Effectiveness of Dry Heat Versus Moist Heat Modalities on Pain Intensity and Wound Healing of Episiotomies Among Postnatal Women: A Systematic Review and Meta-Analysis.

OBJECTIVES: Comparison of the effects of dry heat versus moist heat therapy modalities on the intensity of pain and wound healing of episiotomies among postnatal women. DESIGN: A Systematic review and meta-analysis of controlled trials. DATA SOURCES: Six databases searched for original articles using relevant keywords until September 10, 2023, without time or language restrictions. REVIEW/ANALYSIS METHODS: All analyses employed Comprehensive Meta-Analysis (CMA) V.2. The measure of heterogeneity was computed using Cochran's Q-value. The I2 index was employed to quantitatively demonstrate heterogeneity. Statistical significance was reported for P-values <0.05 and I2>50%. RESULTS: Four quasi-experimental and three randomized controlled trials (RCTs) studies with moderate-to-good quality evidence met inclusion criteria. On the third to fifth day after the intervention in the dry heat group, the amount of pain was significantly lower than in the group that used moist heat [MD (95% CI) =-1.395 (-2.374, -0.416), P=0.005]. The use of a hair dryer significantly reduced pain (P=0.029), but an infrared lamp did not significantly reduce pain compared to moist heat (P=0.064). As compared to the moist heat group, the women using dry heat experienced better wound healing to the extent of 2.002 units of the REEDA (Redness, Edema, Ecchymosis, Discharge, Approximation) scale, which was statistically significant [MD (95% CI) = -2.002 (-2.785, -1.219), P<0.001]. CONCLUSION: Compared to sitz baths, dry heat reduced pain and improved episiotomy site healing in postnatal women. Therefore, dry heat, especially hair dryers, is suggested as a non-pharmacological strategy inside maternity hospitals, but additional targeted, high-quality trials are needed.

Efficient administration of a combination of nifedipine and sildenafil citrate versus only nifedipine on clinical outcomes in women with threatened preterm labor: a systematic review and meta-analysis.

BACKGROUND: Preterm labor (PTL) is a common and serious pregnancy disorder that can cause long-term neurological issues in the infant. There are conflicting studies concerning whether sildenafil citrate (SC) reduces preterm labor complications. Therefore, the meta-analysis aimed to examine the clinical outcomes in women with threatened PTL who received nifedipine plus SC therapy versus only nifedipine. METHODS: For the original articles, six databases were searched using relevant keywords without restriction on time or language until January 13, 2024. The Cochrane risk-of-bias tool for randomized trials (RoB) and the Risk of Bias Assessment Tool for Nonrandomized Studies (RoBANS) were both used to assess the risk of bias in randomized and non-randomized studies, and GRADE determined the quality of our evidence. Meta-analysis of all data was carried out using Review Manager (RevMan) version 5.1. RESULTS: Seven studies with mixed quality were included in the meta-analysis. The study found that combining nifedipine and SC resulted in more prolongation of pregnancy (MD = 6.99, 95% CI: 5.32, 8.65, p < 0.00001), a lower rate of delivery in the 1st to 3rd days after hospitalization (RR = 0.62, 95% CI: 0.50, 0.76, p < 0.00001), a higher birth weight (252.48 g vs. nifedipine alone, p = 0.02), and the risk ratio of admission to the neonatal intensive care unit (NICU) was significantly lower (RR = 0.62, 95% CI: 0.50, 0.76, p < 0.00001) compared to nifidepine alone. The evidence was high for prolongation of pregnancy, delivery rate 24-72 h after admission, and NICU admission, but low for newborn birth weight. CONCLUSIONS: Given the effectiveness of SC plus nifedipine in increased prolongation of pregnancy and birth weight, lower delivery in the 1st to 3rd days after hospitalization, and NICU admission, Gynecologists and obstetricians are suggested to consider this strategy for PTL management, although additional article rigor is required to improve the quality of the evidence.

The Effect of Hyoscine N-Butyl Bromide Rectal on the Duration of Labour and Rate of Cervical Dilatation: A Systematic Review and Meta-Analysis.

OBJECTIVE: The current meta-analysis was designed to investigate the impact of Hyoscine N-butyl bromide (HBB) rectal on labour duration and the rate of cervical dilatation by consolidating the available data. METHODS: The search of Medline through the PubMed interface, Scopus, ScienceDirect, and the Cochrane Central Register of Controlled Trials (CENTRAL) was performed for original articles concerning the effects of HBB rectal on the duration of labour published prior to 26 June 2023. Search terms were based on Medical Subject Headings without time and language restrictions. They included: Hyoscine, Scopolamine, HBB, Buscopan, Buscolysin, Buscapine, rectal, suppository, childbirth, delivery, active phase, second stage, cervical dilatation, labour, labour, and duration of labour. The Comprehensive Meta-Analysis V3 software was used for all analyses. RESULTS: Five randomized control trials and 1 non-randomized study involving 1310 women were included in the systematic review. Two studies were excluded from the meta-analysis because of heterogeneous interventions and a lack of mean and SD results. The results determined that HBB rectal administration significantly decreased the duration of the active phase (pooled mean difference -193.893; 95% CI -229.173 to -158.613, P < 0.001; I2 squares = 90.097%) and second stage of labour (pooled mean difference -2.911; 95% CI -5.486 to -0.336, P = 0.027; I2 squares = 90.097%). Also, the cervical dilatation rate in the active phase of labour was 0.981 cm/h higher than in the control group (I2 = 0.0%; P < 0.001). CONCLUSION: This meta-analysis found that HBB rectal administration shortened the active labour phase and second stage and increased the rate of cervix dilatation; consequently, it can be used as a cost-effective intervention for low-risk pregnant women during labour. However, our findings also suggest that more robust clinical trials are required to generate evidence and confirm the use of HBB during labour for clinical practice guidelines.

A systematic review and meta-analysis on the effects of statins on pregnancy outcomes.

BACKGROUND AND AIMS: Statins are contraindicated in pregnancy, due to their potential teratogenicity. However, data are still inconsistent and some even suggest a potential benefit of statin use against pregnancy complications. We aimed to investigate the effects of statins on pregnancy outcomes, including stillbirth, fetal abortion, and preterm delivery, through a systematic review of the literature and a meta-analysis of the available clinical studies. METHODS: A literature search was performed through PubMed, Scopus, and Web of Science up to 16 May 2020. Data were extracted from 18 clinical studies (7 cohort studies, 2 clinical trials, 3 case reports, and 6 case series). Random effect meta-analyses were conducted using the restricted maximum likelihood method. The common effect sizes were calculated as odds ratios (ORs) and their 95% confidence interval (CI) for each main outcome. RESULTS: Finally, nine studies were included in the meta-analysis. There was no significant association between statin therapy and stillbirth [OR (95% CI) = 1.30 (0.56, 3.02), p=0.54; I2 = 0%]. While statin exposure was significantly associated with increased rates of spontaneous abortion [OR (95% CI) = 1.36 (1.10-1.68), p=0.004, I2 = 0%], it was non-significantly associated with increased rates of induced abortion [OR (95% CI) = 2.08 (0.81, 5.36), p=0.129, I2 = 17.33%] and elective abortion [OR (95% CI) = 1.37 (0.68, 2.76), p=0.378, I2 = 62.46%]. A non-significant numerically reduced rate of preterm delivery was observed in statin users [OR (95% CI) = 0.47 (0.06, 3.70), p=0.47, I2 = 76.35%]. CONCLUSIONS: Statin therapy seems to be safe as it was not associated with stillbirth or induced and elective abortion rates. Significant increase after statin therapy was, however, observed for spontaneous abortion. These results need to be confirmed and validated in future studies.

The Experiences of Recovered COVID-19 Patients in Baqiyatallah Hospital: A Qualitative Study.

The emerging COVID-19 disease affects not only the physical health but also the emotional and psychological health of patients. This study aimed to explain the experiences of 22 recovered COVID-19 patients in Baqiyatallah hospital, Tehran, Iran. Data were collected through in-depth semi-structured interviews. All interviews were recorded and transcribed and then analyzed using the conventional content analysis method. This resulted in emergence of 3 themes "emotional-sensational paradox", "spiritual growth", and "experienced mental-psychological effects", with 11 main categories and 33 subcategories. The results of the study can be used to develop instructions and guidelines for the families of patients as well as healthcare teams to provide effective measures and interventions to minimize the suffering of patients and the damage to mental health.

Fetal toxicity associated with statins: A systematic review and meta-analysis.

BACKGROUND AND AIMS: Statins are the drugs of choice for decreasing elevated low-density lipoprotein cholesterol. Based mostly on animal studies and case reports, they are forbidden to pregnant women and in the preconception period because of their possible teratogenic effects, for which causality has never been proven. The aim of this study was to systematically review the existing studies and to perform a meta-analysis on this topic. METHODS: The databases PubMed/MEDLINE, Scopus, and Web of Science were searched since the inception until May 16, 2020. The risk of bias for each clinical trial was evaluated using the Cochrane handbook criteria for systematic reviews. The National Institutes of Health (NIH) quality assessment tool was used for the evaluation of cohort and cross-sectional studies. Meta-analysis was performed on the extracted data. Heterogeneity was assessed using I2 measure and Cochrane's Q statistic. We calculated a pooled estimate of odds ratio (OR) and 95% confidence intervals (CI) using a random-effects model. RESULTS: 23 studies (nine cohort studies, six case reports, six case series, one population-based case-referent study and one clinical trial) with 1,276,973 participants were included in the systematic review and 6 of them (n = 1,267,240 participants) were included in meta-analysis. The results of the critical review did not suggest a clear-cut answer to the question whether statin treatment during pregnancy is associated with an increased rate of birth defects or not, while the results of the meta-analysis indicated that statin use does not increase birth defects [OR (95%CI): 1.48 (0.90, 2.42), p = 0.509], including cardiac anomalies [2.53 (0.81, 7.93), p = 0.112] and other congenital anomalies [1.19 (0.70, 2.03), p = 0.509)]. CONCLUSIONS: We observed no significant increase of birth defects after statin therapy. Thus, there is still no undoubtful evidence that statin treatment during pregnancy is teratogenic, and this issue still needs to be investigated, especially there are more and more pregnant women at high CVD risk that could have benefited from the statin therapy.

Effect of COVID-19 on Mortality of Pregnant and Postpartum Women: A Systematic Review and Meta-Analysis.

BACKGROUND: Based on what is known at this time, pregnant women are at an increased risk of severe illness from COVID-19 compared to nonpregnant women. Additionally, pregnant women with COVID-19 might have an increased risk of adverse pregnancy outcomes. To investigate the effects of coronavirus disease 2019 (COVID-19) on mortality of pregnant and postpartum women, we performed a systematic review of available published literature on pregnancies affected by COVID-19. METHODS: Web of Science, SCOPUS, and MEDLINE- databases were searched for original studies concerning the effect of COVID-19 on mortality of pregnant and postpartum women published by July 10, 2020. Meta-analyses of proportions were used to combine data and report pooled proportions. RESULTS: 117 studies with a total of 11758 pregnant women were included. The age ranged between 15 and 48 years. Most subjects were infected with SARS-CoV-2 in the third trimester. Disease severity was not reported in 1125 subjects. Maternal mortality was 1.3%. In 100% of fatal cases with adequate data, fever alone or with cough was one of the presenting symptoms. Also, dyspnea (58.3%) and myalgia (50%) were the most common symptoms. Sore throat (8.3%) and gastrointestinal symptoms (anorexia, nausea) (8.3%) were rare. The rate of comorbidities was 20% among COVID-19 deaths. The majority of COVID-19-infected women who died had cesarean section (58.3%), 25% had a vaginal delivery, and 16.7% of patients were not full term. CONCLUSION: COVID-19 infection in pregnant women was associated with higher rates (and pooled proportions) of cesarean section and mortality. Because new data are continuously being generated and published, the findings of this study can be complete and updated with new researches. The results of this study can guide and improve prenatal counseling of COVID-19-infected pregnant women.

A Review Study on the Neonatal Outcomes of Pregnant Women with COVID-19.

COVID-19 is a fatal respiratory disease caused by a novel coronavirus that quickly became a pandemic. Pregnant women and neonates are two vulnerable groups in COVID-19 infections because the immune system weakens during pregnancy. The present review study was conducted to investigate the rate of vertical transmission in infants born to women with COVID-19 infections and to describe the characteristics of the affected infants. We conducted a search of the various scientific databases using relevant keywords. All English-language studies involving neonates born to women who had COVID-19 infections were included. The main outcomes were rates of vertical transmission and the characteristics of the affected newborns. Out of 13 selected studies, 103 newborns were involved. The rate of vertical transmission was 5.4%. Of the five infected newborns, four were full-term and one was preterm. All were born by Cesarean section. The clinical symptoms were vomiting, fever, lethargy, shortness of breath, and cyanosis. In four newborns, a chest x-ray showed evidence of pneumonia. The most common laboratory finding was leukocytosis and elevated creatine kinase levels. One newborn needed mechanical ventilation. All newborns recovered and were discharged. The findings of this review study showed that the prognosis of newborns of infected mothers was satisfactory, and clinical symptoms of infected neonates did not differ from adults and were nonspecific. Due to the low amount of data regarding this field, further studies with higher sample sizes are required for more definitive conclusions.

Does SARS-CoV-2 Threaten Male Fertility?

In the continuing COVID-19 pandemic, one of the most important concerns in reproductive health is the issue of male fertility of recovered patients. In this study, we discuss the potential mechanisms that justify the possible impact of COVID-19 on male fertility. The main point of entry of SARS-CoV-2 into the host cells appears to be through the viral spike protein which permits entry into cells via the angiotensin-converting enzyme 2 (ACE2 receptor). In human testes, ACE2 is enriched in Sertoli and Leydig cells and spermatogonia. Also, it seems that there is a mild or severe cytokine storm in patients with severe COVID-19, and such changes may affect fertility. It should also be mentioned that the orchitis caused by the SARS-CoV-2 virus may have an important impact on fertility. Prolonged and high fever may lead to changes in testicular temperature and destroy germ cells. In general, there is little evidence for a definite conclusion, but there are facts that suggest that COVID-19 may affect male fertility. It is prudent for men of reproductive age who have recovered from COVID-19 to be evaluated for the presence of the virus in semen and fertility-related items. There is an urgent need to conduct quality studies on, in particular, the long-term effects of COVID-19 on the fertility of recovered males.

A Systematic Review of 571 Pregnancies Affected by COVID-19.

The outbreak of the novel coronavirus 2019 (COVID-19) disease has been severe and a cause for major concern around the world. Due to immunological and physiological changes during pregnancy, pregnant women have a higher risk of COVID-19 morbidity and mortality. The aim of this study was to collect and integrate the results of previous studies to get an accurate representation and interpretation of the clinical symptoms, laboratory and radiological findings, and characteristics of pregnant women with COVID-19. We conducted a scientific search in main databases with a combination of related MESH terms and keywords. The outcomes included common clinical symptoms at the time of onset of the disease, common laboratory and radiological findings, the rates of vaginal delivery and Cesarean section, Cesarean section indications, maternal complications, and vertical transmission rates. A total of 51 studies comprising 571 pregnant women with COVID-19 pneumonia were included in the study. The most common symptoms were fever, cough, and dyspnea, respectively. Elevated C-reactive protein and ground-glass opacities were the most common laboratory and radiological findings of COVID-19 pneumonia, respectively. A total of 114 Cesarean sections were performed due to COVID-19-related concerns. There were 55 cases of intubation (11.6%) and 13 maternal deaths (2.3%). The vertical transmission rate was 7.9%. We conclude that the characteristics of pneumonia caused by COVID-19 in pregnant women do not appear to be different from those in the general population with COVID-19 infections. However, pregnant women with underlying diseases were more likely to develop COVID-19 than others, and, in those infected with the virus, the rate of Cesarean delivery and preterm birth increased.

The 2019 Novel Coronavirus Disease in Pregnancy: A Systematic Review.

In December 2019, a respiratory disease caused by a coronavirus called SARS-CoV-2 (COVID-19) began in Wuhan, China, and quickly became a pandemic. In such situations, pregnant women are suspected of being among the vulnerable groups. The aim of this study was to report clinical symptoms, laboratory findings, and obstetrical complications, maternal, fetal, and neonatal complications of COVID-19 infection in pregnant women. We searched the Cochrane library, MEDLINE/PubMed, and Web of Sciences from their inception to April 5, 2020. Any study involving pregnant women with COVID-19 which evaluated the effect of the disease on pregnancy outcomes and fetal and neonatal complications was included in the study. The outcomes were the symptoms and laboratory findings, obstetrical complications, mode of delivery, and maternal, fetal, and neonatal complications. The search resulted in 69 titles and abstracts, which were narrowed down to 12 studies involving 68 women. The three most common symptoms of patients were fever, cough, and fatigue. The most common laboratory findings were an increase in C-reactive protein (CRP) and lymphopenia. The most common obstetrical complication was preterm labor (33.3%). No maternal deaths were reported. The Cesarean section rate was 83.3% and the vertical transition rate was 2.23%. The findings showed that the clinical symptoms and laboratory measures of pregnant women affected by COVID-19 did not differ from the general population. In general, the prognosis of mothers who suffered from COVID-19 and their newborns was satisfactory. However, there is a need for further rigorous studies to confirm these findings as the pandemic progresses.

A Systematic Review of the Assessment of the Presence of SARS-CoV-2 in Human Semen.

Theoretically, human testes are highly expressive organs for angiotensin converting enzyme 2 (ACE2), the SARS-CoV-2 receptor. This study aimed to investigate whether the causative agent of COVID-19 is found in semen. The databases of PubMed/MEDLINE, Scopus, Web of Science, and Google Scholar were searched using a combination of related keywords. All studies with original data, involving detection of SARS-CoV-2 in semen of male patients with COVID-19 or in those who have recovered from it, were included in the study. Six articles, including 136 samples, entered the systematic review. Most of the studies were performed in the recovery phase of COVID-19. In four articles, SARS-CoV-2 was not detected in semen, while in the other two articles semen testing showed the presence of the virus in some samples. Testicular discomfort, testicular cell damage, and spermogram disruption were also reported in some studies. We conclude that the study question cannot be answered with this number of studies. Since most of the samples were mild to moderate forms of COVID-19, it is not yet clear what the presence of the virus in semen will be in severe cases. The long-term effects are also vague. More original articles with better design and in different phases of the disease are needed to draw robust conclusions.

Effects of statins on preeclampsia: A systematic review.

BACKGROUND: Preeclampsia is a serious complication of pregnancy which increases the morbidity and mortality of both the fetus and pregnant woman. It is characterized by imbalances in angiogenesis, inflammation and endothelial dysfunction which cause the development of hypertension and proteinuria, sometimes progressing into a multisystem disorder. The aim of this systematic review was to analyze all the available data on statins and preeclampsia. METHOD: MEDLINE/PubMed, OVID, EMBASE, Web of Sciences, and SCOPUS were searched from inception to May 5, 2020. Any study evaluating the effects of statins on women with preeclampsia or HELLP syndrome or who were at risk for it has been included as well as the studies on the placenta of preeclamptic women. RESULTS: 12 articles which included 136 pregnant women and 35 placental samples from hypertensive and normotensive women were analyzed. They showed contradictory effects of statins on blood pressure in preeclampsia, on soluble FMS-like tyrosine kinase-1 (sFlt-1) as well as soluble endoglin (sEng). However, statins caused a significant dose-dependent reduction of sFlt-1 secretion from isolated cytotrophoblasts and an increased secretion of sEng (at least in some studies) in primary HUVECs and placental explants obtained from patients with preeclampsia. Statins also increased eNOS in preeclamptic placentas. Statins were beneficial for patients with antiphospholipid syndrome (APS) preventing preeclampsia and it seems that they might prevent complications of HELLP. CONCLUSION: It seems that statins might be beneficial for preventing or treating preeclampsia. Nevertheless, further studies are needed to provide definitive conclusions regarding these effects of statins.

Manifestations of COVID-19 in pregnant women with focus on gastrointestinal symptoms: a systematic review.

AIM: This review study was conducted to evaluate the symptoms of COVID-19 in pregnant women with a focus on gastrointestinal symptoms. BACKGROUND: COVID-19 is a fatal respiratory disease caused by a novel coronavirus that quickly became a pandemic. Although the main symptoms of this disease include respiratory symptoms, gastrointestinal manifestations have also been observed in some patients suffering from COVID-19. Pregnant women are among the most vulnerable groups in the community to infectious diseases. METHODS: Scientific databases were searched for articles published up to May 8, 2020. Any type of study investigating the manifestations of COVID-19 in pregnant women was included. Symptoms of the disease in pregnant women with an emphasis on gastrointestinal symptoms were assessed. RESULTS: The search resulted in 852 titles and abstracts, which were narrowed down to 43 studies involving 374 women. The most common symptoms of patients were fever (59.1%) and cough (48.4%), respectively. Gastrointestinal symptoms included diarrhea (4.5%), abdominal pain (1.6%), nausea (0.8%), and loss of appetite (0.3%), respectively. In studies on pregnant women with gastrointestinal symptoms, 13 fetal abortions occurred, most of which were induced abortions due to the risks posed by COVID-19.In thirty cases, and infected pregnant women reported a history of chronic pregnancy-related diseases. CONCLUSION: COVID-19 in pregnant women, similar to the general population, can present with gastrointestinal manifestations. The gastrointestinal tract can be a potential route for infection with the novel coronavirus.

A Systematic Review and Meta-Analysis of the Effect of Acupressure on Relieving the Labor Pain.

BACKGROUND: Numerous studies have been conducted on the effect of acupressure on labor pain, some of which have reported conflicting results. Thus, the present study was performed to critically review the previous studies related to the effect of acupressure administered during labor for relieving labor pain. MATERIALS AND METHODS: In this study, databases of the Cochrane Central Register of the Controlled Trials, PubMed/MEDLINE, Scopus, and Web of Science were searched from their establishment until November 5, 2019. All the Randomized Controlled Trials (RCTs) that had compared the use of acupressure with either placebo or nonintervention for relieving the labor pain were included in the study. Meta-analysis was performed using the Comprehensive Meta-Analysis (CMA) software Version 2. The random-effects model was used for pooling the effect sizes across the included studies. The p value <0.05 was considered as statistically significant. RESULTS: Totally, 5853 primary papers were identified in the search, which were narrowed down to 22 studies. The results of meta-analysis showed that the acupressure decreased the labor pain in the intervention group vs. control (-1.67 [-2.29 to -1.05], z = -5.25, p < 0. 001) (Q-value = 788.98, p < 0.001, I-squared = 96.83). No publication bias was found in the included studies (Egger's regression intercept = -1.02, p = 0.76). CONCLUSIONS: Although the findings of this meta-analysis showed that the acupressure significantly reduced the labor pain during the active phase of labor compared to the nonintervention or placebo; considering that the quality of the included studies was generally moderate, rigorous RCTs with better design and higher quality are needed to obtain definitive conclusions.

No Differences in Hematological Parameters of Fasting and Non-Fasting Pregnant Women Three Months after Ramadan.

Introduction: Ramadan is a holy month in the Islamic calendar. Ramadan fasting is a religious obligation for all healthy adult Muslims. Many pregnant Muslim women choose to fast during Ramadan while others prefer not to do so. The aim of this study was to compare the basic hematological parameters of fasting and non-fasting pregnant women 3 months after Ramadan. Materials and methods: In this case-control study, 3 months after the end of Ramadan, the concentrations of basic hematological parameters in 200 healthy pregnant women with a previous history of fasting (n = 100) and non-fasting (n = 100) were measured. Results: The results showed that the fasters and non-fasters were similar in maternal age, gestational age, gravidity, pre-pregnancy weight, and maternal weight at enrollment. There were no statistically significant differences between the mean of hemoglobin (12.34 ± 1.15 g/dL vs 12.60 ± 1.11 g/dL, p = 0.10) and hematocrit (36.39 ± 2.79 % vs 36.27 ± 3.14 %, p = 0.77) in the fasting and non-fasting groups, respectively. In addition, no statistically significant differences were observed between the two groups when other hematological parameters were compared (p >0.05). Conclusion: Although the immediate effects of Ramadan fasting on hematological parameters are not known, this study concluded that partial fasting during Ramadan from a hematological point of view is of no concern for pregnant women 3 months after the end of Ramadan.

Meta-analysis of the effect of acupressure on duration of labor and mode of delivery.

BACKGROUND: Acupressure is increasing in popularity as an alternative treatment in obstetrics and gynecology. OBJECTIVES: To summarize and assess evidence regarding the effects of acupressure on duration of labor and mode of delivery. SEARCH STRATEGY: Four major databases and Google Scholar were searched using terms related to labor and acupressure, without language restrictions, up to November 2015. SELECTION CRITERIA: Randomized controlled trials were included if they examined the effect of acupressure at any acupoint during childbirth on duration of labor and/or mode of delivery. DATA COLLECTION AND ANALYSIS: Two reviewers independently extracted data. The outcome measures were duration of labor and mode of delivery. Random-effects models were used to pool results. MAIN RESULTS: Thirteen studies were included in meta-analyses. Acupressure increased the chance of vaginal delivery when compared with placebo/no intervention (odds ratio [OR] 2.329, 95% confidence interval [CI] 1.348-4.024, P=0.002; risk difference [RD] 8.9%, 95% CI 2.7%-15.0%, P=0.005). Acupressure decreased the duration of the active phase by 1.310 hours (95% CI -1.738 to -0.882; P<0.001) and the second stage of labor by 5.808 minutes (95% CI -1.615 to -0.807; P<0.001). CONCLUSIONS: Acupressure could have a role in reducing the rate of cesarean delivery and decreasing the duration of labor in parturient women. However, there is a need for more reliable randomized controlled trials.

Effect of birth ball on labor pain relief: A systematic review and meta-analysis.

AIM: To critically evaluate the available evidence related to the impact of using a birth ball on labor pain relief. METHODS: The Cochrane library, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE/PubMed and Scopus were searched from their inception to January 2015 using keywords: (Birth* OR Swiss OR Swedish OR balance OR fitness OR gym* OR Pezzi OR sport* OR stability) AND (ball*) AND (labor OR labour OR Obstetric). All available randomized controlled trials involving women using a birth ball for pain relief during labor were considered. The search resulted in 341 titles and abstracts, which were narrowed down to eight potentially relevant articles. Of these, four studies met the inclusion criteria. Pain intensity on a 10 cm visual analogue scale was used as the main outcome measure. Risk of bias was assessed using the Cochrane Risk of Bias tool. Comprehensive Meta-Analysis Version 2 was used for statistical analysis. RESULTS: Four RCTs involving 220 women were included in the systematic review. One study was excluded from the meta-analysis because of heterogeneous interventions and a lack of mean and standard deviation results of labor pain score. The meta-analysis showed that birth ball exercises provided statistically significant improvements to labor pain (pooled mean difference -0.921; 95% confidence interval -1.28, -0.56; P = 0.0000005; I(2) = 33.7%). CONCLUSION: The clinical implementation of a birth ball exercise could be an effective tool for parturient women to reduce labor pain. However, rigorous RCTs are needed to evaluate the effect of the birth ball on labor pain relief.

Effect of hyoscine-N-butyl bromide rectal suppository on labor progress in primigravid women: randomized double-blind placebo-controlled clinical trial.

AIM: To determine the effects of hyoscine-N-butyl bromide (HBB) rectal suppository on labor progress in primigravid women. METHODS: A randomized double-blind placebo-controlled clinical trial was carried out on 130 primigravid women admitted for spontaneous labor. The women were recruited based on the inclusion and exclusion criteria and randomized into the experimental (n=65) and control group (n=65). In the beginning of the active phase of labor, 20 mg of HBB rectal suppository was administered to the experimental group, while a placebo suppository was administered to the control group. Cervical dilatation and duration of active phase and second stage of labor were recorded. RESULTS: The rate of cervical dilatation was 2.6 cm/h in the experimental and 1.5 cm/h in the control group (P<0.001). The active phase and the second stage of labor were significantly shorter in the experimental group (P=0.001 and P<0.001, respectively). There was no significant difference between the two groups in the fetal heart rate, maternal pulse rate, blood pressure, and the APGAR score 1 and 5 minutes after birth. CONCLUSION: Use of HBB rectal suppository in the active management of labor can shorten both the active phase and second stage of labor without significant side-effects.
