Clammy skin

Introduction The skin is wet and cold often seen in shock and acute organophosphorus poisoning. When the skin of the limbs is pale, wet and cold, the color of the nails or lips is pale, and the redness is slow after the compression, indicating that the peripheral circulation is poor, and shock still exists. The patient is conscious, but restless, anxious or excited, pale complexion and pale skin, lips and nail bed slightly bluish, cold sweat, cold limbs, nausea, vomiting, rapid heartbeat, pulse systolic pressure, low or Close to normal, but also due to increased secretion of catecholamines but high but unstable; diastolic blood pressure is increased, so pulse pressure is reduced, urine output is also reduced.

Cause

Loss of blood and fluid loss, burns, trauma (all three have the characteristics of reduced blood volume), poisoning, infection, allergies, acute heart failure, strong nerve stimulation.

Reduced blood volume is seen in hemorrhage, shock, burns, and electrolyte imbalance; red blood cell volume and plasma volume decrease in aplastic anemia; red blood cell volume decreases in various anemia patients; red blood cell volume decreases and plasma volume increases during pregnancy anemia. Pheochromocytoma, cirrhosis, malnutrition and other red blood cell capacity reduction; when the pituitary function is low, the blood volume is reduced, about 50% to 70% of the normal blood volume.

1 has the cause of shock.

2 consciousness is abnormal.

3 pulse faster than 100 times / min, fine or can not be touched.

4 limbs wet and cold, sternum skin pressure positive (after refilling time is more than 2 seconds), skin pattern, pale mucous membrane or blemishes, urine volume less than 30ml / h or no urine.

5 systolic pressure is less than 10.64 kPa (80 mmHg).

6 pulse pressure is less than 2.66 kPa (20 mmHg).

7 The original systolic blood pressure of the original hypertension decreased by more than 30%.

A diagnosis can be established if one of 1, 2, 3, 4, and 5, 6, or 7 is met.

Differential diagnosis

Hyperhidrosis of the skin: It is a disease caused by excessive secretion of sweat glands caused by excessive stimulation of the sympathetic nerves, and the sympathetic nerves dominate the body's sweating. Under normal circumstances, the sympathetic nerve regulates the body temperature by controlling sweating and cooling. However, sweating and facial flushing in hyperhidrosis patients completely lose normal control, and hyperhidrosis and facial flushing make the patient feel helpless, anxious or panic every day.
