE, CENTRAL, and grey literature sources to November 2015 for randomized controlled trials comparing restrictive versus liberal transfusion strategies applied more than 24 h in adult surgical or critically ill patients...

The role of prostaglandin E1 (PGE1) infusion in improving early graft function has not been well defined, especially in the scenario of living donor liver transplantation (LDLT). We designed a randomized, double-blind, placebo-controlled trial to evaluate the role of perioperative PGE1 infusion in LDLT. Patients in the study arm received PGE1 (alprostadil) at the rate of 0.25 μg/kg/hour, starting at 1 hour after portal venous reperfusion, and continued for 96 hours. The primary endpoint was early allograft dysfunction (EAD)...

PURPOSE: To evaluate if the preoperative administration of levosimendan in patients with right ventricular (RV) dysfunction, pulmonary hypertension, and high perioperative risk would improve cardiac function and would also have a protective effect on renal and neurological functions, assessed using two biomarkers neutrophil gelatinase-associated lipocalin (N-GAL) and neuronal enolase. METHODS: This is an observational study. Twenty-seven high-risk cardiac patients with RV dysfunction and pulmonary hypertension, scheduled for cardiac valve surgery, were prospectively followed after preoperative administration of levosimendan...

The incidence of acute kidney injury (AKI) is a frequent and serious complication of cardiac surgery. In 2013, 95% of cardiac surgical procedures performed in Australia and New Zealand used cardiopulmonary bypass (CPB). AKI following CPB is well known, yet the perioperative factors contributing to its development are incompletely understood. AKI following CPB has significant implications on both short-term and long-term outcomes. The techniques for conducting CPB have evolved, moving towards evidence-based practice; however, there is still no generally accepted definition of optimal perfusion and its conduct...
