Zusammenfassung
Eine akzidentelle Hypothermie ist nicht nur im Winter, sondern im Rettungsdienst ganzjährig zu erwarten. Von einer Hypothermie spricht man, wenn die Körperkerntemperatur (KKT) unter 35 °C abfällt. Die Ursachen für eine akzidentelle Hypothermie sind vielfältig und reichen von einer Exposition und äußere Faktoren über Intoxikationen bis hin zu Ertrinken und Verschüttung unter Schnee.
Abstract
Not only during the winter with low temperatures in the environment or in alpine regions, but also in the year-round emergency medical service hypothermic patients must be expected. Hypothermia is classified into 4 clinical severities. In emergency services, body temperature is to be measured if hypothermia is suspected (usually in-ear measurement). Special procedure is required in a resuscitation situation. Cave: Preclinically, the diagnosis of cardiac arrest on a hypothermic patient can be difficult. First of all, the patient has to be reheated during resuscitation. Medication and possible defillibration has to be adjusted to the body temperature. Before ending the reanimation keep in mind: “No one is dead until warm and dead”. In avalanche victims asphyxia is more important than hypothermia. In case of a higher-grade hypothermia, especially in combination with cardiac instability, the target hospital should provide the option of invasive rewarming.
