RESUMO
ABSTRACT Purpose: Evaluate the patients in two neonatal intensive care units in Paraná/Brazil and identify the risk factors for the development of retinopathy of prematurity. Methods: We performed a prospective cohort study on premature infants with gestational age ≤32 wk and/or with birth weight ≤1500 g who were admitted to the neonatal intensive care unit of Hospital do Trabalhador and Hospital Infantil Waldemar Monastier. These hospitals admit patients referred from other maternity hospitals in the state of Paraná. The study duration was 12 mon. Results: The incidence of retinopathy of prematurity was higher in the Hospital Infantil Waldemar Monastier than in the Hospital do Trabalhador for premature infants who needed to be transported from their birthplace to the intensive care unit (52.2% vs. 29.6%). The following risk factors were associated with the development of the disease: longer hospitalization, low gestational age at birth, longer oxygen use, vasoactive drugs use, no antenatal corticosteroids use, intracranial hemorrhage, and any glycemic disorder. Low birth weight was an independent risk factor for the development of retinopathy of prematurity. Conclusion: Early neonatal care and transportation of premature infants may influence the occurrence and prognosis of retinopathy of prematurity.
RESUMO Objetivos: Avaliar duas unidades de terapia intensiva neonatais do Paraná e identificar os fatores de risco que levam ao desenvolvimento da retinopatia da prematuridade nestas unidades neonatais. Metodos: Foi realizado um estudo de coorte, prospectivo, com avaliação dos bebês prematuros examinados no período de 12 meses com idade gestacional ≤32 semanas e/ou com peso de nascimento ≤1500 gramas, internados na unidade de cuidados intensivos neonatais do Hospital do Trabalhador e do Hospital infantil Waldemar Monastier, que recebe neonatos transportados das maternidades de todo o estado do Paraná. Resultados: A incidência de retinopatia da prematuridade foi maior no Hospital Infantil Waldemar Monastier, entre os prematuros que necessitaram de transporte do local de nascimento para a unidade de cuidados intensivos (52,2% vs 29,6%), Os fatores de risco associados ao desenvolvimento da doença foram; Maior número de dias de internamento, baixa idade gestacional ao nascimento, maior tempo de uso de oxigênio, uso de drogas vasoativas, ausência de uso de corticoide pré-natal, presença de hemorragia intracraniana e qualquer tipo de alteração da glicemia. Conclusão: Os cuidados neonatais precoces e o transporte do recém-nascido pré- termo podem influenciar a ocorrência e o prognostico da retinopatia da prematuridade.
