目的:观察逐级半卧位模式对急性心肌梗死早期患者胃肠道功能的影响。方法:选取2011年1月至2015年1月就诊于该院CCU的急性心梗患者84例,随机分为实验组、对照组各42例,对比两组患者住院第3 d的心功能情况、进食情况、进餐后30 min情况、矢气排放情况以及大便排放情况。结果:(1)两组患者进食情况比较:实验组平均进流食总量为(1620±210)ml明显高于对照组(1250±260)ml(P<0.05);(2)两组患者进餐后30 min情况比较:实验组在胃胀、肠蠕动方面均优于对照组(P<0.05);(3)两组患者矢气排放情况比较:实验组排放率为88.1%,对照组为69.0%,实验组明显高于对照组(P<0.05);(4)两组患者大便情况比较:实验组和对照组的排便率分别为83.3%、61.9%,前者明显高于后者(P<0.05);实验组的首次排便时间为(32.14±15.86)h,低于对照组的(35.57±14.72)h(P<0.05)。结论:逐级半卧位模式是安全有效的措施,可在不影响患者心功能的情况下,增强胃肠道蠕动功能,改善AMI早期患者胃肠道的不适症状。
Objective: To observe the effect of stepwise semi-recumbent pattern on gastrointestinal function in patients with early acute myocardial infarction. Methods: A total of 84 acute myocardial infarction patients admitted to CCU from January 2011 to January 2015 were randomly divided into experimental group (n = 42) and control group (n = 42). The cardiac function of the two groups were compared on the 3rd day of hospitalization, Eating conditions, 30 min after meal, vestibular emissions, and stool emissions. Results: (1) Compared with the control group (1220 ± 260) ml (P <0.05), the average feed intake of the experimental group was (1620 ± 210) ml; (2) (P <0.05). (3) Compared with the control group, the discharge rate of vestibular gas in experimental group was 88.1% and in control group was 69.0 %, The experimental group was significantly higher than the control group (P <0.05); (4) Comparison of stool between the two groups: the defecation rate of the experimental group and the control group were 83.3%, 61.9%, the former was significantly higher than the latter (P < 0.05). The first defecation time of the experimental group was (32.14 ± 15.86) h, which was lower than that of the control group (35.57 ± 14.72) h (P <0.05). Conclusion: The step-by-step semi-recumbent mode is a safe and effective measure to enhance the gastrointestinal motility and improve the gastrointestinal symptoms in patients with early AMI without affecting cardiac function.
