OBJECTIVE To investigate the association between fetal distress (abnormal cardiotocograph tracing and/or a low fetal pH) and the levels of fetal IGFBP-1. METHODS Prospective comparative study. METHODS Twenty-two women in labour with evidence of fetal distress defined by FIGO criteria and 19 women in uncomplicated labour. The gestation range was 37 to 42 weeks and birthweight range was 2500 to 4240 g. IGFBP-1 was determined by radioimmunoassay. RESULTS The umbilical levels of IGFBP-1 were significantly higher in the study group compared with the control group (median 282.5 micrograms/l versus 128 micrograms/l, P = 0.0046; Mann-Whitney U test). There was a significant inverse correlation between fetal IGFBP-1 and cord pH (r = 0.58, P < or = 0.0001). There was no difference between the maternal serum levels of IGFBP-1 in the two groups. CONCLUSIONS Umbilical IGFBP-1 is elevated in association with fetal distress.

D005316 Fetal Distress A nonreassuring fetal status (NRFS) indicating that the FETUS is compromised (American College of Obstetricians and Gynecologists 1988). It can be identified by sub-optimal values in FETAL HEART RATE; oxygenation of FETAL BLOOD; and other parameters. Nonreassuring Fetal Status,Fetal Status, Nonreassuring
D005865 Gestational Age The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.
