RESUMO
OBJECTIVE: To identify the relationship between prophylactic indomethacin (PI) administration and incidence of intraventricular hemorrhage. STUDY DESIGN: A retrospective analysis of extremely premature infants <27 weeks gestational age born between January 2014 and September 2020. RESULTS: A total of 421 infants were included from three of Nationwide Children's Hospital delivery centers. Of those 255 (61%) received PI. After adjustment by inverse proportionality treatment weighting (IPTW), no differences were found in incidence of intraventricular hemorrhage (IVH) at the time of the first ultrasound, 31% vs. 33% in PI and control groups respectively (p = 0.68). The rate of rise of serum creatinine from baseline to day of life four was significantly higher in the PI group (0.14 mg/dl PI and 0.03 mg/dl control, p < 0.001). CONCLUSION: PI was not associated with any benefit in prevention of IVH, but is associated with adverse effects including acute rise in creatinine.
