CLINICO-EXPERIMENTAL ANALYSIS OF BACKGROUNDS OF THE SEVERE SURGICAL INFECTIONS

The purpose of this study was to analyse the clinical courses of 410 patients of severe surgical infections (primary 251, postoperative 159) during recent 5 years and to evaluate the important background factors which make these patients serious. As a result, the following patients such as, (1) who have refractory primary infections, for example malignant lymphoma, severe pancreatitis etc. (2) whose infectious foci were uncontrolled. (3) who had finally complicated a septic MOF or DIC, seemed to be especially critical even through recent advanced surgical therapy.
To improve these severe conditions, we believe to need a renewed approach like so called “multi-disciplinary therapy”, additionally with both conventional antibiotics administration and drainage for infectious foci. Several methods such as. (1) rational nutrition management using indiret calorimetry. (2) plasma exchange for removing toxic substances such as bacterial toxins, chemical mediators etc, from ciruclating blood. (3) pharmacological block of these toxic substances, were shown. In terms of the harmful chemical mediators, we supposed that both PAF (platelet activating factor) and oxygen free radical were extremely important in septic conditions from previous clinico-experimental studies. Therefore the effects of those pharmacological blockers such as PAF antagonists, SOD, protease inhibitor in experimental endotoxin shock were discussed in detail.
