[Surgical shock. Acute hypocatecholaminemia and therapeutic indications of an adrenocortical vasopressor sympathicolytic drug mixture. Clinical studies and experimental research].

In cases with postoperative shock and collapse a constant fall in the concentration of serum cathecholamines was noted. Thus adrenalin was reduced by 77%, noradrenalin by 86.5%, in direct proportion with the fall in the blood pressure, of the pulse amplitude and with the slowing-down (or the arrest) of the microcirculation. The reduction of serum cathecholamines also coincided with a decrease in the amount of buffer bases and of the diuresis. The adrenocortical vasopresor sympathicolithic mixture is indicated in the prolonged arterial hypotension following failure of therapy aimed at filling of the vascular bed associated with the administration of sympathicolytic drugs.

Variations of catecholamines in mixed shock. Therapeutic implications. Experimental and clinical investigations.

The variations of catecholamines, cortisol and aldosterone in mixed shock (traumatic, hemorrhagic and septic) were studied experimentally and clinically. In the stage of collapse adrenaline decreased by 81.4% and noradrenaline by 62.6% as compared with the preoperative values. These decreases were found to be directly proportional to the decrease of arterial blood pressure, pulse amplitude and diuresis as well as to the slowing down or even stop of microcirculation. The value of plasma cortisol increased in the stage of collapse by 98.3% and that of aldosterone by 66.27% as compared with the preoperative values. Treatment with a pharmacodynamic sympatheticolytic-vasopressor-adrenocortical mixture is recommanded when the blood pressure remains below 50--60 mm Hg for 1--2 hrs and when the treatment for the correction of hypovolemia with fluids and sympatheticolytics has failed. Clinically, this treatment gave good results in 34 of the 58 cases studied (58.6%).

[Treatment of duodenal stress ulcer by means of chemical sclerosis of the gastric mucosa induced with a 60 percent glucose solution (results after 1--5 years)].

Sclerosing of the gastric mucosa with a 60% fresh sterile solution of glucose was applied in 60 selected patients with chronic conflictual duodenal ulcers, hyperacidic gastritis by vagal neurogenic hyper-reactivity, associated with ischaemic gastropathy developed on an sympathico-adrenergic background. The immediate operatory results were good. The late results (between 1 and 5 years) were as follows: the clinical, radiological and metabolic results were good in 57 patients. Gastric chemical analysis, the values of the hourly basal output remained high in 16,6% of the patients, and those of acidity stimulated by histamine administration remained high in 13,3% of the patients. No peptic recidive was recorded. Unsatisfactory late results were noted in 3 patients (of which forced indication of the method in one patient and non-association of drainage in two patients).

[Polyps; rectocolic polyposis. Etiopathogenic and anatomoclinical data. Results].

The authors statistic concerns 370 interventions for adenomatous polyps and rectocolic polyposis (105 segmental exereses, 32 total or sub-total rectocolectomies, 233 direct, endo-anal or laparocolotomy electroresections). The necessity is stressed of the early detection of isolated, or of multiple polyps, or of potentially malignant polyposis, either genetically inherited or acquired, and on their radical extirpation from the beginning, an attitude that improved late oncologic prognosis (98% survivals after 5 years).
