Intractable pain

Introduction Pain and pain is one of the most common clinical symptoms, and various diseases can cause pain, involving complex neuroanatomy, neurophysiology, and biochemistry. Intractable pain: trigeminal neuralgia, postherpetic neuralgia, disc herniation, intractable headache, reflex sympathetic atrophy, cancer pain. There are also some headaches, low back pain, joint pain, etc. If you do not get timely and effective treatment, it will become a complex local pain syndrome or central pain from local long-term common pain, and the pain becomes very intense. It becomes a refractory pain disease. For these patients, correct surgical intervention can eliminate or reduce pain and improve the quality of life of patients.

Cause

Intractable pain is mainly seen in two situations:

One is neuropathic pain, that is, the lesion or pain affects the peripheral nerve or central nervous system, such as shoulder and neck pain, migraine, lumbosacral pain, pain caused by diabetes, etc.;

The second is cancer pain, more than 60% of tumor diseases are accompanied by pain, and it is severe pain. Intractable pain afflicts people to eat badly, sleep poorly, not work and live, and even cause disability and suicide.

Pain is one of the most common clinical symptoms, and all kinds of diseases can cause pain. Pain associated with functional neurosurgery means that the cause of the pain is unknown or cannot be removed. Pain as the main symptom of the disease cannot be controlled by other methods for a long time, leading to a series of serious personal, social and economic problems, which need to be considered through surgery. Methods to relieve painful intractable pain, such as central pain, cancer pain, vascular disease pain.

Pain involves only complex neuroanatomy, neurophysiology, and biochemistry. There are many ways to treat pain. Early destructive surgery such as spinal cord conduction severing, spinal nerve root resection, and stereotactic brain core mass destruction achieves the purpose of blocking conduction by destroying the normal nerve structure on the conduction pathway. Inevitably, it will cause certain permanent neurological deficits. At present, it is gradually replaced by reversible stimulation such as deep brain stimulation (DBS), spinal cord stimulation (SCS), and chronic motor cortex stimulation (MCS). instead. The therapeutic effect of pain surgery is significantly improved.

Diagnosis of intractable pain:

Pain is an unpleasant reaction of the body to damaged tissue or potential damage. It is a complex physiological and psychological activity and one of the most common symptoms in the clinic. It consists of two parts: pain and pain. Pain can be used as a warning to the body's injury, causing a series of defensive protective responses. On the other hand, pain has its limitations as an alarm (it is too late when there is pain such as cancer). And some long-term severe pain has become an unbearable torment.

Differential diagnosis

Differential diagnosis of intractable pain:

1, acute pain: soft tissue and joint acute pain, postoperative pain, obstetric pain, acute herpes zoster pain, gout;

2, chronic pain: soft tissue and joint strain or degenerative pain, discogenic pain, neurogenic pain;

3, intractable pain: trigeminal neuralgia, postherpetic neuralgia, disc herniation, intractable headache;

4, cancer pain: advanced tumor pain, tumor metastasis;

5, special pain categories: thrombotic vasculitis, refractory angina, idiopathic chest and abdominal pain;
