The aim of performing this study was comparison of Entonox and transcutaneous electrical nerve stimulation (TENS) in labor pain in Zanjan city, Iran.
This clinical trial study was conducted on 120 pregnant women in Zanjan-Iran, 2016. The patients were randomly divided (by method of 1:1:1) into three groups (each group 40 patients): First group was TENS group; the second group was Entonox group and control group were choose from the patients that had a physiological delivery. They did not want to use analgesia. All the analyses were done using SPSS (version 23).
Before intervention the pain severity between three group was relatively same ( = .78). After intervention, pain score was significantly higher in control group compared to other two groups ( = .005), but the differences between mean Apgar score between three groups was not significant ( = .59). Also, both Entonox and TENS had significantly lower pain compared control group ( = .005), but there was no significant difference between Entonox and TENS in regard of pain score ( = .997).
Our findings reported that two groups of Entonox and TENS had similar effect on pain relief and decreased significantly pain scores. Therefore, TENS methods as a non-drug pain relief method can propose to women for relief of labor pain.
本研究旨在比较恩诺酮和经皮电神经刺激（TENS）在伊朗赞詹市分娩疼痛中的效果。
这是一项 2016 年在伊朗赞詹市进行的临床试验研究，共纳入 120 名孕妇。患者被随机分为三组（每组 40 名患者）：第一组为 TENS 组；第二组为恩诺酮组；对照组为选择那些自然分娩、不使用镇痛药物的患者。所有分析均使用 SPSS（版本 23）进行。
干预前，三组患者的疼痛严重程度相当（ = .78）。干预后，对照组的疼痛评分明显高于其他两组（ = .005），但三组间的平均 Apgar 评分差异无统计学意义（ = .59）。此外，恩诺酮和 TENS 组的疼痛评分均明显低于对照组（ = .005），但两组间的疼痛评分差异无统计学意义（ = .997）。
我们的研究结果表明，恩诺酮和 TENS 两组在缓解疼痛方面效果相似，均能显著降低疼痛评分。因此，TENS 作为一种非药物镇痛方法，可以向产妇推荐用于缓解分娩疼痛。
