Opioids occupy a position of unsurpassed clinical utility in the treatment of many types of painful conditions. In recent years there has been a noticeable shift regarding the use of opioids for the treatment of both benign and malignancy-related pain. ⋯ Unfortunately, there is a lack of scientifically rigorous studies in this important area, and most information must be derived from anecdotal reports and the personal experience of anesthesiologists working in this field. In this review, we shall discuss current chronic pain management and the impact of opioid use and tolerance on perioperative anesthetic management.

Opioid administration by patient-controlled analgesia (PCA) is the standard therapy for acute postoperative pain. Despite its utility in this setting, limitations of this modality do exist. ⋯ This preprogrammed, self-contained, compact, needle-free system provides pain control superior to that of placebo and comparable to morphine PCA in the first 24 hours after major surgical procedures. The objectives of this article are to describe the method of transdermal iontophoretic medication administration and to review the literature pertaining to the fentanyl ITS.

Randomized Controlled Trial
A randomized, open-label study of once-a-day AVINZA (morphine sulfate extended-release capsules) versus twice-a-day OxyContin (oxycodone hydrochloride controlled-release tablets) for chronic low back pain: the extension phase of the ACTION trial.
The ACTION trial, an open-label, randomized, multicenter, two-part study, compared the efficacy and safety of two sustained-release opioids (SROs), A VINZA (A-MQD), morphine sulfate extended-release capsules given once a day, and OxyContin (O-ER), oxycodone modified-release tablets given twice a day, in subjects with chronic, moderate to severe low back pain. The first part of the study, the evaluation phase, was followed by an optional four-month extension phase aimed at evaluating the long-term stability of pain control, SRO dose, and quality of sleep. ⋯ Both study drugs resulted in significant pain relief and improved sleep in SRO-naive patients with chronic low back pain, and this outcome was attained with a stable daily SRO dose. In patients who completed opioid dose titration, A VINZA performed significantly better than OxyContin in reducing pain scores and improving sleep-with a lower morphine-equivalent daily dose-during both the evaluation and extension phases.

Adequate treatment of patients' pain is a top priority for the World Health Organization (WHO), American Medical Association (AMA), and American College of Emergency Physicians (ACEP), but "adequate" is not clearly defined. Most previous studies of emergency department (ED) pain treatments have centered on musculoskeletal pain in terms of rates of analgesia and disparities in treatment based on race and age. This study will examine complaints of pain other than musculoskeletal and will focus on treatment disparities that may result from differences inpatient and physician characteristics. ⋯ Pain practices in EDs are highly variable and seem inadequate when measured against the goals of WHO, AMA, and ACEP. Patient age, race, and type of pain and the physician's identity, training, and experience all contribute to practice variation. Further research is needed to identify the causes of these variations, and there is a need to develop interventions to standardize and improve pain assessment and treatment.
