Risk of cross-infection related to the multiple use of disposable syringes.

摘要: The rate of blood contamination IV tubings used in anaesthesia practice was investigated. Only started the operating room were studied. First, 300 three different types tested at distal injection sites. 3.3 per cent site closest to catheter and 0.3 furthest. presence a checkvalve did not affect rate. Second, third sites fixed level equal or above tested. None them contaminated. Finally, order evaluate whether changing needle alone could prevent syringes, injections made into tubing where flowing. Thirty-four syringes positive for blood. We conclude that have significant usual practice. This decreases as distance from increases. use carries lower risk contamination. Changing is useless procedure crosscontamination.
