I. What is abdominal chemotherapy The so-called abdominal chemotherapy is a treatment method to kill cancer cells by injecting chemotherapy drugs into the abdominal cavity within a specified period of time after the drugs have been configured in vitro according to the requirements, so that the drugs can directly interact with the residual cancer cells in the abdominal cavity. Commonly used drugs Fluorouracil, mitomycin, carboplatin, cisplatin, cyclophosphamide, bleomycin and so on. Fluorouracil is the most commonly used. III: Drug administration methods General laparotomy and laparotomy tube placement. They can be performed preoperatively, intraoperatively, and postoperatively. However, there are certain complications. 4. Steps 1: Routine blood tests and liver and kidney functions after admission. 2: The day before treatment, “hydration” treatment is performed, with 2000-3000 ml of fluid input, and 20 mg of intravenous furosemide injection is pushed before the end of infusion. 3：On the day of chemotherapy, infuse 1000–1500ml of fluid first, keep intravenous infusion usually, understand the characteristics of chemotherapy drugs, calculate the potency of chemotherapy drugs, ready to use, fully dissolved, pay attention to shade. 4: When cisplatin is injected intraperitoneally, sodium sulfate is infused intravenously to reduce nephrotoxicity. 5: artificial ascites and into the abdominal fluid temperature is higher than the body temperature of 2 degrees Celsius, can reduce the patient chemotherapy administration of abdominal discomfort and abdominal pain occurs. 6: artificial ascites: that is, the input of peritoneal fluid 1000 ml, the drip rate is greater than 150 drops / min. 7: After the infusion is finished, the patient should change the position every 15 minutes to ensure that the drug can be evenly distributed to the tumor surface to achieve the therapeutic effect. 8: Observe whether the patient has any adverse reactions. V. Timely treatment of complications and adverse reactions
