Bleeding in the stool accompanied by a decrease in blood pressure may be related to hemorrhagic shock, in which case blood volume can be supplemented in time to maintain stable blood pressure and then hemostasis can be carried out. If the effect of internal medicine treatment is not good or bleeding still occurs, endoscopy or surgery is needed to stop bleeding.
In case of low blood pressure or even shock caused by large amount of bleeding from stools, the first infusion of balanced fluid or glucose saline can be used to expand the volume to maintain tissue perfusion and correct the shock. Blood matching is carried out at the same time as infusion, and blood transfusion is carried out in time to keep hemoglobin above 70g/L is appropriate. At the same time, use snake venom hemagglutinin, growth inhibitor and other drugs to stop bleeding treatment.
If there is still persistent bleeding after drug treatment, endoscopic or interventional hemostatic treatment can be carried out, and if the bleeding still can not be stopped, surgical hemostasis must be carried out in time to save life.
Therefore, when there is bleeding in the stool with decreased blood pressure, it is necessary to seek medical treatment in time to avoid delaying the condition.
