ReviewReducing perioperative cardiac morbidity and mortality: is this the right goal?
One million people die annually following noncardiac surgery and 4% of patients suffer an adverse cardiac event after surgery. As the number of people having surgery grows, our ability to risk stratify patients becomes more important, particularly in the setting of perioperative myocardial ischemia/necrosis. ⋯ The presence of troponin elevations following noncardiac surgery, particularly in at-risk patients, may enable practitioners to better identify high-risk patients in the postoperative setting. After recognizing those patients at increased risk for poor outcomes, practitioners can then make interventions, which may decrease the patients' in-hospital, 30-day and potentially long-term mortality.

The review is focused on the challenge of managing airway and ventilation in the intraoperative and postoperative period. ⋯ The combination of planning extubation of predicted and unpredicted difficult airway, both intraoperative low tidal volume and low FiO2 with LRM and PEEP at different points of surgery and postoperative noninvasive ventilation should be considered in patients undergoing surgery to decrease the rate of postoperative pulmonary complications and major fatal complications such as brain damage and death.

Fluid resuscitation is a common intervention in acute medical practice. The optimum fluid for resuscitation remains hotly debated and it is likely to vary from one clinical situation to another. Human albumin solutions have been available since the 1940s, but their use varies greatly around the world. This review examines the current evidence for and against the use of albumin as a resuscitation fluid. ⋯ Fluid resuscitation with albumin is well tolerated and produces similar results to resuscitation with saline. Albumin should be avoided in patients with traumatic brain injury; possible benefits in adults with severe sepsis remain to be confirmed.

Using perioperative goal-directed therapy (GDT) or peroperative hemodynamic optimization significantly reduces postoperative complications and risk of death in patients undergoing noncardiac major surgeries. In this review, we discuss the main changes in the field of perioperative optimization over the last few years. ⋯ GDT is safe and more likely to tailor the amount of fluids given to the amount of fluids actually needed. This approach includes assessment of fluid responsiveness and, if necessary, the use of inotropes; moreover, this approach can be coupled with a restrictive strategy for maintenance fluids. These strategies have been increasingly incorporated into protocols for perioperative hemodynamic optimization in high-risk patients undergoing major surgery, resulting in more appropriate use of fluids, vasopressors, and inotropes.
