Body heat infusion chemotherapy generally refers to peritoneal heat infusion chemotherapy, the “bad” side effects of which mainly include abdominal pain, abdominal distension, nausea, vomiting, intestinal adhesion, bone marrow suppression and so on. Intraperitoneal heat infusion chemotherapy is to use high temperature (between 42 and 45℃) to inject chemotherapeutic drugs into the abdominal cavity to kill tumor cells in the abdominal cavity, which plays a role in treating tumors. It is suitable for patients with diffuse spread of tumors in the abdominal cavity. The side effects caused are mainly the adverse reactions of the infused chemotherapeutic drug itself, such as. 1. Abdominal pain and distension: the drugs and high temperature stimulate the peritoneum, which triggers the symptoms of abdominal pain and distension. 2. Nausea and vomiting: chemotherapeutic drugs stimulate the stomach and intestines, causing digestive reactions and loss of appetite. 3. Intestinal adhesion: the peritoneum will be stimulated by the heat perfusion chemotherapy in the abdominal cavity, and intestinal adhesion will appear, and in severe cases, there will be intestinal obstruction, which will be manifested as abdominal distension, abdominal pain, nausea and vomiting, and stopping of defecation and bowel movement. 4. Bone marrow suppression:Some drugs can cause bone marrow suppression, granulocytopenia, anemia and so on. In addition, too high a temperature of the liquid in the abdominal thermal perfusion will damage the abdominal tissue, and too low a temperature of the perfused liquid will not play a therapeutic role. Compared with systemic chemotherapy, the side effects are relatively small. However, this treatment needs to be operated by specialized physicians. It is recommended that patients go to regular hospitals for consultation and standardized treatment.
