A patient appears to go into anaphylaxis shock in the dental chair, what steps would you follow?
- call 999, state anaphylaxis
- lie flat, administer oxygen 15litres/minute

- administer oxygen 15L/min
- note timings of seizure
- call 999 if necessary
- if seizure is prolonged (>5mins) give midazolam oromucosal solution
Why might midazolam oromucosal solution be used in the dental practise? What dosage would be used?
Prolonged convulsive seizures (> 5 mins) or repeated seizures (> 3 in one hour)
- buccal route as a single dose of 10mg
Why might glucose be used in the dental practise? What dosage would be given?
Patient suffering from a hypoglycaemic attack (able to swallow & co-operative)
- 15-20g quick acting glucose
Why might glucagon be used in the dental practise? What dosage would be given?
Patient is suffering from a hypoglycaemic attack (unable to swallow safely e.g unconscious)
- 1mg IM
what aspects should be covered when taking a patients medical history?
- cardiovascular
- respiratory
- endocrine
- gastrointestinal
- blood disorders
- seizures/fits/headaches
- mucoskeletal
THEN MEDICATIONS AT END & ALLERGY
how would you assess a patients cardiovascular health?
- do you have any heart conditions such as angina/heart attack/heart failure?
- any blood pressure problems?
- history of a stroke or clot?
how would you assess a patients respiratory health?
- do they have any breathing problems such as asthma/COPD
- do they ever use inhaler
how would you assess a patients gastrointestinal health?
- do they have any gut problems such as Crohn’s/Ulcerative colitis
- do they have any reflux or stomach problems
- any liver problems?
how would you assess a patient neurological health?
- do you have history of fits/seizures/faints
- any headache history
how would you assess a patients endocrinological health?
- any history of diabetes
- any history of thyroid dysfunction
how would you assess a patients mucoskeletal health?
- do you have any history of arthritis or joint problems?
- any bone disorders?
how would you assess if a patient has any blood disorders?
- do you experience prolonged bleeding after a cut?
- any blood disorders such as haemophilia?
- any transmitted blood disorders eg HIV/Hepatitis?
how do you know if a patients allergy to something is mild or severe?
ask if they have had any hospital admissions related to the allergy
If you suspect a patient is going through/went through a traumatic health disorder, how would you raise your concern in a polite way?
Ask if they had any previous hospital admissions/seen any specialists for a problem
How does aspirin work to help a patient suffering from a suspected heart attack?
Inhibits platelet aggregation
- thins the blood making it less likely to clot
How does GTN spray work to help a patient suffering acute anginal distress?
- Dilates veins which reduces preload to heart
- Dilates colateral coronary artery supply (reduce anginal pain)
