Drain fluid appearance can change during the postoperative course. Usually, the fluid doesn't have much of a smell, so any changes would be a concern.Please see your surgeon ASAP and review these changes with him/her. The sooner, the better.
Thanks for your inquiry, but honestly without examining you it is impossible to advise you and tell you if you should be concerned. Please call your surgeon to discuss, good luck.
Thank you for your question and congratulations on your surgery. Drainage can develop different odors and it is important to note any changes to its character. Since this has been a change in your recovery it is best to reach out to your surgeon's office to ensure that all is well, but as long as you are not seeing a change in your physical appearance, the smell is not malodorous and the consistency of the drainage is thin, all is likely well. Hope this helps.
