    Objective: The objective of the study was to determine whether epidural placement before engagement of the fetal head is associated with an increase in the incidence of malposition at delivery. Study Design: We performed a retrospective cohort study to ascertain the relation between station at epidural placement and malposition. Three hundred fifty-seven patient records were reviewed;   The sliding mechanism at the articulation can be helpful in asynclitic births (when the fetal head is tilted to the side), since the fetal head is no longer in line with the birth canal. Because the handles, shanks and blades are all in the same plane the forceps can be applied in any position to effect rotation. Because the shanks and handles

    Discussion. It is important to evaluate the efficacy of maternal position to correct fetal OP position during the first stage of the labour. Although these positions seem to be well accepted by women and appear easy to implement in the delivery room, the sample size of the last randomised clinical trial published in to evaluate this intervention had insufficient power to demonstrate clear The results obtained on the lumbopelvic position during standing are consistent with previous studies [11,13,14, 16] in which no differences were observed in the degrees of lumbar curvature of

METHODS Eighteen preterm infants with clinically significant GOR were studied prospectively using 24 hour lower oesophageal pH monitoring. Infants were nursed in three positions (prone, left, and right lateral) for 8 hours in each position, with the order randomly ://

This need is particularly important when considering fetal interventions and potential pregnancy effect of maternal lumbar curvature on fetal position book, the latter of which has become subject to increasingly stringent government regulation.

However, we are unable to control fetal position to attain this end. We also cannot control maternal body habitus or the amount of amniotic fluid, both of which may dramatically alter our ability to discern fetal ://   The position of the legs, thighs and curvature of the lumbar spine, affect obstetrical mechanics, as Aspasia, a midwife and Pericles’ partner, pointed out two and a half millennia ago (cited by Aetius Amidenus, original classical Greek text in Appendix A): “If the difficulty comes from the curvature of the lumbar region, he (the physician   Aspasia was noting the position of the legs, thighs and curvature of the lumbar spine and how this position affected the physics of birthing by letting the baby find room to descend.

Fetal presentation is a reference to the part of the fetus that is overlying the maternal pelvic :// While measuring fetal T in humans is infeasible, demonstrating in utero androgen exposure using a reliable newborn biomarker, anogenital distance (AGD), would provide evidence for a fetal origin of PCOS and potentially identify girls at risk.

Using data from a pregnancy cohort (The Infant Development and Environment Study), we tested the novel   Results. Lumbar lordosis was decreased in patients with CNLBP during STS and SIT compared with the asymptomatic group (mean difference = °°; P ≤).

Furthermore, no differences were seen in lumbar lordosis at starting position between CNLBP and asymptomatic groups during STS and SIT (mean difference = °°; P ≥).). Interestingly, the magnitude of the effect • Limited space at the inlet & progressively lessens down the pelvis, owing to the funneling effect of the side walls, sacrum, and pubic rami.

• Restricted space at all levels. • The fetal head is forced to be in the occipitoposterior position to conform to the narrow anterior pelvis. Keywords: Fetal head position, Occipito-posterior, Maternal position, Randomised controlled trial, Second stage of labour Background During the first stage of labour, 10% to 34% of fetuses are in occipito-posterior (OP) position (Figure 1) [].

A cohort study of 1, nulliparous women reported an association between epidural analgesia and OP During fetal development, the body is flexed anteriorly into the fetal position, giving the entire vertebral column a single curvature that is concave anteriorly.

In the adult, this primary curvature is retained in two regions of the vertebral column as the thoracic curve, which involves the thoracic vertebrae, and the sacrococcygeal curve ion/aandp/chapter/the-vertebral-column. This misalignment increases the lumbar curvature and stretches and weakens all of the abdominal muscles.

Pressure against the interior abdominal walls subsequently both separates the rectus abdominus at the linea alba (diastus recti) and incites hyperirritable, tender points (myofascial trigger points) in the abdominal muscles that   fetal spine against the lumbar curve of the maternal spine.

This makes the fetus straighten its neck and adopt a more erect attitude. On auscultation The fetal back is not well flexed so the chest is thrust forward, therefore the fetal heart can be heard in the midline. However, the heart may be heard more easily at the flank on the same side Christina L.
