In the given research from the point of the system analyses is studied the haemodynamicy as an integral and one of the most leading factors affecting the safety of operating period by invasions under the circumstances of carboxyperitoneum by patients with heart problems. It is shown that similar nosological forms combine heterogenic patients' groups with different system reactions for carboxyperitoneum and surgical stress. Obese patients have a more impressive move of vegetative homeosthasis to the side of symphaticothony the centralization of the heart rhythmus ruling, the sharp decrease of the adaptational reserves. It should be noted that the differences at the level of stress-indicative hormones are also present and kept further at the early postoperative period

In the accomplished clinical-experimental research the results of studying coagulation, countercoagulation and fibrinolitic system and functional activity of thrombocytes during endovideoscopic invasions. Here are shown differences in the system of haemocoagulation at the local and system levels, the dependence of the current changes on the stress reaction level.
