Those patients scheduled for afternoon procedures should eat a normal breakfast (. cereal, toast, etc.) and a light lunch, such as a sandwich and soup. You may take your regularly scheduled medications; however, there are some exceptions. Hold any anticoagulants, such as Coumadin, Heparin or Lovenox, for three days prior to your procedure. Hold Glucophage the day of the procedure and 48 hours post procedure. If you are having a test injection, hold your pain medication. Please take all your medications on the day of procedure other than the ones you have been informed to stop. Please call the University of Maryland Spine staff prior to your appointment if you have any questions or concerns.
A total of 34 patients met our inclusion criteria and were followed at 6 weeks, 6 months, and 12 months. Sixty-five percent of patients at 6 weeks, 62% at 6 months, and 54% at 12 months had a successful outcome, reporting at least a >50% reduction between pre-injection and post injection visual analog pain scores. Fifty nine percent of patients had an improved walking tolerance at 6 weeks (p <), 56% at 6 months (p <), and 51% at 12 months (p=). Fifty percent of patients had an improved standing tolerance at 6 weeks (p= ), 54% at 6 months (p < ), and 51% at 12 months (p=). The patient satisfaction scale revealed 64% of patients felt completely or somewhat better at 6 weeks, 59% at 6 months and 52% at 12 months. Owestry low back pain disability questionnaire scores showed statistically significant improvement from initial scores to 6 weeks (p < ), initial to 6 months (p= ), and initial to 12 months (p=). The outcome was statistically significant even in severe stenotic patients when comparing initial mean scores to 12 month mean scores in standing tolerance (p =), walking tolerance (p=), and VAS (p= ).
