Efficacy of median nerve hydrodissection by hyalase versus midazolam in the treatment of carpal tunnel syndrome.

Background

The objective was to determine which of midazolam or hyalase could improve the pain score and functional disability in median nerve hydrodissection.

Methods

In a double-blind study with two groups, both received bupivacaine 15 mg with either 300 IU hyalase in 2 ml of saline (group HA) or 2 mg of midazolam in 2 ml of sterile saline (group MZ).

Results

Statistically significantly lower post-injection Visual Analog Scale scores in group MZ compared with group HA at all follow-ups. Group MZ had significantly lower functional disability scores than group HA.

Conclusion

Both drugs yielded favorable results. Midazolam was more impactful in alleviating pain and reducing functional disability up to 6 months.
