简要总结
The purpose of this study is to gather information comparing LessRay Enhanced fluoroscopy with the current standard of fluoroscopy. This research is being conducted to demonstrate the utility and effectiveness of LessRay Enhanced fluoroscopy during surgical placement of a spinal cord stimulator epidural array.
详细描述
The purpose of this prospective, randomized single center study is to assess the ability of LessRay to decrease overall radiation exposure during surgical placement of a spinal stimulator. A secondary objective is to analyze the efficacy of utilizing enhanced low radiation imaging in a fluoroscopically intensive pain procedure.
The population group will be 65 patients from Duke University Medical Center and Duke Raleigh Hospital who meet the medical criteria for the surgical placement of a spinal cord stimulator epidural array. They will be divided equally into 2 arms: Research and Control and randomized by a non-surgeon on the study team. That information will be recorded and placed in a sealed envelope. On the day of surgery the envelope will be delivered to the OR and opened following "time-out". At the time the envelope is opened in the OR the patient is acknowledged to be evaluable for failure or success of LessRay during the surgical procedure if they are in the research arm. The control arm cohort will proceed with the surgery as typical without LessRay.
The data from the two groups (Research vs. Control) will be analyzed using a two tailed t-test with p<.05. The risks associated specifically with the implementation of this study are with respect to loss of confidentiality. Every effort will be made to keep the information confidential

入选标准
- •Male or female adults of any ethnicity
- •At least 18 years-old but without an upper age limit
- •Subject is willing to provide informed, written consent to participate in this study
- •Subject meets the medical criteria for surgical placement of a spinal cord stimulator epidural array (e.g. not pregnant)
排除标准
- •Less than 18 years of age. For both physicians involved in the study, standard of care Spinal Cord Stimulator placement is not done for those patients under 18 years of age as the literature does not show that the procedure helps in back pain of this cohort of patients
- •Unable to provide informed, written consent
- •Pregnant women as pregnancy makes them ineligible to undergo a surgical placement of a spinal cord stimulator
- •Prior placement of a spinal cord stimulator epidural array or previous thoracic spine surgery, which could potentially make placement more difficult
- •Enrollment in another study, which would prohibit participation in this study
