BACKGROUND: Liposomal bupivacaine is reported to prolong the duration of analgesia when used for abdominal fascial plane blocks compared to plain local anesthetics; however, evidence from randomized trials is mixed. This meta-analysis aims to compare the analgesic effectiveness of liposomal bupivacaine to plain local anesthetics in adults receiving abdominal fascial plane blocks. METHODS: Randomized trials comparing liposomal bupivacaine and plain (nonliposomal) local anesthetics in abdominal fascial plane blocks were sought...

BACKGROUND: Peripheral nerve blocks (PNBs) are used in multiple surgical fields to provide a high level of regional pain relief with a favorable adverse effect profile. Peripheral nerve blocks aim to decrease overall perioperative pain and lower systemic analgesic requirements. Short-acting anesthetic agents are commonly given as single-injection PNBs for pain relief, typically lasting less than 24 hours. Liposomal bupivacaine is a newer anesthetic formulation lasting up to 72 hours as a single-injection PNB and may allow patients to recover postoperatively with a lower need for opioid analgesics...

Purpose This retrospective cohort explores the efficacy of regional shoulder blocks using Exparel™ in patients undergoing total shoulder arthroplasty (TSA)/reverse total shoulder arthroplasty (RSA) to reduce total opioid prescription, refills, and length of stay in the acute care setting. Methods Patients who underwent TSA/RSA by a single surgeon in a three-year period were evaluated. Patients in the case group received liposomal bupivacaine 1.3% brachial plexus block while the control group received ropivacaine 0...

BACKGROUND: Despite improvements in drug therapy and treatment of lumbar spinal disorders, dependence on opioid medication for postoperative pain control remains a concern nationwide. This study assessed the ability to diminish the reliance on opioid medication postoperatively with the Food and Drug Administration-approved local anesthetic liposomal bupivacaine in open posterior lumbar decompression and fusion procedures. In addition, the possible effects of this modality on other parameters were studied regarding patients and their recovery...

BACKGROUND: Little is known about the pharmacodynamic characteristics of liposomal bupivacaine. Hypothesizing that we would not identify pharmacodynamic differences from plain bupivacaine during the initial period after administration, but would find better long-term pharmacodynamic characteristics, we designed a randomized, controlled, triple-blinded, single-center study in volunteers. METHODS: Volunteers aged 18 to 55 years (body mass index: 18 to 35 kg/m²) received two ulnar nerve blocks under ultrasound guidance...

INTRODUCTION: Lumbar Erector Spinae (ESP) field blocks have become a common postoperative treatment for surgical pain. The use of long-acting medications like liposomal bupivacaine (Exparel) has become a major component of multi-modal postsurgical pain control. Traditionally ESP injections have been performed using ultrasound (U/S) guidance by an anesthesiologist. Spine surgeons have begun to utilize these liposomal injections in their procedures for post-operative pain management. Our study describes a fluoroscopic guided ESP field block technique which provides reproducible muscular coverage and pain control for spine surgery...

BACKGROUND: Thoracic epidural analgesia (TEA) and liposomal bupivacaine (LB) are two methods used for postoperative pain control after thoracic surgery. Some studies have compared LB to standard bupivacaine. However, data comparing the outcomes of LB to TEA after minimally invasive lung resection is limited. Therefore, the objective of our study was to compare postoperative pain, opioid usage, and outcomes between patients who received TEA vs . LB. METHODS: We conducted a retrospective chart review of patients who underwent minimally invasive lung resections over an 8-month period...

Optimal pain management after open abdominal surgery is essential but can be difficult to achieve. The effects of inadequate analgesia go beyond the first few postoperative days; severe acute postoperative pain may contribute to the development of chronic postsurgical pain. Thoracic epidural analgesia is a traditional approach to the management of acute pain after open abdominal surgery but has multiple possible contraindications and can be technically challenging. In our hospital, we typically offer ultrasound-guided rectus sheath blocks with catheters when epidural analgesia is not feasible...

Opioid-sparing pain management is an integral component of enhanced recovery after colonic and rectal surgery. In our hospital, rectus sheath catheters (RSCs) are routinely placed during emergency laparotomy for colorectal procedures to allow a postoperative compartmental block of the surgical site with repeated doses of bupivacaine. However, RSCs require a significant amount of clinical nursing time to maintain and 'top-up'. We present a quality improvement project in which we administered single-shot liposomal bupivacaine (LB) intraoperatively as an alternative to bolus doses of conventional bupivacaine delivered through RSCs...

BACKGROUND: Poorly controlled postoperative pain results in prolonged length of stay (LOS). The use of liposome bupivacaine injectable suspension (LB) for postoperative pain control is a relatively recent practice. PURPOSE: The purpose of this study was to investigate the following. In patients undergoing open reduction and internal fixation of mandibular fracture(s), does the use of LB reduce LOS compared with regular bupivacaine? STUDY DESIGN, SETTING, SAMPLE: We implemented a retrospective cohort study of consecutive patients with mandibular fracture(s) presented to Grady Memorial Hospital in Atlanta, GA, from January 2021 to January 2022...

OBJECTIVE: The objectives of the study were to compare the clinical efficacy and adverse effects of two analgesic protocols consisting of bupivacaine liposome injectable solution (BLIS) and 0.5% bupivacaine and fentanyl for postsurgical analgesia in dogs undergoing limb amputation. STUDY DESIGN: Randomized, double-blind, prospective, controlled, intent-to-treat, clinical noninferiority trial. ANIMALS: Forty client-owned dogs. METHODS: Dogs undergoing amputation were randomly assigned to either the BLIS or control group...

STUDY OBJECTIVE: To investigate the efficacy, safety, pharmacodynamics, and pharmacokinetics of liposomal bupivacaine (LB) administered via ultrasound-guided sciatic nerve block in the popliteal fossa in participants undergoing bunionectomy. DESIGN: Two-part, randomized, double-blind, active-controlled trial (NCT05157841). SETTING: Operating room, postanesthesia care unit, and health care facility (6 sites).

OBJECTIVE: To compare the effectiveness of preoperative bupivacaine inferotemporal retrobulbar blocks to postoperative liposome-encapsulated bupivacaine (Nocita) line blocks for analgesia following enucleation. ANIMALS: 39 client-owned dogs (40 eyes) presenting to the Ophthalmology Service for enucleation. METHODS: Dogs were randomly assigned to receive either a preoperative inferotemporal retrobulbar block with 0.5% bupivacaine or a peri-incisional line block with liposome-encapsulated bupivacaine (Nocita) at closure...

PURPOSE: To investigate the association of patient race and ethnicity with postanesthesia care unit (PACU) outcomes in common, noncardiac surgeries requiring general anesthesia. DESIGN: Single tertiary care academic medical center retrospective matched cohort. METHODS: We matched 1:1 1836 adult patients by race and/or ethnicity undergoing common surgeries. We compared racial and ethnic minority populations (62 American Indian, 250 Asian, 315 Black or African American, 281 Hispanic, and 10 Pacific Islander patients) to 918 non-Hispanic White patients...

Local anesthetics are effective in relieving pain, but their duration of action is short. Therefore, the development of injectable sustained release systems to prolong the effect of local anesthetics has been of interest. In such systems delivering conventional local anesthetics, it has been challenging to achieve long durations of effect, particularly without incurring tissue toxicity. To overcome these challenges, we created a platform comprising a protein hydrogel incorporating hydrophobic local anesthetic (bupivacaine) nanoparticles...

BACKGROUND: Transversus Abdominis Plane (TAP) blocks improve pain control and reduce narcotic medication requirements in various surgical procedures. Liposomal bupivacaine may provide more sustained analgesia. This study compares pain related outcomes between standard bupivacaine and liposomal bupivacaine TAP blocks after autologous breast reconstruction. METHODS: Prospective single-center, single-blinded, randomized controlled trial between March 2021 and December 2022...
