Clinical study of Abruptio placenta / 대한산부인과학회잡지

OBJECTIVE: To evaluate for the clinical analysis on abruptio placenta, we examined its incidence, diagnostic methods, symptom and sign, perinatal mortality, and recurrence rate. METHODS: We reviewed the medical records of the 396 cases of abruptio placenta among 72.580 deliveries, from Jan. 1, 1990 to Dec. 31, 1997, at St. Mary, Kang Nam St. Mary, and Holy Family Hospital of Catholic University. RESULTS: The total incidence of abruptio placenta was 0.51%, the incidence plotted by age from 1993 to 1997 has shown that the age incidence was higher in 20-24years old(0.7%), and over 35years old (0.8%). 42.5% of the case occurred between 32 to 37weeks of gestational age, 39.6% was over 37weeks. 38% of the patient was diagnosed before delivery with ultrasonography and the most common complaint was vaginal bleeding. The complication of abruptio placenta is as follows, Couvelaire uterus occurred in 26cases(7.0 %), DIC in 10cases(2.7 %), ARF in 4cases (1.1 %), and uterine rupture in 1case(0.3 %). Perinatal mortality including 41cases of stillbirth was 19.9 %(73cases) but no maternal death was noted. A history of abruptio placenta increased risk of a similar incident in a subsequent pregnancy by 19 cases(4.6 %: 9.0 fold)complicated with 13 cases of pregnancy induced hypertension(76.5 %). CONCLUSION: The incidence of abruptio placenta plotted by age have shown higher in 20-25years old and over 35 years old, hypertensive women experienced abruptio placenta are more likely to have higher graded recurrent rate in subsequent pregnancy, and abruptio placenta is major obstetric bleeding disease causing serious maternal and fetal complication.

Cord Blood Erythropoietin Complicated By High Risk Pregnancies / 대한산부인과학회잡지

OBJECTIVE: To investigate the relationship between umbilical plasma erythropoietin(epo) concentrations and umbilical cord pH in high risk pregnancies. METHODS: We measured epo concentrations and gas in 103 cases of cord blood obtained from 88 cesarean section (15 of twin) composed of 39 cases of normal control (12 of normal twins), 45 cases of high risk pregnancies and 4 cases of unclassified group using an RIA kit from december,1998 to December, 1999. Statistical analysis was performed using the student's t test and regression analysis. P values less than 0.05 were considered statistically significant. RESULTS: Umbilcal plasma epo concentrations revealed significant inverse correlation (P<0.05) with umbilical acidosis and cord blood epo levels, and it were significantly higher in GDM and IUGR than normal pregnancies (control: 1.60 1.15, n=39 versus GDM: 7.78 7.18, n=11 versus IUGR: 64.77 90.57 n=10, p<0.05), but 11 cases of fetal distress and 13 cases of preeclampsia did not differ significantly from umbilical plasma epo of normal control. CONCLUSIONS: Elevated epo concentrations in cord blood indicate fetal hypoxia and It is significantly increased in IUGR and GDM, these findings show that cord blood epo may serve as a clinically useful marker for chronic fetal hypoxia.
