Filter by:This is a data base building project on the use of pre-procedure ultrasound for the performance of labor epidural pain relief and spinal anesthesia for cesarean deliveries. Data collection includes ultrasound measured depth, actual needle depth, angle of ultrasound probe, actual needle angle, success rates, patient height and weight, number of attempts needed to place the epidural needle or spinal needle. Currently we are looking at the agreement between ultrasound determined depth of the epidural space or intrathecal space with actual needle depth.
The goal of our research is to increase live birth rates in infertile women and to reduce the incidence of aneuploidy leading to miscarriage and trisomies. We hypothesize that an age related mitochondrial dysfunction reduces the availability of energy in the oocyte and contributes to abnormal segregation of chromosomes during the meiotic division leading to oocyte aneuploidy. Based on preliminary evidence we have obtained in aged mice, we propose that dietary supplementation with Co enzyme Q10 in older women will improve mitochondrial function in the oocytes, leading to a decrease in chromosomal non-disjunction and resulting in embryos with a normal chromosomal complement. Our primary outcome measure will be determination of oocyte chromosome number by multiplex PCR based assay of polar bodies biopsied at the time of IVF. Outcomes of this proposal will enable us to address the mechanisms of ovarian aging and may explain etiology of decreased fertility in older patients. In addition, our work will add to the feasibility of single embryo transfer, thereby avoiding multiple pregnancies and their associated cost to the health care system and to society.
The purpose of this study is to determine if an organized, consistent program of dietary and lifestyle counseling will prevent excessive gestational weight gain.
Fetal heart rate patterns are an important parameter in the diagnosis of non-reassuring fetal status. Combined-spinal epidural analgesia is a method of initiating labor analgesia used by approximately 90% of the parturients at Prentice Women's Hospital. Optimizing the variables which could affect fetal heart rate patterns at the time of initiation of analgesia, such as fluid administration and oxytocin management, could help us provide better care for our patients and their fetuses. Hypotheses: The combination of fluid administration and lower doses of oxytocin administration will have fewer adverse fetal heart rate changes in the first 60 minutes following initiation of labor analgesia.
Randomized controlled trial assessing the benefit of cesarean wound drainage in pregnant women at increased risk of hemorrhage. The pregnant women at increased risk of hemorrhage were randomised in two groups. In one group 2 wound drainages were placed during the cesarean section, in the other group none. Outcome measures were difference between preoperative and postoperative hemoglobin, postoperative fever, cumulative opiate dose adjusted to body weight, length of stay and operation time. It is postulated that the pregnant women with increased risk of hemorrhage do not profit from the routine placement of wound drainages. - Trial with surgical intervention
The primary research hypothesis is that microsurgical varicocelectomy will result in an increase in live birth in infertile couples where the male partner has a palpable varicocele and an abnormal semen analysis in comparison to male partners who do not have microsurgical varicocelectomy. The secondary hypotheses include: 1. To assess whether up to 4 cycles of intrauterine insemination confers any additional increase in live birth rates compared to timed intercourse; 2. To examine spousal pregnancy rate as the secondary outcome; and 3. To study the effect of varicocelectomy in men with infertility, an abnormal semen analysis, and a palpable varicocele on - Testicular semen analysis parameters; - Serological measures of FSH, LH, total and free testosterone and - Measures of quality of life and sexual function in both partners.
The present study is designed to test the hypothesis that acupuncture, before and after embryo transfer, significantly improves pregnancy rates, compared to embryo transfer with sham acupuncture and no acupuncture at all.
The purpose of this study is to evaluate whether manual removal of the placenta during a cesarean delivery results in higher changes in the resistance of blood flow throughout the body, also called systemic vascular resistance (SVR)
This is a prospective randomized cohort study of obstetric patients from Paley clinic at AEMC and from other affiliated obstetric clinics. This study will try to determine if active management of risks in pregnancy at term by inducing patients will not decrease the cesarean delivery rate or change neonatal outcomes. The outcomes that will be measured include cesarean delivery rate, meconium, Apgar scores and admissions to the NICU.
Type 1 diabetic women have a decrease in insulin requirements during early pregnancy. Preliminary evidence suggests this decrease may be secondary to the regeneration of pancreatic B-cells during pregnancy During the second and third trimesters, insulin requirements in Type 1 diabetic women progressively increase until approximately 36 weeks gestation at which time there is a plateau, and frequently, a drop in insulin requirements. We hypothesize that there is regeneration of pancreatic islet cell mass in Type 1 diabetic women during pregnancy. In a cross-sectional study, we will use the acute insulin c-peptide response to arginine to determine if pancreatic islet mass increases at 12 and 36 weeks gestation. Type 1 diabetic women who are not pregnant, who are at 12 and 36 weeks gestation, and who are 6 weeks post-partum will undergo an intravenous arginine tolerance test following an overnight fast. If we find that there is regeneration of beta cells it opens the possibility that therapy may be directed to the same end for people with Type 1 diabetes.
