MethodsCross-sectional study of infants with gestational age <32 weeks. Intra-ventricular hemorrhage was identified by cranial ultrasonography and classified according to Papile et al. (1978). The luminous (flashlight), sound (rattle, bell), and tactile stimuli were presented, and the responses were scored according to Lester and Tronik (2004). Habituation response scores were compared between groups by Student's t-test. The association between IVH and habituation scores was evaluated by linear regression adjusted for GA, clinical severity score, post-conceptual age at habituation assessment, sepsis, and bronchopulmonary dysplasia. ResultsSixty-five infants were studied, 20 with intra-ventricular hemorrhage (16 grades I/II; four grades III/IV) and 45 without intra-ventricular hemorrhage. Infants with intra-ventricular hemorrhage had lower gestational age (28.2±2.2 vs. 29.7±1.7 weeks) and birth weight (990±305 vs. 1275±360g). Infants with intra-ventricular hemorrhage at 36–38 weeks post-conceptual age had lower habituation scores to light (4.21±2.23 vs. 6.09±2.44), rattle (3.84±2.12 vs. 6.18±2.27), and bell (3.58±1.74 vs. 5.20±2.47) after controlling for confounders. No differences were found for tactile stimulus. ConclusionInfants with gestational age <32 weeks and intra-ventricular hemorrhage had poorer habituation responses to external stimuli than those without intra-ventricular hemorrhage at 36–38 weeks post-conceptual age.
