Aim. To assess the clinical value of continuous monitoring of rheographic parameters in patients with high risk of recurrent gastrointestinal bleeding for early pre-clinical diagnosis of recurrent bleeding. Methods. The study included 50 patients with upper gastrointestinal bleeding aged 50 to 70 years who were admitted having hemorrhagic shock III after endoscopic hemostasis. Continuous integral whole body rheography by «Diamant-M» computer complex was used for systemic circulation assessment.

... Results. Three types of hemodynamic reactions were revealed at integral whole body rheography: hypertonic (35 cases: increased integral tonicity coefficient up to 86 units and total peripheral vascular resistance over 3000 dyn/s·cm-5), hypotonic (35 cases: decreased integral tonicity coefficient down to 77 units and less, total peripheral vascular resistance less than 1500 dyn/s·cm-5, possible M-like waves of rheography curve) and intermediate (integral tonicity coefficient between 77 and 83 units, total peripheral vascular resistance between 1500 and 2000 dyn/s·cm-5). Integral tonicity coefficient between 80 and 113 units and total peripheral vascular resistance between 1500 and 3000±120 dyn/s·cm-5 were important indicators while monitoring for possible recurrent gastrointestinal bleeding. Conclusion. Blood loss compensation monitoring by continuous non-invasive rheography in patients at high risk for recurrent gastrointestinal bleeding allows not only diagnose recurrent gastrointestinal bleeding in a timely manner, but also to assess the effect of the treatment conducted.
