In this Pain Exam Podcast episode, Dr. David Rosenblum discusses a journal club article on low volume neurolytic retrocrural celiac plexus blocks for visceral cancer pain. The study reviewed 507 patients with severe malignancy-related abdominal pain, with data retained for 455 patients at the 5-month mark. Dr. Rosenblum explains that the procedure involves injecting 3-5ml of 6% aqueous phenol at the T12-L1 level under fluoroscopic guidance, with an average procedure time of 16.3 minutes. The study found significant pain relief lasting up to six months, reduced opioid consumption, and improved quality of life for patients with primary abdominal cancer or metastatic disease. Dr. Rosenblum shares his personal experience with celiac plexus blocks, including the trans-aortic approach he trained on, and mentions his interest in ultrasound-guided approaches. He also announces upcoming teaching engagements at ASPN, Pain Week, and other conferences, as well as CME ultrasound courses available through nrappain.org.

Dr. Rosenblum mentions that a post about phenol in this community inspired today's podcast topic.
Journal Article Overview on Celiac Plexus Block
Dr. Rosenblum introduces a journal article on low volume neurolytic retrocrural celiac plexus block for visceral cancer pain, a retrospective review of 507 patients with severe malignancy-related abdominal pain. He explains that the study assessed pain relief provided by this procedure, its duration, reduction in daily opioid consumption, and quality of life improvements. The patients received neurolytic blocks without previous diagnostic blocks due to multiple comorbidities, which Dr. Rosenblum acknowledges is sometimes necessary with very sick patients despite the typical preference for diagnostic blocks before neurolysis.
Dr. Rosenblum's Personal Experience with Celiac Plexus Blocks
Dr. Rosenblum shares his personal training experience with trans-aortic celiac plexus blocks, where a needle is inserted through the aorta after confirming no plaques or aneurysms are present. He describes it as a safe and effective procedure despite sounding intimidating. He mentions he's only performed a handful of these procedures and doesn't do many now as an outpatient pain doctor.
Study Methods and Results
Dr. Rosenblum details the study methods, noting that of 507 patients studied, data for 455 was retained at the end of the review. Patients were evaluated before and after the neurolytic retrocrural celiac plexus block under fluoroscopic guidance. Assessment included procedure duration, pain scores (0-10 scale), daily opioid consumption, and quality of life improvement. Follow-up was completed six months after the procedure, showing improved pain scores, reduced opioid consumption, and better quality of life throughout the study period. Some pain returned during months 4-6 due to disease progression and the anticipated duration of the neurolytic agent. The study noted a 6.7% initial vascular contrast uptake during the procedure while using digital subtraction angiography with fluoroscopy.
Study Limitations and Conclusions
Dr. Rosenblum discusses the study's limitations, including the need for a larger sample size and a prospective trial with a control group, though he acknowledges this is unrealistic given the patient population. He mentions that a proven quality of life questionnaire would be beneficial, and that comparing alcohol, phenol, and RF thermocoagulation would be interesting to evaluate duration effects and side effects. The study concluded that low volume neurolytic retrocrural celiac plexus block with phenol is safe, providing up to six months of pain relief for abdominal pain due to primary malignancy or metastatic spread.
Detailed Procedure Technique
Dr. Rosenblum explains the detailed procedure technique used in the study. The retrocrural celiac plexus was targeted at L1 level with aim towards T12. Anterior and posterior radiographic imaging aligning the spinous process of T12-L1 junction was used with 15-20 degree oblique rotation. Local anesthetic (1% lidocaine with sodium bicarbonate) was infiltrated along the injection path. A 22 or 25 gauge 3.5-7 inch curved spinal needle was used depending on patient body habitus. Dr. Rosenblum notes he typically uses a 6-inch Chiba needle or 25 gauge spinal needle for such procedures.
Procedure Execution and Monitoring
Dr. Rosenblum continues describing the procedure, noting that the needle was advanced to the anterior border of T12-L1 under multiple imaging views. Contrast dye studies verified spread and location, with digital subtraction angiography used to check for intravascular uptake. A test dose of 1ml of 0.5% bupivacaine with epinephrine per site was administered, which Dr. Rosenblum finds interesting as he typically doesn't mix bupivacaine with epinephrine. After confirming no vascular uptake, 3-5ml of 6% aqueous phenol was injected in 1ml aliquots while communicating with the patient. The average procedure time was 16.3 minutes with minimal or no sedation. Patients remained prone for 30 minutes afterward to avoid neuroforaminal spread, as phenol is heavier and more viscous than alcohol.
Post-Procedure Care and Study Evaluation
Dr. Rosenblum explains that patients were monitored in recovery for one hour for adverse events and their ability to eat and void easily. They were discharged once hospital post-anesthetic criteria were met and received a follow-up call 24 hours later. Dr. Rosenblum praises the study and notes that the procedure looks similar to a lumbar sympathetic plexus block, which is also a sympathetic block.
Ultrasound Considerations and Alternative Approaches
Dr. Rosenblum shares his interest in ultrasound-guided celiac plexus blocks but acknowledges concerns about bowel perforation. He mentions a conversation with an interventional radiology colleague who suggested a transhepatic approach. Dr. Rosenblum recalls scanning a very thin patient where the aorta was easily visible and close to the anterior abdominal wall, making the celiac plexus potentially accessible if bowel perforation, liver bleeding, or gallbladder perforation could be avoided. He shares an experience with a patient suffering from severe pancreatitis pain who received temporary relief from a paravertebral thoracic nerve block at T8-T10, noting that paravertebral blocks provide some sympathetic spread.
Conclusion and Community Resource Reminder
Dr. Rosenblum concludes by recommending the article, noting its well-written analysis and graphs showing morphine consumption dropping over months following the procedure. He suggests neurolytic procedures are underutilized because they sound intimidating. He again encourages listeners to check out the community he created with separate chat rooms for regenerative medicine, regional anesthesia, and pain boards, where users can share keywords but not specific board questions. Dr. Rosenblum reminds listeners about upcoming courses and his website resources, mentions an upcoming PRP lecture, and asks for five-star reviews if listeners enjoy the podcast. The episode ends with a standard medical disclaimer.

Summary
Dr. David Rosenblum delivered a comprehensive lecture covering several key topics in pain management. He discussed his upcoming speaking engagements at PainWeek, ASPN and great upcoming meetings like the Latin American Pain Society, and other conferences. Dr. Rosenblum shared his extensive experience with PRP (Platelet-Rich Plasma) epidural injections, reviewing multiple research studies that support their efficacy. He highlighted three significant studies: a randomized control trial comparing PRP epidural injections to traditional treatments, a CT-guided epidural PRP study, and a 2025 meta-analysis comparing PRP to steroids. Dr. Rosenblum emphasized that PRP treatments are showing comparable or better results than traditional steroid injections, with potentially fewer required treatments and longer-lasting relief. He noted that while PRP is currently not covered by insurance, it represents a growing trend in 'natural' treatment approaches that patients increasingly prefer.
ChaptersIntroduction and Upcoming Events
Dr. Rosenblum announced his upcoming lectures at Pain Week focusing on ultrasound and regenerative medicine, followed by presentations at the Latin American Pain Society in Chile and the New York, New Jersey Pain Conference. He mentioned the SoMeDocs online pain conference accessible through nrappain.org, and upcoming ultrasound training sessions in New York City.
PRP Epidural Research Review
Dr. Rosenblum discussed a randomized control trial involving 30 patients receiving transforaminal epidural injections. The study showed that PRP patients demonstrated significant improvements in leg pain scores at 6, 12, and 24 weeks. He noted that while the study didn't use contrast, he personally prefers using contrast diluted with saline for better visualization.
CT-Guided Epidural Study Analysis
Dr. Rosenblum reviewed a study comparing CT-guided epidural PRP versus steroid injections, questioning the necessity of CT guidance. The study included 60 patients and showed similar results between PRP and steroid groups at six weeks, though he criticized the short follow-up period, noting that PRP typically takes months to show full effects.

Scrambler Therapy for Pain
mercredi 9 octobre 2024 • Durée 16:40
Dr. Rosenblum reviews the benefits of Scrambler Therapy for CRPS and Neuropathic Pain State.
What is Scrambler Therapy?
Efficacy of Scrambler Therapy for Neuropathic Pain
ST was introduced as a chronic pain relief method in 2003. That same year, Giuseppe Marineo published findings from a small clinical trial involving 11 terminal cancer patients suffering from drug-resistant chronic visceral pain, with all participants showing positive responses and significant reductions in pain scores. In a subsequent trial involving 226 patients with neuropathic pain, 80% reported a 50% reduction in pain. Since then, numerous case reports and studies have documented the use of ST for various pain types.
Evidence from these reports suggests that ST is effective for managing both acute and chronic pain from different causes. For instance, a child with acute mixed pain, resistant to pharmacological treatment, experienced significant relief after four ST sessions, with pain levels dropping from 5/10 to 0/10. Additionally, a 52-year-old woman with burning pain from her foot to knee, stemming from a right medullary acute hemorrhage and suffering for 12 years, reported immediate relief after ST. Her pain score decreased from 9/10 to 3/10 on the first day, and to 0/10 by the second day, remaining below 1 on the Visual Analog Scale (VAS) throughout the 10-day treatment period.
In terms of chronic pain, literature includes a case where a patient with shoulder joint pain and limited range of motion saw significant pain reduction and increased mobility after 10 sessions of ST. ST has shown considerable promise in treating severe pain conditions that are typically difficult to manage, such as complex regional pain syndrome and pain related to HIV.
Despite the encouraging results from these case studies, higher-quality evidence is necessary to establish the efficacy of ST, which could be obtained through extensive clinical trials, particularly focusing on chronic pain. Besides the aforementioned studies by Marineo and Sabato et al, additional trials have indicated that ST is an effective treatment for various chronic pain conditions, including low back pain, postherpetic pain, and neuropathic pain. For instance, a prospective study on chronic low back pain patients showed a significant decrease in VAS scores from 8.12 to 3.63 after six treatment days. Another trial involving 10 patients with postherpetic pain reported a drop in the average Numeric Rating Scale (NRS-11) score from 7.64 to 1.46 at baseline and 0.42 to 0.89 after one month, with benefits persisting at two and three months.
Hydrogen Therapy for Pain?
jeudi 12 septembre 2024 • Durée 11:17
PainExam Podcast Episode: An In-Depth Look at Hydrogen-Rich Water for Chronic Inflammatory Pain
In a recent episode of the PainExam podcast, Dr. David Rosenblum delves into an intriguing study published in the journal Antioxidants, exploring the therapeutic potential of hydrogen-rich water (HRW) in alleviating chronic inflammatory pain and associated mood disorders in mice. The study, conducted by Santiago Coral-Pérez and colleagues from the Institut d'Investigació Biomèdica Sant Pau and Universitat Autònoma de Barcelona, presents compelling evidence supporting the analgesic, antidepressant, and anxiolytic effects of HRW.
Study Overview
The study investigates the efficacy of HRW in treating nociceptive responses and affective disorders associated with chronic inflammatory pain. Using a mouse model induced by the subplantar injection of complete Freund's adjuvant (CFA), the researchers evaluated the impact of HRW on several parameters:
Nociceptive Responses: Mechanical allodynia and thermal hyperalgesia.
Affective Disorders: Depressive-like behaviors (measured by Tail Suspension Test and Forced Swimming Test) and anxiety-like behaviors (assessed using Elevated Plus Maze and Open Field tests).
Biomarker Analysis: Levels of oxidative stress, inflammatory, and apoptotic markers in the paws and amygdala.
Key Findings
1. Analgesic Effects:
Mechanical Allodynia and Thermal Hyperalgesia: The study found that both intraperitoneal and subplantar administration of HRW significantly reduced mechanical allodynia and thermal hyperalgesia in CFA-injected mice. Remarkably, the local (subplantar) administration showed greater effectiveness, achieving complete inhibition of nociceptive responses with just one day of treatment.
2. Antidepressant and Anxiolytic Effects:
Depressive-like Behaviors: HRW treatment normalized the increased immobility times in both the Tail Suspension Test and Forced Swimming Test, indicating potent antidepressant properties.
Anxiety-like Behaviors: HRW also reversed the anxiety-like behaviors in the Elevated Plus Maze and Open Field tests, showcasing its anxiolytic effects without impairing motor function.

ST has also demonstrated significant potential in treating neuropathic pain. In a prospective study of 45 patients with neuropathic pain lasting over three months, 28 experienced a decrease in Douleur Neuropathique en 4 questions (DN4) pain scores, with four patients stopping treatment early due to complete pain resolution. The mean baseline DN4 score dropped from 5.67 to 2.82 by the end of treatment. A pilot randomized trial involving 52 patients found that 21 out of 26 in the intervention group achieved complete pain relief.
While the findings from these studies, along with others that have been systematically analyzed, suggest strong evidence for the efficacy of ST, a definitive conclusion regarding its effectiveness has not yet been reached. A systematic review by Majithia et al concluded that while studies generally indicate ST results in pain reduction with lasting benefits, there are still gaps in the evidence.
This article aims to evaluate the research needs surrounding ST for cancer pain management. While Majithia et al focused on chronic pain across various conditions and noted specific evidence limitations, this study will concentrate on the effectiveness of ST for cancer-related pain. The objective is to identify gaps in the existing literature and provide recommendations for future research through a systematic review. We will specifically analyze the types and levels of evidence supporting the use of ST in managing cancer pain and determine what studies are necessary to enhance the evidence base.

3. Biochemical Pathways:
The study highlighted the significant role of the Nrf2/HO-1-NQO1 pathway in mediating the analgesic effects of HRW. Inhibitors targeting this pathway reversed the pain-relieving actions of HRW, underscoring its pivotal role.
Oxidative Stress and Inflammation: HRW treatment reduced the expression of oxidative (4-HNE), inflammatory (p-IKBα), and apoptotic (BAX) markers in both the paw and amygdala tissues, demonstrating its broad-spectrum protective effects.
Dr. Rosenblum emphasizes the potential of HRW as a novel therapeutic strategy for chronic inflammatory pain and its associated comorbidities. The study's findings suggest that HRW could offer a multifaceted approach, addressing both pain and mood disorders through its antioxidant, anti-inflammatory, and anti-apoptotic properties.
The episode concludes with a discussion on the broader implications of these findings for pain management, particularly in conditions where chronic inflammatory pain is prevalent. Dr. Rosenblum highlights the need for further clinical trials to validate these promising preclinical results and explore the potential of HRW in human subjects.
