Is Transient Bradycardia Following Cordocentesis Associated with Adverse Pregnancy Outcome? / 대한산부인과학회잡지

OBJECTIVE: To evaluate the association between transient bradycardia following cordocentesis and adverse pregnancy outcome. METHODS: 117 cordocentesis was performed at Samsung Cheil hospital and women's healthcare center, between January 1, 2000, and December 31, 2002. Clinically significant bradycardia was defined as a drop in the heart rate to less than 120 bpm. The adverse outcome included major anomaly, chromosomal abnormality, intrauterine growth restriction, preterm birth, and intrauterine fetal death. RESULTS: Bradycardia following cordocentesis was observed in 13 cases (11.1 per cent). The fetal heart rate before (149.2 +/- 0.7 bpm) and after (144.7 +/- 2.8 bpm) cordocenteis was significantly different. The adverse outcome rate was 50.0 per cent (6/12) in cases with bradycardia and 27.7 per cent (26/94) in those without bradycardia (RR=2.6, P=NS). CONCLUSION: Our result is that the association between transient bradycardia following cordocentesis and adverse pregnancy isn't statistically significant, even though adverse outcome is more frequent in pateints with bradycaredia. Therefore, patient with bradycardia following cordocentesis need periodic fetal surveillance.

Midtrimester pregnancy termination with prostaglandin E1 Misoprostol compared with physician-chosen combination method; A prospective randomized trial / 대한산부인과학회잡지

OBJECTIVE: The purpose of this study was to determine the effectiveness and safety of misoprostol in termination of pregnancy. MATERIALS & METHODS: 38 women who presented with indication for termination of pregnancy were assigned randomly to receive either 200 microgram of misoprostol orally every 4 hours as needed, or medication according to the our established protocol (physician-chosen combinations of Sulprostone infusion every 6 hours with vaginal PGE2 or Laminaria). Exclusion criteria were history of asthma, glaucoma, cardiac or hepatic disease, or chorioamnionitis. Unless delivery had occurred or was imminent after 24 hours with medication, the case was considered to have failed. The induction to delivery time and influencing factors were analyzed in both group using t-test, chi-square test or Fisher`s exact test, Kaplan-Meier and Cox regression. RESULTS: The success rate of termination of pregnancy within 12 hours and 24 hours were 67% and 93% with misoprostol (n=15) versus 5% and 43% with physician-chosen combination (n=21) (p<0.05). Among 3 cases failed with misoprostol within 24 hours, two cases crossed to the alternative method after 24 hours of misoprostol, so, the 2 cases were excluded. The mean dosage and frequency of misoprostol was 540 microgram and 2.8 times. The mean induction to delivery time ( mean +/- standard deviation) with oral misoprostol (n=15) was 640+/-590 minutes versus 1670+/-750 minutes with physician-chosen combination (n=21) (p<0.001).

Fetal outcome following transabdominal amnioinfusion in various causes of oligohydramnios / 대한산부인과학회잡지

OBJECTIVE: To evaluate the efficiency and fetal outcome following antepartum transabdominal amnioinfusion in various causes of oligohydramnios. MATERIALS AND METHODS: Forty four transabdominal amnioinfusion were performed in twenty seven cases of singleton pregnancy with severe oligohydramnios. Severe oligohyadrmnios defined as amnionic fliud index of 5cm or less than. In all cases, high resolution sonographies were done before and after amnioinfusion in order to detect fetal anomalies. Transabdominal amnioinfusion was performed through a closed system with warmed normal saline. RESULTS: Infusion (mean volume 435.9ml) of normal saline significantly increased the amniotic fluid index from 3.2cm to 7.5cm. The causes of oligohydramnios were as follows, premature rupture of membranes was 8 cases (29.6%), intrauterine growth restriction was 10 cases (37.0%), congenital anomaly was 4 cases (14.8%) and idiopathic was 5 cases (18.5%). The gestational weeks were prolonged significantly from 26.8 weeks to 29.5 weeks. The overall survival rate except congenital anomalies was 67%. Babies with idiopathic oligohydramnios were heavier and required less hospitalization dates than those of badies with oligohydramnios of other causes, but it was not statistically significant. There were several complications as follows, chorioamnionitis 2 cases, neonatal sepsis 2 cases, meconium aspiration syndrome 2 cases and fetal bradycardia 1 case. All of the babies discharged healthy without sequele. CONCLUSION: These results show that antepartum transabdominal amnioinfusion is a relatively safe procedure. And it can significantly increase the amnionic fluid index and prolong the gestational age which is optimal for neonatal survival in oligohydramnios of idiopathic cause or with intrauterine growth restriction.
