PARACENTESIS 腹穿/腹腔穿刺术

4.                  Don sterile gown, gloves, and mask

5.                  Use skin prep solution to cleanse skin over the proposed puncture site, and drape to define a sterile field

6.                  Anesthetize the skin over the proposed puncture site with the lidocaine drawn up in the 5 cc syringe with the attached 25 gauge needle. Anesthetize down to the peritoneum. Aspirate periodically; if ascitic fluid returns, withdraw the needle slightly to re-enter tissue before further anesthetic is infiltrated

7.                  Attach 18 gauge needle  to free end of blood collection tubing or the secondary IV tubing. Leave capped. Close valve tightly on the tubing. Puncture the rubber stopper of the vacuum bottle with the other end of the tubing

8.                  Insert the 18 gauge needle perpendicularly through the anesthetized abdominal wall, and advance until hub of needle is 5mm-1cm from the skin surface. Open up the tubing clamp. Ascitic fluid should begin to flow into the bottle

9.                  9.   To change vacuum bottles as they become full, close the clamp on the tubing. Then, remove needle of collection tubing from the full bottle, and re-insert into empty bottle. Reopen clamp to start fluid flowing again

10.              When paracentesis is done, simply remove needle from abdominal wall. Place a small pressure dressing on puncture site. Have patient remain supine for 2-4 hours
