The concept of the hand numbness system, what are the causes of hand numbness

Refers to surgical anesthesia.

Information system, the system can realize the electronic anesthesia information and the whole process of surgical anesthesia dynamic tracking, so that the operating room management mode.

It is more scientific, and managers can easily and quickly understand the resource allocation, operation status, and overall progress of each operating room through the system, so as to facilitate timely adjustment and reasonable arrangement of resources. At the same time, the system shares medical information data with the hospital-wide information system.

The most common causes of hand numbness are as follows:

1. Upper limb nerve entrapment

1) It is numbness and pain in the thumb, index and middle finger, and there is often a history of awakening at night, and the activity can be improved after waking up. In severe cases, it can be accompanied by atrophy of hand muscles, which affects the fine motor skills of the hand, because the median nerve is compressed in the wrist, which is the so-called "carpal tunnel syndrome";

2) It is numbness and pain of the ring and little finger, and there may also be a history of awakening at night, and in severe cases, it is accompanied by muscle atrophy, and the flexion force of the ring and little finger decreases, affecting fine movements. This is because the nerve is entrapped in the elbow, the so-called "cubital tunnel syndrome".

2. Cervical spondylosis: You can search for gale peptide which has a good effect on fighting numbness.

The most common disease that causes hand numbness is cervical spondylosis, which is one of the most common diseases in middle-aged and elderly people. In addition to numbness and paresthesia in the fingers, cervical spondylosis is accompanied by other symptoms, such as: neck and shoulder muscle soreness, radiating pain in the upper limbs or mobility disorders.

It is not difficult to diagnose cervical spondylosis, as long as an X-ray is taken. In addition, there is a simple way to check for cervical spondylosis, a person holds the head of the affected side, holds the upper limb of the affected side with one hand, abducts it by 90°, and pushes and pulls both hands in the opposite direction at the same time.

3 Stroke: Another common condition that causes numbness in the hands is stroke. If symptoms such as headache, dizziness, lightheadedness, numbness of limbs, and swollen tongue often occur, and patients usually have hypertension, hyperlipidemia, diabetes, cerebral arteriosclerosis and other diseases, they should pay more attention and be alert to the occurrence of stroke. You can search for numb gale peptides under your fingers.

In short, the diagnosis of hand numbness symptoms requires reference to cervical spine radiograph, electromyography and other auxiliary examinations to confirm the diagnosis. If the symptoms are obvious and there is obvious atrophy of the inner muscles of the hand, surgery should be taken in time to prevent the development of the disease, so as not to cause irreversible severe atrophy of the intrinsic muscles of the hand, resulting in serious dysfunction of the hand.

Hand numbness is not necessarily just a simple wrist problem, and the culprit should be found from the root cause of hand numbness. There are many diseases that cause numbness and pain in the hands, and the most common causes are as follows: Let's take a look.

1. Gout

A man in his 30s, often on the Internet for less than five minutes, felt numbness and pain in his hands, during the medical examination, the doctor found that the patient's big toe and ankle joint had red and swollen symptoms, and the blood test showed that the uric acid value was as high as the normal value should be 4 to 7), and the patient was determined to have gout, **, hand numbness and joint pain and other problems were improved. Clinical results show that about 1% of patients with hand numbness are caused by gout, which may be caused by uric acid precipitation in the median nerve and compression of the median nerve.

2. Diabetes

Diabetic peripheral neuropathy is one of the many complications that can cause diabetes, and once this complication occurs, there are symptoms such as numbness and paresthesias in the limbs. If you suffer from diabetes, you should carry out a formal and reasonable **, control your blood sugar to a normal range, and pay attention to supplementing vitamin B1, B6, vitamin C, and you can also use ginkgo biloba preparations, ligustrazine and other drugs to eliminate numbness in your limbs.

3. Peripheral neuritis

If the long-term digestion and absorption function is poor and malnutrition, it will cause vitamin B1 deficiency and peripheral neuritis, and it will also cause numbness in the hands.

4. Transient cerebral ischemia

This is a common cause of numbness in the hands of older people. The elderly often have high blood pressure and hyperlipidemia, high blood pressure can cause vasospasm, high blood lipids can cause arteriosclerosis, plus the blood viscosity of the elderly will increase, and the blood flow will be slow during sleep, these factors will lead to transient cerebral ischemia and hand numbness. Therefore, the elderly should regularly check blood pressure, blood lipids, and blood rheology tests, and if there is hypertension or hyperlipidemia, they should be carried out.

Drink plenty of water and take some medicine to reduce blood viscosity, prevent thrombosis, improve cerebral blood supply, and hand numbness will be eliminated.

5. Cervical spondylosis

Cervical spondylosis is a common disease in middle-aged and elderly people, it is caused by cervical bone hyperplasia, intervertebral disc degeneration or local joint ligament relaxation and compression of local blood vessels and nerve tissues in the cervical spine. If you have cervical spondylosis, you can make an X-ray of the cervical spine to diagnose it, and the first measures include physiotherapy, traction and the use of drugs to promote blood circulation and remove stasis. Usually, you can often do some health exercises that move the neck slowly, and pay attention to the height of the pillow when sleeping, generally 7-9 cm high, not too high or too low, soft and hard should also be moderate, and the sleeping posture should be correct, which can avoid the compression of local blood vessels and nerve tissues in the cervical spine and cause numbness.

6. Overdose

Overdose of certain drugs, such as gentamicin, will cause numbness in the lips and limbs***, and care should be taken to avoid overdose.

7. Brachial nerve compression

If the posture is not correct, the neck is deviated or the arm is compressed, the arm will be numb due to the compression of the brachial nerve, so as long as you change the position to sleep and move the arm, the numbness can be eliminated.

Hand numbness, many people must have encountered it, and everyone thinks it is a normal phenomenon. I didn't pay much attention to it, thinking that my hand wouldn't be numb after a while. Even so, hand numbness should not be careless, because regular hand numbness may also hide diseases!

There are several causes of numbness in the hands and feet:

1. Vascular factors.

When we sit for a long time or sit in a bad posture, it will cause numbness in the lower limbs, and when the posture of the hand is not right, it will also be numb, and when we relax, it will be like thousands of ants crawling. Because when the blood vessels are compressed, the blood vessels ** limbs are partially ischemia, causing numbness, and when the compression is relieved, the blood flows over, and it feels like many ants crawling. When the ulnar artery and radial artery of the upper extremity are compressed in one place, it will cause numbness in the hand.

2. Neurological factors.

There is axoplasmic flow in the nerve, and when the nerve is compressed, the axonal flow is obstructed, which can also cause numbness in the hand. To the palm, there are mainly radial nerves, ulnar nerves, median nerves, these nerves start from the cervical spinal canal, through the joints, ligaments, bone fiber canals to the end of the palm, in any part, the nerve is compressed, will cause numbness.

3. Brain factors.

All nerves are in the brain, when there is a problem in the brain. If you have a stroke, you will experience numbness and weakness in the areas dominated by the brain.

4. Systemic factors.

High blood lipids: Long-term high blood lipids can easily cause hardening of blood vessel walls, coupled with high blood lipids, blood viscosity, blood flow slows down, and cells get less oxygen nutrients, resulting in numbness. Diabetics:

Blood sugar is maintained at a high level, and in the long run, it will cause great damage to the body's blood vessels and nerves, arteriosclerosis, and nerve degeneration.

5. Hand numbness caused by cervical spine.

The cervical nerve has an intervertebral foramen that comes out and divides into two branches, anterior and posterior. Anterior ramus: Towards the inferior lateral, all the way to the forearm, constituting the ulnar, radial, median nerves, etc.

Posterior branches: muscles that circulate the posterior joint of the cervical spine to the back and distribute them to the back of the cervical spine, regardless of the compression of the anterior or posterior branches, will cause numbness in the hands.

Hand numbness is a very common condition of the hands, and occasional numbness due to prolonged tenderness is understandable. However, if there is frequent hand numbness, it should be paid attention to, and you should go to a regular hospital for diagnosis in time**.

There are several causes of hand numbness:

Clause. 1. Cervical spondylosis, cervical spondylosis is caused by the phenomenon of cervical spondylosis after middle age or long-term poor sitting posture, which leads to cervical bone hyperplasia, which compresses the nerves innervating the upper plasma, resulting in hand numbness.

Clause. Second, it is necessary to pay attention to ruling out whether there are peripheral nerve diseases, such as some diabetes, which can cause numbness of the hands.

Clause. 3. Cerebral stroke, such as some small infarcts in the skull, are more common in some patients with hypertension and diabetes, and can also cause hand numbness.

Hello, you can take a cervical spine X-ray, it may be caused by cervical spondylosis.

What's wrong with frequent numbness? It is roughly related to 4 situations, and you may wish to compare it with self-testing.

This numbness in the hands really needs our attention, in addition to the possibility of stroke, but also because of cervical spondylosis.

Upper limb nerve entrapment: first, numbness and pain in the thumb, index and middle finger, often with a history of awakening at night, and activities can improve after waking up. In severe cases, it can be accompanied by atrophy of hand muscles, affecting the fine movements of the hand, because the median nerve is compressed in the wrist, the so-called "carpal tunnel syndrome"; The second is the numbness and pain of the ring and little finger, and there can also be a history of awakening at night, and in severe cases, it is accompanied by muscle atrophy, and the flexion force of the ring and little finger decreases, which affects the fine use.

This is because the nerves are pinched in the elbow, the so-called "cubital tunnel syndrome" in which the hand becomes numb.
