Peritoneocentesis
Laparocentesis
Abdominal paracentesis
The procedure used to remove fluid from
the peritoneal cavity.
Indications
✓Identifyetiology of ascites
✓To alleviate abdominal pressure or respiratory
distressin hemodynamicallystable patients.
✓To diagnosespontaneous bacterial peritonitis.
✓Diagnosemetastatic cancer.
✓To diagnosebloodinperitonealspace in case
of trauma.
PRE-Procedure
Patient Evaluation: General appearance,
vital signs.
The patient does not need to restrict
food or fluids.
Check patient history for hypersensitivity
to the local anesthetic
Empty bladder.
Explain the purpose, risks, benefits and steps
of the procedure.
Obtain informed consent from the patient or
appropriate legal designee.
Check platelet count and/or presence of
coagulopathy.
•.
Anesthetize the skin over the insertion site
With the catheter mounted to the syringe,
puncture the anesthetized skin.
Needle is inserted at a 45 degree angle or
with z tracking technique.
After the procedure, gently remove the
catheter, and apply direct pressure to the
wound.
Observe the characteristics of the fluid, and
send it for the appropriate studies. If the
insertion site is still leaking after 5 minutes of
direct pressure, suture the site.
Apply a pressure dressing.
For a therapeutic tap, do not remove more
than 500 ml in ten minutes.
One liter is the maximum that should be
removed at one time.
Removal of 5L or more than 5 is considered as
Large volume paracentesis.
Post Procedure
Observe patient for 30 minutes for
signs/symptoms of hypotension, bleeding, or
abdominal distress.
Provide post-procedural analgesics as needed.
Complications
i.Persistent leakage of asciticfluid at the needle
insertion site.
ii.Abdominal wall hematoma or bleeding
iii.Infection
iv.Perforation of surrounding vessels or viscera.
v.Hypotension after large volume fluid removal
(more than 5 L to 6 L).
vi.Electrolyte imbalance
Thoracentesis
Pleural fluid analysis, is a procedure in which a
needle is inserted through the back of the
chest wall into the pleural space to remove
fluid or air.
Purpose
❖For diagnostic purpose
To differentiate transudatefrom exudate
Pleural biopsy
❖As treatment procedure
To drain large amounts of pleural fluid
To equalize pressure on both sides of the thoracic cavity
Relieve shortness of breath and pain
Instillation of medication into the pleural space
Pre procedure
➢Consent
➢Assess for known allergies, especially to local
anesthetic.
➢If unable to sit, the patient should lie at the edge
of the bed on the affected side with the ipsilateral
arm over the head and the midaxillaryline
accessible for the insertion of the needle.
Elevating the head of the bed to 30 degrees
➢Instruct the patient to refrain from coughing,
breathing deeply or moving during the procedure
The usual site for insertion of the
thoracentesisneedle is the posterolateral
aspect of the back.
Mark the top of the dullness by washable ink
mark or indenting the skin.
Incision-below the fluid level.
Confirm site based on chest x-ray and
percussingout the fluid level.
Post procedure
•Sterile dressing is fixed in place.
•Obtain post-procedure chest x-ray results. The x-ray
verifies that there is no pneumothorax.
•Record total amount of fluid withdrawn, nature of fluid
its color and viscosity.
•A specimen container with formalin may be needed if
a pleural biopsy is to be obtained.
•Evaluate the patient at intervals for increased
respiration rate, asymmetric lung movement, vertigo,
tightness in the chest area, uncontrolled cough with
blood-tinged mucus, rapid pulse and signs of
hypoxemia.
Pericardiocentesis
Therapeutic and diagnostic procedure in
which fluid is removed from the pericardium,
the sac that surrounds the heart.
Removal of 5 –10 ml may increase stroke
volume by 25 –50%
Pericardial effusion v/sTamponade.
The acute or chronic accumulation of fluid in
the pericardial space (between the parietal
and the visceral pericardium) is pericardial
effusion
Cardiactamponade, also known as
pericardialtamponade, when fluid in the
pericardium builds up, resulting in
compression of the heart.
Causes
•Pericarditis
•Cytomegalovirus
•Coxsackieviruses
•Echoviruses
•HIV
•Cancer
•Injury to the sac or heart from a medical procedure
•Heart attack
•Severekidneyfailure, also called uremia
•Autoimmune diseases
•Bacterial infections, includingtuberculosis
Pre procedure
➢Prior to procedure: Use echocardiogram or
ultrasound to identify the fluid.
➢Patients who are receiving anticoagulants
should discontinue those medications prior to
the procedure.
➢Raise the blood pressure throughout the
procedure.
➢Procedure is done under imaging guidance.
➢Patient placed on supine position
➢The skin is sterilized and local anesthetic given
➢Use 3 inch, 16-20 gauge needle
➢The most standard location is through
theinfrasternalangle/subxiphoidapproach.
➢Another location is through the 5th or
6thintercostalspaceat the left sternalborder at
the cardiac notch also called as parasternal
approach.
Lumbar puncture/ Spinal tap
Procedure in which a needle is inserted into
thespinal canal to collectcerebrospinal
fluid(CSF) for diagnostic testing.
Indications

•Autoimmune conditions, such asmultiple sclerosisand
Guillain-Barresyndrome, can lead to an inflammatory
response, which can be detected by the presence of
autoantibodiesin the CSF.
•CSF analysis test to check for primary and metastatic
cancerous tumors in the CNS.
•DiagnoseAlzheimer's disease, by measuring levels of
amyloidbeta 1-42 (Aß1-42) and p-and t-tau proteins.
•In cases of infectious diseases meningitisandencephalitis,
CSF test can done to find out if the cause is viral, fungal,
bacterial, or due to a parasite, which will influence the
course of treatment.
•Intracranial bleeding
Arthrocentesis
Clinical procedure to collect synovial fluid
from a joint capsule.Itis also known as joint
aspiration.
When is ArthrocentesisPerformed?
❖Identification of the etiology of Arthritis.
❖Therapeutically for pain relief, drainage of
septic effusion
❖For Relieving pressure in the joint
❖Injection of medications
InGout
There is increased uric acid,monosodiumurate
crystals,monocytes.
Calcium pyrophosphate is present in chondrocalcinosis
(pseudogout).
Cholesterol crystals is common in RA
Synovial glucose level
Lowest in septic arthritis.
Glucose is also low in rheumatoid arthritis.
❖In bacterial arthritis, there is an increased level of
protein and lactate.

VENTRICULOPERITONEAL
SHUNTING
Ventriculoperitoneal(VP)shuntis a medical
device that relieves pressure on the brain
caused by fluid accumulation.VP shuntingis a
surgical procedure that primarily treats a
condition called hydrocephalus. This condition
occurs when excess cerebrospinal fluid (CSF)
collects in the brain's ventricles.
Different Kinds of Shunts
1.The abdomen (ventriculo-peritoneal or
lumbo-peritoneal shunt)
2.The lung (ventriculo-pleural shunt)
3.The heart (ventriculo-atrialshunt)
Ventriculoperitonealshunts consist of a valve
and two tubes, called catheters, which drain
the fluid.
One catheter drains fluid from the brain out of
a small hole . This is called the inflow catheter.
The other runs under the skin, taking the fluid
to a drainage site elsewhere in the body. This
is called the outflow catheter.
There are two types of ventriculoperitonealshunt
Programmable
Nonprogrammable
With a nonprogrammable shunt, the doctor
programs the valve so that it activates whenever
the fluid reaches a certain volume. It is not
possible to adjust a nonprogrammable shunt
after insertion.
A programmable shunt, however, has an external,
adjustable valve that the doctor can re adjust at
any time according to the person's needs.
•Positioning
The patients are kept supine with the head
rotated to the opposite side.
Procedure
•The surgeon makes a skin incision behind the ear. Another small surgical
cut is made in the belly.
•A small hole is drilled in the skull. One end of the catheter is passed into
a ventricle of the brain.
•A second catheter is placed under the skin behind the ear. It is sent down
the neck and chest, and usually into the belly area.
•A valve is placed underneath the skin, usually behind the ear. The valve
is connected to both catheters. When extra pressure builds up around
the brain, the valve opens, and excess fluid drains through the catheter
into the belly or chest area. This helps lower intracranial pressure.
Risks and complications may
include
oBlockage
oShunt malfunction
oOver-drainage
oUnder-drainage
oInfection
oDisconnection
HYDROCELE ASPIRATION
Accumulation of serous fluid around testicle.
It is often caused by fluid secreted from a
remnant piece of peritoneum wrapped
around the testicle, called tunica vaginalis.
COMPLICATIONS
a.Infertility
b.Pyocele
c.Fournier's gangrene
d.Scrotal calculi
e.Testicular ischemia
f.Calcification of the sac wall
g.Rupture of hydrocelesac
h.Hernia of the hydrocelesac in long standing
cases when tension of the fluid within tubica
causes herniationthrough dartosmuscle.
Procedure
Hydroceleis held tense by an assistant
Incision depending upon size is made over the most
prominent part of the swelling parallel to the median
rapheof the scrotum.
Layers opened :skin, dartos, external spermatic fascia ,
cremastericfascia , internal spermatic fascia.
At this stage hydrocelesac is visible and is delivered
outside the incision
Hydrocelefluid is drained by using trocarand cannula
Post –operative management
Antibiotics and analgesics
Suture removal after 7-8 days

❑First fomented and then a piece of cloth should
be tightened.
❑A puncture should then be made in the bottom
of the sac with a Vrihimukhainstrument, on
either side of the Sevani.
❑A tube open at both ends should be introduced
and the accumulated fluid should be let out. The
tube should then be taken off and the scrotum
should be tied up with a bandage(Sthagika) and
the incidental ulcer should be healed.
