三种不同鼻饲泵注方式对ICU危重患者胃肠道并发症的影响

Influence about complications of gastrointestinal tract among ICU patients by three methods of nasal feeding pump

目的：探讨3种不同鼻饲方式对ICU危重患者胃肠道并发症的影响，从而为ICU患者选择合理的鼻饲泵注方式提供指导。方法将120例ICU危重患者按照随机数字表法分为A组（持续泵6h间断2h，每天分3个时间单元）、B组（持续24h泵入组）和C组（持续泵2h间断1h，每天分8个时间单元），观察3种不同泵注方式对ICU患者胃肠道并发症的影响。结果3组泵注方式在腹泻和便秘发生率上比较差异均无统计学意义（P＞0.05），B组胃潴留发生率均明显高于A组和C组，差异均有统计学意义（χ2=8.936，P＜0.05），A组和C组比较，差异无统计学意义（P＞0.05）。结论持续24 h泵注方式在胃潴留方面稍差于另外2种泵注方式，结合ICU三班工作制和喂养次数比较，持续6 h，间断2 h，分3个时间单元泵注方式更适合ICU患者。

Objective To discuss the influence about three kinds of nasal feeding methods on ICU critical patients with gastrointestinal complications, thus providing guidance for ICU patients to choose reasonable way of nasal feeding pump injection. Methods 120 ICU patients were randomly assigned into three groups, which is the continuous 6-hour and intermittent 2-hour every three time pump group and continuous 24-hours pump group and intermittent 24-hour(continuous 2-hour and intermittent 1-hour every eight time units)pump group ,each group has 40 cases. To observe the the influence about three different way of nasogastric on ICU critical patients with gastrointestinal complications. Results The incidence of diarrhea and constipation among the three groups was not statistically significant (P>0.05) . The gastric retention rate of the continuous 24-hour pump group was significantly higher than that of the continuous 6-hour and intermittent 2-hour pump group and the intermittent 24-hour pump group, the differences were statistically significant (P < 0.05). There was no statistically significant difference between the continuous 6-hour and intermittent 2-hour pump group and the intermittent 24-hour pump group, (P > 0.05). Conclusions The continuous 24-hour pump group in gastric retention was slightly worse than the other two pump way. Compared with ICU class three a week and feeding times , the continuous 6-hour and intermittent 2-hour pump method is more suitable for ICU patients.
