Comparison Of Effective Radiation Shielding Between Rampart IC, M1128 Shield vs Conventional Apron And Shields In Clinical Interventional Procedures (RAMPART)

July 21, 2022 updated by: Varinder Singh, Northwell Health

Comparison Of Effective Radiation Shielding Between A Portable, Configurable, Floor-Supported Radiation Protection System vs Conventional Apron And Shields In Clinical Interventional Procedures

Previous studies have documented that orthopedic injuries and musculoskeletal pain are a likely result of wearing heavy leaded aprons. This single-center, randomized 1-3 month clinical study compares conventional lead aprons and ancillary shields to the Rampart IC, M1128 radiation protection system in order to improve radiation safety with minimal orthopedic strain by using the RAMPART device. There will be three study arms, each arm requiring 21 procedures for a total of 63 total procedures, Each procedure will be randomized, instead of individual subjects. Each enrolled subject may be involved in more than one procedure/case. Randomization stratification will be 1:1:1 to either Rampart shield only, lead apron and ancillary shield, or lead apron and Rampart Shield. Real-time dosimeters will be used in each procedure to measure radiation attenuation.

Detailed Description

Previous studies have documented that orthopedic injuries and musculoskeletal pain are a likely result of wearing heavy leaded aprons that are designed to shield interventionalists and laboratory staff from radiation. A large, multicenter study found that interventional laboratory employees reported a 67% increase in the prevalence of musculoskeletal pain. Two Society of Cardiovascular Angiography and Intervention (SCAI) surveys were performed a decade apart in 2004 and 2014 which both showed similar results on the orthopedic complications on the operators who wear leaded apron protection. The surveys revealed a 60% incidence of orthopedic issues and operators who have been operating greater than 20 years in the Cath Lab compared to a 2.3% incidence of chronic spine problems in the general population. Interestingly, of the operators who had been in practice less than 5 years, 26% already had orthopedic complaints. The study also revealed that over a third of those surveyed had already had to take spine related periods of absence from the catheterization lab. Though in recent years focus on individual radiation attenuation technologies that support both attenuation and orthopedic safety have evolved, the emphasis has been on the operator. A solution has not existed to address radiation attenuation and orthopedic safety for the entire scrubbed interventional team with one system.

To address the challenge of radiation protection in this environment without the burden of wearing a heavy lead apron, Rampart IC, M1128 was created. Rampart IC, M1128 is a fully adjustable and portable system that provides radiation protection for operators and their team without having to wear a lead apron. This study will have three randomization arms, each arm requiring 21 procedures for a total of 63 total procedures. Randomization stratification will be based on procedure, not individual subject. Each enrolled subject may be involved in more than one procedure/case. Computer software will be utilized to randomize procedures in a 1:1:1 ratio to either lead apron with ancillary shield, Rampart IC, M1128, or lead apron with the Rampart IC, M1128. Real-time dosimeters will be placed on interventional staff's left temple, shoulder, and hip in order to measure radiation attenuation.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Lead Apron + Rampart IC, M1128
Consented providers will perform catherization procedures utilizing both lead apron and Rampart system. Radiation will be measured by dosimeters worn by the providers.
Device: Rampart IC, M1128 and Lead Apron
Participating providers will use both the lead apron and the Rampart Shield. Radiation exposure will be measured using real-time dosimeters.
Experimental: Rampart M1128 IC, Only
Consented providers will perform catherization procedures utilizing only the Rampart system. Radiation will be measured by dosimeters worn by the providers.
Device: Rampart IC, M1128
Rampart IC, M1128 aims to address the challenge of radiation protection in the cardiac catheterization laboratory without the burden of wearing a heavy lead apron. Rampart M1128 is a compactly designed, portable, fully adjustable system that provides radiation protection for interventionalists and their technicians. It has independently adjustable flexible panels, allowing interventionalists multiple vascular access points, including right radial, bi-lateral femoral, and bi-lateral pedal. Participants in this arm will conduct catherization procedures using only the Rampart System, and radiation exposure will be measured using real-time dosimeters.
Other Names:
  • Rampart Shield
  • Rampart
  • Rampart System
  • Rampart M1128
Active Comparator: Lead Apron Only
This is the control group. Consented providers will perform catherization procedures utilizing only the lead apron and ancillary shields (lead skirt, vest, thyroid collar (all at least 0.5mm Pb) with use of under table lead per lab operating policy and mobile suspended lead-acrylic shield and lead glasses). Radiation will be measured by dosimeters worn by the providers.
Device: Lead Apron and Ancillary Shield
Participating providers in this arm will use conventional skirt and vest, thyroid collar, and 100% use of 2 types of ancillary shields. Most wrap-around skirts and vests were (0.25-0.5 mm) Pb. Thyroid shields were 0.5 mm Pb equivalent. Under the table lead x 2. Radiation exposure will be measured using real-time dosimeters.
Other Names:
  • LAS
