The aim of this study was to evaluate a new modified visual analog scale, called the dolorimeter, together with a verbal rating scale (VRS) and a linear visual scale (VAS), in the measurement of acute postoperative pain. The scales were evaluated with reference to their sensitivity, reliability and validity, and correlation. During the study 200 patients 11-70 years of age (125 men, 75 women) were interviewed after orthopedic surgery to ascertain the intensity of the pain. ⋯ On the other hand, the high sensitivity of the two analog scales which patients can use to determine their individual pain intensity proved to be much more sensitive. All three methods correlated statistically; the highest correlation coefficients were found between the analog scales VAS and the dolorimeter. Because the dolorimeter is clearly preferred to the other methods, especially by elderly patients, we came to the conclusion that the dolorimeter is less abstract than the VAS and more practical to handle.

Sufentanil, an opioid analgesic, is an analogue of fentanyl, and has been used for the induction and maintenance of anaesthesia, and for postsurgical analgesia. It has shorter distribution and elimination half-lives, and is a more potent analgesic than fentanyl. In clinical practice, however, intravenously administered sufentanil produces essentially equivalent anaesthesia to fentanyl and is a better anaesthetic than morphine or pethidine (meperidine) for major surgery. ⋯ Epidural sufentanil produces a more rapid onset and better initial quality of analgesia than morphine, buprenorphine or hydromorphine when administered postoperatively, but the duration of analgesia is shorter. Thus, sufentanil's primary place in therapy at this time would appear to be as high dose anaesthesia for major surgery such as cardiac surgery, and as low dose supplement to balanced anaesthesia in general surgery. In addition, low doses administered epidurally seem to have a potential role for analgesia during labour or after surgery although further studies are required to clarify this situation.

We have attempted to dispel many of the myths and misconceptions surrounding the use of narcotic analgesics in the treatment of childhood pain. Our hope is that an improved understanding and the application of effective, safe therapy will minimize the suffering of the child with acute or chronic pain.

Randomized Controlled Trial Clinical Trial
[Patient-controlled analgesia. A technical toy or a contribution to the treatment of pain?].
PCA (patient-controlled analgesia) was used to treat postoperative pain after general surgery and gynecological operations in a total of 82 patients. In a prospective randomized study, 20 of these patients received pentazocine and 20 were treated with Fentanyl. The bolus quantity for pentazocine was 15 mg in 5 ml NaCl, and that for Fentanyl 0.05 mg in 5 ml NaCl. ⋯ The majority of patients reported very positive experience with PCA. There were few side effects. Problems arose from the negative attitude of other doctors and the nursing staff, and from some misunderstandings.(ABSTRACT TRUNCATED AT 250 WORDS)
