Study Design:
This is a report of three cases of epidural abscess occurring after use of intraoperative epidural methylprednisolone in 31 patients who had undergone lumbar microdiscectomy. The possible role of epidural steroids in the cause of these abscesses is discussed, and a review the literature concerning its value is provided.
Objective:
To evaluate experiences with the efficacy and safety of perioperative methylprednisolone.
Summary Of Background Data:
No previous study has described a high infection rate with the use of epidural methylprednisolone. The literature supporting epidural steroids is equivocal, and reports supporting their perioperative use are scant.
Methods:
In an 8-month period, 31 patients received 1 mL (40 mg) epidural methylprednisolone at the conclusion of microdiscectomy. Therapy was discontinued after an increased postoperative deep infection rate was noted. Results in these patients were compared with those in more than 400 others who did not receive intraoperative steroids during a 7-year period.
Results:
In the steroid group, three epidural abscesses were encountered. There were no deep infections in the nonsteroid group.
Conclusion:
The use of perioperative epidural methylprednisolone in the currently reported cases was associated with three incidences of infection. A prospective study is needed to examine its use.
Insights
Perioperative epidural methylprednisolone use after lumbar microdiscectomy was linked to three cases of epidural abscess in a small patient group. Further research is needed to confirm this association and assess steroid safety.
Area of Science:
- Neurosurgery
- Anesthesiology
- Infectious Disease
Background:
- Limited evidence supports perioperative epidural steroid efficacy.
- Previous studies have not reported a high infection rate with epidural methylprednisolone.
Observation:
- Thirty-one patients received epidural methylprednisolone post-lumbar microdiscectomy.
- An increased rate of deep postoperative infections was observed.
- Therapy was discontinued due to observed infections.
Findings:
- Three cases of epidural abscess occurred in the group receiving epidural methylprednisolone.
- No deep infections were reported in over 400 patients who did not receive intraoperative steroids.
Implications:
- Perioperative epidural methylprednisolone may be associated with an increased risk of epidural abscess.
- A prospective study is warranted to investigate the safety and efficacy of perioperative epidural steroids.
- Findings suggest caution in the use of epidural steroids following lumbar microdiscectomy.
