To estimate the effect of birth-weight difference between the current and index pregnancy on VBAC failure in patients whose prior cesarean was for cephalopelvic disproportion CPD. This was a retrospective cohort study of women with one cesarean for CPD, comparing the rate of VBAC failure in women whose infant was smaller, the same, or larger in the VBAC attempt compared to cesarean.

Univariable, stratified, and multivariable analyses were used. Compared to patients with the same birth weight, a lower birth weight had fewer failed VBAC attempts adjusted odds ratio The indication for prior cesarean has an impact on the success of a subsequent attempt at vaginal birth. The majority of prior publications in this area have focused on the absolute birth weight of the infant in the VBAC attempt and the probability of a successful VBAC.

In this study, we attempt to estimate the effect of birth weight difference between the current and index pregnancy on VBAC failure in patients whose prior cesarean was for cephalopelvic disproportion. This was a secondary analysis of a retrospective, multicenter cohort study of women with a prior cesarean delivery. The study was conducted from Methods of the study have been published in detail previously, but a brief description follows. Three percent of charts were re-extracted for quality control.

Data collected included: maternal demographics, medical and obstetric history, social history, family history, details of the index pregnancy, antepartum course, labor and delivery events, complications, and maternal outcomes. One hundred grams was chosen as a prior study demonstrated a decrease in the odds of successful VBAC for every g increase in birth weight difference.

Receiver operating characteristics ROC curves were generated to evaluate the utility of birth weight difference to predict VBAC failure. Secondary analyses were performed using an exposure of birth weight in the VBAC attempt of g and g greater or less than the cesarean delivery birth weight. As we were primarily interested in viable pregnancies, women were excluded from the analysis if the VBAC birth weight was documented as less than g.

A documented birth weight of less than g for the cesarean was excluded as this was likely to represent a classical cesarean. Because cephalopelvic disproportion can be difficult to diagnose, 7 a secondary analysis of this data set was performed, including women whose diagnoses could have included CPD. These indications were failed induction and non-reassuring fetal status. A failed induction may actually represent CPD, for example in the case of a macrosomic fetus that fails to descend into the pelvis.

Because it is difficult to clarify these subtleties from a retrospective study, we elected to include these indications in secondary analyses. Secondary outcomes examined include uterine rupture, blood transfusions, postpartum fever, and a composite of complications that included uterine rupture, bladder injury, uterine artery laceration, and bowel injury.

Definitions of each outcome may be found in prior publications. Potentially confounding variables of the exposure-outcome association were identified in the stratified analyses.

Multivariable logistic regression models for the primary outcome were then developed to estimate the effect of change in birth weight between the current and index pregnancy on VBAC failure. Birth weight data for both the index and current pregnancy were available in Of these, 1, had one prior cesarean for CPD. An additional 1, had one prior cesarean for failed induction and 1, had one prior cesarean for non-reassuring fetal status. Patients in the three exposure groups smaller birth weight, same birth weight, and larger birth weight were similar with respect to age, gravidity, race, presence of a hypertensive disorder, spontaneous labor, and oxytocin use Table 1.

When grouped according to lower birth weight, same birth weight, or higher birth weight in the VBAC attempt compared to the cesarean, a modest effect of birth weight difference on VBAC failure rate is seen Table 2.

Birth weight was used as a continuous variable to predict the failure of VBAC. The risk of uterine rupture, composite complications, and blood transfusion was not significantly different when lower or higher birth weight was compared to the same birth weight group.

The risk of postpartum fever was lower in the lower birth weight group compared to the same birth weight group The risk of postpartum fever was similar between the higher and same birth weight categories A similar pattern was seen when patients were included whose prior cesarean was performed for failed induction Table 3. The risk of complications in the higher birth weight group was similar to the same birth weight group.

When including patients whose prior cesarean was for CPD, failed induction or nonreassuring fetal status, the risk of failed VBAC was moderately lower in patients whose infant was smaller compared to women whose infants were the same size Table 4.

The risk of complications in the higher birth weight group was similar to the same birth weight. Data not shown, available upon request. In patients whose prior cesarean was for CPD, the effect of incremental increases in birth weight was examined Table 5. A distinct pattern of increased risk of VBAC failure as birth weight gradually increased was not seen.

Thus, these data do not support the presence of a dose-response relationship between birth weight difference and failed VBAC attempt. In this large retrospective cohort, birth weight difference between the VBAC attempt and a prior cesarean for cephalopelvic disproportion had a moderate, though statistically significant, impact on VBAC failure; however, examination of the ROC curve reveals that birth weight difference is not a useful predictor of VBAC failure based on the modest area under the curve and the lack of a clear discriminatory point that could discern those that are destined for VBAC failure.

A similar, though diminished, impact of birth weight difference was seen in patients whose prior cesarean was performed for failed induction and non-reassuring fetal status. Therefore, we conclude that the effect of birth weight difference is small and should not be used as a critical factor in deciding whether VBAC should be attempted.

Allowing women with a larger infant than their prior pregnancy to attempt VBAC does not seem to increase the risk of complications. Since actual birth weight does not generate a clinically useful prediction model for predicting failed VBAC, we anticipate that ultrasound-based estimated fetal weight will not either.

Several prior studies have examined the effect of macrosomia on VBAC success. Zelop et al found that a macrosomic fetus was associated with a decreased rate of VBAC success and no change in the risk of uterine rupture. Although informative about the impact of macrosomia on VBAC, these studies do not include information about the impact of birth weight difference. In a secondary analysis of a large prospective cohort study, Peaceman et al found that as the birth weight difference between the VBAC attempt and prior cesarean increased, the rate of VBAC success fell.

One of the main differences between their study and ours was the definition of the exposure; Peaceman et al included failed induction as part of CPD, whereas we analyzed this in a secondary analysis as failed inductions may or may not represent a subset of CPD patients.

The strengths of this study are its large size and comprehensive clinical data available, allowing us to examine outcomes, including maternal complications, in this very specific subset of patients. Also, we analyzed patients with a prior cesarean for failed induction or non-reassuring fetal status separately, as these may or may not represent cases of cephalopelvic disproportion.

An inherent limitation of a retrospective study is the possibility of selection bias. This type of selection bias may have diminished the observed impact of a larger infant on the rate of VBAC failure. Also, as the birth weight difference increased, the number of patients attempting VBAC decreased, thus limiting our power to detect a difference. As this cohort was designed to investigate maternal risks associated with VBAC, we were unable to examine infant outcomes.

Although we have extensive information available regarding maternal co-morbidities, information on maternal body mass index BMI , which has been noted to be a variable affecting VBAC success, is unavailable in this cohort. Despite these limitations, we feel that clinically important conclusions can be drawn. Although birth weight difference modestly impacts VBAC success in patients with a prior cesarean for CPD, evaluation of birth weight difference incrementally and the ROC curve did not reveal a clear cutoff where the risk of failed VBAC became unacceptable.

Therefore, we conclude that although VBAC failure increases moderately as VBAC birth weight increases over the index cesarean birth weight, we cannot make recommendations on a difference over which VBAC should not be attempted.
