Abstract

Intramuscular gluteal lipoinjection has become one of the most commonly used surgical procedures for achieving improvement in the gluteal contour; however, there are few studies that report and analyze the causes of secondary death from this surgical procedure.

Fat grafting: evidence-based review on autologous fat harvesting, processing, reinjection, and storage.

Phanette Gir, Spencer Brown, Georgette Oni … (2012)

Over the past 20 years, there has been a dramatic increase in the use of autologous fat grafting to treat volume and contour defects in aesthetic and reconstructive surgery. It is generally accepted that fat grafting is safe, with good patient satisfaction. However, there are many procedural variations, and in terms of objective clinical effectiveness, the major disadvantage of this technique remains the unpredictable fat resorption rates and subsequent adverse events. Because of the rapidly evolving nature of this procedure, this review article provides an update on previous reviews by looking at the current evidence base regarding fat graft techniques and their effect on clinical outcome. A systematic review of the scientific literature listed on PubMed was performed using 20 search terms focused on harvesting, processing, reinjection, and conservation of fat grafting. An evidence-based system was used to determine eligibility for clinical and preclinical studies. Thirty-seven articles were selected based on inclusion and exclusion criteria: five articles were clinical trials and 32 were experimental comparative studies examining human fat grafting. This systematic review revealed a lack of high-quality data despite the increase in fat grafting over the past 20 years. At present, there is no evidence that supports specific procedural standardization. Evidence-based studies that incorporate randomized controlled, prospective, multicenter trials are required to understand which factors influence positive fat grafting clinical outcomes.

Deaths related to liposuction.

Joel Hoffman, Raj Rao, S. Ely (1999)

The technique of tumescent liposuction involves the subcutaneous infusion of a solution containing lidocaine, followed by the aspiration of fat through microcannulas. Although the recommended doses of lidocaine are as high as 55 mg per kilogram of body weight, few safety data are available. Since reporting of adverse events associated with tumescent liposuction is not mandatory, the incidence of complications and deaths is unknown. We identified 5 deaths after tumescent liposuction among 48,527 deaths referred to the Office of Chief Medical Examiner of New York City between 1993 and 1998. The patients' records and postmortem examination results were reviewed to identify common contributory factors. The five patients had received lidocaine in doses ranging from 10 to 40 mg per kilogram. Other drugs, such as midazolam, were also administered. Three patients died as a result of precipitous intraoperative hypotension and bradycardia with no definitively identified cause. Postmortem blood lidocaine concentrations in two of the patients were 5.2 and 2 mg per liter. One patient died of fluid overload, and one died of deep venous thrombosis of calf veins with pulmonary thromboembolism after tumescent liposuction of the legs. Tumescent liposuction can be fatal, perhaps in part because of lidocaine toxicity or lidocaine-related drug interactions.
