Risk factors of caesarean section due to cephalopelvic disproportion. J Med Assoc Thai.
The morphometric characteristics of the pelvic cavity are important to be described, so the obstetrician can identify and diagnose cephalopelvic disproportion of a narrow pelvis and correctly indicate a cesarean (Santin).
The 40 cm cut-off can be recommended for general use in southern Africa for term parturients of black African ethnic origin, to identify women at high and low risk of complications such as shoulder dystocia and cephalopelvic disproportion. This adds to findings from a previous study from Pretoria, (13) where a 30 cm cut-off was found useful in predicting birth weights of less than 2 000 g in women in preterm labour.
Women obtaining maternity care from family physicians were less likely to receive epidural anesthesia during labor or an episiotomy after vaginal births, and had a lower rate of cesarean section delivery rates, primarily because of a decreased frequency in the diagnosis of cephalopelvic disproportion. Differences between outcomes persisted after adjustment for potential confounders such as parity, previous cesarean delivery, and use of epidural anesthesia during labor.
Indications for Cesarean sections were fetal distress, cephalopelvic disproportion, repeat lower segment cesarean section, pre eclemptic toxemia, failed progress of labour and intra uterine growth retardation.
* The reason cited for approximately half of the intrapartum cesarean deliveries was "failure to progress" or "cephalopelvic disproportion"; more than one-quarter were performed for indications of nonreassuring fetal testing or fetal distress.
(6) The need for cesarean delivery rises with increasing BMI, probably because of a greater degree of maternal pelvic soft tissue, which increases the risk of both dystocia and cephalopelvic disproportion.
She surmised that the impact of height on delivery probably has "something to do with cephalopelvic disproportion."
Of those, only three were transported--one for pitocin augmentation, one for possible fetal distress, and one for suspected CPD (cephalopelvic disproportion).
Of 224 women who gave birth during the year of this study, 38 had cesarean sections for reasons such as previous section, maternal genital herpes, primigravida breech, cephalopelvic disproportion, and fetal distress; these women were excluded from the study.
Indications for CS 1 Foetal distress 21 (47.7%) 2 IUGR with Doppler changes 12 (27.27%) 3 Failed induction 8 (18.18%) 4 Cephalopelvic disproportion 3 (6.80%) 44 Table 5 Birth Weight No.
Furthermore, failed IOL must be differentiated from failure to progress in labour and from cephalopelvic disproportion or malpresentation.
