Effectiveness, Safety and Perceptions With the Use of One LED Blanket Device in the Ambulatory Treatment of Jaundice

Summary

Objective: to evaluate the effectiveness, safety and level of satisfaction of parents and healthcare team with one innovative device for phototherapy to which a LED light mesh has been incorporated(a blanket), comparing it with the Ohmeda BiliBlanket Plus®. Methods: randomized controlled clinical trial with preterm or low birth weight infants requiring phototherapy. The study protocol was evaluated and accepted by the San Ignacio Hospital and "Pontificia Universidad Javeriana" research committee. Informed consent was requested from parents and the authors declared no conflict of interest. Sample size and allocation: using the STATA 12 program, a sample size of 64 patients was calculated(5% losses), 32 for each group, with significance level of 0.05, power of 80% and difference in bilirubin decreasing of at least 0,1 mg/dl/h with standard deviation of 0.14 mg/dl/h. A computer program randomized the allocation to the intervention and the concealment of the assignment was through sealed opaque envelopes. Seric bilirubin levels were taken at the start and at the end of phototherapy. Controls were done every 2 hours with the Bilicheck spectrophotometer device. Axillary temperature was measured at the beginning of phototherapy, at 30 min, 60 min, and every 2 hours during intervention. Physical examination and recording of side effects related were performed. Parents and health personnel answered a survey on comfort and perceptions with the use of the devices at the end of phototherapy. Analysis: Comparison of means was made for the decrease of bilirubin levels and body temperatures and chi-square for incidence of side effects and results of the survey.

Interventions

DEVICE

Neomedlight Phototherapy Blanket

The NeoMedLight® phototherapy blanket is an innovative new fiber-optic device based on LED light. Its light emitting surface area is 40.5x30 cm or 1200 cm2. The device size is 40.5 x30 cm. It incorporates fiber optic mesh and is protected by a vinyl cover and a disposable liner for patient comfort and hygiene. This device provides therapeutic light (404-515nm) to a wide extension of the body surface area. Its average irradiation footprint is 35uW / cm2 / nm ± 15%. The phototherapy was done intermittently in periods of 2 hours with 1 hour of rest for a total time of 6 hours in kangaroo position.

DEVICE

Ohmeda-Fiber Optic Phototherapy Blanket

This device is a high performance version of Ohmeda Medical's Biliblanket that uses a fiber optic cable to deliver light from a high-intensity lamp to a device composed of a fiber optic fabric. The device has a disposable liner and is left in direct contact with the patient. The patient is exposed to a light with a wavelength between 400 and 550 nanometers. The phototherapy system consists of a light emitting unit, a fiber optic cable four feet long (121.9 cm) and a lightweight mattress. It has two available sizes: 4.38 x 9.38 inches (11.12 x 23.83 cm) and 4.00 x 6.00 inches (10.16 x 15.2 cm).
