What is the purpose of this trial?

This trial explores whether the drug Exparel (bupivacaine liposome injectable suspension) can manage pain more effectively after rib cartilage removal during nose surgery compared to the usual treatment with Xylocaine. Both drugs numb the area, but Exparel is designed to last longer. Individuals needing nose surgery for breathing issues or cosmetic reasons, who also require rib cartilage removal, might be suitable candidates. However, those with ongoing heart or lung conditions or who take blood thinners may not qualify for this trial. As a Phase 4 trial, Exparel is already FDA-approved and proven effective, and this research aims to understand its benefits for more patients.

Will I have to stop taking my current medications?

The trial requires that you stop taking anticoagulation medications like aspirin, Coumadin, or Plavix during the study. If you are on these medications, you would need to discontinue them to participate.

What is the safety track record for these treatments?

Research has shown that Exparel, a long-lasting numbing medication, is generally safe for people. One study reported no immediate or delayed adverse reactions linked to Exparel. Another study found a low overall rate of side effects, with serious side effects occurring in about 8% of cases. Common mild side effects included nausea and loss of feeling.

The FDA has approved Exparel for certain uses, indicating its safety for those conditions. Overall, Exparel appears to be a well-tolerated treatment option. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Researchers are excited about Exparel® for pain control in rhinoplasty because it offers prolonged pain relief with a single injection. Unlike standard options like Xylocaine®, which typically provide short-term relief, Exparel® uses a unique liposomal delivery system to release the anesthetic slowly over several days. This means patients could experience less pain and need fewer additional pain medications post-surgery, making recovery smoother and more comfortable.

What evidence suggests that this trial's treatments could be effective for pain control after rib cartilage removal?

Research shows that Exparel, a long-lasting numbing medicine, reduces pain after surgery. In this trial, participants will receive either Exparel or Xylocaine as part of their treatment. Studies have found that Exparel lowers both pain levels and the need for opioids (strong painkillers) after nose surgery. It provides pain relief for up to 72 hours, aiding recovery. Patients who receive Exparel report less pain and reduced opioid use, helping to avoid side effects. Overall, Exparel is a proven choice for effectively managing post-surgical pain. ^{1 5 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Exparel
• Xylocaine

Trial Overview The study aims to compare pain control after rib cartilage removal using EXPAREL®, a long-acting numbing medication lasting about 96 hours, against the standard XYLOCAINE® injection.

How Is the Trial Designed?

Group I: Exparel® Injection Group Experimental Treatment 1 Intervention

On the day of clinically indicated nasal surgery the surgical wound on the chest, where the rib cartilage is removed, will be injected with Exparel®

Group II: Xylocaine® Injection Group Active Control 1 Intervention

On the day of clinically indicated nasal surgery the surgical wound on the chest, where the rib cartilage is removed, will be injected with Xylocaine® as part of standard of care.

Exparel is already approved in United States for the following indications:

Approved in United States as Exparel for:

• Postsurgical local analgesia via infiltration in patients aged 6 years and older
• Postsurgical regional analgesia via an interscalene brachial plexus block in adults
• Postsurgical regional analgesia via a sciatic nerve block in the popliteal fossa in adults
• Postsurgical regional analgesia via an adductor canal block in adults

Published Research Related to This Trial

EXPAREL® (bupivacaine liposome injectable suspension) is an FDA-approved extended-release anesthetic that significantly reduces postoperative pain and opioid consumption in patients undergoing total knee and hip replacement surgeries, as shown in multiple phase 2 and phase 3 studies.

Using EXPAREL® as part of a multimodal pain management approach leads to better outcomes, including lower pain scores, reduced need for rescue opioids, and improved patient satisfaction during recovery.

Recent advances in incorporation of local analgesics in postsurgical pain pathways. Lombardi, AV.[2014]

In a study involving 98 mice, liposomal bupivacaine (Exparel®) provided a longer duration of pain relief compared to standard bupivacaine, with motor block lasting up to 180 minutes and thermoalgesic block lasting up to 420 minutes.

The addition of dexamethasone, either perineurally or systemically, significantly reduced neural inflammation caused by bupivacaine, and perineural dexamethasone also helped reduce inflammation from Exparel®, suggesting a protective effect against nerve damage.

In a study involving 100 patients with pulpal necrosis, liposomal bupivacaine did not show a statistically significant improvement in postoperative pain relief compared to standard bupivacaine, with success rates of 29% and 22% respectively.

While liposomal bupivacaine had some effects on soft tissue numbness and non-narcotic medication use, these effects were not clinically significant, indicating that it may not provide additional benefits over traditional bupivacaine for postoperative pain management.

Liposomal bupivacaine (Exparel) has been shown to be a safe and effective option for managing postoperative pain in plastic surgery, based on a review of eight studies involving 405 patients.

Compared to traditional pain management methods, liposomal bupivacaine was found to be equivalent or more effective, suggesting it could serve as a less invasive alternative to more complex pain management systems.

EXPAREL® (bupivacaine liposome injectable suspension) is an effective extended-release local anesthetic that can significantly improve postoperative pain management in orthopedic trauma surgery, as demonstrated in two case studies.

Both patients treated with EXPAREL® experienced good control of postsurgical pain, highlighting its safety and efficacy as part of a multimodal analgesia approach in reducing the risk of chronic pain after surgery.

EXPAREL® (bupivacaine liposome injectable suspension) provides effective pain relief for up to 72 hours after foot and ankle surgeries, making it a valuable option for outpatient procedures.

In two case studies involving complex surgeries, both patients experienced excellent control of postsurgical pain, highlighting the efficacy of EXPAREL® in managing pain without the risks associated with more extensive nerve blocks.

In a retrospective analysis of 575 subjects across 6 clinical trials, liposome bupivacaine showed a similar safety profile to both bupivacaine HCl and normal saline, with 76% of liposome bupivacaine recipients experiencing adverse events (AEs).

The most common AEs for liposome bupivacaine included nausea and hypesthesia, and serious AEs occurred in 8% of subjects, indicating that the side effects are likely related to the surgical procedure rather than the medication itself.

In a pilot study involving 25 pigs, subarachnoid administration of liposomal bupivacaine resulted in a longer duration of pain relief compared to standard bupivacaine hydrochloride, with effects lasting up to 32 hours for higher doses.

No signs of neurotoxicity were observed in any treatment group, suggesting that liposomal bupivacaine may be a safe option for extended analgesia in the neuraxial space, warranting further studies for potential human use.

Exparel™ (DepoFoam bupivacaine) provides a longer-lasting nerve blockade (240 minutes) compared to standard bupivacaine solutions, which lasted 120 minutes and 210 minutes, indicating its potential for improved pain management.

While Exparel™ showed slightly higher inflammation scores than standard bupivacaine solutions shortly after injection, it had similar myotoxicity levels and no neurotoxicity, suggesting it may be a safe option for local anesthesia, though monitoring for tissue reactions is recommended.
