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.

Comparison of the efficacy, safety, acceptability and fetomaternal outcomes of combination of mifepristone and foley’s catheter with foley’s catheter alone in induction of labour in term pregnancies with previous lower segment caesarean section

Background: Objective of the study was to compare the efficacy, safety, acceptability, fetomaternal outcomes of combination of mifepristone and Foley’s catheter with Foley’s catheter alone in induction of labor in term pregnancies with previous Lower segment caesarean section (LSCS).Methods: This was a prospective study of 36 women induced with mifepristone and foley’s catheter and 36 women induced with foley’s catheter alone at 37 weeks to 41+6 weeks with previous LSCS.Results: Mean bishop score on admission in combined group (2.44) was comparable with that of foley’s alone group (2.91, p=0.888). Mean Bishop score (BS) after foley’s expulsion in group A and group B was 7.46 and 6.33 respectively, which was statistically significant (p<0.001). In group A 69.5% of women delivered vaginally compared to 52.2% in group B which was comparable (p=0.230). Mean induction to delivery interval was significantly short in combination group (15.5±1.3 hours versus 20.8±1.07 hours, p=0.003). 50% women in group A required oxytocin for induction/ augmentation of labour as compared to 77.8% in group B (p=0.02). Failed induction was statistically higher in group B (p<0.05). No difference was found with regards scar dehiscence, scar rupture, Postpartum hemorrhage (PPH), wound infection, puerperal pyrexia, Meconium stained liquor (MSL), fetal distress, mean birth weight, 1 and 5 minutes Appearance, pulse, grimace, activity, and respiration (APGAR) score, neonatal outcome, hospital stay.Conclusions: Priming with mifepristone before insertion of foley’s catheter results in significant change in BS signifying that combination promotes early cervical ripening as compared to foley’s catheter alone. Mifepristone plays significant role in cervical ripening, reduces induction to delivery interval, oxytocin requirement and failed induction.

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.

A comparative study of intracervical foley’s catheter with oxytocin and vaginal misoprostol for induction of labour

Background: Induction of labour implies stimulation of uterine contraction before spontaneous onset of labour with or without ruptured membranes. Aim of this study was to compare the efficacy and safety of intracervical Foley’s catheter with oxytocin and vaginal misoprostol for labour induction at term.Methods: A total 100 term pregnant women were chosen with bishop score <6 and divided into two groups: Foley’s catheter with oxytocin (Group A) and vaginal misoprostol (Group B). In Group A, a 16 F Foley’s catheter introduced beyond internal os and traction applied every 4 hourly to check for expulsion with simultaneous oxytocin infusion (2 mU/min up to 32 mU/min). In Group B, 25 mcg misoprostol administered every 4 hourly (maximum 6 doses or 150 mcg). Data analysed using SPSS software 20.0. A p value <0.05 was considered statistically significant.Results: No statistical difference found between demographic variables between two groups. Both primigravida and multigravida had poor pre-induction bishop score in both groups. Foley’s catheter (80%) and misoprostol group (96%) had successful induction and was statistically significant (p<0.05). Foley’s catheter took more time from induction-delivery both in primigravida and post-dated pregnant women. The rate of cesarean in Foley’s catheter group was high (62.5%) including 33% cases with failed induction. Foley’s catheter had less maternal and neonatal complications, less NICU admission as compared to misoprostol (p>0.05).Conclusions: Misoprostol was found better for successful induction, decreases induction-to-delivery interval and increases vaginal delivery as compared to Foley’s catheter but it needs constant supervision in view of hyperstimulation and tachysystole.

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.

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.

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.

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.

Efficacy of vaginal Misoprostol versus transcervical Foley’s catheter and vaginal Misoprostol in induction of labor

Background: The objective is to compare the efficacy of vaginal Misoprostol versus transcervical Foley’s catheter and vaginal Misoprostol.Methods: A prospective study analyzing the comparative efficacy of intravaginal instillation of Misoprostol in two groups (tablet Misoprostol 50mg alone and combination of intracervical Foley’s catheter and tablet Misoprostol 50mg) carried out in the labour room on 300 subjects (150 subjects in each group), from May 2013 to November 2015.Results: The common gestational age at the time of induction was 36-40 weeks and the most common indication was premature rupture of membrane. In both the groups, most of the cases delivered within 12 hours. present results show that statistically significant number of cases delivered vaginally within 12 hours with the group using Misoprostol plus Foley’s catheter as compared to the group using Misoprostol alone. Cesarean section rate was 12.67% in Misoprostol group and 10.67% in Misoprostol plus Foley’s catheter group. Incidence of failure of induction was similar in both the groups. The incidence of babies with Apgar score less than 8/10 at 5 minutes and incidence of early neonatal death were similar in both the groups.Conclusions: Addition of intracervical Foley’s catheter to vaginal Misoprostol for induction of labor in subjects with unfavorable cervices reduces the Induction-Delivery interval without added side effects or complications to the mother and fetus.

Objective: To compare the effectiveness of transcervical Foley catheter - oxytocin with oxytocin alone for labor induction in term pregnancies. Design: Case-control study. Setting: Hospital Central "Dr. Urquinaona", Maracaibo, Venezuela. Participants: Pregnant women undergoing cervical ripening and labor induction were randomly assigned to be treated with transcervical Foley catheter - oxytocin (group A) or oxytocin alone (group B). Main outcome measures: General characteristics, interval between beginning of induction and delivery, vaginal birth rate, maternal complications, perinatal variables, and adverse effects were evaluated. Results: There were no significant differences between groups in general characteristics (p = ns). Patients of group A showed a shorter interval between the beginning of induction and delivery compared with patients in group B (p < 0.05). There was no significant difference in vaginal birth rate between groups (p = ns). Newborns of both groups had similar mean values of Apgar scores at 1 minute and 5 minutes (p = ns). The most common adverse effect in both groups was nausea, but there were no significant differences between groups in frequency of adverse effects (p = ns). Conclusions: Use of transcervical Foley catheter - oxytocin shortened the interval between beginning of induction and delivery compared with oxytocin alone, with similar incidence of maternal and perinatal adverse effects.

Advantages of foley catheter for nephrostomy tube after minimally invasive percutaneous nephrolithotomy / 中南大学学报(医学版)

Objective:To assess the advantages and nursing experience of foley catheter for nephrostomy tube after minimally invasive percutaneous nephrolithotomy (mPCNL).Methods:From October 2015 to April 2016,the clinical data of 137 patients,who were diagnosed with upper urinary tract calculi and need to perform mPCNL,were collected and randomized into 2 groups:a foley catheter group (research group,n=69) and a normal nephrostomy tube group (control group,n=68).The patients in research group used foley catheter for nephrostomy tube,while those in the control group used normal nephrostomy tube.Bleeding volume,the days of bleeding,pipes shedding and pain degree were compared,and the experience of the nursing process was summarized.Results:The bleeding volume,the days of bleeding in the research group were significantly lower than those in the control group (both P＜0.01).The pipes shedding rate in the research group were lower than that in the control group (P＜0.05).There was no significant difference in postoperative pain scores between the 2 groups (P＞0.05).There was no other complications and discomfortable symptoms in the experimental group.Conclusion:The use of foley catheter for nephrostomy tube after mPCNL is safe,and it can decrease the bleeding volume and pipes shedding rate.It doesn't increase the patient's postoperative pain and can reduce the difficulty and risk for postoperative nursing.

Humble Foley's catheter to the rescue in a case of T-tube insertion: a case report / 대한마취과학회지

The Montgomery T-tube poses a challenge to anesthesiologists because of loss of anesthetic gases through the open proximal end of the vertical limb and lack of standard anesthesia circuit connectors. Here, we present a case of a 25-year-old woman with a reported history of accidental strangulation 18 months previously. The patient had a metallic tracheostomy tube in situ due to the development of tracheal stenosis. Computed tomography showed significant narrowing in a 7–8-mm segment, 2 cm proximal to the tracheostomy tube in situ. She was scheduled for tracheal reconstruction surgery and T-tube insertion due to persistent subglottic stenosis. In this case, the Foley's catheter, which was inserted into the glottis orally, not only aided easy insertion of the T-tube into the trachea through the tracheal stoma, but also enabled us to stop the loss of anesthetic gases through the proximal vertical limb of the T-tube.

Preventing Effect of Different Dosages of Progynova in Intrauterine Adhesions After TCRS Under Laparoscope / 医药导报

Objective To explore the effect of different dosages of progynova in preventing intrauterine adhesions after transcervical resection of septum ( TCRS) under laparoscope. Methods Clinical data of 213 TCRS patients under laparoscope were retrospectively analyzed, and these cases were divided into four groups according to the dosages of progynova. Except for group A (n=26), group B, C, D were given 4,6,8 mg.d-1 of progynova.Endometrial thickness, menstrual blood volume, incidence rates of residual septal and intrauterine adhesions, rate of adverse effect, pregnancy rate after operation and rate of spontaneous abortion were compared among the four groups. Results The incidence rate of residual septal in group A, B, C, D was 11.5%, 6.9%, 6.0% and 6.3%, respectively.Incidence rate of intrauterine adhesions after operation was 46.2%, 12.5%, 9.0% and 4.2%, respectively.The pregnancy rate in group A, B, C and D was 30.8%, 59.7%, 58.2% and 60.4%, respectively. There were significant differences between group A and the other groups(all P<0.05).The high dose of progynova(8 mg.d-1) significantly increased endometrial thickness ( P<0. 05 ) and menstrual blood volume ( P<0. 05 ) . But the incidence rates of gastrointestinal tract reaction, hepatic damage and vaginal spotting in the high dose group of progynova increased obviously( P<0.05) . Conclusion Progynova is a safe and effective drug in preventing intrauterine adhesions after TCRS. It can effectively prevent intrauterine adhesions, increase pregnancy rate and improve pregnant outcome.

Intracervical foley catheter balloon versus oxytocin infusion as pre-induction cervical ripening agent in live term pregnancies with unfavorable cervices / Philippine Journal of Obstetrics and Gynecology

OBJECTIVE: The purpose of this study was to evaluate the effectiveness and safety as well as maternal and fetal outcome of intracervical Foley catheter balloon versus oxytocin infusion as pre-induction cervical ripening agents in live term pregnancies with unfavorable cervices.METHODS: Forty-two patients who fulfilled the induction criteria were randomized to 2 groups. Group 1= intracervical balloon catheter and Group 2= oxytocin infusion. Both groups were compared as to: insertion/infusion to active phase interval, induction to delivery interval, uterine hyperstimulation, pain intensity, delivery and fetal outcome. Analysis of data collected was done using Indepedent T-test.RESULTS: Statistical analysis showed no significant difference as to insertion/infusion to active phase interval (p 0.814) and induction to delivery interval (p 0.264) between the balloon and oxytocin groups. By percentage comparison, both groups have comparable results in the mode of delivery, likelihood of cesarean section and good fetal outcome. Statistical significance was observed with regards to absence of uterine hyperstimulation (p 0.036) and absence of pain (p 0.000) in favor of the balloon group.CONCLUSION: By percentage comparison, intracervical Foley catheter balloon and oxytocin were both effective and safe in achieving cervical dilatation. The Foley catheter showed statistical significance in terms of absence of uterine hyperstimulation and pain. Foley catheter is readily available and affordable. It may be considered as a good alternative to oxytocin.

Effects Foley catheter placement to expedite the process of delivery.

Background: Finding a suitable procedure in cases requiring termination of pregnancy without having a ready cervix to induction of labor, is a considerable problem in midwifery. The aim of this study was to compare the effect of Foley catheter placement with oxytocin to expedite the process of delivery. Methods: This is an interventional study. In this study, patient information including age, gestational age, residence place, education, induction time, induction complications, cesarean delivery after induction were entered in a checklist. Collected data analyzed by descriptive and analytical statistical methods in SPSS.16. Results: In this study 100 pregnant women were enrolled in two equal size groups, case (receiving a Foley catheter and oxytocin) and control (receiving oxytocin), each with 50 patient. The mean age of cases was 24.7±3.4 years and controls were 23.9±2.3 years and the most prevalent age group in both was 20-30. In cases 14 % and in controls 12 % were with underlying disease and 14% of women in case group and 24% of women in control group had narrowing of vaginal canal. The most common reason for starting induction in cases was lack of progress in labor and in controls dilation of delivery. The mean gestational age in cases was 39.9±1.9 and in control 39.2±1.8 weeks. In relation to dilatation progress, results showed that in cases individuals reached to full dilatation early and this difference was, in cases 14 % and in controls 22% of deliveries are ended to caesarean. 14% of deliveries in cases and 22% in controls are ended to Caesarean section. There was no significant difference between two groups in birth time Apgar score and 5 minutes after birth time. Conclusions: Results showed that, Foley catheter could significantly reduce induction time significantly and resulted to faster labor but did not reduce the rate of caesarean.

Clinical Outcome of Foley Catheter Balloon Versus Prostaglandins in Labor Induction of Late Pregnancy：A Meta Analysis / 医药导报

Objective To compare the efficacy and safety of Foley catheter (FC) and prostaglandins (PG) for cervical ripening used in labor induction of late pregnant women with unfavorable cervix. Methods Several databases including Cochrane Library,Embase,PubMed,Elsevier,Wanfang Medical Database, CNKI, VIP were searched for collecting the related literatures according to criteria for inclusion and exclusion.Meta analysis was performed by applying software Review Manager 5.2. Results Thirty randomized controlled trials were included.The FC group presented significantly lower risk of excessive uterine contraction [OR= 0.38,95%CI(0.19,0.75),P<0.05] than the PG group.There was no significant difference between the two groups in terms of Cesarean section rate, vaginal delivery rate, Bishop score improvement, duration of induction to delivery, neonatal birth weight, or in neonatal outcome. Conclusion This study shows that FC has good promoting effect of cervical maturity and maternal￣ neonatal outcomes, and rarely produces excessive uterine contraction.It is safe and equally effective as PG does.The approach is easy to operate and worth to apply in clinical use.

Comparison of the Efficacy and Safety of Carboprost and Foley Catheter for the Expand Cervix before Hys-teroscopic Electric Resection / 中国药房

OBJECTIVE:To observe the efficacy and safety of carboprost and Foley catheter for the expand cervix before hys-teroscopic electric resection. METHODS:80 patients with hysteroscopic operation were randomly divided into research group and control group. Research group was placed inside the vagina carboprost 1 mg 30 minutes before operation;control group was placed inside the Foley catheter 12 hour before operation. The relaxation degree of the cervix,average operative time,preoperative pain, postoperative morbidity and incidence of adverse reactions in 2 groups were observed. RESULTS:There were no significant differ-ences in the relaxation degree of the cervix,postoperative morbidity and incidence of adverse reactions between 2 groups(P>0.05). The average operative time and preoperative pain in research group were significantly better than control group,the differ-ence was statistically significant(P<0.05). CONCLUSIONS:Carboprost and Foley catheter have good efficacy and safety for ex-pand cervix before hysteroscopic electric resection,however,carboprost is better than Foley catheter in terms of average operative time and preoperative pain.
