Abstract

STUDY OBJECTIVE: To evaluate the impact of nitrous oxide on patient-reported pain for placement of intrauterine systems (IUSs) in adolescents STUDY DESIGN: : Prospective observational study SETTING: : IUS placement in an ambulatory clinic compared with placement with nitrous oxide in a hospital-based sedation unit PARTICIPANTS: : English-speaking adolescents aged 12 to 20 presenting to a pediatric and adolescent gynecologist with a medical indication for IUS placement MAIN OUTCOME MEASURES: : Patient-reported procedural pain measured on a visual analog scale 2 minutes post IUS insertion procedure. Secondary outcome measurement of likelihood of recommending an IUS to a peer.

RESULTS: Seventy-four patients agreed to participate. Forty-five patients underwent IUS placement in the clinic. Controlling for age, history of dysmenorrhea, and body mass index, a significant time (change in reported pain scores pre- vs post IUS insertion) by treatment (nitrous oxide vs standard of care) interaction was observed for patient-reported pain (b = -29.32 mm, P < 0.01). Patients receiving nitrous oxide were more likely to recommend an intrauterine placement than patients who received the current standard of care for pain management (b = 0.47, P = 0.02) after controlling for age, baseline pain score, and dysmenorrhea history.

CONCLUSION: Patient-reported pain was attenuated for patients who received nitrous oxide relative to those who received standard IUS placement. Patient-reported satisfaction was higher for patients who received nitrous oxide relative to those who received standard IUS placement.
