Randomized Controlled Trial
Influence of epidural mixture and surgery on bladder function after open renal surgery: a randomized clinical trial.
In a previous observational study, thoracic epidural analgesia (TEA) after open renal surgery resulted in clinically relevant postvoid residuals (PVRs). This study aimed to investigate the individual contribution of epidurally administrated drugs and surgery in bladder dysfunction. ⋯ Thoracic epidurally administrated bupivacaine resulted in clinically relevant PVRs based on impaired detrusor function. The addition of fentanyl enhanced this effect without generating greater PVRs. After surgery, the voiding phase was not further impaired; however, bladder compliance was decreased.

Randomized Controlled Trial
Effects of fibrinogen concentrate as first-line therapy during major aortic replacement surgery: a randomized, placebo-controlled trial.
Fibrinogen is suggested to play an important role in managing major bleeding. However, clinical evidence regarding the effect of fibrinogen concentrate (derived from human plasma) on transfusion is limited. The authors assessed whether fibrinogen concentrate can reduce blood transfusion when given as intraoperative, targeted, first-line hemostatic therapy in bleeding patients undergoing aortic replacement surgery. ⋯ Hemostatic therapy with fibrinogen concentrate in patients undergoing aortic surgery significantly reduced the transfusion of allogeneic blood products. Larger multicenter studies are necessary to confirm the role of fibrinogen concentrate in the management of perioperative bleeding in patients with life-threatening coagulopathy.
