Randomized Controlled Trial
Use of ultrasound guidance improves central venous catheter insertion success rates among junior residents.
The purpose of this study was to determine whether junior residents had higher rates of first cannulation and overall success at central venous catheter insertions with the use of ultrasound (US) guidance compared to the landmark technique. ⋯ Dynamic and static US guidance during central venous catheter insertion was associated with improved in-hospital first cannulation rates and overall success rates of insertions by junior residents.

Randomized Controlled Trial Comparative Study
A trainee-based randomized comparison of stimulating interscalene perineural catheters with a new technique using ultrasound guidance alone.
Compared to the well-established stimulating catheter technique, the use of ultrasound guidance alone for interscalene perineural catheter insertion is a recent development and has not yet been examined in a randomized fashion. We hypothesized that an ultrasound-guided technique would require less time and produce equivalent results compared to electrical stimulation (ES) when trainees attempt interscalene perineural catheter placement. ⋯ Trainees using a new ultrasound-guided technique can place inter-scalene perineural catheters in less time compared to a well-documented technique using ES with a stimulating catheter and can produce equivalent results.

Randomized Controlled Trial Comparative Study
Ultrasound guidance versus electrical stimulation for femoral perineural catheter insertion.
Continuous femoral nerve blocks provide potent analgesia and other benefits after knee surgery. Perineural catheter placement techniques using ultrasound guidance and electrical stimulation (ES) have been described, but the optimal method remains undetermined. We tested the hypothesis that ultrasound guidance alone requires less time for femoral perineural catheter insertion and produces equivalent results compared with ES alone. ⋯ Placement of femoral perineural catheters takes less time with ultrasound guidance compared with ES. In addition, ultrasound guidance produces less procedure-related pain and prevents inadvertent vascular puncture.

Randomized Controlled Trial
Ultrasound guidance versus electrical stimulation for infraclavicular brachial plexus perineural catheter insertion.
Electrical stimulation (ES)- and ultrasound-guided placement techniques have been described for infraclavicular brachial plexus perineural catheters but to our knowledge have never been previously compared in a randomized fashion, leaving the optimal method undetermined. We tested the hypothesis that infraclavicular catheters placed via ultrasound guidance alone require less time for placement and produce equivalent results compared with catheters placed solely via ES. ⋯ Placement of infraclavicular perineural catheters takes less time, is more often successful, and results in fewer inadvertent vascular punctures when using ultrasound guidance compared with ES.
