OBJECTIVE: To evaluate whether a simple aspiration test can be used to accurately confirm the correct placement of fine-bore feeding tubes in the oesophagus and prevent their inadvertent placement in the bronchial tree.
DESIGN: We conducted an ethically approved, randomised, blinded trial to assess the accuracy of a simple aspiration test to differentiate between oesophageal and tracheal placement.
SETTING: A tertiary referral cardiothoracic surgical unit.
PATIENTS AND PARTICIPANTS: Twenty patients under-going elective cardiac surgery.
INTERVENTION: Once anesthetised, a fine-bore feeding tube was inserted into the oesophagus or trachea and a researcher, blinded to the position, then performed the test. This involved attempted aspiration of > or =10 ml of air before and after insufflation of 10 ml of air and comparison with capnography, a test that has been shown to be highly sensitive and specific.
MEASUREMENTS AND RESULTS: With this small number of patients, the test accurately differentiated between ten oesophageal and ten tracheal placements.
CONCLUSIONS: A simple aspiration test could be a useful adjunct to prevent inadvertent bronchial placement of fine-bore feeding tubes. Careful attention must be paid to the technique to ensure that no false positives occur.
