目的 探討自制全氟化碳乳劑(PFE)靜脈輸注的安全性。方法 35只雄性Wistar大鼠隨機(jī)分為對照組(5只)和PFE組(30只)。腹腔麻醉后,對照組靜脈注射生理鹽水10 mL/kg后2 h處死,PFE組大鼠于靜脈注射PFE后5 min經(jīng)眼眶靜脈取血200 μL測定全氟化碳(PFC)濃度,然后分別于2 h,4 h,6 h,24 h,48 h,10 d分別隨機(jī)處死5只。觀察各組血液PFC濃度,PaO2水平,GPT、GOT、BUN、Cr濃度,肺臟、肝臟、腎臟常規(guī)病理變化。結(jié)果 PFE組大鼠活動、反應(yīng)正常,無1例死亡;肝臟、腎臟病理無明顯異常;PFC顆粒廣泛分布于肺泡及肺微血管。PFE組2 h,4 h,6 h,24 h時間點GPT及GOT均顯著高于對照組(P均 lt;0.05);第10 d降至(92.5±6.4)U/mL和(163.9±1.3)U/mL,與對照組比較無明顯差別。BUN、Cr水平與對照組比較無明顯差別(P均 gt;0.05)。靜脈注射PFE 10 mL/kg后5 min,2 h,4 h,6 h,24 h,48 h,10 d血中PFC濃度分別為(20±1.8)mg/mL,(1.8±0.7)mg/mL,(1.5±0.6)mg/mL,(1.2±0.4)mg/mL,(0.5±0.2)mg/mL,(0.2±0.03)mg/mL,0 mg/mL。PFE組2 h時間點PaO2顯著高于對照組[(119.2±8.6)mm Hg比(99.6±4.7)mm Hg,P lt;0.05]。結(jié)論 靜脈輸注PFE對大鼠一般情況、肺臟、肝臟、腎臟臟器病理無明顯影響,具有較好的安全性。靜脈輸注PFE后PFC顆??蓮V泛分布于肺泡及肺微血管,并顯著提高健康大鼠PaO2,可試用于急性肺損傷的防治研究。
