Abstract
BACKGROUND: The treatment of severe pain is one of the basic procedures of emergency medicine. In rural regions, longer arrival times of the emergency doctor prevent the earliest possible treatment of pain. Since 2014, a project for independent analgesia by ambulance personnel has been introduced in our ambulance service area. METHODS: Over a period of 7 years the mission protocols were recorded and statistically evaluated within the framework of an observational study. Among other things, the attendance and transport times, vital signs, pain level, symptom groups (body region) and classification according to disease or accident mechanism were recorded. Treatment data by medication, including dosages, were recorded for fentanyl (monotherapy), morphine (monotherapy) and a combination (change from morphine to fentanyl, additional application of esketamine, metamizole or butylscopolamine). RESULTS: In 659 patients, the opioids fentanyl and morphine were used by the ambulance staff, 596 data sets could be evaluated. When an emergency physician was requested, the average time of presence at the scene was 34.8 +- 11.7 min, in cases of unavailability it was 29.0 +-9.8 min (p<0.0001). Analgesic therapy resulted in a reduction of pain from NRS 8.4 (+-1.3) to NRS 3.5 +-1.8 (p<0.0001). Pain intensity after treatment by emergency paramedics compared to emergency physicians was not significantly different with NRS 3.5 +- 1.7 versus NRS 3.6 +-1.9 (p=0.788). Fentanyl was used at a mean dose of 0.18mg +- 0.11 and morphine at a mean dose of 4.4mg +- 3.6mg. There was no clinically relevant decrease in oxygen saturation or respiratory rate in any of the treatment groups. Antagonisation of the opioid effect with naloxone was not necessary in any case. CONCLUSION: Analgesia with morphine and fentanyl by specially trained ambulance personnel according to defined rules of use is a safe and necessary procedure for patients, especially in rural regions.
