血液保存对红细胞携氧功能及能量代谢的影响
Effect of blood storage on RBC oxygen-carrying function and energy metabolism
摘要
Abstract
Objective To evaluate the impact of storage time and pre-treatment process on the oxygen-carrying func-tion and energy metabolism of red blood cells. Methods Oxygen-carrying capacity was measured by HEMOX-ANALYZ-ER, and the concentrations of glucose, Na+ ,K+ and lactate dehydrogenase were also detected at different storage time. Results The effective oxygen-carrylng volume of whole blood and suspended RBC decreased by 27.5% and 19.2%, re-spectively after 1 week, and at the end of preservation, the volume decreased to 39% and 51%, respectively. P50 values decreased during the preservation period, which was reduced sharply at the first two weeks, but then showed no significant change. Glucose level gradually reduced, and lactate dehydrogenase increased rapidly with storage time, and tripled at the end of storage. Na+ concentration declined, and K+ concentration gradually increased. K+ of suspension RBC also tripled at the end of storage. Conclusion Blood storage time and pre-treatment process have an important impact on RBC oxygen-carrying function and energy metabolism. Such treatments as filtration, centrifugatiun and others could result in a one-time injury to RBC.关键词
