Background: Detection of women at risk for dystocia will allow physicians to make preparations and treatment decisions that can minimize maternal and neonatal morbidity. We aimed to determine the risk factors for dystocia in nulliparous women. Methods: This case series enrolled 447 nulliparous women who presented with a single pregnancy in the vertex presentation and gestational age of 38-42 we...

Dystocia (DYS) is an important problem in Holstein cattle and imposes important economic losses on cattle producers. The etiologies and types of DYS are various and different factors can influence its incidence. In the present study, incidence of different types of dystocia was investigated in different seasons and parities in Holstein cows. One hundred and eighty two primiand multiparous cows ...

BACKGROUND Dystocia is one of the important causes of maternal morbidity and mortality in low-income countries. This study was aimed to determine the diagnostic accuracy of maternal anthropometric measurements as predictors for dystocia in nulliparous women. MATERIALS AND METHODS This prospective cohort study was conducted on 447 nulliparous women who referred to Omolbanin hospital. Several m...

This study was conducted to determine relative relationships among factors affecting dystocia in Brahman-cross heifers. Body and pelvic measurements were obtained in mid-June (when heifers were approximately 17 mo old), 45 d after a 60-d breeding season. Heifers studied were 207 Red Brangus, 209 Simbrah, and 250 Braford bred to Black Angus bulls; calving began on December 1. Heifers grazed stoc...

Shoulder dystocia is one of the most difficult complications of labor that is often unpredictable and hence unpreventable. In most cases, the cause is dystocia from the bony pelvis. The major brunt of complications is borne by the fetus. In neglected cases, grave maternal complications like obstructed labor and rupture of uterus may result. Very rarely, the reverse, uterine rupture leading to s...

OBJECTIVE To determine whether a customized standard for large for gestational age (LGA) identifies undiagnosed women at risk of operative delivery and shoulder dystocia. METHODS We previously generated customized standards from our institution. We compared the baseline maternal characteristics and neonatal outcomes between LGA and non-LGA births, which were classified by both population-base...

OBJECTIVE The objective of the study was to determine whether a simulation-based educational program would improve residents' and attending physicians' performance in a simulated shoulder dystocia. STUDY DESIGN Seventy-one obstetricians participated in an unanticipated simulated shoulder dystocia, an educational debriefing session, and a subsequent shoulder dystocia simulation. Each simulatio...

Data from 131 calvings of Chianina crossbred cows (2 to 5 yr old) bred to Chianina bulls were used to compare stepwise multiple regression analysis (RA) and stepwise, two-group discriminant analysis (DA) for predicting dystocia. Variables (21) studied in relation to dystocia included both prebreeding and precalving cow and calf effects. Calving was categorized as either unassisted or assisted w...

An observational study was conducted to quantify the effects of management practices on reproductive performance and disorders of beef cows. The study population consisted of 44 randomly selected Colorado cow-calf herds monitored for disease and reproductive events as part of the National Animal Health Monitoring System. The managers of the herds were surveyed with a standardized questionnaire ...
