Accurate risk reassessment after surgery is crucial for postoperative planning for monitoring and disposition. Existing postoperative mortality risk prediction models using preoperative features do not incorporate intraoperative hemodynamic derangements that may alter risk stratification. Intraoperative vital signs may provide an objective and readily available prognostic resource. Our primary objective was to derive and internally validate a logistic regression (LR) model by adding intraoperative features to established preoperative predictors to predict 30-day postoperative mortality. ⋯ gov (NCT04014010); registered on 10 July 2019.

Tranexamic acid administration into the epidural space has not been previously reported. We describe our experience managing and investigating a drug error involving incorrect route of tranexamic acid administration through an epidural catheter. ⋯ Saline lavage of the epidural space may be considered if tranexamic acid has been administered into the epidural space. Early multidisciplinary team involvement combined with repeated postevent neurologic monitoring is recommended to guide therapy. Adoption of neuraxial route-specific connectors, when available, may be warranted to reduce Luer-type misconnections.

Randomized Controlled Trial
Titrated versus conventional anticoagulation management for thrombin generation in cardiac surgery: a randomized controlled trial.
Optimal heparin titration during cardiopulmonary bypass (CPB) may reduce coagulation system activation and preserve hemostatic function post-CPB. Our objective was to assess if the Heparin Management System (HMS) Plus improves heparin titration, thereby leading to higher thrombin generation post-CPB compared with activated clotting time (ACT)-guided management. ⋯ gov (NCT03347201); first submitted 12 October 2017.

Peripheral nerve blocks improve analgesia following hip fracture; however, there are little published data on safety and outcomes of continuous regional anesthetic techniques. Our institution offers pre- and perioperative, anesthesiologist-delivered ultrasound-guided suprainguinal fascia iliaca catheters (FICs) to patients with hip fracture. We aimed to document the safety profile of this technique and establish whether there are any significant clinical benefits in outcomes measured by the UK National Hip Fracture Database. ⋯ Our single-centre propensity-matched historical cohort study suggests that ultrasound-guided suprainguinal fascia iliaca catheterization is a safe technique for patients with hip fracture and that our service is deliverable and sustainable within the UK's National Health Service. This study did not show statistically significant differences in outcomes between patients treated with FIC and standard care. An adequately powered multicentre randomized controlled trial comparing these approaches is warranted.
