When guidelines for tumescent surgery are followed, treatment of patients with a broad range of concerns can be extremely effective. Whether its use is as a primary technique as in liposuction, or as an adjunct to another procedure such as reduction mammoplasty, the effects of reduced blood loss, pain control, and fluid management make it a powerful tool for the surgeon. Constant awareness of volumes infiltrated and aspirated, as well as the patient’s clinical status, are critical in the safe delivery of tumescent surgery.
