Can draining 150cc dark red blood after 10 days Tummy tuck surgery be a sign of infection?

 It is normal to have drainage after a tummy tuck.   That's why most surgeons place drainage tubes.   Very dark drainage may indicate that you had some bleeding below your abdominal flap which is now "organizing" and coming to your tubes.  The blood initially forms a clot which then breaks down into a liquid that can come out through your tubes.  Make sure that your surgeon understands how much drainage you're still getting. I would not recommend pulling your drainage tubes out if you're still getting 150 mL a day.  Best wishes to you!

hard to say without seeing you, but I would not pull the drain if you are still draining 150cc a day.  this is not a sign of infection

Bloody drainage after a tummy tuck is not uncommon and will continue to decrease in volume as your recovery continues. It is not typically a sign of infection. Ideally, drainage should be less that 30cc/4hours to have the drains removed. Please make sure your surgeon knows the exact amount prior to removing the drains. It is disappointing to have to have them replaced. Good luck.
