| Summary: | Background and Aims: Insertion of nasogastric tubes (NGTs) in anaesthetised, intubated patients with a conventional method is sometimes difficult. Different techniques of NGT insertion have been tried with varying degree of success. The aim of this prospective, randomised, open-label study was to evaluate three modified techniques of NGT insertion comparing with the conventional method in respect of success rate, time taken for insertion and the adverse events. Methods: In the operation theatre of general surgery, the patients were randomly allocated into four groups: Group C (control group, n = 54), Group W (ureteral guide wire group, n = 54), Group F (neck flexion with lateral pressure, n = 54) and Group R (reverse Sellick′s manoeuvre, n = 54). The number of attempts for successful NGT insertion, time taken for insertion and adverse events were noted. Results: All the three modified techniques were found more successful than the conventional method on the first attempt. The least time taken for insertion was noted in the reverse Sellick′s method. However, on intergroup analysis, neck flexion and reverse Sellick′s methods were comparable but significantly faster than the other two methods with respect to time taken for insertion. Conclusion: Reverse Sellick′s manoeuver, neck flexion with lateral neck pressure and guide wire-assisted techniques are all better alternatives to the conventional method for successful, quick and reliable NGT insertion with permissible adverse events in anaesthetised, intubated adult patients. Further studies after eliminating major limitations of the present study are warranted to establish the superiority of any one of these modified techniques.
