There are many precautions for medullary opening anesthesia, which need to know whether there is a history of allergy, whether there is any underlying disease, and whether there is any disorder of coagulation mechanism and so on.
1. To know whether there is a history of allergy: mainly to ask whether the patient is allergic to anesthetics, if allergic to anesthetics, it is not recommended to open the medullary drainage, otherwise it is likely to cause anaphylactic reaction, and in severe cases, there is a risk of shock.
2. Whether there is any underlying disease: it is necessary to ask whether the patient has hypertension, diabetes, coronary heart disease, myocardial infarction, myocardial infarction, etc. These diseases are more serious, which may affect the effect of open medullary drainage, and should be changed to other methods of treatment.
3. Check whether there is any disorder of coagulation mechanism: if the patient himself has abnormal coagulation function, there is a risk of bleeding, and it is also not suitable for open medullary drainage, otherwise it will cause hemorrhage.
You also need to ask your doctor before doing open medullary paralysis and understand your own situation. If you check that you have problems, try to change to other ways to treat the disease under the guidance of your doctor.
