BackgroundExposure to cold temperatures is often a neglected problem in prehospital care. Cold exposure increase thermal discomfort and, if untreated causes disturbances of vital body functions until ultimately reaching hypothermia. It may also impair cognitive function, increase pain and contribute to fear and an overall sense of dissatisfaction. The aim of this study was to investigate injured and ill patients’ experiences of cold exposure and to identify related factors.MethodDuring January to March 2011, 62 consecutively selected patients were observed when they were cared for by ambulance nursing staff in prehospital care in the north of Sweden. The field study was based on observations, questions about thermal discomfort and temperature measurements (mattress air and patients’ finger temperature). Based on the observation protocol the participants were divided into two groups, one group that stated it was cold in the patient compartment in the ambulance and another group that did not. Continuous variables were analyzed with independent sample t-test, paired sample t-test and dichotomous variables with cross tabulation.ResultsIn the ambulance 85% of the patients had a finger temperature below comfort zone and 44% experienced the ambient temperature in the patient compartment in the ambulance to be cold. There was a significant decrease in finger temperature from the first measurement indoor compared to measurement in the ambulance. The mattress temperature at the ambulance ranged from −22.3°C to 8.4°C.ConclusionCold exposure in winter time is common in prehospital care. Sick and injured patients immediately react to cold exposure with decreasing finger temperature and experience of discomfort from cold. Keeping the patient in the comfort zone is of great importance. Further studies are needed to increase knowledge which can be a base for implications in prehospital care for patients who probably already suffer for other reasons.

BackgroundExposure to cold temperatures is, often, a neglected problem in prehospital care. One of the leading influences of the overall sensation of cold discomfort is the cooling of the back. The aim of this study was to evaluate the effect of a heated ambulance mattress-prototype on body temperatures and thermal comfort in an experimental study.MethodData were collected during four days in November, 2011 inside and outside of a cold chamber. All participants (n = 23) participated in two trials each. In one trial, they were lying on a stretcher with a supplied heated mattress and in the other trial without a heated mattress. Outcomes were back temperature, finger temperature, core body temperature, Cold Discomfort Scale (CDS), four statements from the state-trait anxiety – inventory (STAI), and short notes of their experiences of the two mattresses. Data were analysed both quantitatively and qualitatively. A repeated measure design was used to evaluate the effect of the two mattresses.ResultsA statistical difference between the regular mattress and the heated mattress was found in the back temperature. In the heated mattress trial, the statement “I am tense” was fewer whereas the statements “I feel comfortable”, “I am relaxed” and “I feel content” were higher in the heated mattress trial. The qualitative analyses of the short notes showed that the heated mattress, when compared to the unheated mattress, was experienced as warm, comfortable, providing security and was easier to relax on.ConclusionsHeat supply from underneath the body results in increased comfort and may prevent hypothermia which is important for injured and sick patients in ambulance care.

Background Nurses working in prehospital emergency care (PEC) encounter patients with all types of health conditions. Increasingly, they are encountering patients suffering from mental illness and this trend reflects the worldwide increase in mental illness. There is very little current knowledge of encounters between nurses and patients with mental illness in ‘PEC’, especially from the nurses’ perspectives. Aim The aim of the study is to investigate nurses’ experiences of encountering patients with mental illness in ‘PEC’. Methods The participants were recruited in a region in southeast Sweden (that covers approximately 5600 km2 and has 300,000 inhabitants). In total, 17 nurses consented to participate. The participants were asked to narrate their individual experience of encountering patients with mental illness. The interviews were transcribed verbatim, then analysed with qualitative content analysis. Results The result is presented in terms of three themes and eight sub-themes. The main themes are ‘Lacking trust in the patient and one’s own abilities’, ‘Being under internal and external influences’ and ‘Moving towards a genuine nurse-patient relationship’. Conclusion The results show that nurses strive to lay the foundation for a trusting relationship. Simultaneously nurses encountering is characterized by a mistrust and it is influenced by pre-understanding and emotions when they take care for patients. The findings could be used to develop nurses’ readiness and capability to encounter patients with mental illness and to respond appropriately to the patients somatic and mental care needs.
