Parkinson’s disease is a chronic disease of the elderly that is treated slowly, with a variety of treatments going hand in hand. These include medication, surgery, and rehabilitation. In the early stages of Parkinson’s disease, medication is the mainstay of treatment, and when the honeymoon phase of medication occurs, it is necessary to begin to consider surgical treatment, i.e., deep brain electrical stimulation surgical treatment. Deep brain electrical stimulation surgery can make the symptoms of Parkinson’s disease patients get effective control, and even reduce the dose of medication, so before the operation Parkinson’s disease patients need to do what preparation? 1, the doctor to understand the condition: different symptoms to choose different surgical methods Therefore, the patient in the preoperative period to the doctor to reflect their clinical performance. Tell the doctor about their cardiopulmonary function, history of hypertension, history of diabetes and history of cerebrovascular accidents. Tell the doctor about taking anti-Parkinson’s disease drugs. The doctor routinely measures blood pressure for 3 to 4 days before the operation, checks the electrocardiogram, takes chest radiographs, and checks the liver and kidney functions. If there is high blood pressure, anti-hypertensive drugs should be taken to stabilize the blood pressure. If there is cough, pay attention to cough treatment, in order to avoid intraoperative and postoperative cough induced intracerebral hemorrhage, the relevant experts remind patients that it is best to have Parkinson’s symptoms, immediately on Parkinson’s treatment. 2, make good psychological preparation for the operation: there is enough psychological preparation before the operation, in order to cooperate with the doctor during the operation, which is also the key to the success of the operation. Understand the surgical process, eliminate ideological concerns. Doctors and family members of patients with low confidence should do a good job of patient and meticulous ideological work to encourage the establishment of confidence in overcoming the disease. Some Parkinson’s disease patients with depression and other mental symptoms, fear of surgery, in addition to continue to take antidepressant drugs, strengthen mental care, so that patients have confidence in life. 3.Preoperative medication: the night before the surgery, you can take sedative medication appropriately. On the day of surgery, sedatives and atropine are not needed, but patients with hypertension should continue to take anti-hypertensive drugs. Discontinue the use of anticoagulant drugs and blood-activating drugs, such as enteric aspirin, before surgery. Surgery is usually performed without the pharmacologic effects of anti-Parkinson’s disease medications so that efficacy can be observed during surgery. Therefore, antiparkinsonian medications should be discontinued on the day of surgery. However, if the symptoms of tremor and rigidity are serious and affect the surgical operation, especially the magnetic resonance examination, the operation can be carried out after taking the drug, but the specific dose of the drug should be flexibly controlled, so as to achieve neither affecting the surgical operation nor observing the efficacy during the operation. Keep the bowel clear before the operation, and the urine should be emptied before the operation. Preoperative head preparation, fasting, timely understanding of Parkinson’s symptoms, help to treat Parkinson’s as soon as possible.
