Safety in the use of dexmedetomidine (precedex) for deep brain stimulation surgery: our experience in 23 randomized patients.

OBJECTIVE

Evaluation of safety and efficacy of dexmedetomidine in deep brain stimulation (DBS) surgery.

MATERIALS AND

METHODS

A cohort of 23 patients, candidates for DBS for Parkinson's disease, Tourette syndrome, or obsessive-compulsive disorder, was randomized in two groups: dexmedetomidine group and control group. Standard anesthesiologic parameters were recorded and analyzed, together with the need for other medications. A ten-degree scale (visual analog scale) assessing patient discomfort during DBS also was recorded at the end of surgery.

RESULTS

The results demonstrated good stability of intraoperative monitoring: no respiratory depression and good overall cooperation with the neurologist, while no side-effects were recorded.

CONCLUSIONS

Our conclusion is that dexmedetomidine should be considered as a valuable option for sedation in poorly collaborating patients undergoing DBS surgery.
