摘要：目的 观察冠状动脉介入手术前禁食时间的长短对并发症的影响.方法 采用随机分组的方法,将656例择期介入手术的患者分为A、B两组,A组上午手术者术前晚正常进食,次日早餐进半流质饮食,下午手术者早餐正常进食水,午餐进半流质饮食,进食量为平日食量的80%左右,术后再让患者进食水.B组上午手术者术前晚正常进食,次日早餐禁食水,下午手术者术前早餐正常进食,中午禁食水,术后均正常进食水.结果 A组术前平均禁食时间为(2.0±1.2)h,B组术前平均禁食时间(14.0±1.5)h,B组禁食时间明显长于A组,且B组并发症的发生明显高于A组.结论 行冠状动脉介入手术的患者,术前尽可能缩短禁食水时间,能有效减少并发症的发生. Abstract： Objective To obsereve the impact of the time of pre-operative non-fasting on its complicaions in cardiac catheterization. Methods Dividing 656 cases into group A and group B at random.In group A, the operative patients in the morning eat normal food the night before last, semifluid food at the second day breakfast. The operative patients in the afternoon eat normal food at amount.In group B, the operative patients in the morning eat normal food the night before last, non-fasting at the second day breakfast, the operative patients in the afternoon eat normal food at breakfast,non-fasting at lunch. Results The average time of non-fasting was (2.0±1.2) hours in group A, (14.0±1.5) hours in group B;the time of non-fasting in group B was longer than that in group A,and the complications increased obviously in group B. Conclusions Shortening the time of pre-operative non-fasting can reduce its complications in cardiac catheterization.
