Managing Increased Brain Pressure. Hospital staff should watch carefully for increased pressure on the brain, which is a frequent complication of hemorrhagic strokes. It can also occur a few days after ischemic strokes. Early symptoms of increased brain pressure are drowsiness, confusion, lethargy, weakness, and headache. Medications such as mannitol may be given during a stroke to reduce pressure or the risk for it.
Keeping the top of the body higher than the lower part, such as by elevating the head of the bed, can reduce pressure in the brain and is standard practice for patients with ischemic stroke. However, this practice also lowers blood pressure in general, which may be dangerous for patients with massive stroke.
Monitoring the Heart. Heart attack and arrhythmias are potential complications of ischemic stroke. Patients must be monitored using electrocardiographic tracings.
Controlling Glucose Levels. Elevated blood sugar (glucose) levels can occur with severe stroke and may be a marker of serious trouble. In general, it is advisable to lower glucose levels that are about 300 mg/dL, usually with insulin. It is not clear, however, if glucose-lowering treatments offer any advantage. Excessive lowering of glucose levels can have damaging effects on the brain. Studies are underway to determine the best approach.
