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.

[PMID: 32522156 PMCID: PMC7285553 DOI: 10.1186/s12871-020-01063-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Accepted: 06/01/2020] [Indexed: 11/26/2022] Open
Abstract
Background Loss of resistance (LOR) technique is a widely used method to identify the epidural space. However, cases of inadequate epidural anesthesia in cesarean section were frequently reported. Also, the success rate of epidural anesthesia with LOR technique varied depending on the proficiency of the practitioner. The purpose of this study was to assess the efficacy and safety of electrical stimulation to identify epidural spaces in cesarean section for novices or clinicians with recent gap in experience. Methods Pregnant women scheduled for elective cesarean section were randomly allocated to two groups. Groups were classified based on the methods used for identifying the epidural space: the LOR group (group L) and the LOR with epidural electrical stimulation group (group E). Clinicians with less than 10 epidural cesarean section experiences in the recent year performed epidural anesthesia for cesarean section. In the group E, a RegionalStim® conductive catheter was inserted through the Tuohy needle, and the guidewire passing through the catheter was connected to a peripheral nerve stimulator. The intensity of the stimulation was gradually increased from 0.25 mA to 1.5 mA until paresthesia was elicited and radiated. We assessed the success of epidural anesthesia (complete success, partial success or failure). Other clinical parameters including maternal satisfaction, time required for epidural anesthesia, neonatal Apgar scores, pain scores and adverse events were compared between the two groups. Results Except for 6 patients who withdrew consent, 54 patients were enrolled in this study (28 for the group L and 26 for the group E). The demographic data showed no difference between the two groups. There was no adverse event resulted from electrical stimulation. The group E showed higher rate of complete success, sensitivity in finding epidural space and maternal satisfaction compared to the group L (21/26 vs. 15/28, p = 0.034, 0.96 vs. 0.68, p = 0.012 and 4.04 vs. 3.39, p = 0.02, respectively). The other clinical parameters showed no differences between the two groups. Conclusion In addition to the conventional LOR technique, identifying epidural spaces using electrical stimulation led to better outcomes without additional risks for novices as well as clinicians with recent gap in experience. Trial registration This study was retrospectively registered in the ClinicalTrials.gov Registry (NCT03443466) on February 23, 2018.
