Endotracheal tube-assisted orogastric tube insertion in intubated patients in an ED.

BACKGROUND AND AIMS: Inserting a nasogastric tube (NGT) in intubated patients may be difficult because they cannot follow swallowing instructions, resulting in a high rate of first-attempt failure. We introduce a simple technique for inserting an orogastric tube in an emergency department (ED).

METHODS: Fifty-six patients in the ED, who were intubated and required NGT insertion, were randomly allocated to 2 groups. We inserted the NGT using a conventional technique from the nostril (control group) and an endotracheal tube (ET)-assisted technique from the mouth (ET group). The procedures' success rate, insertion duration, and complications were compared between the groups.

RESULTS: There was a significantly higher overall success rate in the ET group than the control group (100% vs 64%, P<.001). Endotracheal tube group showed 100% first-attempt success rate, but 50% of the control group failed at first attempt. Mean duration of the first trial was not significantly different between the ET and control groups (58.0±16.9 vs 57.3±29.5 seconds, P=.903), but total time for successful insertion was longer in the control group than the ET group (58.0±16.9 vs 111.7±74.5 seconds, P<.001). There was less NGT kinking and more mucosal bleeding in the ET group than in the control group (0% vs 16%, P=.019; 16% vs 7%, P=.225, respectively).

CONCLUSION: Endotracheal tube-assisted orogastric tube insertion technique showed a higher rate of successful insertion and shorter total duration. With this result, ET-assisted orogastric tube insertion would be useful in ED.
