Multicenter Study Clinical Trial
Topical lidocaine patch 5% may target a novel underlying pain mechanism in osteoarthritis.
Recent literature and animal research has provided insight to potentially new analgesic targets for managing osteoarthritis (OA) pain. Primary afferent neurons located in affected joints express excessive amounts of abnormally functioning sodium (Na) channels on their surface in response to the inflammatory process. These Na channels may play an integral role in production of pain and hyperalgesia. ⋯ The lidocaine patch 5% was generally well tolerated and no patients discontinued due to treatment-related adverse events. Given the open-label design, lack of a control group, and small sample size, the findings from our pilot study need to be confirmed by larger randomized controlled trials. Topical lidocaine patch 5% may provide clinicians with a novel, non-systemic therapy for OA pain with a unique mechanism of action.

Multicenter Study[Assessment of intubation procedures at reference pediatric and neonatal intensive care units].
To describe intubation procedures in two pediatric and two neonatal intensive care units in the city of Porto Alegre. ⋯ There was no established routine for intubation procedures in the units studied, and the use of muscle relaxants was not usual. The absence of adequate muscle relaxation is associated with more intubation attempts, difficulties and hypoxemia during the intubation procedure.

Multicenter Study Clinical TrialRopivacaine in neonates and infants: a population pharmacokinetic evaluation following single caudal block.
The aims of this study were to evaluate pharmacokinetics, efficacy and safety of ropivacaine in infants aged 0-12 months following a single caudal injection. ⋯ Following a caudal block with ropivacaine 2 mg x kg(-1) plasma concentrations of unbound ropivacaine were well below threshold levels for toxicity in adults. Apparent volume of distribution is unchanged, apparent unbound clearance increases and the terminal half-life decreases with age in 0-12-month-old neonates and infants. The postoperative pain management provided adequate analgesia and was well tolerated.
