[Acute respiratory distress syndrome of the adult (ARDS) and artificial respiration--results in surgical intensive care patients].

A prospective clinical trial was performed in an operative intensive care unit to examine the incidence and outcome of patients with adult respiratory distress syndrome (ARDS) and the outcome of intensive care patients on mechanical ventilation and the incidence of barotrauma and pulmonary infection. 161 mechanically ventilated patients showed an overall mortality of 19.9%. The mortality rate in the ARDS patients was 11 of 26. Most of these patients with ARDS died from multiorgan failure. Pulmonary infection was the most frequently registrated complication of mechanical ventilation. We conclude from these data that --according to the literature the outcome of surgical ICU patients on mechanical ventilation with and without ARDS is more favourable than that of medical ICU patients; --the interpretation of therapeutic results and of epidemiological data in ARDS patients is possible only by providing exact and detailed criteria; these should include compliance data; --evaluation of present ARDS therapy by comparison to previous data, even when the same criteria are applied, e.g. ECMO-criteria, may fail as the outcome of conventional therapeutic measurements - mechanical ventilation - may have improved. A controlled randomised trial might be more suitable for evaluation of alternative therapy in ARDS.

[Respiratory problems related to general anesthesia and artificial respiration in the pregnant woman and during childbirth].

General anaesthesia in pregnancy is still responsible for a significant morbidity and mortality. The most common and most serious complications are respiratory secondary to changes induced by pregnancy. These are dominated by hypoxia during difficult intubation and inhalation of gastric contents. Their incidence could be largely reduced by the extensive use of regional local anaesthesia.

[High-frequency artificial respiration. II. Intratracheal high-frequency pressure changes with a rotation-valve catheter].

From the history of ventilatory support, the early studies of Auer und Meltzer only now seem to find a functional explanation. A rotating valve mounted on the tip of an endotracheal tube delivers a widespread gas bolus. The turbulent flow acts as a stirring device on the intrapulmonary gas volume. The method reduces the directional selectivity that typically limits the efficiency of jet ventilation. Systematically changing the rotational frequency between 10 and 80 Hz allows sequential stimulation, compartment by compartment, of the entire lung, which also gives rise to frequency-dependent local air-trapping that sequentially inflates different compartments. Jet ventilation and high-frequency oscillation were compared in dogs with the rotating valve tube by taking blood gas samples from 4-6 intrapulmonary veins: jet ventilation is characterized by preponderant ventilation of lung compartments opposite the lower aperture of the endotracheal tube. High-frequency oscillation induces a frequency dependent repartition of alveolar ventilation. The rotating valve tube definitely contributes to the homogenisation of alveolar ventilation in a manner that is less dependant upon segmental compliance than conventional ventilation.
