Abstract

Objective

Nasogastric tube (NGT) insertion in anesthetized and intubated patients can be challenging, even for experienced anesthesiologists. Various techniques have been proposed to facilitate NGT insertion in these patients. This study aimed to compare the success rate and time required for NGT insertion between GlideScope™ visualization and neck flexion, with lateral neck pressure techniques.

Material and methods

This randomized clinical trial was performed at a teaching hospital on 86 adult patients undergoing abdominal surgery, under relaxant general anesthesia, who required intraoperative NGT insertion. The patients were randomized into two groups, the GlideScope™ group (group G) and the neck flexion with lateral neck pressure group (group F). The success rate of the first and second attempts, duration of insertion, and complications were recorded.

Results

The total success rate was 79.1% in group G, compared with 76.7% in group F (P = 1). The median time required for NGT insertion was significantly longer in group G, for both first and second attempts (97 vs 42 s P < 0.001) and (70 vs 48.5 s P = 0.015), respectively. Complications were reported in 23 patients (53.5%) in group G and 13 patients (30.2%) in group F. Bleeding and kinking were the most common complications for both techniques.

Conclusion

Using GlideScope™ visualization to facilitate NGT insertion was comparable to neck flexion with lateral neck pressure technique, in the degree of success rates of insertion. Although complications were not statistically significant between groups, neck flexion with lateral neck pressure technique was significantly less time-consuming for both first and second attempts.
