To answer your question about Tumescent Liposuction without Tumescent fluid, it is necessary to clarify the term "Tumescent Liposuction." In the true meaning of the term, Tumescent Liposuction is liposuction performed by infusing a solution of dilute xylocaine (local anesthetic) and epinephrine (adrenalin) into the fatty tissue without any sedation or other type of anesthesia. The xylocaine provides the anesthesia and the epinephrine constricts the blood vessels, resulting in minimal blood loss and bruising.
In 1987, I published research about the blood loss that occurred using different liposuction techniques. The results and findings were the blood loss in any liposuction without Tumescent fluid was unacceptably high. In order to minimize the blood loss in liposuction, the surgeon must infiltrate a solution that contains epinephrine into the fat. Today, it is universally accepted that the safest way to perform liposuction requires infiltrating Tumescent fluid into the fat.
If the surgeon is using general anesthesia or epidural anesthesia, the primary role of the fluid is to prevent bleeding, not to provide anesthesia. The anesthesia ( pain relief) comes from the general or the epidural.
If the surgeon is using pure traditional Tumescent Anesthesia, the fluid provides the anesthesia and prevents blood loss.
Now, I can answer your question. If the anesthesia is pure traditional Tumescent, surgery beyond the fluid will hurt as the surgeon works in an unanesthetized area and you will have bleeding and bruising. If the primary anesthesia is general or epidural and the liposuction is performed beyond the limits of the infiltration, you will not feel anything (you are under anesthesia) but you will have excessive bleeding and bruising.
This was a great question. I hope my long answer covers your concerns.
