RESUMEN
OBJECTIVE: To describe the outcome for 92 fetuses treated between May 1987 and January of 1993 with intrauterine (intravascular) transfusions for severe hemolytic disease in comparison with a high-risk and a healthy control group. STUDY DESIGN: Information on the perinatal period was obtained from the patient records. The children regularly attended the outpatient clinic, and a general pediatric examination was performed on each visit. The psychometer development of the child until age 4 1/2 years was assessed according to Gesell. At the age of 5 years, the adaptation part of the Denver Developmental Screening Test and a Dutch-language test were used. A neurologic examination was performed according to Touwen. RESULTS: In our study, 77 (83.7%) of 92 fetuses were born alive after intravascular transfusions. The overall survival rate was 79.3%. The follow-up group included 69 infants, with an age range of 6 months to 6 years. Correlation between antenatal and perinatal features showed a significant negative relationship between the number of intrauterine transfusions and the duration of phototherapy (p = 0.002). The probability that neurologic abnormalities would occur was significantly greater when perinatal asphyxia had been present (p < 0.05) and with a lower cord hemoglobin level at birth (p = 0.03). The total number of children with disabilities was 10.1% (7/69). CONCLUSIONS: The neurodevelopmental outcome for the group of survivors compared favorably with a group of high-risk, very low birth weight infants (10.1% to 18%), and less favorably with a healthy control group (10.1% to 6%).
