Introduction
Paracentesis with catheter placement is primarily used to drain ascites and prevent excessive intra-abdominal pressure. It is currently one of the common methods for relieving abdominal pressure and requires a high level of expertise. The procedure should be performed under the guidance of a qualified physician to avoid causing bodily harm. Regular follow-up abdominal ultrasound examinations are recommended to monitor changes in ascites.
Generally, abdominal paracentesis catheterization is commonly performed to drain ascites and prevent excessive intra-abdominal pressure. It is currently one of the frequently used methods to relieve abdominal pressure. The specific procedure is as follows:
1. Use color ultrasound to locate the precise puncture site, then routinely disinfect the surrounding skin with iodophor or medical alcohol.
2. Drape a sterile fenestrated towel and perform local infiltration anesthesia on the skin near the puncture site.
3. Make a 2mm incision at the puncture site and insert the puncture needle; ascites should be visible upon aspiration.
4. Gently advance the guidewire through the puncture needle into the abdominal cavity, taking care to avoid injury to the bowel.
5. Remove the puncture needle and use a dilator to enlarge the skin incision. After dilation, insert the catheter over the guidewire into the abdominal cavity, typically advancing it 10–12 cm.
6. Secure the catheter, remove the guidewire, and connect the external end of the catheter to a drainage bag to complete the procedure.
This procedure is highly specialized and must be performed by a qualified physician under strict aseptic conditions to prevent bodily harm. Regular follow-up abdominal ultrasound examinations are recommended to monitor changes in ascites.
