In-office cosmetic surgery performed while the patient is under general anesthesia or in combination with other procedures poses a higher risk of complications than single procedures or those involving only local anesthetics, according to a study published in Dermatologic Surgery. In particular, liposuction posed a higher risk of death when the patient was under general anesthesia than when a local anesthesia was used, the study authors said. "Liposuction under general anesthesia accounted for 32% of cosmetic procedure-related deaths and 22% of all cosmetic procedure-related complications," they wrote.
