The James A. Rand Young Investigator's Award: Battling the Opioid Epidemic with Prospective Pain Threshold Measurement.
Responsible analgesic prescribing is paramount in the opioid epidemic era, yet no standardized protocol exists. We aim to (1) quantify and correlate outpatient opioid need after total knee and hip arthroplasties (TKA and THA) with preoperative objective pain pressure thresholds (PPTs) and subjective pain measures and (2) report incidence of nonsurgical opioid prescriptions 6 weeks postoperatively. ⋯ This novel study demonstrated a statistically significant negative correlation between preoperative pain threshold and outpatient narcotic consumption. Twenty percent of patients received opioid prescriptions outside orthopedic providers in the 6 weeks after surgery highlighting the importance of interdisciplinary communication.

Formulating prescription opioids to limit abuse remains a priority. OROS extended-release (ER) hydromorphone HCl (EXALGO) may have lower abuse potential than many other opioid products. Three postmarketing studies of the relative abuse liability of OROS hydromorphone ER were conducted. ⋯ Abuse of OROS hydromorphone ER was observed in high-risk substance abuse and general population samples but at a very low relative prevalence compared to comparators. Evidence suggests it may be less often abused by alternate ROAs than some comparators. Online data did not find evidence of high levels of desire for OROS hydromorphone ER by recreational abusers. Continued monitoring of this product's abuse liability is warranted.

Nociceptive input during early development can produce somatosensory memory that influences future pain response. Hind-paw incision during the 1st postnatal week in the rat enhances re-incision hyperalgesia in adulthood. We now evaluate its modulation by neonatal analgesia. ⋯ Long-term effects after neonatal injury highlight the need for preventive strategies. Despite effective analgesia at the time of neonatal incision, morphine as a sole analgesic did not alter the somatosensory memory of early-life surgical injury.
