RESUMEN
UNLABELLED: Colloid solutions can give severe anaphylactic accidents. We are reporting two cases from our department. FIRST CASE: a sixty eight years old man perfused with Plasmion solution (Gelatin plasma substitute) before spinal anesthesia, presented sudden hypotension and diffuse skin rush. Second case: a twelve years old girl, receiving a Plasmion solution to correct a hypovolemic shock in I.C.U, presented a severe bronchospasm and a worsening of the hypotension. These accidents are explained by immunologic reactions or by direct histamine release. Their incidence is between 0.01 and 0.8 percent depending on the used solution. They are prevented by an antihistaminic premedication for the gelatin plasma substitutes and by an haptenic inhibition for Dextran (polysaccharide plasma substitutes). The new colloid solutions, based on hydroxyethylstarch, seems to give much less allergic reactions.

We are presenting our experience with 70 deep venous catheters for long term chemotherapy. Despite the well known complications of these procedures, the implantation of subcutaneous injection sites has facilitated the management and brought much more comfort to cancer patients. Strict measures of survey and meticulous nursing care are essential for optimal use of the injection sites.
