Introduction
Femoral deep venous catheterization is a commonly used clinical method for central venous access, serving to monitor central venous pressure and establish a route for medication administration. This procedure requires specialized skills and should be performed in a正规 hospital under the guidance of qualified physicians to minimize associated risks. It is also important to maintain healthy lifestyle habits in daily life.
Generally, femoral deep venous catheterization is a commonly used clinical method for central venous access, serving to monitor central venous pressure and establish a route for medication administration. The specific procedural steps are as follows:
1. Position the patient in a supine position and locate the puncture site, typically at the skin crease in the inguinal region where the femoral pulse can be palpated. The puncture point is located 0.5–1 cm medial to this pulsation.
2. Disinfect the skin at the intended puncture site, drape with a sterile fenestrated towel, and administer local anesthesia.
3. Gently press on the puncture site to stabilize the skin and vein locally.
4. Hold the puncture needle with the right hand and insert it through the skin, using the left hand's two fingers to fixate and guide the insertion site.
5. Advance the needle at an angle of 30–40 degrees while simultaneously aspirating with a syringe. Once blood return is observed, advance the needle an additional 3 mm.
6. Insert a guidewire through the hub of the needle, then remove the needle. Introduce a dilator over the guidewire to dilate the subcutaneous tissue.
7. Remove the dilator and insert the central venous catheter over the guidewire. Attach syringes to each lumen of a dual-lumen catheter, aspirate to confirm placement, and then flush with heparinized saline to maintain patency.
8. Suture and secure the catheter at the puncture site and cover it with sterile gauze.
This procedure requires professional expertise. It is recommended to undergo the procedure at a正规 medical facility under the guidance of a qualified physician to minimize risks. Additionally, maintain healthy lifestyle habits and avoid spicy or irritating foods that may impair recovery.
