Subcutaneous vs intravenous fentanyl for labor pain management: a multicenter randomized controlled trial. Am J Obstet Gynecol MFM 2024; 6:101310. [PMID: 38342306 DOI: 10.1016/j.ajogmf.2024.101310] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 01/30/2024] [Accepted: 02/05/2024] [Indexed: 02/13/2024]
Abstract
BACKGROUND Labor pain is the most intense pain a woman will experience during her lifetime. Epidural anesthesia is recommended as the most effective method for pain relief, but it has several limitations. Fentanyl has high analgesic potency with short-acting duration, but the large-scale trials that assessed the effectiveness and safety of it for labor pain management are still limited. OBJECTIVE This study aimed to compare the effectiveness and harm and maternal satisfaction of subcutaneous vs intravenous fentanyl for labor pain management. STUDY DESIGN We conducted a multicenter, open-label randomized controlled trial. A total of 226 women were randomized to receive intravenous or subcutaneous fentanyl for labor pain management. Pain scores were evaluated before and after fentanyl administration at 5, 30, and 60 minutes and then every 60 minutes until delivery. The data were analyzed based on the intention-to-treat principle. RESULTS Both intravenous and subcutaneous fentanyl significantly decreased labor pain from baseline to delivery (overall mean change, -1.39; 95% confidence interval, -1.62 to -1.17; and -0.89; 95% confidence interval, -1.24 to -0.05, respectively). The reduction in the pain score between the 2 groups was not different (overall mean difference, -0.35; 95% confidence interval, -0.76 to 0.05). Maternal satisfaction was high for both intravenous and subcutaneous fentanyl (89.4% and 93.8%, respectively). There was no difference in the maternal satisfaction rate between the 2 groups (relative risk, 0.95; 95% confidence interval, 0.88-1.03). No serious maternal and neonatal adverse effects were observed. CONCLUSION Both intravenously and subcutaneously administered fentanyl were safe and significantly reduced pain from baseline to delivery among low-risk pregnancies. Maternal satisfaction with the childbirth experience was high regardless of the route of administration of fentanyl. No serious adverse effects of fentanyl were observed in either the mothers or the neonates.

Abstract
BACKGROUND Women of childbearing age feel great about giving birth, but the pain could be excruciating depending on their pain tolerances. Midwives requires obstetrical knowledge and skills such as pain management during labour and safety. We explored midwives' perspectives on the utilisation of pharmacological pain alleviation interventions during labour in selected hospitals in Matjhabeng Municipality, Free State province, South Africa. A qualitative study was undertaken, involving a sample of ten midwives, using a semi-structured interview guide. The interviews were audio-recorded and transcribed verbatim. Tesch's open coding data analysis method was applied to analyse the data. The midwives were restricted to use Pethidine and Phenergan prescribed by doctors for labour pain relief, which disrupted labour pain management and obliged them either to wait for a physician or follow telephone instructions. According to the midwives, women taking Pethidine and Phenergan encountered adverse effects and discomfort. Midwives identified high workload, inadequate personnel, lack of skill and knowledge, lack of medication availability, and lack of infrastructure as the primary challenges of administering pharmacological methods to women in labour. The lack of standing orders, which delays the administration of medications pending a physician's prescription, constituted an additional difficulty. In the instance that Pethidine and Phenergan were unavailable or ineffective for some women, the midwives recommended that women be administered alternative pharmacological pain relievers. They also advocated for institutionalization of pharmacological guidelines allowing them to use their discretion when treating labour pain. Midwives can only utilise a few standardised and regulated pharmacological medications for labour pain management. The midwives' ability to administer pharmacological pain relief during labour was hampered by a high workload burden, insufficient staff, lack of skill and understanding, drug unavailability, and inadequate infrastructure. Midwives advocated for supported guidelines that would allow them to treat labour pain at their discretion. Intersectoral stakeholders are required to improve midwife skills and attitudes. Health facilities need to train and supply analgesics to midwives. Midwives ought to be familiar with pharmacological pain relievers.

MEDICINA (KAUNAS, LITHUANIA) 2024; 60:143. [PMID: 38256403 PMCID: PMC10819130 DOI: 10.3390/medicina60010143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 01/02/2024] [Accepted: 01/10/2024] [Indexed: 01/24/2024]
Abstract
Background and Objectives: Long and ineffective labor causes hardships for mothers and doctors and increases the rate of cesarean sections and medical comorbidities. Several factors contribute to effective and less painful labor, including maternal age, parity, fetal characteristics, and the medications or procedures that obstetricians use for labor. We aimed to study the factors that affect labor duration and identify those that make labor more effective. Materials and Methods: This retrospective study included 141 patients who underwent normal vaginal deliveries at the Daegu Catholic University Medical Center between April 2013 and April 2022. Among the 141 patients, 44 received pethidine intravenously, 88 received oxytocin intravenously, and 64 received epidural anesthesia. The duration of the active phase and second stage of labor were recorded according to the findings of a manual examination of the cervix and continuous external electronic monitoring. We analyzed maternal and neonatal medical records and performed binomial logistic regression to identify the factors associated with a shorter active phase of labor. The clinical outcomes in mothers and neonates were also evaluated. Results: Among the various clinical factors, multiparity (odds ratio of parity 0.325) and the use of pethidine (odds ratio 2.906) were significantly associated with shortening the active phase of labor to less than 60 min. The use of epidural anesthesia or oxytocin was not significantly associated with reducing the active phase of labor. When patients were divided into two groups based on whether a pethidine injection had been used during labor, the duration of the active phase was shorter in the pethidine injection group than in the control group for both nulliparas and multiparas. No significant differences in the duration of the second stage of labor were observed between the pethidine injection and control groups. There were no significant differences in pregnancy outcomes, including the need for mechanical ventilation of neonates, Apgar scores, neonatal intensive care unit admissions, number of precipitous deliveries, maternal adverse side effects of drugs, or duration of maternal hospitalization between the two groups. Conclusions: Pethidine can be safely administered to women during labor to help reduce the duration of the active phase by promoting dilatation of the cervix and preventing complications that may result from prolonged labor. Pethidine may be helpful, especially for those who cannot receive epidural anesthesia or who cannot afford it. However, large-scale randomized controlled studies are required to evaluate the efficacy and safety of this drug during labor. Furthermore, it would be helpful if various studies were conducted depending on the timing of administration and indications for delivery.

Abstract
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.

Abstract
OBJECTIVE To assess the use of single dose of paracetamol intravenously in management of labour pains. BACKGROUND Pain during labour is a complex, subjective and multi-faceted physiological phenomenon that varies in intensity among women and is subjected to many social and cultural modifiers. SUBJECTS AND METHODS This randomized clinical study was conducted in Obstetrics and gynecology department from March 2019 to March 2020 including 96 primiparous women randomized into paracetamol group (n = 48) received 1000 mg of paracetamol IV infusion and pethidine group (n = 48) received 50 mg of pethidine given slowly IV. Primary outcome is the change of the intensity of perceived labor pain. Pain score was followed and recorded by visual analogue scale (VAS). Our study protocol was registered at ClinicalTrials.gov; NCT04744727. RESULTS VAS score was highly significant improved gradually after 30 min, 1, 2 and 3 h of paracetamol and pethidine taken compared at start study, but participants in paracetamol group had lower pain after 2 and 3 h (3.92 ± 1.42 and 5.69 ± 1.07) than those of the pethidine groups (4.42 ± 1.87 and 5.38 ± 1.34). Also, 2.1% of paracetamol group developed dizziness and 4.2% developed nausea and vomiting, while there was 29.2% of pethidine group developed dizziness and 37.5% developed nausea and vomiting. CONCLUSIONS Intravenous paracetamol as labour analgesia is effective, safe, inexpensive, available and with no maternal or fetal side effects as compared to Pethidine. Paracetamol needs to have more chance in comparison to other forms as a labour pain analgesia, especially in our communities.
