发布时间:2018-10-26 10:36
【摘要】:目的:分析重症患者全血胶体渗透压(Whole blood colloid osmotic pressure,COP)的影响因素,并预测维持安全COP水平(COP18mmHg)的血浆蛋白(plasma protein,PP)的参考值范围来指导蛋白制剂的使用,并使用PP参数改良已有预测COP的公式。方法:收集405例危重患者的年龄和性别等一般资料和血气分析参数,监测COP,总蛋白(total protein、TP)、白蛋白(Albumin, Alb)、球蛋白(Globumin, G1b)和纤维蛋白原(fibrinogen,FIB),根据所测得COP水平是否大于18mmHg将405例患者分为A组(COP≤18mmHg)和B组(COP18mmHg)共两组。数据使用成组t检验、多元线性回归、参考值范围估计、双变量曲线估计和非线性回归进行统计学分析。结果:A组颅内病变患者最多,其次为胃肠道疾病、产科重症和多发伤。B组的APACHE Ⅱ评分明显低于A组,B组的存活率明显高于A组(P0.05)。A组的总蛋白(TP)、白蛋白(A1b)、球蛋白(G1b)和纤维蛋白原(FIB)的水平均低于B组。多元线性回归分析结果示Alb、G1b和FIB是危重患者低COP的影响因素,Alb、 G1b和FIB的标准化回归系数依次为0.518、0.283和0.113,制定B组各类蛋白的参考值范围:TP42.8g/L、Alb23.3g/L、G1b(12.6,37.6)g/L和FIB(1.3,8.7) g/L。双变量曲线估计、多元线性回归和非线性回归拟合出6个改良后预测重症患者COP的公式。结论:COP≤18mmHg提示预后不良,全血COP的主要影响因素依次为A1b、 G1b和FIB,在危重患者G1b和FIB对COP的影响大于正常人或者普通患者。各类血浆蛋白水平的参考值范围为TP42.8g/L Alb23.3g/L、G1b(12.6,37.6)g/L、FIB(1.3,8.7)g/L,某类蛋白低于求得的允许低限时考虑补充该类蛋白制剂;若Glb和FIB过高可适当减少其他蛋白制剂的使用。改良后的公式可用于初步预测危重患者的全血胶体渗透压水平。图11幅,表6个,公式12个,参考文献56篇。
