2006 Oct;30(5):276-87. doi: 10.1053/j.semperi.2006.07.009. Whereas in twin gestations tracings from each infant may be synchronous, absolutely identical tracings do not present as a clinical problem. Some practitioners prefer to delay administration of oxytocin until after the delivery of the placenta in order to avoid its entrapment. In Keith LG, Papiernik E, Keith DM, Luke B (eds): Multiple Pregnancy: Epidemiology, Gestation and Perinatal Outcome, pp 517 – 525. The use of paracervical block is no longer favored because of its association with fetal bradycardia. If sufficient time is indeed present and if the result shows fetal acidosis, a decision must be made to undertake immediate vaginal delivery or cesarean section.
In the absence of ultrasonography to continuously monitor position and FHR, external cephalic version is considered potentially unsafe by many physicians.
Newer technology permits monitoring both twins simultaneously, by the external and/or internal route. The characteristics of labor in twins are not well studied, aside from a recent analysis of normal and abnormal labor patterns by Friedman.11 As Friedman put it, “conflicting information abounds.” Gravidas with twin pregnancies are reported to have short labors or unduly long ones, depending on the source of information.

Preparing for the delivery of twins should be done well in advance. 64) of the American College of Obstetricians and Gynecologists stated that data were insufficient to evaluate the safety of this delivery modality in twins, subsequent reports support this practice. Registered users can save articles, searches, and manage email alerts. In this article, the management of the labor and delivery of multiple gestation are reviewed.
An extraand labour are potentially hazardous … The acute onset of bradycardia in one twin should always alert the caregiver to check the maternal pulse immediately to determine if the mother's heart rate differs from the rate of bradycardia: if this latter rate is identical to the rate of bradycardia, the transducers can then be adjusted until the two FHRs reappear.
It had been decided that during pregnancy has serious implications for delivery should be by Caesarean section and the the anaesthetic management of labour and patient requested extradural anaesthesia. Significant Birth Trauma for 362 Consecutive Twin Gestations, Fig. Selection of the skin incision may be dictated by the reason for the section.
London, Parthenon Publishing Group, 1995). Epub 2018 May 12. Maternal and perinatal outcome in pregnancies complicated with hypertensive disorder of pregnancy: a seven year experience of a tertiary care center.
TABLE 2. Friedman further observed that this issue may be of less clinical importance than it was in the past, because so many women with twin pregnancies (44% to 52%) are delivered by cesarean section.11.
The potential benefit to the fetus should always be considered in light of the risks of cesarean delivery in terms of maternal morbidity or mortality. In Keith LG, Papiernik E, Keith DM, Luke B (eds): Multiple Pregnancy: Epidemiology, Gestation and Perinatal Outcome, pp 503 – 516.
Whereas breech extraction was not enthusiastically endorsed some years ago, several more recent reports now describe it as appropriate, especially if the second twin is breech. Multiple births account for an increasing percentage of low-birth-weight infants, preterm births, and infant mortality. London, Parthenon Publishing Group, 1995), (Chervenak FA, Johnson RE, Youcha S et al: Intrapartum management of twin gestation. Second, they deal only with the duration of labor from the onset to delivery as the measured endpoint.11 As those who have become familiar with the graphic analysis of labor in the last three decades know, it is reasonable to suggest that total duration is a crude means for assessing progress because it ignores subtle and often not so subtle alterations in labor patterns. To enhance patient safety and acceptability, regional blocks should be administered by those who are experienced in administration of epidural analgesia for normal deliveries.4 In the case of twins, analgesic blocks should not be started until obstetric conditions are appropriate (i.e., frequent, strong uterine contractions producing an adequate rate of cervical dilation).4 Many services place the catheter early on, but delay delivery of the anesthetic dose until conditions are deemed favorable.
Over the past 20 years, the number and rate of multiple births have dramatically increased in the United States. In two of the unsuccessful attempts at positional change, the weight of twin B exceeded that of twin A by 500 g or more. 2007;47(2):64-9. doi: 10.1159/000100334.

Labor Data, 50 Pairs of Multiparous Singletons and Twins Matched by Maternal Age, Parity, Fetal Weight (Presenting Fetuses), Fetal Position, Analgesic Effect, Uterotonic Stimulation, and Conduction Anesthesia, TABLE 4. It is important to remember that if the version attempt fails, breech extraction may be more difficult.9 A factor that strongly influences the success of version attempts is the degree to which the uterus contracts after the delivery of the first twin.
