“…20 (1992) Brought to you by | Michigan State University Authenticated Download Date | 7/1/15 1:53 AM newborns, the auditory brainstem conduction time was apparently unaffected by IUGR [4]. In contrast in another study, the brainstem conduction time was found to be increased in a population of SGA fullterm infant [17]. All these findings confirm that SGA infants represent a heterogeneous population and that the numerous causes of IUGR may have different consequences of cerebral development.…”

“…The growth retardation frequently observed in twins after 35 weeks of gestation is probably responsible for this abnormal brainstem function: after this time the utero-placental function becomes inadequate to meet nutritional needs of more than one fetus [9]. Such utero-placental impairments could explain the delayed auditory brainstem conduction time observed in a study of some SGA fullterm infants [17]. Later, in early infancy, increased BAERs interpeak-latencies have also been reported in severely malnourished children with kwashiorkor or marasmus [2,3].…”

Brainstem auditory evoked responses (BAER) were recorded in 89 neonates born between 32 and 40 weeks, in order to analyze the consequences of intrauterine growth retardation on brainstem conduction time. The I-V interval was measured in 28 appropriate for gestational age (AGA) infants (control group), in 24 small for gestational age (SGA) infants with maternal hypertensive disease (MHD) and in 37 SGA infants without MHD. At any gestational age, SGA infants with MHD always presented an acceleration of their brainstem conduction time as compared to the other SGA infants. For the SGA full-term twins without MHD, the brainstem conduction time was delayed. These results reflect the specific consequences on brainstem development of the various factors responsible for intrauterine growth retardation (IURG).

“…There are a few authors who reported their BAER studies in SGA infants or children born at various gestations. Some of them found abnormalities (e.g., increase or shortening in wave latencies and interpeak intervals, although the others did not [14][15][16][17][18][19][20][21][22]). So far, there is no consensus with regard to the effect of SGA or IUGR on brainstem auditory function in infants.…”

Saintonge et al [22] reported that peak latencies of waves III and V in small for date human neonates in creased compared with the healthy neonates, and speculated that the difference was due to fetal malnutrition.…”

The effect of early postnatal undernutrition on the development of brainstem auditory evoked potentials (BAEPs) was examined using rats during the weanling period. Undernutrition was achieved by separating the suckling rats from the mother for 24 h every other day from 1 day through 10 days of age (group 1) or from 1 day through 14 days of age (group 2). Both groups were rehabilitated nutritionally after these periods. The littermates which were not separated from the mother were used as well-fed control. At 14 days of age, wave IV of BAEPs was detected in 44% of group 1 and in 69% of group 2, where it was detected in all control rats. Peak latency of wave IV and I-IV interpeak latency (IPL) of group 2 rats were significantly longer than those in control rats from 14 through 22 days of age. Similarly, those of group 1 rats were significantly longer than those in control rats at 14 and 18 days of age. At 33 days of age, there were no significant differences in terms of peak latencies (waves I, III and IV) and IPLs (I–III and I–IV) between both the undernourished groups and the control group. These results indicate that early postnatal undernutrition delays the development of BAEPs in rats transiently, and nutritional rehabilitation can make the group Ê»catch up’ on BAEPs.
