ReviewAnesthesia for nonintubated video-assisted thoracic surgery.
This review focuses primarily on nonintubated video-assisted thoracic surgery (NIVATS), and discusses advantages, indications, anesthetic techniques, and approaches to intraoperative crisis management. ⋯ Although anesthesia for NIVATS is associated with some of the same risks as general anesthesia with endotracheal intubation, NIVATS can be successfully performed in carefully selected patients.

ReviewDoes fluid management affect the occurrence of acute kidney injury?
To describe the potential impact of different fluid management strategies on renal outcomes in critically ill and postoperative patients. ⋯ Although synthetic colloids should be avoided in patients with or at risk of AKI, the renal efficacy of using albumin solutions and/or balanced crystalloids as alternatives to 0.9% sodium chloride in high-risk patients is yet to be confirmed or refuted. Improved goal-directed protocols, which minimize unnecessary fluid administration and reduce potentially harmful effects of fluid overload, need to be developed and tested.

The incidence of cardiac surgery-associated acute kidney injury (CS-AKI) continues to increase and is associated with significant morbidity and mortality. Early diagnosis and identification of patients at risk are extremely important. Therefore, identifying associated risk factors, biomarkers for earlier detection, prevention and therapeutic options for CS-AKI warrant special attention. ⋯ It is extremely important to identify those who are at increased risk for CS-AKI with the foremost goal being that of prevention to help decrease morbidity and mortality. Combining functional and tubular biomarkers can assist with early identification. Once identified, early interventions including avoidance of nephrotoxins, decreasing cardiopulmonary bypass time, avoiding fluid overload and early initiation of renal replacement therapy may lead to improved clinical outcomes.

ReviewMortality and cost of acute and chronic kidney disease after cardiac surgery.
Acute and chronic kidney diseases (AKI and CKD) have far-reaching implications for surgical patients in regards to postoperative outcomes and hospital cost. We review the recent literature on the effects of AKI and CKD on morbidity, mortality, and resource utilization among cardiac surgery patients. ⋯ AKI and CKD remain prevalent, morbid, and costly conditions for cardiac surgery patients. Better risk stratification, early diagnosis, and earlier interventions are needed to prevent the consequences of these diseases.

ReviewPreoperative evaluation and preparation of the morbidly obese patient.
This review aims to familiarize with the most current findings regarding preoperative evaluation and preparation of morbidly obese patients prior to elective, noncardiac surgery. In the light of the increasing number of surgical patients being morbidly obese, the knowledge of evidence-based preoperative evaluation strategies is profound for a rational approach. ⋯ Synthesis of proper medical history-taking and physical examination as well as detailed search for obstructive sleep apnea and metabolic syndrome are key components of preoperative evaluation. Further testing should be based on the findings of these steps and comprise the cardiac risk of the surgical procedure.
