A clinical study has been carried out on 86 child-bearing mothers, continuous lumbar peridural block being employed, in the light of personal experience, to induce analgesia during labour. The results were positive on the whole as regards duration and the algogenous intensity measured during the dilatation phase and during expulsion.
Cardiac contusion is a fairly frequent clinical event in closed chest traumas. The diagnostic problems it involves influence prognosis in these patients and, in effect, prevention, speedy recognition and early treatment of the complications of cardiac contusion are essential for therapy. Here the incidence of cardiac contusion in a group of patients with closed chest trauma is analysed and the clinical, diagnostic and therapeutic aspects are examined.
Following a short introduction on the stress action of anaesthetics, the effects of anaesthesia with CT 1341 (Althesin) on cortico-adrenal function was investigated, with an evaluation of cortisone plasma concentration. The results obtained in 10 patients point to an increase in plasma cortisone after 30 and 150 minutes of anaesthesia. The discussion hypothesizes the possible influences of the anaesthetic on the hypophyseal-adrenal axis.
A study of the concentration of unconjugated plasma cortisol in nine patients with acute myocardial infarction has been made. The effectiveness of monitoring this factor in assessment of the clinical course and establishing early treatment in this condition is also reported.
In view of disagreements about changes in plasma cortisol, during and after open-heart surgery, a group of patients was studied with both unconjugated plasma cortisol, and anaesthetic, surgical and pharmacological factors that could interfere with the response, being analysed.
A brief account of the stress action of anaesthetic drugs is followed by the description of an evaluation of plasma cortisol concentration in an enquiry into the effects of peridural anaesthesia with bupivacaine.
