tissue plasminogen activator; identifying major barriers related to intravenous injection in ischemic acute cerebral infraction

background: in patients with acute ischemic cerebral infarction, thrombolytic therapy using intravenous tissue plasminogen activator (iv?tpa) necessitates precise documentation of symptoms’ onset. the aim of this study was to identify major barriers related to the iv?tpa injection in such patients. materials and methods: between 2014 and 2015, patients with definitive diagnosis of acute cerebral infarction ( n = 180) who attended the neurology ward located at the isfahan alzahra hospital were studied. to investigate barriers related to door to iv?tpa needle time, personal reasons, and criteria for inclusion or exclusion of patients, three questionnaires were designed based on the food and drug  administration?approved indications or contraindications. results: the mean age of males versus females was 77.5 versus years (ranged 23–93 vs. 29–70 years), respectively. out of total population, only 10.7% transferred to hospital in <4.5 h after the onset of symptoms. regarding eligibility for iv?tpa, 68.9% of total population have had criteria for such treatment. concerning to both items such as transferring to hospital in <4.5 h after the onset of symptoms and eligibility for iv?tpa, only 6.6% of total population met the criteria for such management. there was ignorance or inattention to symptoms in 75% of population studied. there was a mean of 195.92 ± 6.65 min (182.8–209.04 min) for door to iv?tpa needle time. conclusion: despite the international guidelines for iv?tpa injection within 3–4.5 h of ischemic stroke symptoms’ onset, the results of this study revealed that falling time due to ignorance of symptoms, literacy, and living alone might need further attention. as a result, to decrease death and disability, educational programs related to the symptoms’ onset in isfahan/iran seem to be  advantageous.
