Labor pain management practices and associated factors in Ethiopia: A systematic review and meta-analysis

BACKGROUND

The pain that women experience during labor and childbirth is the central feature of parturition in humans. Despite improvement in the development of standards for pain assessment and treatment, labor pain is mostly ignored especially in low- and middle-income countries resulting in unmeasured suffering from childbirth for mothers.

OBJECTIVES

We aimed to provide a comprehensive estimation of the pooled magnitude and associated factors of labor pain management practices in Ethiopian public health facilities.

SEARCH STRATEGY

A systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. Electronic databases including Google Scholar, Web of Science, Excerpta Medica Database (EMBASE), PubMed/MEDLINE, and Scopus were searched from database inception to June 30, 2023.

SELECTION CRITERIA

The inclusion criteria were established prior to article review and follows the population, intervention, comparison and outcome criterions.

DATA COLLECTION AND ANALYSIS

We evaluated publication bias by means of funnel plots and Egger's test. Heterogeneity between studies was assessed using I2 statistics. For each associated factors in meta-regressions, the pooled odds ratio (OR) and its 95% confidence interval (CI) were extracted. A P value of 0.05 was used to determine the significance of the small study effect.

MAIN RESULTS

Our search terms yielded 17 studies with 5735 participants. The pooled prevalence of labor pain management practices in Ethiopia was 45.73% (95% CI: 39.13, 52.32; I2 = 96.4). Having adequate knowledge regarding labor pain management (OR: 3.74; 95% CI: 2.74, 5.11; I2 = 53.8%), a favorable attitude toward labor pain management (OR: 2.90; 95% CI: 2.03, 4.14; I2 = 63.8%), availability of labor analgesics (OR: 3.23; 95% CI: 2.18, 4.79; I2 = 46.2%), and clinical experience of 10 or more years (OR: 3.45; 95% CI: 2.06, 5.78; I2 = 19.0%) were factors that were statistically associated with the use of labor pain management practices.

CONCLUSION

We concluded that the routine practices of labor pain management by obstetric health providers in Ethiopia are still low. Therefore, it remains important to call for holistic and inclusive interventions targeting maternity health providers and hospital officials to update their long-standing practices.

The effectiveness of aromatherapy in the management of labor pain: A meta-analysis

One non-pharmacological method that can be used to safely and without negative side effects is aromatherapy. This meta-analysis study was carried out to assess the effectiveness of aromatherapy in the treatment of labor pain. The analysis included 14 randomized controlled trials of aromatherapy interventions for labor pain. In the studies, it was observed that aromatherapy was applied through massage and inhalation using oils such as lavender, jasmine, rose, chamomile, bitter orange, and boswellia. In the meta-analysis, it was discovered that aromatherapy had a beneficial effect on the management of labor pain and reduced labor pain in the intervention group in 11 studies; it was found that there was no effect in 3 studies. According to analysis findings, aromatherapy significantly lessened the intensity of labor pain. The study's findings support the notion that aromatherapy can lessen labor pain.

Peanut Ball Utilization Protocols in Women During Labour and Delivery: An Integrative Review

OBJECTIVE

This review aimed to assess the evidence available in the literature about the protocols for using peanut ball (PB) in women during labour and delivery.

DATA SOURCES

A systematic search was carried out by 2 independent researchers in the PubMed/MedLine, Web of Science, Embase, Cochrane and Scopus databases, and the reference lists were scanned for additional articles.

STUDY SELECTION

Search terms employed were selected from MeSH (Medical Subject Headings) and DeCS (Descriptors in Health Sciences) and combined in each database: "Pregnant Women" AND "Peanut Ball", "Peanut Ball" AND "Labor, Obstetric", as well as "Peanut Ball" AND "Parturition". There were no limits regarding the publication period or language. Studies that answered the following question were included: What are the protocols for the use of the PB in women during labour and childbirth described in the literature? Secondary studies were excluded. Disagreements were resolved by a third researcher.

DATA EXTRACTION

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement guided this review. The authors prepared a standardized data extraction sheet to extract data and used the Mendeley software to organize the analyzed studies.

DATA SYNTHESIS

Ten studies made up the final sample of this review. Eight articles presented the protocol for using the PB: 2 studies included it after epidural analgesia and removed it at complete cervical dilation and effacement; 4 addressed the frequency of position changes during labour; and 3 reported data on maternal positions that were adopted. Five studies showed lower rates of cesarean delivery, and 2 reported that PB reduces the length of labour. Only 1 article associated the use of PB with the reduction of instrumental deliveries and perineal lacerations. One study showed a positive evaluation of parturients regarding the use of PB.

CONCLUSION

PB was associated with a reduction in cesarean and instrumental deliveries, and the length of labour. Despite its benefits, there is no standardized protocol for the use of PB, preventing it from predicting outcomes with its use.

Efficacy and safety of non-pharmacological interventions for labour pain management: A systematic review and Bayesian network meta-analysis

AIMS AND OBJECTIVES

To compare and rank the efficacy and safety of non-pharmacological interventions in the management of labour pain.

BACKGROUND

Recently, various non-pharmacological interventions have been applied to manage labour pain and have shown positive effects. However, evidence identifying which type of non-pharmacological intervention is more efficient and safer is limited.

DESIGN

Systematic review and Bayesian network meta-analysis based on PRISMA-NMA.

METHODS

Seven databases were searched from database inception-March 2020. Two reviewers independently performed study selection, quality appraisal and data extraction. Conventional meta-analysis was conducted using either fixed-effects model or random-effects model according to statistical heterogeneity. The Bayesian network meta-analysis was conducted using the consistency model.

RESULTS

43 studies involving nine non-pharmacological interventions were included. The Bayesian network meta-analysis showed that acupressure (SMD = -2.00, 95% CrI -3.09 to -0.94), aromatherapy (SMD = -2.01, 95% CrI -3.70 to -0.35) and massage therapy (SMD = -1.26, 95% CrI -2.26 to -0.30) had significant positive effects on alleviating labour pain, with aromatherapy being the most effective. The results also revealed that yoga (SMD = -130.85, 95% CrI -212.01 to -59.32) and acupressure (SMD = -10.14, 95% CrI -20.24 to -0.41) were the most effective interventions for shortening the first stage and the second stage of labour, respectively. There were no significant differences between non-pharmacological interventions and usual care or placebo control on the use of pharmacological methods and neonatal 5-min Apgar score.

CONCLUSIONS

The evidence in this network meta-analysis illustrates that non-pharmacological interventions are effective and safe for labour pain management in low-risk pregnant women. In the future, well-designed studies are needed to validate the conclusion of this network meta-analysis.

RELEVANCE TO CLINICAL PRACTICE

The results support the use of non-pharmacological interventions, especially aromatherapy and acupressure, to relieve labour pain in low-risk pregnant women. Non-pharmacological interventions for labour pain management are recommended to apply according to maternal women's preference and values.
