2. INTRODUCT
ION
• Suction can be used to
remove secretions from
intubated patients and
from infants and children
who are unable to cough
and expectorate.
3. GENERAL
PRINCIPLES
• The technique should be as quick, clean and gentle as
possible.
• Suction is very traumatic to delicate mucosal tissue and it is
very easy to introduce infection, especially in intubated
patients.
• Suction should only be carried out as and when necessary,
rather than on a routine basis.
4. SUCTION
TROLLEY:
• All the equipment needed for airway suction should be set
out on a trolley for ease of access:
1. Sterile plastic gloves - disposable.
2. Suction catheters - appropriate sizes for the
patient.
3. Lubricating jelly water-based only, not oil-based, for
use in nasopharyngeal
suction.
4. Sterile gauze swabs - to transfer jelly to tip of
catheter.
5. sterile water - to flush the secretions through the
catheter and tubing. Sodium bicarbonate acts as a
solvent of the secretions.
6. Forceps (if used).
7. Plastic bag for the collection of disposables
5. INDICAT
ION
1. Whenever secretions can be heard in an intubated patient.
2. For retained secretions in the spontaneously breathing
patient who is unable to cough and expectorate efficiently.
3. Before and during the release of the cuff on a
tracheostomy tube.
4. If the inflation pressure of the ventilator suddenly' rises.
This may indicate the
presence of a large plug of mucus in one of the larger
bronchi or even within the
endotracheal or tracheostomy tube.
5. If the minute volume (MV) drops, this may indicate
retained secretions
6. RISKS AND
COMPLICATIONS OF
1. Trauma:
• Mucosal haemorrhage and erosion frequently occur in the
patient who has been suctioned, leading eventually to the
formation of granulation tissue.
• The amount of trauma depends upon the frequency of
suction, the amount of negative pressure applied, the
size and type of catheter used and the vigour of insertion.
7. 2.
Hypoxi
a.
• This can occur following suction.
• To avoid this the suctioning time should be kept to a
minimum, particularly in tl](ose patients who are dependent
on a ventilator, and the inspired oxygen and/or ventilation
may be increased prior to suction providing there are no
contra- indications.
8. • Cardiovascular effects.
• Cardiac arrhythmias and hypotension can occur during
suction due to hypoxia and/or vagal stimulation from
direct pharyngeal and tracheal irritation.
• Particular care should be taken with neonates as bradycardia
and apnoea can follow nasopharyngeal suction in these
patients
9. •Atelectasis.
• Too large a suction catheter in too small an airway will
prevent room air from
entering around the catheter during suctioning and
atelectasis, in varying degrees,
may occur.
• Too high a negative suction pressure may also cause
atelectasis and airway collapse.
10. •Pneumothorax.
• This can occur primarily in premature infants with severe
underlying lung disease due to perforation of segmental
bronchi by a suction catheter
11. TYPES
Depending on site of
Suctioning
A. Nasotracheal suctioning
(NT)
B. Oropharyngeal suctioning
C. Tracheostomy suctioning
(TT)
D. Endotracheal suctioning
12. PROCEDURE:-
SUCTION FOR
INTUBATED
PATIENTS
1. Wash
hands.
prepare saline or mucolytic solution - prepare
gloves/forceps.
2. Prepare equipment: - turn on vacuum, check pressure -
attach suction catheter -
3. Prepare patient - if conscious the patient should be
swaddled in a blanket being
aware of infusions, drains, tubes, etc; or he should be held
firmly by an assistant.
The procedure should be explained to the child and
constant reassurance given while suctioning is taking place
4. Physiotherapy may be carried out at this
point if indicated.
13. 5. Place glove on the hand that is to hold suction catheter.
6. Withdraw catheter from its sterile pack with the gloved
hand.
7. Disconnect ventilated patient from ventilator.
8. Insert catherter into tube without applying suction.
9. Push catheter gently and quickly down tube until a slight
resistance is met.
10. Withdraw catheter 0.5cm.
11. Apply suction.
12. Withdraw catheter quickly, rotating gently between
thumb and first finger and
interrupting the suction pressure every few seconds.
14. 13. Reconnect patient to ventilator.
14. The same catheter can then be used to clear secretions from
the mouth and nose.
15. Discard both the glove and the catheter.
16. Repeat until secretions are cleared.
15. SUCTION FOR NON-INTUBATED PATIENTS
• Children and infants should always be suctioned in side lying to prevent
aspiration of vomit.
1. Wash hands.
2.Prepare equipment: - turn on vacuum, check pressure - attach suction
catheter - prepare saline or mucolytic solution - prepare gloves/forceps.
3. Prepare patient - if conscious the patient should be swaddled in a
blanket being
aware of infusions, drains, tubes, etc; or he should be held firmly by an
assistant. The procedure should be explained to the child and constant
reassurance given while
suctioning is taking place.
4. Physiotherapy may be carried out at this point if indicated.
5. Place glove on the hand that is to hold suction catheter.
6. Withdraw catheter from its sterile pack with the gloved hand
16. 7. Gently insert catheter into the nose using an upward
motion until the nasal septum is passed, then using a
downward motion. If a slight resistance is met, withdraw
catheter slighdy and try again.
8. Insert catheter to the back of the throat until a cough has
been stimulated. It is possible to pass a catheter into the
trachea by inserting the catheter during inspiration, but
an effective cough can be elicited merely by stimulating
the pharynx.
9. Apply suction.
10. Withdraw catheter, rotating slightly between thumb
and first finger and
interrupting the suction every few seconds.
11. Repeat procedure via other nostril.
12. Discard both the glove and the catheter.
13. Repeat until secretions are cleared.
17. ORAL SUCTION
Ensure that the catheter is not curling up in the
mouth.
9.Apply suction.
10.Withdraw catheter.
11.Repeat until secretions are clear.
12.Discard both the glove and the cathete
8. Pass suction catheter to the back of the throat until a cough
has been stimulated.
18. CLOSED-CIRCUIT
SUCTION
• Closed-circuit suction
systems are available and
consist of a catheter in a
protective closed sheath
which remains attached to
the endotracheal or
tracheostomy tube for 24
hours.
• The indications for use are:
immuno- suppressed
patients, actively infectious
patients (e.g. open TB) and
patients with severe
refractory hypoxaemia on
high levels of PEEP.
19.
20. PRECAUTIONS
1. 100 — i20mmHg is ideal for most patients although
pressure up to —200mmHg may be needed for thick
secretions.
2. Nasopharyngeal suction:
I. When introducing a suction catheter via the nose it is
helpful if the patient’s neck is extended so that the head is
tilted backwards resting on a pillow. If the patient can co-
operate the tongue should be protruded, as this helps when
attempting to pass the catheter between the vocal cords
and into the trachea
II. It must be remembered that nasopharyngeal suction is a
very unpleasant experience for the conscious patient
and should only be used when absolutely necessary.
III. Nasopharyngeal suction should not be used for patients
with head injuries where there is a leak of CSF into the
nasal passages.
21. 3. Oropharyngeal suction.
I. A lubricated plastic airway is usually tie eded to prevent the patient
biting the catheter and it is difficult to direct the catheter accurately
into the pharynx and beyond.
4. Suction via tube
I. Whatever the mode of entry, the physiotherapist must ensure
that no suction
pressure is applied while the catheter is being introduced.
II. If, during nasopharyngeal suction, the patient becomes
cyanosed I and the catheter was difficult to insert, it is
acceptable to disconnect the suction, leaving the catheter in
situ, while administering oxygen J until the patient recovers
and suction can be resumed.
III. No longer than 15 seconds should elapse between the
disconnec - I tion and reconnection of the patient to the
ventilator, more than adequate time for effective removal of
secretions by the experienced I operator. j Where possible, the
patient should be suctioned in side lying or 1 with the head
rotated to one side to avoid aspiration of gastric
contents should vomiting occur.
22. STEPS
including RR or adventitious sounds, nasal
secretions, drooling, gastric secretions, or
vomitus in mouth
• Rationale
• Physical signs and symptoms result from pooling
of secretions in upper and lower airways.
1. Assign signs and symptoms of upper and
lower airway
obstruction
nasotracheal or orotracheal
requiring
suctioning,
23. Assess signs and symptoms associated with hypoxia and
hypercapnia.
• Rationale
• Physical signs and symptoms resulting from
decreased oxygen to tissues indicate need for
suctioning.
Step 2
24. Step
3
• Determine factors that normally
influence upper or lower airway
functioning
• Fluid Status
• Lack of Humidity
• Infection
• Anatomy
• Rationale
• Fluid overload may increase
amount of secretions. Dehydration
promotes thicker secretions
• The environment influences
secretion formation and gas
exchange, necessitation airway
suctioning when cannot clear
secretions effectively.
• Clients with respiratory infections
are prone to increased secretions
that are thicker and sometimes
more difficult to expectorate
• Abnormal anatomy can impair
normal drainage or secretions.
25. Step
4
• Assess client’s understanding of procedure
(when applicable)
• Rationale:
• Reveals need for client instruction and also
encourages cooperation.
Step 5
• Obtain physicians order if indicated by agency policy.
●
Rationale
●
Some institutions require a physicians order for
tracheal suctioning
26. Step 6
• Help client assume position comfortable for nurse and client
(usually semi-Fowler’s or sitting upright with head
hyperextended, unless contraindicated).
• Rationale
• Reduces stimulation of gag reflex, promotes client
comfort and secretion drainage, and prevents
aspiration.
• Lessens strain on nurses’ back.
• Hyperextension fascilitates insertion of catheter into
trachea.
27. Step
7
• Place pulse oximeter on client’s finger.
Take reading and leave pulse oximeter in
place.
• Rationale
• Provides baseline SpO2 to determine
client’s response to suctioning.
Step 8
• Place tower across client’s chest.
●
Rationale
● Reduces transmission of
microorganisms by protecting gown
from secretions.
28. Step
9
• Perform hand hygiene.
• Rationale
• Reduces transmission of
microorganisms.
29. Step
10
Preparation for all types
of suctioning
• Open suction kit or
catheter with use of
aseptic technique. Do not
allow the suction catheter
to touch any unsterile
surfaces.
• Unwrap or open sterile
basin and place on
bedside table. Fill basin
with approx 100ml of
sterile normal saline
solution or water.
Rationale
• Prepares catheter and
prevents transmission of
microorganisms.
30. Step 10 continued…
Preparation for all types
of suctioning
• Connect one end of
connecting tubing to
suction machine. Place
other end in convenient
location near client.
Check that equipment is
functioning properly by
suctioning a small
amount of water from
basin.
Rationale
• Equipment must be in
proper working order to
prevent delay in the
procedure.
31. Step 10 continued…
Preparation for all types
of suctioning
• Turn on suction device.
Set regulator to
appropriate negative
pressure: wall suction, 80
– 120mmHg; portable
suction, 7 – 15 mmHg for
adults.
Rationale
• Elevated pressure
settings increase risk of
trauma to mucosa and
can induce greater
hypoxia.
32. Step 11 – Oropharyngeal Suctioning
Consider applying mask
or face shield.
Attach suction catheter
to connecting tube.
Remove oxygen mask if
present.
Insert catheter into
client’s mouth.With
suction applied, move
catheter around mouth,
including pharynx and
gum line, until
•
• Apply clean disposable •
glove to dominant hand.
Suction of oral cavity
does not require sterile
glove use.
• Suction may cause
splashing of body fluids.
• If catheter does not have
a suction ctrl, apply
intermittent suction, take
care not to allow suction
tip to invaginate oral
mucosal surfaces with
continuous suction.
33. Step 11 – Oropharyngeal Suctioning cont’d…
•
• Encourage client to
cough, and repeat
suctioning if needed.
Replace oxygen mask if
used
Suction water from basin
through catheter until
clear from secretions
• Place catheter in a clean
dry area for reuse with
suction turned off or
within client’s reach, with
suction on, if client is
capable of suctioning self.
• Coughing moves
secretions from lower to
upper airways into the
mouth.
• Clearing secretions before
they dry reduces probability of
transmission of
microorganisms and enhances
delivery of preset suction
pressures.
• Facilitates prompt
removal of secretions
when needed in the
future.
34. Nasopharyngeal
Suctioning
• If indicated, increase
supplemental oxygen
therapy to 100% or as
ordered by physician.
Encourage client’s deep
breathing.
• Preoxygenation and deep
breathing assist in reducing
suction-induced hypoxemia.
Preoxygenation should be
used with caution in oxygen
sensitive clients such as
those with chronic heart and
lung conditions and those
with pneumonia.
35. Nasopharyngeal Suctioning…
• Open lubricant. Squeeze
small amount onto open
sterile catheter package
without touching package.
• Apply sterile glove to each
hand
• Prepares lubricant while
maintaining sterility. Water
soluble lubricant is used to
avoid lipoid aspiration
pneumonia. Excessive
lubricant can occlude
catheter.
• Reduces transmission of
microorganisms and allows
nurse to maintain sterility of
suction catheter.
36. Nasopharyngeal Suctioning…
• Pickup suction catheter
with dominant hand without
touching nonsterile
surfaces. Pick up
connecting tubing with
nondominant hand. Secure
catheter to tubing.
• Lightly coat distal 6 to 8 cm
(2-3in) of catheter with
water-soluble lubricant.
• Maintains catheter sterility.
Connects catheter to
suction.
• Lubricates catheter for
easier insertion.
37. Nasopharyngeal Suctioning…
• Measure the distance from
the tip of the nose to the tip
of the earlobe 13 cm (5in)
• Follow natural course of
naris; slightly slant catheter
downward and advance to
back of pharynx.
• When pulling back the
catheter, slightly roll the
tube between the thumb
and index finger.
• Proper placement ensures
removal of pharyngeal
secretions.
• Rolling the tube back and
forth ensures suctioning in
all areas.
38. Nasopharyngeal Suctioning…
•
• Encourage client to cough.
• Allow for rest periods and
repeat this procedure until
airway is cleared. Limit
suction time to 3-5 mins.
Reapply oxygen as
needed.
• Coughing facilitates
removal of secretions
• Rest periods allow for rest
and reoxygenation
• Repeated passes with the
suction catheter assist in
clearing the airway of
excessive secretions and
promotes oxygenation.
39. Nasopharyngeal Suctioning…
• Rinse catheter and
connecting tubing with
normal saline or water until
cleared.
• Reassess client’s
respiratory status.
• Clearing secretions before
they dry reduces probability
of transmission of
microorganisms and
enhances delivery of preset
suction pressures.
