【单选题】
传统医用纱布是在包扎伤口时利用压力去压迫伤口血管,使伤口的血液流出速度减慢,但传统纱布会大量吸收血液。中科院化学所高分子物理与化学实验室课题组与南方医科大学合作,从材料(纱布)亲水和的角度设计出一种全新概念的止血材料,解决了传统纱布在使用过程中吸血过多的问题。大量的动物实验结果表明,与传统医用纱布相比,新型止血纱布可显著降低失血量60%左右。此外,使用新型止血纱布在颈动脉出血情况下可使实验存活时间延长约40%。这种纱布有望为患者争取更多抢救时间。 根据以上文段,下列说法正确的是:
A.
新型止血纱布能够显著降低患者的死亡率
B.
传统医用纱布会导致颈动脉出血的死亡速度加快
C.
传统医用纱布通过大量吸收血液使伤口的血液流出速度减慢
D.
新型止血纱布可解决传统纱布在使用过程中吸血过多的问题
