[Thierry's spatula instrumental extraction: a study of foetal-maternal morbidity].

OBJECTIVE: Assisted delivery is necessary in many obstetrical conditions but is involved in maternal and foetal complications. The legal pressure and the commendable aim consisting in less neonatal morbidity and mortality have called forth a reflection about the type and the way of instrumental foetal extraction. In 1950, Thierry had already felt this problem and he invented spatula to replace obstetrical forceps. Although this instrument appears empirically little deleterious, literature about its evaluation is very poor. We studied this instrument in a retrospective 190 cases series. PATIENTS AND METHOD: Retrospective study of 190 Thierry's spatula extractions, over a seven-year period (January 1996 to December 2002), at the Centre Hospitalier General of Montbeliard. RESULTS: Out of a total of 8126 deliveries for the study period, the instrumental extraction rate was 5.3%, with 40.6% spatula extractions (190 cases). No failure of Thierry's spatula extraction was noted. DISCUSSION ET CONCLUSION: Our study concludes that spatula is efficient but does not usually permit anterior rotation of occipito-posterior presentation. Maternal and foetal morbidity is not frequent.

[Løvseth's manoeuvre in breech presentation--"best and safest"].

During the first half of 20th century, the most important goal in obstetrics was to make vaginal deliveries safer. Two Norwegian gynaecologists put their mark on this development: Christian Kielland's (1871-1941) obstetric forceps and Jørgen Løvset's (1896-1981) manoeuvre in breech presentation. Løvset made several other contributions to Norwegian and international obstetrics, in particular a series of innovations. In his old age he advocated obstetrics as a form of art and underlined the importance of learning "what is necessary to be worthy of the name of obstetrician". He experienced the dramatic change in attitude to and frequency of caesarean section.

Preventing perineal trauma during childbirth: a systematic review.

OBJECTIVE: To review systematically techniques proposed to prevent perineal trauma during childbirth and meta-analyze the evidence of their efficacy from randomized controlled trials. DATA SOURCES: MEDLINE (1966-1999), the Cochrane Library (1999 Issue 1), and the Cochrane Collaboration: Pregnancy and Childbirth Database (1995); and reference lists from articles identified. Search terms included childbirth or pregnancy or delivery, and perineum, episiotomy, perineal massage, obstetric forceps, vacuum extraction, labor stage-second. No language or study-type constraints were imposed. STUDY SELECTION: Randomized controlled trials (RCTs) of interventions affecting perineal trauma were reviewed. If no RCTs were available, nonrandomized research designs such as cohort studies were included. Studies were selected by examination of titles and abstracts of more than 1,500 articles, followed by analysis of the methods sections of studies that appeared to be RCTs. INTEGRATION AND RESULTS: Eligible studies used random or quasirandom allocation of an intervention of interest and reported perineal outcomes. Further exclusions were based on failure to report results by intention to treat, or incomplete or internally inconsistent reporting of perineal outcomes. Final selection of studies and data extraction was by consensus of the first two authors. Data from trials that evaluated similar interventions were combined using a random effects model to determine weighted estimate of risk difference and number needed to treat. Effects of sensitivity analysis and quality scoring were examined. Results indicated good evidence that avoiding episiotomy decreased perineal trauma (absolute risk difference -0.23, 95% confidence interval [CI] -0.35, -0.11). In nulliparas, perineal massage during the weeks before giving birth also protected against perineal trauma (risk difference -0.08, CI -0.12, -0.04). Vacuum extraction (risk difference -0.06, CI -0.10, -0.02) and spontaneous birth (-0.11, 95% CI -0.18, -0.04) caused less anal sphincter trauma than forceps delivery. The mother's position during the second stage has little influence on perineal trauma (supported upright versus recumbent: risk difference 0.02, 95% CI -0.05, 0.09). CONCLUSION: Factors shown to increase perineal integrity include avoiding episiotomy, spontaneous or vacuum-assisted rather than forceps birth, and in nulliparas, perineal massage during the weeks before childbirth. Second-stage position has little effect. Further information on techniques to protect the perineum during spontaneous delivery is sorely needed.

Preliminary report: a clinical appraisal of the McGoldrick rotational vacuum extractor.

The results of a preliminary clinical appraisal of a newly designed vacuum extractor - the McGoldrick rotational vacuum extracter is presented. This instrument is designed to combine the rotation advantages of the various rotating obstetric forceps with the multiple advantages of the conventional vacuum extractor in the management of persistent occipito posterior and occipito transverse positions. The design features include an elliptical shaped cup attached to a series of bars and universal joints which allow both rotational and traction forces to be applied to the foetal scalp.

[Characteristics of uterine contraction and stages of labor under continuous epidural block anesthesia].

OBJECTIVE: To observe the characteristics of uterine contraction and stages of labor during delivery under continuous epidural block anesthesia. METHODS: Totaling 213 parturients in spontaneous labor under epidural block anesthesia with dilated cervical orifice of 3 cm were monitored for the contraction cycle, duration, intensity and curve types of uterine contraction, and recordings were made for 30 min before and 30, 60 and 120 min after the anesthesia took effect, respectively. The duration of the active phase in the first, second and third stages of labor was compared between 421 cases with anesthesia and 237 without anesthesia. RESULTS: Significant difference was noted in the objective indexes of uterine contraction recorded after anesthesia had taken effect (P<0.05) in comparison with those before anesthesia, suggesting significantly attenuated uterine contraction after anesthesia, whereas these indexes underwent no significant further variation as compared between different time points after anesthesia (P>0.05). The average active phase in the first stage was significantly shorter in anesthesia group than that in the control group (P<0.05), but the average duration of the second and third stages of labor differed little between the two groups with appropriate use of oxytocin under strict monitoring (P>0.05). The rates of obstetric forceps utilization and use of oxytocin were higher in anesthesia group than in the control group (P<0.05). CONCLUSION: Epidural block anesthesia produces certain influences on uterine contraction and stages of labor during delivery, for which appropriate treatment measures may prove beneficial.
