• Conditions: General Anesthesia
• Interventions: Other: Contralateral cricothyroid pressure; Other: Ipsilateral head turning; Other: Conventional technique

• Registration Number: NCT03492008

Brief Summary

This study compares two modified techniques(contralateral cricothyroid pressure and ipsilateral head turning technique) of nasogastric tube insertion in anesthetized and intubated patients with the conventional technique.

Detailed Description

The insertion of nasogastric tube in anesthetized, paralysed and intubated unconscious patients may be difficult, with a reported failure rate of nearly 50% on the first attempt, with the head in neutral position there are many different maneuvers to facilitate the insertion of nasogastric tube published.

Our hypothesis is that contralateral cricothyroid pressure to the selected nostril for nasogastric tube insertion will be able to avoid the difficulty.

Therefore we are going to compare this technique with the conventional technique (head in neutral position) with lateral head turning group and contralateral cricothyroid pressure group We hope that the contralateral cricothyroid pressure will increase the success rate, as this will be helpful in intubated patients with neck pathology.

Primary Outcome Measures

Name	Time	Method
Overall success rate	At induction of general anesthesia	Percentage

Secondary Outcome Measures

Name	Time	Method
First attempt success rate	At induction of general anesthesia	Percentage
Time taken to successful nasogastric tube placement	At induction of general anesthesia	Procedure start time is defined as the time when the nasogastric tube is inserted through the nostril. The procedure end time is defined as the time of successful insertion and confirmed NGT placement or the time after two failed attempts. The outcome is measured in second.
