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.
Interventions
Nasogastric tube insertion with patient's head in neutral position
OTHERContralateral cricothyroid pressure
Cricothyroid pressure is applied externally in the contralateral direction of selected nostril before nasogastric insertion.
OTHERIpsilateral head turning
Patient's head is turned to the ipsilateral side of the selected nostril before nasogastric tube insertion.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall success rate | At induction of general anesthesia | Percentage |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 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. |
