Hands/knees posture in late pregnancy or labour for fetal malposition (lateral or posterior).

BACKGROUND: Lateral and posterior position of the fetal presenting parts may be associated with more painful, prolonged or obstructed labour and difficult delivery. It is possible that maternal posture may influence fetal position. OBJECTIVES: The objective of this review is to assess the effects of adopting a hands and knees maternal posture in late pregnancy when the presenting part of the fetus is in a lateral or posterior position. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group trials register and the Cochrane Controlled Trials Register. Date of last search: February 1999. SELECTION CRITERIA: Randomised trials of hands and knees maternal posture compared to other postures. DATA COLLECTION AND ANALYSIS: Both reviewers assessed trial eligibility and quality. MAIN RESULTS: One trial involving 100 women was included. Four different postures (four groups of 20 women) were combined for the comparison with the control group of 20 women. Lateral or posterior position of the presenting part of the fetus was less likely to persist following 10 minutes in the hands and knees position compared to a sitting position (relative risk 0.25, 95% confidence interval 0.17 to 0.37). REVIEWER'S CONCLUSIONS: Hands and knees maternal posture for lateral or posterior fetal presentation appears to result in short term effects ion fetal position. No other perinatal or maternal outcomes were reported. There is not enough evidence to evaluate the effectiveness of a hands and knees maternal posture when the fetal presenting part is lateral or posterior, on clinically important outcomes.

The randomized management of term frank breech presentation: vaginal delivery vs. cesarean section.

A prospective study of the management of term frank breech presentation is currently ongoing at LAC-USC Medical Center. To date, 57 patients have been randomized to an elective cesarean section group and 70 to a vaginal delivery group. Of the 70 patients selected for vaginal delivery, 35 had one or more inadequate pelvic measurements by x-ray pelvimetry and were scheduled for indicated cesarean section. Of the remaining 35 patients in this group, 30 delivered vaginally without perinatal death. Two of the infants, however sustained brachial plexus injuries. Of the 57 patients scheduled, 55 underwent elective cesarean section. There were no maternal deaths, but 20 (36.4%) patients experienced morbidity and 5(9.1 per cent) patients experienced intraoperative complications. Based on the data accumulated to date, it seems reasonable to allow vaginal delivery in carefully selected cases of term frank breech presentation.

[Current value, technic and indications for obstetrical operations].

Starting point of this survey is the 1954 paper about obstetrical operations from H. Kraatz. It is demonstrated, that there were and there are defined principles, which continue to exist unchanged. They are the fundamentals of indication and technique of operations in obstetrics. Nevertheless there are distinct changes, too, caused by two factors, progress in medicine (development of antibiotics, anaesthesiology and neonatology) as well as change of aspect in obstetrics (e.g. toxemias of pregnancy, preterm labour). The methods are discussed in detail. Operations by vaginal route come in the foreground in the last years more again. They should be preferred in maternal interest. The enlarged indication for caesarean section was not able to succeed on a large scale. An uniform procedure is proposed both in cephalic and breech presentation, and the new formulated preconditions to these operations are discussed. All three techniques two abdominal ones and one vaginal one) are demanded in caesarean sections, because they come into question in special situations. There is a change in operative indications in cases of bleeding, because of an early diagnosis by ultrasound. The qualification and experience of the obstetrician is more decisive than the selected method of operation or the instrument's type. Therefore there should not be any cut in instruction and training. The versatility of operative technique is a prerequisite to a qualified indication.

[Frequency of breech presentation during pregnancy and on full term (author's transl)].

The causes underlying the relationship between breech presentation and premature birth were studied, with reference to the premature birth discussion which has assumed sizeable dimensions in the obstetric community. -- An evaluation of 785 ultrasonographic findings from pregnant women has shown breech presentation to be just as frequent as vertex presentation up to the 24th week of pregnancy. The former, consequently, should be considered as physiological. The frequency of breech presentation was found to go down continuously only beyond the 24th week and to drop below five per cent, after the 35th week of pregnancy to reach eventually the figure usually recorded at birth. These observations were found to be in good agreement with what has been reported by other authors. -- The authors of this paper were struck by surprise, when they found that the breech presentation figure, in the context of 997 premature births, was, with high significance, below the level usually recordable from unimplanted pregnancy. -- The above findings are discussed in great detail. Preliminary suggestions are made regarding possible interpretations. Yet, further target-oriented studies are required.

Diagnosis and management of face presentation.

Face presentation is an unusual complication of pregnancy; it occurs once in every 500 to 600 deliveries. Prematurity, fetal macrosomia, anencephaly, and cephalopelvic disproportion (CPD) are the major obstetric factors that predispose the fetus to face presentation. Although the mechanisms of labor in face presentation are different from those of simple vertex presentation, there is no consistent alteration in the duration of labor in the absence of underlying CPD. When disproportion does not exist and gross anomalies are not present, the prognosis for spontaneous vaginal delivery is excellent. The majority of perinatal losses reported in face presentation have resulted from traumatic operative vaginal deliveries, specifically version and extraction and midforceps rotations. Recent experience at this institution with a limited series of face presentations demonstrates that, with careful intrapartum surveillance, delivery can be accomplished with no increase in risk to either mother or fetus.
