Workup

Laboratory Studies

See the list below:

  • Basic blood chemistry evaluations (eg, CBC count, prothrombin time/activated partial thromboplastin time) and a sequential multiple analysis of 20 chemical constituents should be performed so that any preexisting renal, hematologic, or hepatic problems can be recognized and accounted for before the procedure.
Next:

Other Tests

See the list below:

  • A thorough preoperative evaluation should be performed to address any medical condition and determine the patient's ability to safely undergo a surgical procedure.
  • An ECG should be performed if indicated on thorough preoperative evaluation.

Histologic Findings

In 2000, Lawrence and Cox examined histologic specimens from 19 patients who underwent external ultrasound-assisted liposuction (UAL) and found that the fat membranes were not disrupted and the adipocyte lobules were intact. [14] No differences were noted between the tumescent liposuction aspirated fat pretreated with external ultrasound and that of control samples.

In 2008, Ferraro et al demonstrated that, at 1 MHz, external UAL did not alter the cellular architecture of fat cells, but, at 2 and 3 MHz, massive adipose cellular destruction ensued. [5]
