In patients with disturbed gas-exchange (e.g. COPD) intratracheal oxygen insufflation (ITO2) improves oxygenation and reduces the minute ventilation. We use a bronchoscopic technique of intratracheal catheter placement in unintubated patients. In a patient with a pink-puffer emphysema after endoscopical insertion of the catheter ITO2 induced a "continuous flow apnoeic ventilation" (CFAV). ⋯ In a patient with an acute on chronic respiratory failure due to end-stage emphysema ITO2 induced CFAV and stabilized the clinical status. Especially in patients with end-stage emphysema, who are likely to be difficult to be weaned from the respirator ITO2 may be a feasible technique in order to bridge an emergency situation.

Until now there is no conclusion about a distinguished long-term O2 therapy in patients using IPPV. ⋯ 1. A distinguished long-term O2 therapy with testing the need in rest, under IPPV and in activity is convenient. 2. Regular controls are necessary because of the individual changings.

The most important complications of deep vein thrombosis are pulmonary embolism and postthrombotic syndrome. While the medicine of lethal pulmonary embolism is reduced to less than 2% by conventional anticoagulation, fibrinolytic therapy aims at a reduction of the greater than 50% incidence of postthrombotic syndrome. The optimal therapeutic regimen concerning risks and effect has not been established yet. ⋯ UHSK can be regarded the standard concerning success rate in deep vein thromboses. DATA involving locoregional therapy with rt-PA are inconsistent and worse, but bleeding complications might be less frequent. Large prospective studies evaluating the impact on incidence and severity of the postthrombotic syndromes, which involve a controlled application of compression therapy are needed.

In order to exclude hemorrhagic diathesis, e.g. before diagnostic measures carrying the risk of bleeding or in preoperative situations, a graded screening is advisable. ⋯ During the first stage, besides the anamnesis, clinical examination and classification of relevant concomitant diseases (e.g. liver cirrhosis or renal insufficiency), basic laboratory examinations such as prothrombin time, activated partial thromboplastin time (aPTT) and platelet count must be carried out. Should all these measures produce no noteworthy results, no further examinations are necessary. However, in the case of test results within normal limits accompanied by an unsatisfactory anamnesis and/or conspicuous clinical findings, the second stage should include examination of bleeding time according to Mielke to exclude a relevant platelet dysfunction. Should this be inconspicuous a third stage should follow in which successive implementation is made of fibrinogen according to Clauss, the Rumpel-Leede test (to exclude heightened capillary fragility), factor XIII and alpha 2-antiplasmin. The methodical snares of the parameters mentioned will be explained in full.

Antiphospholipid antibodies comprise a family of auto-antibodies mainly characterized by the presence of the lupus anticoagulant (LA) and anticardiolipin antibodies (ACA). ⋯ Patients with thrombosis associated with APA should receive long-term anticoagulation therapy, whereas treatment of asymptomatic patients seems to be not indicated, because only approximately 10% of patients with APA may develop thrombotic complications. In patients with PAPS there is no evidence that the prophylactic administration of immunosuppressive drugs will prevent thromboembolic events.
