目的:探讨心脏骤停后延迟心肺复苏对大鼠海马病理变化的影响。方法成年雄性SD大鼠54只,随机分为假手术组(S组)、即刻复苏组(A组),延迟复苏组(B组),每组按血管穿刺后(S组)或自主循环恢复(ROSC)后(A组、B组)0.5 h断头取海马。A组、B组采用窒息法致大鼠心脏骤停和心肺复苏模型。光学显微镜下观察海马病理变化。结果光镜下,S组海马神经元表现为细胞形态、分布正常,几乎无变性、坏死神经元;与S组比较,A组、B组海马神经元可见明显的细胞水肿、核固缩等病理改变,且B组比A组损伤更为严重。结论延迟心肺复苏不仅降低心脏骤停大鼠ROSC成功率,亦可加重海马组织病理损伤。
目的:探討心髒驟停後延遲心肺複囌對大鼠海馬病理變化的影響。方法成年雄性SD大鼠54隻,隨機分為假手術組(S組)、即刻複囌組(A組),延遲複囌組(B組),每組按血管穿刺後(S組)或自主循環恢複(ROSC)後(A組、B組)0.5 h斷頭取海馬。A組、B組採用窒息法緻大鼠心髒驟停和心肺複囌模型。光學顯微鏡下觀察海馬病理變化。結果光鏡下,S組海馬神經元錶現為細胞形態、分佈正常,幾乎無變性、壞死神經元;與S組比較,A組、B組海馬神經元可見明顯的細胞水腫、覈固縮等病理改變,且B組比A組損傷更為嚴重。結論延遲心肺複囌不僅降低心髒驟停大鼠ROSC成功率,亦可加重海馬組織病理損傷。

Objective To observe the effects of delayed CPR on hippocampal pathological injuries in rats after cardiac arrest. Methods The 54 adult SD rats were randomly divided into 3 groups:sham-operation control group (S group), immediated CPR group (A group),delayed CPR group (B group).Each group was divided on 0.5h after endovascular puncture in S group or after ROSC in A,B group. Asphyxiation cardiac arrest and CPR model was used in A,B group.The pathological changes of hippocampus were observed under light microscope. Results There were serious pathological changes in delayed CPR group. Conclusion The delayed CPR not only reduced the ROSC rate,also aggravated hippocampal pathological damage in rats .
