Abstract
Objective
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.
Study design
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.
Results
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).
Conclusions
The majority of eligible women agreed to participate in this study evaluating an uncommon
pain control intervention.
