Background And ObjectivesSeveral techniques are available to facilitate nasogastric (NG) tube insertion with or without using other instruments to guide the NG tube to the stomach. This study aimed to determine the success rate and time required for inserting NG tube by 2 non-instrumental methods of NG tube insertion and compare the findings with the common method of NG tube insertion.Design And SettingsA prospective randomized, controlled clinical trial carried out at Chang Gung Memorial Hospital in Taiwan.Subjects And MethodsA total of 150 patients were randomized into 3 groups: control group, neck flexion with lateral pressure group, and lifting of the larynx group. The number of attempted insertions, success rate, duration of insertion, and various complications were recorded.ResultsBoth neck flexion with lateral pressure and lifting of the thyroid cartilage techniques had high success rates; however, the time required to insert the NG tube was shortest in the thyroid cartilage lifting group.ConclusionNeck flexion with lateral pressure and lifting of the thyroid cartilage are convenient and reliable techniques for NG tube insertion without using any other instruments. Lifting of the thyroid cartilage had the highest success rate and was less time consuming than the other NG tube insertion techniques. Familiarization with the procedure influenced the success rate and the time required for insertion.
