Physiological changes associated with ageing could negatively impact the crisis resource management skills of acute care physicians. This study was designed to determine whether physician age impacts crisis resource management skills, and crisis resource management skills learning and retention using full-body manikin simulation training in acute care physicians. ⋯ A reduced amount of prior simulation training and increased years in practice, but not age on its own, were significant predictors of low baseline crisis resource management performance. Simulation-based education leads to crisis resource management learning that is well retained for 3-6 months, regardless of age or years in practice.

Observational Study
Association of clonal haematopoiesis with severe postoperative complications in patients undergoing radical oesophagectomy.
Clonal haematopoiesis (CH) is an age-associated clonal expansion of blood cells driven by leukaemia-associated somatic mutations. Although CH has been reported to be a risk factor for leukaemia and a number of non-haematopoietic diseases, its role in perioperative medicine remains unexplored. ⋯ ChiCTR2100044175 (Chinese Clinical Trial Registry, http://www.chictr.org.cn/showproj.aspx?proj=123193).

Randomized Controlled Trial
Opioid-free anaesthesia reduces postoperative nausea and vomiting after thoracoscopic lung resection: a randomised controlled trial.
Intraoperative opioid use has a positive relationship with postoperative nausea and vomiting (PONV), and opioid-free anaesthesia (OFA) might reduce PONV. We investigated whether OFA compared with opioid-based anaesthesia would reduce PONV during the first 2 postoperative days among patients undergoing thoracoscopic lung resection. ⋯ Chinese Clinical Trial Registry (ChiCTR2200059710).

Tranexamic acid is an antifibrinolytic drug that is commonly administered for obstetric haemorrhage. Conventional viscoelastic tests are not sensitive to tranexamic acid, but the novel ClotPro® TPA-test can measure tranexamic acid-induced inhibition of fibrinolysis. We aimed to evaluate the TPA-test in pregnant and non-pregnant women. ⋯ The ClotPro® TPA-test is sensitive in detecting inhibition of fibrinolysis by tranexamic acid in whole blood samples of pregnant and non-pregnant women. The concentration-effect relationship of tranexamic acid to inhibit fibrinolysis in whole blood did not differ for women in the first, second, and third trimester or for non-pregnant women.

Comparative Study
Comparative analysis of andexanet alfa and prothrombin complex concentrate in reversing anticoagulation by rivaroxaban ex vivo.
The comparative effectiveness of the specific antidote andexanet alfa vs the nonspecific therapy four-factor prothrombin complex concentrates (4F-PCCs) as reversal agents for direct factor Xa (FXa) inhibitors in severely bleeding patients is unclear. We hypothesised that specific reversal using andexanet alfa would be more effective than a high dose of PCC (50 IU kg-1) for reversing the FXa inhibitor rivaroxaban. ⋯ In contrast to thrombin generation measurements, haemostatic reversal of rivaroxaban using high-dose 4F-PCCs exhibited similar efficacy as andexanet alfa in flow chamber experiments. The haemostatic effects of 4F-PCCs and andexanet alfa in the context of bleeding patients taking FXa inhibitors requires further study.
