Introduction: Data using ultrasonography to confirm correct position of the gastric tube is heterogeneous in approach sites, combination exams, and methodology.

Aim: Find the best strategy to confirm gastric tube placement to avoid immediate complication.

Method: A randomized controlled trial was initiated to compare ultrasonography and standard routine method, using non-inferiority design. The study will be conducted in one medical ICU with 59 beds at a medical center. The primary outcome is the correct rate as comparing with the chest radiography in each group. Total 190 patients is needed with estimated 10% drop-out rate.
