Randomized Controlled Trial Comparative Study
Erector spinae plane block versus quadratus lumborum block for postoperative analgesia after laparoscopic nephrectomy: A randomized controlled trial.
We compared the analgesic effects of erector spinae plane block versus quadratus lumborum block following laparoscopic nephrectomy. ⋯ Compared with quadratus lumborum block, erector spinae plane block provided better analgesia as manifested by lower opioid consumption and pain intensity for up to 24 h after laparoscopic nephrectomy.

The prescription of opioid analgesics for trigeminal neuralgia (TN) is controversial, and their effect on postoperative outcomes for patients with TN undergoing microvascular decompression (MVD) has not been reported. We aimed to describe the relationship between preoperative opioid use and postoperative outcomes in patients with TN undergoing MVD. ⋯ Preoperative opioid use in the setting of TN is associated with worse pain outcomes and increased risk for pain recurrence after MVD. These results indicate that opioids should be prescribed cautiously for TN and that worse post-MVD outcomes may occur in patients using opioids preoperatively.

Misuse of prescription opioids is a well-established contributor to the US opioid epidemic. The primary objective of this study was to identify which level of care delivery (ie patient, prescriber, or hospital) produced the most unwarranted variation in opioid prescribing after common surgical procedures. ⋯ Given the large proportion of unexplained variation observed at the provider level, targeting prescribers through education and training may be an effective strategy for reducing postoperative opioid prescribing.

Sedoanalgesia With Ketamine in the Emergency Department: Factors Associated With Unsatisfactory Effectiveness.
Ketamine is a safe and widely used sedative and analgesic in children. The purpose of this study is to evaluate the response to sedoanalgesia for painful procedures in the pediatric emergency department. ⋯ This study concludes that intravenous/intranasal ketamine can provide safe and successful analgesia in pediatric patients in the ED. At intravenous doses of 1-1.5 mg/kg, good effectiveness was achieved in almost 90% of cases. Arthrocentesis had the highest percentage of unsatisfactory results. Repeat dosing should be considered for procedures longer than 20 minutes.

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.
