[External heart compression with the heel (author's transl)].

External heart compression during cardiopulmonary resuscitation is an usual method. As an alternative to the arm-hand method the leg-heel method is proposed. Both methods were tested with a group of laymen and paramedical personnel at the Recording Resusci-Anne manequin. Criteria of evaluation were frequency, point, intensity and direction of heart pressure. 64 per cent of all test persons found the method of heel-compression to be of no value of the basis of personal experience. They showed early fatigue and complained of leg pain. The incidence of failure for both methods was comparable. Frequency and intensity of pressure showed no differences. The most important disadvantage appeared to be the lack of discharge of the sternum at the end of the phase of compression. Experience has shown that difficulties may arise from teaching several methods. Therefore the teaching of laymen should be restricted to one method only, usable universally. The restrictions of the leg-heel method are listed.

[Blood coagulation disorders in polytraumatized patients].

The lapse of coagulation disorders in polytraumatized patients is regarded as a substantial part of complications in the course of traumatic-hemorrhagic shock. In 71 polytraumatized patients blood-clotting tests were performed and showed that changes may already occur at a very early stage of the shock. The extent of these changes is closely related to the degree of the injury. It could be demonstrated that prompt shock-treatment and maintenance of adequate circulation as well as administration of low doses of heparin are important for spontaneous recompensation of the hemostatic defect.

[Clinical aspects of massive transfusions].

Clinical aspects of massive transfusion (a minimum of 51 blood/6 hours) were investigated in 30 surgical and urological patients. Main bleeding causes were large tumors, liver surgery, prostatectomy and vascular surgery. Two thirds of the patients died, half of them from irreversible hemorrhagical shock. In secondary causes of death were clotting disturbances, renal failure and infections. About 50% of the transfused patients developed hyperbilirubinemia and hypokalemia. The aim of therapy in massively bleeding patients should be a sufficient continuous substitution of blood volume, heated and filtrated blood, heparinisation and balanced substitution of clotting factors.

[Dynamics of blood coagulation disorders in traumatic-hemorrhagic shock].

Blood clotting tests in 55 polytraumatized patients showed that a lapse in the hemostatic potential may already occur at a very early stage of the traumatic-hemorrhagic shock. The extent of these changes which are complex in their pathogenesis, is closely related to the degree of injury. Coagulation-analysis control of the development shows clearly that shock treatment and maintenance of adequate circulation, starting at the earliest possible moment at the scene of the accident, are important for spontaneous recompensation of the hemostatic defect.

[The influence of blood transfusions on changes of the coagulation in polytraumatized patients (author's transl)].

In 55 polytraumatized patients blood clotting tests were performed and analyzed in relation to the severity of the injuries and traumatic-hemorrhagic shock and the amount of homologus blood transfused. The degree of the changes of the clotting parameters was found to depend mainly on the severity of shock. The amount of transfused blood had of no influence. The results indicate the importance of an early i.v. fluid therapy corresponding to the demand of volume and the replacement of blood lost by haemorrhage.

[The ECG in emergency patients and its therapeutic consequences (author's transl)].

The increase in internal emergencies compels the doctor on emergency duty to differentiate. For the primary diagnosis, in addition to palpation of the pulse and the patient's utterances of pain, the leads of an ECG are available in the emergency ambulance. Therefore tachycardias, bradycardias and arrhythmias can be differentiated. The question of the therapeutic consequences in the individual case according to the classification of these different forms of rhythmic distrubances by the doctor first treating the case are discussed. General guiding principles for treatment are pointed out.
