[Automatic tocography using the Cardiff infusion system under cardiotocographic control with the fetal monitor BMT 504].

Clinical results of the induction of labour by means of the Cardiff-equipment. The fetal monitor BMT-504 (VEB Kombinat Mebgerätewerk Zwönitz) has been used as cardiotocographic control unit. Labour has been induced with oxytocin (n = 38) or methyloxytocin (n = 30). 50 deliveries, which where induced by means of intravenous oxytocin infusion enables to be comparate the results. Using the automatic infusion the average induction-delivery interval was 4 hours 14 minutes, the average dosage of tocergic drugs was 2 IW oxytocin or 20 mug methyloxytocin. Using oxytocin for labour induction we found an increase in obstetric operative frequency caused by fetal distress. There where an increase in basal tone of uterine activity in this patients. Therefore we recommend methyloxytocin for the labour induction of high risk pregnancies. The safety factors, which are incorporated in the Cardiff-equipment have many advantages in obstetrical routine work, to determine fetal distress at an earlier stage. The results presented show that with this automatic infusion system labour can induced with even greater efficiency and safety. The equipment is very useful in accordance to the continuous increasing number of planned deliveries.

[The significance of fetal electroencephalography for the diagnosis of fetal disorders].

In typical cardiotocographic and bloodgasanalytic changes indicating fetal hypoxia the fetal electroencephalography shows frequency slowing, voltage suppression and spike activity. This EEG tracings simultaneously appeared with first cardiotocographic signs of fetal distress. It was not possible to recognize disturbances of fetal oxygenation in an earlier stage by EEG monitoring. Fetal EEG is of difficult technique and interpretation. In so far cardiotocography is of higher security, sensibility and easier handling for fetal monitoring. With regard to future improvements in electroencephalographic techniques it seems possible to get additional and more accurate informations for fetal monitoring and about perinatal morbidity.

[Comparative studies of the value of impulse-reception methods of prenatal cardiotocography].

102 pregnant womens have been controlled by means of the various three methods of the antenatal CTG (phonocardiography, ultrasonography and indirect fetal ECG) between the 22th to 41th week. The registered time for each method was ten minutes. Between the 27th to 33th week of the pregnancy the ultrasonography gives the best results. The phonocardiography gives after the 32th week, especially after the 37th week, increasing technical unobjectionable tachograms. There was a good tachografic performans between the 22th to 27th week and after the 35th week by means of indirect fetal ECG. Between the 27th and 34th week this method refuses. The interpretation of indirect fetal ECG or phonocardiotocography, if they are possible, shows clear advantages in antenatal diagnostic of fetal condition.

[Possibilities in modification of the risk to the child in multiple pregnancy and labor].

A comparison of twin deliveries from 1966 to 1971 (140 = 1,23%) and from 1972 to 1974 (65 = 1,07%) indicates a decrease of the uncorrected perinatal mortality from 10,35% to 6,15% caused by early diagnosis, gestation prolonging measures, diagnosis of placental insufficiency and management of delivery. Concerning the first twin the decrease of perinatal mortality was more evident from 7,86% to 1,54% compared with the second twin from 12,86% to 10,77%. Nevertheless the following statement can be made: up to 1971 perinatal mortality was mainly a problem of prematurely born infants; it is changed now to a problem of antenatal mortality of small for date infants. Prematurely birth and mortality of twins may be well influenced by: 1. Early diagnosis. 2. Widely used hospitalisation, beginning from 28 th week of gestation. 3. Widely used cervix-cerclage and uterotocolysis. 4. Intensive antenatal care. 5. Intranatal intensive care of both infants (cardiotocography, blood gas analysis). 6. Limitation of the interval to 5 to 10 minutes. 7. Widened caesarean section indication (breech presentation, small for date infants).

[Cardiotokography, obstetrical decission, and perinatological results].

For clinical use we divide the cardiotocographic parameters in 4 groups with the following percentages for antenatal or intranatal period. Normal criterias (antenatal: 80%; intranatal: 40%) Warn symptoms (antenatal: 5%; intranatal: 10%) Umbilico-placental circulatory disturbances (antenatal: 6%; intranatal: 45%) Signs of hypoxia (antenatal: 9%; intranatal: 5%). Variable decelerations are typically for disturbances in the umbilico-placental circulation. The clinical reasons are as well cord compressions as uterine hyperactivity or supine hypotensive syndrom. A prospective management of labor is possible only by means of CTG. The fetal death during labor is avoidable. The number of fetal micro-blood-samplings was reduced (in our hospital 10%) and the feto-maternal relationship was included. The operative frequency is the result of objective obstetrical decisions. We have before and after introduction of fetal monitoring a constant frequency of caesarean sectio of about 3%. A rise in operative frequency simultaneously with the beginning of fetal monitoring is due by a high operative activity in cases of umbilico-placental circulatory disturbances. The rate of neurological findings in newborn infants can be decreased. This result is not valid in preterm or small for date infants.

[Critical notes on delivery and perinatal mortality in single breech presentation deliveries].

This report deals with 432 single breech presentation deliveries. Caesarean section frequency was 12,3%. As to the vaginal route of delivery, the simple Bracht manoeuvre had been prefered; in recent times, however, the assisted spontaneous delivery with oxytocin-infusion has been introduced. The corrected perinatal mortality was 4,9%. The rate of prematurely born infants amounted to 14,6%. The corrected perinatal mortality of infants up to 2500 g was 3,3%; of full term infants it was 1,4%. The importance of breech presentation delivery as a high risk delivery is being emphasized. Fetal monitoring and blood gas analysis were required. Indications of caesarean section and suggestions for the management of breech presentations were established. Generally caesarean section of primiparae is not recommended. The diminished rate of prematurely born infants is considered to be of great importance for the decrease of perinatal mortality of breech presentation infants. Intensive pregnancy care, widely used uterotocolysis, and cervix-cerclage in cases of breech presentation are recommended.

[Organization of mass-screening for early detection of cervical cancer and its precancerous conditions. I. report: Demonstration of a computer assisted mass-screening program (Model Rostock) (author's transl)].

Gynecological mass-screening leads to a decrease of prevalence and incidence of cervical cancer and precancerous conditions. In Rostock a program for early detection of cervical cancer was developed. Organization, application of computer in this model and the expenses of a computer assisted mass-screening-program are discussed. In order to facilitate comparison between various centers, a generally accepted classification and terminology of colposcopic, cytologic and histologic findings are essential. First epidemiological results of Rostock's women are demonstrated to characterize the screened population.

[Organization of mass-screening for early detection of cervical cancer and its precancerous conditions. II. report: Practical experience with a computer assisted mass-screening program (Model Rostock) (author's transl)].

Two years experiences with a computerassisted program for early detection of prestages and early cervical cancer in Rostock-city are reported. From 43.000 women invited to take part in the examination, 27.028 = 65% finally cooperated. Pathological Pap-smears were found in 134 cases (= 0,52%). Histological examination in 51 cases (= 0,2%) showed 1 Erosio vera (false positive), 9 severe dysplasia, 30 carcinomata in situ, 3 early invasions (microinvasive cancer), 3 microcarcinoma and 5 macrocarcinoma. Accessory findings were seen in 10,2%. A good organized mass-screening-system with unique nomenclature, diagnostic and treatment of cervical cancer and its prestages gives the best supposition to cut down its rate of incidence.
