目的：為做好參麥注射液安全性再評(píng)價(jià)工作提供數(shù)據(jù)參考。方法：滲透壓測(cè)定采用冰點(diǎn)測(cè)定法，對(duì)樣品原液及其稀釋液進(jìn)行滲透壓測(cè)定，并計(jì)算與氯化鈉注射液滲透壓的比值；溶血率測(cè)定采用分光光度法，對(duì)樣品原液及其稀釋液進(jìn)行溶血率測(cè)定。結(jié)果：滲透壓測(cè)定，樣品原液均為低滲溶液，滲透壓值在96～180 mOsmol/kg，1→4～1→8稀釋后與氯化鈉注射液滲透壓比可達(dá)0.9；溶血率測(cè)定，樣品稀釋倍數(shù)在小于1→16時(shí)，樣品均存在不同程度的溶血（溶血率＞5％），1→32倍稀釋時(shí)，溶血率均小于等于5％。結(jié)論：不同廠家生產(chǎn)的參麥注射液的滲透壓和溶血率均存在一定的差異，建議增加滲透壓和溶血率測(cè)定來(lái)控制其質(zhì)量。

Objective: To provide the data for re-evaluating the security of Shenmai Injection. Methods: Ice point method was used to determine the osmotic pressure of Shenmai Injection and its dilution solution. Ratio was calculated to NS. Spectrophotometry was utilized to measure the ratio of hemolysis. Results: All primary samples of Shenmai Injection were hyposmotic solution with osmotic pressure 96～180 mOsmol/kg. The ratio of the dilution(1→4 or 1→8)were up to 0.9. Different degrees of hemolysis occured when Shenmai Injection was diluted to less than 16 folds with the ratio of hemolysis more than 5%. But when Shenmai Injection was diluted to 32 folds, the ratio of hemolysis were less than 5%. Conclusion: There is obvious difference of osmotic pressure and hemolysis ratio among Shenmai Injection produced by different manufacturers. It was suggested that osmotic pressure and hemolysis ratio can be used to control the quality of Shenmai Injection.
