Thoracic medial branch block, Southlake
Objective
Chronic neck or back pain, Southlake can be managed with
various procedures. Although these
procedures are usually well-tolerated, a variety of side effects have been
reported. In this study we reviewed cases of unexpected temporary adverse
events after blocks and suggest possible causes.
Methods
We reviewed the records of patients treated with spinal pain
blocks between December 2009 and January 2011. The types of blocks performed
were medial branch blocks, Southlake interlaminar
epidural blocks and transforaminal epidural blocks.
Results
There were 704 procedures in 613 patients. Ten patients had 12 transient neurologic events. Nine patients were in Group A and one
was in Group B. Transient complications occurred in four patients after
cervical block and in eight patients after lumbar block.
Side effects of lumbar spine blocks were associated with the
concentration of mepivacaine (p<0.05.
Conclusion
Spinal pain blocks are a good option for relieving pain, but clinicians should always keep in mind the potential for
development of inevitable complications.
Careful history-taking, appropriate selection of the anesthetics,
and using real-time fluoroscopy could help reduce the occurrence of adverse
events.
