What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests new methods to improve pain management and recovery for patients undergoing breast surgery. The goal is to reduce pain, potentially leading to quicker hospital discharge and better overall patient care.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you use opioids daily over 30 mg of oxycodone or equivalent, you may not be eligible to participate.

Is the nerve block treatment for breast surgery pain generally safe for humans?

The nerve block treatments, such as the Pecto-intercostal Fascial Block (PIFB) and Serratus Plane Block (SPB), have been used in various surgeries and are generally considered safe when performed under ultrasound guidance, which helps ensure accurate placement and reduces risks. ^{1 2 3 4 5}

How does the nerve block treatment for breast surgery pain differ from other treatments?

This treatment is unique because it uses nerve blocks like the Parasternal Block (PSB) and Thoracic Transversus Plane Block (TTP) to specifically target and relieve pain in the internal mammary region, which other common nerve blocks like the Pectoral Nerve Block (PECS) and Serratus Plane Block (SPB) do not effectively address. ^{1 5 6 7 8}

What data supports the effectiveness of this treatment for breast surgery pain?

Research shows that combining different nerve blocks, like the serratus plane block and parasternal block, can effectively reduce pain after breast surgery. These blocks target specific nerves to provide better pain relief in areas that are often difficult to manage with other methods. ^{1 4 5 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• Bilateral parasternal infrapectoral block
• Bilateral serratus plane block

Trial Overview The study is testing two types of nerve blocks—serratus plane block and parasternal infrapectoral block—against placebo, all in combination with general anesthesia for breast reduction surgery. The goal is to see if these blocks improve recovery and reduce hospital stay.

How Is the Trial Designed?

Group I: Study Group Active Control 2 Interventions

Ultrasound guided unilateral serratus plane block and unilateral parasternal infrapectoral block with 0.5% ropivacaine.

Group II: Control Group Placebo Group 2 Interventions

Ultrasound guided unilateral serratus plane block and unilateral parasternal infrapectoral block with 0.9% saline.

Published Research Related to This Trial

A case study of a 60-year-old man with persistent post-thoracotomy pain showed that using Parasternal Block (PSB) and Thoracic Transversus Plane Block (TTP) effectively eliminated pain in the internal mammary region after previous treatments with Pectoral Nerves Block (PECS) and Serratus Plane Block (SPB).

The pain relief achieved with PSB and TTP, combined with hydrodissection using triamcinolone and Ropivacaine, was sustained for at least 3 months, suggesting this approach could be a valuable option for managing residual pain in similar patients.

The addition of the pectointercostal fascial plane block (PIFB) to the ultrasound-guided serratus anterior plane block (SAPB) significantly reduced the need for intraoperative fentanyl and resulted in lower mean arterial blood pressure and heart rate during surgery, indicating improved hemodynamic stability.

Despite these benefits, both groups showed similar postoperative pain scores and opioid consumption, suggesting that while PIFB may enhance intraoperative analgesia, it does not significantly impact overall postoperative pain management compared to SAPB alone.

The serratus-intercostal plane block (SIPB) provides effective perioperative analgesia for patients undergoing partial mastectomy, with sensory loss extending over multiple intercostal spaces for 12 to 24 hours after administration.

In a study involving more than 20 patients, SIPB did not result in sensory loss at the T1 dermatomal distribution, indicating that additional analgesic methods may be necessary when performing axillary dissection.

In a study of 61 women undergoing modified radical mastectomy, the combination of pectoral nerve block I (PECS I) and serratus-intercostal plane block (SPB) significantly reduced pain scores and opioid consumption compared to general anesthesia alone.

Patients receiving the PECS I + SPB treatment reported better sleep quality and higher satisfaction with pain relief, indicating that this multimodal analgesic strategy enhances postoperative recovery.

In a study of 40 female patients undergoing radical mastectomy, the ultrasound-guided serratus anterior plane block (SAPB) provided significantly longer-lasting pain relief compared to the thoracic paravertebral block (TPVB), with patients in the SAPB group waiting an average of 255.3 minutes for their first rescue analgesia versus 146.8 minutes for the TPVB group.

Patients receiving SAPB also consumed less total analgesics (diclofenac) in the first 24 hours and reported lower postoperative pain scores, along with a reduced incidence of postoperative nausea and vomiting (PONV), indicating that SAPB is a safer and more effective option for managing post-surgical pain.

In a study of 108 patients undergoing open cardiac surgery, those who received bilateral Pecto-intercostal Fascial Block (PIFB) experienced significantly less postoperative pain and required less pain medication compared to those who did not receive the block.

The PIFB group also had faster recovery times, including shorter ICU stays and overall hospital stays, along with lower levels of insulin and inflammatory markers three days post-surgery, indicating improved recovery outcomes.

In a study involving 39 cardiac surgery patients, both the bilateral pectointercostal fascial block (PIFB) and transversus thoracic muscle plane block (TTMPB) were found to be equally effective in reducing morphine consumption and pain scores within the first 24 hours post-surgery.

However, patients receiving the PIFB experienced a longer time before their first request for analgesia compared to those receiving TTMPB, suggesting that while both techniques are effective, PIFB may provide a delayed onset of pain relief.

The pectoral nerve (PECS) block significantly reduced postoperative pain levels and the need for propofol during breast cancer surgery, indicating its efficacy in pain management.

However, the PECS block did not improve the overall quality of recovery (QoR) scores on the first postoperative day, suggesting that while it helps with immediate pain relief, other factors may influence recovery that are not captured by pain scores alone.

In a study involving 64 women undergoing unilateral modified radical mastectomy, the pectoralis-serratus interfascial plane block resulted in higher postoperative morphine consumption and a shorter time to first analgesic request compared to the thoracic paravertebral block, indicating it may not be as effective for pain management.

While both techniques provided low pain intensity in the early postoperative hours, the thoracic paravertebral block showed significantly better pain control at 8, 16, and 24 hours post-surgery, suggesting it is the superior option for managing postmastectomy pain.
