Pre-induction and post-discharge venous thromboembolism chemoprophylaxis should be considered in patients after major vascular open abdominal procedures.

Background: Venous thromboembolism (VTE) is a significant morbidity following major open abdominal surgery. While there are clear recommendations for perioperative and post-discharge VTE chemoprophylaxis in general surgery, guidance for vascular patients is unclear. We compared the incidence of VTE in vascular versus general surgery cases and then investigated the timing of VTE in vascular patients.

Heparin concentration c in a blood extracorporeal circulation has been real-timely predicted based on the relaxation strength Δε at relaxation frequency f extracted by relaxation time distribution (RTD). The simulated extracorporeal circulation was conducted to optimize the number of Δε for the prediction of c using the porcine whole blood (WB) and low-leukocyte and -platelet blood (LLPB) under the condition of the gradual increment of c from 0 to 8 U/mL with constant flow rate and blood temperature. The experimental results show that among the three relaxation strengths Δε, Δε and Δε (in ascending order of frequency), Δε at f = 5.

Deep venous thrombosis (DVT) represents a significant postoperative complication after artificial femoral head replacement, with the incidence increasing proportionally with patient age. This study aimed to evaluate the effect of early postoperative use of intermittent pneumatic compression devices (IPC), followed by the combined use of low molecular weight heparin (LMWH) after 48 hours, for the prevention of postoperative lower limb DVT in elderly patients undergoing hip arthroplasty. The retrospective study included 100 elderly patients who underwent unilateral femoral head replacement.

Introduction: The Society for Pediatric Anesthesia Quality and Safety Committee developed the Pediatric Regional Anesthesia Time-Out Checklist, consisting of 14 safety items intended to be reviewed by an anesthesia team prior to a regional anesthetic. Primarily, we hypothesized that use of this Checklist would increase the number of safety items performed compared with no checklist, evaluating the usefulness of this tool. Secondarily, we hypothesized that, after checklist training, subjects would show better clinical judgment by electing to perform a regional anesthetic in scenarios in which no programmed error existed and electing to not perform a regional anesthetic in scenarios in which a programmed error did exist.

Our work describes the green synthesis of silver sulfide nanoparticles (AgS NPs) and their formulation into polycaprolactone fibers (PCL), aiming to improve the multifunctional biological performance of PCL membranes as scaffolds. For this purpose, an extract of rosemary () was employed as a reducing agent for the AgS NPs, obtaining irregular NPs and clusters of 5-60 nm, with a characteristic SPR absorption at 369 nm. AgS was successfully incorporated into PCL fibers by electrospinning using heparin (HEP) as a stabilizer/biocompatibility agent, obtaining nanostructured fibers with a ca.
