: Many French teaching hospitals publish their internal protocols as PDFs for medical students and practitioners.
: A critical section in these guides is the list of absolute contraindications (e.g., coagulation disorders, local infection) and the mandatory "safety check" protocols to follow before the procedure.
: The PDFs provide detailed technical steps for performing infiltrations under fluoroscopic (X-ray) or CT guidance. This ensures the needle is perfectly positioned in the epidural space or near the nerve root, reducing the risk of vascular or neurological injury.
