This study was designed to compare flow rates of three sets of tubings: a large bore (8 mm) Y-urologic set (Y-URO); a Y-URO with an added in-line blood filter (Y-URO + BF); and a currently used (3.5 mm diameter) blood transfusion set (Y-TRANSFUSION). The time required to empty a one litre bag of Ringer's Lactate from a 1.0 meter vertical drop was measured while using four different IV catheters (9.5, 10, 14 and 16 gauge), and the flow rates calculated. When a 9.5-gauge catheter was used, the flow rates obtained by the Y-URO and the Y-URO + BF were respectively 269 and 162 per cent higher than those achieved by the Y-TRANSFUSION. This wide margin was decreased to 41 and 39 per cent with a 16-gauge catheter. A 9.5-gauge catheter, when compared to a 16-gauge, allowed a 346 per cent improvement in flow rates with the Y-URO, a 225 per cent with the Y-URO + BF and only a 71 per cent increase with the Y-TRANSFUSION. The urologic set allows better fluid flow because of the larger diameter of its tubing. This adaptation of a large bore urologic irrigation set can be very useful when rapid fluid administration is imperative.
一种大口径(8毫米)的Y型泌尿科管道(Y-URO);一种添加了在线血液过滤器的Y-URO(Y-URO + BF);以及一种目前使用的(直径3.5毫米)输血管道(Y-TRANSFUSION)。在使用四种不同的静脉导管(9.5、10、14和16号)时,测量从1.0米垂直高度滴空一升乳酸林格氏液袋所需的时间,并计算流速。当使用9.5号导管时,Y-URO和Y-URO + BF获得的流速分别比Y-TRANSFUSION高出269%和162%。使用16号导管时,这一巨大差距降至41%和39%。与16号导管相比,9.5号导管使Y-URO的流速提高了346%,Y-URO + BF提高了225%,而Y-TRANSFUSION仅提高了71%。由于其管道直径较大,泌尿科管道允许更好的液体流动。当急需快速输液时,这种大口径泌尿科冲洗管道的应用可能非常有用。
