Practical Review of Abdominal and Breast Regional Analgesia for Plastic Surgeons: Evidence and Techniques

Liposomal Bupivacaine Analgesia in Deep Inferior Epigastric Perforator Flap Breast Reconstruction: A Retrospective Cohort Study

Background

Liposomal bupivacaine (LB) can be used for postsurgical analgesia after breast reconstruction. We examined real-world clinical and economic benefits of LB versus bupivacaine after deep inferior epigastric perforator (DIEP) flap breast reconstruction.

Methods

This retrospective cohort study used the IQVIA claims databases to identify patients undergoing primary DIEP flap breast reconstruction in 2016-2019. Patients receiving LB and those receiving bupivacaine were compared to assess opioid utilization in morphine milligram equivalents (MMEs) and healthcare resource utilization during perioperative (2 weeks before surgery to 2 weeks after discharge) and 6-month postdischarge periods. A generalized linear mixed-effects model and inverse probability of treatment weighting method were performed.

Results

Weighted baseline characteristics were similar between cohorts (LB, n = 669; bupivacaine, n = 348). The LB cohort received significantly fewer mean MMEs versus the bupivacaine cohort during the perioperative (395 versus 512 MMEs; rate ratio [RR], 0.771 [95% confidence interval (CI), 0.677-0.879]; P = 0.0001), 72 hours after surgery (63 versus 140 MMEs; RR, 0.449 [95% CI, 0.347-0.581]; P < 0.0001), and inpatient (154 versus 303 MMEs; RR, 0.508 [95% CI, 0.411-0.629]; P < 0.0001) periods; postdischarge filled opioid prescriptions were comparable. The LB cohort was less likely to have all-cause inpatient readmission (odds ratio, 0.670 [95% CI, 0.452-0.993]; P = 0.046) and outpatient clinic/office visits (odds ratio, 0.885 [95% CI, 0.785-0.999]; P = 0.048) 3 months after discharge than the bupivacaine cohort; other all-cause healthcare resource utilization outcomes were not different.

Conclusions

LB was associated with fewer perioperative MMEs and all-cause 3-month inpatient readmissions and outpatient clinic/office visits than bupivacaine in patients undergoing DIEP flap breast reconstruction.

Reducing Disparities: Regional Anesthesia Blocks for Mastectomy with Reconstruction Within Standardized Regional Anesthesia Pathways

BACKGROUND

Recent data suggest disparities in receipt of regional anesthesia prior to breast reconstruction. We aimed to understand factors associated with block receipt for mastectomy with immediate tissue expander (TE) reconstruction in a high-volume ambulatory surgery practice with standardized regional anesthesia pathways.

PATIENTS AND METHODS

Patients who underwent mastectomy with immediate TE reconstruction from 2017 to 2022 were included. All patients were considered eligible for and were offered preoperative nerve blocks as part of routine anesthesia care. Interpreters were used for non-English speaking patients. Patients who declined a block were compared with those who opted for the procedure.

RESULTS

Of 4213 patients who underwent mastectomy with immediate TE reconstruction, 91% accepted and 9% declined a nerve block. On univariate analyses, patients with the lowest rate of block refusal were white, non-Hispanic, English speakers, patients with commercial insurance, and patients undergoing bilateral reconstruction. The rate of block refusal went down from 12 in 2017 to 6% in 2022. Multivariable logistic regression demonstrated that older age (p = 0.011), Hispanic ethnicity (versus non-Hispanic; p = 0.049), Medicaid status (versus commercial insurance; p < 0.001), unilateral surgery (versus bilateral; p = 0.045), and reconstruction in earlier study years (versus 2022; 2017, p < 0.001; 2018, p < 0.001; 2019, p = 0.001; 2020, p = 0.006) were associated with block refusal.

CONCLUSIONS

An established preoperative regional anesthesia program with blocks offered to all patients undergoing mastectomy with TE reconstruction can result in decreased racial disparities. However, continued differences in age, ethnicity, and insurance status justify future efforts to enhance preoperative educational efforts that address patient hesitancies in these subpopulations.

Local Infiltration Anesthesia Versus Ultrasound-Guided Pectoralis (PEC1) + Serratus Anterior Plane (SAP) Blocks on Postanesthetic Care Unit Pain Control in Patients Undergoing Primary Submuscular Augmentation Mammoplasty

BACKGROUND

Ultrasound-guided regional field blocks are not widely used in outpatient plastic surgeries. The efficacy of truncal blocks (PEC1 + SAP) has not been established in plastic surgery. The purpose of this study was to analyze the outcomes of these newer anesthetic techniques compared with traditional blind local anesthetic infiltration in patients undergoing breast augmentation.

METHODS

This retrospective institutional review board-approved cohort study compared the outcomes of the different practices of 2 plastic surgeons at the same accredited outpatient surgery center between 2018 and 2022. Group 1 received an intraoperative blind local infiltration anesthetic. Group 2 underwent surgeon-led, intraoperative, ultrasound-guided PEC1 (Pectoralis 1) + SAP (serratus anterior plane) blocks. Patients who underwent any procedure other than primary submuscular augmentation mammoplasty were excluded from the study. The outcomes measured included operative time, opioid utilization in morphine milligram equivalents (MME), pain level at discharge, and time spent in the post anesthetic care unit (PACU).

RESULTS

Sixty patients met the inclusion criteria for each group for a total of 120 patients. The study groups were similar to each other. Patients receiving PEC1 + SAP blocks (group 2) had significantly lower average MME requirements in the PACU (3.04 MME vs 4.52 MME, P = 0.041) and required a shorter average PACU stay (70.13 minutes vs 80.38 minutes, P = 0.008). There were no significant differences in the pain level at discharge, operative time, or implant size between the 2 groups.

CONCLUSIONS

Surgeon-led, intraoperative, ultrasound-guided PEC1 + SAP blocks significantly decreased opioid utilization in the PACU by 33% and patient time in the PACU by 13%, while achieving similar patient pain scores and operating times.

Ultrasound-Guided Transversus Abdominis Plane Blocks Versus Local Infiltration Anesthesia on Postanesthesia Care Unit Pain Control in Patients Undergoing Abdominoplasty

GOALS/PURPOSE

The goal of this study was to compare ultrasound-guided transversus abdominis plane (TAP) blocks to local infiltration anesthesia with or without blind rectus sheath blocks in patients who underwent abdominoplasty at an outpatient surgery center.

METHODS/TECHNIQUE

A retrospective review was conducted of patients who underwent outpatient abdominoplasty performed by the senior surgeon (J.T.L.). Group 1 received local infiltration anesthesia with or without blind rectus sheath blocks between April 2009 and December 2013. Group 2 received surgeon-led, intraoperative, ultrasound-guided, 4-quadrant TAP blocks between January 2014 and December 2021. Outcomes measured were opioid utilization (morphine milligram equivalents), pain level at discharge, and time spent in postanesthesia care unit (PACU).

RESULTS

Sixty patients in each of the 2 study groups met the study criteria for a total of 120 patients. The study groups were similar except for a lower average age in group 1. Patients who received TAP blocks (group 2) had significantly lower morphine milligram equivalent requirements in the PACU (3.07 vs 8.93, P = 0.0001) and required a shorter stay in PACU (95.4 vs 117.18 minutes, P = 0.0001). There were no significant differences in pain level at discharge.

CONCLUSIONS

Surgeon-led, intraoperative, ultrasound-guided, 4-quadrant TAP blocks statistically significantly reduced opioid utilization in PACU by 65.6% and average patient time in the PACU by 18.5% (21.8 minutes).

Variability in Opioid Prescribing Among Plastic Surgery Residents After Bilateral Breast Reduction

BACKGROUND

Prescription opioid misuse in the United States accounts for significant avoidable morbidity and mortality. Over one third of all prescriptions written by surgeons are for opioids. Although opioids continue to provide needed analgesia for surgical patients, there are few guidelines in the plastic surgery literature for their safe and appropriate use after surgery. The consequence is wide variability and excessive opioid prescriptions. Understanding patterns of prescribing among plastic surgery residents is a crucial step toward developing safer practice models for managing postoperative pain.

METHODS

The authors performed a retrospective analysis of discharge opioid prescriptions after bilateral breast reduction at a single academic medical center from 2018 to 2021. Single factor 1-way analysis of variance was used to evaluate prescribing patterns by resident, postgraduate year, attending of record, and patient characteristics for 126 patients. A multivariate analysis was performed to determine the degree to which these factors predicted opioid prescriptions.

RESULTS

This analysis revealed significant variability among residents prescribing opioids after bilateral breast reductions ( P < 0.001) irrespective of patient comorbidities and demographics. Residents were found to be the main predictor of opioid prescriptions after surgery ( P < 0.001) with a greater number of morphine milligram equivalents prescribed by the more junior residents ( P < 0.001).

CONCLUSIONS

Excessive and variable opioid prescriptions among plastic surgery residents highlight the need for opioid prescribing education early in surgical training and improved oversight and communication with attending surgeons. Furthermore, implementation of evidence-based opioid-conscious analgesic protocols after common surgical procedures may improve patient safety by standardizing postoperative analgesic prescriptions.

Safe Reproducible Breast Reduction

Breast reduction is a common operation performed by plastic surgeons. Patients can have significant improvement in physical symptoms in addition to increased self-esteem, body image, and quality of life as a result. The authors describe common techniques for breast reduction and provide representative photographs and videos of these techniques. An evidence-based review is provided for patient selection criteria, common surgical techniques, and methods to avoid and treat complications. Information is also provided on patient education about breast reduction. In most cases, breast reduction is safe to perform in the outpatient setting. The Wise pattern and vertical pattern are among the most common techniques for skin incisions, and the inferior and superomedial pedicles are two of the most common pedicles used in breast reduction. Enhanced Recovery After Surgery protocols are helpful to effectively control pain and reduce narcotic use postoperatively. Patient satisfaction after breast reduction surgery is typically high. Multiple techniques are available to successfully perform breast reduction. The plastic surgeon needs to select patients carefully and determine the appropriate technique to use. Patient education about the operation, recovery, expected result, and risks is an important component of achieving an optimal result.

Trends and Innovations in Autologous Breast Reconstruction

More than 40 years have passed since the description of the first "free abdominoplasty flap" for breast reconstruction by Holmström. In the meantime, surgical advances and technological innovations have resulted in the widespread adoption of autologous breast reconstruction to recreate the female breast after mastectomy. While concepts and techniques are continuing to evolve, maintaining an overview is challenging. This article provides a review of current trends and recent innovations in autologous breast reconstruction.

Paravertebral Blocks in Tissue Expander Breast Reconstruction: Propensity-Matched Analysis of Opioid Consumption and Patient Outcomes

BACKGROUND

The paravertebral block (PVB) is an adjunctive perioperative pain control method for patients undergoing breast reconstruction that may improve perioperative pain control and reduce narcotic use. This study determined the efficacy of preoperative PVBs for perioperative pain management in patients undergoing tissue expander breast reconstruction.

METHODS

A retrospective review was performed of patients who underwent tissue expander breast reconstruction from December of 2017 to September of 2019. Two patients with PVBs were matched using propensity scoring to one no-block patient. Perioperative analgesic use, pain severity scores on days 2 to 10 after discharge, and BREAST-Q Physical Well-Being scores before surgery and at 2 weeks, 6 weeks, and 3 months after surgery were compared between the two groups.

RESULTS

The propensity-matched cohort consisted of 471 patients (314 PVB and 157 no block). The PVB group used significantly fewer morphine milligram equivalents than the no-block group (53.7 versus 69.8; P < 0.001). Average daily postoperative pain severity scores were comparable, with a maximum difference of 0.3 points on a 0-point to 4-point scale. BREAST-Q Physical Well-Being scores were significantly higher for the PVB group than the no-block group at 6 weeks after surgery (60.6 versus 51.0; P = 0.015) but did not differ significantly at 2 weeks or 3 months after surgery.

CONCLUSIONS

PVBs may help reduce perioperative opioid requirements but did not reduce pain scores after discharge when used as part of an expander-based reconstruction perioperative pain management protocol. Continued research should examine additional or alternative regional block procedures as well as financial cost and potential long-term impact of PVBs.

Office-based Plastic Surgery-Evidence-based Clinical and Administrative Guidelines

Outpatient procedures are extremely prevalent in plastic surgery, with an estimated 82% of cosmetic plastic surgery occurring in this setting. Given that patient safety is paramount, this practical review summarizes major contemporary, evidence-based recommendations regarding office-based plastic surgery. These recommendations not only outline clinical aspects of patient safety guidelines, but administrative, as well, which in combination will provide the reader/practice with a structure and culture that is conducive to the commitment to patient safety. Proper protocols to address potential issues and emergencies that can arise in office-based surgery, and staff familiarity with thereof, are also necessary to be best prepared for such situations.

PEC block versus local anesthetic infiltration in breast implant augmentation surgery: a retrospective study

INTRODUCTION

Pectoral plane (PEC) blocks are routinely used in analgesia for patients undergoing dual-plane breast augmentation with implants. Local anesthetic infiltration (LAI) is a simple alternative technique with the same aim. We evaluated both techniques.

MM

In this single-center retrospective study, patients received PEC block (ropivacaine 0.2%, 10 ml PEC I, 20 ml PEC II) or LAI. The primary outcome measure was pain, according to the visual analog scale (VAS), at 24h post-surgery. Secondary outcomes included the measure of pain at 1, 2, 6, and 12 hours post-surgery, total opioid consumption at 24h, and opioid side effects.

RESULTS

81 were finally recruited: 37 in the PEC group and 44 in the LAI group. Patient characteristics were comparable between the two groups. At 24h post-surgery, the LAI group showed a decrease in pain, with a VAS score of 0.7 vs 1.5 in the PEC group (p = 0.007). There was no difference in VAS between the two groups at 1, 2, 6, or 12 hours post-surgery. The duration of anesthesia was increased in the PEC group with 153 minutes vs 120 minutes in the LAI group (p < 0.001). There was no difference in rescue morphine consumption between the two groups.

CONCLUSIONS

We found that LAI had a superior analgesic effect at 24h after surgery for dual-plane breast implant augmentation compared with PEC block. These findings are a good indication that the LAI technique is at least as effective as PEC block while being safe, fast, and easy to use.

Multimodal Analgesia in the Aesthetic Plastic Surgery: Concepts and Strategies

Postoperative pain management is crucial for aesthetic plastic surgery procedures. Poorly controlled postoperative pain results in negative physiologic effects and can affect length of stay and patient satisfaction. In light of the growing opioid epidemic, plastic surgeons must be keenly familiar with opioid-sparing multimodal analgesia regimens to optimize postoperative pain control.

Methods

A review study based on multimodal analgesia was conducted.

Results

We present an overview of pain management strategies pertaining to aesthetic plastic surgery and offer a multimodal analgesia model for outpatient aesthetic surgery practices.

Conclusion

This review article presents an evidence-based approach to multimodal pain management for aesthetic plastic surgery.

Applications of Ultrasound in the Postoperative Period: A Review

Background Recent advances in ultrasound technology have further increased its potential for routine use by plastic and reconstructive surgeons.

Methods An extensive literature review was performed to determine the most common applications of ultrasound in the postoperative care of plastic and reconstructive surgery patients.

Results In contrast with other available imaging modalities, ultrasound is cost-effective, rapid to obtain, eliminates the need for ionizing radiation or intravenous contrast, and has virtually no contraindications. In addition to its diagnostic capabilities, ultrasound can also be used to facilitate treatment of common postoperative concerns conveniently at the bedside or in an office setting.

Conclusion This article presents a review of the current applications of ultrasound imaging in the postoperative care of plastic and reconstructive surgery patients, including free flap monitoring following microsurgery, diagnosis and treatment of hematoma and seroma, including those associated with BIA-ALCL, and breast implant surveillance.

Emerging drugs for the treatment of postsurgical pain

INTRODUCTION

Postoperative pain is a distressful experience and remains to be a significant concern after surgery. Current agents either fail to prevent or minimize postoperative pain or cause a series of adverse effects, addiction, or abuse. Opioids have been the gold standard in the treatment of postoperative pain despite their well-described adverse effects. Many new agents with different mechanisms of action have been recently introduced to address this issue.

AREAS COVERED

This current review summarizes the list of new and emerging drugs investigated for their efficacy in controlling the postoperative pain and decreasing the need for rescue opioid use, adverse effect profile, abuse, and addiction potential.

EXPERT OPINION

Opioids have unrivaled analgesic efficacy. However adverse effects of opioids led to the search for better options. In mild pain most of the emerging drugs have been shown to control postoperative pain and decrease the use of rescue opioid, however fail to control pain after major surgeries causing severe pain. Specific agents such as Oliceridine, new local anesthetics, etc., are effective in controlling severe pain and hold a promise to replace opioids in the near future.
