摘要 AIM: To investigate the effect of percutaneous endoscopic gastrostomy (PEG) on gastroesophageal reflux (GER) in mechanically-ventilated patients. METHODS : In a prospective, randomized, controlled study 36 patients with recurrent or persistent ventilatorassociated pneumonia (VAP) and GER 〉 6% were divided into PEG group (n=16) or non-PEG group (n = 20). Another 11 ventilated patients without reflux (GER 〈 3%) served as control group. Esophageal pH-metry was performed by the "pull through" method at baseline, 2 and 7 d after PEG. Patients were strictly followed up for semi-recumbent position and control of gastric nutrient residue. RESULTS: A significant decrease of median (range) reflux was observed in PEG group from 7.8 (6.2-15.6) at baseline to 2.7 (0-10.4) on d 7 post-gastrostomy (P 〈 0.01), while the reflux increased from 9 (6.2-22) to 10.8 (6.3-36.6) (P〈 0.01) in non-PEG group. A significant correlation between GER (%) and the stay of nasogastric tube was detected (r= 0.56, P〈 0.01). CONCLUSION: Gastrostomy when combined with semi- recumbent position and absence of nutrient gastric residue reduces the gastroesophageal reflux in ventilated patients. 瞄准:在机械地通气的病人在胃的食道的倒流(GER ) 上调查经皮的内视镜的胃造口术(木钉) 的效果。方法:在未来的、使随机化的、控制研究有周期性或坚持的联系通风机的肺病(VAP ) 和 GER > 的 36 个病人 6% 被划分成木钉组(n = 16 ) 或非木钉组(n = 20 ) 。11 通气了没有倒流的病人(GER <3%) 用作控制组。食道的 pH-metry 被执行由在基线“渡过”方法,在木钉以后的 2 和 7 d。病人们严格地被跟随在上面为胃的滋养的残余的半侧卧的位置和控制。结果:median (范围)的重要减少倒流从 7.8 在木钉组被观察( 6.2 - 15.6 )在到 2.7 的基线( 0 - 10.4 )在 d 上 7 post-gastrostomy ( P < 0.01 ),当倒流从 9 增加了时( 6.2 - 22 )到 10.8 ( 6.3 - 36.6 )( P < 0.01 )在非木钉组。在 GER (%) 和 nasogastric 试管的停留之间的重要关联被检测(r = 0.56, P < 0.01 ) 。结论:胃造口术什么时候与滋养的胃的残余的半侧卧的位置和缺席结合了,在通气病人减少胃的食道的倒流。
