DSE Flashcards
A patient has recently had a stroke. What is your first concern?
- When was their last cleaning
- Are they on anticoagulants
- current blood pressure
Are they on anticoagulants
- Stroke patients could be on blood thinners, such as aspirin, dipyradamole (Persan- tine), clopidogrol (Plavix), or Coumadin, postrecovery. Prior to major surgery, always consult with the patient’s physician to determine whether and when the blood thinners can be stopped and subsequently restarted.
- Following a CVA that required significant hospitalization, routine dental treatment must be delayed by 6 months.
- Routine dental treatment should be delayed by 3 months if the post-CVA recovery was uneventful and the patient was admitted overnight just for observation.
- Avoid epinephrine containing LAs during the first 6 months of dental treatment. Subsequent use of epinephrine depends on the patient’s prognosis. Epinephrine containing LAs can be used starting 1 year after the stroke, when the patient demonstrates progressive improvement of the CVA and absence of TIAs.
