The influence of prepregnancy body mass index on labor complications.

Abstract: Background. To investigate the influence of Body Mass Index on the incidence of labor complications in a population of women with a normal pregnancy. Material and methods. From a local database, information on maternal weight and height was extracted concerning 4258 women who had an uncomplicated pregnancy. After calculation and stratification with respect to Body Mass Index, this was retrospectively related to labor interventions and complications. Results. High Body Mass Index was related to more oxytocin infusion and early amniotomy, but not to vacuum extraction or cesarean section. Primary inertia and, to a minor degree, cephalopelvic disproportion and secondary inertia were seen more often in women with high Body Mass Index. Conclusions. Overweight (25.0 =30.0) are only weak predictors of labor complications, given a normal pregnancy. However, the heavy use of labor augmentation indicates that obese women should not be recommended to give birth in an ABC-clinic or at home.

Abnormal uterine action in labour.

Abstract: THE reproductive pattern among laboratory mammals shows remarkable variation and none coincides with the human pattern. It seems as though, in the process of evolution, the different species of mammals have modified and adapted the original process handed down to them by their remote ancestors, but in spite of this we can see certaincharacteristics in the pattern of uterine behaviour which they all have in common. For example, uterine activity is small during pregnancy and becomes vigorous only at parturition when the foetus is expelled. Furthermore, in the few mammals which have been investigated it has been found that the reactivity of the uterine muscle to the posterior lobe hormones increases up to the end of pregnancy. If, however, we go beyond these now trite and obvious generalizations we find an embarrassing amount of species difference. For example, the effects produced by the ovarian hormones, the hormones of the adrenal medulla, or by stimulating the nerves going to the uterus, are quite unpredictable from one species to another. Thus it is that the physiologist, although he may be able to examine his problems more ruthlessly and in greater detail than can the clinician, cannot be of direct assistance in the solution of human obstetrical problems. Nevertheless he hopes that he will, eventually, perhaps by the use of new techniques, or by the investigation of the action of hormones, or of new drugs, be able at best to reach an understanding of the process of parturition, or at least provide methods which will allow the obstetrician to obtain a greater control over the process in man.
