OBJECTIVE. The authors assessed an efficacy of correction of visceral blood flow and oxygen-carrying function of portal blood in patients with diffuse purulent peritonitis. The intraportal infusion therapy was applied using ozone-saturated solutions. MATERIAL AND METHODS. There were investigated the dynamics of index changes in blood flow of the portal vein, common hepatic artery, superior mesenteric artery and main parameters of oxygenation of system and portal blood. RESULTS. There was found that the application of intraportal infusion therapy facilitated to hepatic and mesenteric blood flow, oxygen-carrying function of portal blood and liver oxygenation. The method helped to restore liver function and eliminated enteral disfunction and it decreased severity of patients’ state that allowed doctors to improve treatment outcomes. CONCLUSIONS. The intraportal infusion therapy using ozone-saturated solutions is an important part of treatment management in severe forms of purulent peritonitis.

The purpose of this study was to determine the effects of nicotine on intestinal blood flow and oxygen consumption. The intravenous infusion of nicotine at doses corresponding to those experienced by smokers produced a transient increase in systemic arterial blood pressure and mesenteric blood flow. Subsequently a steady-state response developed that consisted of a reduction in mesenteric blood flow due to both a decrease in blood pressure and an increase in intestinal vascular resistance. This increase in resistance was probably due to increased levels of circulating catecholamines. The intra-arterial infusion of nicotine into the intestinal circulation at doses experienced by the average smoker had no effect on either intestinal blood flow or oxygen consumption. Similarly, under in vitro conditions nicotine had no direct effect on intestinal vascular smooth muscle tension. Thus, nicotine appears to reduce intestinal blood flow indirectly as a result of its systemic effects.

ABSTRACT: Pulsed Doppler ultrasound was used to evaluate portal blood flow, portal velocity and portal congestion index in 24 healthy sheep divided into groups (lambs, yearlings and ewes), according to age. Measurements were performed at the 11th right intercostal space using ideal insonation angle and uniform insonation method. Mean values obtained in each group were compared with one-way ANOVA, followed by Tukey post-hoc test. Portal velocity and portal blood flow were statistically similar between the groups (P>0.05). Mean portal velocity were 17.75; 17.13 and 16.75; while mean portal blood flow were 26.65; 31.04 and 24.32 for lambs, yearlings and ewes, respectively. Portal congestion index was statistically distinct between the groups and values for lambs, yearlings and ewes were 0.009; 0.058 and 0.09, respectively (P<0.01). Statistical differences were observed in portal vein diameter, portal vein area and portal congestion index between the groups, presumably due to influence of weight and not to age.
