The comparison of the effect of non-pharmacological pain relief and pharmacological analgesia with remifentanil on fear of childbirth and postpartum depression: a randomized controlled clinical trial.

INTRODUCTION: Childbirth may be associated with psychological, social, and emotional effects and provide the background for women's health or illness throughout their life. This research aimed at comparing the impact of non-pharmacological pain relief and pharmacological analgesia with remifentanil on childbirth fear and postpartum depression. MATERIALS AND METHOD: This randomized clinical trial with two parallel arms was conducted on 66 women with term pregnancy referred to Taleghani Hospital in Tabriz for vaginal delivery during September 2022 to September 2023. First, all of the eligible participants were selected through Convenience Sampling. Then, they were randomly assigned into two groups of pharmacological analgesia with remifentanil and non-pharmacological analgesia with a ratio of 1:1 using stratified block randomization based on the number of births. Before the intervention, fear of childbirth (FOC) was measured using Delivery Fear Scale (DFS) between 4 and 6 cm cervical dilatation. Pain and fear during labor in dilatation of 8 cm were measured in both groups using VAS and DFS. After delivery, FOC was assessed using Delivery Fear Scale (W DEQ Version B) and postpartum depression using the Edinburgh's postpartum depression scale (EPDS). Significance level was considered 0.05. Mean difference (MD) was compared with Independent T-test and ANCOVA pre and post intervention. RESULTS: The mean score of FOC in the non-pharmacological analgesia group was significantly lower than that in the pharmacological analgesia group after the intervention by controlling the effect of the baseline score (MD: -6.33, 95%, Confidence Interval (CI): -12.79 to -0.12, p = 0.04). In the postpartum period, the mean score of FOC in the non-pharmacological analgesia group was significantly lower than that in the pharmacological analgesia group after controlling the effect of the baseline score (MD: -21.89; 95% CI: -35.12 to -8.66; p = 0.002). The mean score of postpartum depression in the non-pharmacological analgesia group was significantly lower than that in the pharmacological analgesia group (MD: -1.93, 95% CI: -3.48 to -0.37, p = 0.01). TRIAL REGISTRATION: Iranian Registry of Clinical Trials (IRCT): IRCT20170506033834N10. Date of registration: 05/07/2022 Date of first registration: 05/07/2022. URL: https://www.irct.ir/trial/61030; Date of recruitment start date05/07/2022. CONCLUSION: The study results indicated a reduction in FOC and postpartum depression among parturient women receiving non-pharmacological strategies with active participation in childbirth compared to women receiving pharmacological analgesia. Owing to the possible side effects of pharmacological methods for mother and fetus, non-pharmacological strategies with active participation of the mother in childbirth are recommended to reduce the FOC and postpartum depression.

Simple Yet Effective-Sterile Water Injections to Treat Labor Pain in the Transport Environment.

Sterile water injections (SWI) is a nonpharmacologic pain relief option to treat back pain in labor. This case report describes and discusses the use of SWI in the context of an obstetric retrieval of a 29-year-old woman who was transferred by the Royal Flying Doctor Service South Eastern Section. It provides an overview of SWI, discusses the relevance for medical transport, and offers suggestions for medical transport professionals.

Socio-economic disadvantage and utilisation of labour epidural analgesia in Scotland: a population-based study†.

Socio-economic deprivation is associated with adverse maternal and childhood outcomes. Epidural analgesia, the gold standard for labour analgesia, may improve maternal well-being. We assessed the association of socio-economic status with utilisation of epidural analgesia and whether this differed when epidural analgesia was advisable for maternal safety. This was a population-based study of NHS data for all women in labour in Scotland between 1 January 2007 and 23 October 2020, excluding elective caesarean sections. Socio-economic status deciles were defined using the Scottish Index of Multiple Deprivation. Medical conditions for which epidural analgesia is advisable for maternal safety (medical indications) and contraindications were defined according to national guidelines. Of 593,230 patients in labour, 131,521 (22.2%) received epidural analgesia. Those from the most deprived areas were 16% less likely to receive epidural analgesia than the most affluent (relative risk 0.84 [95%CI 0.82-0.85]), with the inter-decile mean change in receiving epidural analgesia estimated at -2% ([95%CI -2.2% to -1.7%]). Among the 21,219 deliveries with a documented medical indication for epidural analgesia, the socio-economic gradient persisted (relative risk 0.79 [95%CI 0.75-0.84], inter-decile mean change in receiving epidural analgesia -2.5% [95%CI -3.1% to -2.0%]). Women in the most deprived areas with a medical indication for epidural analgesia were still less likely (absolute risk 0.23 [95%CI 0.22-0.24]) to receive epidural analgesia than women from the most advantaged decile without a medical indication (absolute risk 0.25 [95%CI 0.24-0.25]). Socio-economic deprivation is associated with lower utilisation of epidural analgesia, even when epidural analgesia is advisable for maternal safety. Ensuring equitable access to an intervention that alleviates pain and potentially reduces adverse outcomes is crucial.

Association of pain catastrophizing with labor pain and analgesia consumption in obstetrical patients.

INTRODUCTION: Pain catastrophizing is an exaggerated negative orientation to painful stimuli which in obstetric patients is associated with fear of overwhelming labor pain and negative pain-related outcomes. This study aimed to quantitatively examine the association of pain catastrophizing with maternal labor pain outcomes. METHODS: We conducted a prospective observational study of women admitted for a vaginal trial of labor. Subjects completed the 13-item Pain Catastrophizing scale (PCS) questionnaire (scored 0 to 52, higher scores representing greater catastrophizing). Pain was assessed at baseline and at request for neuraxial labor analgesia. Labor and postpartum pain intensity was assessed as the average area under the pain intensity by time curve. Pain at request for analgesia, labor pain, postpartum pain, analgesic consumption, and quality of recovery was compared between high (PCS ≥ 17) and low catastrophizing groups. RESULTS: Data from 138/157 (88%) subjects were included in the analysis. Median (IQR) pain scores at request for analgesia were 9 (8,10) and 8 (6,9), a difference of 1 (95% CI 0 to 2.5, P = 0.008) in high-catastrophizing and in low-catastrophizing groups, respectively. Adjusted pain during labor, postpartum pain and opioid analgesic use were not significantly different. High-catastrophizers reported less comfort, ability to mobilize and less control during hospitalization. Post-discharge there were no differences in pain or analgesic use. CONCLUSION: We did not observe greater labor or post-delivery pain or increased analgesic use in high-catastrophizing parturients. High catastrophizers reported greater pain when requesting analgesia, which is consistent with the role of catastrophizing in intensifying the experience of pain.

Beyond Fear: Unveiling the Relationship Between Fear of Childbirth and Pharmacological Pain Relief.

BACKGROUND: Pharmacological analgesia is the dominant method for pain relief in labor. Fear of childbirth (FOC) may significantly affect women's preferences for and usage of pharmacological analgesia. AIM: This study aimed to investigate the relationship between FOC in late pregnancy and preferences for, as well as actual use of, pharmacological analgesia among nulliparous and multiparous women, accounting for confounding factors. METHODS: A total of 1,300 women participated in the study, completing questionnaires assessing preferences for pharmacological analgesia, FOC, perception of labor pain, social support, coping styles, and demographic variables. The actual use of pharmacological analgesia was followed up. The data were analyzed using univariate and multivariate regression analyses. RESULTS: Univariate analysis revealed that women with moderate to severe FOC had a stronger preference for pharmacological analgesia compared to those with none to mild FOC. However, multivariate analysis showed no direct association between FOC and actual usage of pharmacological analgesia. Instead, a stronger preference for pharmacological analgesia increased the likelihood of its actual usage during labor. CONCLUSIONS: Our study underscores the effect of FOC on preferences for pharmacological analgesia and its potential influence on actual usage during labor. Healthcare providers should consider women's FOC and preferences when evaluating pain management options. Targeted interventions focusing on promoting non-pharmacological techniques should be implemented to optimize labor pain management for women, particularly nulliparous women.

Anesthesia practices for management of labor pain and cesarean delivery in France (EPIDOL): A cross-sectional survey.

BACKGROUND: This study aimed to collect obstetric anesthesia practice and patient-reported outcomes as an update to the last French Obstetric Anesthesia survey from 1996. METHODS: Maternity units were randomly selected across France and surveyed for 7 consecutive days from February, 2016, to January, 2017. Data was gathered prospectively by questionnaires filled out by patients and anesthesia providers. RESULTS: There were 1885 questionnaires received from 56 units, with 379 cesarean delivery (CD) and 1506 vaginal delivery (VD) cases analyzed. The overall neuraxial labor analgesia (NLA) rate was 82.5% (95% CI [82.4-82.6]), with 70.3% (95% CI [71.4-71.6]) receiving automated administration (PCEA/PIEB). NLA was effective throughout labor in 68.2% of cases, however, severe pain was reported by 29.4% of patients. The overall rate of alternative approaches for labor analgesia was 19.5% (95%CI [19.2-19.7]). Obesity (OR 2.8; 95% CI [1.0-7.5], p < 0.04) and delivery in level I units (OR 0.6; 95% CI [0.5-0.9], p < 0.01) were associated with severe pain during VD. Satisfaction was found to be similar in patients delivering with or without NLA. The incidence of pain during CD was similar in scheduled versus non-scheduled CD. Failure of NLA during CD was associated with severe pain (OR 10.0; 95% CI [3.1-31.9], p < 0.01) and dissatisfaction (OR 26.2; 95% CI [3.0-225.1], p < 0.01). CONCLUSION: Despite the high NLA rate in France, a significant proportion of women experience severe pain during labor and delivery. This study emphasizes the need for further practice guidelines in obstetric anesthesia to ensure optimal pain management and improve patients' experience during childbirth.

Factors associated with the intention of pregnant women to give birth with epidural analgesia: a cross-sectional study.

BACKGROUND: In Belgium most women receive epidural analgesia during labour. Although, it offers satisfactory pain relief during labour, the risk on a series of adverse advents has been reported. The objective of this study was to determine factors associated with the intention of pregnant women, anticipating a vaginal birth, of requesting epidural analgesia during labour. METHODS: A cross-sectional study, using an online self-report questionnaire was performed, including socio-demographic and personal details. Associated factors were examined with the HEXACO-60 questionnaire, the Mental Health Inventory-5, the Tilburg Pregnancy Distress Scale and the Labour Pain Relief Attitude Questionnaire for pregnant women. The level of intention to request epidural analgesia was based on two questions: Do you intend to ask for epidural analgesia (1) at the start of your labour; (2) at some point during labour? Data were collected predominantly during the second and third trimester of pregnancy. Descriptive analysis and a multiple linear regression analysis were performed. RESULTS: 949 nulliparous (45.9%) and multiparous (54.1%) pregnant women, living in Flanders (Dutch-speaking part of Belgium) anticipating a vaginal birth completed the questionnaires. Birth-related anxiety (ß 0.096, p < 0.001), the attitude that because of the impact of pregnancy on the body, asking for pain relief is normal (ß 0.397, p < 0.001) and feeling more self-confident during labour when having pain relief (ß 0.034, p < 0.001) show a significant positive relationship with the intention for intrapartum epidural analgesia. The length of the gestational period (ß - 0.056, p 0.015), having a midwife as the primary care giver during pregnancy (ß - 0.048, p 0.044), and considering the partner in decision-making about pain relief (ß - 0.112, p < 0.001) show a significant negative relationship with the intention level of epidural analgesia. The explained variability by the multiple regression model is 54%. CONCLUSIONS: A discussion during pregnancy about the underlying reason for epidural analgesia allows maternity care providers and partners to support women with pain management that is in line with women's preferences. Because women's intentions vary during the gestational period, pain relief should be an issue of conversation throughout pregnancy.

Association between breakthrough labor pain, patient-controlled epidural analgesia use, and numeracy: A pilot observational study.

OBJECTIVE: Labor analgesia can be maintained with a continuous epidural infusion, supplemented by patient-controlled epidural boluses. patient-controlled epidural boluses use and timing require numeric understanding, as patients need to understand when they can administer supplemental boluses, lockout intervals, and total doses. We hypothesized that women with lower numeric literacy have a higher rate of provider-administered supplemental boluses for breakthrough pain because they do not understand the concept behind patient-controlled epidural boluses. DESIGN: Pilot observational study SETTING: Labor and Delivery Suite PARTICIPANTS: Nulliparous, English-speaking patients with singleton, vertex pregnancies admitted for postdates (gestational age ≥ 41 weeks) induction of labor requesting neuraxial labor analgesia. INTERVENTIONS: Combined spinal-epidural labor analgesia was initiated with intrathecal fentanyl and epidural analgesia was maintained using continuous epidural infusion with patient-controlled epidural boluses. MEASUREMENTS AND FINDINGS: Numeric literacy was assessed using the Lipkus 7-item expanded numeracy test. Patients were stratified by whether or not they required supplemental provider-administered analgesia and patient-controlled epidural boluses use patterns were evaluated. A total of 89 patients completed the study. There were no demographic differences between patients who required supplemental analgesia compared with those who did not. Patients that required supplemental analgesia were more likely to request and receive patient-controlled epidural boluses (P<0.001). Hourly bupivacaine requirement was higher in women with breakthrough pain. There were no differences in numeric literacy between the two groups. KEY CONCLUSIONS: Patients who required treatment of breakthrough pain had higher patient-controlled epidural boluses demands-to-delivery ratio. Numeric literacy was not correlated with the need for provider-administered supplemental boluses. IMPLICATIONS FOR PRACTICE: Easy to understand scripts on how to use patient-controlled epidural boluses allows for understanding of patient-controlled epidural boluses use.

Effects of epidural analgesia on the course of labor.

OBJECTIVE: The aim of this study was to assess the effects of epidural analgesia on the course of labor. SUBJECTS AND METHODS: The material for the study was obtained from the analysis of 300 medical records of patients delivering under epidural analgesia in the period 2015-2019. A questionnaire by the authors was used as the research tool. Statistical analysis was performed using Fisher's test, Pearson's Chi-square test of independence, and Cramer's V-test. RESULTS: The first stage of labor in primiparas usually lasted six to nine hours, and in multiparas under five hours (p = 0.041). The second stage was shorter in multiparas (p < 0.001). Our five-year analysis demonstrated that the second stage of labor was longer from year to year (p = 0.087). The fetal station had an effect on the duration of the first stage of labor (p = 0.057). After administration of epidurals, the majority of the women bore the pain well (p = 0.052). CONCLUSIONS: Epidural analgesia reduces labor pain, but may also disturb the natural rhythm of labor. This happens even if the moment of application of the analgesia is chosen with the guidance of obstetric indications, and may result in the necessity for surgical intervention.

Pharmacologic and nonpharmacologic options for pain relief during labor: an expert review.

Labor pain is among the most severe types of physical pain that women may experience during their lifetime. Thus, pain relief is an essential part of medical care during childbirth. Epidural analgesia is considered to be the most efficient method of pain relief during labor. Nevertheless, patient preferences, contraindications, limited availability, and technical failure may require the use of alternative pain reliving methods during labor including systemic pharmacologic agents, and nonpharmacologic methods. Nonpharmacologic methods for pain alleviation during vaginal birth have become popular over the years, either as a complement to pharmacologic agents or at times as the principal therapy. Methods such as relaxation techniques (ie, yoga, hypnosis, and music), manual techniques (ie, massage, reflexology, and shiatsu), acupuncture, birthing ball, and transcutaneous electrical nerve stimulation are considered safe, although the evidence supporting their effectiveness for pain relief is not as robust as it is for pharmacologic agents. Systemic pharmacologic agents are mostly administered by inhalation (nitrous oxide) or through the parenteral route. These agents include opioids such as meperidine, nalbuphine, tramadol, butorphanol, morphine, and remifentanil, and non-opioid agents such as parenteral acetaminophen and nonsteroidal anti-inflammatory drugs. Systemic pharmacologic agents suggest a diverse armamentarium of medication for pain management during labor. Their efficacy in treating pain associated with labor varies, and some continue to be used even though they have not been proven effective for pain relief. In addition, the maternal and perinatal side effects differ markedly among these agents. There is a relative abundance of data regarding the effectiveness of analgesic drugs compared with epidural, but the data regarding comparisons among the different types of alternative analgesic agents are scarce, and there is no consistency regarding the drug of choice for women who do not receive epidural pain management. This review aims to present the available data regarding the effectiveness of the different methods of relieving pain during labor other than epidural. The data presented are mainly based on recent level I evidence regarding pharmacologic and nonpharmacologic methods for pain relief during labor.

Acute pain and analgesic requirement after vaginal childbirth with and without neuraxial labor analgesia-Retrospective cohort study.

BACKGROUND: Few data are available on the intensity of pain that women experience during the first five days after vaginal childbirth. Moreover, it is unknown if the use of neuraxial labor analgesia has any impact on the level of postpartum pain. METHODS: We performed a retrospective cohort study based on chart review of all women who delivered vaginally at an urban teaching hospital between April 2017 and April 2019. The primary outcome was the area under the curve of pain score on numeric rating scale (NRS) documented in electronic medical records for five days postpartum (NRS-AUC5days). Secondary outcomes included peak NRS score, doses of oral and intravenous analgesics consumed during the first five days postpartum, and relevant obstetric outcomes. Logistic regression was used to examine the associations between the use of neuraxial labor analgesia and pain-related outcomes adjusting for potential confounders. RESULTS: During the study period, 778 women (38.6%) underwent vaginal delivery with neuraxial analgesia and 1240 women (61.4%) delivered without neuraxial analgesia. Median (Interquartile range) of NRS-AUC5days was 0.17 (0.12-0.24) among women who received neuraxial analgesia and 0.13 (0.08-0.19) among women who did not (p<0.001). Women who received neuraxial analgesia were more likely to require the first- and second-line analgesics postpartum than women who did not: diclofenac (87.9% vs. 73.0%, p< 0.001, respectively); acetaminophen (40.7% vs. 21.0%, p< 0.001, respectively). The use of neuraxial labor analgesia was independently associated with increased odds of having NRS-AUC5days in the highest 20 percentile (adjusted odds ratio [aOR] 2.03; 95% confidence interval [CI] 1.55-2.65), having peak NRS ≥ 4 (aOR 1.54; 95% CI 1.25-1.91) and developing hemorrhoids during the postpartum hospitalization (aOR 2.13; 95% CI 1.41-3.21) after adjusting for relevant confounders. CONCLUSION: Although women who used neuraxial labor analgesia had slightly higher pain scores and increased analgesic requirement during postpartum hospitalization, pain after vaginal childbirth was overall mild. The small elevation in the pain burden in neuraxial group does not seem to be clinically relevant and should not influence women's choice to receive labor analgesia.

The effect of ylang oil and lemon oil inhalation on labor pain and anxiety pregnant women: A randomized controlled trial.

BACKGROUND: and purpose: To date, there has been very limited experimental research on the impact of ylang ylang oil and lemon oil inhalation labor pain. This study was conducted to investigate the effects of aromatherapy, one of the non-pharmacological pain methods, on anxiety and labor pain in the active phase in primiparous pregnant women. METHODS: A randomized controlled trial design was used in the study, which was conducted with 45 primiparous pregnant women. Volunteers were randomized into the lemon oil group (n = 15), ylang-ylang oil group (n = 15), and control group (n = 15) by using the sealed envelope method. The visual analog scale (VAS) and the state anxiety inventory were applied to the intervention and control groups before the application. After the application, the VAS and the state anxiety inventory were applied at 5-7 cm dilatation and the VAS was applied alone at 8-10 cm dilatation. The trait anxiety inventory was applied to the volunteers after delivery. RESULTS: The mean pain scores at 5-7 cm dilatation in the intervention groups (lemon oil 6.90, ylang ylang oil, 7.30) were significantly lower than in the control group (9.20) (p = 0.005). There was no significant difference between the groups in terms of their mean pre-intervention and 5-7-cm-dilatation anxiety scores (p = 0.750; p = 0.663), mean trait anxiety scores (p = 0.094), and mean first-and fifth-minute Apgar scores (p = 0.051; p = 0.051). CONCLUSION: It was found that aromatherapy applied by inhalation at labor reduced the perception of labor pain but had no effect on anxiety.

Determining the effect of inhalation and lavender essential oil massage therapy on the severity of perceived labor pain in primiparous women: A randomized controlled trial.

BACKGROUND: This research aimed to reveal the effect of lavender essence inhalation and the massage therapy applied with lavender oil on the severity of labor pain of primiparous women. METHODS: This randomized controlled trial was conducted with three groups. Pregnant women participating in the study were randomly divided into control group (n=40), lavender essence inhalation group (n=44) and lavender essence massage (n=37) groups. The applications were divided in three for each phase in the first stage of labor (early, active and transition). Thereafter sacral compression and circular massage were applied for 15 minutes on the lower back (waist) region of the participants by using 2 drops of lavender oil in each phase of labor; 2 drops of lavender oil were dripped onto the palms of the participants in the inhalation group by the researcher and they were asked to inhale it for 3 minutes. Research data were collected using Personal Information Form (PIF), Visual Analogue Scale (VAS) and Postpartum Assessment of Women Survey (PAWS). RESULTS: The results of the research revealed that the labor pain perceived by the women who were applied inhalation and massage therapy using lavender essential oil were milder compared to the control group (p<0.05). Another finding of the research revealed that the lavender oil inhalation gave the best results in the latent phase, however the massage therapy with lavender oil was more effective in the active and transition phases. CONCLUSION: Inhalation and massage therapy applied using lavender essential oil contributed to the alleviation of perceived labor pain. For this reason, massage therapy and inhalation applications using lavender oil are recommended to be applied by midwives as a complementary method to adapt to labor pain during delivery.

Comparison of intravenous paracetamol infusion versus intramuscular tramadol as labor analgesia: a randomized control trial.

PURPOSE: Labor pain is one of the most agonizing pains experienced by all delivered women. Many pharmacological agents used in labor analgesia require intense monitoring facilities, which are not available in routine obstetric practice in low-resource settings. This study aimed to compare the efficacy of intravenous (IV) paracetamol and intramuscular (IM) tramadol on labor pain relief, labor progression, and maternal and neonatal outcomes. METHODS: This randomized drug trial was carried out on 110 women divided into two groups. Group A women received 1000 mg of IV paracetamol, and Group B women received 100 mg of IM tramadol during the active phase of labor. Pain intensity was assessed by the Visual Analogue Scale (VAS) at intervals till 120 min of delivery. The maternal and neonatal outcomes were recorded. RESULTS: There was a statistically significant fall in pain score till 180 min of drug administration in the paracetamol group and 120 min in the tramadol group. At 180 min and 240 min, paracetamol is more effective than tramadol (p value 0.004 at 180 min and 0.0119 at 240 min). There were significantly low pain score levels at 60 min of delivery in the paracetamol group (p value-0.004). Nausea and vomiting were significantly higher in the tramadol group (p value 0.000013). CONCLUSION: Compared to IM tramadol, IV paracetamol has a longer duration of action and fewer maternal side effects, making it suitable for parenteral analgesia in labor. Due to a better safety profile, there is no need for intense maternal and fetal monitoring with IV paracetamol.

Fentanyl for labour pain management: a scoping review.

BACKGROUND: Labour pain has been identified as an important reason for women to prefer caesarean section (CS). Fentanyl is one of the short acting opioids recommended by World Health Organization for pain relief during labour. This study aimed to identify and describe the available evidence on the use of fentanyl (monotherapy) for labour pain management by any routes of administration or regime. METHODS: We included the records published until 31 December 2021 which reported administration of fentanyl to women with normal labour for labour pain relief. Data were extracted by one reviewer and checked by another reviewer using a standardised agreement form. We mapped and presented data descriptively in figure and tabular format. RESULTS: We included 51 records from 49 studies in our scoping review. The studies were conducted in 12 countries, mostly high-income countries. The study designs of the 51 included records were varied as follows: 38 (74.5%) experimental studies (35 randomised controlled trials and three quasi-experimental studies), and 12 (23.5%) observational studies (five retrospective cohort studies, four prospective cohort studies, two retrospective descriptive studies, and one descriptive study) and one qualitative study. Of the included records, six used intranasal fentanyl, five used subcutaneous fentanyl, 18 (35.3%) used intravenous fentanyl, 18 (35.3%) used intrathecal fentanyl, and nine used epidural fentanyl. Many records compared fentanyl with another analgesic agent while five records (9.8%) had no comparison group and seven records (13.7%) compared with no analgesia group. The doses of fentanyl varied by routes, study and the requirement depended on the women. Pain assessment was the most frequent outcome measure presented in the records (78.4%). Only nine records (17.6%) investigated women's satisfaction about labour pain relief using fentanyl and seven records (13.7%) reported the effect of fentanyl on breastfeeding. The most common reported neonatal outcomes were foetal heart rate (33 records, 64.7%) and Apgar score (32 records, 62.7%). CONCLUSION: There is limited primary evidence especially randomised controlled trials to evaluate the effectiveness and harms of different routes of fentanyl in low- or middle-income countries. There is a need for high-quality research to establish the most effective route of fentanyl and associated effects for evidence-based international guidelines.

Should remifentanil patient-controlled analgesia be a routine choice for pain relief in labour?

Patient-controlled analgesia with remifentanil is usually reserved for patients for whom other forms of pain relief are contraindicated. However, remifentanil patient-controlled analgesia reduces the likelihood of needing an epidural and therefore the risk associated with it, provides good pain relief compared to other options, and the risks can be mitigated with appropriate management.

[Cultural myths on the use of analgesia in labor: A cross-sectional study in Nigerian women]. / Mitos culturales sobre el uso de la analgesia en el trabajo de parto: estudio transversal en mujeres nigerianas.

OBJECTIVE: Pain is termed as a subjective phenomenon, however almost all women acknowledge that labor pain is the most severe form of pain a woman experiences in her lifetime. Obstetric analgesia is underutilized in developing countries due to cultural myths and taboos. Hence, the present study aims to identify Nigerian women's knowledge of labor analgesia and to explore what myths and factors hinder with the use of analgesia in labor. METHOD: A quantitative descriptive cross-sectional design was adopted in this study. The population of the study predominantly consisted of pregnant women from the «Yoruba ethnic group¼. An adapted semi-structured questionnaire was used to obtain data from participants from selected Health Care Centers in Ekiti state, Nigeria. The collected data was analyzed using a descriptive and inferential statistics and was represented in form of tables and charts with level of significance set at p ≤ 0.05. RESULTS: A total of 236 respondents were included in the study (n = 236). Findings from this study revealed that, the participants showed very poor knowledge on labor pain management strategies, with only 26.3% being aware of pain management strategies used in relieving labor pain. An elevated number of the participants (56.8%) believed that labor pain should not be relieved with the use of drugs, strongly agreeing that analgesia was «a sign ofweakness¼ (57.2%). Also, more than half (51.7%) of participants had fears that pain relief administered during labor can cause harm to the unborn baby. Belief that experiencing labor pain completes one's motherhood (49.6%), Religion (50.4%) and Culture (54.5%), were reported as factors influencing the uptake/acceptance of labor analgesia among participants. Furthermore statistical significant association was found between educational level of participants and knowledge of labor analgesia among participants (p value = 0.000; p ≤ 0.05). CONCLUSIONS: Cultural myths on the use of analgesia exist among participants. It is suggested that women-centered education should be targeted toward eliminating these myths and increasing awareness about labor analgesia.

Transcutaneous Electrical Nerve Stimulation for Post-Cesarean Birth Pain Control: A Randomized Controlled Trial.

OBJECTIVE: To evaluate whether transcutaneous electrical nerve stimulation (TENS) reduces opioid use after cesarean birth. METHODS: We conducted a randomized, double-blind, placebo-controlled trial of TENS after cesarean birth, with the primary outcome of opioid use during the first 60 hours postoperatively. Secondary outcomes included pain scores and satisfaction with pain control on each postoperative day, duration of postoperative hospitalization, and adverse effects of TENS. We estimated 60 patients in each arm for 80% power to detect a 25% decrease in opioid use, assuming 10% attrition. To assess for a placebo effect, an additional 60 patients were randomized to no TENS during recruitment for secondary analyses comparing opioid use, pain scores, and pain control satisfaction between no TENS and placebo TENS. Analysis was by intention-to-treat. RESULTS: From January 2020 through March 2021, we enrolled 180 participants-60 per group. Baseline characteristics were similar across groups. Median (interquartile range) opioid consumption in the first 60 hours postoperatively, in morphine milligram equivalents, was 7.5 (0-30) with active TENS and 0 (0-22.5) with placebo TENS (P=.31). There were no significant differences in pain scores, satisfaction with pain control, or postoperative length of stay. In the no TENS group, median (interquartile range) opioid consumption in the first 60 hours postoperatively was 7.5 (0-21.9), similar to that in the placebo group (P=.57). There were also no significant differences in pain scores or pain control satisfaction between participants allocated to no TENS and those allocated to placebo TENS. CONCLUSION: Use of TENS after cesarean birth did not change hospital opioid consumption, pain scores, or length of postoperative stay. There was no evidence for a placebo effect of TENS on opioid use or pain scores. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov: NCT04399707. FUNDING SOURCE: Cardinal Health.

Beyond the epidural: Alternatives to neuraxial labor analgesia.

Labor creates an intense pain experienced by women across the world. Although neuraxial analgesia is the most effective treatment of labor pain, in many cases, it may not be undesired, not available, or have contraindications. In addition, satisfaction with labor analgesia is not only determined by the efficacy of analgesia but a woman's sense of agency and involvement in the childbirth experience are also key contributors. Providing safe choices for labor analgesia and support is central to creating a tailored, safe, and effective analgesic treatment plan with high maternal satisfaction. Healthcare provider knowledge of various nonneuraxial analgesic options, including efficacy, contraindications, safe clinical implementation, and side effects of various techniques is needed for optimal patient care and satisfaction. Future rigorous scientific studies addressing all of these labor analgesia options are needed to improve our understanding. This review summarizes the current published literature for commonly available non-neuraxial labor analgesic options.

Factors associated with women's preferences for labor epidural analgesia in Singapore: a survey approach.

Epidural analgesia provides effective pain relief during labor. However, there is limited information on the factors associated with pregnant women's preferences for labor epidural analgesia (LEA) prior to labor onset. We performed a secondary analysis of a clinical trial to identify demographic characteristics, pain and psychological vulnerability factors associated with preferences for LEA. Pregnant women at ≥ 36 weeks' gestation prior to labor and delivery were recruited and given questionnaires on their LEA preferences, psychological and pain vulnerabilities. The primary outcome was the association between pre-delivery Edinburgh Postnatal Depression Scale (EPDS) with cut-off ≥ 10 and LEA preference. Of the 250 women recruited, 51.6% (n = 129) indicated "yes to LEA". Amongst those considering LEA as an option to reduce labor pain, women who preferred to use LEA (n = 129) indicated favorable or neutral opinion. Additionally, 68% (n = 82) from those "no to LEA" or "not sure about LEA" still gave either favorable or neutral opinion for LEA (p < 0.0001). The multivariate logistic regression analysis found that EPDS ≥ 10 (p < 0.01), occupation (p = 0.03), ethnicity (p < 0.01), state anxiety (p = 0.02), mode of current pregnancy (unplanned; planned, assisted; planned, natural; p = 0.03) and premenstrual anger/irritability before current pregnancy (p = 0.02) were associated with LEA preference. The findings may help to define the population that may require further education on considering LEA and allow early identification on different LEA preferences to provide patient centric care prior to labor and delivery.
