Digital (Two-finger) versus Video Laryngoscopy for Nasogastric Tube Insertion in Intubated Patients; a Clinical Trial Study.

Introduction: Performing Nasogastric Tube (NGT) insertion is very challenging in anesthetized and intubated patients. The current study aimed at comparing Digital (two-finger) and Video Laryngoscopy methods for NGT insertion in the mentioned patients.

Methods: The present single-blind clinical trial was performed on 76 intubated patients, who were randomly divided into two groups. Groups A and B underwent Video Laryngoscopy and Digital (two-finger) methods, respectively. Then, the success rate, the number of attempts to insert NGT, duration of insertion, hemodynamic parameters, and patients' satisfaction level were recorded and compared between groups.

Results: The mean duration of NGT insertion in group A was significantly higher than that of group B (19.07 ± 2.07 vs 11.53 ± 2.16 seconds; P value=0.001). The success rate was higher in group B (94.7% vs. 78.9%; P value=0.042). Considering the interfering factors such as patients' body mass index (BMI), the odds of success in group B was reported to be 8.49 times higher than that of group A (P value =0.028).

Conclusion: Digital method can be considered as a safe and appropriate method of NGT insertion for intubated cases with high success rate and speed of performance.
