How is cerebral infarction convalescent period hand swollen to return a responsibility?
summary
Cerebral infarction is a common chronic disease. Why does the limb of hemiplegic side of cerebral infarction swell is a problem that clinicians often encounter and patients' families often raise. So how is cerebral infarction convalescent period hand swollen to return a responsibility? Let's talk about it.
How is cerebral infarction convalescent period hand swollen to return a responsibility?
1、 Venous reflux disorder: the body's blood supply is completed by the circulatory system. The circulatory system includes the heart and blood vessels. The blood vessels of the whole body are composed of arteries and veins. Fresh blood was infused into tissue cells by artery; Veins return the body's used blood back to the heart. The power of arterial blood flow comes from every powerful contraction of the heart and the elasticity of the vascular wall; The venous return mainly depends on the pressure difference between it and the heart, as well as the squeezing force of muscle contraction on the vascular wall. Because the vein wall is thin and the elasticity is poor, the effect of this kind of squeezing force is particularly important. But when the limbs are paralyzed; Because the muscle loses its innervation, it stops its contractile activity. Therefore, the squeezing force of the muscle on the venous vessels disappears, resulting in the obstruction of venous return.
2、 Nutritional metabolic disorder: human limb activity is innervated, and the vasomotor function is also innervated. When the limb is hemiplegic after cerebral infarction, it loses the innervation, and the limb on the hemiplegic side of cerebral infarction will be secondary to nutritional metabolic disorder, which makes the vasomotor function maladjustment, the contractile and diastolic response become slow, and the speed of venous blood return slow.
3、 Local edema of the lower extremity may be caused by venous thrombosis. The above reasons lead to the blood can not return to the heart quickly, and the amount of blood stasis in the vein increases, the pressure in the vein lumen also increases, the liquid is easy to be squeezed to the wall of the blood vessel, staying in the tissue gap, so swelling occurs. Mild limb swelling, through improving the conditions, let the venous blood return to the heart as soon as possible, edema will disappear quickly, will not produce greater harm. On the contrary, if the edema stays in the tissue for a long time, the protein components will deposit and become fibrous tissue. If the lesion occurs around the joint, stiffness and contracture can occur.
matters needing attention
First of all, we should often move passively and massage the affected limbs. Through rubbing, kneading, kneading and pressing, the muscle can be replaced to move actively, so as to achieve the function of squeezing the venous blood vessels, promote venous reflux, improve microcirculation, and correct the nutritional and metabolic disorders of the affected limbs. Secondly, we should pay attention to raising the affected limb position. When sitting, we should use a bracket or other support to raise the forearm, or put it on the armrest of the chair. In supine position, the affected lower limb should be raised by 10-20 cm to reduce the influence of gravity on perfusion and promote venous blood return, so as to reduce the swelling of the affected limb. According to the etiology of cerebral infarction treatment: cerebral infarction regardless of limb disorders and the resulting limb swelling, or language disorders, eating difficulties and other symptoms, the root cause is in the brain. So if we want to really treat the symptoms, the symptomatic treatment of cerebral infarction is the key. For the treatment of cerebral infarction, we must choose the most reliable and healthy drugs from comprehensive hospitals, Internet and other sources.
