Randomized Controlled Trial Comparative Study Clinical Trial
Ropivacaine plasma concentrations are similar during continuous lumbar plexus blockade using the anterior three-in-one and the posterior psoas compartment techniques.
To compare ropivacaine blood concentrations obtained after a continuous lumbar plexus block performed either by the anterior three-in-one femoral (FEM) technique or the posterior (psoas compartment; PSOAS) technique. ⋯ Although the posterior PSOAS block results in higher early plasma concentrations of local anesthetic than the anterior three-in-one FEM block, both techniques are equivalent with regards to their potential toxicity when a continuous infusion is administered. Local anesthetic accumulation occurs with an infusion of ropivacaine 0.2% at 12 mL.hr(-1) and can lead to potentially dangerous concentrations at 48 hr.

Randomized Controlled Trial Clinical Trial
Tranexamic acid reduces the need for allogenic red blood cell transfusions in patients undergoing total hip replacement.
This prospective randomized double-blind trial evaluates the efficacy of tranexamic acid (TA) to decrease blood losses and red blood cell transfusions in patients undergoing primary unilateral total hip replacement (THR). ⋯ TA did not change measured blood losses but reduced red blood cell transfusion requirements in patients undergoing primary unilateral THR.

To present a case of laryngeal damage in an infant caused by a too large and inappropriately designed cuffed tracheal tube. ⋯ The larger than expected tracheal tube with its intra-laryngeal cuff position in a 13-month-old child likely caused mucosal damage and an inflammatory reaction within the larynx resulting in granulation tissue formation and fibrous healing around the tracheal tube.
