Abstract:
Objective To investigate the clinical value of the bedside color Doppler in the assessment infants with periventricular-intraventricular hemorrhages (PIVH).Methods Sixty-eight cases of PIVH newborns and 156 healthy newborns were involved in the study,dynamic monitoring were undergone within a week after birth.The middle cerebral artery(MCA) hemodynamic parameters of velocity systolic (Vs),velocity diastolic(Vd) and resistance index (RI) were recorded,and the differences of the parameters were compared between different grades as well as those of the normal newborns at 1 d,4 d and 7 d after born.Results Total 68 PIVH infants were diagnosed by bedside color Doppler accurately.Prevalences of premature and low birth weight infants were higher than term infants and normal birth weight children,respectively (P ＜0.05).Vs and Vd of 4 groups of children with PIVH showed an increasing trend in a week after born.The differences of Vs between grade Ⅰ and normal newborns in 4 d and 7 d were not statistically significant (P＞ 0.05),the differences of the other three groups compared with normal newborn group in1 d,4 d and 7 d were statistically significant (P ＜0.05).Vd of grade Ⅱ newborns within 7 d were greater than those of other 4 groups (P ＜0.05),grade Ⅲ and grade Ⅳ within 7 d were less than healthy newborns (P ＜0.05).The difference of RI between all groups were not statistically significant (P ＞ 0.05).Conclusions The diagnostic accuracy rate of PIVH by bedside Doppler is high and the dynamic monitoring of neonatal hemodynamics could provide an important basis for assessing the occurrence and development of PIVH.
