The Caval Catheter by Professor Dr. Caius Burri, Professor Dr. Friedrich Wilhelm

By Professor Dr. Caius Burri, Professor Dr. Friedrich Wilhelm Ahnefeld (auth.)

The program of the caval catheter in emergency medication and in depth care has this present day turn into regimen. mostly, even in serious surprise this direction of entry to the cardiovascular method comes in order to use lifestyles saving quantity substitution. It additionally allows longterm infusions in glossy extensive care, fairly non-stop management of high-osmolarity ideas in par­ enteral meals. In either fields it represents some of the most vital diagnostic parameters of circulatory issues, enabl­ ing the registration of critical venous strain. Its indisputable merits are counterbalanced via the hazards inherent in all invasive equipment. on the grounds that adequate adventure and detailed sta­ tistics are actually at our disposal, the time has come for a provisional survey. whereas many years in the past it used to be thought of essential to propagate the primary venous entry for you to boost new healing and diagnostic equipment, it's now essential to recon­ sider and reformulate symptoms for its use. during this job it's necessary to weigh the anticipated merits opposed to the prospective problems in every case of catheter program. Cri­ tical scrutiny needs to contain review of innovations, techniques, and eventually catheter fabrics; this paper provides the result of this kind of survey. The medical professional is hereby given the potential of being thoroughly proficient of comparing the validity of his regular strategies. VIm, April 1977 C. BURRI F. W.

Phthalates have since been demonstrated in various American rivers. Early measurements in maritime organisms have shown a rise in these substances to 350-3900 times the normal level in their living space (BAR, 24). Acute signs of intoxication after inadvertent ingestion of up to 10 ml phthalic ester were not observed but there are increasing indications of an insidious toxicity of these substances, especially with parenteral use, in the form of disturbances of antibody production, increased vascular permeability, injury to vascular endothelium with induction of thrombosis and, still doubtfully, hepatitis-like liver function disturbance (NEEGARD, 354).

If the injury is situated outside the thoracic region, as in the cases of BURRI (88) and GOYANES (197), a local hematoma develops or, if infusions are administered through the catheter, some tissue change due to the fluid. If the perforation occurs in the region of the subclavian, brachiocephalic, or caval vein, the catheter tip enters the pleural cavity or the mediastinum. In these cases blood transfusion leads to an iatrogenic hemothorax, infusion solution to a hydrothorax (Fig. 31). Such cases have also been described by ASHRAF (13), SCHWEIKERT (423), DEUBZNER (124), and MAHAFFEY (323).

The shorter approach to the superior caval vein is therefore on the right. The right angulus venosus receives the right lymphatic trunk, collecting the lymph from the axillary nodes, clavicular nodes, and thoracic cavity, while the left angulus venosus receives in addition the Fig. 19. Topography of subclavian and anonymous vein on the right side 27 lymph from the lower extremities via the thoracic duct (Fig. 19). Two topographic facts especially favorable for catheterization of the superior caval vein should be emphasized (LAND, 294, 295): In the supraclavicular fossa the subclavian vein parts from the closely parallel running artery which turns in a dorsal direction and the subclavian and brachiocephalic (anonymous) veins are connected by connective tissue with the fasciae of the subclavian and ventral scalenus muscle and the medial fascia of the neck in such a way that their lumina are wide open even in marked hypovolemia and the vessels can hardly be missed by the puncture needle.
