4. Corticosteroids may be used acutely after a stroke to 
reduce the cerebral edema that accompanies cerebral 
infarction. This can markedly lessen complications. 
5. Surgical intervention may be indicated for the removal 
of a superficial hematoma or the management of 
vascular obstruction.

6. Valium, Dilantin, and other anticonvulsants are 
prescribed in the management of seizures that may 
accompany the postoperative course of stroke.

7. If the patient survives, the final task consists of the 
institution of preventive therapy, administration of 
medications that reduce the risk of another stroke 
(statins and antihypertensive drugs), and initiation of 
rehabilitation (physical and speech therapy).

3. Obtain a thorough history of stroke 
5. Monitor blood pressure and oxygen saturation. 
6. Use a minimum amount of anaesthetic  
4. Schedule short appointments.   
7. Avoid epinephrine in the gingival retraction cord.

1. Identify risk factors 
a. Hypertension* 
b. Congestive heart failure* 
c.
Diabetes mellitus* 
d. TIA or previous stroke* 
e. Increasing age ≥75 years* 
f.
Elevated blood cholesterol or lipid levels 
g. Coronary atherosclerosis 
h. Cigarette smoking 
Risk of stroke increases by a factor of 1.5 for each 
condition above indicated by*.  
Thus, having multiple risk factors listed above 
greatly increases the risk of a stroke.

2. Encourage control of risk factors  
(referral to a physician, if appropriate). 
3. Obtain a thorough history of stroke 
I.
Note the date of the event, current status, medical 
therapy, and any residual disabilities. 
II.
Provide only urgent dental care during the first 6 
months after a stroke, TIA, or Rind. 
III. Avoid elective care in patients who have had recent 
TIAS or RINDS. 
IV. Determine risk for bleeding problems in patients 
taking 
anticoagulant 
drugs, 
and 
minimize 
perioperative bleeding;

3. Obtain a thorough history of stroke 
Minimize perioperative bleeding; 
a) Aspirin + dipyridamole (Aggrenox), ticlopidine 
(Ticlid); obtain pretreatment PFA 100. 
b) Coumarin-Pretreatment INR 3.5. Higher levels 
require consultation with a physician to reduce the 
dose. 
c) Heparin (IV)—Use palliative emergency dental care 
only, or 6 to 12 hours before surgery, discontinue 
heparin, and start another anticoagulant (e.g., 
coumadin) with the physician’s approval. Then, 
restart heparin after the clot forms (6h later).

3. Obtain a thorough history of stroke 
Minimize perioperative bleeding; 
d) Heparin (subcutaneous, low molecular weight)—
generally, no changes are required. 
 
e) Use measures that minimize hemorrhage (atraumatic 
surgery, pressure, gelfoam, suturing), as needed. 
 
f) Have availab
