The Use of Liposomal Bupivacaine in Erector Spinae Plane Block to Minimize Opioid Consumption for Breast Surgery: A Case Report

The Utility of Erector Spinae Plane Blocks in Breast Surgery: A Practical Review

Background

In plastic surgery, breast surgery patients are among the most susceptible to postoperative pain. Amidst the opioid epidemic, healthcare goals seek to optimize nonopioid multimodal pain control by including regional analgesia. The erector spinae plane block (ESPB) is among several regional blocks used in breast surgery. Although the paravertebral block has previously served as the gold standard, new research focused on ESPB may shift standards.

Methods

A comprehensive PubMed review was performed in September 2023 to identify articles related to ESPB use in breast surgery. Non-English and unavailable articles were excluded. Data extracted included publication year, techniques, and outcomes.

Results

Sixty-eight publications were included, of which 31 were randomized control trials (45.6%). Most were published between 2021 and 2023 (n = 40, 58.8%). Most articles that evaluated pain and opioid use suggested that ESPB performed better than nonblocked groups (n = 26, 38.2% of total articles and n = 4, 5.88% of total articles) and performed similarly to other blocks. However, articles that evaluated the pectoral nerve block suggested it outperformed ESPB in these aspects (n = 6 articles, 8.82%). ESPB was shown to be a safe and procedurally short block to perform, effective in the hands of novice providers.

Conclusions

ESPB offers reliable outcomes, improving pain control and decreasing opioid consumption. In turn, this can decrease healthcare costs and patient morbidity.

Erector Spinae Plane Block for the Treatment of Intractable Pain in a Patient with Pancoast Tumor: A Case Report

Introduction

The erector spinae plane (ESP) block is a regional anesthetic technique that involves injecting a local anesthetic below the erector spinae muscle in an interfascial plane.

Case Presentation

We report a case of a 66-year-old man with cervicothoracic junction pain caused by an advanced Pancoast tumor. The administration of ESP block at the T2-T3 level led to pain relief of more than 50% in this patient after two sessions.

Conclusions

Therefore, the application of this method of regional analgesia is both convenient and safe and reduces opioid consumption. Further studies are needed to evaluate the safety and effectiveness of continuous blocks in outpatient settings.

A Novel Use of Liposomal Bupivacaine in Erector Spinae Plane Block for Pediatric Congenital Cardiac Surgery

We describe the use of liposomal bupivacaine (Exparel) in erector spinae plane blocks for two patients undergoing pediatric cardiac surgery with cardiopulmonary bypass and one undergoing division of the compressive vascular ring. The perioperative course of all patients was remarkable for low pain and sedation scores, especially after chest tube removal. Erector spinae plane blocks are an expanding pain-control technique in both adult and pediatric cardiac surgery for postoperative analgesia. Liposomal bupivacaine offers prolonged analgesia and may be an attractive option for this indication.

Regional Anesthesia in Neuroanesthesia Practice

Regional anesthesia has been an undervalued entity in neuroanesthetic practice. However, in the past few years, owing to the development of more advanced techniques, drugs and the prolific use of ultrasound guidance, the unrecognised potential of these modalities have been highlighted. These techniques confer the advantages of reduced requirements for local anesthetics, improved hemodynamic stability in the intraoperative period, better pain score postoperatively and reduced analgesic requirements in the postoperative period. Reduced analgesic requirement translates into lesser side effects associated with analgesic use. Furthermore, the transition from the traditional blind landmark-based techniques to the ultrasound guidance has increased the reliability and the safety profile. In this review, we highlight the commonly practised blocks in the neuroanesthesiologist's armamentarium and describe their characteristics, along with their individual particularities.

Erector Spinae Plane Block Decreases Pain and Opioid Consumption in Breast Surgery: Systematic Review

Adequate control of acute postoperative pain is crucial in breast surgeries, as it is a significant factor in the development of persistent chronic pain. Inadequate postoperative pain control increases length of hospital stays and risk of severe complications. Erector spinae plane block (ESPB) is a novel regional block that has the ability to sufficiently block unilateral multidermatomal sensation from T1 to L3. By reviewing the literature on ESPB, this paper aimed to elucidate its efficacy in breast surgery analgesia and its role in addressing the opioid crisis in North America.

Multimodal analgesia with multiple intermittent doses of erector spinae plane block through a catheter after total mastectomy: a retrospective observational study

BACKGROUND

Although case reports have suggested that the erector spinae plane block (ESPB) may help analgesia for patients after breast surgery, no study to date has assessed its effectiveness. This retrospective observational study analyzed the analgesic effects of the ESPB after total mastectomy.

METHODS

Forty-eight patients were divided into an ESPB group (n = 20) and a control group (n = 28). Twenty patients in the control group were selected by their propensity score matching the twenty patients in the ESPB group. Patients in the ESPB group were injected with 30 mL 0.375% ropivacaine, followed by catheter insertion for further injections of local anesthetics every 12 hours. Primarily, total fentanyl consumption was compared between the two groups during the first 24 hours postoperatively. Secondary outcomes included pain intensity levels (visual analogue scale) and incidence of postoperative nausea and vomiting (PONV).

RESULTS

Median cumulative fentanyl consumption during the first 24 hours was significantly lower in the ESPB (33.0µg; interquartile range [IQR], 27.0-69.5µg) than in the control group (92.8µg; IQR, 40.0-155.0µg) (P = 0.004). Pain level in the early postoperative stage (<3 hr) and incidence of PONV (0% vs. 55%) were also significantly lower in the ESPB group compared to the control (P = 0.001).

CONCLUSIONS

Intermittent ESPB after total mastectomy reduces fentanyl consumption and early postoperative pain. ESPB is a good option for multimodal analgesia after breast surgery.

Ultrasound-Guided Bilateral Erector Spinae Block Versus Tumescent Anesthesia for Postoperative Analgesia in Patients Undergoing Reduction Mammoplasty: A Randomized Controlled Study

PURPOSE

The aim of this prospective, randomized, double-blind study was to compare the tumescent anesthesia method and erector spinae block with respect to postoperative analgesia consumption, pain scores and patient satisfaction, in patients receiving breast reduction surgery under general anesthesia.

METHODS

The study included 44 females, aged 20-65 years, who were to undergo breast reduction surgery, without adjunctive liposuction on the breast. Using the closed envelope method, the patients were randomly separated into two groups to receive tumescent anesthesia or erector spinae block (ESB). Patients in the ESB group received the block before general anesthesia by a single anesthetist (G.Ö.).

RESULTS

The 24-h tramadol consumption with PCA, which was the primary outcome of the study, was determined to be statistically significantly less in the ESB group (p < 0.001). The NRS scores were compared at 30 min postoperatively and then at 1, 2, 4, 6, 12 and 24 h. At all the measured time points, the pain scores of the ESB group were statistically significantly lower (p < 0.001). Additional analgesia was required by one patient in the ESB group and by seven patients in the tumescent group and was applied as 1 g paracetamol. The requirement for additional analgesia was statistically significantly lower in the ESB group (p < 0.024). Patient satisfaction was statistically significantly better in the ESB group (p < 0.001).

CONCLUSIONS

According to the results of this study, bilateral ESB performed under ultrasound guidance in breast reduction surgery was more effective than tumescent anesthesia concerning postoperative analgesia consumption and pain scores. ESB could be an appropriate, effective and safe postoperative analgesia method for patients undergoing reduction mammoplasty surgery.

The erector spinae plane block: a narrative review

Regional anesthesia and pain management have experienced advances in recent years, especially with the advent of fascial plane blocks. The erector spinae plane block is one of the newest techniques to be described. In the past two years, publications referring to ESP block have increased significantly. The objective of this review is to analyze the articles about ESP block that have been published to date. We performed a search in the main databases and identified 368 articles. After a selection of the relevant articles, 125 studies were found eligible and were included in the review. The ESP block is performed by depositing the local anesthetic in the fascial plane, deeper than the erector spinae muscle at the tip of the transverse process of the vertebra. Many cases of its use have been described with satisfactory results in the treatment of both acute pain and chronic pain. The applicability of the technique covers many clinical scenarios. Of the 98 case reports reviewed, 12 and 87 articles, respectively described the technique as a treatment for chronic pain and acute pain. The single-shot was the most frequently used technique. As described in the articles published to date, the technique is easy to perform and has a low rate of complications. However, despite the effectiveness of the technique, further studies are necessary to obtain more evidence of its actions.

Enhanced Recovery Programs in Outpatient Surgery

Although enhanced recovery pathways were initially implemented in inpatients, their principles are relevant in the ambulatory setting. Opioid minimization and addressing pain and nausea through multimodal analgesia, regional anesthesia, and robust preoperative education programs are integral to the success of ambulatory enhanced recovery programs. Rather than measurements of length of stay as in traditional inpatient programs, the focus of enhanced recovery programs in ambulatory surgery should be on improved quality of recovery, pain management, and early ambulation.

Postoperative Analgesic Efficacy of the Ultrasound-Guided Erector Spinae Plane Block in Patients Undergoing Lumbar Spinal Decompression Surgery: A Randomized Controlled Study

BACKGROUND

Spinal surgery is a procedure that causes intense and severe pain in the postoperative period. Erector spinae plane (ESP) block can target the dorsal-ventral rami of thoracolumbar nerves, but its effect on lumbar surgery is unclear. The aim of this study was to investigate the effect of the ESP block on postoperative opioid consumption and pain scores in patients undergoing spinal surgery.

METHODS

Sixty patients undergoing open lumbar decompression surgery were randomly assigned to 2 groups. The ESP Group (n = 30) received ultrasound-guided bilateral ESP block with 0.25% bupivacaine 20 mL. In the Control Group (n = 30), no intervention was performed. Postoperative analgesia was performed intravenously twice a day with 400 mg ibuprofen and patient-controlled analgesia with tramadol. Postoperative visual analogue scale scores, opioid consumption, rescue analgesia, and opioid-related side effects were evaluated.

RESULTS

Compared with the Control Group, the visual analogue scale scores were statistically lower in the ESP Group during all measurements of time, both at rest and active movement (P < 0.05). Tramadol consumption was lower in the ESP Group compared with the Control Group at all time periods (P < 0.05). Twenty-four hour tramadol consumption in the Control Group was significantly higher compared with the ESP Group (370.33 ± 73.27 mg and 268.33 ± 71.44 mg; P < 0.001, respectively) and the difference was 28%, and time to first analgesic requirement was significantly longer in the ESP Group than in the Control Group.

CONCLUSIONS

ESP block can be used in multimodal analgesia practice to reduce opioid consumption and relieve acute postoperative pain in patients undergoing open lumbar decompression surgery.

Erector spinae plane block for postoperative analgesia in laparoscopic cholecystectomy: a case report

The Erector Spinae Plane Block (ESP) is a novel regional technique for anesthesia or analgesia. Originally the ESP block was described in 2016 in a case report regarding analgesia intervention for a case of thoracic neuropathic pain. Since then, there has been growing interest and research adding experience about the ESP block as regional anesthetic and analgesic technique. Reviewing the literature about this novel technique in databases like PubMed using the key words "erector spinae plane block" returns approximately 56 publications. So far there is no available big series of cases or reviews regarding the ESP block. The literature is limited to case reports or case series. With the present case we are interested in exploring the efficacy of ESP block as a postoperative analgesic method for laparoscopic cholecystectomy. We describe the case of a 76-year-old female patient scheduled for laparoscopic cholecystectomy. Written informed consent was granted (for procedure and publication of photos). We applied a bilateral ultrasound-guided ESP block at T6 level while the patient was awake before general anesthesia induction. The anesthetic solution we used consisted of 12 mL Ropivacaine 0.375% plus 2 mg dexamethasone (on each side). After the successful administration of the block (observation of the solution spread between transverse process and the erector spinae muscles), general anesthesia was induced and the procedure was started. Procedure and recovery was uneventful with the patient experiencing very good analgesia (NRS pain score 0 up to 6 hours after block placement). The patient presented mild pain (NRS score of 2-3) after 6 hours and requested the "on demand" pain medication (1 g paracetamol IV) only 10 hours after the ESP block (NRS pain score of 4-5). The patient experienced no nausea or vomiting, was mobilized easily about 6 hours after the block and was discharged the next day. This relatively simple and safe block dramatically reduced the amount of IV pain medication we usually administer for the specific procedure. The overall result was increased satisfaction of the patient and avoidance of opioid use.
