A restraint and transillumination device for neonatal arterial/venipuncture: efficacy and thermal safety

A different method of restraint together with technical details for construction demonstrating the use of reflected high intensity fiberoptic light is presented. Thermal data are presented demonstrating safety within recognized biologic skin temperature safety which permits utilization of a high intensity See Images in the PDF File light source for arterial or venous cannulation for prolonged periods of time extending to 20 minutes. This device presents a method to demonstrate visualization of blood vessels in the infant's extremity without risk of thermal burn associated with an adequate flexible restraint quick-release mechanism. Disposable polyurethane 5-mm pads (cut from sheets) were utilized to minimize pressure on bony prominences or nerves of the extremity. Neither thermal burns nor pressure alterations have been noted. Although not specifically evaluated, the use of a heat filter and CS-2-73 orange filter might further reduce heat buildup while using this device.
