Adverse reactions and radiation treatment, radiotherapy is a local treatment, but can cause general malaise, fatigue, nausea, vomiting, these side effects are generally relatively minor. When there is exposure to red bone marrow hematopoietic function in certain areas, then the impact of bone marrow hematopoietic function, mainly to reduce white blood cells, under normal circumstances would not be very serious, if a large area of exposure may occur thrombocytopenia. Other adverse reactions include light parts of the skin lesions, the corresponding parts of organ damage produced by exposure to adverse reactions.
Radiotherapy and treatment of adverse reactions (1) skin lesions: is radiotherapy of the most common adverse reactions, but this generally does not result in serious injury aftermath effect. When using high energy X ray and treatment plan system, the skin lesions was significantly reduced. Acute skin damage. Acute skin lesions manifested as erythema, pigmentation, skin desquamation accompanied by itching, skin fall off gradually in the course of the gradual formation of new skin. For dry skin, this treatment can damage the local application of vitamin A or vitamin D ointment to apply. Another injury to the skin moist skin lesions, the performance of the water for the skin pain, effusion and pain, and in severe need to temporarily stop the radiation, the skin is exposed to air, or topical gentian violet sheds acid ointment. delayed skin damage. Delayed skin lesions mainly for skin pigmentation or hypopigmentation, telangiectasia and skin fibrosis. When the radiation dose exceeds the tolerance of the skin dose, skin necrosis can occur, prolonged unhealed ulcer formation, and often require skin grafting to repair.
Radiotherapy and treatment of adverse reactions (2) Gastrointestinal: gastrointestinal system tolerated dose of radiotherapy is low, when more than 5,000 Gy dose of radiation often radioactivity gastroenteritis, nausea, vomiting, abdominal pain, diarrhea. Radiation enteritis occurs when the rectum with abdominal pain, bloody stools and poor stool.
Radiotherapy and treatment of adverse reactions (3) Radioactive pneumonia: chest irradiation is a common complication. Lung tolerance dose of radiation is small, the radiation therapy of lung radiation injury almost inevitably occurs. Acute exudative manifestations of acute radiation pneumonitis, the main symptoms are irritating cough, long duration, if the infection is fever, cough, sputum. Performance of chronic radiation-induced lung injury in pulmonary fibrosis, the chest, suffocation-based. Need to use antibiotics in acute radiation pneumonitis and adrenal cortex hormone treatment; chronic pulmonary fibrosis is no specific treatment methods.
