[Knotting of stomach and endotracheal tubes].

After transnasal placement of a tracheal and a gastric tube, the latter did not function properly. Several attempts to remove the gastric tube were unsuccessful, but this could not be explained on several laryngoscopic inspections. The palpating finger finally found a knot of tracheal and stomach tubes high in the epipharynx. This incident underlines the importance of faultless functioning of tracheal and stomach tubes, especially in patients with intended intermaxillary fixation.

Unidirectional 8-MHz continuous wave Doppler equipment can facilitate catheterization of the internal jugular vein.

In a prospective study, 8-MHz unidirectional, continuous wave Doppler equipment was shown to improve the success rate of internal jugular vein catheterization. In the first series of 100 patients, punctures were randomly divided into two groups, via the anterior or posterior route, representing the standard technique. The second series of 50 patients underwent punctures guided by the Doppler technique. The Doppler route was successful in 48 test punctures with 47 catheter placements. Via the anterior route, 14 of 50 test punctures were positive, with 11 catheter placements; for the posterior route, test punctures were positive in 25 of 50 cases, with 18 catheter placements. With the Doppler technique, it should be possible to increase the rate of successful catheterization of the internal jugular vein while reducing complications.

[Doppler ultrasound in anesthesia and intensive care medicine].

The ultrasound Doppler technique is a non-invasive method for the evaluation of arterial and venous blood flow. It can be useful in anaesthesia and in intensive medicine for different purposes, e.g. for more exact blood pressure determination in difficult cases, in cases of blood supply disorders or as a helpful guide for the puncture of arterial and venous vessels. This technique has also been used successfully as a screening method of cerebral death, for the evaluation of flow rates during arterio-venous hemofiltration and for the investigation of the effects of peridural anaesthesia on peripheral resistance.

[Ultrasound Doppler sonography: a simple method for the improvement of internal jugular vein catheterization].

Although many different approaches have been recommended for catheterization of the internal jugular vein, sometimes difficulties and serious complications may occur. The Ultrasound-Doppler-technique is a simple and non-invasive method for localizing and differentiating arterial and venous vessels, e.g. carotid artery and internal jugular vein. A method for puncture of the internal jugular vein with the help of the Ultrasound-technique will be described. In our investigation of 150 punctures this method proved to be superior to approaches recommended up until now.

[Successful therapy of consumption coagulopathy in EPH gestosis with multiple organ failure].

A 23 year old primipara with EPH gestosis after caesarean section suffered massive disseminated intravascular coagulation resulting in anuria, respiratory failure, gastrointestinal bleeding and disturbance of liver function. By treatment with antithrombin-III concentrates, fresh blood and fresh frozen plasma we were able to normalise coagulation disorders and to restore organ functions. Causes and therapeutical management of these diseases are discussed.
