Abstract Aim:, This prospective, observational study was an attempt to evaluate whether a positive cervical phosphorylated insulin-like growth factor binding prote,n-1 admission test in women with signs and symptoms of preterm labor (PTL) may be useful in the prediction of women who will deliver prematurely. Methods:, Pregnant women with confirmed gestational age between 24 and 37 weeks' gestation with <3 cm cervical dilatation and intact membranes were included in the study. Prior to digital examination, a sterile speculum examination was performed using a dacron swab rotated in the external cervical os for 15 s. The test was based on immunochromatographic qualitative analysis of cervical phosphorylated insulin-like growth factor binding prote,n-1. Test (+) and (,) cases were evaluated in terms of maternal demographic characteristics and neonatal outcomes. Results:, A total of 68 cases were enrolled in the study. There were no statistically significant differences between test (+) and (,) groups, in terms of maternal characteristics or adverse neonatal outcomes. However, cases with + test had high Bishop scores on admission (P = 0.01) and gestational age at delivery (P = 0.003). For deliveries within 7 days of admission, the strongest predictors were test positivity (RR:24,%95CI:2.8,204, P < 0.0001) and Bishop score (RR:1.3, %95CI: 1.0,1.6, P = 0.03). For deliveries <34 weeks' gestation, the test had a sensitivity, specificity, positive predictive values, negative predictive values, +likelihood ratios and ,likelihood ratios of 70%, 74%, 48%, 88, 2.8 and 0.39, respectively. Conclusion:, Among women with signs and symptoms of PTL, the high negative predictive value of this test to predict the PTL <34 weeks' gestation as well as within 7 days of delivery may be of value in the reassurance of patients, avoiding unnecessary medical interventions.

Abstract Aim: To investigate the efficacy of vaginal misoprostol for cervical priming before dilatation and curettage in postmenopausal women. Methods: Forty-four postmenopausal women with indication for dilatation and curettage were randomly assigned to receive either 400 µg of misoprostol or placebo vaginally 6 h before dilatation and curettage. The main outcome measures were the number of women who required cervical dilatation, cervical width, time taken to dilate to Hegar 6 and other complications. Results: The mean cervical diameter (4.59 millimeters in the misoprostol group vs 4.41 millimeters in the placebo group) was comparable between the two groups. A similar number of women in the misoprostol group and in the placebo group required cervical dilatation (12 vs 16, P = 0.35). The operative times for both groups were similar. The incidence of side-effects was comparable in both groups. There were two uterine perforations in the misoprostol group (2 vs 0). Conclusion: There was no significant benefit from applying 400 µg vaginal misoprostol 6 h prior to dilatation and curettage in postmenopausal women. [source]

Abstract Aims Stress urinary incontinence (SUI) in young women is usually the result of pelvic floor injury during vaginal delivery. Whether cesarean section delivery may prevent such injury is questionable. We undertook a prospective study to compare the prevalence of SUI among primiparae 1 year after spontaneous vaginal delivery versus elective cesarean section, or cesarean section performed for obstructed labor. Methods Three hundred and sixty-three consecutive primiparae were recruited immediately after delivery and were followed for 1 year. Women were asked upon recruitment whether they had ever experienced SUI before pregnancy. Those who had SUI before pregnancy were excluded. Thus, only cases of de novo childbirth-associated SUI were analyzed. Patients were divided into three subgroups according to the mode of delivery: spontaneous vaginal delivery (n,=,145), elective cesarean section (n,=,118), and cesarean section performed for obstructed labor (n,=,100). Patients who underwent elective cesarean section were not given a trial of labor. Cesarean sections for obstructed labor were performed at a mean cervical dilatation of 8.7,±,1.6 cm and arrest of 184,±,24 min. Prevalence, frequency, and severity of postpartum SUI, as well as demographic and obstetric parameters, were analyzed in each subgroup. Results The three subgroups were comparable with respect to maternal age, weight, and height. Prevalence of postpartum SUI was similar after spontaneous vaginal delivery (10.3%) and cesarean section performed for obstructed labor (12%). However, SUI was significantly less common following elective cesarean section with no trial of labor (3.4%, P,<,0.05). Approximately half of the symptomatic patients in each subgroup reported either moderate or severe symptoms, however, only 15,18% expressed their desire for further evaluation. Conclusions Prevalence of postpartum SUI is similar following spontaneous vaginal delivery and cesarean section performed for obstructed labor. It is quite possible that pelvic floor injury in such cases is already too extensive to be prevented by surgical intervention. Conversely, elective cesarean section, with no trial of labor, was found to be associated with a significantly lower prevalence of postpartum SUI. Whether the prevention of pelvic floor injury should be an indication for elective cesarean section is yet to be established. Neurourol. Urodynam. 23:2,6, 2004. © 2003 Wiley-Liss, Inc. [source]


Is routine cervical dilatation necessary during elective caesarean section?

AUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 3 2009
A randomised controlled trial
Objective: The purpose of this prospective randomised study was to determine the effect of routine cervical dilatation during elective caesarean section on maternal morbidity. Methods: Participants with indication for elective caesarean section were randomly allocated to two groups. Group A (n = 200) women with intraoperative cervical dilatation; group B (n = 200) women with no intraoperative cervical dilatation. Results: No demographic differences were observed between groups. There was no significant difference between groups in infectious morbidity (P = 0.87) (relative risk (RR) 1.11, 95% confidence interval (CI) 0.58,2.11), endometritis (P = 0.72) (RR 1.68, 95% CI 0.39,7.14), febrile morbidity (P = 0.66) (RR 1.21, 95% CI 0.51,2.87), wound infection (P = 0.82) (RR 1.11, 95% CI 0.44,2.81), endometritis (P = 0.72) (RR 1.68, 95% CI 0.39,7.14) or urinary tract infection (P = 1.00) (RR 1.00, 95% CI 0.28,3.50), and estimated blood loss (P = 0.2). However, group A had longer operative times compared with the group B (P = 0.01). Conclusion: Intraoperative digital cervical dilatation during elective caesarean section did not reduce blood loss and postoperative infectious morbidity. The routine digital cervical dilatation during elective caesarean section is not recommended. [source]

Objective, To compare the impact of 1000 micrograms of self-administered vaginal misoprostol versus self-administered vaginal placebo at home on preoperative cervical ripening in both premenopausal and postmenopausal women before operative hysteroscopy. Design, Two separate but identical parallel, randomised, double-blind, placebo-controlled sequential trials, one in premenopausal women and one in postmenopausal women. The boundaries for the sequential trials were calculated on the primary outcomes of a difference of cervical dilatation ,1 mm, with the assumption of a type 1 error of 0.05 and a power of 0.95. Setting, Norwegian university teaching hospital. Sample, Eighty-six women referred to outpatient operative hysteroscopy. Methods, The women were randomised to either 1000 micrograms of self-administered vaginal misoprostol or self-administered vaginal placebo the evening before outpatient operative hysteroscopy. Main outcome measures, Preoperative cervical dilatation (primary outcome), number of women who achieve a preoperative cervical dilatation ,5 mm, acceptability, complications and adverse effects (secondary outcomes). Results, In premenopausal women, the mean cervical dilatation was 6.4 mm (SD 2.4) in the misoprostol group and 4.8 mm (SD 2.0) in the placebo group, the mean difference in cervical dilatation being 1.6 mm (95% CI 0.5,2.7). Among the premenopausal women receiving misoprostol, 88% achieved a cervical dilatation of ,5 mm compared with 65% in the placebo group. Twelve percent of the women who received misoprostol were difficult to dilate compared with 32% who received placebo. Dilatation was also quicker in the misoprostol group. Misoprostol had no effect on cervical ripening in postmenopausal women compared with placebo, and 43% of the women were difficult to dilate. The trials were terminated after analysis of 21 postmenopausal women and 65 premenopausal women after reaching a conclusion on the primary outcome with only 28% of the number of women needed in a fixed sample size trial. Three of 45 women who received misoprostol experienced severe lower abdominal pain, and there was an increased occurrence of light preoperative bleeding in the misoprostol group. Most women did not experience misoprostol-related adverse effects. The majority (83% of premenopausal and 76% of postmenopausal women) found self-administered vaginal misoprostol at home to be acceptable. There were two serious complications in the premenopausal misoprostol group: uterine perforation with subsequent peritonitis and heavy postoperative bleeding requiring blood transfusion, but these were not judged to be misoprostol related. Complications were otherwise comparatively minor and distributed equally between the two dosage groups. Conclusions, One thousand micrograms of self-administered vaginal misoprostol 12 hours prior to operative hysteroscopy has a significant cervical ripening effect compared with placebo in premenopausal but not in postmenopausal women. Self-administered vaginal misoprostol of 1000 micrograms at home the evening before operative hysteroscopy is safe and highly acceptable, although a small proportion of women experienced severe lower abdominal pain. There is a risk of lower abdominal pain and light preoperative bleeding with this regimen, which is very cheap and easy to use. [source]

Objective, To compare the impact of 400 ,g oral versus self-administered vaginal misoprostol at home on pre-operative cervical priming in both primigravid and multigravid women prior to first trimester surgical abortion. Design, Randomised controlled trial. Setting, Norwegian University Teaching Hospital. Sample, Three hundred and thirty-eight women undergoing surgical abortion between 7 and 12 weeks of gestation. Methods, The women were randomised to either 400 ,g of oral misoprostol the evening before or 400-,g of self-administered vaginal misoprostol at home the same day as vacuum aspiration. Main outcome measures, Pre-operative cervical dilatation, complications and acceptability. Results, The median cervical dilatation was 6.2 mm (range 0,11 mm) for the women in the 400 ,g oral misoprostol and 6.5 mm (range 0,11 mm) in the 400-,g vaginal misoprostol groups. The median pre-operative dilatation was larger in multigravidae (6.4 and 6.7 mm for the oral and vaginal routes, respectively) than in primigravidae (5.8 and 6.0 mm, respectively). In primigravidae, 19% achieved a pre-operative dilatation of ,7 mm, with no significant difference between oral and vaginal dosage. In multigravidae, 52% achieved a pre-operative dilatation of ,7 mm with vaginal dosage, compared with 36% with oral dosage (P= 0.03). There was no difference between non-immigrant versus immigrant women in pre-operative cervical dilatation. The 400-,g oral dosage group had a higher risk of bleeding, compared with the group receiving 400-,g vaginal misoprostol [odds ratio (OR) = 10.4; confidence interval (CI) 5.2,20.8]. There was no difference between non-immigrant and immigrant women in acceptability of self-administered vaginal misoprostol; almost all women found this administration route acceptable. Complications were minor and were distributed equally between the two dosage groups. Conclusions, The vaginal route will result in a satisfactory dilatation in about half of multigravidae but is much less effective in primigravidae. The oral route does not lead to satisfactory dilatation in either group and is associated with a higher occurrence of pre-operative bleeding. Self-administered vaginal misoprostol at home is highly acceptable. [source]

Objective To study the effects of oral carbohydrate ingestion on clinical outcome and on maternal and fetal metabolism. Design Prospective, double-blind, randomised study. Setting Leyenburg Hospital, The Hague, The Netherlands. Population Two hundred and two nulliparous women. Methods In labour, at 8 to 10 cm of cervical dilatation, the women were asked to drink a solution containing either 25 g carbohydrates or placebo. In a subgroup of 28 women, metabolic parameters were measured. Main outcome measures Number of instrumental deliveries, fetal and maternal glucose, free fatty acids, lactate, pH, Pco2, base excess/deficit and ,-hydroxybutyrate. Results Drinking a carbohydrate-enriched solution just before starting the second stage of labour did not reduce instrumental delivery rate (RR 1.1, 95% CI 0.9,1.3). Caesarean section rate was lower in the carbohydrate group, but the difference did not reach statistical significance (1%vs 7%, RR 0.2, 95% CI 0.02,1.2). In the carbohydrate group, maternal free fatty acids decreased and the lactate increased. In the umbilical cord there was a positive venous,arterial lactate difference in the carbohydrate group and a negative one in the placebo group, but the differences in pH and base deficit were comparable. Conclusion Intake of carbohydrates just before the second stage does not reduce instrumental delivery rate. The venous,arterial difference in the umbilical cord suggested lactate transport to the fetal circulation but did not result in fetal acidaemia. [source]

Objective To assess the effects of delayed vs immediate pushing in second stage of labour with epidural analgesia on delivery outcome, postpartum faecal continence and postpartum anal sphincter and pudendal nerve function. Design Prospective, randomised, controlled trial. Setting Tertiary referral maternity teaching hospital. Population One hundred and seventy nulliparous women randomised at full dilatation to immediate or delayed pushing. Methods A total of 178 nulliparous women, all with continuous epidural analgesia, were randomised at full cervical dilatation, but before the fetal head had reached the pelvic floor, to either immediate pushing or 1 hour delayed pushing. Labour outcome was analysed and all women underwent postpartum assessment of anal sphincter function, including anal manometry. Those women who had a normal delivery underwent neurophysiology studies, while those women who had an instrumental delivery underwent endoanal ultrasound. Main outcome measures Mode of delivery; altered faecal continence. Results Ninety women were randomised to immediate pushing and 88 to delayed pushing. The spontaneous delivery rate was 56% (50/90) in the immediate pushing group and 52% (46/88) in the delayed pushing group. Mean duration of labour for the immediate pushing group was 427 minutes compared with 480 minutes for the delayed pushing group (P= 0.005). Eighty-four percent (76/90) of women in the immediate pushing group received oxytocin to augment labour, 21/76 (28%) in the second stage only. Eighty-one percent (71/88) of women in the delayed pushing group received oxytocin to augment labour, 22/71 (31%) in the second stage only. Fetal outcome did not differ between the two groups. Episiotomy rates were 73% and 69% in the immediate pushing and delayed pushing groups, respectively. 26% (23/90) of the immediate pushing group and 38% (33/88) of the delayed pushing group complained of altered faecal continence after delivery (NS). Manometry, ultrasound and neurophysiology studies did not differ significantly between the two groups. Overall, 55% of women after instrumental delivery had endosonographic evidence of damage to the external anal sphincter, while 36% of women after spontaneous delivery had abnormal neurophysiology studies. Conclusions Rates of instrumental delivery were similar following immediate and delayed pushing, in association with epidural analgesia. Delayed pushing prolonged labour by 1 hour but did not result in significantly higher rates of altered continence or anal sphincter injury, when compared with immediate pushing. [source]
