Effect of stroke center on treatment time and short-term prognosis of patients with ultra-early acute cerebral infarction treated with intravenous thrombolysis / 中国医师进修杂志

ABSTRACT

Objective:To investigate the effect of stroke center on the treatment time and short-term prognosis in patients with ultra-early acute cerebral infarction (ACI) within 6 h treated with intravenous thrombolysis.Methods:The clinical data of 113 patients with ultra-early ACI treated with intravenous thrombolysis from July 2017 to July 2019 in Chaoyang City Central Hospital, Liaoning Province were retrospectively analyzed. Among them, 40 patients who received intravenous thrombolysis before the establishment of the stroke center (from July 2017 to July 2018) were enrolled as control group, and 73 patients who received intravenous thrombolysis after the establishment of the stroke center (from August 2018 to July 2019) were as study group. The treatment time nodes were recorded, including the time of onset, time of ACI initial diagnosis, time of completing blood collection and index reporting, time of completing CT examination and diagnosis, time of informed consent and time of onset of intravenous thrombolysis. The short-term prognosis indexes were recorded, including the mortality rate, effective rate of intravenous thrombolysis, improvement rate of neurological deficit at discharge and length of stay.Results:The time of ACI initial diagnosis, time of informed consent and time of onset of intravenous thrombolysis in study group were significantly shorter than those in control group (5.16 ± 1.97) min vs. (10.23 ± 7.80) min, (36.26 ± 21.89) min vs. (56.23 ± 40.97) min and (85.12 ± 35.46) min vs. (126.28 ± 50.14) min, and there were statistical differences ( P<0.01); there were no statistical difference in the time of onset, time of completing blood collection and index reporting and time of completing CT examination and diagnosis between 2 groups ( P>0.05). The mortality rate in study group was significantly lower than that in control group 1.4% (1/73) vs. 12.5% (5/40), the effective rate of intravenous thrombolysis and improvement rate of neurological deficit at discharge were significantly higher than those in control group 84.9% (62/73) vs. 67.5% (27/40) and 76.7% (56/73) vs. 55.0% (22/40), and there were statistical differences ( P<0.05); there was no statistical difference in length of stay between 2 groups ( P>0.05). Conclusions:The establishment of standard stroke center can shorten the treatment time and improve the prognosis of patients with ultra-early ACI.
