The influence of the weight of the duodenal tube tip on its entrance time

  • 8 Accesses

  • 3 Citations


  1. 1.

    A successful intubation of the duodenum was accomplished in a two-hour period with any one of four tubes used, in about 90% of the attempts.

  2. 2.

    A lead weighted tip appears to hasten entrance into the duodenum. This, however, has not been determined beyond doubt.

  3. 3.

    Increasing the weight of the tip from 69 grains (Twiss Tube) to 150 grains (Moses Einhorn Tube 1938) does not appear to accelerate its passage, or increase the percentage of successes.

Note: I am grateful to Elsa Nussbaumer, R.N., for her technical assistance.
