ABSTRACT

Devido às suas ações anti-inflamatórias, os corticosteróides têm sido utilizados para prevenção de displasia broncopulmonar, sendo descrita, uma redução da incidência desta patologia. No entanto, efeitos adversos a curto e a longo prazo têm sido detectados, em recém-nascidos pré-termo. OBJETIVO: Analisar os efeitos sobre a incidência de displasia broncopulmonar, duração de ventilação mecânica e de internação, mortalidade, crescimento, além dos efeitos adversos dos corticosteróides, administrados entre 10-14 dias de vida, em recém-nascidos de muito baixo peso, dependentes de ventilação mecânica. MÉTODOS: Realizou-se estudo de coorte, incluindo-se todos os recém-nascidos com peso de nascimento < 1500 gramas dependentes de ventilação mecânica, entre 10-14 dias de vida. Foram divididos em: Grupo I - receberam dexametasona (16) e Grupo II - não receberam dexametasona (22). Administrou-se dexametasona, a partir do 10º dia de vida, dias 1 a 3 - 0,3 mg/kg/d, dias 4 a 6 - 0,2 mg/kg/d, dias 7 a 9 - 0,1 mg/kg/d. Analisou-se o desenvolvimento de displasia broncopulmonar (dependência de oxigênio aos 28 dias de vida), efeitos sobre a evolução respiratória e sobre o padrão de crescimento, além da ocorrência de efeitos adversos. RESULTADOS: A incidência de displasia broncopulmonar não diferiu entre os grupos (GI - 62,5%; GII - 22,7%;p = 0,07). Detectou-se desaceleração do crescimento no GI em relação ao GII(D P = 47g/semana, GI e 85,5g/semana, GII; p = 0,06; D PC - 0,75 cm/semana GI e 1cm/semana, no GII; p = 0,05). CONCLUSAO: O uso de corticosteróides, em recém-nascidos pré-termo, entre 10 - 14 dias de vida não reduziu incidência de displasia broncopulmonar e causou uma desaceleração do crescimento.

ABSTRACT

Ventilator-dependent premature infants are often treated with dexamethasone. Several trials showed that steroids while improve pulmonary compliance and facilitate extubation, some treated infants may have adverse effects, such as alterations of growth curves. We conducted this retrospective study to evaluate the effects of steroids on mechanical ventilation, oxygen therapy, hospital length stay and mortality, in ventilator-dependent infants with bronchopulmonary dysplasia (BPD) (defined as the need of oxygen supplementation at 28 days of life). Twenty-six newborns with BPD were evaluated during 9 3/4 42 days postpartum (mean = 31 days) and were divided into two groups: Group I - 14 newborns that did not receive dexamethasone, and Group II - 12 newborns that received dexamethasone at 14 3/421 days of life. Dexamethasone was given at a dose of 0.25 mg per kilogram of body weight twice daily intravenously for 3 days, after which the dose was tapered. RESULTS: There were no statistically significant differences in the mean length of mechanical ventilation (Group I - 37 days, Group II - 35 days); oxygen supplementation (Group I - 16 days, Group II - 29 days); hospital stay (Group I - 72 days, Group II - 113 days); mortality (Group I - 35.7 percent, Group II - 41.6 percent). At birth, Group II was lighter (BW: Group I - 1154 grams +/- 302, Group II - 791 grams +/- 165; p<0.05) and smaller (height: Group I - 37.22 cm +/- 3.3, Group II - 33.5 +/- 2.4; <0.05) than Group I. At 40 weeks, there were no statistically significant differences between groups in relation to anthropometric measurements. CONCLUSIONS: The use of corticosteroids in bronchopulmonary dysplasic infants may influence the somatic growth during its use. However, after its suspension, a recovery seems to occur, suggesting that its influence could be transitory.
