The use of episiotomy in a low-risk population in the Netherlands: a secondary analysis.

BACKGROUND: To examine the episiotomy incidence and determinants and outcomes associated with its use in primary care midwifery practices. METHODS: Secondary analysis of two prospective cohort studies (n = 3,404). RESULTS: The episiotomy incidence was 10.8 percent (20.9% for nulliparous and 6.3% for parous women). Episiotomy was associated with prolonged second stage of labor (adj. OR 12.09 [95% CI 6.0-24.2] for nulliparous and adj. OR 2.79 [1.7-4.6] for parous women) and hospital birth (adj. OR 1.75 [1.2-2.5] for parous women). Compared with episiotomy, perineal tears were associated with a lower rate of postpartum hemorrhage in parous women (adj. OR 0.58 [0.4-0.9]). Fewer women with perineal tears reported perineal discomfort (adj. OR 0.35 [0.2-0.6] for nulliparous and adj. OR 0.22 [0.1-0.3] for parous women). Among nulliparous women episiotomy was performed most frequently for prolonged second stage of labor (38.8%) and among parous women for history of episiotomy or prevention of major perineal trauma (21.1%). CONCLUSIONS: The incidence of episiotomy is high compared with some low-risk settings in other Western countries. Episiotomy was associated with higher rates of adverse maternal outcomes. Restricted use of episiotomy is likely to be beneficial for women.

Risk of perineal damage is not a reason to discourage a sitting birthing position: a secondary analysis.

AIM: To examine the association between semi-sitting and sitting position at the time of birth and perineal damage amongst low-risk women in primary care. BACKGROUND: Evidence on the association between birthing positions and perineal trauma is not conclusive. Most studies did not distinguish between positions during the second stage of labour and position at the time of birth. Therefore, although birthing positions do not seem to affect the overall perineal trauma rate, an increase in trauma with upright position for birthing cannot be ruled out. METHODS: Secondary analysis was performed on data from a large trial. This trial was conducted amongst primary care midwifery practices in the Netherlands. A total of 1646 women were included who had a spontaneous, vaginal delivery. Perineal outcomes were compared between women in recumbent, semi-sitting and sitting position. Logistic regression analysis was used to examine the effects of these positions after controlling for other factors. FINDINGS: No significant differences were found in intact perineum rates between the position groups. Women in sitting position were less likely to have an episiotomy and more likely to have a perineal tear than women in recumbent position. After controlling for other factors, the odds ratios (OR) were 0.29 [95% confidence interval (CI): 0.16-0.54] and 1.83 (95% CI: 1.22-2.73) respectively. Women in semi-sitting position were more likely to have a labial tear than women in recumbent position (OR: 1.43, 95% CI: 1.00-2.04). CONCLUSION: A semi-sitting or sitting birthing position does not need to be discouraged to prevent perineal damage. Women should be encouraged to use positions that are most comfortable to them.

Increased blood loss in upright birthing positions originates from perineal damage.

OBJECTIVE: To assess whether the risk of severe blood loss is increased in semi-sitting and sitting position, and if so, to which extent blood loss from perineal damage is responsible for this finding. DESIGN: Secondary analysis of data from a large trial. SETTING: Primary care midwifery practices in the Netherlands. POPULATION: About 1646 low-risk women who had a spontaneous vaginal delivery. METHODS: Blood loss was measured using a weighing scale and measuring jug. Logistic regression analysis was used to examine the net effects of birthing position and perineal damage on blood loss greater than 500 ml. MAIN OUTCOME MEASURES: Mean total blood loss and incidence of blood loss greater than 500 ml and 1000 ml. RESULTS: Mean total blood loss and the incidence of blood loss greater than 500 ml and 1000 ml were increased in semi-sitting and sitting position. In logistic regression analysis, the interaction between birthing position and perineal damage was almost significantly associated with an increased risk of blood loss greater than 500 ml. Semi-sitting and sitting position were only significant risk factors among women with perineal damage (OR 1.30, 95% CI 1.00-1.69 and OR 2.25, 95% CI 1.37-3.71, respectively). Among women with intact perineum, no association was found. CONCLUSIONS: Semi-sitting and sitting birthing positions only lead to increased blood loss among women with perineal damage.

Periconceptional smoking: an exploratory study of determinants of change in smoking behavior among women in the fertile age range.

How can women who are not yet pregnant be motivated to stop smoking before they become pregnant? Epidemiological studies have suggested that periconceptional smoking and smoking during the first trimester of the pregnancy may lead to congenital abnormalities. To motivate women to stop smoking before pregnancy, more insight is needed into the differences between 'smoking' women who want to have children and those who do not. A sample of 931 women (65% response rate) aged 15-45 years returned a questionnaire with questions about their smoking behavior, wish to have children, risk perceptions, attitude to smoking, personal efficacy and stage of readiness to change. In spite of some positive outcomes (e.g. negative attitude to smoking, relatively high risk perceptions of the relationship between congenital anomalies and smoking), one cannot automatically assume that these women will stop smoking before they get pregnant. (1) Beliefs, attitude and readiness to change were not well integrated and grounded cognitively. (2) Women who smoked were pessimistic about their ability to quit. Future campaigns need to 'invite' women to associate and to integrate risk information about the relationship between smoking and congenital abnormalities with other cognitions (attitude, intention). It is also important to instruct women in how to stop smoking and to remain non-smokers.

Counselling following the Prenatal Diagnosis of Klinefelter Syndrome: Comparisons between Geneticists and Obstetricians in Five European Countries.

Objective: To describe and compare the information obstetricians and geneticists in five European countries report they would give following the prenatal diagnosis of Klinefelter syndrome. Methods: 388 obstetricians and 269 geneticists from Germany, the Netherlands, Portugal, Spain and the UK completed a brief questionnaire assessing two variables: the information they reported providing to parents following the prenatal diagnosis of Klinefelter syndrome (categorized as positive or negative); and their perceptions of the quality of life with the condition. Results: Geneticists were more likely than obstetricians to report providing more positive than negative information about Klinefelter syndrome than equal amounts of positive and negative information or more negative than positive information about the condition (excess positive information). Regardless of specialty, the information that health professionals reported providing was predicted by their perceptions of the quality of life with the condition, and the country from which they came. Those perceiving quality of life as greater were more likely to provide an excess positive information, as were health professionals from Germany and the UK. Conclusions: These results suggest that the information parents across Europe receive after the prenatal diagnosis of Klinefelter syndrome varies according to the specialty and country of the health professionals consulted, and their perceptions of quality of life with the condition. This variation seems to reflect personal, cultural and professional differences between health professionals. Copyright 2002 S. Karger AG, Basel
