RESUMO

Between January 1980 and May 1990 17 patients underwent surgery for prosthetic valve endocarditis at Cardiosurgical Department of Bologna University. Ten patients were female and seven male, the average age was 33 years (range 19 to 67 years). The interval from valve replacement to onset of symptoms of prosthetic valve endocarditis was less than 2 months in 5 patients and longer than 2 months in 12 patients. Sixteen of 17 infected prostheses were mechanical and one biological. All patients were surgically treated and the infected prostheses replaced with new valve prostheses. The hospital mortality rate for early prosthetic valve endocarditis was 60%, for late endocarditis was 16.5%, global hospital mortality was 29.4%.

RESUMO

High incidence of postoperative arterial hypertension, confined to the first 24-48 hours and independent of the preoperative pressure situation, has been noted in patients following vascular surgery. The phenomenon is more frequent in patients whose angiosclerotic symptomatology goes back more than 2 years, and in those in whom preoperative investigation showed high daily variability in measured values, always however within non-pathological limits. Analysis of possible intraoperative pathogenetic factors in postoperative hypertension reveals a significant relationship between this phenomenon and inhalatory anesthesia, particularly with fluothane and curarization with D-tubocurarine. Co-responsibility of respiratory factors, particularly hypercapnia, has never been documented by haemogasanalysis. As for the pathogenetic mechanisms responsible for this type of hypertension, measurement of urinary catecholamines has revealed a close relationship between the two phenomena. The same investigation, extended to a wider group of patients, showed that by comparison with patients submitted to balanced anaesthesia, those who had received inhalatory anaesthesia with fluothane show, with much greater frequency, increased urinary elimination of catecholamines during the operation and for 24-48 hours afterwards. Catecholaminic hyperincretion, more frequent in fluothane anaesthesia, thus seems to be an important pathogenetic factor in these hypertensive manifestations in which the angiosclerotic medium presumably acts as an amplifier.
