[Examination of cerebral electrical admittance plethysmogram in healthy newborns].

Abstract

OBJECTIVE Cerebral electrical admittance plethysmography is a novel noninvasive technique for evaluating cerebral hemodynamics. This study aimed to measure the reference values of cerebral electrical admittance plethysmogram in healthy newborns. METHODS Bilateral cerebral electrical admittance plethysmography was performed in 40 healthy newborns. RESULTS The values of various indexes of cerebral electrical admittance plethysmogram in 40 newborns were obtained by this technique. The index of Admittance Differential Loop (ADL) I+II at the third and fourth days after birth was significantly higher than that at the first day of life (P < 0.05). There were significant differences in the index of ADL I+II and the ratio of Hs to b-S (Hs/ b-S) among different birth weight groups (P < 0.05). No significant differences were found in all the indexes of cerebral electrical admittance plethysmogram between the left and right brain of newborns. Gender and parturition mode had also no effects on these indexes. CONCLUSIONS The research reported the reference values of cerebral electrical admittance plethysmogram in healthy newborns. The postnatal age and birth weight are influencing factors for the cerebral electrical admittance plethysmogram.
