Randomized and controlled trial to determine safety and efficacy of Foley’s catheter and PGE2 gel for induction of labor

Background: The goal of obstetrics is a pregnancy that results in a healthy infant and a healthy mother. During medical or obstetrics complications of pregnancy, cervical ripening and induction of labor are often required. Different methods are available for that. Aims and Objectives: Randomized and control trial has been conducted to determine safety and efficacy of Foley’s catheter and prostaglandin E2 (PGE2) gel for induction of labor. Materials and Methods: Randomized and controlled trial has been conducted on 200 study participant who fullfield inclusion criteria in Department of Obstetrics and Gynaecology, GMERS Medical College, Sola during the period of July 2017–July 2019. Statistical analysis was done by descriptive statistics and qualitative method. Results: Both groups cerviprim and Foley’s catheter are comparable for cervical ripening for induction of labor in terms of safety and efficacy as there was no statistically significant observation for obstetric and perinatal outcome. Conclusion: Foley’s catheter is equally dependable method for cervical ripening for induction of labor as cerviprim gel as it is cost effective and easily available.

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.

Parto pré-termo espontâneo sem rotura de membranas: intervenções para evitar o parto pré-termo / Spontaneous preterm birth without rupture of membranes: interventions to prevent preterm birth

A prematuridade é uma síndrome com múltiplos fatores de risco e cuja causa permanece desconhecida, mas, independentemente da etiologia, a parturição converge para uma via final comum de esvaecimento, dilatação e encurtamento do colo uterino. Do ponto de vista hormonal, o responsável por esse processo é a progesterona. A prevenção de quadros de prematuridade pode basear-se em tratamentos medicamentosos como a administração diária de comprimidos de progesterona; intervenções cirúrgicas para a contenção da cérvice uterina com fios inabsorvíveis mantidos até o termo, a cerclagem cervical; e o pessário cervical, dispositivo de silicone que envolve e inclina o colo uterino, evitando sua abertura. Para propor qualquer intervenção profilática ou terapêutica, a avaliação ultrassonográfica via transvaginal no segundo trimestre gestacional desempenha papel crucial. Apresentamos neste terceiro e último artigo da série sobre parto pré-termo espontâneo as intervenções terapêuticas e o rastreamento do colo uterino.(AU)

Preterm birth is a syndrome with multiple risk factors, with unknown etiology. Parturition converges to a final path with uterine cervix effacement, dilation and shortening and progesterone is the hormone responsible for this process. Preterm birth prevention relies on daily administration of progesterone pills; cerclage as a surgical intervention; or cervical pessary, a vaginal silicone device that enfolds and deflects the cervix, avoiding its opening. To propose any of these interventions it is crucial to evaluate the cervix during the second trimester by transvaginal ultrasound. Here, in the third and last article regarding preterm birth without membrane disruption, we present therapeutic interventions and ultrasound screening.(AU)

Comparative study on cervical ripening and labour induction with dinoprostone versus foley’s catheter with extra amniotic saline infusion

Background: Induction of labour is defined as initiation of uterine contractions before spontaneous onset of labour. This observational study compares the effect of prostaglandin E2 (PGE2) and extra amniotic saline infusion (EASI) for pre-labour ripening of unfavourable uterine cervix.Methods: This was a prospective study conducted on 100 pregnant women with gestational age ≥37 weeks during a year period in the department of obstetrics and gynaecology of government TD medical college, Alappuzha, Kerala. The period of study was for one year from June 2002 to July 2003. All patients were divided into two groups. Group-1 contains 47 patients who received intracervical PGE2, (Dinoprostone gel, 0.5 mg). Group-2 contains 53 patients who were induced with EASI. The main outcome variables were the number of subjects with favourable Bishop's score, mode of delivery, maternal complications and neonatal outcomes.Results: Majority of the patients in both the groups were in the age of 21-30 years. There was significant difference in age, parity and gestational age of both groups. In this study it was found significant difference in the occurrence of hyper stimulation among PGE2 and EASI; whereas, there was no significant difference in the occurrence of maternal pyrexia among two groups. High incidence of caesarean section was found in EASI. APGAR score of new born babies was high in labour induced with PGE2.Conclusions: PGE2 and EASI have similar efficacy in induction of labour, but EASI is associated with more side effects. Cost wise EASI is more cost effective than PGE2.

Comparative study of oral mifepristone and endocervical prostaglandin-E2 gel as pre-induction cervical ripening agents in parturition

Background: Intracervical instillation of prostaglandin E2 is a well-known and widely practiced method of pre-induction cervical ripening. Mifepristone, due to its anti-progesterone action has been found to be a potential cervical ripening agent. This study was conducted to compare the safety, efficacy and outcome of these two drugs in pre-induction cervical ripening.Methods: One hundred antenatal women were recruited for the study; 50 in mifepristone arm and 50 in PG-E2 gel arm. Any singleton term pregnancy in vertex presentation with intact membranes and bishop’s score of <4 was included in the study. Any contraindication for vaginal delivery and any contraindication for mifepristone or PG-E2 were considered as exclusion criteria. Participants in the mifepristone arm were given tablet mifepristone 200 mg orally and those in PG-E2 gel group received endocervical instillation of PGE2 gel 0.5 mg, two doses 6 hours apart (if necessary). Induction of labour was considered successful if the parturient delivered within 48 hours of administration of mifepristone or first dose of PG-E2 gel, with or without labour augmentation with oxytocin. Delivery after 48 hours and caesarean delivery were considered unsuccessful induction.Results: There was a significant improvement in bishop’s score in mifepristone group 5.0±1.55 as compared to PG-E2 gel group 3.64±2.14; p value 0.001.Conclusions: Oral administration of 200 mg mifepristone is a safe, effective and convenient alternative to intracervical instillation of prostaglandin-E2 gel for pre-induction cervical ripening.

Parto pré-termo espontâneo sem rotura de membranas: prevalência, fatores de risco e o papel do colo uterino / Spontaneous preterm birth without premature rupture of membranes: prevalence, risk factors and the role of the cervix

Cerca de 15 milhões de prematuros nascem por ano globalmente. Em 2015 ocorreram mais de 4 milhões de mortes de crianças menores de 5 anos, e as complicações da prematuridade são a principal causa de óbito em neonatos. O parto pré-termo é uma síndrome em que múltiplas etiologias convergem para uma via final única, e os fatores de risco mais importantes são antecedente de prematuridade e gestação gemelar. O colo uterino tem a função de manter a gestação desde a concepção até o parto, e seu processo de amadurecimento gera esvaecimento, dilatação e encurtamento, num continuum que pode compreender desde quadros de insuficiência cervical até o parto pré-termo espontâneo sem rotura de membranas. Este primeiro artigo, da série de três, descreve a prevalência da prematuridade, seus fatores de risco e o papel do colo uterino no processo de parturição.(AU)

Around 15 million preterm births happen globally. In 2015 over 4 million deaths in children under 5 years of age died and preterm birth complications is the leading cause in neonates. Preterm birth is a multiple etiology syndrome, in which various causes converge to a single parturition path. The most important risk factors are multiple gestation and obstetrical history of preterm birth. Uterine cervix is responsible for pregnancy maintenance from conception to birth, and its remodeling process generates effacement, dilation and shortening in a continuum that comprises conditions from cervical insufficiency to preterm birth without membrane disruption. This is a first article, of a series of three, describing preterm birth prevalence, risk factors and uterine cervix role in parturition.(AU)

Comprimento de colo uterino ao ultrassom transvaginal como preditor de risco do parto pré-termo espontâneo / Ultrasound cervical lenght predicting risk for spontaneous preterm birth

O encurtamento do colo uterino é parte da via final comum da parturição seja a termo ou pré-termo. A identificação precoce do comprimento cervical encurtado ao ultrassom transvaginal no segundo trimestre gestacional pode atuar como preditor de risco de prematuridade. Desde a década de 1990, vários estudiosos dedicaram-se a estabelecer parâmetros de referência para as medidas de colo uterino entre 16 e 24 semanas e até hoje o limite mais consensualmente aceito é de 25 mm. Especialistas são favoráveis à triagem universal, mas diretrizes internacionais são controversas quanto à investigação em casos sem antecedente de parto pré-termo, além de diversos estudos apresentarem que há custo-efetividade no rastreamento universal. Neste artigo, discutimos criticamente os parâmetros apresentados por estudos históricos e balizadores de conduta, a custo-efetividade e os guidelines internacionais. Propomos ainda uma reflexão ao pré-natalista, sugerindo a individualização da conduta perante os dados de cada gestante específica.(AU)

Cervical shortening is the final path of parturition, regardless if it is term or preterm. Precocious identification of a shortened cervix by transvaginal ultrasound during the second gestational trimester can act as a risk predictor of prematurity. Since the 1990´s decade, numerous studies established reference ranges for cervical length measurement between 16 to 24 gestational weeks and the most accepted cutoff limit is 25 mm. Experts indicate universal screening, however international guidelines are controversial, even in cases without a history of preterm birth, furthermore, many studies demonstrated cost-effectiveness about the universal screening of cervical length in middle gestation. In this article we discuss historical reference ranges, cost- -effectiveness, and international guidelines. We propose critical thinking and suggest individualized management according to specific characteristics of each patient.(AU)

A comparative study of transcervical foley’s catheter with intracervical PGE2 gel for pre-induction cervical ripening

Background: To compare the efficacy of transcervical foley’s catheter with intracervical PGE2 gel for pre -induction cervical ripening.Methods: It was a prospective interventional study conducted between April 2012 to April 2013 in the department of obstetrics and gynecology at L. L. R. M. medical college and S. V. B. P. hospital Meerut. A total of 80 pregnant women of ≥28 weeks of gestation with bishop score less than or equal to 4 and with various indications for induction of labour were randomly allocated to receive intracervical PGE2 gel (Group A) or transcervical foley’s catheter (Group B). Bishop score was repeated after 6 hours by the same person and the results were compared.Results: The groups were comparable with respect to maternal age, gestational age, indications of induction of labour and initial bishop’s score. The intragroup results were calculated by Wilcoxon signed rank test and intergroup results were calculated by Mann Whitney U-test. The change in bishop score in PGE2 group was 3 and in foley’s group was 3.25 after 6 hours of induction (interquartile range of median) which is significant. The mean change in bishops score was 2.65 in PGE2 group and 3.1 in foley’s group after 6 hours of induction and was significant, however the bishop’s score was comparable in both the groups and statistically insignificant.Conclusions: Both foley’s catheter and PGE2 gel are equally effective in pre-induction cervical ripening of cervix.

Use of vaginal misoprostol before endometrial biopsy in premenopausal women: an observational study

Background: It is well-known since long time the beneficial effects of misoprostol particularly as a cervical softening agent in obstetric practice. Keep in view, study aimed to evaluate the efficacy of vaginal misoprostol 400 mcg before endometrial biopsy in premenopausal women.Methods: All the 200 patients were classified into two groups viz. study group (Group I) with 100 patients and control group (Group II) with 100 patients. To Group I patients, 400 mcg of misoprostol was given vaginally, 4 hours prior to the commencement of endometrial biopsy whereas no medication was received by Group II patients.Results: In the present study, the base line cervical dilatation is found to be 5.8±1.3 mm in Group I patients whereas 3.8±0.92 mm in Group II patients which is significantly higher (p<0.05). Only 32 patients in Group I required further dilatation whereas 88 patients in Group II underwent further dilatation. The mean time required for further dilatation in Group I and Group II patients was 42.6±17.4, 64.6±16.8 sec respectively and was significantly higher in Group II patients (p<0.05). Out of 100 patients in Group I, only 2% of patients complained severe pain whereas in Group II 48% of patients experienced intolerable pain and required anesthesia.Conclusions: Vaginal administration of 400 mcg misoprostol 4 hours prior to endometrial biopsy in premenopausal women had a significant effect on cervical resistance and cervical dilatation.

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.

Mifepristone as pre-induction cervical ripening agent: a review article

Induction of labour after the period of viability by any methods medical, surgical or combined, for the purpose of vaginal delivery. The success of induction, to a great extent, depend upon pre-induction cervical status i.e. cervical ripening. So, ripening of cervix prior to induction i.e. pre-induction cervical ripening is one of the important steps for successful induction of labour. There are different methods for cervical ripening like prostaglandins (PGE). However, use of prostaglandins (PGE) and oxytocin as labour inducing agent has its own adverse effects on maternal and perinatal outcome. So, constant efforts are made for the less use of uterotonins. The present review aims to study the efficacy of oral Mifepristone for improvement in Bishop’s score, requirement of additional uterotonics, induction delivery interval, mode of delivery and neonatal outcome. Electronic databases were searched by using keywords ‘Mifepristone, RU486, PGE2 gel, Cervical ripening, Bishop’s score and Induction of labour’ and eleven articles were found from 2009 to 2018 which fulfils our study criteria and thus they were taken for review. Based on all the studies, Mifepristone appears to be effective cervical ripening in comparison to other agents with significant improvement in Bishop’s score, higher vaginal delivery rate, shorter induction delivery interval and good neonatal outcome.

The role of oral mifepristone in pre-induction cervical ripening at term

Background: Planned induction of labor is an established part of modern obstetrics and is used as a definite form of treatment where continuation of pregnancy would be detrimental to the health of mother or fetus. The objective of this study was to evaluate the effect of mifepristone in pre-induction cervical ripening and labor induction.Methods: A total of 200 pregnant women at term with Bishop Score 4 or less were selected for this prospective randomized placebo-controlled study. The sample was equally divided into study group to receive 200 mg of mifepristone and control group to receive placebo orally for 2 days. Bishop score was assessed at every 24 hours interval till patient entered in spontaneous labor or 72 hours after 1st dose. Women who did not enter labor spontaneously, labor induction was planned with per vaginal insertion of prostaglandin (PG) E2 analogue, Dinoprostone gel 2.5 mg or PGE1 analogue Tab. Misoprostol 25 µg.Results: Ninety-six subjects in the study group and eighty-one in the control achieved successful ripening of cervix and the difference was statistically significant. Sixty-eight of study group and thirty-nine of placebo group entered in spontaneous active labor within 72 hours. Requirement of oxytocin as adjuvant treatment was significantly lower in the study group. Nineteen women of study group and fifteen of control group delivered within 24 hours, and eighty-one of study group and sixty-two of placebo delivered in 48 hours. The mean induction delivery interval was 35.53±13.67 hours in the study group, whereas it was significantly prolonged in the placebo group 50.49±20.92 hours. Eighty-two subjects of study group and seventy-eight of the control group delivered vaginally, the differences were statistically not significant.Conclusions: Mifepristone was found to be an effective agent for cervical priming prior to labor induction in women at term and significantly reduces the induction delivery interval compared with placebo.

A comparative study of intra-cervical foley’s catheter and PGE2 gel for induction of labour at term

Background: In cervical ripening, before induction of labour, is needed to increase the success of labour induction, to reduce complications and to diminish the rate of caesarean section and duration of labour. Pharmacological preparations are in widespread use for cervical ripening but are not free from side-effects and complications. Mechanical methods, i.e. the use of Foley’s catheter balloon, though effective have not gained much popularity because of the fear of infection. Therefore, the study has been conducted to prove the efficacy and safety of extra amniotic Foley catheter balloon and to compare it with intra-cervical prostaglandin E2 (PGE2) gel. The objective of the study was to the success of induction of labor depends on the cervical status at the time of induction. For effective cervical ripening both Foley's catheter and PGE2 gel are used. The aim of this study was to compare the efficacy of intra cervical Foley's catheter and intra cervical PGE2 gel in cervical ripening for the successful induction of labor.Methods: A randomized, comparative study was conducted in the department of obstetrics and gynaecology, Civil hospital, B.J. Medical College Ahmedabad, during a period of 8 month from September 2018 to April 2019. 100 patients at term with a Bishop's score ≤5 with various indications for induction were randomly allocated to group F (intra-cervical Foley’s catheter) and group P (PGE2 gel) with 50 women included in each group.Results: The groups were comparable with respect to maternal age, gestation age, indication of induction and initial Bishop's score. Both the groups showed significant change in the Bishop's score, 5.10±1.55 and 5.14±1.60 for Foley's catheter and PGE2 gel, respectively, p <0.001. However there was no significant difference between the two groups. There was no significant difference in the side effects and caesarean section rate in both groups. The induction to delivery interval was 16.01±5.50 hours in group F and 16.85 ± 3.81 hours in group P (p=0.073). Apgar scores, birth weights and NICU admissions showed no significant difference between the two groups.Conclusions: The study shows that both Foley's catheter and PGE2 gel are equally effective in pre induction cervical ripening.

Intracervical PGE2 gel application for cervical ripening and induction of labour: a clinical study

Background: PGE2 gel (cerviprime) not only helps in cervical ripening but also sensitizes the uterine musculature to physiological PGE2 for generation and maintenance of uterine contractions. In the present study the efficacy of PGE2 intracerival gel for ripening and induction of labour has been reported.Methods: This is a randomized prospective study of 80 cases admitted to the labour room during period of 2 years i.e. March 2017 to March 2019 in Department of Obstetrics and Gynecology, KBNIMS, Gulbarga, Karnataka. All patients had clear indications for termination of pregnancy. The initial bishop score determined prior to induction by pelvic examination. Under aseptic precautions PGE2 endocervical gel was instilled. The results analyzed for successful ripening, induction delivery interval, results in primigravida and multigravida with single instillation or reinstallation if required, mode of delivery and maternal and perinatal complications.Results: The present study of 80 cases showed that a single application of intracervical PGE2 gel caused favorable changes in cervix by increasing Bishop score and shortened induction delivery interval with minimal side effects. Successful ripening with single application was achieved in 92.5% of cases (primi 42.5% and multi 50%). Only 6.25% of primi's and 1.25% of multi’s required reinstallation of PGE2 gel. Successful induction was achieved in 47.5% primi's and 50% multi’s i.e. 97.5% cases.Conclusions: The study concludes that single low dose intracervical PGE2 (cerviprime) gel proved to a safe, reliable and effective method for cervical ripening and induction of labour.

Comparative Study between PGE1 Misoprostol and PGE2 Dinoprostone in Preinduction Cervical Ripening

Prostaglandin E2(cerviprime gel), an inducing agent is instilled intracervically or placed high in the posterior fornix of the vagina and may need to be re-in- stilled after 6 h if required. Another alternative is misoprostol (15-deoxy-16- hydroxy-16-methyl prostoglandin E1) which is used in various dosages. Methods: This was a prospective observational study of nulliparous women undergoing labor induction for one year, 100 womens, in a tertiary care center. Participants were then randomly assigned to pre-induction cervical ripening with a dinoprostone vaginal insert (0.5mg) (group I), and with misoprostol (50 microg) intravaginally(group II). Result: From our study observation, maximum patients delivered normal vaginal delivery. Of the vaginal deliveries six (18%) of PGE2 group and five patients(10%) of PGE1 having meconium stained liquor after ARM or spontaneous rupture of membrane, fetal heart was reassuring i.e, no fetal distress was there. The caesarean section rate in both groups nine (18%) and (10%) was statistically insignificant. Mean change in bishop score was also not significant in both groups. Need for oxytocine after 8hrs of induction between both group was significant, 84% in dinoprostone group and 56% in misoprostol group. Gastrointestinal side effects, uterine tacchysystole, uterine hyperstimulation was more common in misoprostol group than dinoprostone group, that is statistically significant. Induction to delivery time was shorter in misoprostol group that is statistically significant. No adverse neonatal outcomes that can directly be related with both drugs. Both agents are equally efficacious in causing cervical repining and almost equal changes in mean bishops. Conclusion: Misoprostol is an excellent labour-inducing agent and can be used liberally for labour induction, unlike PGE2 gel, is comparatively cheaper and is stable at room temperature; thus, it could be an ideal inducing agent in poor resource settings. Local application of misoprostol tablet in posterior vagina is easier method than dinoprostone insertion. Intravaginal insertion of misoprostol tablet is superior to dinoprostone gel in inducing labour and shorter interval between induction and delivery.

Evaluation of isosorbide-5-mononitrate as a cervical ripening agent prior to induced abortion in contrast to misoprostol- a randomized controlled trial

OBJECTIVE: To determine whether vaginal application of 40 mg isosorbide-5-mononitrate (ISMN) has a comparable cervical ripening efficacy to and lesser side effects than 400 µg misoprostol in women scheduled for the first trimester induced abortion using a manual vacuum aspirator (MVA). METHODS: We conducted a prospective randomized open- label study in 70 women at 6–12 weeks of pregnancy at the R G Kar Medical College and Hospital, Kolkata, India, over a period of two years from 2015 to 2017. Forty milligrams of ISMN and 400 µg misoprostol were vaginally applied for cervical priming. The primary outcome measure was the cervical response assessed by the passage of the appropriate and largest sized MVA cannula through the internal os without resistance, at the beginning of the procedure. RESULTS: The base line cervical dilatation was found to be significantly higher in the misoprostol group than in the ISMN group (7.65±1.38 vs. 6.9±1.26 mm; P=0.025, 95% confidence interval, −1.4046 to −0.953). However, when the women were sub-analyzed based on parity, there was no statistically significant difference in the same parameters among the multigravid women. The need for further cervical dilatation was significantly higher in the ISMN group when the primigravid women were compared, although the multigravid women responded favorably to ISMN. CONCLUSION: In the primigravid women, misoprostol appears to exert a higher efficacy as a cervical ripening agent in contrast to ISMN. However, ISMN can be used in multigravid women for the same purpose as in this group, misoprostol did not show any significant improvement in efficacy over ISMN.

Role of Misoprostol in Cervical Ripening for Dilatation and Curettage

Background: Difficulty in cervical dilatation is a hard situation during the procedure of diagnostic dilatation and curettage in some cases. Aim: Aim of the present study was to evaluate the use of Misoprostol for cervical dilatation before D&C in Gynecological cases. Dilatation of cervix is performed as a preliminary step to curette the uterine cavity. Endometrial sampling is often performed either by D&C or by hysteroscopy as an office procedure. Materials and methods: The study was performed at Department of Obstetrics and Gynecology, Victoria Hospital, Visakhapatanam, Andhra Pradesh from June 2018 to May 2019. The study comprised of 150 patients recruited from Gynecology Department with different indications for D&C. Selected cases had a full history of menstrual, Gynec, Obstetric, Personal and Family. A per abdomen and per speculum examination were done to note the Vaginal and Cervical condition. A bimanual pelvic examination was done to estimate size, position and mobility of uterus. In this study, the patients were allocated to receive either oral or vaginal misoprostol or no drug. All the subjects allocated to receive either oral or vaginal Misoprostol were instructed to take the medication at home, the night before the operative procedure. They were given 200 micro grams Misoprostol orally or vaginally 12 hours prior to the procedure. Results: In present study, majority of cases (57.33%) fall in age group of 30-39 years and 34% cases fall in age group of 40-49 years. 83% in Misoprostol group and 90% cases in control group had previous vaginal deliveries. 19% cases in Misoprostol and 20% cases in control group had a prior uterine surgery. Indication for D&C, in majority of cases 66 cases (44%) Heavy menstural bleeding was an indication, followed by Irregular bleeding 53 cases (35.33%), Intermenstural bleeding 29 cases R. Padmaja, P. Rajasekhar. Role of Misoprostol in Cervical Ripening for Dilatation and Curettage. IAIM, 2019; 6(11): 118- 123. Page 119 (19.33%). Cervical dilatation effectively achieved in 62.5% in Nulliparous 69.2% in Primiparous, 94.93% in Multiparous. Conclusion: Both Oral and Vaginal Misoprostol are equally effective in inducing Cervical priming prior to Dilatation and Curettage.

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.
