Evaluation of a feto-pelvic scoring system in the management of breech presentations.

A feto-pelvic scoring system comprising maternal pelvimetric data, estimated fetal weight, type of breech presentation and previous obstetric history was used in selecting patients for cesarean section of vaginal delivery. A maximum score of 20 points was possible. Twelve points or less indicated cesarean section. During 1973-1975 224 singleton breech deliveries were evaluated. In 29.5% cesarean section was performed and in 83% of these it could be planned in advance. In 70.5% of cases, patients were allowed to deliver vaginally under continuous electronic monitoring of the fetal heart rate. There was one intrapartum death and only one early neonatal death of a small premature child. In two cases intrauterine death had occurred already in the antepartum period. The uncorrected perinatal mortality was 17.9 per 1000 but not significantly different from the uncorrected perinatal mortality of 8.0 per 1000 for all patients delivered at the Danderyd's Hospital during the period 1972-1975 (12832 births). The corrected mortality resulting from breech presentation was 8.9 per 1000. The infants exhibited similar and excellent 5 min Apgar scores whether delivered vaginally or by cesarean section or matched with a randomized control series of 1000 cephalic presentations.

Spontaneous labor and elective induction--a prospective randomized study. I. Effects on mother and fetus.

In a prospective randomized study spontaneous and oxytocin induced labor "for convenience" have been compared with respect to uterine activity, duration of labor, the condition of the fetus and the newborn infant. The study consists of 84 normal patients, of whom 43 were induced at full term by amniotomy and oxytocin infusion using the Cardiff Infusion System Mark II; 41 patients served as controls. No difference in maternal age, number of previous pregnancies and pelvic score one week before the day of delivery were found between the groups. The following parameters were calculated: duration of labor, uterine activity, amount of bleeding in the third stage of labor, number of early and late decelerations as well as number of episodes of bradycardia in the CTG-recordings, birth weight, Apgar score one and five minutes post-delivery and blood gases in mother and child 60 seconds after delivery. No significant differences between the two groups were found. It is concluded that there are no increased risks to mother or fetus compared to normal labor provided that there is cephalic presentation and normal pregnancy, careful selection with respect to the length of pregnancy and the condition of the cervix and that the Cardiff infusion system is used with intrauterine pressure recording and continuous fetal heart monitoring.

The sub-pubic angle in adult indigenous Malawian subjects.

BACKGROUND: A number of parameters are used to assess the pelvis for clinical, physical and forensic anthropological reasons. When it is adequately assessed within any population group, the pelvis displays wide variations. Although the sub-pubic angle is one of the three forensically important angles of the pelvic outlet, literature is scanty or lacking on East and Central Africans, and no published report is available on indigenous Malawian subjects. OBJECTIVES: To determine the sub-pubic angle in indigenous Malawians and compare them with angles from other population groups previously reported. DESIGN: A cross-sectional study. SETTING: Queen Elizabeth Central and Blantyre Adventist hospitals in the city of Blantyre. SUBJECTS: One hundred and nineteen antero-posterior radiographs of pelves of adults indegenous Malawians aged 20-84 years to determine their sub-pubic angle. RESULTS: Women showed significantly wider sub-pubic angles than men (129.07 +/- 14.190 SD women and 99.16 +/- 15.730 SD men; P < 0.001), confirming similar results previously studied in other population groups. We have demonstrated that the sub-pubic angle alone could accurately assign sex to 67.12% of males and 63.04% of females, and race could be accurately assigned to 21.92% of men and 89.96% of females. Malawians showed significantly wider angles than Amerindians, Black and White Americans (P < 0.001). CONCLUSION: This study documents sexual and racial differences and for the first time (on comparison) the sub-pubic angles indicate geographical variations, underpinning the need to establish normal ranges of these angles in any given population. We recommend the establishment of local references of the sub-pubic angle to other countries in the sub-region.

CAD modeling of the birth process. Part II.

We are engaged in studying the process of human birth by developing a computer-based dynamic model that can be adapted to specific birth scenarios. The individual characteristics of a given pregnant woman and fetus, embedded in their clinical measurements and CT and MRI images, are captured in the model. One can thereby predict adverse events that might happen during labor and delivery. Based on our findings from a preliminary design and execution of this model, we believe it holds great promise as an accurate, cost-effective diagnostic and teaching tool that will help predict conditions during individual labor scenarios that might cause traumatic birth injuries, and thereby enable us to make the most informed clinical decisions possible.
