[Hemodynamic and oxygen transport effects of dobutamine in critically ill patients].

The study evaluates the cardiocirculatory and oxymetric effects of dobutamine infusion in doses between 5 and 15 g/kg/min for a period of 48 hours in 18 critical patients of whom 9 with a low cardiac index (mean 2.1) and 9 with a normal or increased cardiac index (mean 3.3).

[Presentation of a case of severe abdominal infection caused by anaerobic bacteria].

The problem of surgical infections is discussed, special attention being paid to the commonest bacterial agents, particularly those extremely serious forms induced by gram negative and anaerobic microorganisms. After an introduction regarding isolation methods and respective therapeutic programmes, attention is turned to the case of a young woman observed after an operation for perforated appendicular abscess later complicated by stercoraceous peritonitis. After initial antibiotic treatment, which was without effect, an association comprising Clindamycin, penicillin and gentamycin was employed.

[Value and limitations of determination of total serum CPK in patients with complicated myocardial infarct. Case statistics for 1974-1977].

The Authors, starting from a casuistic formed over four years at the "Servizio di Anestesia e Rianimazione dell'Ospedale Fatebenefrateli di Milano" where there is no coronaric unit and that gathers patients with complicated myocardial infarction, considered the developing of the enzyme CPK in the various clinical phases of these patients. On the basis of these data, we confirm with other Authors have already observed: that is, the value of the total serum CPK isn't a prognostic index fit in the evaluation of the clinical developing of the person with myocardial infarction, especially if complicated.

[Experience in prophylactic peroperative cardiac electrostimulation (author's transl)].

The Authors refer on about 35 cases of prophylactic peroperative cardiac electrostimulation on about 50,500 cases undergoing surgical procedures during seven years. The indications were: bifascicular block, complete left bundle branch block, primitive sinusal bradycardia, surgical correction of carotid synus syndrome, atrial fibrillation with spontaneous low ventricular rate, neurosurgical treatment of cranial trauma by suspected MAS syndrome, surgical implantation of epicardial electrodes. It is enphasized the necessity to continue with prophylactic peroperative cardiac stimulation in all these cases, except for bifascicular blocks for which one has to decide case by case according to the clinical history and ECG findings.
