Abstract
OBJECTIVE To assess the safety and efficacy of hyoscine butyl bromide (HBB) in primipara with prolonged 1st stage of labor. MATERIALS AND METHODS A double-blinded randomized controlled trial included 100 primiparas diagnosed with prolonged labor. They were randomly divided two equal groups. Group I received 40 mg HBB intravenously. Group II received 2 ml of normal saline. The primary outcome was the duration of the 1st stage of labor. Secondary outcomes included success of vaginal delivery, rate of cervical dilation, duration of 2nd and 3rd stages of labor, causes of CS, neonatal outcome and drug side effects. RESULTS The duration of the 1st stage was 322.3 ± 89.8 min in women who received HBB compared with 451.3 ± 198.3 min in the control women (P < 0.001). The rate of cervical dilation was increased from 0.4 ± 0.2 to 1.5 ± 0.6 in women who received HBB compared with its increase from 0.4 ± 0.1 to 0.9 ± 0.2 in other women (P < 0.001). The rate of CS were significantly higher in control women when compared to those received HBB (34 vs. 20%, P < 0.001). The commonest indication for the operation was arrest of cervical dilatation (28 and 16%, respectively). CONCLUSION HBB is associated with shortening of the 1st stage, lowered rate of CS without any side effects. CLINICAL TRIAL GOV ID NCT03430362 date of registration 6 February 2018. Synopsis Hyoscine butyl bromide is associated with shortening of the 1st stage, lowered rate of CS in primiparas with prolonged labor.

[PMID: 33417640 DOI: 10.1007/s13224-020-01343-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Accepted: 06/21/2020] [Indexed: 11/27/2022] Open
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.

[PMID: 32404072 PMCID: PMC7218842 DOI: 10.1186/s12884-020-2832-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Accepted: 02/21/2020] [Indexed: 11/10/2022] Open
Abstract
Background The objective of this systematic review and meta-analysis was to assess the effectiveness of hyoscine n-butylbromide in labor progress. Methods The databases including PubMed, the Cochrane Library, Science-Direct, Scopus and Web of Science were searched for studies published up to December 2019. Articles that published as randomized controlled trials (RCTs), and full-text articles published in English or other languages were included and participants were primi or multigravida women who were in active phase of labor. The intervention included HBB compared to placebo (normal saline) that was used during active phase of labor. Pooled estimates were measured using the fixed or random effect model, while the overall effect was reported in a mean difference (MD). All data were analyzed using Review Manager 5.3. Results Twenty studies involving 3108 women were included in meta-analysis. Based on subgroup analysis by parity, use of HBB significantly reduced the duration of the first stage of labor in primigravida women (MD = − 57.73; 95% CI: [− 61.48, − 53.60]) and in multigravida women (MD = − 90.74; 95% CI: [− 97.24, − 84.24]). Administering HBB could reduce the second stages of labor in primigravidas and multigravidas about 6 min and 4 min respectively. Also, HBB reduced the duration of the third stage of labor in multigravidas about 3 min. APGAR score at one and 5 min after birth was not affected. The main maternal adverse effect was tachycardia and dry mouth. Labor duration in studies in which the participants were primi-and multigravida was not presented based on separate parities except for four papers, and the route of HBB administration was not the same across all studies. Conclusions Although, the effect of HBB was minimal when multigravidas and primigravidas women were considered together, the HBB was clinically effective in primigravida and multigravida women for shortening the first and the second stages of labor. Also, HBB could reduce the length of the third stage of labor in multigravidas.

Abstract
BACKGROUND Due to the debilitating effects of severe labour pains, labour pain management continues to be an important subject that requires much attention. Thus, this study sought to gain a detailed insight into the experiences of midwives on pharmacological and non-pharmacological labour pain management strategies in a resource limited clinical context. METHODS A descriptive exploratory qualitative design was adopted for this study which allowed in-depth follow-up of the midwives' comments resulting in a full understanding of emerging findings. Face-to-face individual interviews were conducted, transcribed and data were analysed using content analysis procedures. Verbatim quotes were used to support the findings. RESULTS Midwives employed different pain control measures including pharmacological and non-pharmacological methods such as psychological care, sacral massage and deep breathing exercises. Doctors prescribed analgesics most of the time while in some cases, the midwives independently administered the drugs. They assisted women who had epidural anaesthesia given by anaesthetists. The midwives did not administer adequate analgesics because of fear of side effects of analgesics. Although the midwives exhibited knowledge on drugs used for labour pain management, they did not regularly administer analgesics and non-pharmacological care provided were inadequate due to increased workload. Some of the midwives showed empathy towards women and supported the women. Most of the midwives perceived labour pain as normal and encouraged women to bear pain. CONCLUSION Midwives require regular education on labour pain management and they should pay attention to women in labour individually and administer the care that meets their need.

Abstract
BACKGROUND Unripe cervix prevents entering the endometrial cavity during intrauterine procedures. Mechanical dilatation of cervical canal might cause undesirable complications. OBJECTIVE To investigate the substitute of mechanical intervention with chemical treatment by administering hyoscine to patients. MATERIALS AND METHODS Sixty non-pregnant women, 20-70 years of age, with a closed cervix who were scheduled for an intrauterine procedure, were randomly divided into two groups. Group A as experimental (received two doses of hyoscine) and group B, as control group (received two doses of vitamin B6) in the vagina (8 hrs and 2 hrs before procedure) and the effect of these two drugs on dilatation and consistency of cervix were studied. RESULTS Statistics resulted from Mann-Whitney U test (p=0.027) and 2(p=0.002) indicated that in premenopausal women, the priming effect of hyoscine on dilatation and consistency of uterine cervix was significant, but there were no significant benefits from giving vaginal hyoscine to menopausal women preoperatively (p=0.603). CONCLUSION Hyoscine proved a good choice for inducing cervical priming before intrauterine procedures in premenopausal women.

Abstract
BACKGROUND The diagnosis of labor onset has been described as one of the most important judgments in maternity care. There is compelling evidence that the duration of both latent and active phase labor are clinically important and require consistent approaches to measurement. In order to measure the duration of labor phases systematically, we need standard definitions of their onset. We reviewed the literature to examine definitions of labor onset and the evidentiary basis provided for these definitions. METHODS Five electronic databases were searched using predefined search terms. We included English, French and German language studies published between January 1978 and March 2014 defining the onset of latent labor and/or active labor in a population of healthy women with term births. Studies focusing exclusively on induced labor were excluded. RESULTS We included 62 studies. Four 'types' of labor onset were defined: latent phase, active phase, first stage and unspecified. Labor onset was most commonly defined through the presence of regular painful contractions (71% of studies) and/or some measure of cervical dilatation (68% of studies). However, there was considerable discrepancy about what constituted onset of labor even within 'type' of labor onset. The majority of studies did not provide evidentiary support for their choice of definition of labor onset. CONCLUSIONS There is little consensus regarding definitions of labor onset in the research literature. In order to avoid misdiagnosis of the onset of labor and identify departures from normal labor trajectories, a consistent and measurable definition of labor onset for each phase and stage is essential. In choosing standard definitions, the consequences of their use on rates of maternal and fetal morbidity must also be examined.

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.
