ReviewPerioperative Use of Coagulation Factor Concentrates in Patients Undergoing Cardiac Surgery.
Coagulopathy and bleeding are common in patients undergoing cardiac surgery, with a perioperative transfusion rate in excess of 50%. The mechanism of coagulopathy associated with cardiac surgery using cardiopulmonary bypass is multifactorial. Historically, coagulation factor-mediated bleeding in such instances has been treated with allogeneic plasma transfusion. ⋯ Formulations of factor concentrates include single and multifactor concentrates and both human and recombinant-derived products. Off-label use of factor concentrates for coagulopathy and bleeding associated with cardiac surgery has been described for decades; however, sound clinical research with regard to this practice is limited. This review highlights the literature discussing the use of factor concentrates in patients undergoing cardiac surgery and provides an overview of reasonable uses or lack thereof for factor concentrates in clinical practice.

Randomized Controlled Trial Comparative StudyUltrasound Guided Out-of-Plane Versus In-Plane Transpectoral Left Axillary Vein Cannulation.
The primary objective was to compare the frequency of first-attempt successful axillary vein cannulation by the Seldinger technique using out-of-plane ultrasound guidance versus in-plane imaging. Between the two ultrasound imaging planes, this study also compared the number of attempts that were necessary for the cannulation of the left axillary vein along with the number of needle redirections that had to be done for final cannulation of the vein. Incidence of complications and the number of times the procedure was abandoned also were compared between the two imaging planes. ⋯ Out-of-plane ultrasound imaging during axillary vein cannulation increased the chance of first-attempt successful cannulation. Axillary vein cannulation under out-of-plane ultrasound imaging also appeared to be quicker and was preferable in terms of the fewer number of attempts that were necessary for a successful vein cannulation.

Review Meta Analysis Comparative StudyMitral Regurgitation Grading in the Operating Room: A Systematic Review and Meta-analysis Comparing Preoperative and Intraoperative Assessments During Cardiac Surgery.
To assess differences in mitral regurgitation (MR) grade between the preoperative and the intraoperative evaluations. ⋯ Intraoperative assessment under "GA-only" significantly underestimated MR. A more accurate intraoperative evaluation can be obtained with afterload manipulation, although HM strategy carries high risk of clinically significant overestimation.

Randomized Controlled Trial Comparative StudyComparison Between Pressure-Regulated Volume-Controlled and Volume-Controlled Ventilation on Oxygenation Parameters, Airway Pressures, and Immune Modulation During Thoracic Surgery.
To compare 2 different ventilatory strategies: pressure-regulated volume-controlled (PRVC) versus volume-controlled ventilation during thoracotomy. ⋯ The PRVC mode during 1-lung ventilation in thoracic surgery caused a favorable effect on oxygenation parameters, respiratory mechanics, and immune modulation during thoracic surgery.
