Randomized Controlled Trial
A randomised non-inferiority trial comparing the effectiveness of oral versus intravenous tranexamic acid in primary total hip and knee arthroplasty.
Tranexamic acid (TXA) reduces rates of blood transfusion for total hip arthroplasty (THA) and total knee arthroplasty (TKA). Although the use of oral TXA rather than intravenous (i.v.) TXA might improve safety and reduce cost, it is not clear whether oral administration is as effective. ⋯ Oral TXA can be administered in the preoperative setting before THA or TKA and performs similarly to i.v. TXA with respect to blood loss and transfusion rates. Switching from i.v. to oral TXA in this setting has the potential to improve patient safety and decrease costs.

Determination of reference ranges for the ClotPro® thromboelastometry device in paediatric patients.
A new thromboelastometry analyser (ClotPro®) was developed with advanced diagnostics. The reference ranges of ClotPro® in children ages 0-16 yr have not been reported. ⋯ NCT04190615.

The dysfunction of the blood-brain barrier could contribute to the pathogenesis of the perioperative neurocognitive disorder. In a recent study published in the British Journal of Anaesthesia, Yang and colleagues developed an innovative microfluidics-assisted blood-brain barrier device to investigate the effects of neuroimmune interactions on blood-brain barrier opening. The findings are important and timely to understanding the mechanistic insights of perioperative neurocognitive disorder.

Ultrasound-guided regional anaesthesia relies on the visualisation of key landmark, target, and safety structures on ultrasound. However, this can be challenging, particularly for inexperienced practitioners. Artificial intelligence (AI) is increasingly being applied to medical image interpretation, including ultrasound. In this exploratory study, we evaluated ultrasound scanning performance by non-experts in ultrasound-guided regional anaesthesia, with and without the use of an assistive AI device. ⋯ NCT05156099.

Sugammadex reversal of neuromuscular block facilitates recovery of neuromuscular function after surgery, but the drug is expensive. We evaluated the effects of sugammadex on hospital costs of care. ⋯ The effects of using sugammadex on costs of care depend on patient risk, defined based on comorbidities and admission status. We observed lower costs of care in patients with lower risk and higher costs of care in hospitalised surgical patients with severe comorbidities.
