| 摘 要： | 目的探讨注气听诊法、pH试纸检测法判断外科重症患者床边放置鼻肠管的准确性及影响因素。方法采用标准操作流程为60例外科重症患者行床边放置鼻肠管,同时分别用注气听诊法、pH试纸检测法进行床边判定,记录判定结果;放置结束每例患者再采用影像学方法作为判定鼻肠管位置金标准。检测质子泵抑制剂类药物的使用对pH试纸检测法判定准确率的影响。结果累计为60例患者放置鼻肠管,置管成功38例,失败22例。注气听诊法及pH试纸检测法均提示在位组置管成功率显著高于单项提示组和未提示组,差异有统计学意义(P<0.01);此外,质子泵抑制剂的使用显著降低pH试纸检测法的准确性(P<0.01)。结论行床边盲放鼻肠管时,当且仅当注气听诊法、pH试纸检测法均提示在位才有较高的置管成功率;使用质子泵抑制剂显著降低了pH试纸检测法准确性。

Evaluation of gas-stimulated auscultation and pH test during the bedside placement of nasointestinal tube in surgical critically ill patients |

| Abstract: | Objective To investigate the accuracy and influencing factors of gas-stimulated auscultation and pH test during the bedside placement of nasointestinal tube in surgical critically ill patients.Methods The nasointestinal tubes were placed in 60 surgical critically ill patients according to the standard bedside placement procedure.At the same time,the position of each tube was assessed by gas-stimulated auscultation and pH test,all the results were recorded.Radiology method was adopted as the gold standard for evaluating the nasoenteral postion after the placement.Results A total of 60 patients were placed the nasointestinal tubes,38 cases succeed,and 22 cases failed.The combination of both positive gas-stimulated auscultation and pH test demonstrate a higher rate of successful tube placement than the other three groups(P<0.01).In addition,the use of proton pump inhibitors significantly reduced the accuracy of the pH strip assay (P<0.01).Conclusions A high success rate can be achieved only when the gas-stimulated auscultation and pH test both prompt in place during the bedside placement of nasointestinal tube.The use of proton pump inhibitors significantly decreases the accuracy of the pH detection. |
