Oral Misoprostol (oral + misoprostol)
Selected AbstractsOral misoprostol for the prevention of primary post-partum hemorrhage during third stage of laborJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 6 2007Christopher A. Enakpene Abstract Aim:, To assess the effectiveness of oral misoprostol compared with methylergometrine in the prevention of primary post-partum hemorrhage during the third stage of labor. Methods:, This was a randomized controlled trial of 864 singleton low-risk pregnant women. The outcomes were total blood loss, duration of the third stage of labor and peripartal change in hematocrit. Comparisons were by the ,2 -test and Student t -test. Relative risks were calculated for side-effects profile. A P -value of less than 0.05 was statistically significant. Results:, The biodata of all the participants were similar. The mean blood loss for the misoprostol and methylergometrine groups was 191.6 ± 134.5 mL and 246.0 ± 175.5 mL, respectively (95% CI: ,79.3 to ,39.5 mL). The mean duration of the third stage of labor was 19.6 ± 2.4 min and 9.4 ± 3.3 min in the misoprostol and methylergometrine groups, respectively (95% CI: 9.82,10.58 min). More subjects had blood loss >500 mL, 42 (9.7%) versus 6 (1.4%), and peripartal hematocrit change greater than 10%, 38 (8.8%) versus 5 (1.2%), in the methylergometrine group than in the misoprostol group, respectively. Also, more subjects received additional oxytocic in the methylergometrine group, compared to the misoprostol group (80 [18.5%] versus 33 [7.6%] patients, respectively). Conclusions:, Orally administered misoprostol was more effective in reducing blood loss during the third stage of labor than intramuscular methylergometrine. However, there were more subjects in the misoprostol group in whom duration of the third stage of labor was greater than 15 min and who also had manual placental removal than in the methylergometrine group.

Shetty Objective To compare the efficacy of 100 ,g of oral misoprostol with 3 mg prostaglandin E2 vaginal tablets in term labour induction. Design A non-blinded, randomised, controlled trial. Setting A tertiary level, teaching Scottish Hospital. Population Two hundred women at term with indications for labour induction and modified Bishop's cervical score of less than 8. Methods The women were randomly allocated to receive either 100 ,g of misoprostol orally (which could be repeated 4 hourly to a maximum of five doses if indicated), or a 3 mg tablet of prostaglandin E2 vaginally (which could be repeated in 6 hours, according to routine departmental protocol). Main outcome measure The number delivering vaginally within 24 hours of the induction. Results Seventy-five women delivered vaginally in the misoprostol group and 73 in the PGE2 group. Of these, 50.7% in the misoprostol group and 54.8% in the PGE2 group delivered within 24 hours of the induction (RR 0.92, 95% CI 0.7 to 1.3). More women in the misoprostol group were given oxytocin, but this was not statistically significant (60%vs 47%, RR 1.3, 95% CI 0.98 to 1.7). Two women in the misoprostol group had uterine hyperstimulation. The neonatal outcomes were not significantly different in the two groups. There was a £1100 saving on direct drug costs in the misoprostol group. Conclusions Oral misoprostol (100 ,g) has similar efficacy to vaginal PGE2 tablets, and may be an option to consider for term labour induction. [source] Labour characteristics and uterine activity: misoprostol compared with oxytocin in women at term with prelabour rupture of the membranesBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 2 2000Suk Wai Ngai Assistant Professor Objective To compare the labour pattern and uterine activity of oral misoprostol with oxytocin for labour induction in women presenting with prelabour rupture of membranes at term. Design Prospective randomised study. Setting Department of Obstetrics and Gynaecology, Queen Mary Hospital, Hong Kong. Participants Eighty women presenting with prelabour rupture of membranes at term. Methods The women were randomised to receive either 100 ,g misoprostol orally every 4 hours to a maximum of three doses, or intravenous oxytocin infusion according to the hospital protocol. Intrauterine pressure transducers were inserted one hour before induction of labour in both groups of women. We compared the pattern of uterine activity, the induction-to-delivery interval, duration of labour, mode of delivery and neonatal outcome between the two groups. Results Both oxytocin and oral misoprostol caused an increase in uterine activity within one hour of labour induction. Peak uterine activity was reached 6,8 h after oral misoprostol, with persistent effects, and 8,10 h after oxytocin, requiring continuous titration of medication. The duration of labour was significantly reduced in nulliparous women, but not in those who were multiparous in the misoprostol group. The induction-to-delivery interval, the mode of delivery and the perinatal outcome were similar for the two groups. Conclusion Oral misoprostol caused earlier peak uterine activity, compared with oxytocin (6,8 h vs 8,10 h). Oral misoprostol was not only as effective as oxytocin in inducing labour in women at term with prelabour rupture of the membranes, but it reduced significantly the duration of labour in nulliparous women.

[source] Titrated low-dose vaginal and/or oral misoprostol to induce labour for prelabour membrane rupture: a randomised trialBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 12 2008L Bricker Objective, To evaluate the clinical effectiveness and safety of titrated low-dose misoprostol for induction of labour (IOL) in the presence of prelabour rupture of membranes (PROM). Design, Randomised controlled trial. Setting, Maternity units in the UK (9) and Egypt (1). Population, Women >34 weeks of gestation with PROM, singleton viable fetus and no previous caesarean section. Methods, Subjects randomised to IOL with a titrated low-dose misoprostol regimen (oral except if unfavourable cervix, where initial dose vaginal) or a standard induction method, namely vaginal dinoprostone followed by intravenous oxytocin if the cervix was unfavourable or intravenous oxytocin alone if the cervix was favourable. Main outcome measures, Primary outcome measures were caesarean section and failure to achieve vaginal delivery within 24 hours. Analysis was by intention to treat. Results, The trial did not achieve the planned sample size of 1890 due to failure in obtaining external funding. Seven hundred and fifty-eight women were randomised (375 misoprostol and 383 standard). There were less caesarean section (14 versus 18%, relative risk [RR] 0.79; 95% CI 0.57,1.09) and less women who failed to achieve vaginal delivery within 24 hours in the misoprostol group (24 versus 31%, RR 0.79; 95% CI 0.63,1.00), but the differences were not statistically significant. Subgroup analysis showed that with unfavourable cervix, misoprostol may be more effective than vaginal dinoprostone. There was no difference in hyperstimulation syndrome. There were more maternal adverse effects with misoprostol, but no significant differences in maternal and neonatal complications. Conclusions, Titrated low-dose misoprostol may be a reasonable alternative for IOL in the presence of PROM, particularly in women with an unfavourable cervix. Safety and rare serious adverse events could not be evaluated in a trial of this size. [source] Fertility control: Oral versus self-administered vaginal misoprostol at home before surgical termination of pregnancy: a randomised controlled trialBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 1 2006Kevin Sunde Oppegaard 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] Medical management of early fetal demise using sublingual misoprostolBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 4 2002Prabhath T. Wagaarachchi The aim of this study was to determine the efficacy of mifepristone in combination with sublingual misoprostol for the medical management of early fetal demise. Fifty-six consecutive women were studied prospectively. The mean (SD) gestation at diagnosis was 9.6 weeks (1.84). Four women had complete miscarriage with mifepristone alone. The overall success rate was 83.9% and the median induction,miscarriage interval was 8.19 hours (range 0.83 to 37.50 hours). Of those women who had a successful outcome, 91.5% were satisfied with the regimen. Sublingual misoprostol in combination with mifepristone is an effective and safe alternative to vaginal or oral misoprostol in the management of early fetal demise. [source] Postpartum intrauterine pressure studies of the uterotonic effect of oral misoprostol and intramuscular syntometrineBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 1 2001Y.S. Chong Objectives To investigate the effect of oral misoprostol in dosages varying from 200 ,g to 800 ,g on postpartum uterine contractility and to establish their side effects. Design A prospective descriptive study. Participants Fifty-seven women who delivered vaginally after spontaneous labours not requiring augmentation. Methods Within 5 minutes of delivery of the placenta, a calibrated Gaeltec catheter with an intrauterine pressure transducer at its tip was inserted transcervically into the uterine cavity. Cumulative uterine activity was recorded for 30 minutes in each woman before administering the oral misoprostol tablets and continued for a further 90 minutes after its administration. Thus each woman acted as her own control regarding changes in uterine contractility. Uterine activity was recorded on a Sonicaid Meridian fetal monitor, which measures active contraction area automatically. The incidence of side effects was also recorded. Results There was no statistical difference (P=0.887) in the adjusted mean difference in cumulative uterine activity following all the doses of oral misoprostol, compared with intramuscular syntometrine, the largest difference being seen in oral misoprostol 200 ,g (adjusted mean difference ,2282 kPas s, 95% CI ,7954 to 3390 kPas s). The mean onset of action of oral misoprostol (6.1, SD 2.1 min) was significantly slower than that of intramuscular syntometrine (3.2, SD 1.5 min; P=0.002), but their durations of action were similar (P=0.637). In the misoprostol group the commonest side effects were shivering (36%) and a rise in body temperature above 38°C (40%). In the syntometrine group, the most commonly observed side effect was moderate uterine pain (nine out of ten women) and a rise in diastolic blood pressure of 20 mmHg (two out of ten women). Conclusion The results of this study show that oral misoprostol has a definite uterotonic effect on the postpartum uterus. At doses of 200 ,g to 400 ,g, oral misoprostol has a similar uterotonic effect to intramuscular syntometrine. Higher doses of oral misoprostol are associated with significantly more side effects.

Design Prospective randomised study. Setting Department of Obstetrics and Gynaecology, Queen Mary Hospital, Hong Kong. Participants Eighty women presenting with prelabour rupture of membranes at term. Methods The women were randomised to receive either 100 ,g misoprostol orally every 4 hours to a maximum of three doses, or intravenous oxytocin infusion according to the hospital protocol. Intrauterine pressure transducers were inserted one hour before induction of labour in both groups of women. We compared the pattern of uterine activity, the induction-to-delivery interval, duration of labour, mode of delivery and neonatal outcome between the two groups. Results Both oxytocin and oral misoprostol caused an increase in uterine activity within one hour of labour induction. Peak uterine activity was reached 6,8 h after oral misoprostol, with persistent effects, and 8,10 h after oxytocin, requiring continuous titration of medication. The duration of labour was significantly reduced in nulliparous women, but not in those who were multiparous in the misoprostol group. The induction-to-delivery interval, the mode of delivery and the perinatal outcome were similar for the two groups. Conclusion Oral misoprostol caused earlier peak uterine activity, compared with oxytocin (6,8 h vs 8,10 h). Oral misoprostol was not only as effective as oxytocin in inducing labour in women at term with prelabour rupture of the membranes, but it reduced significantly the duration of labour in nulliparous women.
