Anesthesia start time documentation accuracy where peripheral nerve block is the primary anesthetic.
When used as the primary anesthetic, nerve blocks are not billed as separate procedures. In this scenario, the anesthesia start (AStart) time should include the block procedural time. We measured how often AStart time was documented before the nerve block was placed in the preoperative area, and compared cases where a block team performed the nerve block and cases where the intraoperative anesthesia attending supervised the nerve block. We hypothesized that the involvement of a regional anesthesia team would lead to more accurate documentation of AStart. We also estimated the lost revenue due to inaccurate start time documentation. ⋯ The performance of primary regional anesthesia procedure by a block team increased the incidence of inaccurate documentation and uncaptured potential revenue. There is need for education about accurate nerve block documentation for anesthesiologists, especially when separate teams are used.

Randomized Controlled Trial
The potentiating effect of intravenous dexamethasone upon preemptive pudendal block analgesia for hypospadias surgery in children managed with Snodgrass technique: a randomized controlled study : Dexamethasone for pain management in children.
Evidence regarding the potentiating effects of intravenous dexamethasone on peripheral regional anesthesia in children is sparse. The objective of the current study was to investigate the potentiating effect of intravenous dexamethasone upon pudendal block during surgical correction of hypospadias using Snodgrass technique. ⋯ dexamethasone has been found to potentiate analgesia obtained with regional anesthesia in children. B. WHAT THIS ARTICLE ADDS: intravenous dexamethasone was found to improve analgesia with a preemptive pudendal block during hypospadias surgery. C. IMPLICATIONS FOR TRANSLATION: results of this study indicate that intravenous dexamethasone could be used as an adjunct to pudendal block.

Tendon injury produces intractable pain and disability in movement, but the medications for analgesia and restoring functional integrity of tendon are still limited. In this study, we report that proteinase-activated receptor 2 (PAR2) activation in dorsal root ganglion (DRG) neurons contributes to chronic pain and tendon histopathological changes produced by Achilles tendon partial transection injury (TTI). Tendon partial transection injury increases the expression of PAR2 protein in both somata of DRG neurons and their peripheral terminals within the injured Achilles tendon. ⋯ Vitamin B complex (VBC), containing thiamine (B1), pyridoxine (B6), and cyanocobalamin (B12), is effective to ameliorate TTI-induced pain, inhibit ectopic nerve sprouting, and accelerate tendon repair, through suppressing PAR2 activation. These findings reveal a critical role of PAR2 signaling in the development of chronic pain and histopathological alterations of injured tendon following Achilles tendon injury. This study suggests that the pharmaceuticals targeting PAR2, such as VBC, may be an effective approach for the treatment of tendon injury-induced pain and promoting tendon repair.
