摘要: The study examines blood reflux into cartridges under infiltration anesthesia. When imitation examination was carried out using Pontamine blue dye solution in 7 kinds of syringes cartridges, observed all them. Dye but 1 4 on the market. amounts protein residual anesthetic after anesthesia were quantitatively measured by a binding method. Human hemoglobin also enzyme immunoassay (EIA). detection rates and human 26.2% (85/324) 24.2% (24/99), respectively. Study results show that cannot be avoided cartridge system so reuse from should prohibited as quickly possible to avert risk cross-infection HB AIDS virus.
