Critically ill patients

Critically ill patients are those who are in serious
condition, and may possibly have the danger of
life-threatening at any moment.
The basis to successful resuscitation is timely,
comprehensive and accurate observation and
recording of the patients’ condition.
 The key to successful resuscitation is to
apply all the resuscitation techniques
skillfully.
The guarantee to successful resuscitation is
the organization and management of rescuing
work.

Observation of consciousness
Consciousness is the comprehensive reflection

Coma
Deep coma
Glasgow Coma Scale, GCS
The scale comprises three tests:
 eyes opening (4 grades)
 verbal response (5 grades)
 and motor responses (6 grades)


The highest possible GCS (the sum) is 15 (fully awake
person), while the lowest is 3 (deep coma or death).
If the score is less than 7 and more than 3, it’s light coma.
Best eye response
There are 4 grades starting with the most severe:




No eye opening.......................................1
Eye opening in response to pain...........2
Eye opening to speech ..........................3
Eye opening spontaneously.................4
Best verbal response
There are 5 grades starting with the most severe:

Observation of pupils


The shape, size and symmetry of pupils
Light reaction
Shrinking:
the diameter of a pupil is smaller than 2mm.


Bilateral pupil diminished may be seen when there
are poisoning conditions of organophosphorous
insecticides( 有 机磷 农药 ), chlorpromazine( 氯丙嗪 )
and morphine(吗啡).
Unilateral pupil diminished may indicate the
earlier stage of transtentorial hernia(小脑幕裂孔疝).
Largening:
the diameter of a pupil is bigger than 5mm, (mydriasis)


Bilateral pupil dilated commonly is seen with the
state of intracranial hypertension( 颅 内 高 压 ),
craniocerebral injury ( 颅 脑 损 伤 ), Belladonna
poisoning (颠茄类药物中毒) and dying.
One side pupil dilated and fixed may indicate the
occurrence of transtentorial hernia (小脑幕裂孔疝)
which caused by same side intracranial hematoma
(颅内血肿) or brain tumor.

Resuscitation skills commonly used


Cardio-pulmonary Resuscitation (CPR)
Gastric lavage
Sudden cardiac arrest，SCA

CPR is a combination of oral resuscitation that
supplies oxygen to the lungs, and external cardiac
massage (chest compression), which is intended to
reestablish cardiac pump function and blood
circulation.
(Heart-lung resuscitation)
oral
resuscitation
chest
compression
when a cardiac arrest or respiratory arrest occurs,
a combined effort is made to restore or maintain
respiration and circulation, artificially.
The cardinal signs of a cardiac arrest







unconsciousness
absence of a carotid pulse
apnea
dilated pupils
pale or cyanosed skin
absence of heart sounds
nil bleeding from wound
compression

Basic Life Support (BLS) airway
breathing
Advanced life support(ALS)
Prolonged life support(PLS)
Purpose
To establish artificial circulation and respiration
To circulate oxygenation blood to the vital
organs to prevent permanent tissue damage

Indications
Cardiac arrest and/or respiratory arrest
 Contraindications
Presence of heart beat and breathing
Severe injuries to thorax or heart
Severe deformity of thorax and spine

Stethoscope
Oral airway or face mask if available
Ambu bag if available
Procedures-Assess whether victim is unconscious:

shaking client's shoulders gently

shouting
Procedures-If victim is not responsive,
activate Emergency medical
Services -EMS (call 120).
120
Procedures-


Place the client on hard surface
Place the client in supine position
Take away pillow under client's head and loosen
client's collar and belt
Procedures-check the carotid pulse
Locate it by placing two
fingers in the groove between
the Adam’s apple and the
muscle.
★If there is a pulse
★If there is no pulse
＜10s
If there is a pulse

ventilate victim at rate of one breath every 5
seconds (10-12/min)

Recheck the carotid pulse every 2 minutes

If breathing resumes, observe carefully to verify
continued spontaneous respiration.
If there is no pulse,
initiate chest compression
A person in bed must be moved to the floor,
or a cardiac board.
Locate the position for compression
Place the hands on the breastbone at the nipple line.
Place another hand on
top of the hand
the heel of the
hand
Keep fingers off
chest wall


Extend arms and lock elbow.
Maintain arms straight and
shoulders directly over victim’s
sternum.

Press straight down on the sternum,
compressing the chest 5 cm.

Then release pressure, maintaining
contact with skin.

Give compressions at rate of 100 /min,
counting “one and two and,” etc, up to 30.
Procedure-- open airway
head-tilt, chin-lift method
a.Place palm of one hand on
victim’s forehead.
b.Place fingers of another
hand under victim’s chin.
c.Simultaneously push down
on forehead and lift
upward on chin.
Use care to
avoid pressure
on the soft
tissue of the
throat.
jaw thrust method
—If head or neck trauma is suspected

grasp angles of victim's
lower jaw and lift with
both hands, displacing
mandible forward.
If victim is not breathing,
administer artificial breathing
Mouth-to-mouth
Mouth-to-nose
Mouth-to-mouth/ nose
Mouth-to-mouth resuscitation
a. Pinch nostrils together.
b. take a deep breath and place mouth over the
victim’s mouth, forming a tight seal.
c. Blow two full breathes into the client's mouth (each
breath should last 1 second); allow the client to
exhale between breathes by loosing the nose.
Mouth-to-nose resuscitation

Keep victim's head tilted with one hand on forehead.

Use another hand to lift jaw and close mouth.

Seal nurse's lips around victim's nose and blow.

Allow passive exhalation.

After 2 full ventilations,
reposition hands correctly,
give 30 compressions.
The ratio of compressions to breath is 30 to
2 for one or two rescuer.

After the 5 cycle CPR, check carotid pulse and
resume CPR if absent.

Recheck pulse every few minutes, but do not
interrupt CPR for more than 10s.

Pulse should also be checked if signs of recovery such
as movement, swallowing, or returning facial color
occur.

If pulse is present, continue ventilations every 5s
without compressions if the client does not resume
breathing.

Continue CPR until heartbeat and breathing are
restored, EMS arrives, or victim is pronounced dead
by a physician.

If heartbeat and breathing resume, continue to
observe and arrange for transport of victim to
hospital.

Gastric lavage is a medical approach for
therapeutic irrigation of stomach by inserting a
gastrolavage tube to stomach via mouth or nasal
cavity, through which certain quantity of
irrigating solution is pumped into stomach by
gravity, siphonage, and negative pressure suction.
Purpose



Acute toxicosis,
especially within 6h
after it
Detoxification: Clear the stomach contents or
other harmful substance.
Alleviate the edema of stomach mucosa: Wash out
food in stomach; Alleviate stimulation, edema and
inflammation of stomach mucosa.
