Gastric ulcer bleeding, and cold sweat
Patients with upper gastrointestinal bleeding, usually manifested acute peripheral circulatory failure.
Early shock, due to reduced blood volume, so that cardiac output decreased blood supply reduction in tissue hypoxia. At this point the body to make a variety of compensatory responses, such as the sympathetic nervous excitement, adrenal cortex and medulla, and pituitary function of enhanced catecholamine and 5 – hydroxytryptamine secretion increased, heart rate. Contraction of small arteries and capillaries, blood in the body and re-distribution, the performance of the body surface of the blood vessels contract, to ensure the heart, brain and other vital organs of the blood supply. The patient’s skin due to vasoconstriction and blood perfusion result of inadequate gray, cold and wet. Therefore, patients with ulcer bleeding patients with a cold sweat, often means that a larger amount of bleeding, lack of effective circulating blood volume, is entering the early state of shock indicators, should arouse the clinician’s attention.
At this point should be immediately added blood volume and, if the conditions, the best input of fresh whole blood or plasma and plasma substitutes, hemostatic should be selected so that local vasoconstriction without affecting the blood pressure drugs, pay attention to the maintenance of water and electrolyte balance, and promptly correct the acid poisoning, so that shock be corrected as soon as possible. At the same time pay attention to the patient’s blood pressure, pulse changes and mental state.
