Irradiance of phototherapy equipment in maternity wards in Maceió

High variability and low irradiance of phototherapy devices in Dutch NICUs

“…However, we found that it does not. In fact, our results are not that different from those in developing countries 7–9. Pejaver and Vishwanath studied PT devices among 24 Indian neonatal care centres.…”

“…Adherence to this recommendation has not been investigated thoroughly. Only a few studies from developing countries measured low irradiance suggesting that PT is not always applied effectively 7–9. Limited resources with inferior light sources, maintenance constraints, inconsistent power supply and lack of awareness of healthcare workers are probably the most important barriers to effective PT 10.…”

Evaluating the efficacy of phototherapy devices

“…The time also appears to be ripe for the replacement of ineffective, defective, and worn-out devices that deliver inadequate therapy, as has been demonstrated through recent surveys in India, Nigeria, and Brazil [1][2][3]. Because of a rapidly expanding global market for PT devices, the medical device industry, particularly in India, appears to be actively engaged in the production of newer and, undoubtedly, more effective and affordable LEDbased devices.…”

Conhecimento, atitude e prática sobre fototerapia entre profissionais de enfermagem de hospitais de ensino

“…Apesar da eficácia da fototerapia ser avaliada pelo comprimento da luz, irradiância espectral e superfície corpórea exposta a luz (2,19) , identificou-se que alguns profissionais do ní-vel médio não citaram a irradiância e o espectro da luz como fatores que interferem na eficácia desta terapêutica, assim como outros aspectos, tais como, foco luminoso e a distância para o recém-nascido e a área corporal exposta.…”

“…Aqui, é importante ressaltar que quanto maior a superfície exposta à luz, maior a eficácia da fototerapia (9,19) . Ainda em relação ao posicionamento do recém-nascido, o manual do fabricante orienta que deve ser posicionado de forma que a radiação incida em todo o seu corpo, para que haja o aproveitamento do foco luminoso na fototerapia convencional.…”
