[Parenteral nutrition. Technique of long term central venous catheterization (author's transl)].

The authors compare two techniques of deep venous catheterization for long term total parenteral nutrition. From December 1, 1973 to April 30, 1974, 31 polyethylene catheters were placed by direct transcutaneous puncture of the subclavian or internal jugular vein in 18 patients. From Mayl, 1974 to March 30, 1975, 35 silicone rubber catheters were surgically placed by cutdown of the basilic vein, in 32 patients. The surgical technique has important advantages such as a safe technique, diminished local and generalized complications and the possibility of intermittent perfusion. Therefore the authors recommend the latter surgical technique for parenteral nutrition lasting 1 to 8 weeks.
