Randomized Controlled TrialCentral Venous-to-Arterial CO2 Difference-Assisted Goal-Directed Hemodynamic Management During Major Surgery-A Randomized Controlled Trial.
Different goals have guided goal-directed therapy (GDT). Protocols aiming for central venous-to-arterial carbon dioxide gap (DCO2) <6 mm Hg have improved organ function in septic shock. Evidence for use of DCO2 in the perioperative period is scarce. We aimed to determine if a GDT protocol using central venous saturation of oxygen (SCvo2) and DCO2 reduced organ dysfunction and intensive care unit (ICU) stay in American Society of Anesthesiologist (ASA) I and II patients undergoing major surgeries compared to pragmatic goal-directed care. ⋯ GDT guided by DCO2 did not improve organ function in our cohort. It resulted in greater use of dobutamine, improved tissue oxygen parameters, and decreased length of ICU stay. More evidence is needed for the routine use of DCO2 in sicker patients. In the absence of cardiac output monitors, it may be a readily available, less-expensive, and underutilized parameter for major surgical procedures.

Observational StudyAssociation Between Preoperative Fibrinogen-to-Albumin Ratio and All-Cause Mortality After Off-Pump Coronary Artery Bypass Grafting: A Retrospective Observational Study.
The fibrinogen-to-albumin ratio (FAR) is a recently introduced prognostic marker for patients with coronary artery disease. The present study investigated whether the FAR is associated with clinical outcome after off-pump coronary artery bypass grafting (OPCAB). ⋯ A higher FAR is associated with increased all-cause mortality after OPCAB. The preoperative FAR could be a prognostic factor for predicting higher mortality after OPCAB.

ReviewPerioperative management in complex spine surgery: a narrative review.
The last two decades have seen a significant increase in the number of spine surgical procedures performed worldwide. This type of surgery includes a wide variety of procedures, from mini-invasive discectomies to multilevel spinal arthrodesis and osteotomies. ⋯ We will discuss preoperative concerns, intraoperative management including airway management, choice of maintenance, intraoperative neuromonitoring and anesthetic effect, blood management and the dynamic topic of anesthetic and analgesic techniques. Finally, we will briefly address the issue of perioperative complications as they relate specifically to spine surgery.

Association Between Frailty and Clinical Outcomes and Quality of Life in Older Adults Following Hip Fracture Surgery: A Retrospective Cohort Study.
Hip fracture is a serious event in the older population and is associated with morbidity, mortality, and disability among those who survive. Emerging evidence suggests that frailty is pertinent to the clinical outcomes of older patients with hip fracture. ⋯ Frailty status is associated with adverse postoperative outcomes, mortality, and low quality of life 12 months after hip fracture surgery in older patients.

Randomized Controlled TrialControl of Postoperative Hypotension Using a Closed-Loop System for Norepinephrine Infusion in Patients After Cardiac Surgery: A Randomized Trial.
Vasopressors are a cornerstone for the management of vasodilatory hypotension. Vasopressor infusions are currently adjusted manually to achieve a predefined arterial pressure target. We have developed a closed-loop vasopressor (CLV) controller to help correct hypotension more efficiently during the perioperative period. We tested the hypothesis that patients managed using such a system postcardiac surgery would present less hypotension compared to patients receiving standard management. ⋯ Closed-loop control of norepinephrine infusion significantly decreases postoperative hypotension compared to manual control in patients admitted to the ICU after cardiac surgery.
