At 6 weeks postpartum, more women who were randomly assigned to high-dose epidural fentanyl were not breast-feeding (n = 10, 17%) than women who were randomly assigned to receive either an intermediate fentanyl dose (n = 3, 5%) or no fentanyl (n = 1, 2%) (P = 0.005). Conclusion: Among women who breast-fed previously, those who were randomly assigned to receive high-dose labor epidural fentanyl were more likely to have stopped breast-feeding 6 weeks postpartum than women who were randomly assigned to receive less fentanyl or no fentanyl.

The temperature measured when the newborns were put skin-to-skin on their mothers' chest was significantly higher in the infants of the EDA group (35.07 degrees C) when compared to the control group (34.19 degrees C, p=0.025). Skin temperature increased significantly (p=0.001) during the entire experimental period in the infants belonging to the control group. The same response was observed in infants whose mothers received OT intravenously during labour (p=0.008). No such rise was observed in infants whose mothers were given an EDA during labour.

Smith / BFLRC 4/8/2015 Elective Cesarean: BF to a lesser extent at 3 months In a prospective cohort study 357 healthy primiparas from two different groups, "cesarean section on maternal request" (n=91) and "controls planning a vaginal delivery" (n=266) completed three selfassessment questionnaires in late pregnancy, two days after delivery and 3 months after birth. RESULTS: Women requesting cesarean section experienced their health as less good (p<0.001) and were more often planning for one child only (p<0.001). They more often reported anxiety for lack of support during labor (p<0.001), for loss of control (p<0.001), and concern for fetal injury/death (p<0.001). They were breastfeeding to a lesser extent three months after birth (p<0.001). There were no differences in signs of postpartum depression between the groups three months after birth (p=0.878).

VD mothers' brains were significantly more responsive than CSD mothers' brains to their own baby-cry in the superior and middle temporal gyri, superior frontal gyrus, medial fusiform gyrus, superior parietal lobe, as well as regions of the caudate, thalamus, hypothalamus, amygdala and pons. Also, within preferentially active regions of VD brains, there were correlations across all 12 mothers with out-of-magnet variables. These include correlations between own baby-cry responses in the left and right lenticular nuclei and parental preoccupations (r = .64, p < .05 and .67, p < .05 respectively), as well as in the superior frontal cortex and Beck depression inventory (r = .78, p < .01). this suggests that VD mothers are more sensitive to own baby-cry than CSD mothers in the early postpartum in sensory processing, empathy, arousal, motivation, reward and habit-regulation circuits.

Smith / BFLRC 4/8/2015 Cumulative effect of interventions N=753,895 low-risk women who gave birth in Australia during 2000-2002. RESULTS: We observed increased rates of operative birth in association with each of the interventions offered during the labour process. For first time mothers the association was particularly strong. At a population level it demonstrates the magnitude of the fall in rates of unassisted vaginal birth in association with a cascade of interventions in labour and interventions at birth particularly amongst women with no identified risk markers and having their first baby.

Smith / BFLRC 4/8/2015 Traumatic birth impedes BF RESULTS: n= 52; Eight themes emerged about whether mothers' breast-feeding attempts were promoted or impeded. These themes included (a) proving oneself as a mother: sheer determination to succeed, (b) making up for an awful arrival: atonement to the baby, (c) helping to heal mentally: time-out from the pain in one's head, (d) just one more thing to be violated: mothers' breasts, (e) enduring the physical pain: seeming at times an insurmountable ordeal, (f) dangerous mix: birth trauma and insufficient milk supply, (g) intruding flashbacks: stealing anticipated joy, and (h) disturbing detachment: an empty affair. CONCLUSIONS: The impact of birth trauma on mothers' breast-feeding experiences can lead women down two strikingly different paths. One path can propel women into persevering in breast-feeding, whereas the other path can lead to distressing impediments that curtailed women's breast-feeding attempts. Beck, C. T., & Watson, S.
