Abstract

Fetal scalp blood sampling technique may affect the results. A system forsimulating fetal blood sampling was constructed so that two sampling techniques could be compared. An air-tight syringe tipped with a blunt needle was filled with fresh umbilical cord blood. The rate of drop formation at the tip was controlled by a small pump. The usual technique - aspiration of individual drops into a tube, transfer into a syringe, and measurement - was compared with collection directly into a small capillary tube or syringe. Differences were found between slow and rapid drop formation rates with the standard technique for pH, oxygen, and carbon dioxide values. No differences were found with the capillary collection technique. The exposure to air in the standard technique can result in erroneous findings, especially when drops of blood form slowly.

Abstract

In ectopic or extrauterine pregnancies, the fertilized egg implants in tissues other than the uterus. Implantation in the ovary is one of the rarest of ectopic pregnancies and is difficult to diagnose. The symptoms, diagnosis, and treatment of 20 cases of ovarian pregnancy are described in this article. The ovarian pregnancies represented 3.3 percent of all ectopic pregnancies at one institution during a 19-year period, a rate similar to that reported in the literature. However, the prevalence in this group increased during the later years. Eighteen of 20 patients used the intrauterine device (IUD) for contraception. Abdominal pain and menstrual irregularity were the most frequently reported symptoms. Ovarian pregnancy leads to increased growth of blood vessels in the ovary, with associated rupture in many cases. Circulatory collapse due to loss of blood occurred in six patients. Thirteen of the 20 cases were suspected of having ectopic pregnancy before surgery, while other ovarian or abdominal disorders were suspected in the rest. Among eight fertile patients who did not continue contraceptive use and who were available for follow-up study, seven had normal pregnancies and one had an ectopic pregnancy which occurred in the fallopian tubes. Ovarian pregnancies may be associated with IUD use because IUDs (untreated with copper or progesterone) may effectively prevent only uterine and tubal pregnancies.

11. The effect of large uterine fibroids on urinary bladder function and symptoms

Abstract

Women who have large uterine fibroid tumors frequently have symptoms suggesting pressure on the urinary bladder, including increased frequency and urgency, and incontinence. Medical opinion is varied as to whether removal of the tumor relieves the symptoms, whether surgery, which removes the nerve stimulation and regulation of the bladder, exacerbates the problems, or whether urinary symptoms are not related to tumor pressure on the bladder. The relationship between tumor size and urinary symptoms was evaluated in 14 women who were treated with hormonal rather than surgical therapy. Gonadotropin-releasing hormone (GnRH), which decreases estrogen secretion, shrinks fibroid tumors, which are estrogen-dependent. The women were aged 39 to 50 and had given birth to between one and four children. Following two months of treatment with GnRH, tumors shrank in size by more than half. This was associated with significant decreases in nocturnal urination, urgency, and frequency in urination during the day. Decreased uterine size did not alter urge incontinence or stress incontinence. Measurements of bladder function such as capacity and pressure rise on filling did not change in response to treatment. The results support the idea that pressure on the bladder caused by uterine fibroid tumors are responsible for urinary difficulties. (Consumer Summary produced by Reliance Medical Information, Inc.)
