Background patterns and sleep-wake cycles on amplitude-integrated electroencephalography in preterm infants with periventricular-intraventricular hemorrhage / 中国当代儿科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the background patterns and sleep-wake cycles (SWC) on amplitude-integrated electroencephalography (aEEG) in preterm infants with different grades of periventricular-intraventricular hemorrhage (PIVH).</p><p><b>METHODS</b>Fifty-six preterm infants with a gestational age between 25 and 33 weeks who were diagnosed with PIVH and 31 gestational age-matched normal preterm without ICH were enrolled. According to Papile staging criteria, the infants with PIVH were subdivided into mild group (grades I and II) and moderate-severe group (grades III and IV). The results of the aEEG were compared between groups.</p><p><b>RESULTS</b>The moderate-severe PIVH group showed a decreased continuity of the voltage, an increased loss rate of SWC, and a lower aEEG score than the mild PIVH and control groups (P<0.017). There were no significant differences in these parameters between the mild PIVH and control groups.</p><p><b>CONCLUSIONS</b>The changes of background patterns and SWCs may be associated with the severity of PIVH in preterm infants.</p>
