简要总结

This pilot study aims to assess the feasibility, acceptability, and effectiveness of using nitrous oxide (N2O) sedation for intrauterine device (IUD) insertions for nulliparous adolescent and young adult women in a primary care clinic setting.

详细描述

The objective of this research study is to learn more about how to make the intrauterine device (IUD) insertion procedure more comfortable. IUDs are highly effective at preventing pregnancy and are also used to treat gynecological conditions such as endometriosis or heavy periods. Unfortunately, many adolescents and young adults do not get an IUD because the insertion procedure can be painful. Currently, there are no medications that successfully reduce pain during IUD insertion for adolescents in the outpatient clinic setting.

We plan to study if nitrous oxide sedation is a feasible strategy for improving the IUD insertion experience for adolescents and young adult women. Although nitrous oxide is already used to manage pain and anxiety in other medical settings (such as for pain during labor or dental procedures), nitrous oxide sedation has not been rigorously studied for IUD insertions in teenagers and young adults.

During phase one of our study ("pre-implementation phase"), study participants will receive current standard of care (ibuprofen) for managing pain during IUD insertions. In phase two ("post-implementation phase"), study participants will receive nitrous oxide sedation in addition to ibuprofen during IUD insertions. We will survey study participants to assess the feasibility, acceptability, and effectiveness of nitrous oxide sedation for IUD insertions in the primary care clinic setting.

This study will help clinicians understand whether nitrous oxide could be a practical and effective way to manage pain and anxiety for adolescents during IUD insertion procedures. Ultimately, we hope this study will lead to increased satisfaction with the IUD insertion procedure and increased use of this highly effective method of contraception among adolescents.

研究组 & 干预措施

Inhaled nitrous oxide anesthesia

Experimental

Patients will be assigned to a "pre-implementation" (control) group or a "post-implementation" (treatment) group. The first twelve participants will be the control group and the next twelve participants will be the treatment group. The treatment group will receive inhaled N2O/O2. All participants will receive pre-procedural standard of care for IUD insertions, including 400-600 mg ibuprofen orally at least 20 minutes prior to insertion to reduce post-procedure pain. The N2O will be gradually up-titrated to a goal ratio of 70/30 N2O/O2. N2O/O2 will be administered per Boston Children's Hospital (BCH) N2O sedation protocol. Prior to speculum placement, treatment group participants will receive the inhaled gas until minimal sedation is achieved per BCH sedation guidelines, such that the patient is cooperative, oriented, and tranquil. Inhaled N2O will be administered throughout the duration of the procedure.

干预措施: Nitrous oxide gas for inhalation (Drug)

Inhaled oxygen placebo

Placebo Comparator

Patients will be assigned to a "pre-implementation" (control) group or a "post-implementation" (treatment) group. The first twelve participants will be the control group and the next twelve participants will be the treatment group. The control group will receive inhaled O2 alone. All participants will receive pre-procedural standard of care for IUD insertions, including 400-600 mg ibuprofen orally at least 20 minutes prior to insertion to reduce post-procedure pain. Control group participants will receive 100% O2 for two minutes prior to speculum placement. Inhaled oxygen will be administered throughout the duration of the procedure.

干预措施: Oxygen Gas for Inhalation (Drug)

结局指标

主要结局

Anesthetic acceptability: Proportion reporting that inhaled nitrous oxide anesthesia should be available for IUD procedures

Procedural satisfaction: VAS

时间窗: Immediately after intervention/procedure

Median visual analog scale (VAS) score for procedural pain management satisfaction, with scores ranging from 0 to 100 with 0=completely satisfied to 100= completely dissatisfied

Pain management satisfaction:
