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.

Randomized Controlled Trial
Dexmedetomidine administration during brain tumour resection and postoperative delirium: a randomised controlled trial.
Delirium is common, especially after neurosurgery. Dexmedetomidine might reduce delirium by improving postoperative analgesia and sleep quality. We tested the primary hypothesis that dexmedetomidine administration during intracerebral tumour resection reduces the incidence of postoperative delirium. ⋯ NCT04674241.

Randomized Controlled Trial
Thromboelastometry-guided treatment algorithm in postpartum haemorrhage: a randomised, controlled pilot trial.
Postpartum haemorrhage causes significant mortality among parturients. Early transfusion of blood products based on clinical judgement and conventional coagulation testing has been adapted to the treatment of postpartum haemorrhage, but rotational thromboelastometry (ROTEM) may provide clinicians means for a goal-directed therapy to control coagulation. We conducted a parallel design, randomised, controlled trial comparing these two approaches. We hypothesised that a ROTEM-guided protocol would decrease the need for red blood cell transfusion. ⋯ NCT02461251.
