[Abortion at 10 to 12 weeks using a plastic syringe or electric aspirator].

The study included 170 women subjected to menstrual regulation. The double-valve band syringe was used in 96 and the electric pump (the vacuum source usually used at the Department) in 74 cases. Nearly all the procedures were performed under general anesthesia, using 8 mm, 10 mm or 12 mm plastic rigid cannulae. Three abortions with the hand syringe also required dilatation and curettage, and all three women suffered blood loss exceeding 100 ml. There was one cervical laceration surgically repaired and a case of adnexitis reported among the hand syringe group. Immediate complications occurred in 7.3% of the cases using the hand syringe and in 4.1% of using the electric pump. The mean procedural time was 4.2 minutes and 4.0 minutes, respectively, with the hand syringe and the electric pump. Only three women reported complications or complaints at the follow-up visit, all of them from the electric pump group.

[Controlled vacuum extraction by measuring the pressure exercised by the truss (author's transl)].

The article explains a method for measuring the adhesivity between the anterior part of the foetus and the suction bulb of the vacuum extractor described by Malmström (1). The cover plate of the suction bulb, which is fitted with an expanding measuring strip, is used for reading off the measurements. This enables a quantitative recording of the pressure existing between the foetal part and the truss which corresponds very closely with the adhesivity of the suction bulb to the anterior part of the foetus. The device allows control and recording by means of an instrument with indicator and scale and a recording device. In this manner, vacuum extraction can be subjected to continuous control, thus rendering this obstetric procedure safer and easier.

[Is rotation in vacuum extraction possible?].

Vacuum extraction is a traction instrument and hardly suitable for accomplishing rotation. This assumption is disproved by means of two new suction cups that are being used in China. These suction cups and their use are described together with the relevant indication.

[Rarely occurring complications in vacuum extraction].

The authors report on two seldom observed complications of vacuum extraction, infraction or fracture of the parietal bone of newborn. They healed up without sequels in the further psychomotoric development. The authors consider vacuum extraction as a contribution to obstetric operation practise. They recommend smaller cups with a maximum diameter of 40 mm and a suction vacuum only to 0,6 kp/cm2 (0,06 M Pa) to be used.

[Labor in the older primipara].

In the Gynecology Department Split's General Medical hospital, during the period of 5 years (1975-1979) examinations were carried out on primiparas (10775 up to the age of 29, then 504 between the ages of 30-34, and 250 older then 35). These patients had pregnancy complications (EPH-gestosis and diabetes mellitus), premature delivery, birth of children with less then 2500 grams, overcarriage, obstetrical intervention (forceps, vacuum extraction, caesarian) section and perinal mortality and morbidity. Premature delivery and the birth of children lighter then 2500 grams is significantly increased between the ages of 30-34, and still increasing after the age of 35. The frequency of EPH--gestosis is increased between the ages of 30 and 34 and still increasing after the age of 35. The significant increase of diabetes in pregnancy becomes evident after the age of 35. Deliveries ended by an operation become very frequent between the ages of 30-34, significantly increasing after the age of 35 (vacuum extraction and caesarean). Perinal morbidity and mortality are significantly increased after the age of 35. The Author's conclusion is that older primiparas are those women who are expecting their first child after the age of 35. Primiparas between the ages of 30-34, because of the higher rate of fetal injury, should be shown more attention in the perinal period.

Instrumental (operative) vaginal deliveries: vacuum extraction compared with forceps delivery at Ilorin University Teaching Hospital, Nigeria.

In a four-year period (1984 to 1987) a total of 141 Nigerian women who had instrumental vaginal deliveries at term in the Obstetric unit of University of Ilorin Teaching Hospital, Ilorin, were studied. Out of this number 79 had forceps delivery while 62 had vacuum extraction. The forceps delivery rate had fluctuated between 0.11% and 0.46% while the vacuum extraction rate had steadily increased from 0.08% to 0.39% (Table 1) in our unit over the 4-year period. With the exception of fetal distress, there were no significant differences found in the indications for forceps delivery and vacuum extraction. The preapplication station, position and cervical dilatation differ in both groups (Table 4). There was less maternal trauma in vacuum extraction than forceps (Table 5). The vacuum extraction was more associated with cephalhaematoma and neonatal jaundice but less with neonatal mortality compared with forceps (Table 7). Vacuum extraction had gradually assumed more prominence as an alternative to midforceps delivery in our unit in the study period. There was no maternal mortality in the two groups.

[Surgical obstetrics in past and presence (author's transl)].

The history of surgical obstetrics is highlighted by discussing the historical development of forceps delivery, vacuum extraction, forceps vectis (application of a single blade only), embryotomy, and caesarean section operations. Finally present status of operative obstetrics is outlined from a modern point of view.

Forceps and vacuum injuries to the cornea: histopathologic features of twelve cases and review of the literature.

Histopathologic and ultrastructural features were examined from 11 cases of corneal injury from obstetrical forceps and one case from vacuum extraction. Four major types of histopathologic features were observed. Type I (n = 4) included large tears of Descemet's membrane with a fragment of Descemet's membrane extending into the anterior chamber at one end of the tear and scroll formation at the other end. Type II (n = 6) consisted of scrolls of Descemet's membrane at each margin of the original break. Type III (n = 2) included those with small breaks in Descemet's membrane and healing by fibrosis at and posterior to the original tear. Type IV (n = 1) contained a small break in Descemet's membrane with minimal fibrosis. Transmission electron microscopy revealed Descemet's scrolls and retrocorneal fibrous tissue. Scanning electron microscopy revealed folds in Descemet's membrane and attenuation or absence of endothelium. Spindle- and stellate-shaped cells and pigment granules were present in the area of the tear in most cases. A review of the literature is presented.

Long-term effects of vacuum and forceps deliveries.

The long-term effects of vacuum and forceps deliveries are largely unknown. We determined the long-term outcome of instrumental deliveries in 52,282 infants born in Jerusalem between 1964 and 1972. For each individual, events at birth were related to results of an intelligence test and medical examination done at 17 years of age by the Israeli Defence Forces draft board. 1747 individuals were delivered by vacuum, 937 by forceps, 47,500 by spontaneous delivery, and 2098 by caesarean section. Crude data showed that mean intelligence scores at 17 were significantly higher (p less than 0.0001) in the vacuum and forceps deliveries groups than in the spontaneous-delivery group; however, after adjustment for confounding factors by stepwise multiple regression, these differences were no longer seen. Although the forceps-delivery group had functional impairment of feet, vision, and retina compared with the spontaneous-delivery group, and the vacuum-extraction group had impairment of the legs, differences were small. Our findings suggest that infants delivered by vacuum or forceps are not at risk of physical and cognitive impairment at 17 years of age.
