[Postoperative ventilation using the iron lung principle. A renaissance of this form of artificial respiration?].

Artificial ventilation using the iron lung as an alternative to endotracheal intubation and respiration may be a useful method in reducing bronchopulmonary infections attributed to postoperative ventilation or resulting during intensive care treatment. The concept of transferring and further developing this "external" respiratory principle to anaesthesiological situations is presented. Four high-risk surgical patients were subjected to post-operative artificial ventilation with the iron lung: the results demonstrated that this method was effective and well tolerated. Another speciality planned for its employment is transplant surgery. Numerous other fields could also be considered. Before the iron lung can be put to use in anaesthesiology certain further developments are required. These developments relate to its practical aspects and more importantly to the additional ventilation possibilities which can be achieved. The future extent of employment of the iron lung in anaesthesiology cannot be predicted at present. In our opinion, however, this form of respiration could prove an adequate method in special situations.

[The behavior of intracranial pressure under spontaneous respiration or artificial respiration in hemorrhagic shock during volume substitution].

Haemorrhagic shock and cranial injury frequently present together in the polytraumatised patient. The effect of different forms of ventilation--spontaneous respiration, controlled normoventilation, and intubation followed by hyperventilation--on the raised intracranial pressure of young pigs given volume replacement subsequent to haemorrhagic shock, was therefore investigated. During volume substitution, the intracranial pressure (initially 30 mmHg) both of those animals breathing spontaneously and of those being ventilated rose significantly (44.6 and 49.2 mmHg respectively). In contrast, intubation and hyperventilation resulted in an initial fall in intracranial pressure to 18.6 mmHg, and a rise to just below initial values (27.4 mmHg) after volume replacement. A similar blood pressure rise was noted in all three groups but arterial PCO2 changes were analogous to those of intracranial pressure. In the presence of both haemorrhagic shock and cranial injury, volume replacement alone is not sufficient treatment, and can in some circumstances be dangerous. Early intubation and controlled hyperventilation course a fall in intracranial pressure secondary to decreasing the PCO2.

[Histomorphologic lung findings in long-term artificial respiration with special reference to extreme continuous artificial respiration using pure oxygen].

The respirator lung is characterized histologically in the first exudative phase by capillary congestion, intra-alveolary edema, hyaline membranes and in most cases by concomitant inflammatory alterations. In the following irreversible phase, fibrous organization processes dominate and show a variable tendency towards pulmonary fibrosis. In 27 cases with long-term artificial respiration from 4 days to 12 weeks, mainly the proliferative alterations were investigated. In 18 cases, the histopathological findings indicated fibrosis of the alveolar septa with disseminated distribution. In 9 cases, focal fibrosis with obliterations of alveoli prevailed. The extent of pathological results in the lungs does not correlate with the duration of artificial respiration. In cases of artificial respiration with pure oxygen, there is a special toxic component, which is illustrated by a young woman with polytraumatism who was administered artificial respiration for 5 weeks with pure oxygen. She died from respiratory insufficiency with severe pulmonary fibrosis. As different pathogenetic factors may cause irreversible pulmonary fibrosis, histomorphological classification is difficult later and, moreover, forensic problems result.
