Outcome of term breech delivery in primigravidae. a feto peivicbreech index.

Analysis of 340 term breech presentations in primigravidas showed a corrected perinatal mortality of 1.5%; the elective cesarean section rate was 15%. The incidence of complicated labour, defined in the study, was analyzed with regard to different parameters, e.g. X-ray pelvimetry data in all 340 cases. Complicated labour in vaginal deliveries markedly increased with increasing fetal weight (p less than 0.001) and decreasing pelvic capacity (p less than 0.001). In each case the fetal weight and smallest pelvimetry data were given score points and the sum of these was called the Feto Pelvic Breech Index, which was correlated to the incidence of complicated labour. By using this index the mortality and the routine use of elective cesarean section. The prognostic methods available to detect feto-pelvic disproportion are discussed.

A computer method for visual presentation and programmed evaluation of labor.

Manual graphing of the progress of labor is considered useful but is not often done. The early detection of some deviations requires special graphics aids. Our objective was to develop an easy-to-use computer program for the integrated visual presentation of information characterizing the progress of labor. Through the use of inexpensive personal computers equipped with graphics monitors, the program provides a combined graphics display of timed progressive cervical dilatation, fetal station, and stimulation of uterine activity (oxytocin infusion). For the early detection of abnormalities, phase-specific normal ranges (reference areas) are displayed. In addition, protraction/arrest as well as precipitate labor disorders are highlighted and computer messages are displayed. The program was evaluated through the assessment of 405 labors entered into a local area network of computers. On average, the program identified 1.5 abnormalities per recorded labor (2.0 for labors resulting in vaginal delivery). The graphic presentation of the labor curve, produced within 3 seconds, displayed 27% more information than the tabular format on the same screen area and provided a single-screen display of the labor curve even for patients with excessive data. The computer-generated display of labor curves facilitates visual presentation and interpretation of labor progress and can also help to translate quality assurance criteria into clinical practice.

Risk factors for cesarean delivery at presentation of nulliparous patients in labor.

OBJECTIVE: To identify risk factors that place a term nulliparous patient in labor at risk for cesarean delivery. METHODS: This was a case-control, chart review study of 325 nulliparous patients presenting in labor at term with singleton vertex fetuses with either cesarean (patients) or vaginal (controls) delivery. Dichotomous variables were analyzed by chi(2) or Fisher exact tests; continuous variables were assessed by the Wilcoxon two-sample test. Multiple logistic regression was used to identify independent risk factors for cesarean delivery, and a model for predicting risk was built and evaluated. RESULTS: In univariate analysis, 22 variables were significantly different between patients and controls. Of 11 that were known within 2 hours of admission, five (change in cervical dilatation, maternal weight, gestational age, fetal station at 2 hours, and preeclampsia) remained independently significant in a multiple logistic regression model for cesarean delivery. The multiple regression model could divide our study population into quintiles in which the lowest risk group had a 5% incidence and the highest risk group had an 88% incidence of cesarean delivery. CONCLUSION: It may be possible to offer early cesarean delivery to patients at highest risk, reducing the potential morbidity of long labor or failed operative vaginal delivery followed by a later cesarean delivery.
