[Intraoperative hemodynamics in the recipients of kidney allografts from living related donors].

Electromagnetic flowmetry was performed in 53 recipients of kidneys from related donors to investigate intraoperative hemodynamics and its relationships with such factors as the degree of histocompatibility between the donor and recipient, of blood relationship, renal laterality. The real total blood flow was compared to proper flow according to Inke formula. The result of this comparison gave evidence for angiospasm or vasodilation.

[Anesthesia and brain protection in reconstructive surgery of brachiocephalic arteries].

Application of a shunt is not the principal factor preventing brain blood flow disorders in reconstructive surgery on the carotid arteries in conditions of general anesthesia with anesthetics of an antihypoxic action, reducing oxygen consumption by the brain, combined with adequate compensation of the circulating blood volume, moderate hemodilution, elevation of the systemic arterial pressure and heparin. The authors claim that even in patients with bilateral stenosis of the carotid arteries or with occlusion of one of these arteries surgery may be carried out without shunts or craniocerebral hypothermia. Still, they do not deny a bypass application, particularly by the surgeons who always use it, or in cases with a drastic inhibition of the brain electrical activity, evidenced by EEG, which they consider a sufficiently reliable indicator of the brain blood flow adequacy.

[Endolymphatic pressure in the evaluation of the status of peripheral lymph flow in the extremities].

The functional capacity of the lymph vessels in their various pathological conditions was determined from 78 studies of the endolymphatic pressure in patients with lymphatic edema of the extremities. Four types of pressure curves were determined according to the maintenance of the contractility of the wall of the lymph vessels. It was found that marked hypertension develops in the lymphatic channel in obstruction of lymph drainage from the extremity.
