A clinical trial of volume- versus pressure-controlled intraoperative ventilation during laparoscopic bariatric surgeries.

Background: Intra-operative ventilation is often challenging in patients with morbid obesity undergoing bariatric surgery.

Objectives: To test the noninferiority of pressure-controlled ventilation (PCV) to volume-controlled ventilation (VCV) in respiratory mechanics.

Setting: Bariatric Surgery Center, Iran.

The utilization spectrum of cardiac output monitoring devices among anesthesiology programs across Veterans Health Administration in the United States.

Background: Electronic monitoring of physiologic variables has gained widespread support over the past decade for critical patients in the intensive care setting. Specifically, anesthesiologists have increased the emphasis and practice of hemodynamic control through monitoring cardiac output (CO). However, these physicians are presented with several options in terms of how they wish to study the trend of this physiologic parameter.

Acute kidney injury after non-cardiovascular surgery: risk factors and impact on development of chronic kidney disease and long-term mortality.

Objective: To identify factors associated with acute kidney injury (AKI) and its progression to chronic kidney disease (CKD) in a non-cardiac/non-vascular surgery setting.

Methods: This study examined the Veterans Affairs Surgical Quality database for surgical entries between 2000-2014. Demographics, comorbidities, laboratory findings and hospital outcomes were assessed.
