Deep brain Stimulation Generator Replacement Surgeries : Safety and Efficacy of PEAK Plasmablade TMX and Analysis of Wound Healing Complications.

OBJECTIVE

This study aimed to assess the safety and efficacy of using the PEAK Plasmablade TMX (PBX) in deep brain stimulation (DBS) of implantable pulse generator (IPG) replacement surgeries, alongside identifying potential risk factors for postoperative complications.

METHODS

A prospective study was conducted on 50 patients undergoing IPG replacement with PBX, compared to 150 historical controls. Demographic data, surgical characteristics, and postoperative outcomes were analyzed. Logistic regression was used to identify predictors of surgical complications.

RESULTS

The demographic and clinical profiles of patients in the PBX group were comparable to those in the control group. PBX significantly reduced surgical duration (p=0.005) and did not result in impedance abnormalities. While wound complications did not significantly differ between groups, logistic regression identified diabetes as a significant predictor of wound dehiscence or delayed healing (p=0.012).

CONCLUSION

The findings support the safety and efficacy of PBX in DBS IPG replacement surgeries, offering advantages such as reduced surgical duration and minimized risk of impedance abnormalities. However, diabetes emerged as a significant predictor of adverse wound outcomes, highlighting the need for tailored preoperative assessment and management strategies.
