Aim:

To compare serial tibial speed of sound (SOS) value

s of small

for

gestational

age (SGA) versus appropriate

for

gestational age (AGA) preterm infants.

Material and methods:

Clinical and laboratory data of preterm newborns born

at 24

35 gestation week and assessed by serial tibial SOS from postnatal week 1

were retrospectively reviewed.

Results:

A total of 67 preterm infants, of which 44 were AGA and 23 were SGA,

were includ

ed in the study. There were also serial tibial SOS measurements of

the third week of 50 of these newborns and of the sixth week of 31. The mean

birth weights of SGA and AGA groups were similar (1341±299 g and 1359±457 g,

respectively, p = 0.59); however th

e mean gestational ages of SGA group were

higher (33.8±2.6 weeks and 29.8±3.weeks, respectively, (p <0.001). The effects

of being SGA

AGA and gestation week on tibial SOS values were calculated by

univariate analysis. The tibial SOS values in the SGA and

AGA groups were found

to be the first week of (3051 ± 169 m/s and 2915 ± 116 m/s, respectively, p =

0.09), the third week of ( 3017 ± 180 m/s and 2906 ± 124 m/s, respectively, p =

0.57) and the sixth week of (2977 ± 152 m/s and 2882 ± 103 m/s, respectively

, p

= 0.38).

Conclusion:

Tibial SOS values at postnatal first, third and sixth week were similar

in AGA and SGA preterm newborns. In order to obtain a clear conclusion about

this issue, there is a need for prospective studies in which the number of samples

is appropriate and serial tibial SOS measurements were compared between

preterm SGA and AGA neonates matched in terms of prenatal risk factors.
