textbook medical emergencies Flashcards
what is the ABCDE approach?
A - airway - ensure kept open B - breathing - resp rate C - circulation - pulse/BP D - disability - consciousness/ glucose levels E - exposure - skin rashes/odeama
when is oxygen used in medical emergencies?
what rate is it given at?
what does it prevent?
most emergencies but not useful in hyperventilation
10-15l/min
prevents cerebral hypoxia
what is epinephrine used for?
what dose is it given at?
what is its action?
anaphylactic shock
0.5mL at 5 min intervals when necessary
- suppresses histamine release, vasoconstriction, increased rate and force of cardiac contraction
relaxation of airways
what is glucose used for?
what dosage?
action?
hypoglycaemia in a conscious patient
10-20g given orally
elevates glucose levels quickly
what is glucagon used for?
what dosage?
action?
hypoglycaemia in an unconsciuos patient
1mg
children 0.5mg
increases glucose by converting glycogen to glucose
what is salbutamol used for?
dosage?
action?
200mg - 2 puffs
asthma
relaxes bronchial muscle and allows increased airway size
what is glycerol trinitrate used for?
dosage?
action?
cardiac chest pain and angina
400mg
vasodilation of coronary arteries = better blood flow
what is aspirin used in the treatment of?
what dose?
what does it do?
myocardial infarction
300mg
antithrombotic effect reduces mortality
what is midazolam used in the treatment of?
dosage?
action?
epileptic patient
10mg
inhibit CNS activity = anti epileptic effect
management of conscious choking patient?
- encourage coughing to disrupt blockage
- remove obvious debris from mouth
5 back blows and 5 abdo thrusts
management of choking patient once unconscious?
open airway and 2 effective breaths
30 chest compressions
how to manage choking child?
baby/small child - hold upside down and 5 back blows
- back blows, abdo thrusts, chest thrusts
how to open airways?
head tilt chin lift
jaw thrust
adjuncts used to maintain airways?
supplemental oxygen
oropharyngeal airways - match by measuring incisors to angle of mandible
faint signs and symptoms?
unwell, weak, dizzy
pallor/sweating
bradycardia - bpm <60
