Thermal imaging detects infrared radiation from an object, producing a thermogram that can be interpreted as a surrogate marker for cutaneous blood flow. To date, high-resolution cameras typically cost tens of thousands of dollars. The FLIR ONE is a smartphone-compatible miniature thermal imaging camera that currently retails at under $200. In a proof-of-concept study, patients and healthy volunteers were assessed with thermal imaging for (1) detecting and mapping perforators, (2) defining perforasomes, and (3) monitoring free flaps. Preoperative, intraoperative, and postoperative thermograms can assist in the planning, execution, and monitoring of free flaps, and the FLIR ONE provides a low-cost adjunct that could be applied to other areas of burns and plastic surgery.

Background Evidence of the benefit of dilute epinephrine infiltration before reduction mammaplasty is provided by several controlled trials. Despite variation in operative technique and data collection, a reduction in intraoperative blood loss has been shown. The aim of this review of the literature is to weigh the available evidence with respect to reducing blood loss during surgery and other outcome measures such as postoperative drainage. Methods Two researchers independently selected articles for review, and data were extracted from each primary article and used for statistical and descriptive comparisons. Results A meta-analysis of operative blood loss showed a highly significant drop in operative blood loss in breasts infiltrated with epinephrine and a reduction in the need for blood transfusion. Operative time, postoperative drainage, and complications were not significantly affected by epinephrine infiltration. Conclusion The authors' recommendation would be for the use of dilute epinephrine infiltration before reduction mammaplasty.
