I would appreciate advice on NGT placement. On a previous shift I placed and NGT tube without difficulty, varified by asculation at the epigastrum and had clear gastric return. The ER doc then requested lavage for blood, which I did, lavaging 250 ml NS and suctioning same amount, no blood. Later the Pt went to CT and it was revealed that the NGT was in the proximal esophagus. How could I have better varified placement?
