[Experience with intra-aortic balloon pumping preventively used in patients with a low left ventricular ejection fraction, operated on under extracorporeal circulation].

One hundred and fifty-six patients with coronary heart disease and a low (less than 30%) left ventricular ejection fraction (EF), operated on under extracorporeal circulation and preventive intra-aortic balloon pumping (IABP) were examined. The latter was found to promote the maintenance of stable hemodynamic parameters during and after surgery. Postoperative acute heart failure developed in 101 (64.

[Treatment of the patients with complications of colon malignant tumors].

Results of treatment of 150 patients with colorectal cancer complicated with obturation intestinal obstruction are analyzed. Rational health care organization has permitted to increase operability and respectability of tumor to 96 and 87% accordingly compared with 73 and 57.5% at control group.

[Thyroid hormones during the correction of acquired mitral defects under perfusion-free hypothermia].

Total triiodothyronine and thyroxine were measured in the blood plasma during different stages of surgery and after it in 26 patients operated on the open heart under conditions of hypothermia without perfusion. Cooling without perfusion did not appreciably affect the levels of thyroid hormones. Only their ratio was evidently changed at cooling below 30 degrees C with the predominant content of thyroxine.
