Randomized Controlled Trial Comparative Study
The catheter-over-needle assembly facilitates delivery of a second local anesthetic bolus to prolong supraclavicular brachial plexus block without time-consuming catheterization steps: a randomized controlled study.
Single-shot delivery of a supraclavicular brachial plexus block is effective for providing outpatient surgical anesthesia; however, patients generally must use oral analgesics to control pain shortly after discharge from the hospital. Catheterized delivery of supraclavicular blocks can be challenging to perform. We aimed to show that administering a second postoperative bolus of local anesthetic through a catheter placed by a catheter-over-needle assembly not only avoids time-consuming steps but also provides an extended analgesic effect compared with the traditional single-shot approach. ⋯ Using the catheter-over-needle assembly for supraclavicular brachial plexus block facilitated effective delivery of a supplementary bolus of local anesthetic without extending the time to perform the block or increasing the number of steps. It also prolonged analgesia significantly compared with the single-shot approach. This trial was registered at: ClinicalTrials.gov, ID: NCT01522066.

Randomized Controlled Trial Comparative Study
Factors that influence the selection of sterile glove brand: a randomized controlled trial evaluating the performance and cost of gloves.
To determine whether glove use modifies tactile and psychomotor performance of health care providers when compared with no glove use and to evaluate factors that influence the selection of sterile glove brand. ⋯ Given the observed similarities in touch sensitivity and psychomotor performance associated with five different glove types, our results suggest that subjective provider preferences, such as glove comfort, should be balanced against material costs.
