Question:
A surgeon decides to operate a patient under epidural anesthesia. 3% Xylocaine with adrenaline is used for administering epidural anesthesia. The patient suddenly develops hypotension after 3 minutes of administration. What is the most likely cause for this? 

Options:
{'A': 'Systemic absorption of the drug', 'B': 'Vasovagal effect', 'C': 'Allergy to the drug preparation', 'D': 'Penetration into the subarachnoid space'}'

[2025-10-01T02:37:12.215324] [PI reasoning] **Exploring severe hypotension cases**

The search results highlight case reports of severe hypotension after accidental subdural/subarachnoid injections, which is essential to cite. A sudden drop in blood pressure just three minutes after an epidural injection suggests unintentional intrathecal spread causing high spinal block due to sympathetic blockade. I’m considering using Richardson's work from 1996, noting some uncertainty about the year. I’ll double-check to ensure I'm accurate before finalizing the citation.
