Identify your patient, introduce yourself Explain the procedure to the patient and
obtain a written informed consent, if possible.
Explain the indication, risks, benefits and alternatives.
Prepare the appropriate equipment Ask the patient to urinate before the
procedure to empty the bladder.
Before the procedure
![Page 7: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/7.jpg)
Position the patient in the bed with the head
elevated at 45-60 degrees, tilt the patient toward the site of paracentesis (allow fluid to accumulate in lower abdomen and air-filled loops of bowel tend to float to the other site, this will minimize trauma to bowel).
Ultrasound scan To identify the presence of encysted ascites To avoid distended bladder, small bowel
adhesions, large veins. How deep to insert the needle

The two recommended areas of abdominal wall entry for paracentesis are as follows:1. 2 cm below the
umbilicus in the midline
2. 5 cm superior and medial to the anterior superior iliac spines on either side
![Page 9: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/9.jpg)
Technique
Explain what is going on while performing the procedure, this will alleviate the patient's anxiety.
Wear sterile gloves Clean the area with
antiseptic solution in a circular fashion from the center out.
![Page 10: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/10.jpg)
Apply the sterile
drapes. You will place the opened parts of the kit on the drape.
Open the 16 G Angiocath and syringe place them on the sterile drapes. Place the 1-L vacuum bottles nearby.
Administer lidocaine at the insertion site
![Page 11: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/11.jpg)
Use scalpel blade to make a
small nick in the skin to allow an easier catheter passage
Insert the needle in Z-technique
Insert the needle directly perpendicular to the selected skin entry point. Slow insertion in increments of 5 mm is preferred to minimize the risk of inadvertent vascular entry or puncture of the small bowel.
![Page 12: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/12.jpg)
Continuously apply negative pressure to the syringe as the needle is advanced. Upon entry to the peritoneal cavity, loss of resistance is felt and ascitic fluid can be seen filling the syringe .
At this point, advance the device 2-5 mm into the peritoneal cavity to prevent misplacement during catheter advancement.
In general, avoid advancing the needle deeper than the safety mark that is present on most commercially available catheters or deeper than 1 cm beyond the depth at which ascitic fluid was noticed.
![Page 13: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/13.jpg)
Use one hand to firmly
anchor the needle and syringe securely in place to prevent the needle from entering further into the peritoneal cavity
Use the other hand to hold the stopcock and catheter and advance the catheter over the needle and into the peritoneal cavity all the way to the skin
![Page 14: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/14.jpg)
The self-sealing valve
prevents fluid leak. Attach the 60-mL syringe
to the 3-way stopcock and aspirate to obtain ascitic fluid and distribute it to the specimen vials and send it to the lab for analysis
![Page 15: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/15.jpg)
Connect one end of the fluid collection tubing to the stopcock and the other end to a vacuum bottle or a drainage bag
If the flow stops, kink or clasp the tubing to avert loss of suction, then break the seal and manipulate the catheter slightly, then reconnect and see if flow resumes.
![Page 16: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/16.jpg)
Post procedure
Remove the catheter after the desired amount of ascitic fluid has been drained.
Apply firm pressure Place sterile gauze a bandage
over the skin puncture site. Ask the patient to lie for 4 hours
and the nurse to check vital signs every hour for 4 hours to avoid hypotension.
Give 25 cc of albumin (25% solution) for every 2 liters of ascitic fluid removed.
![Page 17: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/17.jpg)

Place the patient in a
seated position, leaning slightly forward and resting the head on the arms or hands or on a pillow, which is placed on an adjustable bedside table.
This position facilitates access to the posterior axillary space, which is the most dependent part of the thorax.
![Page 26: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/26.jpg)
Technique
Explain what is going on while performing the procedure
After positioning ultrasonography is performed to confirm the pleural effusion, assess its size, look for loculations, determine the optimal puncture site and minimize complications
The optimal puncture site may be determined by searching for the largest pocket of fluid superficial to the lung
![Page 27: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/27.jpg)
Wash with antiseptic solution Placed sterile drape over the
puncture site The skin, subcutaneous tissue,
rib periosteum, intercostal muscles, and parietal pleura should be well infiltrated with anesthetic lidocaine
Use scalpel blade to make a small nick in the skin to allow an easier catheter passage
![Page 28: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/28.jpg)
The device is advanced over
the superior aspect of the rib while applying negative pressure until pleural fluid is obtained
The neurovascular bundle is located at the inferior border of the rib and should be avoided.
At 5 cm depth (mark on the device), the hemithorax is usually entered, and the needle don't need be advanced any further.

Connect the catheter
to syringe or vacuum bottle, the pleural effusion is drained until the desired volume has been removed for symptomatic relief or diagnostic analysis
![Page 31: Abdominal paracentesis - Geniuses - homemed1mcst.wikispaces.com/file/view/4. par… · PPT file · Web view · 2013-03-06After positioning ultrasonography is performed to confirm](https://reader031.vdocument.in/reader031/viewer/2022021818/5ab2ac0d7f8b9a00728d6701/html5/thumbnails/31.jpg)
Post procedure
Remove the catheter after the desired amount of pleural fluid has been drained.
Apply firm pressure and place sterile gauze and bandage over the skin puncture site
Position the patient on the unaffected side for 1 hour. This allows the pleural puncture to heal
Give analgesia Frequently check vital signs, oxygen saturation and
breath sounds to detect complications Send sample for analysis Write procedure note Request CXR to check for pneumothorax

Wash with antiseptic (if possible) The aspiration carried out in the second inter-costal
space in the mid-clavicular line just above the third rib (air accumulate in the upper chest unlike fluid).
Give local anesthesia with lignocaine. (if possible) Insert 16 G intravenous (IV) cannula On entry into the pleural cavity, a slight "pop" is often
felt and a gush of air will come out (hold the cannula tight)
Withdraw the needle and 3 way valve stopcock is inserted
A 50 cc syringe connected to the cannula Aspirate and expel the air with the needle

Note the amount of air aspirated. Aspirate until you feel resistance or if the patient
began to cough excessively Withdraw the cannula and seal the entry site Watch closely for signs of re-accumulation. If
this should occur and give rise to significant distress, a chest drain should be inserted and connected to an underwater seal.
Repeated aspiration will buy time until chest tube is inserted
Request CXR to assess efficiency of aspiration
