Rhomboid Intercostal and Subserratus Plane Block for Acute Pain Management after Abdominal Surgeries: A Narrative Review

Review

Author: Ly, Gianni H ; Dorius, Bradley ; Boullion, Jolie A ; Kaye, Alan D ; Shekoohi, Sahar ; Robinson, Christopher L ; Patel, Hirni ; Rogers, Brianna N ; Ahmadzadeh, Shahab ; Hollander, Alex V ; Thomassen, Austin S

PURPOSE OF REVIEW:

The rhomboid intercostal and subserratus plane (RISS) block is an effective, safer alternative for managing postoperative acute pain following abdominal surgeries. The RISS block offers several advantages over traditional approaches, including reduced incidence of puncture-related complications, lower rates of systemic opioid consumption, and more consistent analgesic coverage of lower thoracic dermatomes.

RECENT FINDINGS:

Despite a favorable safety profile, the RISS block carries potential risks, such as pneumothorax and local anesthetic systemic toxicity, particularly when long-acting anesthetics such as bupivacaine or ropivacaine are used. Careful administration with ultrasound guidance minimizes these risks, enhancing patient safety. Compared to epidural and paravertebral blocks, RISS is associated with fewer instances of nerve damage, hemodynamic instability, and bleeding. Research suggests that RISS not only improves postoperative pain scores, but also extends duration of analgesic effect, reducing total opioid use by nearly 40%.

CONCLUSION:

Future directions include clinical trials to validate efficacy across diverse patient populations, comparative studies with other regional blocks, and evaluations of long-term outcomes. Expanding our understanding of RISS block application may help advance multimodal pain management protocols, underscoring potential to improve recovery, reduce opioid dependency, and elevate patient quality of life in postoperative settings.

Postoperative analgesia with morphine promoting microglial activation and neuroinflammation induced by surgery aggravates perioperative neurocognitive dysfunction in aged mice

Review

Author: Xie, Liping ; Shao, Xiuzhi ; Ge, Mingyue ; Zhai, Jingwen

Introduction:

Perioperative neurocognitive dysfunction (PND) is a significant challenge for patients who need surgery worldwide. Morphine can trigger an intense inflammatory reaction in the central nervous system (CNS) at the same time as analgesia, thus adverse effects aggravating PND. Microglia polarization is closely involved in the regulation of neuroinflammation and the TLR4/MyD88/NF-κB signaling pathway. However, the mechanisms of morphine analgesia aggravating PND impairment remain unclear.

Methods:

Tibial fracture surgery was performed in 18 months old male C57BL/6 J mice to mimic human orthopedic surgery and postoperative analgesia with morphine hypodermic or ropivacaine. Levels of inflammatory factors in the hippocampus, activation, and phenotype of microglia, an essential protein of TLR4/MyD88/NF-κB signal pathway, synaptic plasticity, and hippocampal-dependent memory function were evaluated after surgery and postoperative analgesia.

Results:

Morphine postoperative analgesia increased the expression of pro-inflammatory cytokines IL-1 β, IL-6, and TNF-α, decreased the level of anti-inflammatory IL-10, aggravated the activation of microglia and the destruction of synaptic plasticity in the hippocampus, resulting in hippocampal neuron loss, a significant decrease in the number of synapses and cognitive impairment in aged mice. In addition, the aggravation of neuroinflammatory response and the activation of microglia may be mediated by TLR4/MyD88/NF- κ B signal pathway.

Conclusion:

Our results demonstrate that morphine postoperative analgesia may aggravate microglia activation and neuroinflammation in the hippocampus by regulating the TLR4/MyD88/NF- κ B signal pathway and inhibiting the synaptic plasticity hippocampal neurons. It aggravated the acute cognitive decline and cognitive impairment after tibial fracture in elderly mice.

Continuous regional anesthesia with erector spinae plane catheters for patients with multiple rib fractures

Article

Author: Driver, Brian E ; Rauschenbach, Anthony ; Nguyen, Michelle ; Smoot, William ; Lee, Dan ; Dreyfuss, Andrea ; Richardson, Chad J ; Reardon, Robert F ; Martel, Marc L

INTRODUCTION:

Opioids are commonly used for acute pain management in patients with rib fractures, but their use poses known risks of addiction and respiratory depression. Regional anesthesia, namely the erector spinae plane(ESP) block, has shown promise as an alternative to opioids in case series. Our aim was to evaluate the efficacy and safety of continuous ropivacaine infusion ESP catheters performed by emergency physicians (EP) for patients with multiple unilateral rib fractures.

METHODS:

This retrospective case control study identified polytrauma patients with rib fractures in a 1-year period between 2019 and 2020 who had an ESP catheter placed by EP. The control group consisted of polytrauma patients who did not receive regional anesthesia and were matched by number of rib fractures and age. Our primary outcome was opioid use in morphine milligram equivalents per day (MMED). We compared MMED before and after catheter placement in the treatment group and overall MMED between the control and catheter group. Secondary outcomes included length of hospitalization, rate of intubation, and complications. Subgroup analysis of the same variables was performed on the group of patients whose only injury was rib fractures.

RESULTS:

The catheter group included 89 patients, matched with an equal number in the control group. Opioid use decreased from 89 to 67 MMED after catheter placement in the treatment group (P = 0.003). Overall opioid use during hospitalization did not significantly differ between treatment and control groups (P = 0.57). There was a trend toward fewer days of mechanical ventilation and shorter hospital length of stay in the catheter group in patients with isolated rib fractures, but neither of these trends reached statistical significance.

CONCLUSION:

Opioid use decreased after ESP catheter implementation and there were no meaningful complications. Although there was no significant difference in opioid use between groups, ESP catheter placement and continuous regional anesthesia by EP is a safe, reasonable adjunct to treat pain from rib fractures.

("Eupraxia" or the "Company") (NASDAQ: EPRX) (TSX: EPRX), a clinical-stage biotechnology company, today unveiled new pharmacokinetic ("PK") data from its Phase 2a Eosinophilic Esophagitis ("EoE") program. Management believes these data underscore the unique capabilities of Eupraxia's proprietary DiffuSphere™ platform technology, which aims to provide precise, localized, safe, and effective long-lasting drug delivery. Most conventional drugs release in a pattern characterized by steep peaks and rapid declines in drug concentration, where peaks often lead to negative side effects, and troughs result in reduced efficacy. In contrast, DiffuSphere™ is a unique microsphere that is designed to enable precise drug release into target tissues with a flat, stable, and long-lasting profile, minimizing potential adverse events associated with high-dose systemic delivery. What sets DiffuSphere™ apart is its composition: a pure drug crystal encased in a microns-thick polymer shell. Eupraxia's proprietary technology uses this polymer to precisely control a drug's release, ensuring high drug concentrations in the target tissues while minimizing exposure to the rest of the body. This innovative approach has been observed in Eupraxia's clinical programs, demonstrating precision, tolerability, and extended duration of delivering fluticasone propionate ("FP") directly to the intended tissues for EoE and knee osteoarthritis ("OA") patients. "Our DiffuSphere™ platform is designed to enable us to deliver the right drug to the right place at the right time with a precise PK profile, aiming to ensure patients receive safe, effective, and durable treatment," said Eupraxia's CEO, Dr. James Helliwell. "We are excited about the broad-based potential of DiffuSphere™. The clinical data from EoE and OA, combined with our extensive non-clinical data showing precise delivery of numerous drugs in a broad array of target tissues, reinforces our optimism." RESOLVE Trial Demonstrates Compelling Pharmacokinetics in the Esophagus DiffuSphere™, when injected into the esophageal wall (submucosa), shows a treatment duration exceeding six months from a single injection, with predictable dose control. In Cohort 1 (4 mg FP), a steady level of 1.5 pg/ml was maintained for at least six months. In Cohort 5 (48 mg FP), 10pg/ml was observed at three months. With this steady, localized, and long-lasting delivery, key EoE disease measures, including patient symptoms, esophageal tissue health, and eosinophil counts, improved. This impact of the DiffuSphere™ technology was clearly demonstrated in a non-clinical study in pigs comparing local and systemic levels of FP after intraesophageal injection of EP-104GI versus oral gavage. Presented at the American College of Gastroenterology meeting (poster), the study revealed that esophageal tissue levels of fluticasone were more than 1000 times higher in the EP-104GI group compared to the oral gavage group, even at distances of several centimeters from the injection sites. Moreover, despite significantly higher local concentrations, systemic levels of fluticasone in the plasma were lower in the EP-104IAR group than in the oral gavage group. This underscores the targeted and precise delivery capabilities of the DiffuSphere™ technology. DiffuSphere™ in the Joint DiffuSphere™ is the technology behind Eupraxia's EP-104IAR for treating OA. In Eupraxia's Phase 2b clinical study, EP-104IAR was well tolerated and showed significantly durable efficacy over placebo. The trial results were recently published in The Lancet, reinforcing the preclinical work previously published in Cartilage. The Phase 2b data showed that EP-104IAR effectively controlled patients' pain for up to 22 weeks (as measured by OARSI Strict Responders) and was well-tolerated. This includes no disruption to blood glucose metabolism (a key factor for diabetics, who comprise almost 40% of the OA population) or adrenal function, which have been reported with other steroid formulations used in this indication. DiffuSphere™ in Other Applications Eupraxia has successfully applied DiffuSphere™ across multiple anatomic locations and drug classes. In preclinical studies, DiffuSphere™ has demonstrated its precise, steady, and tunable delivery traits in intraarticular, intraesophageal, intravitreal, epidural, peritoneal, and subcutaneous applications. Additionally, Eupraxia has demonstrated DiffuSphere's™ capability with local anesthetics such as ropivacaine and various anti-infective agents. The new data in EOE patients further supports DiffuSphere's™ ability to deliver drugs with local precision: stable drug delivery without peaks and troughs, and a customizable duration to fit the clinical indication. This reinforces Eupraxia's confidence in the platform's broad potential. About Eosinophilic Esophagitis (EOE) and the RESOLVE Trial EoE is an inflammatory-mediated disease in which white blood cells migrate into and become trapped in the esophagus, creating pain and difficulty with swallowing food. According to market research from Clearview Healthcare Partners, EoE affects more than 450,000 people in the United States and has been identified by the American Gastroenterological Association as rapidly increasing in both incidence and prevalence. Impacts from both symptoms and interventions frequently lead to mental health issues, compounding the disease burden of EoE for both the healthcare system and the individual. RESOLVE is a Phase 1b/2a, multicenter, open-label, dose-escalation study to evaluate the safety, tolerability, pharmacokinetics, and efficacy of EP-104GI in adults with histologically confirmed, active EoE. EP-104GI is administered as a single dose via four to 20 injections into the esophageal wall. Dose escalations increase the dose per site and/or number of sites. Participants in the first through the fourth cohorts will be assessed for up to 24 weeks, and cohorts five and above will be assessed for up to 52 weeks. About Osteoarthritis (OA) Eupraxia's OA product candidate, EP-104IAR, is designed to meet the significant unmet medical need and market demand for long-lasting disease relief in multiple indications, benefitting from highly localized and longer delivery of corticosteroids. The lead indication is for pain relief in knee OA. The U.S. Centers for Disease Control and Prevention estimates knee OA affects more than 30 million people in the U.S. alone. This includes 14 million that suffer from knee pain or some form of disability. Knee OA is also associated with depression and loss of sleep, which can significantly affect quality of life. With EP-104IAR, Eupraxia hopes to change the way knee OA pain is treated. The Company believes current therapies are challenged by poor safety, inadequate efficacy and/or limited duration of activity. Corticosteroids are one of only two drug classes strongly recommended by the American College of Rheumatology and the Arthritis Foundation for treating knee OA pain. Currently approved corticosteroids are very effective at reducing pain for a short duration late in the disease but can expose the body to unwanted local and systemic side effects. EP-104IAR is designed to prolong the duration of pain relief with fewer adverse events. It encapsulates a highly potent corticosteroid (fluticasone propionate) within a microns-thin polymer membrane, part of Eupraxia's patented technology platform. Injected into the knee, EP-104IAR is designed to diffuse the corticosteroid slowly into the knee joint providing local therapeutic concentrations for up to six months. This has the potential dual advantage of providing longer duration of pain relief with fewer systemic adverse events. A robust safety and tolerability profile would also benefit the estimated 70% of knee OA patients that experience pain in both knees by allowing simultaneous treatment of both affected joints. EP-104IAR has also been designed to incorporate additional advantages, such as physician convenience, targeting a long shelf life, no refrigeration and easy integration into existing delivery techniques. About Eupraxia Pharmaceuticals Inc. Eupraxia is a clinical-stage biotechnology company focused on developing locally delivered, extended-release products that have the potential to address therapeutic areas with high unmet medical need. DiffuSphere™, a proprietary, polymer-based micro-sphere technology, is designed to facilitate targeted drug delivery of both existing and novel drugs. The technology is designed to support extended duration of effect and delivery of drugs in a hyper-localized fashion, targeting only the tissues that physicians are wanting to treat. We believe the potential for fewer adverse events may be achieved through the precision targeting and the stable and flat delivery of the active ingredient when using the DiffuSphere™ technology, versus the peaks and troughs seen with more traditional drug delivery methods. The precision of Eupraxia's DiffuSphere™ technology platform has the potential to augment and transform existing FDA-approved drugs to improve their safety, tolerability, efficacy and duration of effect. The potential uses in therapeutic areas may go beyond pain and inflammatory gastrointestinal disease, where Eupraxia currently is developing advanced treatments, to also be applicable in oncology, infectious disease and other critical disease areas. Eupraxia's EP-104GI is currently in a Phase 1b/2a trial, the RESOLVE trial, for the treatment of EoE. EP-104GI is administered as an injection into the esophageal wall, providing local delivery of drug. This is a unique treatment approach for EoE. Eupraxia also recently completed a Phase 2b clinical trial (SPRINGBOARD) of EP-104IAR for the treatment of pain due to knee osteoarthritis. The trial met its primary endpoint and three of the four secondary endpoints. In addition, Eupraxia is developing a pipeline of later and earlier-stage long-acting formulations. Potential pipeline indications include candidates for other inflammatory joint indications and oncology, each designed to improve on the activity and tolerability of currently approved drugs.
