Beside the procedures to ensure adequate ventilatory and circulatory support, analgesia, sedation and even anesthesia are essential parts of the preclinical treatment of patients with multiple injuries. The measures for extrication and positioning must be adjusted to minimize pain and excitation. ⋯ The therapy must take into account the special conditions concerning the patient, material and assisting personnel by choosing suitable techniques. The best results can be obtained if all kinds of measures can be administered from the site of the accident on up to the definitive care in the operating room.

At present, intramuscular application of opioids given on request is the most widespread form of postoperative analgesia. This method is widely recognized as often being inadequate, however. As advanced techniques of pain management, such as patient-controlled analgesia, are not generally available, the question arises as to whether non-opioid analgesics should routinely be used in order to improve this situation. ⋯ Despite these results, it must be borne in mind that most studies have been carried out on patients of ASA groups I and II and that conclusions drawn from the literature are not necessarily representative for the elderly and for patients with organ failure. Alternative substances have received relatively little attention. Of these, the pyrazolone derivative, metamizol, may well prove to be of value for patients in whom the use of NSAIDS is contraindicated or relatively ineffective such as after biliary tract surgery.

Sixteen experienced and 15 inexperienced observers watched videotapes showing participants of a back school program perform simple tasks to assess the functional adequacy of their posture. They had received basis or more extensive observer training. Intraclass correlation coefficients were computed as a measure of intra-and interobserver reliability. ⋯ By selecting the most reliable items two alternative measures of overall posture were constructured whose reliability coefficients ranged fromr=0.89 to 0.93 for the group of experienced observers. The reliability of the judgments by the more extensively trained inexperienced observers was also satisfactory. The observation method presented here can thus be regarded as a reliable and potentially valid instrument for assessing the outcome of back school programs.
