What is golden window period?
For years, the central focus for emergency department (ED) physicians responding to a patient with suspected stroke was the golden window—the roughly three-hour period following a stroke where tissue plasminogen activator (tPA) is effective without risking bleeding in the brain.
Is time important for a stroke?
Time is critical because a stroke starves brain tissue of life-giving oxygen, causing it to start to die in as little as four minutes after the beginning of a stroke. When brain tissue dies, it is gone forever.
What drug is given immediately after a stroke?
An IV injection of recombinant tissue plasminogen activator (tPA) — also called alteplase (Activase) — is the gold standard treatment for ischemic stroke. An injection of tPA is usually given through a vein in the arm with the first three hours. Sometimes, tPA can be given up to 4.5 hours after stroke symptoms started.
What is the fast treatment for a stroke?

What is meant by window period?
The window period refers to the time after infection and before seroconversion, during which markers of infection (p24 antigen and antibodies) are still absent or too scarce to be detectable. Tests cannot always detect HIV infection during the window period.
How long can a stroke last?

In the most recent study year, 2007, among the 809 facilities contributing data, GWTG-Stroke hospitals cared for 10 497 golden hour–arriving ischemic stroke patients. Table 2 shows patient- and hospital-level characteristics of 3 ischemic stroke time-of-arrival cohorts.
What are the results of the Golden Hour?
Treatment in the Golden Hour leads to excellent outcomes in all patients, irrespective of age and pre-existing comorbidity. Our study shows that improved treatment routines led to an increase in the number of patients treated within the Golden Hour.
What is the Golden Hour in emergency medicine?
Originally developed in the setting of trauma treatment, the term the “golden hour” is now a general concept in emergency medicine that is applied to conditions in which hyperacute therapy is more effective than later intervention, including trauma, myocardial ischemia, septic shock, cardiopulmonary resuscitation, and stroke.
What’s the average OTD time for a stroke?
Among the direct ED-arriving ischemic stroke patients with a documented LKWT, OTD time was 60 minutes or less in 30 220 (28.3%), 61 to 180 minutes in 33 858 (31.7%), and >180 minutes in 42 846 (40.1%). Among the subgroup who arrived within 60 minutes, mean OTD time was 39.9 minutes (SD, 14.8).
