The use of prehensive specialized stroke care(stroke units) incorporating rehabilitation is remended(Class I, Level of Evidence A). This remendation is unchanged from the previous guideline. ? The use of standardized stroke care order sets is remended to improve general management (Class I, Level of Evidence B). This remendation was not in previous guidelines. ? Early mobilization of less severely affected patients and measures to prevent subacute plications of stroke are remended (Class I, Level of Evidence C). This remendation is unchanged from the previous guideline. ? Assessment of swallowing before starting eating or drinking is remended (Class I, Level of Evidence B). This remendation is new. ? Patients with suspected pneumonia or urinary tract infections should be treated with antibiotics (Class I, Level of Evidence B). This remendation is similar to previous guidelines. ? Subcutaneous administration of anticoagulants is remendedfor treatment of immobilized patients to prevent deep vein thrombosis (Class I, Level of Evidence A). The ideal timing for starting these medications is not known. This remendation is unchangedfrom the previous guideline. ? Treatment of conitant medical diseases is remended(Class I, Level of Evidence C). This remendation is unchanged from the previous guideline. ? Early institution of interventions to prevent recurrent stroke is remended (Class I, Level of Evidence C). This remendation is similar to previous guidelines. Class II Remendations ? 1. Patients who cannot take food and fluids orally should receive nasogastric, nasoduodenal, or PEG feedings to maintain hydration and nutrition while undergoing efforts to restore swallowing (Class IIa, Level of Evidence B). The timing of the placement of a PEG is uncertain. This remendation is new. ? 2. Aspirin is a potential intervention to prevent deep vein thrombosis but is less effective than anticoagulants(Class IIa, Level of Evidence A). This remendation has been strengthened. ? 3. The use of intermittent external pression devices is remended for treatment of patients who cannot receive anticoagulants (Class IIa, Level of Evidence B). This remendation is unchanged from the previous guideline. Class III Remendations ? 1. Nutritional supplements are not needed (Class III, Level of Evidence B). This remendation is new. ? 2. Prophylactic administration of antibiotics is not remended (Class III, Level of Evidence B). This remendation is new. ? 3. If possible, the placement of indwelling bladder catheters should be avoided because of the associated risk of urinary tract infections (Class III, Level of Evidence C). Some patients may need prolonged catheter drainage of the bladder, and measures to lower risk of infection should be taken. This remendation is similar to previous guidelines. Class I ? 1. Patients with acute primary ICH and hemiparesis/ hemiplegia should have intermittent pneumatic pression for prevention of venous thromboembolism (Class I, Level of Evidence B). ? 2. Treatment of hypertension should always be part of longterm therapy because such therapy decreases the risk of recurrent ICH (Class I, Level of Evidence B). Class II ? 1. After documentation of cessation of bleeding, lowdose subcutaneous lowmolecularweight heparin or unfractionated heparin may be considered in patients with hemiplegia after 3 to 4
