Dialysis access creation is a common outpatient procedure that can be completed using general, regional, or local anesthetic techniques. There are few endorsed guidelines regarding opioid-based pain control following fistula creation. The purpose of this study was to determine whether utilization of regional anesthesia (RA) is associated with the decreased use of narcotics postoperatively. ⋯ Morbidity and mortality related to opiate use continues to be a public health issue in the United States. This study demonstrates that regional anesthetic techniques in comparison to general anesthesia can result in a significant decrease in postoperative opiate consumption.

Misuse of prescription opioids is a public health crisis in the United States. In 2016, it was estimated that 3.3 million Americans were misusing prescription opioids (SAMHSA, 2017) and nearly 63,632 deaths were due to prescription opioid misuse. From 1999 to 2010, the number of prescription opioid drugs sold to health care facilities from pharmaceutical companies, nearly quadrupled. Cesarean delivery is the most common surgical procedure performed in the United States and opioids are most often chosen to manage post-operative pain. Research has shown that women, who deliver via cesarean section, are prescribed an excess of opioid tablets upon discharge and often store them in unsecure locations. Furthermore, the vast majority, are not disposed of properly. ⋯ Engaging post-operative patients in decisions regarding pain management, educating women on multi-modal methods to manage pain, and providing women with a means to properly dispose of excess tablets, can reduce opioid tablets available for misuse and diversion in the community.

Postoperative pain is a common clinical problem that, in preclinical studies, has almost exclusively been studied in males. Altered C-fibre activity-dependent slowing (ADS) is a potential underlying mechanism, given it is altered after tissue inflammation and nerve injury, but this has not been explored post-incision. We therefore investigated the effect of hind-paw incision on C-fibre ADS in both sexes and the involvement of voltage-gated sodium channels (NaV) as they contribute to ADS. We also assessed mechanical and thermal sensitivity post-incision in both sexes. ⋯ Hind-paw incision induces sex-dependent changes in C-fibre activity-dependent slowing, which likely contribute to the observed sex difference in peak thermal hypersensitivity. This may reflect sex- and incision-induced differences in functional expression of NaV channels that differs by C-fibre subtype.

Observational Study
Association of Pre-operative Functional Disability with Chronic Postsurgical Pain: A Prospective Observational Study.
Chronic postsurgical pain negatively affects postoperative recovery. We aimed to assess the association between preoperative functional disability and chronic postsurgical pain. ⋯ Our study showed that in patients who undergo elective abdominal surgery, 12% with preoperative functional disability experience chronic postsurgical pain after 1 year. Preoperative functional disability is associated with chronic postsurgical pain, use of preoperative pain medications and acute postoperative pain. Patients with preoperative functional disability have higher pain numerical rating scale scores at any postoperative measurement point.
