OBJECTIVE: In the Term Breech Trial, the risk of maternal morbidity in women who delivered after planning for a caesarean section (CS) was not significantly different from those who delivered after planning for a vaginal birth. We undertook secondary analyses to determine factors associated with maternal morbidity among 2078 women. METHODS: By using multiple logistic regression analyses, we determined the effect of prelabour CS, CS during early labour, CS during active labour, vaginal birth, and other factors on maternal morbidity. For 1536 women delivered after labour, we determined the effect of variables associated with labour on maternal morbidity. RESULTS: The risk of maternal morbidity was lowest following vaginal birth (odds ratio [OR] 1.0) and highest following CS during active labour (OR 3.33; 95% confidence intervals [CI] 1.75-6.33, P < 0.001). For those delivered after labour, a short active phase of the second stage of labour (< 30 minutes) was associated with the lowest risk of maternal morbidity (OR 0.25; 95% CI 0.11-0.57, P < 0.001). CONCLUSION: For women with a singleton fetus in breech resentation at term, maternal morbidity is lowest following vaginal birth and highest following CS during active labour.

BACKGROUND: The Term Breech Trial compared the safety of planned cesarean and planned vaginal birth for breech presentations at term. The combined outcome of perinatal or neonatal death and serious neonatal morbidity was found to be significantly lower among babies delivered by planned cesarean section. In this study we conducted a cost analysis of the 2 approaches to breech presentations at delivery. METHODS: We used a third-party-payer (i.e., Ministry of Health) perspective. We included all costs for physician services and all hospital-related costs incurred by both the mother and the infant. We collected health care utilization and outcomes for all study participants during the trial. We used only the utilization data from countries with low national rates of perinatal death (< or = 20/1000). Seven hospitals across Canada (4 teaching and 3 community centres) were selected for unit cost calculations. RESULTS: The estimated mean cost of a planned cesarean was significantly lower than that of a planned vaginal birth (7165 dollars v. 8042 dollars per mother and infant; mean difference -877 dollars, 95% credible interval -1286 dollars to -473 dollars). The estimated mean cost of a planned cesarean was lower than that of a planned vaginal birth for both women having a first birth (7255 dollars v. 8440 dollars) and women having had at least one prior birth (7071 dollars v. 7559 dollars). Although the treatment effect was largest in the subgroup of women having their first child, there was no statistically significant interaction between treatment and parity since the 95% credible intervals for difference in treatment effects between parity equalling zero and parity of one or greater all include zero. INTERPRETATION: Planned cesarean section was found to be less costly than planned vaginal birth for the singleton fetus in a breech presentation at term in the Term Breech Trial.

OBJECTIVE: To compare mothers' views at 2 years postpartum after participation in a randomized trial of planned Caesarean and planned vaginal birth for a singleton fetus in breech presentation at term. STUDY DESIGN: In selected centres in the Term Breech Trial, mothers completed a structured questionnaire at approximately 2 years postpartum to assess their likes and dislikes about their childbirth experiences and their views about their intrapartum care and care providers. RESULTS: Of 1159 mothers from 85 centres, 917 (79.1%) completed a follow-up questionnaire at 2 years postpartum. Baseline information was similar for both the planned Caesarean and planned vaginal birth groups. Planned Caesarean was associated with less worry about the baby's health (P < 0.001). While other differences were noted in likes and dislikes about their childbirth experiences, women's evaluations of the quality of intrapartum care, the helpfulness of staff, and their involvement in decision-making did not differ in the planned Caesarean delivery and planned vaginal birth groups. CONCLUSION: Planned mode of delivery influences aspects of women's evaluations of their childbirth experiences but does not affect evaluations of the quality of intrapartum care, support from care providers, or amount of involvement in decision-making.

OBJECTIVE: This study was undertaken to compare maternal outcomes at 2 years postpartum after planned cesarean section and planned vaginal birth for the singleton fetus in breech presentation at term. STUDY DESIGN: In selected centers in the Term Breech Trial, mothers completed a structured questionnaire at 2 or more years postpartum to determine their health in the previous 3 to 6 months. RESULTS: A total of 917 of 1159 (79.1%) mothers from 85 centers completed a follow-up questionnaire at 2 years postpartum. There were no differences between groups in breast feeding, relationship with child or partner, pain, subsequent pregnancy, incontinence, depression, urinary, menstrual or sexual problems, fatigue, or distressing memories of the birth experience. Planned cesarean section was associated with a higher risk of constipation (P = .02). CONCLUSION: Maternal outcomes at 2 years postpartum are similar after planned cesarean section and planned vaginal birth for the singleton breech fetus at term.

OBJECTIVE: To determine if the decreased risk of adverse perinatal outcome, with a policy of planned caesarean, in the Term Breech Trial, was due to a reduction of problems of labour, problems of delivery or unrelated problems. DESIGN: Secondary analysis of data from the Term Breech Trial, a randomised controlled trial of planned caesarean versus planned vaginal birth for the singleton fetus in frank or complete breech presentation at term. SETTING: Women were recruited from 121 centres in 26 countries. POPULATION: Women who were enrolled in the Term Breech Trial. METHODS: Adverse perinatal outcome was classified as due to labour, due to delivery, due to neither labour nor delivery or unexplained by an experienced obstetrician who was masked to allocation group. The risk of an adverse outcome in each category was compared according to intention to treat and also by actual method of delivery. MAIN OUTCOME MEASURES: Adverse perinatal outcome (excluding lethal congenital anomalies) that was due to labour, due to delivery, due to neither labour nor delivery or unexplained. RESULTS: Planned caesarean was associated with a lower risk of adverse outcome due to both labour (RR 0.14, 95% CI 0.04-0.45, P < 0.001) and delivery (RR 0.37, 95% CI 0.16-0.87, P= 0.03), compared with planned vaginal birth. Prelabour caesarean and caesarean during early labour were associated with the lowest risk and vaginal birth was associated with the highest risk of adverse outcome due to both labour (0%, 0.4% and 2.2%, respectively) and delivery (0.2%, 0% and 3.1%, respectively). CONCLUSIONS: Planned caesarean decreases the risk of adverse perinatal outcome due to both problems of labour and problems of delivery for the singleton fetus in breech presentation at term, compared with planned vaginal birth.

OBJECTIVE: The purpose of this study was to determine whether planned cesarean delivery for the singleton fetus in breech presentation at term reduces the risk of death or neurodevelopmental delay at 2 years of age. STUDY DESIGN: In selected centers in the Term Breech Trial, children were screened for abnormalities at > or =2 years of age with the Ages and Stages Questionnaire, followed by a neurodevelopmental assessment if the Ages and Stages Questionnaire score was abnormal. RESULTS: A total of 923 of 1159 children (79.6%) from 85 centers were followed to 2 years of age. The risk of death or neurodevelopmental delay was no different for the planned cesarean than for the planned vaginal birth groups (14 children [3.1%] vs 13 children [2.8%]; relative risk, 1.09; 95% CI, 0.52- 2.30; P = .85; risk difference, +0.3%; 95% CI, -1.9%, +2.4%). CONCLUSION: Planned cesarean delivery is not associated with a reduction in risk of death or neurodevelopmental delay in children at 2 years of age.

BACKGROUND: In the Term Breech Trial, the risk of adverse perinatal outcome was lower with planned cesarean section versus planned vaginal birth. We undertook secondary analyses to determine factors associated with adverse perinatal outcome. STUDY DESIGN: By using multiple logistic regression analyses, we determined the effect of prelabor cesarean section, cesarean section during early labor, cesarean section during active labor versus vaginal birth, and other factors, on adverse perinatal outcome. For 1384 fetuses delivered after labor, we determined the effect of variables associated with labor on adverse perinatal outcome. RESULTS: The risk of adverse perinatal outcome was lowest with prelabor cesarean section (odds ratio [OR]=0.13) and highest with vaginal birth. For those delivered after labor, labor augmentation (P=.007), birth weight less than 2.8 kg (P=.003), and longer time between pushing and delivery (P<.001) increased the risk, whereas the presence of an experienced clinician at delivery (P=.004) reduced the risk of adverse perinatal outcome. CONCLUSION: Breech infants at term are best delivered by prelabor cesarean section.

CONTEXT: The Term Breech Trial found a significant reduction in adverse perinatal outcomes without an increased risk of immediate maternal morbidity with planned cesarean delivery compared with planned vaginal birth. No randomized controlled trial of planned cesarean delivery has measured benefits and risks of postpartum outcomes months after the birth. OBJECTIVE: To compare maternal outcomes of planned cesarean delivery and planned vaginal birth at 3 months post partum. DESIGN: Follow-up study to the Term Breech Trial, a randomized controlled trial conducted between January 9, 1997, and April 21, 2000. SETTING AND PARTICIPANTS: A total of 1596 of 1940 women from 110 centers worldwide who had a singleton fetus in breech presentation at term responded to a follow-up questionnaire at 3 months post partum. MAIN OUTCOME MEASURES: Breastfeeding; infant health; ease of caring for infant and adjusting to being a new mother; sexual relations and relationship with husband/partner; pain; urinary, flatal, and fecal incontinence; depression; and views regarding childbirth experience and study participation. RESULTS: Baseline information was similar for both the cesarean and vaginal delivery groups. Women in the planned cesarean delivery group were less likely to report urinary incontinence than those in the planned vaginal birth group (36/798 [4.5%] vs 58/797 [7.3%]; relative risk, 0.62; 95% confidence interval, 0.41-0.93). Incontinence of flatus was not different between groups but was less of a problem in the planned cesarean delivery group when it occurred (P =.006). There were no differences between groups in other outcomes. CONCLUSIONS: Planned cesarean delivery for pregnancies with breech presentation at term may result in a lower risk of incontinence and is not associated with an increased risk of other problems for women at 3 months post partum, although the effect on longer-term outcomes is uncertain.

BACKGROUND: For 3-4% of pregnancies, the fetus will be in the breech presentation at term. For most of these women, the approach to delivery is controversial. We did a randomised trial to compare a policy of planned caesarean section with a policy of planned vaginal birth for selected breech-presentation pregnancies. METHODS: At 121 centres in 26 countries, 2088 women with a singleton fetus in a frank or complete breech presentation were randomly assigned planned caesarean section or planned vaginal birth. Women having a vaginal breech delivery had an experienced clinician at the birth. Mothers and infants were followed-up to 6 weeks post partum. The primary outcomes were perinatal mortality, neonatal mortality, or serious neonatal morbidity; and maternal mortality or serious maternal morbidity. Analysis was by intention to treat. FINDINGS: Data were received for 2083 women. Of the 1041 women assigned planned caesarean section, 941 (90.4%) were delivered by caesarean section. Of the 1042 women assigned planned vaginal birth, 591 (56.7%) delivered vaginally. Perinatal mortality, neonatal mortality, or serious neonatal morbidity was significantly lower for the planned caesarean section group than for the planned vaginal birth group (17 of 1039 [1.6%] vs 52 of 1039 [5.0%]; relative risk 0.33 [95% CI 0.19-0.56]; p<0.0001). There were no differences between groups in terms of maternal mortality or serious maternal morbidity (41 of 1041 [3.9%] vs 33 of 1042 [3.2%]; 1.24 [0.79-1.95]; p=0.35). INTERPRETATION: Planned caesarean section is better than planned vaginal birth for the term fetus in the breech presentation; serious maternal complications are similar between the groups.

Cesarean section has become the standard management used by many clinicians for breech presentation in labor. Proof of the superiority of routine cesarean section has been largely circumstantial. Concern over rising cesarean section rates has led to renewed interest in possible alternatives. Protocols have been developed to select which patients may be allowed a trial of labor with frank breech presentation at term. We undertook a prospective clinical trial comparing elective cesarean section with a selective management protocol for the nonfrank breech presentation at term. One hundred five patients with nonfrank breech presentations at term in labor were studied. Seventy (67%) were randomized to a trial of labor and 35 (33%) to elective cesarean section. Of the patients allowed a trial of labor, 31 (44%) were delivered vaginally, and 39 (56%) required cesarean section. The largest single cause of a "failed" trial of labor was inadequate pelvic dimensions on x-ray pelvimetry (23 patients, 59%). Neonatal morbidity assessed by Apgar scores, cord gases, birth injury, and hospital stay was not different for those delivered vaginally or by cesarean section. Maternal morbidity in terms of febrile morbidity, blood transfusion, wound infections, and hospital stay was significantly greater among women delivered by cesarean section. Two of three neonatal deaths occurred in infants with major congenital anomalies. The third infant, apparently normal, died after vaginal delivery. Extensive evaluation suggests the death was attributable to inadequate resuscitation. We conclude that the use of a selective management protocol under controlled conditions is a reasonable alternative to elective cesarean section. Approximately one half of patients allowed a trial of labor may be expected to deliver vaginally with neonatal morbidity comparable to that seen with cesarean section.
