The subcutaneous injection chamber technique is used for cancer patients who are at risk of extravasation during chemotherapy. This technique helps to reduce the risk of skin necrosis and limit the side effects of the drugs being used. Dr. II Luu Kinh Khuong, Head of the Department of Anesthesiology and Resuscitation at Tam Anh General Hospital in Ho Chi Minh City, explained that chemotherapy drugs are typically administered through external intravenous lines, which can damage peripheral blood vessels and increase the risk of extravasation due to vein deviation. This method can also limit the patient’s movement in the limb where the infusion vein is placed.
The subcutaneous injection chamber is a device that is placed under the skin to support intravenous drug and nutrition infusion without the risk of complications associated with peripheral veins. It has proven to be a valuable tool in reducing the risk of extravasation during chemotherapy and improving the quality of life for cancer patients. Patients who have had this device placed have reported positive outcomes and increased convenience in their treatment process.
Extravasation due to chemotherapy is a common complication that can lead to irritation, ulcers, and skin necrosis. This is especially prevalent in elderly patients and those with weak vessel walls, obesity, edema, or skin lesions. To address this issue, healthcare providers place an implant under the skin that allows for direct transmission of chemotherapy drugs without damaging peripheral veins or increasing the risk of extravasation.
The procedure for placing the subcutaneous injection chamber involves inserting a catheter into a central vein either through the neck or below
