Randomized Controlled Trial Multicenter Study Clinical Trial
Pain management autobiographies and reluctance to use opioids for cancer pain management.
Although pain management education results in improved pain control for some patients, it does not work for all patients because some patients remain reluctant or unwilling to use prescribed analgesics to their optimal effect. In a randomized clinical trial that tested the effectiveness of the PRO-SELF Pain Control Program, 11 patients declined to increase their analgesic use despite moderate to severe pain. These patients were selected for a qualitative analysis of their audiotaped discussions about pain management with their intervention nurses. ⋯ We termed these explanatory accounts pain management autobiographies because of their narrative character and multilayered, richly detailed quality. Pain management autobiographies included stories about (1) previous experience with chronic pain management, including stigmatizing interactions with clinicians and family members; (2) bad experiences with cancer pain management, including severe constipation; and 3) strongly held conventions about medication use, including the belief that all medications are "toxins" that should be avoided. The study findings suggest that a small subset of patients with cancer pain may need interventions such as individual or family counseling or alternative pain management strategies to augment education about opioids.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Ketorolac, diclofenac, and ketoprofen are equally safe for pain relief after major surgery.
Ketorolac is approved for the relief of postoperative pain but concerns have been raised over a possible risk of serious adverse effects and death. Two regulatory reviews in Europe on the safety of ketorolac found the data were inconclusive and lacked comparison with other non-steroidal anti-inflammatory drugs. The aim of this study was to compare the risk of serious adverse effects with ketorolac vs diclofenac or ketoprofen in adult patients after elective major surgery. ⋯ We conclude that ketorolac is as safe as ketoprofen and diclofenac for the treatment of pain after major surgery.

Randomized Controlled Trial Multicenter Study Clinical TrialThe efficacy and safety of three concentrations of levobupivacaine administered as a continuous epidural infusion in patients undergoing orthopedic surgery.
We evaluated the efficacy and safety of three concentrations of levobupivacaine infused epidurally as analgesia for patients undergoing orthopedic procedures. Patients undergoing elective hip or knee joint replacement were enrolled in the study (n = 105). Sensory blockade was established preoperatively with 10-15 mL of 0.75% levobupivacaine. Patients were then randomized to receive 0.0625%, 0.125%, or 0.25% levobupivacaine as a continuous epidural infusion at 6 mL/h for 24 h. IV morphine patient-controlled analgesia was given as rescue analgesia, and time to first request for analgesia and total dose of morphine consumed were recorded. Sensory blockade, motor blockade, visual analog scale pain score, and cardiovascular variables were also recorded at regular intervals postoperatively. Ninety-one patients were included in the primary intent-to-treat analysis. Total normalized dose of morphine, number of patient-controlled analgesia requests, and overall postoperative visual analog scale pain scores were significantly lower for the 0.25% group compared with the other two groups, and the time to first request for rescue analgesia was longer. There was no significant difference between the 0.125% and 0.25% groups in terms of maximum motor blockade achieved and time to minimal motor blockade. Safety data were equivalent among the three groups. We conclude that levobupivacaine as a continuous epidural infusion provided adequate postoperative analgesia and that the 0.25% concentration provided significantly longer analgesia than 0.125% or 0.0625% levobupivacaine without any significant increase in detectable motor blockade relative to the 0.125% group. ⋯ Postoperative epidural infusion of levobupivacaine can provide safe and effective analgesia for patients having hip or knee joint replacement. Of the three concentrations we infused at a constant rate, 0.25% provided significantly better pain relief.

Randomized Controlled Trial Multicenter Study Clinical TrialTramadol/acetaminophen combination tablets for the treatment of osteoarthritis flare pain: a multicenter, outpatient, randomized, double-blind, placebo-controlled, parallel-group, add-on study.
In a flare of osteoarthritis (OA) pain, increasing the dose of standard anti-inflammatory or routine analgesic drugs may not be practical because of an increased incidence of side effects. In patients achieving inadequate pain relief from traditional non-steroidal anti-inflammatory drugs (NSAIDs) or cyclooxygenase (COX)-2-selective inhibitors, it may be appropriate to add an analgesic agent with a different mechanism of action, thereby targeting multiple components of the pain pathway. ⋯ In this study, addition of tramadol/acetaminophen to NSAID or COX-2-selective inhibitor therapy was well tolerated and effective in the treatment of OA flare pain.

Randomized Controlled Trial Multicenter Study Clinical Trial
Valdecoxib, a COX-2-specific inhibitor, is an efficacious, opioid-sparing analgesic in patients undergoing hip arthroplasty.
Opioid agents are highly effective analgesics after orthopedic surgery but are associated with several adverse effects. Valdecoxib is a new, highly selective cyclooxygenase (COX)-2-specific inhibitor with a rapid onset of action and significant analgesic properties that is being developed for the management of acute pain. The objective of this study was to demonstrate the opioid-sparing efficacy of valdecoxib as part of a multimodal treatment of pain associated with hip arthroplasty. ⋯ Valdecoxib and placebo were equally well tolerated. Pre- and postoperative administration of valdecoxib reduces the amount of morphine required for postoperative pain relief and provides greater analgesic efficacy compared with morphine alone. Thus, valdecoxib has significant clinical utility for acute pain management in orthopedic surgery patients.
