REGIONAL DIFFERENCES OF THE CENTRAL VENOUS PRESSURE AT AN EXPERIMENTAL INTRA-ABDOMINAL HYPERTENSION
Goal of the research is estimation of value of the central venous pressure in the superior and inferior cava vein at experimental intra-abdominal hypertension. The study was conducted on 10 piglets. Intra-abdominal hypertension modeling was spent by means of filling by a physiological solution of the cylinder established in an abdominal cavity. Growth of the central venous pressure in the inferior cava vein authentically reflected increase in intra-abdominal pressure. At increase in intra-abdominal pressure to 20 mm hg the central venous pressure in the superior cava vein practically didn’t change. At the further increase in intra-abdominal pressure to 25 mm hg there was a sharp lifting of the central venous pressure in the superior cava vein. At intra-abdominal pressure of 30 mm hg and above level of the central venous pressure in the superior cava vein came nearer to zero. Thus, the complex analysis of value of the central venous pressure in superior and inferior cava vein can be used as an estimation of a formed syndrome of an intra-abdominal hypertension.
