目的通過體外實驗，利用正交設計方法，探討微泡強化聲溶栓的主要影響因素，并確定微泡強化聲溶栓體外實驗的優選條件。方法取50只SD雌性大鼠外周血制備標準血漿后，以100 μL標準血漿與25 μL凝血酶（0.15 U/ μL）混勻，置于37℃恒溫水浴箱分別孵育3、6、12、24 h，制備相應栓齡血栓；建立體外溶栓模型。確定4個物理參數：超聲輸出能量（因素A：5%、25%、50%、100%），微泡量（因素B：50、100、200、400 μL）；尿激酶濃度（因素C：100、200、400、800 U/mL）；超聲處理溶栓時間（因素D：10、20、30、40 min），進行四因素四水平正交實驗，建立L16（45）正交表。低頻診斷超聲頻率為1.82 MHz，進行體外溶栓實驗。組織學及掃描電鏡觀察溶栓前后血栓結構。溶栓前后進行血栓稱重，計算溶栓率，并進行統計學分析。結果組織學及掃描電鏡觀察各栓齡血栓溶栓后，血栓纖維網架被破壞。體外條件下最優溶栓條件組合為C4-D4-A1-B4，即：尿激酶濃度800 U/mL、溶栓時間40 min、超聲輸出能量5%、微泡量400 μL。4個物理參數對各栓齡血栓溶栓效果均有顯著影響（P lt; 0.05），其中尿激酶濃度對溶栓率影響最顯著。血栓栓齡顯著影響溶栓效果，差異有統計學意義（P lt; 0.05）。結論微泡強化聲溶栓效果可靠，尿激酶起主導溶栓作用。低超聲輸出能量、高造影劑微泡量、長超聲輻照時間以及短栓齡有助于溶栓效果的提高。
