The focus of the treatment of advanced cancer pain is to maximize the survival time under the premise of improving the quality of patient’s survival. In clinical work, we often come across this situation, the patient’s family members or relatives and friends through various relationships or channels to find clinicians to buy narcotic drugs – dulcolax, and when asked about its use, almost all of them are purchased for cancer patients. Since the state has a very strict control over the narcotic drug Dulcolax, if there is a cancer patient in the family, the family members have to go around the hospitals for Dulcolax through all kinds of relationships and doors. As a matter of fact, injection of Dulcolax to treat the pain of advanced cancer patients is a backward treatment method, which is not only addictive, but also reduces the quality of patients’ survival and shortens the survival time. With the continuous development of medical science and technology, many new drugs, new medical equipments and new technologies have been successfully used in the treatment of advanced cancer pain. They have not only improved the quality of patients’ survival, but also prolonged the survival time of patients to a certain extent. The key is that many hospitals have not yet carried out work in this area, and most of the patients do not know it very well. Therefore, as a medical worker who has been engaged in pain treatment for a long time, I think it is necessary to talk about the modern treatment of advanced cancer pain, hoping that hospitals at all levels can carry out new treatment means for cancer pain on the one hand, and enable people to understand the knowledge in this regard on the other. Cancer is one of the major diseases threatening human health, with 7 million cancer patients in the world and 1.8 million in our country, and more than 70% of advanced cancer patients are accompanied by severe pain. How does cancer cause pain in human body? Firstly, it directly invades the peripheral nerves; secondly, it produces pain-causing substances; thirdly, neurotrophic blood vessels are blocked by cancer cells, resulting in ischemia of nerves; fourthly, cancer tumors infiltrate the lumen of tubular organs or are accompanied by obstruction, ischemia and spasm of the lumen of tubular organs. Fifthly, the pressure of cancerous tumor on its neighboring organs; sixthly, the necrosis and infection of cancerous tumor itself. If pain is not controlled, it may cause many harms to human body: ① Vicious circle of pain, aggravating local ischemia. ② Sympathetic nerve excitation, accelerated metabolism and increased consumption. ③Neuroendocrine dysfunction, affecting organ function, especially on the cardiopulmonary function. ④ Decrease in appetite, gastrointestinal dysfunction, malnutrition. ⑤ Impact on sleep and rest, long-term insomnia will lead to plant nervous system dysfunction, accelerate organ failure. ⑥ Increase the patient’s psychological burden, weaken the confidence in treatment, so that many patients are negative or refuse treatment. What are the disadvantages of Dulcolax injection? First, Dulcolax belongs to narcotics, addictive, once addicted, even if the patient is not painful, but also a strong demand for injections; second, easy to produce drug resistance, the beginning of the day one or two injections, a long time an hour or two will have to be injected once; third, Dulcolax injections, the patient drowsiness, unconscious, and even nausea, vomiting, loss of appetite, greatly reducing the quality of survival; fourth, the interval between injections of the patient is still pain; fifth, Dulcolax injections, patients are still in pain; fifth, Dulcolax injections, patients have a lot of pain. Fifthly, Dulcolax has respiratory inhibition, which can accelerate the death of patients with poor cardiopulmonary function; Sixthly, it is easy to aggravate the psychological burden of patients, because most people have the common sense that as long as they start to play Dulcolax, they will not be far away from death. The treatment of advanced cancer pain should be comprehensively analyzed according to different kinds of diseases, different parts, different degrees, different ages and different medical conditions, so as to adopt the most reasonable treatment methods. Generally speaking, it is divided into three steps: first step, mild pain, if the site is limited, local treatment is mainly used, such as local closure and local nerve necrosis. If the site is more extensive or the site is uncertain, oral non-opioid drugs such as: aspirin, pain tablets, tramadol, etc.. The second part, moderate pain, the site is limited to those who are still mainly localized treatment, if the site is more extensive or the site is uncertain, oral weak opioid drugs such as: codeine, Lugubrizol and so on. The third step, severe pain, now advocate a new treatment means, called patient-controlled analgesia (PCA). Is the pain medication into a special pump (pump size similar to a small tea cup), a fine catheter into the body, the pump drugs through the fine catheter to a specific speed automatically injected into the body, the injection rate can be selected (0.5 ml/hour, 1 ml/hour, 2 ml/hour and 4 ml/hour), the pump there is a patient self-control buttons, when the patient feels the pain when the patient presses There is also a patient-controlled button on the pump, so when the patient feels pain, he/she can press it a few times to increase the amount of medication injected. The thin catheter can be inserted into the patient’s spinal canal, blood vessels, under the skin or next to the nerves, depending on the situation, and must be operated by pain or anesthesiologists, and can be maintained for one to three months if properly cared for. The pain medication in the pump can last for about two to seven days when added once, and if the patient is not hospitalized, the medication can be added by the local doctor according to the formula. Advantages of treating cancer pain with analgesic pump: Firstly, the pain-relieving effect is good, and most patients basically do not feel pain. Secondly, it is less painful and can be maintained for one to three months after one puncture. Thirdly, it does not affect patients’ consciousness, basically does not affect patients’ daily activities and does not reduce patients’ appetite, thus improving the quality of survival and prolonging patients’ life. Fourth, but because of less medication, do not need to find a doctor every day, the patient can take the pump home, hospitalized or not. Fifth, save time and cost less, although the first time according to the pump cost higher (600 ~ 800 yuan) total cost is low. Of course, the analgesic pump is not perfect, there are certain shortcomings and side effects: the pump needs to be brought on the body, wearing and undressing and sleeping with a certain impact, if not careful pipeline there is a possibility of disengagement; the beginning of the application of the part of the patient there will be nausea, difficulty in urination, itchy skin and chest tightness and other side effects. In order to better treat the pain of cancer patients, in addition to the above methods should be combined with other corresponding treatments, such as: patient’s psychological treatment, radiotherapy, strengthening nutrition, local physiotherapy and important auxiliary treatment of traditional Chinese medicine.
