Randomized Controlled Trial
Improving needle visualization by novice residents during an in-plane ultrasound nerve block simulation using an in-plane multiangle needle guide.
Ultrasound-guided regional anesthesia with in-plane needle approaches can be challenging due to difficult needle visualization. We hypothesized that an in-plane, multiangle needle guide can help reduce the time it takes novice regional anesthesiologists to perform a simulated ultrasound-guided nerve-targeting procedure and enhance the visualization of the needle. ⋯ A needle guide can help reduce the time needed to complete a simulated nerve targeting procedure and enhance needle visualization for the novice sonographer in a phantom gel simulation. There was no significant reduction in the number of needle passes or in improvement of target approximation noted.

Randomized Controlled Trial
Auricular acupressure for analgesia in perioperative period of total knee arthroplasty.
We examined whether auricular acupressure (AA) can alleviate postoperative pain and decrease narcotic consumption and its adverse effects for osteoarthritis patients after total knee arthroplasty (TKA). ⋯ Applying auricular acupoint acupressure in the perioperative period of TKA is favorable for alleviating postoperative pain, decreasing opioid consumption and its adverse effects, and promoting early rehabilitation. Also, this intervention has the advantage of lower costs, fewer complications, simple application, and high safety.
