A subcutaneous injection chamber technique is utilized 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.
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, 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.
The device allows for direct transmission of chemotherapy drugs to where they are needed without complications from peripheral vein administration. Additionally, it can be used for blood testing, fluid administration, and nutrition support for cancer patients who cannot consume orally. Patients who have had a subcutaneous injection chamber placed have reported increased convenience in their daily lives as it eliminates need for multiple needles or catheters in different parts of their body.
The procedure for placing the subcutaneous injection chamber involves inserting a catheter into a central vein either through neck or below collarbone. The device is then placed under the skin in chest area and secured for stability using adhesive tape or stitches depending on its size and location. Patients may experience mild redness and pain at incision site but these symptoms typically subside within 24-48 hours after placement. It is important for patients to avoid heavy lifting and certain activities in days following placement procedure.
Overall, this technique has proven to be a valuable tool in reducing extravasation risks during chemotherapy while improving quality life for cancer patients by reducing discomfort associated with traditional methods such as intravenous lines that are prone to complications like clots or infection.
In conclusion, subcutaneous injection chambers provide an effective solution for cancer patients who require constant monitoring while receiving chemotherapy treatments without causing further harm or discomfort due to peripheral veins complications such as extravasation risks which could lead to severe burns on skin surface leading to further health problems like loss of mobility or even amputations
