201. A French randomized controlled trial of ST-segment analysis in a population with abnormal cardiotocograms during labor (Abstract)

A French randomized controlled trial of ST-segment analysis in a population with abnormal cardiotocograms during labor OBJECTIVE: The purpose of this study was to assess whether knowledge of ST-segment analysis was associated with a reduction in operative deliveries for nonreassuring fetal status (NRFS) or with a need for at least 1 scalp pH during labor. STUDY DESIGN: Seven hundred ninety-nine women at term with abnormal cardiotocography or meconium-stained amniotic fluid (7%) were assigned (...) for NRFS. RESULTS: The operative delivery (cesarean or instrumental) rate for NRFS did not differ between the 2 groups: 33.6% (134/399) in the cardiotocography + STAN analysis group vs 37% (148/400) in the cardiotocography group (relative risk, 0.91; 95% CI, 0.75-1.10). The rate of operative delivery for dystocia was also similar in both groups. The percentage of women whose fetus had at least 1 scalp pH measurement during labor was substantially lower in the group with ST-segment analysis: 27

and 2,697 latent phase women met the study criteria. More latent phase women were nulliparous (51 compared with 28%). Latent phase women had more cesarean deliveries (nulliparas 14.2% compared with 6.7%, multiparas 3.1% compared with 1.4%). Controlling for parity, latent phase women had more active phase arrest (odds ratio [OR] 2.2), oxytocin use (OR 2.3), scalp pH performed (OR 2.2), intrauterine pressure catheter placed (OR = 2.2), fetal scalp electrocardiogram monitoring (OR = 1.7), and amnionitis

203. Delayed pushing with lumbar epidural analgesia in labour. (Abstract)

Delayed pushing with lumbar epidural analgesia in labour. Seventy-six primigravidae with epidural analgesia were randomly assigned to one of two groups for management in the second stage. In one group the women delayed pushing and in the other they were managed conventionally. The two groups were well matched for maternal and infant characteristics, including position and level of the presenting part at full dilatation and fetal scalp blood pH. The mean waiting time in the second stage before (...) pushing was increased from 27 min in the conventional group to 123 min in the delayed group. This delay was not associated with an increase in abnormal fetal heart rate abnormalities or any decrease in umbilical cord pH or Apgar scores. In contrast, the delay was associated with an increase in spontaneous deliveries and a decrease in forceps deliveries (P = 0.06). These findings suggest a need for redefining the management of the second stage of labour with epidural analgesia.

204. Immediate maternal and neonatal effects of low-forceps delivery according to the new criteria of The American College of Obstetricians and Gynecologists compared with spontaneous vaginal delivery in term pregnancies. (Abstract)

nulliparous term parturients who were randomly allocated to spontaneous or elective low-forceps delivery. Patients with either maternal or fetal disorders that could affect the outcome were excluded. All deliveries were attended by three experienced obstetricians.Spontaneous and forceps delivery group were similar regarding maternal or gestational age, fetal scalp pH, antepartum maternal hemoglobin and hematocrit levels, maternal outcome, mean birth weight, and number of neonates with low Apgar scores (...) or cord arterial pH < 7.20. In the spontaneous delivery group the time elapsed since randomization to delivery was significantly longer (18 vs 10.2 minutes, p < 0.001) and the mean cord arterial pH was significantly lower (7.23 vs 7.27, p = 0.01) than in the forceps delivery group.Elective low forceps delivery may be used to shorten the second stage of labor without immediate maternal or neonatal side effects.

205. STAN – ST Waveform Analysis Combined With Cardiotocography for Fetal Monitoring During Childbirth

, it provides only an on-the-spot account. Since the situation can change quickly, there may be a need to repeat the test. STAN combines CTG with ST waveform analysis, ie, analysis of that part of the fetal ECG called the ST segment, which changes if the fetus experiences hypoxia (oxygen deficiency). Hence, STAN technology uses CTG to identify a high-risk group. The method is intended for fetal monitoring during childbirth when it has been determined that continuous monitoring via a scalp electrode (...) is necessary to obtain satisfactory information. This applies to an estimated 20 percent of all deliveries. In contrast to testing scalp blood, STAN continuously monitors the fetus. However, the method is not free from sources of error. For example, even without oxygen deficiency, fetal heart malformations and infections may result in abnormal readings. Primary question Can STAN offer better and more cost-effective fetal monitoring by detecting signs of impending oxygen deficiency earlier in the fetus

212. The effects of internal electronic fetal heart rate monitoring on maternal and infant infections in high-risk pregnancies. (Abstract)

The effects of internal electronic fetal heart rate monitoring on maternal and infant infections in high-risk pregnancies. A controlled prospective study of the effects of fetal monitoring on mothers and infants was conducted at Denver General Hospital, Denver, Colorado. A total of 690 high-risk patients in labor were randomly assigned to one of three groups; auscultation alone, electronic fetal monitoring and electronic fetal monitoring with the option to obtain a scalp pH sample. Maternal (...) and neonatal infectious morbidity after vaginal or cesarean delivery was unchanged with internal fetal monitoring. Despite frequent antibiotic prophylaxis (95% cesarean section v. 11% vaginal), cesarean section was the most significant factor associated with increased maternal puerperal infectious morbidity (13.75% cesarean section v. 3.9% vaginal). Although hours of labor, hours of rupture of membranes, hours of internal catheter, number of exams and presence of meconium were not associated with increased

213. The Dublin randomized controlled trial of intrapartum fetal heart rate monitoring. (Abstract)

The Dublin randomized controlled trial of intrapartum fetal heart rate monitoring. In a randomized controlled trial involving 12,964 women, a policy of continuous electronic intrapartum fetal heart monitoring was compared with an alternative policy of intermittent auscultation, both policies including an option to measure fetal scalp blood pH. Women allocated to electronic fetal heart monitoring had shorter labors and received less analgesia. The caesarean delivery rates were 2.4 (...) % for electronic fetal heart monitoring and 2.2% for intermittent auscultation but this small difference arose from the identification of nearly twice as many fetuses with low scalp pH (less than 7.20) in the electronic fetal heart monitoring group. The forceps delivery rate was 8.2% in the electronic fetal heart monitoring group compared with 6.3% in the intermittent auscultation group, and this excess was explained by more instrumental deliveries prompted by fetal heart rate abnormalities. There were 14

214. A study on intrauterine fetal resuscitation with terbutaline. (Abstract)

A study on intrauterine fetal resuscitation with terbutaline. A randomized study on the effect of terbutaline on fetal distress was carried out in 20 patients who showed evidence of ominous fetal heart rate patterns and fetal scalp blood pH values of less than 7.25. Of those, 11 received terbutaline (study group) and nine did not (control group). There was a significant improvement in the acid-base status of the fetus in the study group compared with those in the control group (p less than 0.01 (...) ). No significant maternal or fetal morbidity occurred in the study group. Apgar scores at 1 minute were 7 or greater in 10 of the 11 study subjects whereas only four of the nine control subjects had a score of 7 or greater. These results suggest that terbutaline may become a useful agent in the treatment of intrauterine fetal distress.

fetuses and gestational ages of 26 weeks or greater were eligible for inclusion. The participants were assigned to continuous EFM or intermittent auscultation based on the flip of a coin. Both groups were followed during labor according to the most recent ACOG guidelines. However, fetal scalp blood pH and crossover from one group to the other were not used.A total of 1428 patients were included, 746 in the EFM group and 682 in the auscultation group.

Our data reveal the degree of confidence around the estimate of the likelihood ratio of a stimulation test. The very low negative likelihood ratios warrant the use of these tests when a nonreassuring intrapartum FHR pattern appears. Because these tests are less than perfect, caution is advised; careful continued monitoring with repeat testing during the course of labor should be performed as long as suspicious FHR patterns persist.
