What You Need to Know Before You Apply

What is the purpose of this trial?

This project is a multicenter, three armed, prospective randomized control trial studying the effectiveness of a long-acting local anesthetic "cocktail" in patients undergoing operative fixation of ankle fractures.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, you must be able to take the standard post-operative pain regimen, which includes gabapentin, oxycodone, acetaminophen, and ibuprofen.

Is the treatment generally safe for humans?

Liposomal bupivacaine, a long-acting form of bupivacaine, has been shown to be safe for pain management in surgeries like breast augmentation and third molar extraction. However, there have been severe adverse reactions, including fatalities, associated with bupivacaine and etidocaine, highlighting the importance of being aware of potential risks. ^{1 2 3 4 5}

How is the drug used for pain control in ankle fractures different from other treatments?

The drug, liposomal bupivacaine, is unique because it provides long-lasting pain relief for up to 72 hours with just a single injection, unlike standard treatments that may require more frequent dosing. ^{1 6 7 8 9}

What data supports the effectiveness of the drug liposomal bupivacaine for pain control in ankle fractures?

Liposomal bupivacaine, a slow-releasing form of bupivacaine, has been shown to be effective for managing postsurgical pain, providing relief for up to 72 hours with a single application. However, a comprehensive review of trials found that liposomal bupivacaine often does not outperform standard local anesthetics like unencapsulated bupivacaine or ropivacaine, especially when used in peripheral nerve blocks. ^{1 9 10 11 12}

Published Research Related to This Trial

Liposomal bupivacaine offers effective and safe pain management after surgery, providing long-lasting local analgesia for up to 72 hours with a single injection.

This slow-releasing formulation enhances patient satisfaction by reducing the need for additional pain medications following procedures like total ankle arthroplasties.

Administration technique of liposomal bupivacaine for total ankle arthroplasty. Matsumoto, T., Parekh, SG.[2017]

In a study of 76 patients undergoing surgery for ankle fractures, the use of liposomal bupivacaine significantly reduced postoperative pain scores compared to a placebo, with effects lasting up to 2 weeks after surgery.

Patients receiving liposomal bupivacaine required less Percocet for pain management in the first 4 hours post-surgery, indicating its efficacy in improving pain control immediately after the procedure.

In a study of 50 patients undergoing vaginal reconstructive surgery, liposomal bupivacaine (LB) did not show any significant advantage over plain bupivacaine in terms of postoperative pain control, narcotic use, or length of hospital stay.

Despite LB's higher cost, the results indicate that it is not more effective than plain bupivacaine for managing pain after surgery, suggesting a need for further research to find the best pain management strategies.

In a study of 105 patients undergoing posterior spinal surgery, the use of liposomal bupivacaine (LB) significantly reduced patient-reported pain levels at 24 hours and 48-72 hours post-surgery compared to a control group, indicating its efficacy as a local analgesic.

Patients receiving LB also experienced a shorter average length of hospital stay (1.85 days) compared to those who did not receive LB (2.68 days), suggesting that LB may contribute to improved recovery outcomes.

A review of 76 randomized controlled trials found that only 11% showed a significant benefit of liposomal bupivacaine over standard bupivacaine or ropivacaine for postoperative pain control.

The majority of trials indicated that unencapsulated bupivacaine provided better pain relief than liposomal bupivacaine, suggesting that routine use of liposomal bupivacaine may not be justified based on current evidence.

In a study of 34 patients undergoing breast augmentation, liposomal bupivacaine provided statistically significant lower pain scores compared to standard bupivacaine at multiple time points post-surgery, indicating it may offer better pain control.

Despite the statistical significance, the differences in pain relief were small, and 70% of patients felt the additional cost of liposomal bupivacaine was not justified by the benefits, suggesting limited clinical relevance.

Bupivacaine and etidocaine, long-acting local anesthetics introduced in the 1980s, have been associated with severe adverse reactions, including fatalities, even with small doses, highlighting their potential risks.

Animal studies indicate that bupivacaine and etidocaine have higher systemic toxicity compared to lidocaine, leading to serious central nervous system and cardiovascular issues, which can result in life-threatening conditions.

A systematic review of 13 randomized controlled trials found that liposomal bupivacaine may provide longer pain relief compared to conventional local anesthetics in certain regional anesthesia techniques, particularly in transversus abdominis plane (TAP) blocks, with 3 out of 5 studies showing extended analgesia.

However, the evidence is not consistent across all studies, as some techniques did not demonstrate significant differences in analgesic duration, indicating that more research is needed to establish the efficacy of liposomal bupivacaine compared to standard bupivacaine.

In a phase 3 study involving 150 subjects undergoing third molar extraction, liposomal bupivacaine (LB) showed a significant reduction in pain scores compared to placebo in the per-protocol population, indicating its potential efficacy as a pain management option.

Despite the promising results, the primary efficacy analysis did not show significant differences due to protocol violations, suggesting that further studies are needed to confirm LB's effectiveness and ensure adherence to study protocols.

In a study involving 52 patients undergoing wrist surgeries, liposomal bupivacaine and standard bupivacaine HCl provided similar pain control and opioid usage in the first four postoperative days.

There were no significant differences in pain scores or opioid requirements between the two anesthetics, indicating that liposomal bupivacaine does not offer a clear advantage over bupivacaine HCl for early postoperative pain management.

Patients receiving bupivacaine liposome (Exparel) reported significantly lower pain levels and consumed fewer opioid pills on the day of surgery compared to those receiving standard bupivacaine (Marcaine).

However, the benefits of Exparel in reducing pain and opioid use were not sustained beyond the day of surgery, as no significant differences were observed in pain levels or total opioid consumption in the following days.

Instilling 0.5% bupivacaine directly into the surgical wound before closure is a safe and effective method for significantly reducing postoperative foot pain.

This technique offers a practical alternative to oral narcotics and parenteral agents, minimizing side effects and the need for complex administration methods.
