The subcutaneous injection chamber technique is a valuable tool in the treatment of 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 placed under the skin of the chest wall to support intravenous drug and nutrition infusion without the risk of complications associated with peripheral veins. 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. By placing a subcutaneous injection chamber, patients can avoid these complications and improve their quality of life during treatment.
Patients who have had a subcutaneous injection chamber placed have reported increased convenience in their daily lives. The device allows for direct transmission of chemotherapy drugs to where they are needed without complications that may arise from peripheral vein administration. Additionally, it can be used for blood testing, fluid administration, and nutrition support for cancer patients who cannot consume orally. The procedure for placing a subcutaneous injection chamber involves inserting a catheter into a central vein either through the neck or below
