Precautions for peripheral neuritis include diet, hygiene, bed care, protection of limb function, maintenance of temperature and correct posture. 1. Diet: Pay attention to eating foods that are easy to digest and contain vitamin B. As far as possible, don’t eat seafood and other foods that are easy to cause allergies, and prohibit eating spicy and stimulating foods. 2. Hygiene: keep the mouth clean and the respiratory tract open. 3. Bed rest: In the acute stage, you should rest in bed and take good care of your skin to prevent pressure sores from occurring. 4. Protect the function of limbs: paralyzed bedridden people should be fixed in the functional position of limbs to prevent contracture and deformity of limbs. 5. Maintain comfortable temperature: pay attention to keep the limb ends warm and prevent burns. 6. Maintain correct posture: avoid prolonged squatting, stilting legs, elbow joint over-extension and other actions, so as not to produce nerve entrapment syndrome. It is recommended to standardize the treatment under the doctor’s guidance and follow the doctor’s instructions to actively carry out rehabilitation training in daily life.
