Oral and Systemic Health Link
Diabetes
Cardiovascular disease
Respiratory disease
Stroke
Premature birth
Mechanically Ventilated Patients
 Characteristics:
 Vulnerable to systemic infections due to disruption in
host defenses like mucociliary clearance, cytokine
production and salivary volume
 Dependent on healthcare providers to provide oral care
 Have the potential for bacterial load to be increased due
to lack of consistent oral care regimen
 Develop oropharyngeal colonization with pathogenic
organisms within the first 24 hours of intubation
Reasons for Lack of Oral Care Regimen
 Nurses receive little to no formal training
 Lack of priority, perceived need or time
 Patient’s inability to participate or request
 Medical conditions and equipment interfere
 Fear of endotracheal tube dislodgement
 Lack of published randomized controlled trials
examining the best practices for oral care in critically
ill patients
Complications of Poor Oral Hygiene
 Oropharyngeal colonization linked to the
development of ventilator-associated pneumonia
(VAP)
 Remains the most deadly hospital acquired infection in
intensive care units (8-15% estimated mortality rate)
 Increased dental plaque accumulation and oral
inflammation
 Disruption of tissue integrity
 Further complication of pre-existing oral conditions
Rationale for Good Oral Hygiene
 Oral care protocols (usually included in VAP bundles)
show decrease in incidence of VAP
 Oral care reflects preventive measures aimed at
reducing pathogenic organisms, and promoting
holistic patient care
 Patient comfort
 Prevention of halitosis
Although…to date
 No gold standard oral care protocol with optimal
frequency or products have been well established;
several organizations have published
recommendations to guide oral care of the
mechanically ventilated patient
 Institute for Healthcare Improvement (IHI)
 American Association of Critical-Care Nurses
(AACN)
 Centers for Disease Control and Prevention (CDC)
Institute for Healthcare Improvement
(IHI) Recommendation
 Daily oral care with 0.12% chlorhexidine
• Develop a comprehensive oral care process that includes
the use of 0.12% chlorhexidine oral rinse
• Schedule chlorhexidine as a medication, which then
provides a reminder for the RN and triggers oral care
process delivery
 Educate the RN staff about the rationale supporting
good oral hygiene and its potential benefit in reducing
ventilator-associated pneumonia
American Association of Critical-Care
Nurses (AACN) Recommendation
 Develop and implement a comprehensive oral hygiene
program for patients in critical care and acute care settings
who are at high risk for ventilator-associated pneumonia
(VAP)
 Brush teeth, gums and tongue at least twice a day using a soft
pediatric or adult toothbrush
 Provide oral moisturizing to oral mucosa and lips every 2 to 4
hours
 Use an oral chlorhexidine gluconate (0.12%) rinse twice a day
during the perioperative period for adult patients who
undergo cardiac surgery
 Routine use of oral chlorhexidine gluconate (0.12%) in other
populations is not recommended at this time
Centers for Disease Control and
Prevention(CDC) Recommendation
 Perform regular oral care with an
antiseptic solution
 The optimal frequency for oral care is
unresolved
Oral Care Protocol for Intubated
Patients
 Follow standard precautions and infection prevention
procedures including asepsis, gloves, a mask, and eye
protection (as needed)
 Obtain all necessary equipment prior to beginning
oral care
 Explain to the patient what you are planning to do so
they are not startled
 Note the position and placement of the endotracheal
tube prior to oral care
Assessment and Oral Cancer
Screening
 Assess all areas of the mouth for any signs of trauma,
inflammation, bleeding, ulcerations or suppuration
 Redness, swelling, exudate, tenderness and ulcerations
are signs of infections that should be further assessed to
rule out oral cancer.
Assessment
 Slight bleeding of the gums is common if
homecare has been deficient. With good
oral hygiene, bleeding will cease in a few
days of adequate care
 Xerostomia (dry mouth)
 Common in intubated patients
Assessment
 Assessment of the oral cavity should include all
surfaces of the mouth, carefully inspecting for
abnormalities.
 When inspecting the intubated patient be careful to
observe the position and placement of the
endotracheal tube.
Suctioning
 Prior to beginning the oral care protocol and
immediately following oral care it is
important to suction the patients mouth
and the subglottic space in order to prevent
aspiration of pooled secretions
 Suctioning should be repeated as needed
during oral care
Tooth Brushing
 The teeth and mouth should be cleaned at least twice a
day
 Use a soft bristle toothbrush with a small head
(pediatric size) for better access
 A smear of a sodium fluoride toothpaste
 Do not use a sodium monofluorophosphate fluoride if
chlorhexidine gluconate is to be used since the two are
not compatible
Tooth Brushing Technique
 Use a systematic sequence
 Angle the bristles toward the gumline and brush with
gentle pressure in small circular strokes on each tooth.
The bristles of the toothbrush will extend underneath
the gumline if adapted correctly
 Facial surfaces of all maxillary teeth, then linguals, then
repeat on the mandibular teeth. Brush the occlusal or
biting/chewing surfaces last with a scrub stroke
 Brush the tongue with long outward sweeping strokes
Gently move the tube from side to side as necessary for
access
Tooth Brushing
 Teeth should be brushed in a circular motion.
 Teeth of mechanically ventilated adults should be
brushed using the same technique with the exception
of the following modifications:
 observe the placement of the endotracheal tube by the
markings on the tube before and during oral care,
suction the oral cavity frequently and suction the
subglottic space following oral care to prevent
aspiration .
A mouth prop, tongue blade or bite block may be used to
hold the mouth open for unresponsive patients
Antiseptic/microbial application
 Antimicrobial
 Chlorhexidine gluconate (0.12%)

Recommended with little side effects (tooth staining)
 Swab the endotracheal tube as well to prevent bacterial
biofilm formation
 Swab twice a day with no rinsing afterward for a
minimum of 30 minutes
Moisturizing the Mouth
 Every two hours, moisturize the lips,
mucosa, tongue and corners of the mouth
with a water-based moisturizer
 Petroleum based products should be
avoided as they can dry tissues and are
harmful if aspirated
Detrimental Practices.
 Foam Swabs do not
remove plaque bacteria
as well as a toothbrush
and should not be
substituted
 Hydrogen peroxide is
acidic and can burn
soft tissues if not
diluted enough and
may also cause black
hairy tongue
 Lemon glycerin swabs are
very acidic and can cause
soft tissue burns and
decalcify the teeth
 Petroleum jelly dries out
oral tissues and can also
degrade latex gloves
Special Considerations
 Neuroscience patients
 Intracranial pressure
 Edentulous patients
 Brush the gums gently
 Facial trauma patients
 Modify tooth brushing
Role of Healthcare Providers
 Nurses
 Patient and other healthcare provider education
 Daily assessment of oral cavity
 Delivery and documentation of oral care
 Consultation as needed
 Respiratory Therapists
 Further assessment around endotracheal tube holders
 Maintenance of closed ventilation circuit
Role of Healthcare Providers
 Physicians/Nurse Practitioners/Physician Assistants
 Oral assessments
 Routine/standard order of antimicrobial rinse
 Collaboration with dental professionals
 Patient education
 Dental Hygienists/Dentists
 Referral follow-up
 Collaboration with critical care clinicians
