What is an intraperitoneal catheter?
Intraperitoneal (IP) catheter is a catheter that is surgically inserted into the stomach cavity for drug release, usually chemotherapeutic drugs. Unlike the widely used intravenous (IV) catheters that remain outside the body, the intraperitoneal catheter is completely closed inside the body, allowing the drug to enter the bloodstream through the stomach wall. With this catheter placing, the drug can enter the body faster and at higher concentrations than when it is supplied through the veins. Also, medicine supplied by intraperitoneally remains active in the body longer, and therefore has a greater therapeutic impact.
Made of tubes consisting mainly of silicone, rubber or polyurethane, the intraperitoneal catheter must be connected to the inner membrane of the stomach for the transmission of liquid medicines and salt solution to Coel. The cuffs and discs anchor the intraperitoneal catheter to ensure that it does not move inside the abdominal, because migration can cause tears or leaks, which can lead to infection. Doctors canTime to use a special two-tube that includes extperitoneal hoses and intraperitoneal tubing.
While no severe pain is associated with the delivery of the drug via an intraperitoneal catheter, patients may feel abdominal discomfort if too much solution flows into the stomach. Usually, 33 oz (1 l) to 63 oz (2l) of the saline mixed with medicine are sent to the body. When the drug is absorbed into the stomach membrane for 24 hours, patients are regularly rotated by position to allow the drug to contact the most surface surfaces of the stomach internal lining. In days after intraperitoneal chemotherapy, patients could feel nausea, stomach cramps or lethargy. The risks associated with the use of the intraperitoneal catheter include peritonitis, which is an inflammation of the stomach lining and its cavity.
Scientific studies confirm that medicines for chemotherapy such as paclitaxelAnd cisplastin, it was found to be much more effective when they are delivered by an intraperitoneal catheter. Cancer treatment using an intraperitoneal catheter is most effective for the malignancy of organs in the center of the body, such as ovarian cancer or organs in the gastrointestinal tract. Medical studies suggest that patients with cancer treated with chemotherapy through IP catheter may have longer remission and life expectancy. On average, these patients live a year and a half longer than patients who receive chemotherapy intravenously, suggest studies.
It is rarely used as a treatment of cancer, chemotherapy by intraperitoneal catheter is usually monitoring the excision of surgical tumor. Catheter delivery may be repeated for several days, depending on the severity of malignancy. Some patients may need two consecutive days of the top -up management days, while others receive several days for two or three weeks. In addition to chemotherapy, an intraperitoneal catheter can be used for dialysis.
