Check STAT fibrinogen and platelets. Give Amicar epsilon aminocaproic acid 5 grams over 20 minutes. If the platelets are: less than K, give 1 plateletpheresis unit. Now what do you do? Call the chaplain? Is there anything else we can do to reverse the effects of tPA? Finding that balance between improving outcomes in acute ischemic stroke, while seeking to limit adverse effects, has been quite difficult.

In select patient populations the benefit of this therapy exceeds the risk. Although it occurs in a minority of patients, ICH post administration of tPA can be quite catastrophic. Knowing the next steps in these time-sensitive moments is a cornerstone of management. The first step in treating a post-tPA hemorrhage starts before stroke treatment : tPA should be avoided in high-risk scenarios, and each patient should be risk stratified prior to tPA infusion.

High risk factors include an elevated glucose or a history of diabetes, a high National Institutes of Health Stroke Scale NIHSS score, advanced age, elevated blood pressure, thrombocytopenia, and any history of congestive heart failure. An article by Saver, et al in Stroke in defined the number needed to harm with tPA. Provided that a patient is selected that is consistent with the NINDS trial, for every people treated with tPA, there would be about 2.

Harm was defined as an increase in at least one point on the modified Rankin scale. On the other side, about 16 people per hundred will benefit from treatment. What if a hemorrhage does occur? In in the journal Neurocritical Care , Norby, et al looked at that very question in regard to prognosis. Unfortunately for patients with symptomatic intracerebral hemorrhage sICH after receiving tPA, there is a paucity of data to support any one therapeutic intervention.

We are limited to case reports and theoretical recommendations from experts. The American Heart Association and American Stroke Association guidelines for management of ischemic stroke note there is no standardized protocol or guideline for managing these patients. Tissue plasminogen activator works by converting plasminogen to plasmin, which subsequently degrades fibrin.

Anti-fibrinolytics work in the opposite manner by competitively inhibiting the activation of plasminogen to plasmin. In one of its largest trials, TXA was shown to reduce the risk of all-cause mortality in bleeding trauma patients. This study showed neither a benefit nor detrimental effect on ICH. A head CT obtained 3 hours later revealed no further expansion of the bleeding. Methods: This is a case report of a Jehovah's Witness patient who was unwilling to receive blood products after developing symptomatic ICH following i.

He consequently received TXA for reversal of thrombolytic therapy. Results: The patient received a total of 1. TXA within 3 h of finishing the iv tPA.
