Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Postoperative pain control following remifentanil-based anaesthesia for major abdominal surgery.
Eighty patients undergoing major abdominal surgery using remifentanil-based anaesthesia were randomly allocated in a double-blind manner to receive an intravenous bolus of fentanyl, buprenorphine, morphine or piritramide 20 min before the end of surgery. A reduced dose was administered postoperatively when patients reported moderate pain. Subsequent analgesia was provided by patient-controlled analgesia (PCA). ⋯ At first pain assessment, 63% of patients reported no or mild pain; 80% of patients required the second opioid bolus, those receiving piritramide needed the bolus significantly later than patients receiving buprenorphine or fentanyl. First PCA requirement also occurred significantly later in the piritramide group. This technique provided effective postoperative pain relief and transition to routine PCA and did not compromise recovery.

Multicenter Study Clinical Trial
A drug use evaluation of selected opioid and nonopioid analgesics in the nursing facility setting.
To determine the medical conditions for which selected analgesics are most frequently prescribed in nursing facilities (NFs), describe the use of pharmacologic and nonpharmacologic pain therapies, and determine the frequency and quality of pain assessment in NF residents. ⋯ The findings show a lack of adequate pain assessments, little use of nonpharmacologic interventions, and inappropriate use of analgesic medication. The small percentage of residents with chronic pain assessed objectively suggests the difficulty of monitoring pain progression in NFs. The prescribing of analgesic for most residents (with propoxyphene used most often, long-acting opioids used infrequently, and frequent prn use) was inconsistent with recommended pain therapy in older people and attests to the urgent need to educate NF practitioners on the appropriate use of analgesics.

Multicenter Study
[Clinical evaluation of the efficacy of the paracetamol and caffeine combination in the treatment of tension headache].
Tension type headache in both its forms, episodic and chronic, is the most common type of headache experienced by the population. The headache attack or the prevention of new crises may be treated with pharmacological as well as non-pharmacological measures. This study included 5,490 patients from out-patient clinics and medical offices covering various regions of Brazil. ⋯ Good/excellent efficacy ratings were achieved in 61.93%/37.80% of the cases according to the physician's assessment and in 48.51%/40.29% according to the patients' assessment. Adverse events, commonly gastrointestinal manifestations, were reported by 5.57% of the patients. This is a Brazilian study of the efficacy and safety of the combined use of acetaminophen-caffeine for the treatment of tension type headache.

Multicenter Study Clinical TrialConstipation and the use of laxatives: a comparison between transdermal fentanyl and oral morphine.
Constipation and the use of laxatives were investigated in patients with chronic cancer pain treated with oral morphine and transdermal fentanyl in an open sequential trial. Forty-six patients were treated with slow-release morphine 30-1000 mg/day for 6 days and 39 of these patients were switched to transdermal fentanyl 0.6-9.6 mg/day with a conversion ratio of 100:1. Median fentanyl doses increased from 1.2 to 3.0 mg/day throughout the 30-day transdermal treatment period. ⋯ Lactulose was used mainly and was reduced most drastically, but other laxatives were also used less frequently. In this study transdermal fentanyl was associated with a significantly lower use of laxatives compared to oral morphine. The difference in the degree of constipation between the two analgesic regimens should be confirmed in a randomized double-blind study that takes into account both constipation and use of laxatives.

Randomized Controlled Trial Multicenter Study Clinical TrialMaintenance of the long-term effectiveness of tramadol in treatment of the pain of diabetic neuropathy.
The objective of this study was to evaluate the efficacy and safety of tramadol in a 6-month open extension following a 6-week double-blind randomized trial. ⋯ Tramadol provides long-term relief of the pain of diabetic neuropathy.
