Regional Anesthetic Blocks in Plastic Surgery Using Portable Ultrasound: A Simplified Approach.

ABSTRACT

BACKGROUND: With the introduction of latest generation ultrasound technology and its easy availability and portability, regional anesthetic blocks, which were formally in the domain of anesthesiologists, have now become available to practicing plastic surgeons. Enhanced Recovery After Surgery protocols for other specialties such as orthopedics and colorectal surgery have incorporated regional anesthetic blocks. These regional blocks have been shown to be effective in improving the patient comfort and experience and decreasing reliance on opioid medications. METHODS: Patients scheduled for elective plastic surgery received PEC-1, serratus anterior plane, or transversus abdominis plane blocks as indicated for the proposed procedure. All blocks were performed under ultrasound guidance using the Philips Lumify system with the linear array 12-4 probe by the operating surgeon. RESULTS: A total of 83 patients received regional anesthetic blocks by the senior author. Thirty-three patients undergoing cosmetic breast augmentation or implant-based breast reconstruction received the PEC-1 and the serratus anterior plane blocks after the induction of anesthesia but before the prep and drape. Fifty patients undergoing either abdominoplasty or deep inferior epigastric perforator flap reconstruction received intraoperative transversus abdominis plane blocks. Anatomic planes were clearly visualized with this new ultrasound technology. Patients experienced good to excellent analgesia with less reliance on opioid medications and decreased need for refills. For hospitalized patients, length of stay in some cases was decreased up to 1 day, and PCA pumps were eliminated. There were no complications or adverse sequelae observed in any of these patients related to the regional blocks. CONCLUSIONS: Incorporation of these known regional anesthetic techniques in this single-surgeon experience seems to confirm reports of effectiveness in the anesthesia literature and may be of benefit to a wide range of plastic surgery patients.
