Regional Anesthesia for Breast Surgery: Techniques and Benefits

Erector Spinae Plane (ESP) Block for Postoperative Pain Management after Open Oncologic Abdominal Surgery

Patients undergoing abdominal oncologic surgical procedures require particular surgical and anesthesiologic considerations. Traditional pain management, such as opiate treatment, continuous epidural analgesia, and non-opioid drugs, may have serious side effects in this patient population. We evaluated erector spinae plane (ESP) blocks for postoperative pain management following elective oncologic abdominal surgeries. In this single-center, prospective, and randomized study, we recruited 100 patients who underwent elective oncological abdominal surgery between December 2020 and January 2022 at Soroka University Medical Center in Beer Sheva, Israel. We compared postoperative pain levels in patients who were treated with a preincisional ESP block in addition to traditional pain management with intravenous opioids, non-steroidal anti-inflammatory drugs (NSAIDs), and acetaminophen, compared to patients who were only given traditional pain management (control). Patients who were treated with a preincisional ESP block demonstrated significantly lower Visual Analog Scale scores at 60 minutes and 4, 8, and 12 hours following the surgery, compared to the control group (p < 0.001). Accordingly, patients in the ESP group required less morphine from 60 minutes to 12 hours after surgery, but they required increased non-opioid postoperative analgesia management at 4, 8, and 12 hours after surgery (p from 0.002 to <0.001) compared to the control group. In this study, we found ESP blocks to be a safe, technically simple, and effective treatment for postoperative pain management after elective oncologic abdominal procedures.

Analgesic efficacy of the superficial versus deep serratus plane blocks for mastectomy with axillary clearance: A randomized controlled trial

BACKGROUND

The serratus plane block is an effective technique for providing analgesia to patients undergoing breast surgery.

METHODS

This prospective, double-blind, randomized study enrolled 60 female patients scheduled for unilateral mastectomy and axillary clearance. The patients received either a superficial serratus plane block or deep serratus plane block. Dermatomal spread was recorded 30 minutes after block administration. Postoperatively, pain visual analog scale (VAS) scores were documented at recovery (time 0), at 30 minutes; and in the ward hourly for 4 hours, and 4-hourly until 24 hours postoperatively. The time to first analgesic rescue and cumulative morphine consumption using patient-controlled analgesia morphine (PCAM) were recorded.

RESULTS

The results showed lower VAS scores at rest (at 1, 2, 3, and 4 hours postoperatively), and during movement (at 1, 2, 3, 4, 8, and 24 hours postoperatively) in the superficial serratus plane block group, P < .005. Similarly, cumulative morphine usage was lower in the superficial serratus plane group, P < .005. The time to the first rescue analgesic was also significantly longer in the superficial group, P < .001. More patients in the superficial serratus plane group achieved greater dermatomal spread at T2 and T7 than those in the deep group.

CONCLUSIONS

Superficial serratus plane block provides better analgesic efficacy than deep serratus plane block in mastectomy and axillary clearance.

Serratus Anterior Plane Block for Awake Breast Surgery: A Case Report

Thoracic fascial blocks have been included in multimodal analgesia for breast surgery. Fewer studies demonstrate its use as a regional anesthesia technique. The serratus anterior plane (SAP) block provides anesthesia to the lateral thoracic wall and the axilla, the surgical area of some breast surgeries, with a single injection.This article reports the use of the SAP block as an anesthetic technique for breast lumpectomy with axillary dissection ensuring good surgical conditions and patient safety.

Establishing a Technique for Pectoral II-Block Catheter Insertion with Ultrasound Guidance: A Randomized Controlled Trial

Purpose

To assess the efficacy and safety of a modified technique for ultrasound-guided pectoral II block for postoperative pain control after mastectomy.

Methods

In this randomized controlled trial, patients were randomly allocated into two groups (40 patients each). Group I patients were subjected to ultrasound-guided pectoral II block with injection of 10 mL lidocaine 1% as a dissecting solution before attempting catheter insertion, while group II patients underwent the standard procedure without a dissecting solution. Measured outcomes included catheter visibility, pain, patient satisfaction, performance time, and complications.

Results

Compared with group II, group I had significantly lower median catheter-visibility scores, shorter block performance time, and fewer insertion attempts. Group I had a nonsignificantly higher rate of complications than group II.

Conclusion

The modified technique facilitated the procedure, shortened the catheter-insertion time, and showed higher patient satisfaction. However, it was associated with lower catheter visibility on ultrasonography. Further studies are required to confirm the present findings and assess the safety of the modified technique.

Radioactive Seed Localization Program for Patients With Nonpalpable Breast Lesions

Without early diagnosis and treatment, many lives are lost to breast cancer. Increased breast cancer awareness has facilitated research to guide health care providers toward improving patient outcomes. Research in diagnostic and treatment modalities has expanded to focus on improving the quality of life for patients with breast cancer who are living longer than expected. Providers can offer patients with nonpalpable breast lesions new screening techniques and improved treatment options, including radioactive seed localization lumpectomy. This treatment offers patients the potential for decreased tumor re-excision for positive margins near the surgical site, a lower volume of excised breast tissue, decreased operative time, convenient surgical scheduling, and less pain. Additionally, radioactive seed localization lumpectomy can improve patient and staff member satisfaction.
