Hypovolaemic shock with oedema due to increased capillary permeability.

A case of severe hypovolaemic shock related to idiopathic oedema was observed in a 37 year old woman. Large plasma volume expansion (nearly 12 1 over 9 hours) did not change the clinical status. Haemodynamic studies showed low cardiac index (1.

[Evaluation of the contractile reserve of the myocardium by post-extrasystolic potentiation in aortic insufficiency].

Calculations were made of the indices of ventricular performance during the ejectional phase in 10 patients with a normal left ventricle and in 24 patients with aortic aneurysm, both under basal conditions and in the presence of extrasystoles produced incidentally during left biplanar cineventriculography. The fact that these indices were constantly raised implies the presence of post-extrasystole potentiation associated with an increase in contractility without significant changes in load. This technique, which provides a dynamic study of the behavior of the left ventricle in aortic incompetence allows us to assess the contractile reserve, and thus to give a more accurate prediction of the potential for recovery after operation.

[Comparative study of the effects of dobutamine and dopamine in septic shock].

This work aims at the evaluation of the effects of dobutamine in the effects of dobutamine in the treatment of septic shock and to compare them to the effects of dopamine used in the same conditions. Eleven patients presenting with both a state of septic shock and confirmed cardiac insufficiency were submitted to the protocol. The dosage was determined by the clinical results : 6.

[Results of a hemodynamic study of valve diseases surgically treated with prosthesis].

The haemodynamic status after valve replacement surgery and the preoperative haemodynamic parameters have been studied for their predictive value in a series of 217 patients who have had aortic, mitral or mitro-aortic valve replacements; all cases had a preoperative catheterisation, and 132 had a postoperative catheterisation at an average of 15 months postoperative. The following conclusions have been drawn from the study: 1. The operation (which consisted of replacement with a Starr valve with Silastein ball-valve in 8 cases out of 10) resulted in a substantial, and statistically significant, improvement in the minor circulation pressures and in the cardiac index.
