【摘要】 目的:观察血小板单核细胞聚集体(PMA)在全麻手术前后及术后3 d的变化,了解检测PMA对全麻手术前后血栓形成预测的意义。方法:流式细胞术检测112例全麻手术患者手术前、手术后及手术后3 d CD62p、CD63、PMA的表达,比较其在3个不同时间的差异。结果:112例患者麻醉诱导前、手术后、术后3 d CD62p的表达分别为(16.74±9.67)%、(22.76±13.89)%、(20.12±9.83)%;CD63的表达分别为(1.35±0.94)%、(2.26±1.75)%、(1.54±0.81)%;PMA的表达分别为(26.86±5.05)%、(31.86±5.31)%、(77.69±5.72)%;手术后CD62p、CD63、PMA,术后3 d CD62p、PMA与麻醉诱导前比较差异均有统计学意义(P<0.05)。结论:PMA可以作为评价血小板活化的指標,并且是一种敏感指标,可能在预测血栓形成中有重要意义。

【Abstract】 Objective: To predict the risk of thrombosis in patients with surgery under general anesthesia by monitoring the platelet-monocyte aggregates(PMA)level before the general anesthesia, immediately after the surgery and 3 days after the surgery. Method: Blood samples were collected from 112 cases of patients with surgery under the general anesthesia before the general anesthesia, immediately after the surgery and 3 days after the surgery. The presentation of CD62p,CD63 and PMA were measured and compared. Result: The presentation of CD62p before the general anesthesia, immediately after the surgery and 3 days after the surgery were (16.74±9.67)%,(22.76±13.89)%,(20.12±9.83)%. The presentation of CD63 were (1.35±0.94)%,(2.26±1.75)%,(1.54±0.81)%, and the presentation of PMA were (26.86±5.05)%,(31.86±5.31)%、(77.69±5.72)%; The presentation of CD62p, CD63 and PMA immediately after surgery and the presentation of CD62p, and PMA 3 days after the surgery compared with before the general anesthesia, the differences were all statistically significant(P<0.05). Conclusion: PMA is a sensitive biomarker to evaluate the degree of platelet activation and to predict the possible postoperative thrombosis.

血栓栓塞是术后重要的并发症之一,尤其是全麻手术后,极易发生深部静脉血栓(DVT)。血小板是血栓的重要部分,血小板活化与血栓的形成更是存在着密切的关系[1]。P-选择素(CD62p)和溶酶体蛋白(CD63)均为识别活化血小板的分子标志物,CD62p被认为是血小板活化检测的“金标准”。近年来一些研究表明,血小板-白细胞聚集体(PLA),尤其是血小板单核细胞聚集体(PMA)也是血小板活化的敏感指标[2-3]。为探讨他们的关系,笔者观察了112例全麻手术患者的上述指标,现报告如下。
