Clogged drain from tummy tuck. How can I unclog it?

Contact your surgeon regarding your drain.  Is it still maintaining suction (remains in the collapsed position when squeezed)? Milking the tubing often clears it for a more accurate reading of the output and helps to move small clots into the collection bulb, but it is unusual that this would clog the drain.  More investigation is needed as to the cause that the output has ceased.

You will not be able to unclog a drain that is totally clogged.  The "milking" helps to remove very small clots.  The amount of drainage you've had is unusual for a tummy tuck without liposuction and without use of tumescent fluid.  Call  your surgeon for an appointment to check your drain.
