  • of maxilofacial surgery King Saud University

2
Preparation for medical emergencies
_ Personal continuing education -- auxiliary
staff education --- establishment and periodic
testing of a system to access medical
assistance ----equipping office with supplies
necessary for emergency care
3
Basic life support
Abcs A air way B breathing C circulation

Chest Discomfort
16
Chest Discomfort
Differential diagnosis of acute onset chest pain
Common causes- CVS Angina pectoris, MI. GIT
Gastric ulcers, reflux eosphagitis, dyspepsia. M
SK S Intercostal muscle spasm, rib or muscle
contusion. Psychogenic Hyperventilation.
17
Uncommon causes- CVS Pericarditis. GIT
Esophageal rupture. M SK S Osteocondritis. RESP
S Pulmonary embolism, pleuritis, mediastinitis,
pneumothorax. Psychogenic imagined chest pain
18
Clinical characteristics of chest pain caused by
myocardial ischemia or infarction Pain or
discomfort described by the patient 1-
Squeezing, pressing, burning, choking, or
crushing in character ( not typically sharp or
stabbing in quality) 2- Substernally located with
variable radiation to left shoulder, arm,
left side, or combination of these areas with
neck and mandible.. 3- Frequently associated
with exertion, heavy meal, anxiety, or
assuming horizontal position. 4- Relived with
vasodilator (nitroglycrin), or rest (as in
angina). 5- accompanied by dyspnea, nausea,
weakness,, palpitations
19
Management of patient with chest pain- 1-
terminate all procedures 2- position patient in
semi-reclined position 3- give nitroglycrin
(TNG) 0.4 mg tab or spray 4- oxygen 5- check
pulse and blood pressure
Discomfort continues after 3 m of TNG 6- Give 2ed
TNG dose. 7- monitor vital signs
Discomfort relived 6- assume angina p. present 7-
slowly taper oxygen. 8- modify dental treatment
Discomfort continues after 3 m of TNG 8- Give 3ed
TNG dose. 9- monitor vital signs
20
Discomfort relived 10- refer patient to medical
evaluation before further dental care
Discomfort continues after 3 minutes of 3ed
TNG 10- Assume MI in progress. 11- start IV
line 12- to relive the discomfort morphine
sulfate 2mg subcutaneously or intravenously
every 3 minutes until pain relived. 13- prepare
for transport to emergency care.

26
Management 1- terminate the procedures 2-
patient in fully sitting position. 3-bronchodilato
r (isoproterenol). 4- oxygen. 5- monitor vital
signs

dental ttt until consultation.

30

in almost fully upright position. 3-verbally
calm the patient 4- patient breath Co2 enriched
air, such as in a small bag.

position 6-begin abdominal thrusts followed by
turning pt. on side and use the finger to sweep
the oral cavity for foreign body 7-ventillate
