【摘要】:目的:分析重癥患者全血膠體滲透壓(Whole blood colloid osmotic pressure,COP)的影響因素,并預(yù)測(cè)維持安全COP水平(COP18mmHg)的血漿蛋白(plasma protein,PP)的參考值范圍來指導(dǎo)蛋白制劑的使用,并使用PP參數(shù)改良已有預(yù)測(cè)COP的公式。方法:收集405例危重患者的年齡和性別等一般資料和血?dú)夥治鰠?shù),監(jiān)測(cè)COP,總蛋白(total protein、TP)、白蛋白(Albumin, Alb)、球蛋白(Globumin, G1b)和纖維蛋白原(fibrinogen,FIB),根據(jù)所測(cè)得COP水平是否大于18mmHg將405例患者分為A組(COP≤18mmHg)和B組(COP18mmHg)共兩組。數(shù)據(jù)使用成組t檢驗(yàn)、多元線性回歸、參考值范圍估計(jì)、雙變量曲線估計(jì)和非線性回歸進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果:A組顱內(nèi)病變患者最多,其次為胃腸道疾病、產(chǎn)科重癥和多發(fā)傷。B組的APACHE Ⅱ評(píng)分明顯低于A組,B組的存活率明顯高于A組(P0.05)。A組的總蛋白(TP)、白蛋白(A1b)、球蛋白(G1b)和纖維蛋白原(FIB)的水平均低于B組。多元線性回歸分析結(jié)果示Alb、G1b和FIB是危重患者低COP的影響因素,Alb、 G1b和FIB的標(biāo)準(zhǔn)化回歸系數(shù)依次為0.518、0.283和0.113,制定B組各類蛋白的參考值范圍:TP42.8g/L、Alb23.3g/L、G1b(12.6,37.6)g/L和FIB(1.3,8.7) g/L。雙變量曲線估計(jì)、多元線性回歸和非線性回歸擬合出6個(gè)改良后預(yù)測(cè)重癥患者COP的公式。結(jié)論:COP≤18mmHg提示預(yù)后不良,全血COP的主要影響因素依次為A1b、 G1b和FIB,在危重患者G1b和FIB對(duì)COP的影響大于正常人或者普通患者。各類血漿蛋白水平的參考值范圍為TP42.8g/L Alb23.3g/L、G1b(12.6,37.6)g/L、FIB(1.3,8.7)g/L,某類蛋白低于求得的允許低限時(shí)考慮補(bǔ)充該類蛋白制劑;若Glb和FIB過高可適當(dāng)減少其他蛋白制劑的使用。改良后的公式可用于初步預(yù)測(cè)危重患者的全血膠體滲透壓水平。圖11幅,表6個(gè),公式12個(gè),參考文獻(xiàn)56篇。
[Abstract]:Objective: to analyze the influencing factors of whole blood colloid osmotic pressure (Whole blood colloid osmotic pressure,COP) in severe patients and predict the reference range of plasma protein (plasma protein,PP) to maintain safe COP level (COP18mmHg) to guide the use of protein preparations. PP parameters are used to improve the formula for predicting COP. Methods: the age and sex of 405 critically ill patients and blood gas analysis parameters were collected, and the total protein of COP, (total protein,TP), albumin (Albumin, Alb), globulin (Globumin, G1b) and fibrinogen (fibrinogen,FIB) were monitored. The patients were divided into two groups: group A (COP 鈮,
