Shqara RA, Francis YN, Goldinfeld G, Haddad Y, Sgayer I, Lavinsky M, Lowenstein L, Wolf MF. Papaverine prior to catheter balloon insertion for labor induction: a randomized controlled trial. Am J Obstet Gynecol MFM 2024:101388. [PMID: 38825005 DOI: 10.1016/j.ajogmf.2024.101388] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2024] [Revised: 04/17/2024] [Accepted: 05/09/2024] [Indexed: 06/04/2024]
Abstract
BACKGROUND Catheter-balloon insertion is a cervical ripening method of labor induction. Papaverine and its derivatives are musculotropic antispasmodic drugs that directly induce smooth muscle relaxation. Used during childbirth, these drugs have been suggested to shorten the duration of labor. OBJECTIVE We aimed to evaluate the effect of administering papaverine prior to catheter-balloon insertion on changes in Bishop-scores and on the induction-to-delivery interval. STUDY DESIGN This randomized double-blinded placebo-controlled trial was conducted in a single tertiary university-affiliated hospital. Participants were admitted at term for labor induction with an initial Bishop-score ≤6. Participants were randomized to receive papaverine intravenous 80 mg or saline 0.9%, within 30 minutes of Foley catheter-balloon insertion. The co-primary outcomes were the difference in Bishop-score from before catheter-balloon insertion to after removal, and the induction-to-delivery interval. Secondary outcomes included maternal pain and satisfaction-scores, delivery within 24-hours and neonatal outcome. Both intention-to-treat analysis and per protocol analysis were performed. RESULTS In total, 110 women were enrolled. In the intention-to-treat analysis, for the papaverine (N=55) compared to the placebo group (N=55), the median (range) difference in Bishop-score was greater: 7 (range, 4-11) vs. 6 (1-11), p=0.023; and the median range catheter insertion-to-delivery interval was shorter: 21(6-95) vs. 26 (3-108) hours, p=0.031. A higher proportion of women in the papaverine than placebo group delivered within 24-hours: 65.5% vs. 41.8%, p=0.012. Pain and satisfaction-scores, delivery and neonatal outcomes were similar between the groups. Similar results were found in the per protocol analysis. CONCLUSIONS Papaverine prior to Foley-catheter insertion for cervical ripening resulted in improved Bishop-scores and shorter catheter-to-delivery intervals.

The Influence of Oral Drotaverine Administration on Materno–Fetal Circulation during the Second and Third Trimester of Pregnancy. Medicina (B Aires) 2022; 58:medicina58020235. [PMID: 35208558 PMCID: PMC8879767 DOI: 10.3390/medicina58020235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2021] [Revised: 01/31/2022] [Accepted: 02/01/2022] [Indexed: 11/25/2022] Open
Abstract
Background and Objectives: The study aimed to evaluate the effect of the oral administration of drotaverine on maternal and fetal circulation as measured by Doppler sonography in women with a risk of preterm birth. Materials and Methods: The present prospective study was conducted on 34 women with singleton pregnancy at 26–36 weeks of gestation. Doppler flow and pulsatility index (PI) assessments of the umbilical artery, fetal middle cerebral artery, and uterine arteries were performed before and 90–120 min after oral drotaverine administration. Results: There were no statistically significant differences between the Doppler assessment (PI Uma—umbilical artery, MCA—middle cerebral artery, and ltUta—left uterine artery) before drotaverine administration and 90–120 min after oral intake, but there were statistically significant differences between the PI assessment of the rtUta (right uterine artery, 0.55 vs. 0.75, p = 0.05) and the mean of the Uta (0.66 vs. 0.74, p = 0.03). For changes in the CUR (cerebro–umbilical ratio) and % changes in the CUR and mean PI of the Uta, there was no correlation with obstetric history, AFI (amniotic fluid index), gestation week, infertility history, systolic pressure, or diastolic pressure. There was a statistically positive correlation between changes in the CUR and % change in the CUR and body weight and in height. Conclusions: Drotaverine has no statistically significant influence on the MCA and Uma PI. The oral administration of drotaverine has an impact on PI rtUta and the mean PI Uta.

Abstract
RESEARCH QUESTION What is the effect of adding an anti-spasmodic drug to an existing ultrasound-guided manual vacuum aspiration (USG-MVA) protocol to alleviate immediate post-procedure abdominal cramping pain in women treated for early pregnancy loss? DESIGN Double-blind, placebo-controlled, randomized controlled trial conducted between February 2018 and January 2020. Participants were assigned to receive a 1-ml intravenous injection containing 20-mg hyoscine butylbromide (HBB) (n=55) or saline (n =56) as a control immediately before USG-MVA. Primary outcome was reduced abdominal pain after adding a 20-mg dose of HBB to the current pain control regimen. Secondary outcomes were vaginal pain, complications and side-effects, women's pre- and post-procedure psychological state, physiological stress (saliva alpha-amylase) and procedure pain control satisfaction. Two-way mixed ANOVA was used to evaluate the main effects and interactions. RESULTS VAS abdominal pain scores in the HBB group were 16% lower immediately after and 21% lower 2 h after surgery (not statistically significant). Two-way ANOVA indicated that time (F[1108] = 83.41, P < 0.001) was the only significant main effect for reduced abdominal pain after the procedure and vaginal pain score (F[1108] = 180.1, P < 0.0001) but not drug received. No adverse events were reported. No significant difference was found for psychological state, physiological stress and procedure pain control satisfaction between the two groups. CONCLUSIONS Anti-spasmodic drugs can help to reduce abdominal cramping pain associated with USG-MVA; HBB produced an insignificant decrease in abdominal pain score. Further studies with longer acting or larger doses of anti-spasmodic drugs are warranted.

Abstract
This systematic review and meta-analysis assessed the effectiveness and safety of camylofin compared with other antispasmodics (drotaverine, hyoscine, valethamate, phloroglucinol, and meperidine) in labor augmentation. A systematic literature search until March 27, 2018, was performed, and data on the cervical dilatation rate (CDR) and duration of stages of labor reported in 39 eligible articles were analyzed using a random-effects model. CDR was significantly higher (0.38 cm/h, 95% confidence interval (CI) 0.10 to 0.67, p = 0.007), and the duration of the first stage of labor was significantly shorter (- 41.21 minutes, 95% CI, - 77.19 to - 5.22, p = 0.02) in women receiving camylofin than those receiving other antispasmodics for labor augmentation. CDR was significantly higher with camylofin compared with valethamate (0.6 cm/h, 95% CI 0.4 to 0.9, p < 0.0001) and hyoscine (20 mg) (0.5 cm/h, 95% CI 0.1 to 0.8, p = 0.02). The duration of the first stage of labor was significantly shorter with camylofin compared with hyoscine (20 mg) (- 59.9 min, 95% CI, - 117.9 to - 1.8, p = 0.04). However, CDR and the duration of first stage of labor were not statistically different between camylofin and drotaverine groups. The percentage of women having nausea and vomiting, cervical/vaginal tear, and postpartum hemorrhage were comparable with all antispasmodics, whereas tachycardia was least reported in women receiving camylofin (3, 2.07%) than those receiving other antispasmodics. This meta-analysis demonstrated the benefit of camylofin in labor augmentation with a faster CDR and reduction in the active first stage of labor in Indian women.

Abstract
Protein kinases have an important role in signal transduction in the cellular system via protein phosphorylation. RhoA activated Rho-kinases have a pivotal role in the regulation of smooth muscle contraction. ROCK I and ROCK II phosphorylate myosin-phosphatase and myosin-kinase, which induces contraction in the myometrium. Several studies have investigated the affinity of isoquinoline alkaloids (HA-1077, H1152P) to Rho-kinases, and these compounds notably inhibited the Ca2+-independent process. We measured the efficiency of 25 original, newly synthesized isoquinoline derivatives for the Rho-kinase activity using Rho-associated kinase activity assay and determined their effects on the non-pregnant, 20-day pregnant and parturient rat myometrial contraction in vitro. The IC50 values of 11 from among the 25 derivatives were significantly lower on the oxytocin-induced non-pregnant rat uterine contraction compared with Y-27632 and fasudil, although their maximal inhibitory effects were weaker than those of Y-27632 and fasudil. We measured the effects of 11 isoquinoline molecules with significant IC50 values on ROCK II activity. We found two isoquinolines out of 11 compounds (218 and 852) which decreased the active ROCK II level similarly as Y-27632. Then we found that 218 and 852 relaxed the 20th-day pregnant and parturient rat uterus with greater potency as compared with fasudil. The majority of the synthesized isoquinoline derivatives have uterus relaxant effects and two of them significantly suppress the Rho-kinase mediated myosin light chain phosphorylation. Our results may suggest that the isoquinoline structure has a promising prospect for the development of new and effective inhibitors of uterine contractions in preterm birth.

Abstract
The aim of this study is to compare the efficacy and safety of valethamate bromide and placebo against placebo in shortening the duration of active labour. A prospective randomised trial of 158 low-risk women in spontaneous labour was conducted. After evaluation of the patients according to exclusion criteria 30 women were given valethamate bromide (Group 1) and 32 women were given placebo (Group 2). Labour duration was the main outcome measure. The duration of the active phase after starting the treatment was similar in the two groups at 225 and 219 min, respectively. However, differences were not significant between the 2 groups. Side effects such as tachycardia, flushing of the face and dryness of mouth were noted with valethamate bromide administration. In conclusion, valethamate bromide did not significantly shortened the duration of active labour in nulliparous women with a singleton pregnancy at term.

Abstract
In this study we aimed to explore the effects of epidural analgesia achieved by a combination of low-dose bupivacaine and fentanyl infused through an epidural catheter on mother, foetus and labour process in nulliparous at-term pregnant women during vaginal delivery. This study was designed in a prospective, randomised controlled manner. Epidural analgesia was achieved in 50 nulliparous women. Fifty nulliparous women did not undergo epidural analgesia procedure. The duration of the first stage of labour was significantly shortened, while the second stage was significantly lengthened in pregnant women who underwent epidural analgesia (p < 0.05). In conclusion, starting epidural analgesia application during the active phase of the first stage of labour may shorten the duration of the first stage compared with the group of nulliparous women not undergoing epidural analgesia. The factor that has an impact on this may be the addition of fentanyl to bupivacaine used for epidural analgesia.

Abstract
The neonatal line (NNL) is used to distinguish developmental events observed in enamel which occurred before and after birth. However, there are few studies reporting relationship between the characteristics of the NNL and factors affecting prenatal conditions. The aim of the study was to determine prenatal factors that may influence the NNL thickness in human deciduous teeth. The material consisted of longitudinal ground sections of 60 modern human deciduous incisors obtained from full-term healthy children with reported birth histories and prenatal factors. All teeth were sectioned in the labio-lingual plane using diamond blade (Buechler IsoMet 1000). Final specimens were observed using scanning electron microscopy at magnifications 320×. For each tooth, linear measurements of the NNL thickness were taken on its labial surface at the three levels from the cemento-enamel junction. The difference in the neonatal line thickness between tooth types and between males and females was statistically significant. A multiple regression analyses confirmed influence of two variables on the NNL thickness standardised on tooth type and the children's sex (z-score values). These variables are the taking of an antispasmodic medicine by the mother during pregnancy and the season of the child's birth. These two variables together explain nearly 17% of the variability of the NNL. Children of mothers taking a spasmolytic medicine during pregnancy were characterised by a thinner NNL compared with children whose mothers did not take such medication. Children born in summer and spring had a thinner NNL than children born in winter. These results indicate that the prenatal environment significantly contributes to the thickness of the NNL influencing the pace of reaching the post-delivery homeostasis by the newborn's organism.

Abstract
OBJECTIVE To reevaluate the role of the antispasmodic drug drotaverine in shortening the length of the active first stage of labor among nulliparous women. METHODS In a randomized, double-blind, placebo-controlled trial, 422 young nulliparous women admitted to Ain-shams University Maternity Hospital, Cairo, Egypt, in spontaneous labor were initially enrolled between May and December 2012. Drotaverine hydrochloride (40mg) or placebo was given at the start of the active phase of labor and then repeated every 2hours (maximum 3 doses). All participants were consistently managed in accordance with the local institutional intrapartum protocol. The primary outcome was the rate of cervical dilation. RESULTS After excluding women who delivered by cesarean, data were analyzed from 320 women. There was a significant difference in post-treatment labor pain scores, duration of the active phase of labor, and rate of cervical dilatation between the 2 groups (P<0.001 for all). There was no difference in maternal adverse effects. Kaplan-Meier survival analysis showed a greater probability of faster delivery among patients treated by drotaverine hydrochloride (log rank test; P<0.001). CONCLUSION Drotaverine hydrochloride was used effectively and safely to shorten the duration of the first stage of labor among nulliparous women with active spontaneous labor. ClinicalTrials.gov: NCT01639027.

Abstract
BACKGROUND Prolonged labour can lead to increased maternal and neonatal mortality and morbidity due to increased risks of maternal exhaustion, postpartum haemorrhage and sepsis, fetal distress and asphyxia and requires early detection and appropriate clinical response. The risks for complications of prolonged labour are much greater in poor resource settings. Active management of labour versus physiological, expectant management, has shown to decrease the occurrence of prolonged labour. Administering antispasmodics during labour could also lead to faster and more effective dilatation of the cervix. Interventions to shorten labour, such as antispasmodics, can be used as a preventative or a treatment strategy in order to decrease the incidence of prolonged labour. As the evidence to support this is still largely anecdotal around the world, there is a need to systematically review the available evidence to obtain a valid answer. OBJECTIVES To assess the effects of antispasmodics on labour in term pregnancies. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (28 February 2013), the ProQuest dissertation and thesis database, the dissertation database of the University of Stellenbosch and Google Scholar (28 February 2013) and reference lists of articles. We also contacted pharmaceutical companies and experts in the field. We did not apply language restrictions. SELECTION CRITERIA Randomised controlled trials comparing antispasmodics with placebo or no medication in women with term pregnancies. DATA COLLECTION AND ANALYSIS Two review authors independently screened abstracts and selected studies for inclusion, assessed risk of bias and extracted data. Data were checked for accuracy. We contacted trial authors when data were missing. MAIN RESULTS Twenty-one trials (n = 3286) were included in the review. Seventeen trials (n = 2617) were included in the meta-analysis. Antispasmodics used included valethamate bromide, hyoscine butyl-bromide, drotaverine hydrochloride, rociverine and camylofin dihydrochloride. Most studies included antispasmodics as part of their package of active management of labour. Overall, the quality of studies was poor, as only four trials were assessed as low risk of bias. Thirteen trials (n = 1995) reported on the duration of first stage of labour, which was significantly reduced by an average of 74.34 minutes when antispasmodics were administered (mean difference (MD) -74.34 minutes; 95% confidence Interval (CI) -98.76 to -49.93). Seven studies (n = 797) reported on the total duration of labour, which was significantly reduced by an average of 85.51 minutes (MD -85.51 minutes; 95% CI -121.81 to -49.20). Six studies (n = 820) had data for the outcome: rate of cervical dilatation. Administration of antispasmodics significantly increased the rate of cervical dilatation by an average of 0.61 cm/hour (MD 0.61 cm/hour; 95% CI 0.34 to 0.88). Antispasmodics did not affect the duration of second and third stage of labour. The rate of normal vertex deliveries was not affected either. Only one study explored pain relief following administration of antispasmodics and no conclusions can be drawn on this outcome. There was significant heterogeneity for most outcomes and therefore, we undertook random-effects meta-analysis. Subgroup analysis was undertaken to explore heterogeneity, but remained largely unexplained. Maternal and neonatal adverse events were reported inconsistently. The main maternal adverse event reported was tachycardia. No serious neonatal adverse events were reported. AUTHORS' CONCLUSIONS There is low quality evidence that antispasmodics reduce the duration of first stage of labour and increase the cervical dilatation rate. There is very low quality evidence that antispasmodics reduce the total duration of labour. There is moderate quality evidence that antispasmodics do not affect the rate of normal vertex deliveries. There is insufficient evidence to make any conclusions regarding the safety of these drugs for both mother and baby. Large, rigorous randomised controlled trials are needed to evaluate the effect of antispasmodics on prolonged labour and to evaluate their effect on labour in a context of expectant management of labour.

Abstract
OBJECTIVE Development of human tooth enamel is a part of a foetus's development; its correctness is the outcome of genetic and maternal factors shaping its prenatal environment. Many authors reported that individuals born in different seasons experience different early developmental conditions during pregnancy. In this study, we investigated the effects of season of birth and selected maternal factors on enamel thickness of deciduous incisors. DESIGN Dental sample comprises 60 deciduous incisors. The parents who handed over their children's teeth for research fill in questionnaires containing questions about the course of pregnancy. All teeth were sectioned in the labio-linqual plane using diamond blade (Buechler IsoMet 1000). The final specimens were observed by way of scanning electron microscopy at magnifications 80× and 320×. The thickness of total enamel (TE), prenatally (PE) and postnatally (PSE) formed enamel was measured. RESULTS Children born in summer and in spring (whose first and second foetal life fall on autumn and winter) have the thinnest enamel. Season of birth, number of children in family, diseases and spasmolytic medicines using by mother during pregnancy explained almost 13% of the variability of TE. Regression analysis proved a significant influence of the season of birth and selected maternal factors on the PE thickness - these factors explained over 17% of its variability. Neither of analysed variables had influenced PSE. CONCLUSIONS Our findings suggests that the thickness of enamel of deciduous incisors depends on the season of birth and some maternal factors. The differences were observed only in the prenatally formed enamel.

Abstract
BACKGROUND Prolonged labour can lead to increased maternal and neonatal mortality and morbidity due to increased risks of maternal exhaustion, postpartum haemorrhage and sepsis, fetal distress and asphyxia and requires early detection and appropriate clinical response. The risks for complications of prolonged labour are much greater in poor resource settings. Active management of labour versus physiological, expectant management, has shown to decrease the occurrence of prolonged labour. Administering antispasmodics during labour could also lead to faster and more effective dilatation of the cervix. Interventions to shorten labour, such as antispasmodics, can be used as a preventative or a treatment strategy in order to decrease the incidence of prolonged labour. As the evidence to support this is still largely anecdotal around the world, there is a need to systematically review the available evidence to obtain a valid answer. OBJECTIVES To assess the effects of antispasmodics on labour in term pregnancies. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (2 September 2011), the ProQuest dissertation and thesis database, the dissertation database of the University of Stellenbosch (2 September 2011), Google Scholar (2 September 2011) and reference lists of articles. We also contacted pharmaceutical companies and experts in the field. We did not apply language restrictions. SELECTION CRITERIA Randomised controlled trials comparing antispasmodics with placebo or no medication in women with term pregnancies. DATA COLLECTION AND ANALYSIS Two review authors independently screened abstracts and selected studies for inclusion, assessed risk of bias and extracted data. Data were checked for accuracy. We contacted trial authors when data were missing. MAIN RESULTS Nineteen trials (n = 2798) were included in the review. Fifteen trials (n = 2129) were included in the meta-analysis. Antispasmodics used included valethamate bromide, hyoscine butyl-bromide, drotaverine hydrochloride, rociverine and camylofin dihydrochloride. Most studies included antispasmodics as part of their package of active management of labour. Overall, the quality of studies was poor, as only four trials were assessed as low risk of bias. Eleven trials (n = 1507) reported on the duration of first stage of labour, which was significantly reduced by an average of 65.80 minutes when antispasmodics were administered (mean difference (MD) -65.80 minutes; 95% confidence Interval (CI) -92.32 to -39.28). Seven studies (n = 797) reported on the total duration of labour, which was significantly reduced by an average of 85.51 minutes (MD -85.51 minutes; 95% CI -121.81 to -49.20). Five studies (n = 632) had data for the outcome: rate of cervical dilatation. Administration of antispasmodics significantly increased the rate of cervical dilatation by an average of 0.55 cm/h (MD 0.55 cm/h; 95% CI 0.22 to 0.87). Antispasmodics did not affect the duration of second and third stage of labour. The rate of normal vertex deliveries was not affected either. Only one study explored pain relief following administration of antispasmodics and no conclusions can be drawn on this outcome. There was significant heterogeneity for most outcomes and therefore, we undertook random-effects meta-analysis. Subgroup analysis was undertaken to explore heterogeneity, but remained largely unexplained. Maternal and neonatal adverse events were reported inconsistently. The main maternal adverse event reported was tachycardia. No serious neonatal adverse events were reported. AUTHORS' CONCLUSIONS There is low quality evidence that antispasmodics reduce the duration of first stage of labour and increase the cervical dilatation rate. There is very low quality evidence that antispasmodics reduce the total duration of labour. There is moderate quality evidence that antispasmodics do not affect the rate of normal vertex deliveries. There is insufficient evidence to make any conclusions regarding the safety of these drugs for both mother and baby. Large, rigorous randomised controlled trials are needed to evaluate the effect of antispasmodics on prolonged labour and to evaluate their effect on labour in a context of expectant management of labour.

Abstract
BACKGROUND Labour is a normal physiological process, but is usually associated with pain and discomfort. Numerous methods are used to relieve labour pain. These include pharmacological (e.g. epidural, opioids, inhaled analgesia) and non-pharmacological (e.g. hypnosis, acupuncture) methods of pain management. Non-opioid drugs are a pharmacological method used to control mild to moderate pain. OBJECTIVES To summarise the evidence regarding the effects and safety of the use of non-opioid drugs to relieve pain in labour. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (15 February 2012). SELECTION CRITERIA Randomised controlled trials (RCTs) using non-opioid drugs (non-steroidal anti-inflammatory drugs (NSAIDs); paracetamol; antispasmodics; sedatives and antihistamines) in comparison with placebo or standard care; different forms of non-opioid drugs (e.g. sedatives versus antihistamines); or different interventions (e.g. non-opioids versus opioids) for women in labour. Quasi-RCTs and trials using a cross-over design were not included. Cluster-randomised RCTs were eligible for inclusion but none were identified for inclusion. DATA COLLECTION AND ANALYSIS Two review authors independently assessed for inclusion all studies identified by the search strategy, carried out data extraction and assessed risk of bias. We resolved any disagreement through discussion with a third author. Data were checked for accuracy. MAIN RESULTS Nineteen studies randomising a total of 2863 women were included in this review. There were three main comparison groups: 15 studies compared non-opioid drugs with placebo or no treatment (2133 women); three studies compared non-opioid drugs with opioids (563 women); and three studies compared one type of non-opioid drug with a different type or dose of non-opioid drug (590 women). Some of the studies included three or more groups and so have been put in more than one comparison. Overall, there was little difference between groups for most of the comparisons. Any differences observed for outcomes were mainly limited to one or two studies. Non-opioid drugs (sedatives) were found to offer better pain relief (mean difference (MD) -22.00; 95% confidence interval (CI) -35.86 to -8.14, one trial, 50 women), better satisfaction with pain relief (sedatives and antihistamines) (risk ratio (RR) 1.59; 95% CI 1.15 to 2.21, two trials, 204 women; RR 1.80; 95% CI 1.16 to 2.79, one trial, 223 women) and better satisfaction with the childbirth experience (RR 2.16; 95% CI 1.34 to 3.47, one trial, 40 women) when compared with placebo or no treatment. However, women having non-opioid drugs (NSAIDs or antihistamines) were less likely to be satisfied with pain relief compared with women having opioids (RR 0.50; 95% CI 0.27 to 0.94, one trial, 76 women; RR 0.73; 95% CI 0.54 to 0.98, one trial, 223 women). Women receiving the antihistamine hydroxyzine were more likely to express satisfaction with pain relief compared with the antihistamine promethazine (RR 1.21; 95% CI 1.02 to 1.43, one trial, 289 women). Women receiving sedatives were more likely to express satisfaction with pain relief compared with antihistamines (RR 1.52; 95% CI 1.06 to 2.17, one study, 157 women). The majority of studies were conducted over 30 years ago. The studies were at unclear risk of bias for most of the quality domains.Opioids appear to be superior to non-opioids in satisfaction with pain relief, while non-opioids appear to be superior to placebo for pain relief and satisfaction with the childbirth experience. There were little data and no evidence of a significant difference for any of the comparisons of non-opioids for safety outcomes. AUTHORS' CONCLUSIONS Overall, the findings of this review demonstrated insufficient evidence to support a role for non-opioid drugs on their own to manage pain during labour.

Abstract
AIM The aim of this study was to evaluate the effectiveness of meperidine, administered during the first stage of labor in patients with uterine dystocia, on the duration of labor and neonatal acid-base status at birth. MATERIAL AND METHODS We randomly assigned 240 nulliparous women with a singleton pregnancy at term who were diagnosed with uterine dystocia in labor at 4-6-cm cervical dilatation to receive either a single dose of 50 mg meperidine in 10 mL of saline (slow intravenous injection over 2 min) or 10 mL of isotonic saline (control group). The primary outcome measures were duration of labor (from the time of beginning of the intervention to the time of the expulsion of the fetal head) and umbilical cord arterial acid-base status. RESULTS The evidence revealed no statistically significant difference between the two groups in length of labor (188.2 ± 92.3 min in the meperidine group compared to 205.4 ± 96.1 min in the placebo group, P = 0.159). The pH of the umbilical cord arterial samples was lower in the meperidine group than in the control group, although the difference was not statistically significant (P = 0.089). CONCLUSION Because of the absence of any beneficial effect of meperidine on uterine dystocia, its use in labor should be limited to pain relief in the absence of epidural analgesia.

Abstract
INTRODUCTION Laboring women are often admitted to labor units under criteria that are commonly associated with the onset of active-phase labor (i.e., cervical dilatation of 3-5 cm in the presence of regular contractions). Beginning with these criteria through complete dilatation, this systematic review describes labor duration and cervical dilation rates among low-risk, nulliparous women with spontaneous labor onset. METHODS Studies published in English (between 1990 and 2008) were identified via MEDLINE and CINAHL searches. Data were abstracted and weighted "active labor" durations (i.e., from 3-5 cm through complete dilatation) and linear dilation rates were calculated. RESULTS Eighteen studies (n = 7009) reported mean "active labor" duration. The weighted mean duration was 6.0 hours, and the calculated dilation rate was 1.2 cm per hour. These findings closely parallel those found at the median. At the statistical limits, the weighted "active labor" duration was 13.4 hours (mean + 2 standard deviations) and the dilation rate was 0.6 cm per hour (mean - 2 standard deviations). DISCUSSION These findings indicate that nulliparous women with spontaneous labor onset have longer "active" labors and therefore slower dilation rates than are traditionally associated with active labor when commonly used criteria are applied as the starting point. Revision of existing active labor expectations and/or criteria used to prospectively identify active phase onset is warranted.

Abstract
OBJECTIVES Cervical dilatation is a poorly understood process. Various drugs have been used to facilitate this process and reduce the duration of labour and thereby reduce feto-maternal complications. The present study is an attempt to compare and evaluate the efficacy of Drotaverine hydrochloride and Valethamate bromide in the process of cervical dilatation and labour augmentation. STUDY DESIGN A prospective randomised trial of 146 low-risk women in spontaneous labour was conducted. 49 women were given Drotaverine (Group 1), 49 women were given Valethamate (Group 2) and 48 women were given placebo (Group 3). At 4 cm of cervical dilatation, elective amniotomy was done and the injection was given intramuscularly, and repeated every hour for a maximum of three doses. RESULTS There was a statistically significant difference in the mean injection-delivery times (time from first injection to delivery of the baby), which was 183.2 min (SD 78.8) in the Drotaverine group compared to 206.5 min (SD 69.7) in the Valethamate group, and 245 min (SD 70.9) in the control group. The mean cervical dilatation rate (cm/h) was 3 (SD 1.4), 2.4 (SD 0.9) and 1.9 (SD 0.6) in groups 1, 2 and 3, respectively, and these differences were statistically significant. There were no statistically significant differences in the duration of second and third stage of labour. Transient side effects such as foeto-maternal tachycardia, flushing of the face and dryness of mouth were noted with Valethamate. A few patients complained of headache in the Drotaverine group. CONCLUSIONS Both Drotaverine and Valethamate appear to significantly help cervical dilatation and augment first stage of labour. But, Drotaverine is superior to Valethamate with fewer side effects.

Abstract
In a rural community of Rajasthan in north India, we explored family, community and provider practices during labor and childbirth, which are likely to influence newborn health outcomes. A range of qualitative data-gathering methods was applied in two rural clusters of Udaipur district. This paper reports on the key findings from eight direct observations of labor and childbirth at home and in primary health facilities, as well as 10 focus group discussions, 18 case interviews with recently delivered women and 39 key informant interviews carried out within the community. Although most families preferred home delivery, health-facility deliveries were preferred for first births, especially among adolescents. A team of birth attendants led by a traditional birth attendant or an elder female relative took decisions and performed key functions during home childbirth. Modern providers were commonly invited to administer intramuscular oxytocin injections to hasten home delivery, whereas health staff tended to do the same during facility deliveries. The practice of applying forceful fundal pressure, stemming from overriding concern about the woman's inability to deliver spontaneously, was near universal in both situations. In both facilities and homes, monitoring of labor was largely restricted to repeated unhygienic vaginal examinations with little or no monitoring of fetal or maternal well-being. Babies born at home remained lying on the wet floor till the placenta was delivered. The cord was usually tied using available twine or ceremonial thread and cut using a new blade. In facility settings, drying and wrapping of the baby after birth was delayed and preparedness for resuscitation was minimal. Families believed in delaying breast-feeding till 3 days after birth, when they believed breast milk became available. Even hospital staff discharged the mother and newborn without efforts to initiate breast-feeding. A combination of traditional and modern practices, rooted in the concept of inducing heat to facilitate labor, occurred in both home and facility delivery settings. Programs to improve neonatal survival in such rural settings will need to invest both in strengthening primary health services provided during labor and delivery through training and monitoring, and in community promotion of improved newborn care practices.

Abstract
Remarkably, there has been very little detailed research on clinical practice in Russia and its neighbours in what was the USSR, even though it is known that the USSR was isolated from many international developments, in particular evidence-based medicine. In this study we examine obstetric practice, an area of practice where there is an extensive body of evidence on the appropriateness of many interventions. The study is undertaken in Tula, a region 200 km south of Moscow. Building on earlier detailed analyses of data from the facilities in the region, it reports a series of structured interviews with 52 obstetricians from all 19 facilities in the region, designed to identify patterns of prescribing, supplemented by 36 more detailed re-interviews to explore reasons for the differing practices. The study demonstrates a widespread divergence from internationally accepted practice. Maternity care is extremely medicalised but many non-evidence based medicines are used. Some are heavily marketed by large pharmaceutical companies, some were widely used during the Soviet period but never evaluated, and a few are not known to be used anywhere else in the world. For several conditions, the most widely used drugs are clearly inferior to alternative products and some are used for indications quite different from those in other countries. This study contributes to the growing evidence that much of the care provided in Russian maternity units is ineffective or potentially dangerous but also begins to offer some explanations for why this is, including a lack of access to information and a lack of awareness of the concept of evidence-based practice.

Abstract
OBJECTIVES To study and compare the efficacy and side effects of drotaverine hydrochloride and hyoscine-N-butylbromide in the augmentation of labor. METHODS A prospective randomized trial of 150 women in active labor included 50 women given drotaverine (group 1), 50 women given hyoscine-N-butylbromide (group 2), and 50 women given no medication (group 3). Duration of labor, rate of cervical dilation, mode of delivery, side effects, and neonatal outcome were compared among the groups. RESULTS The mean duration of the active phase of labor was 4.48+/-2.26 h, 3.9+/-2.42 h, and 3.6+/-2.07 h in groups 1, 2, and 3, respectively. The mean rate of cervical dilation was 2.6 cm/h, 2.4 cm/h, and 2.5 cm/h, respectively. The differences were not statistically significant. There was no difference in the duration of the second and third stages of labor. No adverse maternal or fetal outcomes were noted. CONCLUSION Drotaverine hydrochloride and hyoscine-N-butylbromide do not have a role in augmentation of labor.
