摘要目的 探讨不同鼻饲间隔时间对昏迷气管切开患者鼻饲后胃内容物的反流的影响.方法 将38例昏迷气管切开的患者分别以2、3、4 h的间隔时间进行鼻饲,每例患者每种鼻饲间隔时间各1 d,直至每种间隔时间的鼻饲次数为760次,观察每次鼻饲后反流的发生.结果 胃内容物反流的发生率分别为:A(2 h 1次):15.66%,B(3 h 1次):10.66%, C(4 h 1次):8.16%.分别进行两两比较发现:A与B、C比较差异均有统计学意义(P<0.01); B与C比较差异无统计学意义(P>0.05).结论 昏迷气管切开患者鼻饲间隔时间为3、4 h时反流发生率较低.

abstractsObjective To explore the effect of different interval time of naso-feeding on backstreaming of gastric contents in tracheotomy patients with coma. Methods Thrity-eight trachetomy patients with coma were given naso-feeding with different interval time as: A:2 h; B:3 h; C:4 h,each interval time was adapted each day to each patient,until the totle times of each naso-feeding with different interval time up to 760, observed backstreaming happenning after naso-feeding. Results The rate of backstreaming was A:15.66% B:10.66% C:8.16%, respectively, then compared between each other.It showed that B and C had very significient differents compared with A(P<0.01), however C had no significient different compared with B(P>0.05). Conclusions Interval time of naso-feeding of 3 h or 4 h lead to a lower rate on backstreaking of gastric contents in tracheotomy patient with coma.
