What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new device designed to maintain proper patient positioning during brain surgeries that use intraoperative MRI. Researchers aim to determine if this new prone positioning device (Prototype Prone Positioning Device) is safe and as effective as the standard pads currently in use. The trial seeks adult patients with epilepsy undergoing a specific type of surgery at the University of Kansas Medical Center. Participants must be able to provide informed consent and meet the device's weight limit. As an unphased trial, this study offers patients the chance to contribute to innovative research that could enhance surgical outcomes.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators or your doctor.

What prior data suggests that this prone positioning device is safe for neurosurgery?

Research has shown that using intraoperative MRI (iMRI) during surgeries can enhance safety by improving surgical precision. This technology brings the MRI machine directly to the patient, providing doctors with clearer images during operations. However, iMRI presents some safety concerns. For example, certain implants like pacemakers and metal joints can pose issues in an MRI environment.

Regarding the new device being tested, which aids in positioning patients face-down during surgery, specific safety information is not yet available. As this trial is in its early stages, the primary goal is to assess the device's practicality for use in surgeries with iMRI. Detailed safety results are pending. Therefore, the study will closely monitor any problems or complications that arise when using this new device compared to the usual positioning pads. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the prototype prone positioning device for neurosurgery because it offers a new way to improve precision during complex procedures. Unlike traditional methods that might limit imaging capabilities, this device is designed to be used with intraoperative MRI, allowing surgeons to have real-time, high-quality imaging throughout the operation. This could potentially lead to more accurate surgeries and better outcomes for patients, as the device helps maintain optimal positioning and visibility during critical procedures.

What evidence suggests that this prone positioning device is effective for neurosurgery?

Research has shown that the Prototype Prone Positioning Device is being tested in this trial to maintain patient positioning during brain surgery using MRI scans. This device holds the patient steady with an accuracy of 0.8 to 1.7 millimeters. Such precision is crucial for surgeries requiring exact imaging, like brain operations. The device provides a stable and adjustable platform, potentially reducing risks compared to traditional pads. Although this method is new, early indications suggest it could enhance surgery outcomes by improving imaging accuracy during the procedure. ^{1 3 6 7 8}

Published Research Related to This Trial

In a 10-week study involving 164 patients undergoing elective orthopedic procedures, independent clinical reviewers identified significantly more adverse events (99) compared to surgeons (14), highlighting a gap in surgeons' reporting practices.

While surgeons effectively captured major adverse events, they missed many minor events that were documented by reviewers, suggesting that using standardized assessment tools like SAVES V2 and OrthoSAVES could enhance overall adverse-event reporting in clinical settings.

Can Surgeons Adequately Capture Adverse Events Using the Spinal Adverse Events Severity System (SAVES) and OrthoSAVES? Chen, BP., Garland, K., Roffey, DM., et al.[2018]

In the first 18 months after FDA approval of the Charité artificial disc, the reported rate of adverse events was relatively low, starting at 0.58% and peaking at 2.34%, indicating a manageable safety profile for this lumbar arthroplasty device.

The most common adverse event was anterior migration requiring reoperation (0.65%), but overall rates of adverse events were lower than those reported in the initial investigational studies, suggesting that the device's real-world performance may be better than initially anticipated.
