Effect of Bupivacaine Liposome Injectable Suspension on Sensory Blockade and Analgesia for Dupuytren Contracture Release.

ABSTRACT:

Purpose

To study the efficacy of bupivacaine liposome injectable suspension in prolonging sensory blocks of the median and ulnar nerves for subjects with Dupuytren contracture release by collagenase injection. We hypothesized that combining liposome bupivacaine and bupivacaine hydrochloride would extend the duration of blocks without added complications.

Methods

We randomized 32 subjects scheduled for Dupuytren contracture release with collagenase Clostridium histolyticum injections to receive forearm blocks of the median and ulnar nerves with a mixture of 5 mL liposome bupivacaine 1.33% plus 2.5 mL bupivacaine hydrochloride 0.5% per nerve (n = 16) or 7.5 mL bupivacaine hydrochloride 0.5% alone per nerve (n = 16). Sensory block and analgesia were assessed through the first posttreatment week.

Results

Sensory block was nearly 4 times longer in subjects who received the liposome bupivacaine mixture compared with subjects who received bupivacaine hydrochloride alone. Most subjects (13 of 16) who received the liposome bupivacaine mixture had adequate analgesia for finger manipulation to rupture the cords, whereas most subjects (15 of 16) who received bupivacaine hydrochloride alone required additional anesthesia. Subjects in the liposome mixture group reported lower pain scores through the first 3 days after treatment. There were no serious side effects.

Conclusions

Addition of liposome bupivacaine to forearm blocks for Dupuytren contracture release prolonged sensory block and improved pain scores without increasing side effects or impairing hand function. Supplemental lidocaine injections for the painful phases of Dupuytren contracture release with collagenase C histolyticum injections were not required by most subjects who received liposome bupivacaine.

Project description:ImportanceOwing to its tendency to recur, Dupuytren contracture often requires multiple treatments, which places additional economic burden on health care. The likelihood of contracture recurrence varies not only with treatment but also with disease characteristics, such as contracture severity and location, but prior cost-effectiveness analyses of Dupuytren contracture treatments have not considered these patient-specific disease characteristics.ObjectiveTo identify the most cost-effective treatment regimen for patients with recurrent Dupuytren contracture.Design, setting, and participantsThis economic evaluation was conducted with state-transition microsimulation modeling using data from published studies and Medicare. A simulated cohort of 10 000 individuals with Dupuytren contracture was created. Patients could transition yearly between the following health states: symptom-free, symptomatic, and death. Available treatments were collagenase clostridium histolyticum injection, percutaneous needle aponeurotomy (PNA), and limited fasciectomy (LF); individuals randomly chose any treatment when symptomatic. Patients were limited to 3 rounds of treatment for a contracture affecting 1 joint, totaling 27 unique combinations. If the contracture recurred after 3 treatments, patients lived with the disease for the remainder of life.ExposuresPNA, collagenase clostridium histolyticum injection, or LF.Main outcomes and measuresQuality-adjusted life-years (QALYs), total costs (in US dollars), and incremental cost-effectiveness ratios (ICERs). A willingness-to-pay threshold of $100 000 per quality-adjusted life-year was used to assess cost-effectiveness.ResultsFor the base case scenario of a patient aged 60 years with recurrent, low-severity metacarpophalangeal (MCP) joint contracture, repeated PNA treatment was the only cost-effective treatment (2 PNA treatments followed by LF vs 3 PNA treatments, ICER [Monte Carlo SE]: $212 647/QALY [$36 000/QALY]). For recurrent high-severity MCP joint contractures, treatment regimens composed of PNA and LF were cost-effective (ICER [Monte Carlo SE], $93 932/QALY [$16 500/QALY]). LF was cost-effective for high-severity MCP joint contracture (ICER [Monte Carlo SE], $98 624/QALY [$26 233/QALY]). For recurrent proximal interphalangeal (PIP) joint contractures, PNA was the only cost-effective treatment, regardless of severity (eg, 2 PNA treatments followed by LF vs 3 PNA treatments for low-severity PIP joint contracture, ICER [Monte Carlo SE]: $263 726/QALY [$29 000/QALY]). Any combination with collagenase clostridium histolyticum injection compared with 3 PNA treatments had an ICER greater than $100 000 per QALY. Probabilistic sensitivity analysis estimated a 44%, 15%, 41%, and 52% chance of a regimen consisting of only PNA being cost-effective in low-severity MCP, high-severity MCP, low-severity PIP, and high-severity PIP joint contractures, respectively.Conclusions and relevanceThe results of this study suggest that LF is a cost-effective intervention for recurrent high-severity MCP joint contractures. For recurrent low-severity MCP joint contractures and PIP joint contractures of all severity levels, PNA was the only cost-effective intervention. Collagenase clostridium histolyticum injections were not a cost-effective intervention for recurrent Dupuytren contracture and should not be preferred over PNA or LF.

Project description:BackgroundTransversus abdominis plane (TAP) infiltration has been increasingly used for postsurgical analgesia in abdominal/pelvic procedures; however, duration/extent of analgesia with standard local anesthetics is limited. This pilot study assessed the preliminary efficacy and safety of two volumes of liposome bupivacaine administered via TAP infiltration in patients undergoing robotic laparoscopic prostatectomy.MethodsIn this single-center, open-label, prospective study, patients older than 18 years received TAP infiltration with liposome bupivacaine immediately after surgery. The first 12 patients received a total volume of 20 mL liposome bupivacaine (266 mg); the next 12 received 40 mL liposome bupivacaine (266 mg). The liposome bupivacaine was diluted with 0.9% normal saline. The primary efficacy measure was duration of analgesia, measured by time to first opioid administration. Secondary outcome measures included patient-assessed pain scores, opioid use, and opioid-related adverse events (AEs).ResultsTwenty-four patients received liposome bupivacaine (20 mL, n=12; 40 mL, n=12) and were included in the primary analysis. Three refused participation in a 10-day follow-up visit and did not complete the study. Median time to first opioid administration after surgery was 23 and 26 minutes for the 20 and 40 mL groups, respectively. Mean total amount of postsurgical opioids ranged from 25.4 to 27.3 mg; after hospital discharge to day 10, both groups required a mean of 0.7 oxycodone/acetaminophen tablets/day. Mean pain scores of 4.4 and 5.3 were reported at 1 hour and 3.1 and 3.9 at 2 hours postsurgery, with 20 and 40 mL doses, respectively. Neither group had mean scores higher than 3.0 at any further assessments. No opioid-related or treatment-related serious AEs were reported.ConclusionMedian time to first opioid administration did not differ between the two groups. No differences in secondary outcomes were observed on the basis of volume administered. These initial findings suggest further study of liposome bupivacaine administered via TAP infiltration as part of a multimodal analgesic regimen in laparoscopic robotic prostatectomy may be warranted.
