Akzidentelle Hypothermie in häuslicher Umgebung

[Neglected, lonely and sick - the social breakdown : A special patient group in the emergency department]

BACKGROUND

The emergency department (ED) is increasingly becoming the primary care unit of patients who are no longer able to meet the necessary minimum requirements for a healthy life. In the emergency medical care of these patients, fixation errors and stereotyped thinking can distract from serious illnesses, which can be tended by emergency medicine. This group of patients, with their multifactorial problems, represents a special challenge for the staff of the ED. The aim of this study is to improve the quality of the care for a special patient group.

MATERIALS AND METHODS

A monocentric retrospective observation study was conducted at the University Hospital Bonn (UKB). On the basis of case studies, the emergency medical care of this special patient group was examined in the ED.

RESULTS

Over the period of 7 years (2009 to 2016), 17 patients in a state of total neglect could be examined. The endpoints identified, during the emergency care, are the therapy of life-threatening diseases, laboratory pathologies, introduction of infectious protective measures, initiation of diagnostic measures, measures to be initiated within different departments (operating room, intensive care unit) and outcome.

CONCLUSION

Patients in a state of total neglect require interdisciplinary primary care at a hospital with extended care structures. The apparent primary impression of these patients must not lead to a fixation error. Due to the often not obtainable history of the patient's and the complex appearance of these patients, the evaluation should be carried out according to a defined algorithm in the emergency room.

Patients' experiences of cold exposure during ambulance care

Background

Exposure 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.

Method

During 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.

Results

In 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.

Conclusion

Cold 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.

[Water rescue. A unique area of emergency medicine with many facets]

Emergencies on or in water are relatively rare in the rescue service. For this reason, water accident treatment and management does not receive much attention in the training of emergency medicine physicians. Consequently doctors working in emergency medicine often have minimal knowledge in this area. On the other hand, the number of fatal accidents on and in water has increased in recent years. In Germany the number of non-swimmers is also increasing, so it can be assumed that the number of water-related accidents will continue to rise. Drowning accidents and near drowning are important in this context and will be discussed in detail in this review as well as hypothermia (a frequent problem), accompanying injuries and diving accidents.

[Management of accidental hypothermia]

Patients with hypothermia are frequently encountered in emergency medicine. Particularly trauma patients, but also other predisposed persons, can be expected to suffer from hypothermia at any time of the year. Therapy focuses not only on symptom-oriented intensive care to stabilize and secure vital functions, but also on rewarming. Even in cases of severe hypothermia with circulatory arrest, therapy can produce excellent results. This paper first gives a brief overview of the typical clinical symptoms of hypothermia, before giving a detailed description of the preclinical and in-hospital management of the hypothermia patient. The various rewarming strategies are the subject of special attention and critical evaluation.

Der Lawinennotfall

In North America and Europe around 140 persons die every year due to avalanches, approximately 35 in North America, 100 in the European Alps, and 5 in other parts of Europe. Most of the victims are skiers and snowboarders. This article outlines the specific pathophysiology of avalanche burials, such as hypoxia, hypercapnia, and hypothermia and also other factors which influence survival. Strategies to minimize the mortality due to avalanches and the on-site treatment of buried persons are discussed. Finally, possibilities to reduce the number of avalanche deaths are pointed out.
