Randomized Controlled Trial
Randomized study of teaching ultrasound-guided vascular cannulation using a phantom and the freehand versus needle guide-assisted puncture techniques.
The task of ultrasound-guided vessel cannulation can be technically difficult. Needle guides have been designed to facilitate vessel puncture. We aimed to identify and compare the learning curves of participants performing vessel puncture with conventional freehand (FH) and needle guide-assisted (NG) techniques. ⋯ The NG puncture allows a greater number of trainees to cross the learning threshold and offers the advantages of fewer posterior-wall punctures and skin punctures. The use of NG puncture may result in a shorter path to proficiency, allowing trainees to attempt needle puncture earlier and with a greater degree of safety.

Randomized Controlled Trial
Determination of steroid injection sites using lidocaine test in adhesive capsulitis: A prospective randomized clinical trial.
To validate the usefulness of subacromial bursa lidocaine for determination of the therapeutic steroid injection site in patients with adhesive capsulitis ⋯ We found that subacromial lidocaine injection prior to steroid injection resulted in better improvement of pain than conventional GH injection for patients with adhesive capsulitis.

Randomized Controlled Trial
Procedural sedation and analgesia as an adjunct to periprostatic nerve block for prostate biopsy: A prospective randomized trial.
To assess whether patient comfort could be increased by adding procedural sedation and analgesia (PSAA) to periprostatic nerve block (PNB) in patients undergoing transrectal ultrasound-guided prostatic biopsy (TRUS-PB). ⋯ PSAA with midazolam and remifentanil used as an adjunct to the standard PNB is safe and effective during TRUS-PB. Patients undergoing PSAA in addition to PNB experienced significantly less pain and higher satisfaction scores than did those given PNB alone.

Randomized Controlled Trial Comparative Study
Ultrasound versus palpation guidance for intra-articular injections in patients with degenerative osteoarthritis of the elbow.
The aim of this study is to evaluate the accuracy rate of ultrasound (US) -guided intra-articular (IA) injections in patients by posterior approach with osteoarthritis (OA) of the elbow. ⋯ US-guided IA elbow injections by posterior approach may raise the accuracy rate in elbow joint injections.

Randomized Controlled Trial Comparative Study
Accuracy of blind versus ultrasound-guided suprapatellar bursal injection.
To compare the accuracy rates between ultrasound (US)-guided and blind knee intra-articular injection via the suprapatellar bursa. ⋯ Intra-articular injections through the suprapatellar bursa under US guidance increased the accuracy of knee joint injections.
