Understanding and controlling the variables for stromal vascular fraction therapy

Table 3 Anesthesia options for stromal vascular fraction isolation procedures

Anesthesia type	Description	Application in SVF isolation
Local anesthesia[39]	Involves injecting anesthetic agents like lidocaine at the harvest site. Patients remain conscious and have minimal systemic side effects	Preferred for small-scale SVF isolation; ensures patient comfort and cooperation
Tumescent anesthesia[40]	Diluted lidocaine with epinephrine and saline is injected to anesthetize, minimize bleeding, and ease tissue harvest	Common in liposuction to obtain adipose tissue; provides extended anesthesia and vasoconstriction
General anesthesia[41-43]	Induces complete sedation and unconsciousness, used in comprehensive surgical settings	Rarely used solely for SVF isolation; considered if combined with other surgical interventions
