Pathogenesis of porcine Actinobacillus pleuropneumonia: Part I. Effects of surface components of Actinobacillus pleuropneumoniae in vitro and in vivo

The aim of this study was to evaluate the quality of pain management in prehospital emergency care and to get more information about the administration of analgesics in prehospital patients. METHODS: Patients with painful diseases or injuries who had been brought to Munich hospital's were included in the study. Immediately after having reached the hospitals' emergency department, they were evaluated using a 101-point visual analogue scale for the severity of pain at four predefined periods. Information about the patient, the diagnosis, and the analgesic treatment used by the emergency teams were drawn from the patient's chart. RESULTS: A total of 462 patients were included in the study. The mean pain score on arrival of the emergency team was 64 points; 36.5% of the patients were treated with analgesics. In 28.1% the emergency team tried to reduce pain through external measures (i.e., setting of fractures). In 35.3% there was no therapeutic intervention. In cases in which analgesic therapy was initiated, a definite reduction in pain was achieved during emergency care. Visual analogue scores decreased from 70 points at the beginning to 29 points at arrival to the hospital's emergency department. Analgesics were most frequently used for patients with cardiopulmonary diseases (47.2%), followed by patients with traumatic accidents (35.5%) and patients with acute abdominal pain (25.2%). Of the analgesics, opioids were given most frequently (87.0%). Nonopioid analgesic agents were used in 32.1%. The results of our investigation demonstrate that in many cases the administration of analgesics is not individualized to the patients needs. CONCLUSION: During the prehospital period of emergency care many patients suffer from severe pain. The development of patient-oriented concepts concerning pain management could contribute to improvement of pain therapy in prehospital emergency medicine.
