The objective was to determine feasibility of a study comparing mean pain scores between women randomized to nitrous oxide/oxygen (NO) versus oxygen+oral analgesics for trimester surgical abortion.
Pilot randomized controlled trial comparing NO (n=10) versus oxygen+oral analgesics (n=10). Feasibility of subject recruitment, and pain and satisfaction scores on a visual analog scale were evaluated.
Fifty-seven percent of eligible women participated. Mean pain scores were similar between groups, and mean satisfaction scores were higher for the NO group (77.5 vs. 46.7, P=.048).
The majority of eligible women agreed to participate in this study evaluating an uncommon pain control intervention.
本研究旨在确定一项比较接受一氧化二氮/氧气(NO)与氧气加口服镇痛药的女性在孕中期人工流产时平均疼痛评分的研究的可行性。
先导性随机对照试验,比较NO组(n = 10)和氧气加口服镇痛药组(n = 10)。评估了受试者招募的可行性,以及视觉模拟量表上的疼痛和满意度评分。
57%符合条件的女性参与了研究。两组的平均疼痛评分相似,NO组的平均满意度评分更高(77.5对46.7,P = 0.048)。
大多数符合条件的女性同意参与这项评估一种不常见疼痛控制干预措施的研究。
