PURPOSE
To investigate the relationship between voiding pattern and brain activity by using Video- electroencephalogram (EEG)
in healthy preterm newborn.
MATERIAL AND METHODS
Forty-seven healthy preterm neonates (16 female) whose conceptual age (CA) was 34.10±1.81 weeks: group
Ⅰ
(31
weeks
≦
CA < 33 weeks; n=13), group
Ⅱ
(33 weeks
≦
CA < 35 weeks; n=14) and group
Ⅲ
(35 weeks
≦
CA < 37 weeks;
n=20). Video-EEG data from eight cortical regions were recorded from 8a.m. to 12a.m.. Meanwhile, the 4h free voiding
parameters including voiding frequency (VF), voiding volume (VV), post-voiding residual volume (PRV) and status at
voiding (awake/sleep) were recorded.
RESULTS
There was no significant difference in VF and VV/BW between the three groups (P > 0.05). VF in sleeping preterm
neonates of group
Ⅲ
was significantly less than that of the other two groups (P
﹤
0.05). PRV/BW of group
Ⅰ
was
significantly larger than that of group
Ⅱ
and group
Ⅲ
. The electrode pair Fp1-T3 and Fp2-T4 amplitude showed
significant difference between group
Ⅰ
and group
Ⅱ
, the electrode pair C3-O1 and C4-O2 amplitude showed significant
difference in group
Ⅲ
during quite sleep voiding(QSV), 5 second before and after voiding (P
﹤
0.05). Comparing the
amplitude in the three groups during QSV, 5 second before and after voiding, the electrode pair Fp1-T3, C3-O1 and T3-
O1 respectively showed significant difference during 5 second before voiding, QSV and 5 second after voiding (P
﹤
0.05).The EEG frequency showed no significant difference in the three groups during QSV, 5 second before and after
voiding (P > 0.05).
CONCLUSIONS
Even in the early preterm neonate, the brain maybe has played a role in control of voiding function in QSV. With the age
increasing, the central region and occipital area of the brain, especially the left cerebral regions in preterm neonates
played an important part in voiding control.
