Common Emergency Situations are:
Fainting (Vasovagal Syncope )
Diabetic Coma
Anaphylactic Shock
Epileptic Seizures
Cardiovascular Collapse (CVC)
Thyroid Crises
Adrenal Crises
Asthmatic Attack
Stroke (Cerebro-vascular Accident, CVA)
Sudden loss of consciousness
Chest pain & dyspnea
Convulsions (fits)
Predisposing factors
Signs & symptoms
Differential diagnosis
(The Main Problem of every Systemic Condition)
Management
Reassess
(The General Procedures of Maintaining the Pt Life;
VS + Specific Management for each Condition)
Vaso-vagal syncope
Acute Hypoglycaemia
Anaphylactic shock
Steroid crisis
Myocardial Infarction
Cardiac Arrest
CVA
Angina
Myocardial Infarction
Asthma
Anaphylactic Shock
Epilepsy
Any other cause of loss of consciousness
including fainting
Anxiety
Pain
Injections
Fatigue
Hunger
Premonitory dizziness, weakness & nausea
Pale, cold moist skin
Pulse initially slow & weak, becoming full &
bounding
Lay flat & lift legs
Loosen tight clothing around neck
Give sweetened drink on regaining consciousness
Prolonged faint, Atropine 600 mcg/ml slow IV (1
ml only)
Good history
Reassurance
General Anxiety (Stress) Reduction Protocol
Well fed prior to treatment
Glucose drink
10 mg Temazepam nocte (prior to appt) & 1 hour
before treatment
Delay the procedure
Drugs e.g. penicillin
Insect stings
Foods, nuts, shellfish, materials
Quicker onset the more severe the reaction
Widespread vasodilatation & increase in capillary
permeability, potentially fatal hypotension
Immediate
IgE mediated
Anaphylaxis
Urticaria
Angio-oedema
Allergic Asthma
Rhinitis
•Hypersensitivity
Signs & Symptoms variable
Rapid weak or impalpable pulse
Facial flushing, itching, tingling, cold extremities
Bronchospasm (wheezing)
Loss of consciousness
Pallor going on to cyanosis
Cold, clammy skin
Facial oedema & sometimes urticaria
Deep fall in BP
Lay flat with raised legs
Give Adrenaline (1:1000) 0.3-0.5 ml SC or IM
Hydrocortisone 200 mg i.v.
Chlorpheniramine 10-20 mg slow i.v.
Give oxygen 6L/min & assisted ventilation
Consider Cricothyrotomy if NO quick improvement
Call an ambulance
CAUSES:
Overdose of insulin
Prevented from eating
at expected time
MANAGEMENT:
Glucose
tablets/powder
If unconscious give
50ml 50% glucose IV
SC glucagon 1mg
Hypoglycaemia
Hyperglycaemia
Rapid onset
Irritability
Moist skin
Pulse full & rapid
More common
Less Severe
Easy to be managed
Slow onset
Drowsiness/disorientation
Dry skin & mouth
Pulse slow & weak
Rare
More Severe
Difficult to be managed
Precipitating Factors:
Infection
Surgery
Trauma
Pregnancy
Other Physiologic or Emotional Stress
Manifestations:
Hyperpyrexia (Fever)
Tachycardia
Agitation
Palpitation
Nausia, Vomiting
Abdominal pain
Loss of
Consciousness
(Partial or Complete)
Management:
Terminate all dental ttt
Summon medical
assist
Administer O2
Monitor VS
Initiate BLS, if
necessary
Start IV line & Fluids
Transport to ER Care
CAUSES: Stress Conditions
GA
Surgical/Other
trauma
Infection
Other stress
SIGNS & SYMPTOMS
Pallor
Weakness
Nausia
Rapid, weak or
impalpable pulse
Loss of consciousness
Rapidly falling BP
Lay flat and raise legs
Hydrocortisone 200mg i.v.
Give oxygen
Monitor VS
Start BLS if necessary
Consider other possible reasons for loss of
consciousness
Ambulance & transfer to hospital
Anxiety
Infection or exposure to
specific allergen
Loss or forgetting to bring
Salbutamol inhaler
Breathlessness
Expiratory wheezing may be
disguised as shallow breathing
Rapid pulse over 110
Accessory muscles of respiration
brought into use
Cyanosis of mucous membrane &
nail beds
Mental confusion
Reassure the patient
DO NOT lay the patient flat
Give the anti asthmatic drug
normally used
Give oxygen
Give Adrenaline
Hydrocortisone 200 mg i.v.
Monitor VS
If no response to Salbutamol
500 mcg i.m/s.c., CALL AN
AMBULANCE
Acute chest pain which may
radiate to left arm or shoulder
Relieved by anti anginal drug
e.g. GTN 0.5mg sublingually
Aspirin 300mg
If symptoms do not resolve
rapidly with administration of
GTN, consider it likely that the
patient has suffered an MI
Severe, crushing retro
sternal pain
Feeling of impending death
Weak or irregular pulse
Pain may radiate to left
shoulder, arm or jaw
Shock, loss of consciousness
Vomiting
Place patient in a comfortable position allowing
easy breathing
Send for an ambulance
Give 50/50 Nitrous Oxide/Oxygen or Oxygen only
Aspirin 300mg
Good pain control
Constant reassurance
Myocardial Infarction
Hypoxia
Anaesthetic overdose
Anaphylaxis
Severe hypotension
Loss of consciousness
Absence of arterial pulse
“SUMMON HELP”
Patient on flat, firm surface
CLEAR AIRWAY (keep patent)
Start CPR
Defibrillation
Transfer patient to hospital
Severe Headache
Weakness or Paralysis of arms or legs
of one side
Unilateral Facial muscle Paralysis
Difficulty or inability to Speak
Partial or Total Loss of consciousness
Patient is very anxious, needs
reassurance and transfer to hospital
immediately, BLS, Supine Position
BUT Head slightly Elevated
Predisposing factors:
Anxiety
Hunger
Menstruation
Alcohol
External stimuli, flashing lights etc
Non compliance with medications
Warning cry
Immediate loss of consciousness
Rigid (tonic phase)
Widespread jerking (clonic phase)
Vomiting
Flaccid after a few minutes
Consciousness is regained after a variable period
Patient may remain confused
Prevent patients from damaging themselves
Place in Supine position
Maintain patent airway
No medications, await recovery
Recovery position after fits have ceased
Suctioning & Monitor VS
Oxygen
Reassure on recovery
After fully recovered requires an escort home
Continuous or repeated convulsions for 15
minutes (patient can have severe anoxia)
Give 10mg Midazolam IV repeat if no recovery
within 10 minutes
Maintain airway & give oxygen
Call an ambulance, transfer to hospital
