Efficacy of an aid (gastric tube insertion guide) for oral insertion of a gastric tube: a randomized controlled trial.

PURPOSE: Insertion of a gastric tube orally may be more difficult than its insertion nasally, and thus, any aid to facilitate its insertion may be useful. Gastric tube insertion guide (Fuji Medical Corporation, Tokyo, Japan) has recently become commercially available. We felt that this device might be useful in facilitating oral insertion of a gastric tube, but there has been no formal study assessing its efficacy. The main aim of this study was to assess whether or not this "tube guide" would facilitate insertion of an orogastric tube. METHODS: As a randomized controlled clinical study, we planned to study 40 patients, to assess the hypothesis that the success rate of insertion of an orogastric tube would be higher with the use of the "tube guide" than without. Patients were recruited when they were 20 years old, or older, and allocated randomly to one of two groups (20 people each group). In one group, the conventional "blind" insertion method was used and in the other group the "tube guide" insertion method. RESULTS: The success rate was significantly higher for the "tube guide" method than the "blind" insertion method (P = 0.0012, 95% CI for difference: 23-67%). CONCLUSION: We have shown that the use of the gastric tube insertion guide® facilitates insertion of an orogastric tube.

Efficacy of a gastric tube insertion guide for insertion of a nasogastric tube: a prospective, randomized controlled clinical study.

PURPOSE: We studied whether a newly available gastric tube insertion guide (Fuji Medical, Tokyo, Japan) was effective in insertion of a nasogastric tube. METHODS: Sixty anesthetized patients were randomly allocated to three groups, and we attempted to insert a nasogastric tube with a blind technique (Group B), with the lateral neck pressure (Group L), or with the tube guide (Group G). If the insertion failed in Group B or L, its insertion was attempted with the tube guide. Primary outcome measure was the insertion success rate within 300 s. RESULTS: The success rate in Group G (19 of 20 patients) was significantly higher than Group L (13 of 20 patients) (P = 0.04; 95% confidence intervals for difference: 16-44%), and than Group B (11 of 19 patients) (P = 0.008; 23-50%). In the 15 patients of Groups B and L, in whom insertion had failed, insertion with the tube guide was successful in 14 patients. There was no significant difference in insertion time between the groups, but in patients in whom insertion was successful, it was significantly longer in Group G (median of 147 s) than in Group L (66 s) (P < 0.01) and Group B (46 s) (P < 0.01). Minor complications occurred in 2 patients in Group B, 1 in Group L, and 5 in Group G (P > 0.05). CONCLUSION: We conclude that the gastric tube insertion guide (Fuji Medical, Tokyo, Japan) may be useful when the conventional method of insertion has failed.
