Intrauterine growth retardation - perinatal mortality and morbidity in a perinatal centre

Obiectives: The intrauterine growth retardation (IUGR) contributes specially to perinatal mortality and morbidity. An effective treatment is not yet available. The purpose of this study is to analyse the perinatal data of a cohort with IUGR-infants including mortality and morbidity and to describe prematurity and IUGR as a combination of high risk. Study design: We have analysed the perinatal data of a cohort of 220 patients with IUGR-infants including mortality and morbidity. Regularly we examined fetal ultrasonographic growth, doppler measurements of fetal and maternal vessels and CTC, as well as indicated amniocentesis, placentesis and cordocentesis. Entry criteria were: normal menstrual period before pregnancy, clear gestational age, complete history of pregnancy. Results: At the Department of Gynaecology & Obstetrics, University Hospital, Homburg/Saar, the incidence of IUGR (<10th percentile) in premature babies and newborns was 13.1% over five years (1993-1997). The percentage of premature babies with IUGR was 18.6%. The overall mortality was 4.1%, the perinatal mortality was 3.6% and the neonatal mortality was 2.7%. In 1.4% intrauterine foetal death was observed, all associated with a birthweight below the 3th percentile. The average duration of pregnancy was 34+4 weeks. A high perinatal mortality of 13.1% and an overall mortality of 14.7% was observed. 11.4% of the premature babies with IUGR showed deformities and about 2% presented chromosome aberrations. 46.4% of children have been transferred to the Neonatal Intensive Care Unit. 57.1% of the postnatal complications have been related to the lungs, 26.5% to the cardiovascular system and 14.3% to the cerebrum. Maternal complications were referred to: SIH/EPH-gestosis (65.4%), HELLP-syndrome (5.8%), nicotine abuse (31.4%), pregnancy anaemia (17.3%) and gestational diabetes with insuline therapy (7.7%). On the placental site the most noticeable conditions have been placental insufficiency (40.6%) and placental infarction (28.7%). Conclusion: Children with IUGR are exposed to high perinatal mortality and postnatal morbidity. Premature babies in association with an IUGR are at high risk. The surveillance of the pregnant women and the new-born children should be performed in a perinatal centre.
