Cancer Pain and suffering

 In recent years, the anatomy of pain, physical, psychological, pharmacological and clinical studies conducted extensive. In terms of neural anatomy, we have to understand the pain neural pathway. From organizations of noxious stimuli to produce pain in the nervous system a series of electrical and chemical changes, electrical signals through the spinal cord, brainstem, and thalamus of the transmission and regulation, and finally produce pain in the cerebral cortex. In the past people want to find a message to the brain to the pain pathway, so only will be cut off to eliminate the pain pathway. neurosurgeon cut off by surgery trying to remove the spinal cord pathways intractable pain, but the results disappointing. For example, the lower body from the pain caused by cancer, the surgical removal of the spinal cord, the results of only 50 % of patients pain relief, but effective treatment in these patients, but also the dramatic emergence of new mainly refers to the exercise of selective effect on pain to stop the neural network system. gate is the core doctrine of the phase modulation of the spinal cord. opioid drugs are widely used in classical clinical pain medicine, body found, endogenous opioid peptides and opioid receptors, opioid pain transmission to the spinal cord is modulated. From the above findings and research shows that pain is a common symptom of a very complex clinical, contains extremely fine nerve conduction and modulation, fantasy through simple methods to control Pain is not realistic, as the clinician should have sufficient knowledge of this, only with a particular aspect of technology to the face of such complex pain problems, may feel powerless.
pain is an unpleasant experience, with substantial or potential tissue damage. Although the mechanism of pain people are gradually understanding and research, but everyone's feelings and expression of pain is different, because the pain is a subjective experience, will be affected by the patient's mental state and cultural background, social environment. pain intensity and extent of tissue damage or non-proportional type of relationship. cancer pain and non-malignant chronic pain caused by different diseases, cancer pain patients, most people fear is that frequently remind patients face disease and death. When the patient pain, the first thought is there a proliferation of the tumor, the condition is deteriorating, life to the end. The patient may experience depression, anxiety or fear and other psychological problems. pain, such as ineffective mitigation, can make the patient sleep, loss of appetite, weight reduction, severe fatigue and weakness, after a few weeks later, the patient was subdued by pain, when patients often complained of vague aches and pain. how to block the insomnia - fatigue - Pain - The vicious cycle of insomnia is the most important treatment chain content.
pain is a threat to lasting self-image and sense of life, is a cancer symptoms and problems caused by the performance of helpless, is a sense of loss, is the lack of the cornerstone of hope. suffering and pain can not be exactly the same, short-term patients, the prognosis is good, clear cause of pain can be tolerated, such as arthritis, disc prolapse, herpes zoster, although severe pain, but patients often have no pain issues because the patient know that pain is not the risk of life. But if the patient knows the pain of the disease is difficult to control, the prognosis is poor, a serious life-threatening, the pain is difficult to tolerate, often causing the patient pain. pain, including somatic pain, but not limited to this, the main thing is, including the psychological factors, is a man threatened the integrity of the state of extreme distress.
cancer pain is one of the main causes of pain, patients with end-stage pain, often in pain relief before they can get a real lift. In fact, there is pain may occur without any symptoms, such as witnessing a loved one's physical condition deteriorated and feel the pain of heart, this time, no body injury and pain, but the psychological pain is very severe, there will be a painful expression. So psychological feeling of pain is a human experience rather than the body, pain can be treated by the disease can also be caused by cancer patients pain can lead to one of the causes of pain patients, but the fear of cancer, the treatment effect of hopelessness, can lead to the patient's pain, and pain at this time of pain the patient is often aggravated factors. Therefore, in order to determine the pain the root causes of disease need to consider not only factors, but also need to conduct a comprehensive psychological evaluation of the patient.
in the clinical treatment of cancer pain patients, the need to pay attention to identify the patient's pain and suffering issues, simply can not be completely analgesia relieve pain, but effective analgesic treatment can help relieve pain. Patients should be fully concerned about the suffering of cancer pain problems, adopt a comprehensive treatment of methods to control pain and suffering, improve the quality of life of patients.
