[Cardiopulmonary insufficiency after lungresections (author's transl)]. / Uber die kardiopulmonale Insuffizienz nach Lungenresektion und ihre Vermeidung.

Among 1248 patients with lung resections (1964 to 1974) 76 developed cardiorespiratory failure and had to be managed by PEEP respirator care. Only 18 (23%) survived. These cases were thoroughly analyzed, and a formula was derived. By using ventilatory function, blood gas values, age, ECG it permits to evaluate the probability of cardiorespiratory failure in case of pulmectomy or lobectomy respectively. This evaluation was found to be correct in 99% of the cases.

[Preoperative determination of the probability of a pulmocardiac insufficiency after resection of the lung]. / Zur präoperativen Ermittlung der Wahrscheinlichkeit einer pulmokardialen Insuffizienz nach Lungenresektion

Pneumonectomy is endangered above all by pulmocardial insufficiency. Its probability can be calculated in advance by a simple formula and a nomogram. With the help of a special mathematical method the most important functional parameters have been investigated and the formula and nomogram have been derived. The safety of the prediction comes up to the demands of biostatistical significance.

[Reoperation in bronchial carcinoma (author's transl)]. / 25. Reinterventionen beim Bronchialcarcinom

After lung resections in bronchial carcinoma, reoperation for recurrences, metastases, or secondary primary tumors is rarely possible. The possibility depneds on the extent of the primary resection, the physiological state of the patient, and the spread of the primary or secondary tumor. From 1950 to 1975 1628 lung resections were performed in Düsseldorf, with reoperation in 26 cases (1.6%). n Bremen (1964-1974) 915 lung resections were performed, with 20 reoperations (2.2%). Survival times recorded in Bremen and Düsseldorf and in the literature justify reoperation in individual cases.

Diagnostical and therapeutical problems of mediastinal tumors are reported, and their management is described. Lethality was 9% (causes related to the operation, including final stages of advanced tumors).
