Menstrual patterns and progesterone circulating levels following different procedures of tubal occlusion.

This study was undertaken to assess the effects of different tubal occlusion procedures on ovarian function. Three groups of subjects randomized to tubal occlusion by laparoscopy and Yoon ring (24 subjects), minilaparotomy and Yoon ring (19 subjects) and minilaparotomy and Pomeroy (22 subjects), and one separate control group of 26 healthy subjects not using any form of contraception were studied in a prospective design. The characteristics of the menstrual patterns were studied for one year after sterilization. Determination of the circulating progesterone levels were made on days 15, 20 and 25 of menstrual cycles initiated 1, 3, 6 and 12 months following the tubal ligation. In the analysis of the bleeding pattern there was a statistically significant difference in the mean segment length and in the longest bleeding-free interval in the subjects who had been sterilized by minilaparotomy with Yoon ring, when compared to the other two study groups and to the control group. However, the magnitude of this difference in number of days was not considered clinically significant. There was no statistically significant difference in the percentage of ovulatory cycles within the study and the control groups, or when the results of the study groups were compared with each other or to the control group.

The characteristics of the menstrual patterns were studied for 1 year after sterilization. Determination of the circulating progesterone levels were made on days 15, 20, and 25 of menstrual cycles initiated 1,3,6 and 12 months following the tubal ligation. In the analysis of the bleeding pattern there was a statistically significant difference in the mean segment length and in the longest bleeding-free interval in the subjects who had been sterilized by minilaparotomy with Yoon ring, when compared to the other 2 study groups and to the control group.

The use of biodegradable norethisterone implants as a 6-month contraceptive system.

The effects of a 6-month contraceptive system of biodegradable norethisterone (NET) implants on the menstrual cycle, estradiol and progesterone levels, the presence of side effects, its contraceptive effectiveness, and the NET levels achieved were studied in a group of nine women. There was practically no disruption of the menstrual cycle and no important side effects. Ovulation was inhibited in four subjects, and another four subjects remained ovulatory. In all the subjects a cyclic secretion of estradiol was maintained. No pregnancies occurred. The circulatory levels of NET were very stable throughout the 6-month period of implant use.

Uso de tartrato de butorfanol como analgesico en salpingoclasia con anestesia local. / Use of butorphamol tartrate as analgesic in salpingography with local anesthesia

Este estudio fue disenado para determinar la utilidad del tartrato de butorfanol como analgesico en los precedimientos de esterilizacion femenina con anestesia local.Un grupo de mujeres aleatoriamente distribuidas fueron esterilizadas bajo anestesia peridural o local. En los casos de anestesia local una dosis de 4 mg de tartrato de butorfanol fue usada como analgesico. Los procedimientos empleados fueron laparoscopia y minilaparotomia, usando anestesia local y analgesia en 34 sujetos y bloqueo peridural en 31. Cuarenta casos fueron de intervalo y 25 postparto. La presencia de dolor severo en el transoperatorio se observo en ocho de los 34 casos operados con anestesia local y en dos de los 31 operados con anestesia peridural. En ningun caso la presencia de dolor impidio o dificulto el procedimiento
