A Comparison of Misoprostol and Dinoprostone Gel for Induction and Cervical Ripening

Introduction: Labour induction at term is a universal conventional obstetric interference with an objective to stimulate uterine contractions artificially to attain a spontaneous vaginal delivery. The current study was aimed to compare the efficacy and safety profile of low dose vaginal Misoprostol with Dinoprostone gel for induction of labour in term pregnancies with unfavorable cervix and intact membranes. Methodology: This Randomized Controlled Trial was conducted among pregnant women with term pregnancy with obstetrical or medical indication for induction of labour after institutional ethical committee approval. A detailed history, complete physical examination and investigations were done for all patients. Result: Misoprostol and Dinoprostone gel are equally effective inducing agents. Both are equally effective in Primigravida and Multigravida. Failure of induction rate for Misoprostol and Dinoprostone was statistically not significant. The need of Oxytocin augmentation, maternal complication rate, NICU admission rate, caesarean section rate and occurrence of meconium-stained liquor are statistically not significant in both the study groups. Our study was unable to demonstrate superiority of any single drug compared to other. Only the difference is cost, induction with Conclusion: considering the easy to preserve and administer, we recommend use of Misoprostol as a safe, effective, cheaper, and more convenient drug for induction of labour.

Eficacia y seguridad del misoprostol vaginal comparado con dinoprostona en maduración cervical e inducción del parto / Effectiveness and safety of vaginal misoprostol vs dinoprostone for cervical ripening and labour induction

Resumen OBJETIVO: Comparar la eficacia del misoprostol intravaginal con el dispositivo vaginal de liberación prolongada de dinoprostona en la inducción del parto. Además, analizar el perfil de seguridad en relación con los desenlaces maternos y perinatales. MATERIALES Y MÉTODOS: Estudio retrospectivo y comparativo efectuado en pacientes atendidas entre 2018 y 2020 en el Área Sanitaria de Ferrol, La Coruña, España, con partos que se iniciaron con inducción con prostaglandinas. Las pacientes se dividieron en dos cohortes, en función de la prostaglandina sintética administrada (misoprostol por vía vaginal o dinoprostona en dispositivo intravaginal). Para la comparación entre ambos grupos se aplicó la prueba U de Mann-Whitney. Para las variables cualitativas se describió su cantidad total y el porcentaje, que se compararon con prueba de χ2 de Pearson. RESULTADOS: Se analizaron 508 pacientes con inducción del parto. En las indicaciones de ésta no se encontraron diferencias entre uno y otro grupo, aunque destacó la indicación del misoprostol en pacientes con embarazo cronológicamente prolongado (63%) y de dinoprostona en rotura prematura de membranas (49%). En relación con los desenlaces perinatales, se registró un Apgar menor de 7 a los 5 minutos en 2 pacientes tratadas con dinoprostona y 1 con misoprostol; así como un pH arterial umbilical menor de 7.10 en 8 pacientes tratadas con dinoprostona y 7 con misoprostol. CONCLUSIONES: Los datos aquí reportados hacen suponer que ambas prostaglandinas consiguen una tasa de inicio del parto similar, aunque la dinoprostona parece reducir el tiempo hasta el inicio del parto en mujeres con indicación de inducción.

Abstract OBJECTIVE: To compare the efficacy of intravaginal misoprostol with the dinoprostone extended-release vaginal device in labor induction. In addition, to analyze the safety profile in relation to maternal and perinatal outcomes. MATERIALS AND METHODS: Retrospective and comparative study performed in patients attended between 2018 and 2020 in the Health Area of Ferrol, La Coruña, Spain, with deliveries that were initiated with prostaglandin induction. The patients were divided into two cohorts, depending on the synthetic prostaglandin administered (misoprostol vaginally or dinoprostone in intravaginal device). The Mann-Whitney U test was used to compare the two groups. For qualitative variables, the total number and percentage were described and compared with Pearson's 2 test. RESULTS: A total of 508 patients undergoing labor induction were analyzed. No differences were found in the indications for induction of labor between one group and the other, although the indication for misoprostol in patients with chronologically prolonged pregnancy (63%) and for dinoprostone in premature rupture of membranes (49%) stood out. In relation to perinatal outcomes, an Apgar of less than 7 at 5 minutes was recorded in 2 patients treated with dinoprostone and 1 with misoprostol; as well as an umbilical arterial pH of less than 7.10 in 8 patients treated with dinoprostone and 7 with misoprostol. CONCLUSIONS: The data reported here suggest that both prostaglandins achieve a similar rate of onset of labor, although dinoprostone appears to reduce the time to onset of labor in women indicated for induction.

Effect of propofol on proliferation, invasion and migration of human melanoma cells and role of COX-2/PGE2/MMP signaling pathway / 中华麻醉学杂志

Objective:To evaluate the effect of propofol on proliferation, invasion and migration of human melanoma cells and role of cyclooxygenase-2 (COX-2)/prostaglandin E2 (PGE2)/matrix metalloproteinase (MMP) signaling pathway.Methods:SKMEL-5 cells were cultured in vitro and divided into 4 groups ( n=36 each) using the random number table method: control group (group C), propofol group (group P), COX-2 overexpression group (group COX-2), and COX-2 overexpression plus propofol group (group COX-2+ P). Propofol at the final concentration of 60 μmol/L was added in group P. The COX-2 overexpression plasmid pcDNA3.1-COX-2 was transfected into SKMEL-5 cells in group COX-2 and group COX-2+ P, and propofol at the final concentration of 60 μmol/L was added in group COX-2+ P.After incubation for 48 h, the cell proliferation rate was determined by CCK-8 method, the cell invasion and migration ability was determined by Transwell assay, the expression of COX-2 in cells was detected by Western blot, the expression of COX-2 mRNA in cells was detected by quantitative real-time polymerase chain reaction, and the concentrations of serum PGE2, MMP-2 and MMP-9 were determined by enzyme-linked immunosorbent assay. Results:Compared with group C, the cell proliferation rate was significantly decreased, the number of cell invasion and migration was decreased, the expression of COX-2 protein and mRNA was down-regulated, and the concentrations of PGE2, MMP-2 and MMP-9 in the supernatant were decreased in group P, and the cell proliferation rate was significantly increased, and the number of cell invasion and migration was increased, the expression of COX-2 protein and mRNA was up-regulated, and the concentrations of PGE2, MMP-2 and MMP-9 in the supernatant were increased in group COX-2 ( P<0.05). Compared with group P, the cell proliferation rate was significantly increased, and the number of cell invasion and migration was increased, the expression of COX-2 protein and mRNA was up-regulated, and the concentrations of PGE2, MMP-2 and MMP-9 in the supernatant were increased in group COX-2+ P ( P<0.05). Conclusions:Propofol can inhibit the proliferation, invasion and migration of human melanoma cells, and the mechanism may be related to inhibition of the COX-2/PGE2/MMP signaling pathway.

INTRODUCTION AND OBJECTIVES: Describe the experience of deliveries in pregnant women with a confirmed diagnosis of COVID 19 by asymptomatic RT-PCR or with mild symptoms and those without the disease, and determine the success rate of vaginal delivery in the induction of labor. METHODS: Retrospective study of patients who had their delivery between 15th April and 03rd of July, 2020 in the San Juan de Dios Hospital. Patients induced with Dinoprostone, Oxytocin or both sequentially were included, and were divided according to COVID 19 status by RT-PCR on their admission process. The group of positive patients was demographically characterized and the data of both groups was determined in relation to the need for labor induction and its success for vaginal delivery. RESULTS: Of a total of 657 births, there were 9.7% (n = 64) of patients with COVID 19, of which 23.4% (n = 15) required labor induction, with a success rate for vaginal delivery of 66.7% (n = 10). Of these patients, 50% received Oxytocin, 40% Dinosprostone and 10% both drugs sequentially. In the negative patients, there were a total of 568 births, with 29.8% (n = 169) of users requiring labor induction. The success rate for vaginal delivery in this group was 72.2% (n = 122); 50% using Oxytocin; 27% Dinoprostone; 14.8% using both; and 8.2% using Cook's Catheter. CONCLUSIONS: We know that the results of this study are limited by the low number of patients included, however, in our experience, we can observe that, in patients with SARS-CoV-2 PCR positive, asymptomatic or with mild disease, it was possible to perform induction of labor according to standard protocols, achieving success rates for vaginal deliveries, similar to patients without the disease.

A comparative study of vaginal misoprostol, dinoprostone gel, foley catheter, extra amniotic saline infusion along with vaginal misoprostol for induction of labor at term

Background: Objective of this study was to study the effect of vaginal misoprostol, dinoprostone gel, foley catheter, extra amniotic saline infusion along with vaginal misoprostol for induction of labor at term on maternal and fetal outcome.Methods: A one-year prospective observational study was conducted in the department of obstetrics and gynecology, SDM College of Medical Science and Hospital, Dharwad. Totally 100 postdated primigravida women with singleton gestation, vertex presentation and intact membrane who were induced with any four methods of induction 1) Tab. misoprostol 25 µg vaginally, 2) Intracervical dinoprostone gel, 3) Foley catheter and 4) Extra amniotic saline infusion along with tab. misoprostol 25 µg vaginally with 25 patients selected in each group, by random allocation technique and included in the study. Outcome measures analysed were the demographic profile, bishop score, induction to delivery interval, mode of delivery, maternal and fetal complications. Statistical analysis was done using SPSS 17 software.Results: Mean induction delivery interval was significant between PGE1 versus foley group (p=0.0034). In this study, 60% patients in dinoprostone group had Vaginal delivery and 72% in the EASI + misoprostol group underwent cesarean section (p=0.0372). NICU admission was maximum with EASI + vaginal misoprostol group and minimum with vaginal misoprostol alone.Conclusions: The groups were comparable with respect to maternal age, bishop score and fetal weight. The vaginal misoprostol group had shortest induction delivery interval. The maximum number of patients in dinoprostone gel group underwent vaginal delivery with a highest cesarean section and NICU admission with the EASI + misoprostol group.

Comparative Study of Vaginal Misoprostol and Intracervical Dinoprostone Gel for Induction of Labour.

Induction of labour is an intervention to artificially stimulate uterine contractions leading to progressive dilation and effacement of cervix. This results in delivery of foetus before the onset of spontaneous labour. Dinoprostone gel and Misoprostol are commonly used drugs for cervical ripening. We wanted to compare the efficacy and safety of Dinoprostone with Misoprostol for cervical ripening and induction of labour in women with unfavourable cervix. METHODSThis is a prospective study conducted among 200 antenatal women who required induction of labour for different indications. 100 patients with an indication for induction were given 25 mcg of intravaginal misoprostol and repeat dose up to a maximum of 3 doses every 4 hours as needed. The other 100 patients were given 0.5 mg of intracervical dinoprostone gel and repeated for a maximum of 3 doses every 6 hours as needed. Progress of labour was monitored. Bishop score was determined. RESULTSPostdatism was the most common cause of induction (45% and 58%) in both the groups. The difference in values of mean induction delivery time in both primipara and multipara was not significant statistically for both the drugs. Study showed that the number of caesarean sections was significantly (p value 0.028) reduced with the use of misoprostol for induction of labour. The most common indication for operative delivery was foetal distress (11% in the misoprostol group and 17% in the dinoprostone group). Maternal and foetal complication rate in both the groups was similar. CONCLUSIONSCaesarean rate was significantly less with intravaginal misoprostol group compared to dinoprostone group. Other factors had no statistical significance. Vaginal misoprostol is thus a better option for induction of labour.

A comparative study of the effect of induction of labour with vaginal misoprostol versus prostaglandin E2 gel on the incidence of pathological cardiotocography tracing

Background: The objective of the present study was to compare the two most commonly used agents for induction of labor-vaginal misoprostol and intracervical dinoprostone gel in terms of the incidence of cardiotocography (CTG) abnormalities and its correlation with fetal distress and fetomaternal outcome.Methods: This is prospective case-control study conducted in department of obstetrics and gynecology, RIMS, Ranchi over a period of 15 months. 112 women requiring induction were randomly assigned to two groups of 56 each, Group M received vaginal misoprostol and Group D received intracervical dinoprostone E2 gel. 56 women with spontaneous labor served as control group. Groups were compared in terms of the incidence of suspicious or pathological CTG tracings, fetal distress, induction to vaginal delivery time, vaginal delivery rates, dose requirements, rate of emergency cesarean.Results: Misoprostol was associated with shorter induction to delivery time (9.54 hours) than dinoprostone gel (13.54 hours), higher vaginal delivery rates (80.35% versus 62.5%), higher delivery rates (73.9%) with single dose itself unlike Group D, where 47.22% required more than one dose. Incidence of suspicious CTG was higher in group M (15.68%) versus 10.25% in Group D. Incidence of pathological CTG was also highest in Group M (7.8%) followed by Group D (2.56%) and Group C (7.8%). Dinoprostone gel lead to failed induction in 25% women, and hence higher caesarean rates.Conclusions: While misoprostol is a better agent for induction when compared with dinoprostone E2 gel in terms of induction-delivery time, higher vaginal delivery rates, less dose requirement, it is associated with greater incidence of non-reassuring/pathological CTG. There was justified improvement in perinatal outcome due to preparedness beforehand with use of CTG.

Evaluation of induction of labour in a tertiary care hospital

Background: The objective is to evaluate the preferred methods for labor induction, including incidence of caesarean section, operative and normal vaginal delivery rate, need for oxytocin augmentation, and Apgar score at 1 and 5 min.Methods: This was a hospital-based study carried out in 110 inductions of labour during the study period. misoprostol 50 mcg was inserted in posterior fornix of vaginal in cases with PROM and intracervical 0.5 mg Dinoprostone for other causes in whom induction was decided. Maternal and neonatal outcomes were observed. collected data were analyzed using SPSS and MS excel.Results: Most preferred methods of induction of labour were observed to be Dinoprostone and Misoprostol, augmentation was done by oxytocin. normal delivery rate was 54% in Dinoprostone gel and 58.3% in misoprostol group. Caesarean and operative vaginal delivery rates were 42.8%, 3% in Dinoprostone gel group and 33.3%, 8.3% respectively in misoprostol group. Mean Apgar scores were observed to be similar in both methods of induction at 1st and 5th minutes.Conclusions: It was found that misoprostol had higher percentage of normal and operative vaginal delivery and need for oxytocin augmentation than Dinoprostone. Neonatal outcome as predicted by Apgar score were similar in both groups.

A prospective randomized comparative study of the efficacy of sustained release vaginal insert versus intracervical gel in primigravidae at term pregnancy

vBackground: Induction of labour is the intentional initiation of labour before spontaneous onset for the purpose of delivery of fetoplacental unit. Failure of induction is responsible for increased incidence of caesarean delivery. This study performed to assess and compare the clinical effects of sustained release vaginal insert versus intracervical gel in primiparous women with term pregnancy in terms of improvement of Bishop’s score, Induction delivery interval, incidence of hyperstimulation, maternal and neonatal outcomes.Methods: A total 100 consecutive term pregnant women who underwent labor induction for fetal or maternal indications were divided randomly into two groups. Group A - sustained release Vaginal insert and Group B - Intracervical gel. Informed consent was taken from each patient.Results: Statistically significant increase in final Bishop’s score (p=0.008) and hyperstimulation (p=0.04) was seen in Vaginal insert group as compared to Intracervical gel group, while there were no statistically significant differences in maternal outcomes, neonatal outcomes and need for oxytocin augmentation in both groups.Conclusions: In this study we found that insert did not improve the induction delivery interval or rate of successful induction, nor did it have any advantage in terms of neonatal outcome although it did improve the Bishops score – Its advantage was in terms of single application, few prevaginal examinations, longer duration of action and immediate retrieval in case of hyperstimulation. Its main drawback remained the maintenance of cold chain without which its efficacy decreases. Another significant observation was the dropout rate of insert (16%).

Comparative evaluation of intravaginal slow release Dinoprostone insert, transcervical foley’s catheter, intracervical Dinoprostone gel for induction of labor in patients with poor Bishop’s score: a randomized control study

Background: Induction of labor is indicated when the continuation of pregnancy poses risk to the mother or fetus. A variety of mechanical and pharmacologic methods are available but the best method of labor induction still remains unknown, study aimed at comparing the efficacy and safety among the two agents: transcervical Foley’s balloon catheter (FBC) and intravaginal slow release Dinoprostone E2 insert (DVI) with dinoprostone gel as control.Methods: A total of 174 patients were randomized into three groups of 58 each (Group A: dinoprostone 10 mg slow release intravaginal insert, Group B: transcervical Foley’s 16 French catheters, and Group C as control: 0.5 mg intracervical Dinoprostone gel. The safety and efficacy was compared among the groups. A p value of < 0.05 was considered statistically significant.Results: The mean insertion to active labor time (in hours) was significantly lower in Group A as compared to Group B (5.88±3.06 versus 13.56±2.8, p < 0.0001). Meantime of insertion to delivery (in hours) was significantly lower in Group A as compared to Group B (10.91±5.24 versus 21.17±2.99, p < 0.0001). The requirement of oxytocin for induction and augmentation in Group A was significantly lower as compared to Group B. Majority of the patients had normal vaginal delivery (NVD) in all the three groups. Regarding safety profile we found that slow-release DVI had more incidence of uterine tachysystole, but none of the cases had any fetal heart rate abnormality. Maternal fever was more in the FBC group, however, neonatal outcomes were comparable in both groups.Conclusions: The study concludes that slow release DVI is better in terms of efficacy as compared to transcervical FBC for induction of labor as assessed by improvement in Bishop score, insertion to active labor time and insertion to delivery time and comparable in terms of safety profile.

Comparison of the Efficacy and Safety of Misoprostol with That of Dinoprostone as a Cervical Ripening and Inducing Agent

Background: Induction of labour is defined as the stimulationof uterine contractions using medical or surgical means prior tospontaneous labor in order to achieve vaginal delivery.Dinoprostone gel has been widely used as cervical ripeningand inducing agent. There has been a growing interest in usingmisoprostol, a prostaglandin E1 analogue, as an alternativeagent for inducing labor. Hence; the present study wasconducted for comparing the efficacy and safety of misoprostolwith that of dinoprostone as a cervical ripening and inducingagent.Materials & Methods: A total of 60 eligible women whorequired induction of labour were admitted. After taking a wellinformed consent; detailed history, general examination andobstetric examination was conducted. Patients who fulfilled theabove criteria were divided in two groups either to receivemisoprostol tablet 25µg every 4 hourly intravaginally upto amaximum of 5 doses or dinoprostone gel 0.5mg intracervicallyevery 6 hourly upto a maximum of 3 doses. IntravenousOxytocin was administered as and when required in eithergroup. A Performa was filled for each patient and at the end ofstudy data collected from these Performa’s was tabulated in amaster chart. Statistical analysis was done using SPSSsoftware.Results: Initial Bishops score in the misoprostol anddinoprostone group was 3.85±1.26 and 3.89±0.97respectively. Change in the Bishops score after single dose ofmisoprostol and dinoprostone was 5.48±1.89 and 5.0±2.05respectively. This result was statistically not significant. 66.67%of patients in the dinoprostone group where as 60% of patientsin the misoprostol group required oxytocin. This difference wasnot statistically significant. Only 5 subjects required 3 doses ofdinoprostone whereas 14 subjects needed 2 doses and 11subjects needed only 1 dose of dinoprostone. There were 5cases of failure of induction in the dinoprostone group ascompared to only 3 cases in the misoprostol group. The resultwas not statistically significant.Conclusion: Both dinoprostone and misoprostol are equallysafe and efficacious in cervical ripening and labor induction.

Comparison of intravenous oxytocin infusion versus intracervical dinoprostone followed after 6 hours by intravenous oxytocin infusion for labor induction in prelabor rupture of membranes: A randomized controlled trial / Philippine Journal of Obstetrics and Gynecology

Background@#A prolonged interval from prelabor rupture of membranes to delivery is associated with an increase in the incidence of maternal and neonatal morbidities and mortality. Various agents have been tested to improve the cervical Bishop score to expedite the delivery of the fetus and lessen the maternal and neonatal complications.@*Objective@#To compare two protocols for labor induction in pregnant women with prelabor rupture of membranes (PROM).@*Population@#Subjects were recruited from the University of Santo Tomas Hospital (Private Division and Clinical Division). Pregnant women with a live, term, singleton fetus, cephalic presentation, a reactive Non stress test, who presented with PROM and a Bishop score of ?5, with no previous Cesarean section, or other uterine surgery.@*Methodology@#This is a two-arm superiority, open label, randomized controlled trial. Pregnant women with a live, term, singleton fetus, cephalic presentation, a reactive Non stress test, who presented with PROM and a Bishop score of ?5, and with no previous Cesarean section or other uterine surgery were randomly assigned to receive either intravenous (IV) oxytocin infusion or intracervical dinoprostone 0.5 mg gel followed 6 hours later by IV oxytocin infusion.@*Results@#Vaginal delivery within 24 hours of labor induction increased significantly with intracervical dinoprostone gel followed by IV oxytocin infusion (87% versus 61%; RR: 1.43; 95% CI: 0.99 – 2.06; P<0.044). Comparable result was observed for nulliparous women included in the study population. The time interval from labor induction to active phase was significantly shorter in the dinoprostone-oxytocin group than in the oxytocin alone group (2.4 ± 2.1 versus 6.3 ± 1.4 hours; p<0.001). The time interval from labor induction to delivery was also significantly shorter in the dinoprostoneoxytocin group (6.3 ± 1.5 versus 10.4 ± 1.4 hours; p<0.000). Cesarean delivery rates were statistically similar in the dinoprostone-oxytocin and oxytocin alone groups (17% versus 40%; p=0.102). The neonatal outcomes were comparable in both groups, except for birth weight.@*Conclusion@#Intracervical dinoprostone 0.5 mg gel followed 6 hours later by an oxytocin infusion in term women presenting with PROM and an unfavorable cervix (Bishop Score of 5 or less) was associated with a higher rate of vaginal delivery within 24 hours, shorter time interval from labor induction to active phase of labor, and shorter time interval from labor induction to delivery, and no difference in maternal and neonatal complications was observed compared with oxytocin infusion alone.

Comparative study to evaluate the efficacy and safety of oral Mifepristone versus intracervical Dinoprostone gel for induction of labour and their effects on fetomaternal outcome

Background: Mifepristone and Dinoprostone are used in inducing labour in pregnancy by acting as cervical ripening drugs. A randomized case control study to evaluate the efficacy, safety and fetomaternal outcome of induction of labour with oral Mifepristone and intracervical Dinoprostone gel was done.Methods: About 300 patients were included after taking informed consent. 150 patients were placed in each group A and B. In group A patients received 200 mg oral Mifepristone tablet and in group B 0.5 mg Dinoprostone gel was given intracervically and 2nd dose was repeated after 6 hours later if adequate uterine contractions were not achieved. A detailed analysis was carried out in both groups regarding efficacy and safety of drugs in terms of necessity of augmentation of labour with oxytocin, induction to delivery interval, fetal outcome in terms of NICU admission.Results: 59.33% cases in Mifepristone group and 72% case in Dinoprostone group required augmentation with oxytocin. Mean induction delivery interval in Mifepristone group in primigravida was 17.998±1.128 hrs and mean induction delievery interval in multigravida was 11.648±1.112 hours. 88% cases in mifipristone group and 80% cases in Dinoprostone group delivered vaginally. NICU admission was 1.33% in Mifepristone group and 2.66% in PGE2 gel group.Conclusions: Mifepristone when compared with intracervical Dinoprostone gel, acts as a better cervical ripening agent and requires lesser need for Oxytocin augmentation. Though, mean induction delivery interval was more with Mifepistone, the incidence of successful vaginal delivery was higher as compared to Dinoprostone.

Induction of labor in women with unfavourable cervix: comparison of efficacy of intracervical Foley catheter with PGE2 gel

Background: The aim of our study was to compare the efficacy, safety and patient’s satisfaction of intracervical Foley catheter with intracervical dinoprostone gel (PGE2 gel) for cervical ripening for successful induction of labor.Methods: Prospective study was conducted in Department of Obstetrics and Gynaecology, M P Shah Medical College, Jamnagar, Gujarat. 317 women with term pregnancy with bishop score of less than 4 with various indications for induction were included. Intracervical foley catheter was kept in 162 women for cervical ripening (group A) while intracervical PGE2 gel was kept in rest 155 women (group B).  The change in the bishop score, progress of labor, adverse effects and outcome of labor along with the patient’s satisfaction were assessed.Results: With regard to the obstetrical parameters, the two groups were comparable with respect to maternal age, gestational age, parity, indication for induction and initial bishop score. At 12 hours, both the groups showed significant improvement in bishop score, 5.2±1.81 and 4.8±1.76 in Foley catheter and PGE2 gel respectively. Mean induction to delivery interval was 18.8±5.5 in group A and 17.9±5.3 in group B, which was statistically insignificant.  No significant differences in side effects, mode of delivery and APGAR score were noted in both the groups. However, the incidence of hyperstimulation and tachysystole was higher in PGE2 gel group.Conclusions: This study shows that both Foley catheter and dinoprostone gel appear to be equally effective agents for cervical ripening. Infect foley catheter is cheap, causes less fetal distress and is safer than PGE2 gel.

Effect of single-chamber balloon combined with dinoprostone suppository on cervical ripening induced by full-term maternal delivery / 中国基层医药

Objective@#To investigate the effects of single-chamber balloon combined with dinoprostone suppository on the progestation of the cervix in full-term maternal delivery.@*Methods@#From January 2017 to December 2018, 120 cases of full-term maternal women admitted to the Central Hospital of Yiwu were selected.According to the random number table method, all women were divided into control group (60 cases) and observation group (60 cases). The control group was given a single-cavity balloon to promote cervical ripening.The observation group received single-chamber balloon combined with dinoprostone to promote cervical ripening.The effects of maternal cervical ripening were observed.@*Results@#The total effective rate of maternal cervical ripening in the observation group (95.00%) was significantly higher than that in the control group (81.67%), and the difference was statistically significant (χ2=6.135, P<0.05). The differences of maternal postpartum hemorrhage and neonatal asphyxia rate were not statistically significant (t=1.684 , χ2=2.563, all P>0.05). The total maternal labor [(5.8±2.1)h] in the observation group was significantly shorter than that in the control group [(7.6±2.5)h], the difference was statistically significant (t=3.126, P<0.05). The vaginal delivery rate (95.00%) of the observation group was higher than that of the control group (73.33%), the difference was statistically significant (χ2=5.342, P<0.05). Before implanting the balloon and balloon combination, the Bishop score between the two groups had no statistically significant difference (t=3.623, P>0.05). After the balloon and balloon combination were taken out, the Bishop score of the maternal cervix[(8.6±1.5)points] in the observation group was higher than that in the control group [(7.2±1.3)points], and the difference was statistically significant (t=4.354, P<0.05).

Objective To investigate the effects of single-chamber balloon combined with dinoprostone suppository on the progestation of the cervix in full-term maternal delivery.Methods From January 2017 to Decem-ber 2018,120 cases of full-term maternal women admitted to the Central Hospital of Yiwu were selected.According to the random number table method ,all women were divided into control group (60 cases ) and observation group (60 cases).The control group was given a single-cavity balloon to promote cervical ripening.The observation group received single-chamber balloon combined with dinoprostone to promote cervical ripening .The effects of maternal cervical ripening were observed.Results The total effective rate of maternal cervical ripening in the observation group (95.00%) was significantly higher than that in the control group (81.67%),and the difference was statisti-cally significant (χ2 ＝6.135,P＜0.05).The differences of maternal postpartum hemorrhage and neonatal asphyxia rate were not statistically significant ( t ＝1.684 ,χ2 ＝2.563,all P＞0.05).The total maternal labor [( 5.8 ± 2.1)h] in the observation group was significantly shorter than that in the control group [(7.6 ±2.5) h],the differ-ence was statistically significant (t＝3.126,P＜0.05).The vaginal delivery rate (95.00%) of the observation group was higher than that of the control group (73.33%),the difference was statistically significant ( χ2 ＝5.342,P＜0.05).Before implanting the balloon and balloon combination ,the Bishop score between the two groups had no statis-tically significant difference (t＝3.623,P＞0.05).After the balloon and balloon combination were taken out ,the Bishop score of the maternal cervix [(8.6 ±1.5)points] in the observation group was higher than that in the control group [(7.2 ±1.3)points],and the difference was statistically significant (t＝4.354,P＜0.05).The incidence of adverse reaction of the observation group (6.67%) was lower than that of the control group (13.33%),the differ-ence was statistically significant between the groups ( χ2 ＝3.821,P＜0.05).Conclusion Compared with simple single-chamber balloon,single-chamber balloon combined with dinoprostone suppository has more significant effect on the maternal ripening of the cervix ,it can improve the vaginal delivery rate and maternal cervical Bishop scores , effectively reduce the maternal total labor ,and reduce the incidence of maternal adverse reactions.

Comparative Study Of Pre- Induction Cervical Ripening With Foley And Dinoprostone

Background: To compare the efficacy for pre–induction cervical ripening with Foley catheter vs PGE2 in elective induction Materials and Methods: The study group consisted of 100 antenatal women admitted for safe institutional delivery and who required pre–induction cervical ripening. Labour was induced in 50 women with Foley catheter and remains 50 women with similar inclusion criteria with 0.5gms Dinoprostone gel and efficacy of both method is compared. Results: The induction to vaginal delivery interval in the Foley group was 9.8hrs and 12.5hrs with the Dinoprostone group. Rate of vaginal deliveries was 78% in Foley group and 64% in Dinoprostone group respectively. Caesarean delivery rate was 22% and 36% in Foley group and Dinoprostone group respectively maternal side effects tachysystole, vomiting, diarrhoea, post pasture haemorrhage higher with Dinoprostone groups. Conclusions: Foley catheter I safer, easier, cheaper, effective method of pre–induction cervical ripening.

A Clinical Trial Comparing Intra Vaginal Misoprostol (PGE1) And Intra Cervical Dinoprostone ( Pge2 ) For Cervical Ripening

In the present trial, Misoprostol(PGE1) and Dinoprostone(PGE2) are compared for their efficacy in pre - induction cervical ripening. After informed consent, 100 patients were randomized to receive either Dinoprostone gel int0.5mg inracervically or Misoprostol tablet 25 mcg intravginally. After 8 hrs, change in Bishops score recorded. During the study it is found that, change in Bishops score is significantly more and induction to delivery interval is significantly less in Misoprostol group. The incidence of side effects is similar in both the groups. It is concluded that a single dose of intravaginal Misoprostol is an efficacious, convenient and inexpensive medication for ripening the unfavourable cervix.

Prognostic effect of intrauterine pregnancy induced by different methods of cervical ripening / 中国基层医药

Objective@#To investigate the effect of different cervical ripening methods on induction of labor in term pregnancy.@*Methods@#160 cases of labor induction of full-term pregnancy primipara were selected as the research subjecs.According to the different methods of cervical ripening, they were divided into two groups.The observation group (n=80) underwent dinoprostone suppositories induced labor, the control group (n=80) received intravenous infusion of small dose of oxytocin.The cervical Bishop score, cervical ripening effect, induction of labor, mode of delivery, neonatal outcome were observed in the two groups.@*Results@#Before treatment, the Bishop scores of the two groups had no statistically significant difference (t=0.436, P>0.05). After treatment for 24h, the Bishop score of the observation group was (8.3±2.6)points, which was higher than (5.9±2.0)points of the control group (t=6.544, P<0.05). In the observation group, the total effective rate of cervical ripening was 95.0%, which was higher than 66.2% of the control group (Z=-5.716, P<0.05). The duration of labor in the observation group was (12.6±4.5)h, which was significantly shorter than (21.7±7.8)h in the control group (t=9.039, P<0.05). The total labor, postpartum hemorrhage volume had no statistically significant differences between the two groups (t=2.298, 1.102, all P>0.05). In the observation group, 66cases (82.5%) were vaginal delivery, 14cases(17.5%) were cesarean section, those were 49cases(61.2%) and 31cases(38.8%) in the control group.The delivery mode of the observation group was significantly better than that of the control group(χ2=8.935, P<0.05). There were no statistically significant difference between the two groups in neonatal birth weight and postnatal 1min and 5min Apgar scores (all P>0.05).@*Conclusion@#Parturient with dinoprostone suppositories full-term pregnancy abortion can improve the cervical Bishop score and cervical ripening effect, improve the quality of delivery, it is better than oxytocin, and worthy of clinical application.

Expression of PGE2 and COX-2 in colorectal cancer and the clinical significance / 中华普通外科杂志

Objective To investigate the expressions of PGE2 and COX-2 between colorectal cancer tissue and normal colorectal mucosa tissue,and its relation to clinical pathology and significance.Methods 115 colon cancerous tissues and 69 normal colon tissues were collected in our hospital from Jan 2010 to Sept 2011.Immunohistochemistry was used to detect the PGE2 and COX-2 expression in both of the colorectal cancer and normal tissues.Results Positive expressions of PGE2 and COX-2 were 87.8％ (101/115) and 80.9％ (93/115) in the colorectal cancer tissue,and 8.7％ (6/69),21.7％ (15/69) in normal colorectal mucosa tissue respectively (x2 =110.96,62.194,all P ＜ 0.05).Expressions of PGE2 and COX-2 were closely associated with,tumor invasion,differentiation,lymph node metastasis and TNM stage (P ＜ 0.05).The Spearman rank correlation analysis indicated that the PGE2 and COX-2 expressions in tissues were closely correlated (r =0.987,P ＜ 0.05).Survival rate of the patients in both negative expressions of PGE2 and COX-2 (63.6％) were higher than that of both positive expressions (37.8％,P ＜ 0.05).Conclusion High PGE2 and COX-2 expressions in colorectal cancer tissues predicts poor patients' survival.
