The celiac plexus block (CPB) is an interventional technique used to manage intractable abdominal pain that does not respond to less aggressive analgesic interventions. This block targets visceral afferent pain fibers from several abdominal organs and is particularly beneficial for patients with malignant and benign disorders. Several approaches to CPB have been described, including the posterior and anterior para-aortic approaches. These techniques are the most commonly used. However, it is imperative to acknowledge that while CPB yields considerable advantages, it carries inherent risks and potential complications, encompassing orthostatic hypotension, tissue injury, bleeding, infection, and other concerns. Despite these potential issues, CPB with neurolysis has been found to significantly improve pain in patients with pancreatic cancer, reduce overall opioid consumption, and enhance patient satisfaction. This activity outlines the procedure, indications, and potential complications of a celiac plexus block. Healthcare practitioners explore the complexities of CPB, addressing patient selection, approach choices (posterior or anterior para-aortic), and potential complications. Participants will gain insights into improving patient outcomes, reducing opioid consumption, and increasing satisfaction. Thiscourse underscores the collaborative role of the interprofessional team in CPB procedures. Effective communication, coordinated care, and shared decision-making are vital components. Objectives: Identify suitable candidates for celiac plexus block based on a comprehensive evaluation of patients with intractable abdominal pain, considering underlying etiologies such as malignancies and chronic pancreatitis. Differentiate between the posterior and anterior para-aortic approaches for celiac plexus block, considering patient-specific factors and clinical indications to choose the most appropriate technique. Assess and manage potential complications from celiac plexus block, including orthostatic hypotension, injury to surrounding tissues, and local anesthetic toxicity, with prompt and effective intervention. Collaborate with the interprofessional team to develop strategies for identifying, mitigating, and managing potential complications related to celiac plexus block, emphasizing proactive measures to enhance patient safety and well-being.

First introduced as a technique for providing surgical anesthesia in upper abdominal procedures, the celiac plexus block (CPB) has been used for almost a century. Functioning as a versatile multimodal adjunct in the management of abdominal visceral pain, the CPB targets the intricate celiac plexus, encompassing the celiac, superior mesenteric, and aorticorenal ganglia, which form an extensive neural network, often referred to as the solar plexus.[1] This network orchestrates autonomic innervation for various abdominal organs, including the liver, gallbladder, stomach, pancreas, spleen, kidneys, small bowel, and the initial two-thirds of the large bowel.[2] Primarily, the CPB is deployed to address afferent nociceptive fibers, rendering it valuable as both a diagnostic and therapeutic tool for managing intraabdominal pain.[1][3] CPB is indicated in cases of intractable abdominal pain refractory to less aggressive analgesic interventions and is mainly used in the palliation of pain related to malignant and benign neoplastic conditions affecting abdominal organs, with pancreatic cancer the most prevalent. However, using CPB in chronic pancreatitis remains a subject of debate.[1][4][5]

Complications arising from CPB, although infrequent, are recognized within the medical literature. Nevertheless, there remains a potential for the procedure to yield suboptimal outcomes. The most common complication is orthostatic hypotension, which can be mitigated by implementing appropriate hydration strategies. Beyond orthostatic hypotension, many complications may manifest, even when guided by image-assisted techniques. These complications may encompass, but are not limited to, the following: Intravascular injection of the anesthetic agent Injury to surrounding tissues, including nerve roots, vasculature, muscles, and nearby organs Paresthesias Intrathecal or epidural injection of the anesthetic agent Bleeding, including retroperitoneal hematoma formation Pneumothorax Infection with or without abscess formation Paraplegia Local anesthetic toxicity with the central nervous system and cardiovascular compromise [21] Furthermore, diarrhea represents a recognized complication of CPB; this arises from the profound sympathetic denervation of the gastrointestinal tract, which, in turn, engenders heightened peristalsis due to unopposed parasympathetic nervous system activity.[22]

When administering a CPB, collaborating with a multidisciplinary healthcare team comprising physicians, nurses, pharmacists, and other health professionals is pivotal in ensuring patient-centered care and optimizing treatment outcomes. Effective interprofessional communication and collaboration are essential components of this endeavor. The primary care providers, including physicians, physician assistants, and nurse practitioners, must consult the appropriate clinicians who perform this procedure for patients who would benefit from a CPB. Physicians, primarily interventional radiologists or anesthesiologists, must possess the technical skills and a thorough understanding of the CPB procedure, including patient selection, anatomical landmarks, and the choice of anesthetic agents or neurolytic substances. Nurses are tasked with patient assessment, preparation, and monitoring during and after the procedure, emphasizing patient comfort and safety. They do this partly by ensuring all consents are signed after specific risks, benefits, and expectations have been explained in detail to the patient and a proper procedural timeout is performed. The patient’s name, date of birth, pertinent allergies, and procedure should be confirmed by all providers and the patient. Site verification and laterality must be confirmed. Implementing guidelines and checklists has proven to reduce the occurrence of adverse outcomes such as surgeon-anesthesiologist miscommunications and wrong-site or wrong-side regional anesthesia procedures.[24][25] Pharmacists contribute by ensuring appropriate medication management and minimizing the risk of drug interactions or complications.

Ethical considerations are paramount, and healthcare professionals must engage in shared decision-making with patients, respecting their autonomy and providing comprehensive information about the procedure’s risks and benefits. Additionally, care coordination is critical to ensure seamless transitions between pre-procedure evaluation, the CPB itself, and post-procedure follow-up. The team collaboratively addresses any complications or adverse events promptly, with a focus on patient-centered care and the overall enhancement of team performance. By synergizing their skills, strategies, ethical principles, and responsibilities, these healthcare professionals work together to facilitate safe, effective, and patient-centered CPB, ultimately improving patient outcomes and fostering a culture of excellence in healthcare delivery.
