[Benefit of misoprostol for prevention of postpartum hemorrhage in cesarean section: a randomized controlled trial]. / Intérêt du misoprostol dans la prévention de l'hémorragie du post-partum immédiat en cas de césarienne : essai prospectif randomisé

OBJECTIVES: To assess the benefit of sublingual misoprostol in addition to standard oxytocin in the prevention of post-partum hemorrhage at caesarean section. PATIENTS AND METHODS: This was a prospective randomized controlled clinical trial conducted from March to June 2007 at our department of obstetrics-Sousse-Tunisia, including 250 single low risk pregnant women undergoing caesarean section at gestational age>32 weeks gestation. Patients were randomly assigned to receive at cord clamping either sublingual 200microg misoprostol (Cytotec) with 20UI intravenous oxytocin (Oxytocin): bolus 10UI and infusion 10UI in 500ml Ringer Lactate): Group I, or only oxytocin at the same dose: Group II. The main outcome was total blood loss assessed by decrease in perioperative hematocrit. Secondary outcomes included measured collected blood loss, drop in hemoglobin level, additional oxytocin, side-effects and postoperative complications. RESULTS: The two groups were similar in demographic and obstetrical patient characteristics. Drop in hematocrit was more important in group II than in group I: 4.30%+/-3.14 versus. 1.10%+/-3.25; P=0.013. Drop in hemoglobin level was also more important in group II than in group I: 1.03g/dl+/-1.19 versus 0.54g/dl+/-1.17; P<0.01. Collected blood loss was less important in group I than in group II: 669.68cc+/-333.01 versus 852.52cc+/-295.08 ; P<0.01. Need for additional oxytocin and postoperative complications rate were more frequent in group II than in group I but the differences weren't significant. The rate of transient shivering, nausea and fever was significantly higher among women receiving misoprostol. CONCLUSIONS: Sublingual misoprostol (in addition to oxytocin) is effective in prevention of post-partum hemorrhage at caesarean sections when compared to oxytocin alone, without major side-effects. Larger studies are needed to confirm our results.

[Comparing two Prepidil gel regimens for cervical ripening before induction of labor at term: a randomized trial]. / Comparaison de deux régimes d'administration intracervicale de Prépidil dans le déclenchement artificiel du travail à terme : essai prospectif randomisé

OBJECTIVES: To compare efficacy and safety of two regimens of intracervical dinoprostone (Prepidil) in cervical ripening before labor induction at term. PATIENTS AND METHODS: This was a prospective randomized clinical study including 148 patients with single pregnancy, viable fetus at gestational age greater than 36 weeks gestation and a Bishop score less than five, who required induction of labor. Patients were randomised to receive either repeated doses of dinoprostone gel 0.5mg (Prepidil) every 6 hours (group I) or every 12 hours (group II) for maximum three times before inducing labor with Oxytocin. The main outcome was the rate of caesarean sections. RESULTS: The two groups were similar in patient characteristics, indication for labor induction and preinduction Bishop scores. The caesarean rate was lower in group I (20.3%) than in group II (23%); though the difference did not reach statistical difference: p=0.69. Delivery rate in the first 24 hours was significantly higher in group I (62.2%) than in group II (40.5%); p=0.009. Prepidil secondary effects were experienced in 8.1% of patients in group I versus 1.4% in group II; p=0.11. Median umbilical artery pH at birth was 7.232+/-0.47 in group I and 7.294+/-0.58 in group II; p=0.30. Maternofetal infections rate was lower in group I (1.4%) than in group II (2.7%) without significant difference (p=0.56). CONCLUSIONS: Repeated intracervical doses of Prepidil every 6 hours, in cervical ripening before labor induction at term, enables higher delivery rate in the first 24 hours without inducing excess of caesarean sections or maternofetal morbidity when compared to its administration every 12 hours.

Declenchement du travail sur uterus cicatriciel. A propos de 100 cas

But : Evaluer l'efficacite et l'innocuite de la maturation cervicale et du declenchement artificiel du travail sur uterus cicatriciel. Materiel et methodes : Etude retrospective et analytique portant sur 100 patientes porteuses d'uterus uni cicatriciel ayant beneficie d'un declenchement du travail avec ou sans maturation cervicale entre le 01 janvier 2002 et 31 decembre 2003. Resultats : le succes de la maturation a ete observe dans 63;1des cas. Le taux global d'accouchement par voie basse est de 74; plus faible (69;8) en cas de score de Bishop initial defavorable. Le taux de rupture uterine est de 3. La mortalite maternelle est nulle. Le score d'Apgar moyen a la 5eme minute est de 9;7; et la mortalite neonatale est nulle. Conclusion : Le declenchement artificiel du travail sur uterus uni cicatriciel a permis d'eviter 74des cesariennes iteratives sans augmentation statistique-ment significative de la morbidite materno-fotale. Ces resultats encourageants; meritent d'etre valides par des etudes prospectives

[Contribution of intracervical PGE2 administration in premature rupture of the membranes at term. Prospective randomised clinical trial]. / Apport de l'administration intracervicale de PGE2 dans les ruptures prématurées des membranes à terme. Essai clinique prospectif randomisé.

OBJECTIVE: To compare the clinical effectiveness and safety of intracervical dinoprostone versus conservative management of term prelabor rupture of membranes. SUBJECTS AND METHODS: 88 women with term prelabor rupture of membranes were assigned randomly to one of two groups RESULTS: 44 women were allocated in each group. The means (+/- S. D) intervals from PROM to delivery and from inclusion to start of labour were significantly shorter in the dinoprostone group (19.5+/-6.2 vs 25.5+/-7.7 hours p<0.01 and 8.7+/-5.5 hours vs 14+/-6. 8; p=0.32 respectively). No significant differences were observed in the mean duration of labour (4.5+/-1.6 hours vs. 4.9+/-1.67 p=0.32). The rates of clinical amniotits were 15.9% in the dinoprostone group and 6.8% in the control group; difference is not statistically significant (p=0.17). The mode of delivery and Apgar score were similar in the two groups. Uterine tachysystole occurred more frequently in the dinoprostone group (6.8 vs 0%) but did not reach statistical significance. CONCLUSION: Intracervical administration of dinoprostone with prelabor rupture of membrane at term and unripened cervix shortens the interval to delivery without a significant increase of maternal or neonatal morbidity.
