Evaluation of preoperative blood tests for predicting deep vein thrombosis after total hip replacement.

Determinations of the total calcium content and aggregability of the platelets as well as tests of coagulation and fibrinolysis were carried out on 93 patients before undergoing total hip replacement. All patients received low dose heparin, solely or combined with dihydroergotamine. Twenty-six patients developed deep vein thrombosis (DVT) detected by the labelled fibrinogen uptake test and confirmed by ascending phlebography. Only a few tests, among them the total calcium content of platelets, showed a statistical difference between the patients who subsequently developed DVT and those who did not. Combination of several tests by a multivariate statistical analysis programme proved to have more predictive value than the analysis of single tests.

[Comparison of the values of automatic ECG analysis according to the Smith and the Pipberger diagnostic programs by means of a serial study in a large industry].

It could be shown that an ECG-screening could be integrated into the routine work of a factory outpatient department. As a result of the automatical analysis of the ECG we got an exact knowledge of the efficiency of Smith's and Pipberger's diagnostic programmes. The suitability of the two programmes for screening examinations resulted from the 91% and 97% certain separation of normal and pathological findings and the small proportion of falsely negative results (Smith, Pipberger). Concerning the exact differentiation of pathological ECG the frequency of recognition of Pipberger's programme still surpassed that one of Smith's programme. However, the two programmes show a diagnostic security which lies above the visual diagnosing. The establishment of findings performed off line per week ascertained a rapid disposal of results. In comparison to former examinations newly detected cases could be established only in a small percentage. The importance for health polities of such examinations results from the necessity of the prophylaxis of cardio-vascular diseases, the numbers of morbidity and mortality of which are permanently increasing.

[Experience in the use of Smith's ECG evaluation program].

After the experiences with the use of the programme of Pipberger concerning the automatised ECG-analysis in clinic, outpatient department and factory public health, which were made at the Medical Academy Erfurt during the last years, at this time comparative examinations with the ECG-analysis programme of Smith were performed. The intake of data (3 orthogonal leads) is done by means of a data establishing unit developed by us. For the analog-digital-changing, the pretreatment of data and the transmission of the ECG-data on the digital magnet tape a process-calculator TPA-i is used. The analysis is performed by the computer Robotron 21. The evaluation of the results shows that, when a great number of patients is examined, normal curves are correctly estimated at 100%. The recognition rate of pathological curves has with 79.5% about the same size as the visual judgment. The deficiencies of the diagnostic programme of Smith must be essentially found in the relatively high proportion of falsely negative findings, the insufficient differentiation of the changes of the chamber variation, in the sometimes incorrect formation, why the classification of the curves in individual groups was performed. On account of the certain centage of falsely negative ones the programme is well recognition of normal findings and the tolerable pernotion of the diagnosis and the sometimes lacking insuited for screening examinations.
