[Place of anti-inflammatory agents in the prevention of deep phlebitis].
The inflammatory reaction includes, after an initial tissue lesion, a catabolic phase with proteolysis, an exudative reaction phase, and finally an anabolic phase with the formation of an inflammatory granuloma. The reaction should be considered, however, as an initial inflammation, rapid and limited to the affected tissues, and a secondary inflammation induced at a distance by a humoral mechanism with the appearance of pathological globulins. Only certain anti-inflammatory agents act at these two levels : steroids and non-steroids. Corticosteroids can be used effectively in small doses. Courses of salicylates are difficult to manage and are not standardized. Fenamates and indometacine lead to psychiatric disorders. The only useful drugs are phenylbutazone and hydroxyphenylbutazone. These two drugs can be used alone, or in combination, or eventually being superseded by anti-coagulants. As they are derived from pyrazolidine, they are above all preventive. Their absorption in the digestive tract is rapid and almost complete ; the maximum plasma concentration occurs 2-4 h. after injection. Delayed accidents occur 7-15 days after the last dose. Suppotanderil and suppophenylbutazone are used at the dose of 250ml, 2 or 3 times a day. They may be combined with AVK depending on the clinical signs and the prothrombin and Howell's time. These drugs are contraindicated in patients with ulcers, with haematological diseases, and with severe cirrhosis. They should always be replaced straight away by anti-coagulants in patients with valve prostheses or with severe rhythm disorders.
