When patients with lung cancer undergo chemotherapy, skin care should be taken in time where drugs are used externally. Drugs used for chemotherapy of lung cancer are harmful chemicals. According to the chemical properties of chemicals, the damage to blood vessels of lung cancer patients and the skin and subcutaneous tissue after extravasation are different. Therefore, if patients have drug extravasation after chemotherapy, they must be treated in time to avoid the skin blackening and ulceration after chemotherapy care for lung cancer. For the position of needle mouth, you can use sterilized towel for hot compress nursing, which can promote the blood circulation of lung cancer patients, reduce the burning sensation caused by chemotherapy and relax muscles.

When lung cancer patients receive chemotherapy, chemical drugs can cause nausea, vomiting, abdominal pain and diarrhea. Therefore, the nursing after chemotherapy should pay attention to the reasonable arrangement of patients' diet, give patients some light food, and don't eat too much. If vomiting is serious and lung cancer patients can no longer eat, intravenous nutrition should be given at this time to ensure a balanced nutrition. In the process of nursing, we must ensure that lung cancer patients have enough nutrition to avoid the decline of patients' resistance due to lack of nutrition. Pay attention to the diet care of patients with lung cancer after chemotherapy, because chemotherapy makes patients weak, listless and sleepy at ordinary times. At this time, patients should be supplemented with nutritious food and high-protein diet, such as trotters, sea cucumbers, fish, milk, soybeans, lean meat, animal liver, auricularia auricula, carrots, red beans, red dates, peanuts, walnuts and other rich foods in protein. In addition, beef, crab, snakehead, boiled pigskin glue, pig bone marrow stew, or chicken blood, duck blood, goose blood and other foods can supplement the liver nutrition of lung cancer patients and improve liver function. Chinese medicine suggests that patients with lung cancer should eat more black food such as black beans, black dates, black sesame seeds and black rice during the nursing process after chemotherapy. These foods have the function of tonifying kidney and filling marrow. In a word, in the diet nursing after chemotherapy for lung cancer, supplementing lung nutrition and nutrition of other organs of patients with lung cancer can comprehensively improve their physique and enhance their anti-lung cancer ability. After chemotherapy for lung cancer, on the one hand, the rapid decline of lung cancer patients' system brings side effects to patients, on the other hand, patients' subconscious fear of chemotherapy will make patients become negative and depressed. At this time, active psychological care will be carried out to let patients know that chemotherapy is to kill cancer cells and drive lung cancer tumors away from the body. As for the side effects of chemotherapy for lung cancer, they will disappear with the improvement of the condition. Let patients summon up courage, face lung cancer with a positive attitude and face the next treatment. The only purpose of chemotherapy for lung cancer is to inhibit and eliminate cancer cells.
