Anesthesia, General, Nasogastric Tube, Nasopharyngeal Airway
Conditions
Brief summary
Nasogastric tube placement is essential for various surgery and critically ill patients. However, NG tube insertion in anesthetized, paralyzed, and intubated or unconscious patients may be difficult, with reported success rate less 50% on the first attempt without any auxiliary devices. Endotracheal tube intubation narrow the space of oropharynx and hypopharynx. Loss ability to swallow and tongue drop also made the NG tube coil in the mouth easily. Investigators assume nasopharyngeal airway can facilitate NG tube insertion by opening a channel from nostril to epiglottis and reduce complications by protecting nasal cavity while inserting NG.
Interventions
PROCEDUREWith nasopharyngeal airway
Nasopharyngeal airway is previously inserted into selected nostril. NG tube is properly lubricated and placed through Nasopharyngeal airway.
PROCEDUREWithout nasopharyngeal airway
NG tube is properly lubricated and placed into selected nostril
