Effect of thrombolytic therapy on intravenous thrombolytic therapy of DNT in acute ischemic stroke and its effect analysis / 中华急诊医学杂志

ABSTRACT

Objective Analyze the effect of emergency thrombolytic therapy on door to needle time (DNT) in patients with acute ischemic stroke (AIS) and effect.Method Selected 182 cases of AIS patients underwent intravenous thrombolysis at the First Hospital of Qinhuangdao from May 2015 to June 2017.Thrombolytic therapy group (83 cases),for the May 2015-May 2016 after neurological consultation intravenous thrombolysis patients;Emergency thrombolytic group(99 cases),for the June 2016-June 2017 emergency thrombolysis group Emergency Department of intravenous thrombolysis patients.Compare the two groups of DNT,thrombolytic therapy 24 h symptomatic hemorrhage conversion rate,Thrombolysis 24 h,7 dNIHSS score,7 dthrombolysis and 3 months thrombolysis and thrombolysis 3 months improved Rankin score (mRs).Results There was no significant difference in baseline characteristics between the two groups (P＞0.05).Compared with the consultation group,the DNT[(69.77±11.66)min vs (80.12±15.49) min,t=5.745,P ＜ 0.01] of emergency thrombolytic group was significantly shortened,and the good score[39(39.4％) vs 21(25.3％),x2=4.272,P=0.039] at 3 months after treatment was significantly higher (P＜0.05);Treatment of 24 h intracranial hemorrhage conversion rate[12(12.12％) vs 5(6.02％),x2=1.982,P=0.159]、Treatment 7d mortality rate [10(10.10％) vs 6(7.22％),x2=0.464,P=0.496],3 months mortality rate [14(14.14％) vs 11 (13.25％),x2=0.030,P=0.862]、There was no significant difference in the 24h effective rate [57(57.6％) vs 53(63.8％),x2=0.745,P=0.388] and 7d effective rate [50(50.5％) vs 46(55.4％),x2=0.438,P0.508] after treatment (P＞0.05).Conclusions The emergency thrombolytic model can shorten the DNT of rt-PA intravenous thrombolysis in patients with AIS.The safety and efficacy of DNT are not different from the neurological consultation mode,and can improve the good prognosis rate.
