RESUMEN
OBJECTIVE: The automated gravitational Vario Flow system with weighing-based electronic fluid deficit indicator was used in order to reduce the risk of fluid intravasation during continuous flow hysteroscopic procedures. Early experiences are reported. METHODS: Between August 1996 and July 1997, the Vario Flow with fluid deficit indicator and alarm system was used in 203 hysteroscopic operations. Between January 1994 and August 1996 the Vario Flow without fluid deficit indicator was used in 240 hysteroscopic operations. In all, there were 443 hysteroscopic operations: 301 metroplasties, 20 endometrial ablations, 10 cases of lysis of synechiae, 58 myomectomies and 54 polypectomies. The data on fluid deficit before and after the introduction of the electronic fluid deficit indicator were similar. RESULTS: Fluid deficit indicator was proved highly efficient in 203 operations. It provided the information on fluid deficit at any moment during hysteroscopic operations. Besides intrauterine pressure, the actual fluid deficit has become one of the leading parameters during our continuous flow hysteroscopic procedures. CONCLUSIONS: We therefore conclude that by using an automated gravitational system with fluid deficit indicator and alarm system, the safety for patients during hysteroscopic procedures has been increased.

At present, the less invasive ultrasound-directed techniques are the methods of choice for oocyte retrieval in most in vitro fertilization and embryo transfer (FIVET) centers. Among the ultrasound-direct techniques, the transvaginal follicle aspiration guided by transvaginal ultrasound for oocyte recovery is gaining popularity in many FIVET centers. This study compare cycles outcome following transvaginal ultrasound oocyte retrieval (105 cycles) to laparoscopic oocyte retrieval (218 cycles); no statistically significant difference could be demonstrated between the groups in all parameters evaluated but better clinical results have been obtained in transvaginal ultrasound group. The Authors conclude that transvaginal oocyte recovery represents an improvement and a simplification of the FIVET procedure.

Results of the IVF-ET programme from June 1983 to July 1984 are presented. The procedure was performed in 98 women in 127 cycles. Six normally ongoing clinical pregnancies, three early spontaneous abortions and six biochemical pregnancies were achieved. The laparoscopic techniques of oocyte retrieval were used. Ovulation was first stimulated by clomiphene citrate and later on by gonadotropins only. Comparison of these two regimens showed gonadotropin stimulation to be more effective than clomiphene stimulation, considering the respective transfer rate of 73.3% (gonadotropins) and 18.8% (clomiphene).

Within the in vitro fertilization and embryo transfer procedure, 127 laparoscopies were performed in 89 women. The only indication was tubal infertility. There were 116 gonadotropin stimulated cycles and 11 clomiphene citrate stimulated cycles. Because of a limited ovarian access laparoscopic adhesiolysis was necessary in 30%. Egg recovery amounted to 440 oocytes in 92% successful laparoscopies, which represents 4.1 oocytes per laparoscopy. This resulted in 15 pregnancies of which 3 ended with spontaneous abortion, 6 biochemical and 6 ongoing pregnancies. Two pregnancies resulted in the live birth of normal twins, and one in the birth of a healthy girl.

The study covered a total of 1,488 pregnant women who came for their first prenatal consultations in about the 19th week of pregnancy. The experimental group consisted of 416 women previous pregnancy ended with artificial abortion. In the control groups there were women who had neither a delivery nor abortion, then women whose previous pregnancy ended with the birth of a live child, and, finally, women in whom the previous pregnancy ended with spontaneous abortion. It has been shown that after artificial abortion, spontaneous abortion and premature deliveries in the subsequent pregnancy are just as frequent as in women who have not been pregnant (ili who had no delivery). Nor was there any higher percentage of low birth-weight children or perinatal mortality. A larger number of newborns weighing at birth less than 2,500 g was observed in women in whom abortion was performed by vacuum aspiration and not by curettage. In women with the abortion performed by vacuum aspiration and becoming pregnant in the first year following abortion, there was a significantly higher number of premature deliveries and low birth-weight children.
