Emergence agitation after intraoperative neurolytic celiac plexus block with alcohol: a case report

Background Emergence agitation after general anesthesia may cause several undesirable events in the clinic during patient anesthesia recovery, and acute alcohol intoxication, while rare in surgery, is one of the risk factors. Case presentation A 66-year-old male patient was found to have pancreatic tail neoplasm upon computed tomography (CT) examination. The surgeon planned to resect the pancreatic tail under general anesthesia. However, the surgeon found extensive tumor metastasis in the abdominal cavity, and thus performed a neurolytic celiac plexus block (NCPB) with 40 ml 95% ethyl alcohol and finished the surgery in approximately 1 h. Twenty minutes later, the patient was extubated and developed significant emergence agitation in the postoperative care unit, characterized by restlessness, uncontrollable movements, confusion and disorientation. The patient was flushed and febrile with an alcohol smell in his breath and was unable to follow commands. Patient symptoms were suspected to be due to acute alcohol intoxication. Thus, the patient was given 40 mg of propofol intravenously. Following treatment, the patient recovered with less confusion and disorientation after approximately 10 min. After treatment with propofol twice more, he regained consciousness, was calm and cooperative, had no pain, and could obey instructions approximately 1 h and 40 min following the last treatment. Following this treatment, the patient was transferred to the inpatient ward and felt well. Conclusions It is paramount to correctly identify the underlying cause of emergence agitation in order to successfully manage patient symptoms, since treatment plans vary between different etiological causes. Emergence agitation may be due to acute alcohol intoxication after intraoperative use of alcohol.

Celiac Plexus Block – An Old Technique with New Developments

BACKGROUND: Celiac plexus block (CPB) is an interventional technique known to be effective in the management of abdominal pain caused by pancreatic cancer. OBJECTIVE: To review the journey of CPB as an interventional analgesic technique from its inception to its current status in the field of cancer pain management. STUDY DESIGN: Descriptive review. METHODS: PubMed database was searched for celiac plexus block, celiac plexus neurolysis, and pancreatic cancer pain relief. Randomized control trials and case series with more than 10 patients were included. A second search was done from the references of all the included articles to add studies fulfilling the inclusion criteria which were missed in the first broad search. RESULTS: A total of 44 studies were included in this literature review. Available evidence through the years was categorized based on the imaging technique used to guide needle insertion and studies were tabulated based on study design, the number of patients included, the technique of CPB, and the conclusions drawn. LIMITATIONS: Meta-analysis of the available studies was not done because of heterogeneous nature of studies. CONCLUSION: Over the years, the majority of clinical trials have focused on fluoroscopy-guided CPB. Computed tomography-guided blockade of celiac plexus is the next choice among pain physicians and percutaneous ultrasound-guided CPB is a relatively new technique. The data generated over the years does not point to a single technique being the gold standard for CPB and choice of technique may be guided by the individual’s preference, familiarity with the technique, and institutional practice.
