About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • patient who is scheduled for elective surgery under general anaesthesia requiring NGT insertion
  • aged 20 to 70 years old
  • with normal airway (Commack Lehane 1 or 2) and neck movements.

Exclusion criteria

  • Patient who has nasal stenosis, nasal septal deviation, upper airway deformity, base of skull fracture, oesophageal disorders, coagulopathy, and pregnant.

Treatment and study plan

Conventional Technique

Other

Nasogastric tube insertion with patient's head in neutral position

Contralateral cricothyroid pressure

Other

Cricothyroid pressure is applied externally in the contralateral direction of selected nostril before nasogastric insertion.

Ipsilateral head turning

Other

Patient's head is turned to the ipsilateral side of the selected nostril before nasogastric tube insertion.

Primary outcomes

  1. Overall success rate

    Time frame: At induction of general anesthesia

    Percentage

Secondary outcomes

  1. First attempt success rate

    Time frame: At induction of general anesthesia

    Percentage

  2. Time taken to successful nasogastric tube placement

    Time frame: 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.
