The Use of Pecs Blocks in Combination With Exparel in Breast Reconstruction Surgery
Study Details
Study Description
Brief Summary
This project intends to more thoroughly investigate the direct influence of Pecs blocks in the administration of Exparel, a non-opioid analgesic, in breast reconstruction surgery. The hypothesis is that this analgesic delivery method will significantly reduce negative outcomes such as post-operative pain, opioid use, and nausea while increasing positive outcomes such as post-operative physical activity.

Detailed Description
The research team will be investigating the use of a novel type of local drug administration as well as assessing whether a non-opioid based drug will result in more positive pain outcomes while reducing reliance on narcotics (opioid-based drugs) following surgery.
The drug administration tool, called the Pecs blocks types I and II, utilizes ultrasound to help guide anesthetic injection for local anesthesia. This has been an effective way to deliver local anesthetic during breast surgeries. Meanwhile, a non-opioid analgesic drug (similar to an anesthetic, meaning it is used during surgery to reduce pain) called Exparel has been shown to reduce post-operative use of narcotics, length of stay in hospitals, and pain compared to the current standards in breast reconstruction surgery. Exparel is approved by the FDA for use in surgical sites during breast reconstruction surgery. Exparel has shown to reduce pain and post-surgical nausea and vomiting in breast reconstruction patients. However, the combination of Exparel with Pecs blocks has not been examined in breast reconstruction surgery, and the research team suspects that breast reconstruction patients who are administered Exparel with Pecs blocks will experience less pain, increased mobility, and less nausea following surgery. Furthermore, the researchers hope to show that this non-opioid based drug successfully reduces the necessity to use narcotics following surgery. Narcotics are highly addictive and can lead to dependency following surgery.
The reason the project has three different groups in this study is to show if each group has different outcomes. First, the project hopes to see a difference between the Pecs blocks and normal anesthesia delivery. Then, researchers hope to see a difference between the two Pecs blocks group where the use of Exparel will result in less narcotic use, pain, nausea, and increase mobility.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Other: Intravenous lidocaine Intravenous (IV) lidocaine infusion without Pecs block (standard of care per ERAS protocol) |
Procedure: Breast Reconstruction (Mammaplasty)
Breast Reconstruction (mammaplasty) surgery with implant-based tissue expander
Drug: Lidocaine
This is an anesthetic delivered during breast reconstruction surgery that will be given to participants in arm 1.
|
Active Comparator: Blocks+Bupivacaine Use of Pecs block types I and II with bupivacaine as local anesthetic |
Procedure: Breast Reconstruction (Mammaplasty)
Breast Reconstruction (mammaplasty) surgery with implant-based tissue expander
Device: Pecs blocks
Pectoral nerve (Pecs) blocks I and II function by blocking the pectoral, intercostal, intercostobrachial nerves, and/or long thoracic nerve. These are used primarily for breast surgeries and are gaining momentum as simple administers of local analgesics. Pecs blocks utilize ultrasound to guide injection of local analgesic. It is less invasive and more accurate than most current modes of analgesia administration.
Other Names:
Drug: Bupivacaine
This is an anesthetic delivered during breast reconstruction surgery that will be given to participants in arms 2 and 3.

Experimental: Blocks+Bupivacaine+Exparel Use of Pecs block types I and II with mixture of bupivacaine and Exparel* (*Must include bupivacaine at lower dose to decrease intra-operative variability in pain control due to delayed onset of Exparel and in ability to use lidocaine infusion with injection of Exparel) |
Procedure: Breast Reconstruction (Mammaplasty)
Breast Reconstruction (mammaplasty) surgery with implant-based tissue expander
Device: Pecs blocks
Pectoral nerve (Pecs) blocks I and II function by blocking the pectoral, intercostal, intercostobrachial nerves, and/or long thoracic nerve.

It is less invasive and more accurate than most current modes of analgesia administration.
Other Names:
Drug: Exparel
Exparel is a sterile, non-pyrogenic white to off-white preservative-free aqueous suspension of multivesicular liposomes (DepoFoam® drug delivery system) containing bupivacaine. Bupivacaine is present at a concentration of 13.3 mg/mL. After injection of Exparel, bupivacaine is released from the multivesicular liposomes over a period of time.
Drug: Bupivacaine
This is an anesthetic delivered during breast reconstruction surgery that will be given to participants in arms 2 and 3.

Outcome Measures
Primary Outcome Measures
- Opioid consumption [2 weeks post op]
• Investigate amount of post-operative opioid consumption post operatively
Secondary Outcome Measures
- Nausea [2 weeks post op]
• Assess Post-Operative Nausea scores among the three arms using the participant-recorded Edmonton Symptom Assessment tool which scores on a scale of one to ten, where ten is the most nausea experienced
- Mobility [2 weeks post op]
• Assess post-operative mobility using the participant-recorded Edmonton Symptom Assessment tool which scores on a scale of one to ten where ten is the most immobile
- Pain Outcomes [2 weeks post op]
• Assess the pain patients experience throughout their recovery period using the participant-recorded Edmonton Symptom Assessment tool which scores on a scale of one to ten where ten is the highest pain
