Furuncle drainage surgery process

When you have boils on your body, if they are serious and cannot be cured by medication, the best way is drainage surgery. The occurrence of furuncle is related to bacterial infection. It will grow larger and become purulent. The surgical procedure for furuncle drainage is not complicated. Generally, an opening is made from the side of the abscess, and the skin is cut layer by layer to drain the pus. The operation is relatively short, but postoperative care is very important.

Preoperative preparation

1. Use antibiotics rationally. 2. For those with general weakness, systemic supportive treatment should be strengthened.

anaesthetization

1. Local infiltration anesthesia.

2. Brachial plexus block anesthesia (upper limbs) or spinal anesthesia (lower limbs).

3. General anesthesia: intravenous anesthesia with sodium thiopental or inhalation anesthesia such as halothane, enflurane, ether, etc.

4. Children can be anesthetized by intramuscular injection of ketamine, supplemented with local anesthesia or nerve block anesthesia.

Surgical procedures

Take the deep medial femoral abscess as an example.

1. Incision

Disinfect the skin with iodine tincture and alcohol and cover it with sterile towels. After local puncture and extraction of pus, the needle is left in place. The direction of the incision should be based on the location of the abscess and parallel to the femoral artery, vein, femoral nerve or other major blood vessels and nerves to avoid injury.

2. Separate the muscle layer and cut open the abscess

After cutting the skin and subcutaneous tissue, be careful to avoid the great saphenous vein, femoral vein and femoral artery or other major blood vessels and nerves, and separate along the needle direction to find the site of the abscess deep in the muscle layer. Make a small longitudinal incision on the abscess wall and use hemostatic forceps to enter the abscess cavity to drain the cavity fluid. Then insert your fingers into the abscess cavity and separate the fibrous septa. The incision in the abscess wall was then enlarged to ensure smooth drainage1.

3. Place drainage strip

Place Vaseline gauze strips or cigarette drains depending on the size and depth of the abscess. If there is active bleeding, it can be clamped with hemostatic forceps and then ligated; generally, small oozing blood can be blocked with Vaseline gauze and the bleeding can be stopped after applying pressure bandage.

Postoperative precautions

1. The direction of the incision for deep abscesses should be parallel to the course of arteries, veins, and nerves to avoid injury.

2. Before opening a deep abscess, pay attention to the anatomical relationship of adjacent important tissues - especially nerves and blood vessels, and avoid damaging them. For example, for a deep abscess on the medial femoral side, attention should be paid to the femoral artery, vein and femoral nerve; for a popliteal abscess, attention should be paid to the popliteal artery, vein and tibial nerve; for an axillary abscess, attention should be paid to the axillary artery, vein and brachial plexus.

Postoperative care

On the second day after surgery, the dressing was changed and the abscess cavity was loosened for drainage. During each subsequent dressing change, the drainage strip should be gradually removed as the pus decreases, and the removal site should be cut off until it is completely removed.
