Opioid-related respiratory and gastrointestinal adverse events in patients with acute postoperative pain: prevalence, predictors, and burden.
Opioid-induced respiratory depression (OIRD) and postoperative nausea and vomiting (PONV) are challenging, resource-intensive, and costly opioid-related adverse events (ORAEs). Utilizing the Premier Healthcare Database, we identified patients > 18 years old, who underwent at least one surgical procedure of interest (i.e., cardiothoracic/vascular, general/colorectal, obstetric/gynecologic, orthopedic, or urologic), and received at least one dose of intravenous morphine, hydromorphone, or fentanyl for acute postoperative pain. The incidence of OIRD and PONV using ICD-9 codes, factors influencing these AEs, length of stay (LOS) and related costs were analyzed. ⋯ Increased odds of PONV were associated with younger age, female sex, and major disease severity. When respiratory depression or nausea/vomiting was present versus absent, LOS was significantly longer, and hospital costs were higher. In this analysis, OIRD and PONV were more prevalent than previously reported, were associated with identifiable risk factors, and had substantial effects on resource utilization and costs.

Bilateral deficits in sensorimotor function have been observed in unilateral musculoskeletal pain conditions. Evidence suggests a reduction in interhemispheric inhibition (IHI) from the "affected" (contralateral to the side of pain) to the "unaffected" primary motor cortex (M1) could contribute. However, the effect of short-lasting acute muscle pain on IHI, and whether any changes are related to early sensorimotor changes in the unaffected limb, is unknown. ⋯ These findings suggest a decrease in IHI from the affected to the unaffected M1 that occurs rapidly after the onset of acute pain and could contribute to the development of bilateral symptoms. PERSPECTIVE: The affected M1 (contralateral to the side of pain) releases inhibition over the unaffected M1 within minutes after the onset of acute muscle pain. This finding could have relevance for the development of bilateral sensorimotor symptoms in unilateral pain conditions.

Tactile precision remains intact when acute neck pain is induced.
A growing body of evidence suggests that chronic pain is associated with perceptual changes, such as impaired tactile acuity and laterality judgements. A recent study on low back pain showed that tactile acuity was decreased immediately after acute pain induction. Biologically, acute pain should lead to enhanced rather than disruptive changes in tactile acuity to meaningfully respond to potentially damaging nociceptive stimuli. ⋯ PERSPECTIVE: In this study, a sensory adaptation to acute neck pain was investigated. It was found that experimental neck pain did not elicit changes in the sensory axis, leaving tactile acuity intact in otherwise healthy participants. These data support site-specific sensory adaptation to pain.

In response to the growing opioid crisis, Florida recently implemented a law restricting the duration of opioid prescriptions for acute pain. Little is known about the impact of such legislation on opioid prescription practices at the time of discharge after surgery. The objective of this study was to determine whether Florida's new legislation changed opioid prescription practices for analgesia after surgery. ⋯ Opioid prescriptions for patients undergoing common outpatient surgical procedures at a large public university-affiliated hospital in Florida were substantially reduced within 6 months after implementation of state legislation limiting the duration of opioid prescriptions. This reduction was not associated with an increase in the number of postoperative emergency department visits. The legislation should significantly decrease the amount of unused opioid pills potentially available for diversion and abuse. Secondary effects from the enactment of this law remain to be evaluated.
