INDICATIONS OF
INTUBATION
Cardiopulmonary Arrest
 Patient in coma
 Tachpnea/ Bradypnea
 Progressive cyanosis
 Surgical patients
 Airway protection from any cause

ADVANTAGES

 Prevents aspiration of secretions into the
lungs
 Facilitates positive pressure ventilation
without gastric inflation
 Facilitates body positioning and movement
 May be utilized to deliver medication
 Narcan
 Atropine

 Lidocaine

DISADVANTAGES

the procedure
 Bypasses function of the nose to warm and
filter the inspired air
 Increased incidence of trauma due to neck
manipulation when spinal cord injury is
suspected
 May increase respiratory resistance
 Improper placement



ENDOTRACHEAL TUBES
Types of endotracheal tube (ETT)
include oral or nasal, cuffed or uncuffed, preformed (eg RAE tube),
reinforced tubes, double-lumen tubes
and tracheostomy tubes. For human
use, tubes range in size from 2-10.5 mm
in internal diameter (ID).

Endotracheal tubes are made from red rubber
and Polyvinylchloride. Those placed in a laser
field may be flexometallic.
REINFORCED ETT
Indications For Usage
 Patient's head is in extended
or flexed position
 Patient will be turned over
 Long-term cases
 Neurosurgical procedures
 Head and neck procedures
NASAL AND ORAL RAE
 NASAL
RAE TUBES II
Preformed Endotracheal Tubes are designed
to conveniently position the anesthesia circuit
out of the surgical field for oral and
maxillofacial procedures.
 Oral Preformed shape directs tube downward,
to rest on patients chin
 Cuffed tubes available with Murphy Eye only
 Uncuffed tubes have two Murphy Eyes for
enhanced patient safety
 Bold marks at the center of bend with
distance to distal tip indicated

Tracheal Tube Cuff
Care
These include bedside sphygmomanometers,
special aneroid cuff manometers, and
electronic cuff pressure devices.
 Ideally, most tubes seal at pressures between
14 and 20 mm Hg (19 to 27 cm H2O).
 Tracheal capillary pressure lies between 20
and 30 mm Hg
 Impairment in tracheal blood flow seen at 22
mm Hg and total obstruction seen at 37 mm
Hg

Sphygmomanometers
High Volume Low
Pressure Tubes
Minimum Leak Volume
Technique
Air inflation of the tube cuff until the airflow
heard escaping around the cuff during
positive pressure breath ceases.
 Place a stethoscope over larynx. Indirectly
assesses inflation of cuff.
 Slowly withdraw air (in 0.1-mL increments)
until a small leak is heard on inspiration.
 Remove syringe tip, check inflation of pilot
balloon

SECRETION CLEARANCE
OPEN SUCTION SYSTEM
 Made of non-toxic PVC
 Available coded for size identification Closed
suction systems
CLOSED SUCTION SYSTEM
 (CSS) are increasingly replacing open suction
systems (OSS) to perform endotracheal toilet
in mechanically ventilated intensive care unit
patients.
Endotracheal or Tracheostomy
Tube Suctioning
Open Suctioning
Disconnection from the
ventilator
Not recommended when
PEEP >10
Closed Suctioning:
Facilitate
continuous
mechanical ventilation and
oxygenation during the
suctioning.
Indicated when PEEP level
above 10cmH2O
Open Suctioning Technique
Closed Suctioning Technique
ETT WITH EVACUATION
LUMEN
INDICATIONS
For airway management by
oral/nasal intubation of the
trachea and for evacuation
or drainage of secretion from
the subglottic space
ADVANTAGES OF EVAC
Helps decrease the rate of ventilatorassociated pneumonia (VAP) in the hospital
and to reduce VAP related costs
 Convenient and safe method for suctioning
accumulated secretions in the subglottic
space
 Large elliptical evacuation port located on
dorsal side proximal to cuff provides effective
evacuation
 Integral suction lumen allows continuous
suctioning without risking trauma to the vocal
cords as with manual catheter suctioning

ETT CARE
Use of Gause @ the angles of mouth to
prevent damage to mucosa
 Moving ETT Q NOC from one to the other
side to avoid damage to mucosa
 Monitoring the correct position of ETT@ the
lip mark and positioning it properly
 Monitoring the ETT position on CXR from time
to time
 Regular suctioning through ETT

DIFFICULT AIRWAY
LET US SEE…
What is a difficult airway ?
 The importance of difficult airway cart.
 Different modalities to be used in difficult
airways situations.
 Anticipate Difficult Airway.
 Be Prepared and have many back up plans.

WHAT IS A DIFFICULT
AIRWAY
According to American Association of
Anesthesiologist, it is a clinical situation in
which a trained anesthesiologist experiences
difficulty with mask ventilation, tracheal
intubation or both.
 Requires more than 3 attempts or 10 min. to
intubate.
 Grade lll to lV in both Cormack and
Mallampadi Classifications.

PRE-INTUBATION
EVALUATION
Potentially difficult laryngoscopy includes:

Poorly visualized uvula.
Short, thick neck.
Receding mandible and protruding teeth.

INTUBATING STYLET
A stylet for intubating an endotracheal tube is
like medico-surgical tube comprising of a
bendable metal rod sealed in a tubular plastic
sheath. The ends of the sheath are molded in
a smoothly rounded closed shape.
 Passed through an ETT, can be bend to give
ETT the shape of a hockey stick.

.
STYLET
ADVANTAGES
Alow intubation of the trachea with minimal
visualization of the vocal cords.
 Easy to learn.
 Helps in stablizing the ETT for intubation

DISADVANTAGES

May be incorrectly inserted and can damage
tracheal tissues.

LMA

The Laryngeal Mask Airway is an
alternative airway device used for
anesthesia and airway support. It consists
of an inflatable silicone mask and rubber
connecting tube. It is inserted blindly into
the pharynx, forming a low-pressure seal
around the laryngeal inlet and permitting
gentle positive pressure ventilation. All
parts are latex-free.
LARYNGEAL MASK AIRWAY
LMA
INDICATIONS
The Laryngeal Mask Airway is an
appropriate airway for short procedures
and in emergency situations.
 Can be used as rescue airway and
fiberoptic conduit when intubation is
difficult.
 Can be used for bronchoscopy in awake
patients.

LMA
CONTRAINDICATIONS
Non-fasted patients
 Morbidly obese patients
 Pregnancy
 Obstructive or abnormal lesions of the
oropharynx
 Increased Airway resistance and decreased
lung compliance

Tips for Success:
Begin with ASA I & II patients
 Learn and use standard insertion technique
 Use appropriate size and do NOT overinflate
 Maintain adequate anesthetic depth
 Remove when the patient opens mouth to
command

COMBITUBE
Consists of two fused tubes with a 15 mm
connector at proximal end.
 Contains 2 cuffs, 100 cc proximal and 15 cc
distal.
 Distal lumen usually lies in esophagus so
the gas through blue tube will ventilate
Trachea.
 If Combitube enters trachea, ventilation is
through clear tube. Available in only one
disposable size for age> 15 years , height
>5ft.

COMBITUBE
COMBITUBE II
BOUGIE
A semi-rigid stylette-like device with bent tip
that can be used when intubation is
difficult. During laryngoscopy the
bougie is carefully advanced into
the larynx and through the cords
until the tip enters a mainstem
broncus. While maintaining the
laryngoscope and Bougie in position,
an assistant threads an ETT over the
end of the bougie, into the larynx.
Once the ETT is in place,
the bougie is removed.

ETT EXCHANGER
Facilitates quick, efficient endotracheal tube
exchange or replacement without using a
laryngoscope
 Flexible material, frosted surface and depth
marks aid precise placement and minimize
drag
 Internal lumen allows for spontaneous
breathing during tube exchange
 Longer size allows exchange of the ETT
while exchanger is still in the trachea
 These devices allow insufflation of O2 and jet
ventilation.

ETT EXCHNAGER
ADVANTAGES
 Relatively short learning time
 Allow changing endotracheal tube with
guide still in the trachea e.g. in case of
ruptured ETT cuff
DISADVANTAGE
 Improper placement of ETT may still occur
with these devices if guide is not placed
completely in the trachea
CRICOTHYROTOMY

Kits that allow introduction of some type of
tube into the trachea via cricothyrotomy .Most
of the kits are designed as temporary airway
and need to be replaced by a tracheostomy
tube after establishment of ventilation and
stabilization of patient
CRICOTHYROTOMY KIT
ADVANTAGES
 Rapid access to subglottic
area
Does not require visualization
of the larynx.
FLEXIBLE FIBEROPTIC
BRONCHOSCOPE
The fibreoptic bronchoscope is constructed of
fibreoptic bundles and cables encased in a
slender, waterproof sheath from the handle to
the tip.
 The cable system permits manipulation of the
tip of the bronchoscope by adjustments @the
handle, the operating end of the device.
 Excellent visualization of the airway with
minimal homodynamic stress when properly
performed.

FIBEROPTIC
BRONCHOSCOPE
FIBEROPTIC II
Disadvantages
Expensive
 Requires careful maintenance
 Presence of blood or secretion


Impairs visualization.
