Randomized Controlled TrialMigration rate of proximal adductor canal block catheters placed parallel versus perpendicular to the nerve after total knee arthroplasty: a randomized controlled study.
Perineural catheters placed parallel to the nerve course are reported to have lower migration rates than those placed perpendicular to it. However, catheter migration rates for a continuous adductor canal block (ACB) remain unknown. This study compared postoperative migration rates of proximal ACB catheters placed parallel and perpendicular to the saphenous nerve. ⋯ Parallel placement of the ACB catheter provided a lower postoperative catheter migration rate than perpendicular placement of the ACB catheter along with corresponding improvements in ROM and secondary analgesic outcomes.

There remains a role for neuraxial anesthesia for hip fracture surgery in the post-REGAIN era.
Two recent, large-scale, randomized controlled trials comparing neuraxial anesthesia with general anesthesia for patients undergoing surgical fixation of a hip fracture have sparked interest in the comparison of general and neuraxial anesthesia. These studies both reported non-superiority between general and neuraxial anesthesia in this patient cohort, yet they have limitations, like their sample size and use of composite outcomes. We worry that that if there is a perception among surgeons, nurses, patients and anesthesiologists that general and spinal anesthesia are equivalent (which is not what the authors of the studies conclude), it may become difficult to argue for the resources and training to provide neuraxial anesthesia to this patient population. In this daring discourse, we argue that despite the recent trials, there remain benefits of neuraxial anesthesia for patients who have suffered hip fractures and that abandoning offering neuraxial anesthesia to these patients would be an error.

Case ReportsAcute pain service reduces barriers to buprenorphine/naloxone initiation by using regional anesthesia techniques.
Medications for opioid use disorder (MOUD) are a life-saving intervention; thus, it is important to address barriers to successful initiation. Spasticity affects many patients with spinal cord injury and can be painful and physically debilitating. Chronic painful conditions can lead to the illicit use of non-prescribed opioids, but fear of pain is a barrier to the initiation of MOUD. In this case report, we describe the novel use of botulinum toxin A injections to treat abdominal spasticity and facilitate Acute Pain Service-led buprenorphine/naloxone initiation in a patient with opioid use disorder and severe abdominal spasticity due to spinal cord injury. ⋯ This case report demonstrates that inpatient buprenorphine/naloxone initiation by an Acute Pain Service can improve the success of treatment by addressing barriers to initiation. Acute Pain Service clinicians possess unique skills and knowledge, including ultrasound-guided interventions, that enable them to provide innovative and personalized approaches to care in the complex opioid use disorder population.

Association of race and receipt of regional anesthesia for hip fracture surgery.
There is evidence suggesting clinical benefits of regional anesthesia use in the setting of hip fracture repair, including reduced risk of death, deep vein thrombosis, pulmonary complications and myocardial infarction. Thought the literature is mixed, the use of regional anesthesia in hip fracture surgery has not been studied for racial differences. We examined the association of race with neuraxial anesthesia and regional blocks in patients undergoing hip fracture surgery. ⋯ The study suggests that racial differences exist with the utilization of regional anesthesia for hip fracture surgery. While the results of this study should not be taken as evidence for healthcare disparities, it could be used to support hypotheses for future studies that aim to investigate causes of disparities and corresponding patient outcomes.
