The subcutaneous injection chamber technique is a valuable tool for cancer patients at risk of extravasation during chemotherapy. It helps to reduce the risk of skin necrosis and limit the side effects of the drugs being used. According to Dr. II Luu Kinh Khuong, Head of the Department of Anesthesiology and Resuscitation at Tam Anh General Hospital in Ho Chi Minh City, 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 also limits the patient’s movement in the limb where the infusion vein is placed.
Extravasation due to chemotherapy is a common complication that can lead to irritation, ulcers, and skin necrosis. It is especially prevalent in elderly patients and those with weak vessel walls, obesity, edema, or skin lesions. To address this issue, a 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.
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 arising 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 the subcutaneous injection chamber involves inserting a catheter into a central vein either through the neck or below the collarbone. The device is then placed under the skin in the chest area and secured for stability. Patients may experience mild redness and pain at the incision site but these symptoms typically subside within 24-48 hours. It’s important that patients avoid heavy lifting and certain activities in
