Evaluation of a task-specific checklist and global rating scale for ultrasound-guided regional anesthesia.
Checklists and global rating scales (GRSs) are used for assessment of anesthesia procedural skills. The purpose of this study was to evaluate the reliability and validity of a recently proposed assessment tool comprising a checklist and GRS specific for ultrasound-guided regional anesthesia. ⋯ This is the first study to evaluate the reliability and validity of a combined checklist and GRS for ultrasound-guided regional anesthesia using multiple observers and taking into account both absolute agreement and correlation in determining the ICC of 0.44 for interrater reliability. There was evidence to support construct validity.

ReviewPerioperative Research Fellowship: Planning, Implementation, Experience.
Perioperative outcomes research has gained widespread interest and is viewed as increasingly important among different specialties, including anesthesiology. Outcomes research studies serve to help in the adjustment of risk, allocation of resources, and formulation of hypotheses to guide future research. ⋯ This article was intended to describe the curriculum and implementation of the Perioperative Medicine and Regional Anesthesia Research Fellowship at the Hospital for Special Surgery. We also proposed a method to evaluate the success of a research fellowship curriculum.

Intraneural or Extraneural: Diagnostic Accuracy of Ultrasound Assessment for Localizing Low-Volume Injection.
When one is performing ultrasound-guided peripheral nerve blocks, it is common to inject a small amount of fluid to confirm correct placement of the needle tip. If an intraneural needle tip position is detected, the needle can then be repositioned to prevent injection of a large amount of local anesthetic into the nerve. However, it is unknown if anesthesiologists can accurately discriminate intraneural and extraneural injection of small volumes. Therefore, this study was conducted to determine the diagnostic accuracy of ultrasound assessment using a criterion standard and to compare experts and novices in ultrasound-guided regional anesthesia. ⋯ Discrimination of intraneural or extraneural needle tip position based on an injection of 0.5mL is possible, but even experts missed 1 of 6 intraneural injections. In novices, the sensitivity of assessment was significantly lower, highlighting the need for focused education.
