Sir:

In the May 2013 issue of Plastic and Reconstructive Surgery, Pace et al. presented an article that discussed local anesthetic use in liposuction.1 The article reviewed much of the existing literature and recommended modifying the current American Society of Plastic Surgeons Practice Advisory. In particular, the authors recommended restricting the use of bupivacaine in infiltrative solution because of its pharmacologic properties and higher propensity for cardiotoxicity when compared with lidocaine. However, none of the evidence presented by the authors included any clinical data on the patient safety impact of bupivacaine use in tumescent solution, and we believe that this issue deserves further discussion and study before such changes are made to the Practice Advisory.

The authors justify their recommendation by citing studies involving modalities where bupivacaine is injected directly and where toxicity resulting from accidental intravascular injection is more likely.2,3 In contrast, we believe that using bupivacaine in tumescent solution is more comparable to its use in pain infusion pumps, where it has an established track record of safety and efficacy. Pain infusion pumps have gained popularity in surgical practice as a means of limiting postoperative narcotic use, decreasing length of stay, and improving patient satisfaction.4 There have been no reports in the literature of cardiac adverse events related to this modality.

Furthermore, newer bupivacaine equivalents, such as ropivacaine, are now available to reduce the likelihood of cardiotoxicity while maintaining the advantages of bupivacaine’s longer duration of action. Given preliminary results suggesting that bupivacaine may offer superior postoperative pain control where liposuction was combined with abdominoplasty,5 we believe that proper clinical studies should be performed evaluating bupivacaine and its equivalents in tumescent solutions before rendering judgment about their role in liposuction.

Practice guidelines should be made based on the best possible evidence. We agree with the authors on the necessity for caution when using bupivacaine in tumescent liposuction; however, we respectfully submit that the evidence currently does not conclusively support their recommendation to restrict its use.

GUIDELINES

Letters to the Editor, discussing material recently published in the Journal, are welcome. They will have the best chance of acceptance if they are received within 8 weeks of an article’s publication. Letters to the Editor may be published with a response from the authors of the article being discussed. Discussions beyond the initial letter and response will not be published. Letters submitted pertaining to published Discussions of articles will not be printed. Letters to the Editor are not usually peer reviewed, but the Journal may invite replies from the authors of the original publication. All Letters are published at the discretion of the Editor.

Letters submitted should pose a specific question that clarifies a point that either was not made in the article or was unclear, and therefore a response from the corresponding author of the article is requested.

Authors will be listed in the order in which they appear in the submission. Letters should be submitted electronically via PRS’ enkwell, at www.editorialmanager.com/prs/.

We reserve the right to edit Letters to meet requirements of space and format. Any financial interests relevant to the content of the correspondence must be disclosed. Submission of a Letter constitutes permission for the American Society of Plastic Surgeons and its licensees and asignees to publish it in the Journal and in any other form or medium.
