Differences in management and results in term-delivery in nine European referral hospitals: descriptive study

Factors Associated with the Type of Cesarean Section in Greece and Their Correlation with International Guidelines

BACKGROUND

Cesarean section (CS) rates have been increasing worldwide with different effects on maternal and neonatal health. Factors responsible for the growing trend of CSs, include maternal characteristics, medical insurance and convenient scheduling or financial incentives. Effective interventions and guidelines are required to reduce CS rates.

OBJECTIVE

The aim of this research was to investigate the factors contributing to CS rate increase and their correlation with international guidelines.

METHODS

The performed analysis included the available socio-demographic and medical information retrieved from the medical records and a related questionnaire in both emergency and elective CSs.

RESULTS

Out of the included 633 births, the cesarean delivery rate was 58%. Women with a previous CS showed higher percentages for Elective CS (66.1%) compared to Emergency CSs for the same reasons (8.9%). Furthermore, 23% of the patients underwent an Emergency CS because of failure of labor to progress while 18% of CSs were due to maternal desire.

CONCLUSION

The high rates of CS in Greece demonstrate the lack of use of international obstetric protocols, national strategies, Cesarean Section audits and a significant shortage of midwives. A decrease in iatrogenic and non-iatrogenic factors leading to the primary CS will decrease CS rates.

Morphine acts on spinal dynorphin neurons to cause itch through disinhibition

Morphine-induced itch is a very common and debilitating side effect that occurs in laboring women who receive epidural analgesia and in patients who receive spinal morphine for relief of perioperative pain. Although antihistamines are still widely prescribed for the treatment of morphine-induced itch, their use is controversial because the cellular basis for morphine-induced itch remains unclear. Here, we used animal models and show that neuraxial morphine causes itch through neurons and not mast cells. In particular, we found that spinal dynorphin (Pdyn) neurons are both necessary and sufficient for morphine-induced itch in mice. Agonism of the kappa-opioid receptor alleviated morphine-induced itch in mice and nonhuman primates. Thus, our findings not only reveal that morphine causes itch through a mechanism of disinhibition but also challenge the long-standing use of antihistamines, thereby informing the treatment of millions worldwide.

Characterization of tissue properties in epidural needle insertion on human specimen and synthetic materials

The force experienced while inserting an 18-gauge Tuohy needle into the epidural space or dura is one of only two feedback components perceived by an anaesthesiologist to deduce the needle tip position in a patient's spine. To the best of the authors knowledge, no x-ray validated measurements of these forces are currently available to the public. A needle insertion force recording during an automated insertion of an 18-gauge Tuohy needle into human vertebral segments of four female donors was conducted. During the measurements, x-ray images were recorded simultaneously. The force peaks due to the penetration of the ligamentum supraspinale and ligamentum flavum were measured and compared to the measurements of an artificial patient phantom for a hybrid patient simulator. Based on these force peaks and the slope of the ligamentum interspinale, a mathematical model was developed. The model parameters were used to compare human specimens and artificial patient phantom haptics. The force peaks for the ligamenta supraspinale and flavum were 7.55 ± 3.63 N and 15.18 ± 5.71 N, respectively. No significant differences were found between the patient phantom and the human specimens for the force peaks and four of six physical model parameters. The patient phantom mimics the same resistive force against the insertion of an 18-gauge Tuohy needle. However, there was a highly significant (p < 0.001, eff_size = 0.949 and p < 0.001, eff_size = 0.896) statistical difference observed in the insertion depth where the force peaks of the ligamenta supraspinale and flavum were detected between the measurements on the human specimens and the patient phantom. Within this work, biomechanical evidence was identified for the needle insertion force into human specimens. The comparison of the measured values of the human vertebral segments and the artificial patient phantom showed promising results.

A novel approach to neuraxial anesthesia: application of an automated ultrasound spinal landmark identification

Background

Neuraxial procedures are commonly performed for therapeutic and diagnostic indications. Currently, they are typically performed via palpation-guided surface landmark. We devised a novel intelligent image processing system that identifies spinal landmarks using ultrasound images. Our primary aim was to evaluate the first attempt success rate of spinal anesthesia using landmarks obtained from the automated spinal landmark identification technique.

Methods

In this prospective cohort study, we recruited 100 patients who required spinal anesthesia for surgical procedures. The video from ultrasound scan image of the L3/4 interspinous space in the longitudinal view and the posterior complex in the transverse view were recorded. The demographic and clinical characteristics were collected and analyzed based on the success rates of the spinal insertion.

Results

Success rate (95%CI) for dural puncture at first attempt was 92.0% (85.0–95.9%). Median time to detection of posterior complex was 45.0 [IQR: 21.9, 77.3] secs. There is good correlation observed between the program-recorded depth and the clinician-measured depth to the posterior complex (r = 0.94).

Conclusions

The high success rate and short time taken to obtain the surface landmark with this novel automated ultrasound guided technique could be useful to clinicians to utilise ultrasound guided neuraxial techniques with confidence to identify the anatomical landmarks on the ultrasound scans. Future research would be to define the use in more complex patients during the administration of neuraxial blocks.

Trial registration

This study was retrospectively registered on clinicaltrials.gov registry (NCT03535155) on 24 May 2018.

Statistical trends of episiotomy around the world: Comparative systematic review of changing practices

The authors' purpose for this article is to identify, review and interpret all publications about the episiotomy rates worldwide. Based on the criteria from the PRISMA guidelines, twenty databases were scrutinized. All studies which include national statistics related to episiotomy were selected, as well as studies presenting estimated data. Sixty-one papers were selected with publication dates between 1995 and 2016. A static and dynamic analysis of all the results was carried out. The assumption for the decline in the number of episiotomies is discussed and confirmed, recalling that nowadays high rates of episiotomy remain in less industrialized countries and East Asia. Finally, our analysis aims to investigate the potential determinants which influence apparent statistical disparities.

Hospital variation in cost of childbirth and contributing factors: a cross-sectional study

OBJECTIVE

To examine hospital variation in cost of childbirth hospitalisations and identify factors that contribute to the variation.

DESIGN

Cross-sectional analysis of linked birth certificate and hospital discharge data.

SETTING

Two hundred and twenty hospitals in California delivering ≥ 100 births per year.

POPULATION

A total of 405 908 nulliparous term singleton vertex births during 2010-2012.

METHODS

Cost of childbirth hospitalisations was compared across hospitals after accounting for differences in patient clinical risk factors. Relative contributions of patient sociodemographic, obstetric intervention, birth attendant and institutional characteristics to variation in cost were assessed by further adjusting for these factors in hierarchical generalised linear models.

MAIN OUTCOME MEASURES

Cost of childbirth hospitalisation.

RESULTS

Median risk-standardised cost of childbirth was $7149 among the hospitals (10^th -90th percentile range: $4760-$10,644). Maternal sociodemographic characteristics and type of birth attendant did not explain hospital variation in cost. Adjustment for obstetric interventions overall reduced within-hospital variance by 15.8% (P < 0.001), while adjusting for caesarean delivery alone reduced within-hospital variance by 14.4% (P < 0.001). However, obstetric interventions did not explain between-hospital variation in cost. In contrast, adjustment for institutional characteristics reduced between-hospital variance by 30.3% (P = 0.002). Hospital type of ownership, teaching/urban-rural status, neonatal care capacity and geographic region were most impactful. Risk-standardised cost was positively correlated with risk-standardised rate of severe newborn morbidities (correlation coefficient 0.22, P = 0.001), but not associated with risk-standardised rate of severe maternal morbidities.

CONCLUSIONS

Cost of childbirth hospitalisations varied widely among hospitals in California. Institutional characteristics significantly contributed to this variation. Higher-cost hospitals did not have better outcomes, suggesting potential opportunities to enhance value in care.

TWEETABLE ABSTRACT

Hospitals vary in cost of childbirth. Institutional characteristics significantly contribute to the variation.

Development of artificial tissue-like structures for a hybrid epidural anesthesia simulator

Puncturing the epidural space and lumbar puncture are common procedures in anesthesia. They are carried out blind, where a needle is advanced from posterior between two adjacent vertebrae. Two different approaches are common practice for this technique, the midline and the paramedian one. The learning curve characteristics of both approaches significantly depends on the number of punctures carried out by a medical novice. For the training of these blind procedures a hybrid simulator requires artificial structures imitating the tissues which are penetrated by the needle. Within this work a patient phantom for spinal needle insertion procedures was developed and validated successfully against literature as well as by a study carried out with medical experts.

Fundal pressure during the second stage of labour

BACKGROUND

Fundal pressure during the second stage of labour (also known as the 'Kristeller manoeuvre') involves application of manual pressure to the uppermost part of the uterus directed towards the birth canal, in an attempt to assist spontaneous vaginal birth and avoid prolonged second stage or the need for operative birth. Fundal pressure has also been applied using an inflatable belt. Fundal pressure is widely used, however methods of its use vary widely. Despite strongly held opinions in favour of and against the use of fundal pressure, there is limited evidence regarding its maternal and neonatal benefits and harms. There is a need for objective evaluation of the effectiveness and safety of fundal pressure in the second stage of labour.

OBJECTIVES

To determine if fundal pressure is effective in achieving spontaneous vaginal birth, and preventing prolonged second stage or the need for operative birth, and to explore maternal and neonatal adverse effects related to fundal pressure.

SEARCH METHODS

We searched Cochrane Pregnancy and Childbirth's Trials Register (30 November 2016) and reference lists of retrieved studies.

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials of fundal pressure (manual or by inflatable belt) versus no fundal pressure in women in the second stage of labour with singleton cephalic presentation.

DATA COLLECTION AND ANALYSIS

Two or more review authors independently assessed potential studies for inclusion and quality. We extracted data using a pre-designed form. We entered data into Review Manager 5 software and checked for accuracy.

MAIN RESULTS

Nine trials are included in this updated review. Five trials (3057 women) compared manual fundal pressure versus no fundal pressure. Four trials (891 women) compared fundal pressure by means of an inflatable belt versus no fundal pressure. It was not possible to blind women and staff to this intervention. We assessed two trials as being at high risk of attrition bias and another at high risk of reporting bias. All other trials were low or unclear for other risk of bias domains. Most of the trials had design limitations. Heterogeneity was high for the majority of outcomes. Manual fundal pressure versus no fundal pressureManual fundal pressure was not associated with changes in: spontaneous vaginal birth within a specified time (risk ratio (RR) 0.96, 95% confidence interval (CI) 0.71 to 1.28; 120 women; 1 trial; very low-quality evidence), instrumental births (RR 3.28, 95% CI 0.14 to 79.65; 197 women; 1 trial), caesarean births (RR 1.10, 95% CI 0.07 to 17.27; 197 women; 1 trial), operative birth (average RR 0.66, 95% CI 0.12 to 3.55; 317 women; 2 studies; I² = 43%; Tau² = 0.71; very low-quality evidence), duration of second stage (mean difference (MD) -0.80 minutes, 95% CI -3.66 to 2.06 minutes; 194 women; 1 study; very low-quality evidence), low arterial cord pH in newborn babies (RR 1.07, 95% CI 0.72 to 1.58; 297 women; 2 trials; very low-quality evidence), or Apgar scores less than seven at five minutes (average RR 4.48, 95% CI 0.28 to 71.45; 2759 infants; 4 trials; I² = 89%; Tau² = 3.55; very low-quality evidence). More women who received manual fundal pressure had cervical tears than in the control group (RR 4.90, 95% CI 1.09 to 21.98; 295 women; 1 trial). No neonatal deaths occurred in either of the two studies reporting this outcome (very low-quality evidence). No trial reported the outcome severe maternal morbidity or death. Fundal pressure by inflatable belt versus no fundal pressureFundal pressure by inflatable belt did not reduce the number of women havinginstrumental births (average RR 0.73, 95% CI 0.52 to 1.02; 891 women; 4 trials; I² = 52%; Tau² = 0.05) or operative births (average RR 0.62, 95% CI 0.38 to 1.01; 891 women; 4 trials; I² = 78%; Tau² = 0.14; very low-quality evidence). Heterogeneity was high for both outcomes. Duration of second stage was reported in two trials, which both showed that inflatable belts shortened duration of labour in nulliparous women (average MD -50.80 minutes, 95% CI -94.85 to -6.74 minutes; 253 women; 2 trials; I² = 97%; Tau² = 975.94; very low-quality evidence). No data on this outcome were available for multiparous women. The inflatable belt did not make any difference to rates of caesarean births (average RR 0.56, 95% CI 0.14 to 2.26; 891 women; 4 trials; I² = 70%; Tau² = 0.98), low arterial cord pH in newborn babies (RR 0.47, 95% CI 0.09 to 2.55; 461 infants; 1 trial; low-quality evidence), or Apgar scores less than seven at five minutes (RR 4.62, 95% CI 0.22 to 95.68; 500 infants; 1 trial; very low-quality evidence). Third degree perineal tears were increased in the inflatable belt group (RR 15.69, 95% CI 2.10 to 117.02; 500 women; 1 trial). Spontaneous vaginal birth within a specified time, neonatal death, andsevere maternal morbidity or death were not reported in any trial.

AUTHORS' CONCLUSIONS

There is insufficient evidence to draw conclusions on the beneficial or harmful effects of fundal pressure, either manually or by inflatable belt. Fundal pressure by an inflatable belt during the second stage of labour may shorten duration of second stage for nulliparous women, and lower rates of operative birth. However, existing studies are small and their generalizability is uncertain. There is insufficient evidence regarding safety for the baby. There is no evidence on the use of fundal pressure in specific clinical settings such as inability of the mother to bear down due to exhaustion or unconsciousness. There is currently insufficient evidence for the routine use of fundal pressure by any method on women in the second stage of labour. Because of current widespread use of the procedure and the potential for use in settings where other methods of assisted birth are not available, further good quality trials are needed. Further evaluation in other groups of women (such as multiparous women) will also be required. Future research should describe in detail how fundal pressure was applied and consider safety of the unborn baby, perineal outcomes, longer-term maternal and infant outcomes and maternal satisfaction.

[The practice of episiotomy in France 10 years after the recommendations of CNGOF: What inventory?]

Since its creation, the practice of episiotomy has evolved, being influenced by several factors. Various stances on its use were stated, until the eventual reduction of this practice, as suggested by numerous practical guides. In 2005, the National College of Obstetricians and Gynecologists in France published its French Guidelines for Clinical practice in this area. Today, it seems appropriate to focus on the evolution of the use of episiotomy, ten years after the publication of these recommendations. The authors propose a literature review, browsing through all the available epidemiological data in France related to episiotomy, recording all national statistics and some local trends, as there are regional specificities. This review allows to follow the overall evolution of the practice of episiotomy in France between 1981 and 2014, and to identify territorial disparities. Finally, in the specific context of the practice of episiotomy in French gynecological and obstetrics field, the authors conclude it by considering the possible evolution of this surgical practice, as well as, the Clinical Practice Recommendations related to it.

Early versus late initiation of epidural analgesia for labour

BACKGROUND

Pain during childbirth is arguably the most severe pain some women may experience in their lifetime. Epidural analgesia is an effective form of pain relief during labour. Many women have concerns regarding its safety. Furthermore, epidural services and anaesthetic support may not be available consistently across all centres. Observational data suggest that early initiation of epidural may be associated with an increased risk of caesarean section, but the same findings were not seen in recent randomised controlled trials. More recent guidelines suggest that in the absence of a medical contraindication, maternal request is a sufficient medical indication for pain relief during labour. The choice of analgesic technique, agent, and dosage is based on many factors, including patient preference, medical status, and contraindications. There is no systematically reviewed evidence on the maternal and foetal outcomes and safety of this practice.

OBJECTIVES

This systematic review aimed to summarise the effectiveness and safety of early initiation versus late initiation of epidural analgesia in women. We considered the obstetric and fetal outcomes relevant to women and side effects of the treatments, including risk of caesarean section, instrumental birth and time to birth.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (12 February 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 1), MEDLINE (January 1966 to February 2014), Embase (January 1980 to February 2014) and reference lists of retrieved studies.

SELECTION CRITERIA

We included all randomised controlled trials involving women undergoing epidural labour analgesia that compared early initiation versus late initiation of epidural labour analgesia.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion, extracted the data and assessed the trial quality. Data were checked for accuracy.

MAIN RESULTS

We included nine studies with a total of 15,752 women.The overall risk of bias of the studies was low, with the exception of performance bias (blinding of participants and personnel).The nine studies showed no clinically meaningful difference in risk of caesarean section with early initiation versus late initiation of epidural analgesia for labour (risk ratio (RR) 1.02; 95% confidence interval (CI) 0.96 to 1.08, nine studies, 15,499 women, high quality evidence). There was no clinically meaningful difference in risk of instrumental birth with early initiation versus late initiation of epidural analgesia for labour (RR 0.93; 95% CI 0.86 to 1.01, eight studies, 15,379 women, high quality evidence). The duration of second stage of labour showed no clinically meaningful difference between early initiation and late initiation of epidural analgesia (mean difference (MD) -3.22 minutes; 95% CI -6.71 to 0.27, eight studies, 14,982 women, high quality evidence). There was significant heterogeneity in the duration of first stage of labour and the data were not pooled.There was no clinically meaningful difference in Apgar scores less than seven at one minute (RR 0.96; 95% CI 0.84 to 1.10, seven studies, 14,924 women, high quality evidence). There was no clinically meaningful difference in Apgar scores less than seven at five minutes (RR 0.96; 95% CI 0.69 to 1.33, seven studies, 14,924 women, high quality evidence). There was no clinically meaningful difference in umbilical arterial pH between early initiation and late initiation (MD 0.01; 95% CI -0.01 to 0.03, four studies, 14,004 women, high quality evidence). There was no clinically meaningful difference in umbilical venous pH favouring early initiation (MD 0.01; 95% CI -0.00 to 0.02, four studies, 14,004 women, moderate quality evidence).

AUTHORS' CONCLUSIONS

There is predominantly high-quality evidence that early or late initiation of epidural analgesia for labour have similar effects on all measured outcomes. However, various forms of alternative pain relief were given to women who were allocated to delayed epidurals to cover that period of delay, so that is it hard to assess the outcomes clearly. We conclude that for first time mothers in labour who request epidurals for pain relief, it would appear that the time to initiate epidural analgesia is dependent upon women's requests.

Fundal pressure during the second stage of labor in a tertiary obstetric center: a prospective analysis

AIM

To ascertain whether uterine fundal pressure should have a role in the management of the second stage of labor and to determine its prevalence, benefits and adverse maternal-fetal outcomes.

METHODS

This was a prospective observational study set in a tertiary teaching and research obstetric hospital. A total of 8097 women in labor between 37 and 42 gestational weeks with a singleton cephalic presentation were enrolled. Subjects were subdivided into two groups: fundal pressure group (n=1974 women) and control group (n=6123 women). The primary outcome measure was the duration of the second stage. The secondary outcome measures were maternal outcomes (immediate or delayed) and neonatal outcomes.

RESULTS

The prevalence of fundal pressure in our center was 24.38%. Fundal pressure maneuver significantly shortened the duration of the second stage among primiparous women, increased the risk of severe perineal laceration and admission to neonatal intensive care unit in comparison to the non-fundal group. Delayed maternal outcomes showed significant increase in dyspareunia and de novo stress urinary incontinence in the fundal pressure group.

CONCLUSION

Although fundal pressure maneuver shortens the duration of the second stage of labor among primiparous women, it should not be used except when indicated, and under strict guidelines owing to its adverse maternal and fetal outcomes.

[Obstetric anesthesia in Catalonia, Spain]

BACKGROUND AND OBJECTIVE

The aim of this arm of the ANESCAT 2003 study was to describe obstetric anesthesia and analgesia practice in Catalonia, Spain.

PATIENTS AND METHOD

Using information obtained from a survey of anesthesia performed in Catalonia in 2003, data was identified on anesthesia for obstetric procedures: labor, cesarean section, and others unrelated to childbirth. Patient characteristics were analyzed along with anesthetic techniques and the rates at which they are used in the population.

RESULTS

Obstetric procedures were performed in 71 hospitals (54% of the hospitals surveyed). Obstetric anesthesia represented 11.3% of total anesthesia practice, corresponding to an estimated 67,864 anesthetic procedures per year. Of those procedures, 87.7% were associated with labor and childbirth. An estimated 82% of the 71,851 births in Catalonia were assisted by an anesthesiologist. Cesarean sections accounted for 25.1% of births and the rate increased with age. Regional anesthesia for labor and cesarean section was used in 98.7% and 96.2% of cases, respectively. Epidural anesthesia was used in 96.9% of vaginal births. In elective and emergency cesarean sections, spinal block was used in 75.5% and 44.8% of cases, respectively, while epidural anesthesia was used in 23.3% and 53.3%, respectively.

CONCLUSIONS

The anesthesia coverage for labor in Catalonia is the highest published. The use of regional anesthetic techniques in Catalonia is also the highest recorded. Although continuous epidural anesthesia is the most widely used technique, spinal block is also increasingly employed.

Fundal pressure during the second stage of labour

BACKGROUND

Fundal pressure during the second stage of labour involves application of manual pressure to the uppermost part of the uterus directed towards the birth canal in an attempt to assist spontaneous vaginal delivery and avoid prolonged second stage or the need for operative delivery. Fundal pressure has also been applied using an inflatable girdle. A survey in the United States found that 84% of the respondents used fundal pressure in their obstetric centres.There is little evidence to demonstrate that the use of fundal pressure is effective to improve maternal and/or neonatal outcomes. Several anecdotal reports suggest that fundal pressure is associated with maternal and neonatal complications: for example, uterine rupture, neonatal fractures and brain damage. There is a need for objective evaluation of the effectiveness and safety of fundal pressure in the second stage of labour.

OBJECTIVES

To determine the benefits and adverse effects of fundal pressure in the second stage of labour.

SEARCH STRATEGY

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (November 2008).

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials of fundal pressure versus no fundal pressure in women in the second stage of labour with singleton cephalic presentation.

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed for inclusion all the potential studies. We extracted the data using a pre-designed form. We entered data into Review Manager software and checked for accuracy.

MAIN RESULTS

We excluded two of three identified trials from the analyses for methodological reasons. This left no studies on manual fundal pressure. We included one study (500 women) of fundal pressure by means of an inflatable belt versus no fundal pressure to reduce operative delivery rates. The methodological quality of the included study was good.Use of the inflatable belt did not change the rate of operative deliveries (RR 0.94, 95% CI 0.80 to 1.11). Fetal outcomes in terms of five-minute Apgar scores below seven (RR 4.62, 95% CI 0.22 to 95.68), low arterial cord pH (RR 0.47, 95% CI 0.09 to 2.55) and admission to the neonatal unit (RR 1.48, 95% CI 0.49 to 4.45) were also not different between the groups. There was no severe neonatal or maternal mortality or morbidity. There was an increase in intact perineum (RR 1.73, 95% CI 1.07 to 2.77), as well as anal sphincter tears (RR 15.69, 95% CI 2.10 to 117.02) in the belt group. There were no data on long-term outcomes.

AUTHORS' CONCLUSIONS

There is no evidence available to conclude on beneficial or harmful effects of manual fundal pressure. Good quality randomised controlled trials are needed to study the effect of manual fundal pressure. Fundal pressure by an insufflatable belt during the second stage of labour does not appear to increase the rate of spontaneous vaginal births in women with epidural analgesia. There is insufficient evidence regarding safety for the baby. The effects on the maternal perineum are inconclusive.

[Pelvic floor disorders four years after first delivery: a comparative study of restrictive versus systematic episiotomy]

OBJECTIVE

To compare two policies for episiotomy: restrictive and systematic.

PATIENTS AND METHODS

It is a quasi-randomised comparative study between two French university hospitals with contrasting episiotomy policies: one using it restrictively and the second routinely. Population included 774 nulliparous women delivered during 1996 of a singleton in cephalic presentation at a term of 37-41 weeks. A questionnaire was mailed four years after delivery. Sample size was calculated to allow showing a 10% difference in the prevalence of urinary incontinence with 80% power. Main outcome measures were urinary incontinence, anal incontinence, perineal pain and pain during intercourse.

RESULTS

We received 627 responses (81%), 320 from women delivered under the restrictive policy, 307 from women delivered under the routine policy. In the restrictive group, 186 (49%) deliveries included mediolateral episiotomies and in the routine group, 348 (88%). Four years after the first delivery, the groups did not differ in the prevalence of urinary incontinence (26% versus 32%), perineal pain (6% versus 8%), or pain during intercourse (18% versus 21%). Anal incontinence was less prevalent in the restrictive group (11% versus 16%). The difference was significant for flatus (8% versus 13%) but not for faecal incontinence (3% for both groups). Logistic regression confirmed that a policy of routine episiotomy was associated with a risk of anal incontinence nearly twice as high as the risk associated with a restrictive policy (OR=1.84, 95 % CI :1.05-3.22).

DISCUSSION AND CONCLUSION

A policy of routine episiotomy does not protect against urinary or anal incontinence four years after first delivery.

Possible feto-maternal clinical risk of the Kristeller’s expression

The aim of this clinical case study is evaluation of possible intrapartal complication of the uncritical Kristeller’s expression. In this retrospective clinical study, data on seven parturients with significant maternal or fetal intrapartum complications during the second labor stage and Kristeller expression, associated with the maneuver, were analyzed. Data was obtained from patient files: history of delivery delivery room protocol and neonatal reports from two tertiary maternal wards. There were five uterine ruptures that were treated by laparotomy and uterine sutures. Atypical rupture location on the uterine fundus occurred in one case, isthmus rupture in three cases, and rupture of the scar left after a previous cesarean section as a potential risk factor for uterine rupture in one case. Complex uterine cervicoisthmic rupture with incomplete colporrhexis occurred during the delivery of a macrosomic child at an outpatient ward. In one case, unilateral fracture of the tenth and eleventh ribs resolved spontaneously without complications. One case of peripartum trauma, possibly associated with extensive expression was observed in one neonates: cutaneous and subcutaneous hematoma on the back with traumatic unilateral adrenal hemorrhage. Both newborns were monitored, successfully treated, and discharged from the hospital free from complications. In conclusion, in the obstetrics as a high risk profession, a very critical approach should be exercised on choosing this maneuver, which should be reserved for the rare and strictly indicated cases, thereby strictly following the professional rules to avoid generally unnecessary and unpleasant litigation and forensic expertise.

Pelvic floor disorders 4 years after first delivery: a comparative study of restrictive versus systematic episiotomy

OBJECTIVE

To compare two policies for episiotomy: restrictive and systematic.

DESIGN

Quasi-randomised comparative study.

SETTING

Two French university hospitals with contrasting policies for episiotomy: one using episiotomy restrictively and the second routinely.

POPULATION

Seven hundred and seventy-four nulliparous women delivered during 1996 of a singleton in cephalic presentation at a term of 37-41 weeks.

METHODS

A questionnaire was mailed 4 years after delivery. Sample size was calculated to allow us to show a 10% difference in the prevalence of urinary incontinence with 80% power.

MAIN OUTCOME MEASURES

Urinary incontinence, anal incontinence, perineal pain, and pain during intercourse.

RESULTS

We received 627 responses (81%), 320 from women delivered under the restrictive policy, 307 from women delivered under the routine policy. In the restrictive group, 186 (49%) deliveries included mediolateral episiotomies and in the routine group, 348 (88%). Four years after the first delivery, there was no difference in the prevalence of urinary incontinence (26 versus 32%), perineal pain (6 versus 8%), or pain during intercourse (18 versus 21%) between the two groups. Anal incontinence was less prevalent in the restrictive group (11 versus 16%). The difference was significant for flatus (8 versus 13%) but not for faecal incontinence (3% for both groups). Logistic regression confirmed that a policy of routine episiotomy was associated with a risk of anal incontinence nearly twice as high as the risk associated with a restrictive policy (OR = 1.84, 95% CI: 1.05-3.22).

CONCLUSIONS

A policy of routine episiotomy does not protect against urinary or anal incontinence 4 years after first delivery.

Variation in rates of postterm birth in Europe: reality or artefact?

OBJECTIVE

To compare rates of postterm birth in Europe.

DESIGN

Analysis of data from vital statistics, birth registers, and national birth samples collected for the PERISTAT project.

SETTING

Thirteen European countries.

POPULATION

All live births or representative samples of births for the year 2000 or most recent year available.

METHODS

Comparison of national and regional rates of postterm birth. Other indicators (birthweight, deliveries with a non-spontaneous onset and mortality) were used to assess the validity of postterm rates.

MAIN OUTCOME MEASURES

The proportion of births at 42 completed weeks of gestation or later.

RESULTS

Postterm rates varied greatly, from 0.4% (Austria, Belgium) to over 7% (Denmark, Sweden) of births. Higher postterm rates were associated with a greater proportion of babies with birthweight 4500 g or more. Fetal and early neonatal mortality rates were higher among postterm births than among births at 40 weeks. Countries with higher proportions of births with a nonspontaneous onset of labour had lower postterm birth rates. The shapes of the gestational-age distributions at term varied. In some countries, there was a sharp cutoff in deliveries at 40 weeks, while elsewhere this occurred at 41 weeks.

CONCLUSIONS

These results suggest that practices for managing pregnancies continuing beyond term differ in Europe and raise questions about the health and other impacts in countries with markedly high or low postterm rates. Some variability in these rates may also be due to methods for determining gestational age, which has broader implications for international comparisons of gestational age, including rates of postterm and preterm births and small-for-gestational-age newborns.

Demande d'analgésie périmédullaire par les patientes et les équipes obstétricales dans quatre régions françaises. Partie II : réalisation des analgésies périmédullaires

OBJECTIVE

Epidural analgesia (EA) is widely used in France to treat the labour pain. The aim of this study was to evaluate and analyse the rate of EA and the ratio between EA required by parturients and total EA realised (performance ratio).

STUDY DESIGN

An epidemiological survey was sent in all maternity units of 4 French areas. Patients and methods. - 48 of the 84 maternity units were participating to the study. In each centre, 25 patients fulfilled the questionnaire and the medical team fulfilled a questionnaire about the organisation of the ward. Rate of EA and performance ratio were calculated. Student t test, chi2 test and logistic regression model were used as requested; p<0.05 was considered as significant.

RESULTS

The mean rate of epidural analgesia (EA) rate, in the French areas studied, was 61.6%. It was significantly higher in university (79+/-13.7%) and private hospital (73.1+/-20.4%) than in general hospitals (54.6+/-19.6%, p<0.01), and also in those where anaesthesiologists are dedicated to the maternity unit (71.3+/-17.8 vs 54.6+/-22.1%, p<0.01) and in hospitals where anaesthesiologists were on duty in the hospital versus on call at home (69.8+/-21.4 vs 56.1+/-19%, p<0.02). Median duration of EA was 180 minutes, and 21.3% of them lasted more than five hours. Most of EA was performed between 8 AM and 6 PM. Patients' request was the major reason of EA insertion (OR=11.81), then the midwife request (OR=9.01). Other significant factors were the type of the hospital, the anaesthesiologist on duty and parity of women. The ratio between the number of EA requested by parturients and the total number of EA performed was significantly better in university hospitals (100.3+/-13%) and private hospitals (92.2+/-15.7%) than in general hospitals (79.4+/-17.3%, p<0.02). For the patients who had requested EA and did not have EA, the main reason was that labour was too fast (122/167) and then that there was a fail in anaesthesiological organization (59/167). The contraindications were rare (14/167).

CONCLUSION

To correctly answer to the request of EA, it seems necessary that one or more anaesthesiologists were dedicated to the maternity units, and that they were on duty into the hospital. So it seems important to have large maternities with adequate number of anaesthesiologists.

Analysing the Greek health system: a tale of fragmentation and inertia

The Greek health system does not yet offer universal coverage and has fragmented funding and delivery. Funding is regressive, with a reliance on informal payments, and there are inequities in access, supply and quality of services. Inefficiencies arise from an over reliance on relatively expensive inputs, as evidenced by the oversupply of specialists and under-supply of nurses. Resource allocation mechanisms are historical and political with no relation to performance or output, therefore providers have little incentive to improve productivity. Some options for future health system reform include focusing on coordinating funding by developing a monopsony purchaser with the aim of improving quality of services and efficiency in the health system and changing provider incentives to improve productivity.

Episiotomy rates around the world: an update

Episiotomy, the unkindest cut of all, persists despite clinical practice guidelines recommending its restrictive use. The purpose of this paper was to compile international statistics on the use of this practice and examine whether current guidance on the restrictive use of episiotomy was being followed.

METHODS

We searched government websites and the Internet, contacted colleagues for references, and checked the references of retrieved citations.

RESULTS

Statistics from around the world revealed overall high rates of episiotomy with a decreasing trend in some countries. Considerable variation occurs in the use of the operation by country, within countries, and even within the same professional provider group.

CONCLUSIONS

Greater efforts are needed than currently in place to reduce the episiotomy rate, particularly in the developing world.

Analgesia and Anesthesia in Labor

Whether given as an epidural, spinal, or combination, regional anesthesia is an integral part of obstetrics in the United States. A variety of drugs and dosages are used in various combinations, with no one protocol exceeding others in terms of efficacy and safety. The availability of anesthesia and analgesia has had an extraordinary impact on the field of obstetrics in the twentieth century. Knowledge of the techniques and medications used, their potential toxicities, and effects on the labor process itself can only enhance obstetricians' management of the parturient in labor.

Experience of pain and analgesia with water and land births

Labor is one of the most painful experiences in a woman's life. Does water birth influence the pain experienced? Data from an ongoing, longitudinal, prospective observational study that spans 9 years and includes questionnaires from 12,040 births were used to evaluate pain perception (visual analogue scale (VAS)) and analgesic use. Three birthing methods were compared: water birth, bed birth and Maia stool birth. Based on the VAS, the data show that the different birthing methods do not influence the intensity of pain throughout the different stages of labor. The only significant difference noted was that bed births are more painful in the early first stage, and less painful at the end of the second stage. This later difference may be due to increased use of epidural anesthesia in women choosing a bed birth. Women who choose bed births are significantly less likely than others to have an analgesic-free birth. For primiparas, there is also a small but significant difference showing that water births are less likely to require analgesics compared to Maia stool births. No such difference is seen in women who have given birth previously. We conclude that women who choose bed births perceive more pain in the early first stage of labor, leading them to be more likely to choose an epidural anesthesia in the late first stage, or to use other types of analgesics. Women who choose water births or Maia stool births are more likely to get through labor without using any analgesics.

An investigation of Caesarean sections in three Greek hospitals: the impact of financial incentives and convenience

BACKGROUND

Caesarean section (CS) rates have been increasing dramatically in the past decades around the world. The objective of our study was to investigate the factors increasing the likelihood of undergoing CS in two public hospitals and one private hospital in Athens, Greece. Specifically, the purpose was primarily to assess the impact of non-medical factors such as private health insurance, potential for making informal payments, physician convenience and socio-economic status on the rate of CS deliveries.

METHODS

All available demographic, socio-economic and medical information from the medical records of all deliveries in the three hospitals in January 2002 were analysed. The relative importance of the variables in predicting delivery with CS rather than normal vaginal delivery was calculated in multiple logistic regression models to generate odds ratios (OR).

RESULTS

The CS rate in the public hospitals was 41.6% (52.5% for Greeks and 26% for immigrants), while the CS rate in the private hospital was 53% (65.2% for women with private insurance and 23.9% for women who paid directly). In the public hospitals, after controlling for demographic and medical factors, Greek ethnic background, delivery between 8 a.m. and 4 p.m., between 4 p.m. and midnight, and on Monday, Wednesday and Friday were found to increase the likelihood of CS delivery. In the private hospital, having private health insurance is the strongest predictor of CS delivery, followed by delivery between 8 a.m. and 4 p.m., between 4 p.m. and midnight, delivery on a Saturday and being a housewife.

CONCLUSION

The results of this study lend support to the hypothesis that physicians are motivated to perform CS for financial and convenience incentives. The recent commercialization of gynaecology services in Greece is discussed, along with its implications on physicians' decisions to perform CS.

Breech vaginal delivery at or near term

Three percent to 4% of term fetuses will be breech at delivery. Evidence from randomized controlled trials has found a policy of planned cesarean section to be significantly better for the singleton fetus in breech presentation at term compared to a policy of planned vaginal birth. However, some women may wish to avoid cesarean section and for others, cesarean section may not be possible. We undertook this review to identify factors associated with higher and lower risk of adverse fetal or neonatal outcome at term during vaginal breech delivery. We searched MEDLINE from 1966 to 2002 using the search terms vaginal breech delivery and breech presentation and retrieved all relevant articles. We also reviewed personal references and reference lists of articles retrieved. Women who are older or who have a fetus that is either in footling presentation, has a hyperextended head or is estimated to weigh <2500 g or >4000 g may be at higher risk of adverse fetal outcome. Prolonged labor or not having an experienced clinician at vaginal breech birth may also increase the risk. Women with a fetus in breech presentation at term should be offered the option of delivery by planned cesarean section and should be informed that this will reduce their risk of adverse fetal or neonatal outcome. Practitioners should develop and maintain skills at vaginal breech delivery for those women not wishing or not able to be delivered by cesarean section.
