An observational study of the success and complications of 2546 external cephalic versions in low-risk pregnant women performed by trained midwives.

OBJECTIVE: To evaluate the success of an external cephalic version (ECV) training programme, and to determine the rates of successful ECV, complications, and caesarean birth in a low-risk population. DESIGN: Prospective observational study. SETTING: Primary health care and hospital settings throughout the Netherlands (January 2008-September 2011). POPULATION: Low-risk women with a singleton fetus in breech presentation, without contraindications to ECV, were offered ECV at approximately 36 weeks of gestation. METHODS: Data were collected for all ECVs performed by midwives, and were entered into a national online database. MAIN MEASURES: Successful ECV was defined as the fetus having a cephalic presentation immediately following the procedure and at birth. Complications were observed at ≤ 30 minutes and between 30 minutes and 48 hours after the ECV procedure. All serious pregnancy outcomes that occurred after the ECV procedure until birth were reported. RESULTS: A total of 47% had a successful ECv and a cephalic at the time of birth: 34% of nulliparous and 66% of multiparous women. After ECV, 57% of women gave birth vaginally: 45% of nulliparous women and 76% of multiparous women. Within 30 minutes after ECV, and between 30 minutes and 48 hours after ECV, the proportion of women experiencing a complication or serious pregnancy outcome was 0.9% and 1.8%, respectively. Serious pregnancy outcome at any time following ECV until birth was experienced by 58 (2.5%) of the women. CONCLUSIONS: The success rate of ECVs performed by trained midwives in primary health care or hospital settings is comparable with that of other providers, and the procedure is safe for low-risk women.

Travel time from home to hospital and adverse perinatal outcomes in women at term in the Netherlands.

OBJECTIVE: To study the effect of travel time, at the start or during labour, from home to hospital on mortality and adverse outcomes in pregnant women at term in primary and secondary care. DESIGN: Population-based cohort study from 2000 up to and including 2006. SETTING: The Netherlands Perinatal Registry. POPULATION: A total of 751,926 singleton term hospital births. METHODS: We assessed the impact of travel time by car, calculated from the postal code of the woman's residence to the 99 maternity units, on neonatal outcome. Logistic regression modelling with adjustments for gestational age, maternal age, parity, ethnicity, socio-economic status, urbanisation, tertiary care centres and volume of the hospital was used. MAIN OUTCOME MEASURES: Mortality (intrapartum, and early and late neonatal mortality) and adverse neonatal outcomes (mortality, Apgar <4 and/or admission to a neonatal intensive care unit). RESULTS: The mortality was 1.5 per 1000 births, and adverse outcomes occurred in 6.0 per 1000 births. There was a positive relationship between longer travel time (≥20 minutes) and total mortality (OR 1.17, 95% CI 1.002-1.36), neonatal mortality within 24 hours (OR 1.51, 95% CI 1.13-2.02) and with adverse outcomes (OR 1.27, 95% CI 1.17-1.38). In addition to travel time, both delivery at 37 weeks of gestation (OR 2.23, 95% CI 1.81-2.73) or 41 weeks of gestation (OR 1.52, 95% CI 1.29-1.80) increased the risk of mortality. CONCLUSIONS: A travel time from home to hospital of 20 minutes or more by car is associated with an increased risk of mortality and adverse outcomes in women at term in the Netherlands. These findings should be considered in plans for the centralisation of obstetric care.

[Higher perinatal mortality in The Netherlands than in other European countries: the Peristat-II study]. / Hoge perinatale sterfte in Nederland vergeleken met andere Europese landen: de Peristat-II-studie.

OBJECTIVE: Comparison of perinatal mortality in The Netherlands with that in other European countries (Peristat-II), and with data collected 5 years previously (Peristat-I). DESIGN: Descriptive study. METHOD: Indicators ofperinatal mortality which were developed for Peristat-I were used again in Peristat-II. Data on perinatal mortality in 2004 were delivered by 26 European countries. The Dutch data originated from national registers of midwives and gynaecologists and the National Neonatology Register. RESULTS: In Peristat-I, from 22 weeks gestation, The Netherlands had the highest fetal mortality rate (7.4 per 1,000 total number of births). Furthermore, after Greece, The Netherlands had the highest early neonatal mortality rate (3.5 per 1,000 live births). In Peristat-II from 22 weeks gestation, after France, The Netherlands had the highest fetal mortality rate (7.0 per 1,000 total number of births). Of all western European countries, The Netherlands had the highest early neonatal mortality rate (3.0 per 1,000 live births). Over the past 5 years the perinatal mortality rate in The Netherlands has dropped from 10.9 to 10.0 per 1,000 total births but this drop has been faster in other countries. CONCLUSION: The Netherlands has a relatively high number of older mothers and multiple pregnancies, but this only partly explains the high Dutch perinatal mortality rate which still ranks unfavourably in the European tables. More research is necessary to gain insight into the prevalence of risk factors for perinatal mortality compared with other European countries. In addition, perinatal health and the quality ofperinatal healthcare deserve a more prominent position in Dutch research programmes.

SPECT perfusion changes during complex partial seizures in patients with hippocampal sclerosis.

Cerebral perfusion changes reliably reflect changes in neuronal activity. Our aim was to obtain new insights into the pathophysiology of complex partial seizures (CPS) in patients with hippocampal sclerosis (HS) using interictal and ictal single photon emission computed tomography (SPECT). We studied 24 patients with refractory temporal lobe epilepsy (TLE) associated with HS. All had an interictal and ictal SPECT with early injection during a CPS. Images were normalized and co-registered. Using statistical parametric mapping (SPM99), brain regions with significant ictal perfusion changes were determined. To assess possible interrelationships between these regions, Pearson correlation coefficients were calculated. The temporal lobe ipsilateral to the seizure focus, the border of the ipsilateral middle frontal and precentral gyrus, both occipital lobes and two small regions in the contralateral postcentral gyrus showed ictal hyperperfusion. The frontal lobes, contralateral posterior cerebellum and ipsilateral precuneus showed hypoperfusion. Further exploratory analysis suggested an association between ipsilateral temporal lobe hyperperfusion and ipsilateral frontal lobe hypoperfusion, and an inverse association between seizure duration and hyperperfusion in the ipsilateral anterior cerebellum and contralateral postcentral gyrus. We conclude that there is a network of perfusion changes during CPS in patients with HS. Studying a particular seizure type in patients with HS with peri-ictal SPECT performed during a defined time window will allow further analysis of the cerebral network activities, and excitatory, inhibitory and gating mechanisms during seizures associated with HS.

Self-injection ictal SPECT during partial seizures.

The authors compared ictal SPECT injection performed by medical personnel with self-injection ictal SPECT in six patients with refractory temporal lobe epilepsy. Self-injection was safe and started faster. Self-injection subtraction ictal SPECT coregistered to MRI (SISCOM) was localizing in three patients who had a complex partial seizure, but only one of three patients who had a simple partial seizure, which may limit its usefulness in clinical practice. The localizing information of self-injection was better in three patients, and obviated the need for depth-EEG studies in one patient.
