| | 医学论文集【摘要】 目的医学论文集 比较异丙酚和依托咪酯乳剂-宜妥利两种静脉全麻诱导药对重型创伤患者围术期T细胞免疫功能的医学论文集影响。方法 急诊重型创伤患者20例按全麻诱导用药不同分两组:异丙酚组(P组),宜妥利组(E组)。分别于全麻诱导前(T0)、诱导后5min(T1)、术毕(T2)、术后1天(T3)和术后3天(T4)检测CD3+ T淋巴细胞及亚群(CD4+、CD8+)水平。结果 两组患者的CD3+、CD4+、CD4+/CD8+术毕与诱导前相比下降明显,术后1天CD3+开始回升恢复正常,CD4+、CD4+/CD8+术后1天、术后3天逐渐上升,但均未恢复正常,在相同时间点两组间T淋巴细胞及其亚群差异均无显著性。结论 在诱导剂量范围内,异丙酚和宜妥利对重型创伤患者的T细胞免疫功能影响无明显差异。 【关键词】 T淋巴细胞亚群;全身麻醉;依托咪酯;二异丙酚 【Abstract】 Objective To compare the different changes between T-lymphocyte and immune factors in severe traumatic patients after induction.Methods Twenty severe traumatic patients undergoing emergency surgery were divided into two groups according to different general anesthetics received:Group P receiving propofol and Group E receiving etomidate.The plasma level of CD3+,CD4+,CD4+/CD8+ were detected and compared between the two groups at the time point of:before induction (T0),5 min after induction (T1),the end of surgery (T2),1 day after surgery (T3) and 3 day after surgery (T4).Results The level of CD3+,CD4+,CD4+/CD8+ were significantly decreased at the end of surgery.At the same time point, the level of the T-lymphocyte subsets were of no difference between the two groups.Conclusion At the induction dosage, the effects of propofol and etomidate on the T-lymphocyte subsets of severe traumatic patients had no significant difference. 【Key words】 T-lymphocyte subsets;general anaesthesia;etomidate;propofol 创伤后机体产生的应激反应及免疫功能的变化是机体的一种保护性反应,但是如果这一过程过于激烈或调节失衡就会造成机体抵御感染的免疫功能降低。对于创伤患者麻醉和手术其应激反应也可通过直接或间接的方式影响机体的免疫功能[1]。因此对重型创伤患者的麻醉除考虑维持患者重要脏器的血流灌注外,还应注意对其免疫功能的保护。临床研究表明,异丙酚是一种相对免疫安全的静脉麻醉药[2],但诱导剂量的异丙酚对心血管有明显的抑制作用,而依托咪酯对循环功能的影响比异丙酚轻,但其对免疫功能的影响很少论及。本课题拟就两种全麻诱导药异丙酚及宜妥利对重型创伤患者围手术期T淋巴细胞亚群的影响进行比较,探讨两种全麻诱导药对重型创伤患者免疫功能的影响。
