Oropharyngeal / Guedel Airway
• This is essentially a rigid, curved
plastic tube. It is an airway adjunct
• It is used to provide an airway for
a patient where there is an
impaired level of consciousness.
• It is sized by measuring the
distance from the angle of the
mandible to the patient’s
mouth.
• It is inserted upside down into the
mouth and rotated downwards
when it is past the tongue within
the oral cavity.

Airway Instruments
Endotracheal Tube
• Used to provide a definitive airway for
patients. This means a cuff is inflated
to prevent aspiration. Used for long
operations, (laparotomy) and in cases
of inhalation injury, (burns)
• Indications:
– Depressed consciousness
– Hypoxemia
– Airway Obstruction
Airway Instruments
Endotracheal Tube
• Then check the tube is in the trachea by:
– Auscultating: ensure bilateral breath
sounds
– Auscultate over the stomach (epigastric
region) to ensure no gurgling (that would
indicate oesophageal intubation)
– Measure end tidal CO2 tension: since
CO2 is produced in the lung, you can
confirm that the tube is in the trachea by
measuring the end tidal CO2 tension. If
the tube is in the oesophagus, then the
CO2 gas pattern would be absent.
– Do CXR and look for metallic mark

• Complications:
– Broken Teeth, lacerations of the
tissues of the upper airway,
– Intubation of the Oesophagus

Tracheostomy Tube
• Definitive airway
• Tracheostomy = surgical
opening into the trachea.
• Can be temporary or
permanent.
• It involves placing the
tracheostomy in between the 2
and 4th tracheal rings.
• Usually done in theatre under
GA.

– Patients who require long term intubation
(>2 weeks) – better tolerated than ETT
– Severe maxillofacial injury (unable to
intubate)
– Post-laryngeal surgery (e.g. laryngectomy
for malignancy)
– Lung disease (e.g. COPD) to reduce dead
space and allow effective ventilation
– Obstructive sleep apnoea
– Upper airway obstruction

Laryngoscope
• A laryngoscope has a handle and a
curved blade, usually fitted with a
light, it moves the tongue and
epiglottis aside in order to inspect the
larynx.
• It is used to aid insertion of an
endotracheal tube or for examination.
Airway Instruments
Airway Instruments
Laryngeal mask Airway
• Sits on top of the larynx and therefore
does not intubate the trachea.
• It is used to assist a patient with
impaired breathing. It can also be
used as an airway during short
operations e.g. day cases.
• It is inserted and then the inflatable
cuff over the larynx can be pumped,
by pushing air from a syringe, into the
blue lumen.

Proctoscope (Gabriel)
• Used to visualise the anal canal and
lower rectum
• It is also used when injecting or
banding haemorrhoids.
• After explaining the procedure to the
patient, the patient is placed in the
left lateral position and a digital rectal
examination is performed.
• The proctoscope is then attached to a
light source and lubricated prior to its
insertion into the rectum.

Rigid Sigmoidoscope
•
•
•
•
•
•
Used for the inspection of the rectum and
lower sigmoid colon.
After explaining to the patient what you
are about to do, you must attach a light
source and a air pumping device.
The patient is placed in the left lateral
position and a digital rectal examination is
performed.
The sigmoidoscope is then lubricated with
jelly and inserted pointing towards the
umbilicus.
Air is pumped into the rectum to allow
you see the direction of the rectal lumen.
Biopsies can also be taken of rectal
mucosa through the sigmoidoscope eg in
a case of ulcerative colitis

good apposition until such a time as
the natural healing process is
sufficiently well established to make
the support from the suture material
unnecessary and redundant

Saline
Crystalloids are an electrolyte solution in
water. It can pass through a semipermeable membrane (cell wall).
NaCl saline 0.9% solution is an isotonic
fluid as it has similar Na+ levels to the
extracellular fluid in the body. Saline
distributes throughout the ECF (not the
ICF like dextrose does). The ECF consists
of plasma, interstitial fluid and
transcellular fluid (note colloids stay in
the plasma). Saline is a good
maintenance fluid.

Cannulas
This is a an IV cannula. It is used to give IV fluids
and IV drugs.
If you wish to give the fluid quickly, the cannula
must be short and large bore (Poiseuille’s law –
flow is proportional to the fourth power of the
internal radius of the tube and inversely
proportional to the length).
Emergencies (265ml/min)
Generally insert a 18G (green) or higher when
giving drugs. Emergency should be brown (14G)
which has a flow rate of about 265ml/min. Use
antecubital fossae in emergencies. If you cannot
get it, use femorals.

patients), unlike the Ryle’s NG tube which is
wide bore. Note the end has a cap (not
present in Ryle’s NG tube). It is made from
silastic, which tends to block less often.
•
Another indication is oesophageal obstruction.
•
DO NOT use is patients with basal skull
fractures, facial trauma or if patient refuses it.

Hickmann Line
•
This is a Hickman line. It is a modified central line that is
tunnelled under the skin to make it more secure. It is
used as a long term central vascular access device. It is
usually inserted into the right subclavian vein.
•
The Hickmann line is a central line as it is inserted into a
central vein (therefore making it a central venous access
device). It is used mainly for long term access to the
central line. This can be for providing patient with TPN
or for taking blood or administering drugs long term.
•
The line is tunnelled under the skin, therefore you will
see subcutaneous swelling under the skin along the path
of the catheter (CVP catheters are not tunnelled and
they are used for short term only).
Lines

Peripherally Inserted Central Catheter (PICC)
These lines are inserted into a
peripheral vein, usually the cephalic
vein in the antecubital fossa and
'unwound' upwards into the
subclavian vein/superior vena cava.
They are firmly secured with tape or
sutures.
They tend to be used for relatively
short-term venous access, e.g. a
prolonged course of antibiotics, but
can be used for periods of up to
several months.

Drains
• A surgical drain is a tube
used to remove pus, blood
or other fluids from a
wound.
•Broadly classified as:
– Tube Drains
– Corrugated Drains
• Types
of drainage systems
–Closed
–Open
–Passive
–Active
Drains
Drains
Chest Drain Bottle
•Bottle to which the chest drain is attached.
• There is a line called prime level which is filled
with sterile water.
• The chest drain tubing is connected to a tube
which is under the sterile water and therefore acts
as a water seal.
•After a chest drain has been inserted you can see
bubbling in the water as the air leaves the pleural
space.
•The chest drain bottle can be used to collect air,
blood, fluid and pus from the pleural space.
•The system can be driven by attaching suction to
the top of the bottle making it an example of a
active closed drainage system
