What type of fluid is typically injected as tumescent fluid before suction liposuction?

Tumescent fluid is typically a solution that includes a mixture of normal saline, local anesthetics (like lidocaine), and epinephrine. The purpose of injecting tumescent fluid before suction liposuction is to induce a state of tumescence, where the adipose tissue becomes swollen and firm, making it easier to aspirate the fat during the procedure. Normal saline acts as a carrier for the local anesthetics and helps in the infiltration process.

While lactated Ringer's solution and glucose solutions are used in medical settings for different reasons, they are not typical components of tumescent fluid for liposuction. Heparin solution is an anticoagulant and not used for this purpose, as tumescent fluid requires a combination that facilitates both anesthesia and fluid management without specifically altering coagulation. Thus, normal saline is the most appropriate choice for creating the effective tumescent solution necessary for suction liposuction.
