What does the phrase "advance the drain 1 inch" mean?

The phrase "advance the drain 1 inch" refers to the action of pulling the drain out 1 inch. In medical or surgical contexts, particularly in procedures involving drains, advancing typically means to move the drain along its existing path, which could imply drawing it back slightly. The terminology used suggests that one should extend or retract the drain along its length, rather than pushing it deeper or making any modifications to the drain itself.

This action may be related to ensuring proper drainage, avoiding blockage, or preventing discomfort for the patient. It’s essential to understand that the phrase is about adjusting the positioning of the drain rather than increasing its size, securing it, or deepening its placement.
