Clammy extremities

Introduction Patients with pulmonary embolism or septic shock have the performance of wet and cold limbs - that is, wet limbs. Sepsis syndrome caused by products such as microorganisms and their toxins is accompanied by shock. The clinical manifestations of pulmonary embolism are diverse. Actually, it is a broad clinical spectrum. The main factors are determined by the number of vascular occlusions, the speed of occurrence and the basic state of cardiopulmonary, and the lighter 2-3 segments can be without any symptoms. In severe cases, 15 to 16 lung segments can occur in shock or sudden death.

1. Infectious shock: Except for a few cases of high-ranking and low-resistance shock (warm shock), most patients have sympathetic excitation symptoms: the patient is clear, but irritated, anxious, nervous, complexion and pale skin, lips and nails The bed is mildly purpura and the limbs are wet and cold. Can have nausea and vomiting. Reduced urine output. The heart rate increases, the breathing is deep and fast, the blood pressure is normal or low, and the pulse pressure is small. Arterial spasm can be seen in the fundus and nail fold microcirculation.

2, pulmonary embolism

Four clinical syndromes:

1 acute pulmonary heart disease: sudden dyspnea, sudden death, cyanosis, right heart failure, hypotension, wet limbs, seen in patients with sudden embolization of the two lungs.

2 pulmonary infarction: sudden difficulty breathing, chest pain, hemoptysis and pleural friction sound or pleural effusion.

3 The relatively small area of the embolization is the only symptom that suggests an increase in the ineffective lumen.

Differential diagnosis

Cooling of the extremities refers to a decrease in body temperature due to insufficient blood perfusion in the peripheral tissues of the extremities. Because the blood is emitted by the heart, carrying oxygen to all parts of the body, oxygen can be burned before it can generate heat, and the hands and feet will be warm. Once the function of the cardiovascular system is impaired, it will affect the blood transport and cause cold hands and feet. The view of Chinese medicine that chills in the limbs is a yang deficiency. Yang Qi can not be exhilarating, caused by warm limbs.

Alternating cold and hot: can be seen in many common diseases, such as colds, malaria and so on. The alternating cold and hot caused by influenza is an acute respiratory infection caused by influenza virus. Early symptoms include dry itching or burning sensation in the throat, sneezing, stuffy nose, and salivation. Some patients may feel alternating hot and cold, taking cold sweat. Typical malaria is a periodic episode, manifested as an intermittent episode of cold.
