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.

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.

Sugammadex Versus Neostigmine for Reversal of Residual Neuromuscular Blocks After Surgery: A Retrospective Cohort Analysis of Postoperative Side Effects.
Sugammadex and neostigmine given to reverse residual neuromuscular blockade can cause side effects including bradycardia, anaphylaxis, bronchospasm, and even cardiac arrest. We tested the hypothesis that sugammadex is noninferior to neostigmine on a composite of clinically meaningful side effects, or vice versa. ⋯ The composite incidence was less with neostigmine than with sugammadex, but only by 0.4% (a negligible clinical effect). Since 250 patients would need to be given neostigmine rather than sugammadex to avoid 1 episode of a minor complication such as bradycardia or bronchospasm, we conclude that sugammadex and neostigmine are comparably safe.

Regional Anesthesia Associated With Decreased Inpatient and Outpatient Opioid Demand in Tibial Plateau Fracture Surgery.
Regional anesthesia (RA) has been used to reduce pain and opioid usage in elective orthopedic surgery. The hypothesis of this study was that RA would be associated with decreased opioid demand in tibial plateau fracture surgery. ⋯ In tibial plateau fracture surgery, RA was associated with reduced inpatient opioid consumption up to 48 hours postoperatively and reduced outpatient opioid demand up to 90 days postoperatively without an associated risk of acute compartment syndrome. RA should be considered for patients undergoing tibial plateau fracture fixation.
