Abdominal paracentesis, also known as an abdominal tap or ascitic tap, is a medical procedure in which a needle is inserted into the abdominal cavity to remove excess fluid that has accumulated in the peritoneal space. This procedure is typically performed to diagnose the cause of abdominal fluid accumulation (ascites) or to provide symptomatic relief for patients with large amounts of fluid in their abdomen

1.
2. The accumulation of large amount of fluid within
the peritoneal cavity exerts pressure on the
diaphragm and abdominal organs and
vasculature, leading to respiratory compromise
and increased work of breathing. Paracentesis
relieves intra abdominal and diaphragmatic
pressures, diminishing the work of breathing.
3. “ Paracentesis is a procedure in which
fluid is removed from the peritoneal cavity for
diagnostic and therapeutic purposes.”
4. 1.To obtain fluid samples from the peritoneal
space for diagnostic examination.
2. Evacuate fluid from the peritoneal space.
3. Alleviate respiratory compromise related to
pressure on the diaphragm caused by ascetic
fluid.
5.
6. New onset ascites or ascites of
unknown origin.
Patient with a known ascites who has
fever, abdominal pain, hypotension or
encephalopathy.
Symptomatic treatment of large
ascites.
7. × Uncooperative patients
× Uncorrected bleeding diathesis
× Acute abdomen that requires surgery
× Intra-abdominal adhesions
× Distended bowel
× Abdominal wall cellulitis at the site of puncture
× Pregnancy
12. 1. Ultrasound scan before
the procedure
2. Patient preparation
3. Procedure
4. Laboratory results
13. What is the distance from the skin to
the fluid?
Usually 1 cm. It gives an idea how
deep you have to go with the needle
before getting fluid in the syringe.
14. Explain the rba (risks, benefits,
alternatives)
Informed written consent urinate before
the procedure or use a folley’s to empty
the bladder.
Position the patient in the bed with the
head elevated at 45-60 degrees to allow
fluid to accumulate in lower abdomen.
15. Position the patient in the bed with the head
elevated at 45-60 degrees
To allow fluid to
Accumulate
in lower abdomen.
16.
17. 2 cms below the umbilicus in the midline
(through the linea alba)
5 cms superior and medial to the anterior
superior iliac spines on either side.
18. Position the patient and prepare the skin
around the entry site with an antiseptic
solution .
20. 4-5 mL of lidocaine along the catheter
insertion tract,anesthetise
all the way down to the peritoneum.
21. Use the No. 11 scalpel blade to
make a small nick in the skin to
allow an easier catheter
passage.
22. Insert the needle directly
perpendicular to the
selected skin entry point.
Continuously apply negative
pressure to the syringe as
the needle is advanced.
Upon entry to the peritoneal
cavity, loss of resistance is felt
and ascitis fluid can be seen filling
the syringe.
23. Use one hand to firmly
anchor the needle and
syringe securely in place to
prevent the needle from entering
further the peritoneal cavity
Stabilization of needle
and syringe
24. While holding the stopcock, pull
the needle out.
Attach the 50-ml syringe to the
3-way stopcock and aspirate to
obtain ascitis fluid.
25.
26. Connect one end of the fluid
collection tubing to the stopcock
and the other end to a vacuum
bottle or a drainage bag .
