Cannulation of the proximal aorta during long-term membrane lung perfusion.

Prolonged extracorporeal oxygenator support for acute respiratory failure is a clinical reality. Recent experience with 4 patients has demonstrated an advantage in delivery of saturated blood to the root of the aorta during venoarterial (VA) bypass. We have been able to perfuse the heart and bilateral cerebral hemispheres by advancing the tip of a large perfusion cannula to the aortic root from the common femoral artery.

Effect of increased vascular pressure on lung fluid balance in unanesthetized sheep.

In 20 unanesthetized sheep, we measured lung lymph flow and lymph and plasma protein concentrations during steady-state base-line conditions and during steady-state elevations of pulmonary microvascular hydrostatic pressure (range 3 to 23 cm H2O). In every sheep there was a base-line lung lymph flow (average 5.7 +/- 2.

[1st experience with the use of a flexible fiber endoscope].

X-ray examinations as a basic method of recognizing pathological processes in the descending segments of the intestinal tract do not always make it possible to ascertain the nature of the affection. An effective diagnostic method is endoscopy that can be implemented with the help of the Soviet-made flexible fibre endoscope, model CBO-1. The device is reliable in operation, easy and convenient to handle and allows it to examine not only the sigmoid flexure, but the descending segment of the large intestine as well.
