Initiating Intrapartum Nitrous Oxide in an Academic Hospital: Considerations and Challenges.

A 50%-50% mixture of nitrous oxide and oxygen has long been used for managing pain during labor in many countries, but only recently has this intrapartum analgesic technique become popular in the United States. Nitrous oxide is considered minimal sedation and a safe pain management alternative. Many facilities are now interested in providing laboring women this analgesic option. The process of establishing use of nitrous oxide in a large institution can be complicated and may seem daunting. This brief report describes the challenges that occurred during the process of initiating nitrous oxide for pain management during childbirth at an academic medical center and discusses various committee roles. Nurses at the University of New Mexico Hospital now directly oversee the administration of nitrous oxide to women in labor in accordance to an established guideline. Despite limited available research, the guideline also allows offering nitrous oxide as a pain management technique for women with opioid dependence. Key components of the guideline and specifics related to education, cost, and safety are reviewed.

A clinical audit of the number of vaginal examinations in labor: a NOVEL idea.

INTRODUCTION: Clinical practice audits present an opportunity for providers to examine and reflect on their practice. Vaginal examinations are an integral part of intrapartum care but can be uncomfortable for women and can increase the risk of chorioamnionitis. Thus, vaginal examinations should be performed thoughtfully and for necessary reasons. METHODS: A busy midwifery service at a large academic center underwent an audit of the number of vaginal examinations performed in labor for 205 women admitted in spontaneous labor or with spontaneous rupture of membranes. The retrospective chart audit was performed by research midwives who queried 2 electronic medical record databases, 1 for provider progress notes and 1 for nursing notes. RESULTS: On average, a woman underwent 4 vaginal examinations during labor, a rate greater than the World Health Organization recommendation of 1 examination every 4 hours during the first stage. The rate of presumed chorioamnionitis in this group of healthy, low-risk women was 6%, and women with this diagnosis averaged 7 vaginal examinations. DISCUSSION: After presentation and discussion of the audit findings, the midwives expressed appreciation for the opportunity to explore such a fundamental element of clinical practice and a heightened awareness of the importance of performing and documenting vaginal examinations. Audits of a similar nature in other midwifery practices are needed, as are studies exploring rates and possible modifiable causes of chorioamnionitis in low-risk women.
