- Abstract
- Objective: To observe the relationship between the preservation days of banked blood and the alteration level of plasma cholinesterase with the aim of making proper selection of banked blood in emergency treatment of acute organophosphorus pesticide poisoning. Methods : We selected at random the banked blood that has been stored for different length of time before blood transfusion so as to determine the plasma cholinesterase value. The normal plasma cholinesterase value was determined on blood samples in the Blood Center which served as a control group. The cholinesterase value was determined with a kot of the BM Company and the Cobas -Fara II automatic analysis of the Roch Company. Results :It was found that there was nosignificant difference of plasma cholinesterase value between the one-day banked blood and the normal control group, but the plasma cholinesterase values of the other experiment groups were all significantly lower than that of the control group. As compared with the normal control group, the relative ratio with fixed base was about from 80 percent to 16 percent. It seems that the preservation days are in negative correlation with the cholinesterase value. The curvilinear regression equation is Y=-1 823.3 Ln(X)±6 229.4. Conclusion :With the increase of the banked blood preservation days after blood sampling, the plasma cholinesterase value decreased gradually. So in the emergency treatment of severe AOPP, it is essential to use the fresh blood collected within one day, so as to avoid missing the chance of first-aid treatment. This study provides the experinental basis for emphasizing transfusion of frech blood and experimental basis for enphasizing transfusion of Fresh blood and ensuring transfusion of highly active cholinesterase in treation AOPP.
