Q
How to manage a case of arterial hypertension?
A
- patient is instructed to take their medication as usual on the day of dental treatment
- the patient blood pressure should be recorded, and if the values high: postpone
- the prescription of anxiolytic agents may prove necessary in particularly anxious patients (5-10 mg of diazepam the night before and 1-2 hours before the appointment) before dental treatment
- a good local anaesthetic technique should be performed, avoiding IV injection and using a maximum of two anaesthetic carpules with vasoconstrictor. If more anaesthesia is needed, it should be provided without vasoconstrictor

- if persists, treat as for ‘severe symptoms’: myocardial infarction, call for help
- if the patient loses consciousness commence basic life support procedures
30
What is the procedure to take if acute myocardial infarction happens?
- in dental practice, a minimum safety period of 6 months has been established before any oral surgical procedure can be carried out: in this time, dental treatment should be limited to emergency procedures aimed at affording pain relief (extractions, the drainage of abscesses and pulpectomies)
- if the patient is receiving anticoagulants, the international normalized ratio (INR) on the day of treatment should be determined, and treatment should be provided within the recommended limits (< 2.5)
