Hello; if you had surgery today; its recommended that you communicate any doubt to your treating phisician and follow his/her indication during immediate postoperative time.
Many surgeons leave the incisions open after they do liposculpting of a body area. The combination of the fluid used during the surgery and some blood causes a lot of blood stained leakage after surgery. Typically this is normal, though, if there are also clots in the drainage i get more concerned. Stay in touch with your surgeon over these concerns, as I am sure his or her experience will help reassure you in your care.
It's normal to have the incisions stay open after a liposuction procedure in order for the tumescent fluid to egress out with time. It you have frank bleeding seek help immediately. Please follow up with your doctor as these issues require the attention of a plastic surgeon.
