Intraprocedural Superior Hypogastric Nerve Block Allows Same-Day Discharge following Uterine Artery Embolization

Area of Science:

• Interventional Radiology
• Pain Management
• Vascular Interventions

Background:

• Uterine artery embolization (UAE) is a common procedure for various gynecological conditions.
• Effective pain control is crucial for successful outpatient UAE and patient satisfaction.
• Traditional pain management may involve significant opioid use and longer recovery times.

Purpose of the Study:

• To evaluate the efficacy and safety of superior hypogastric nerve block (SNHB) for pain control during elective outpatient UAE.
• To assess the impact of SNHB on the need for patient-controlled analgesia (PCA) pumps and opioid consumption.
• To determine the effect of SNHB on the length of stay after UAE.

Main Methods:

• Retrospective case-control study of 39 patients undergoing elective outpatient UAE.
• Superior hypogastric nerve block (SNHB) was utilized for pain management.
• Data collected on technical success of SNHB, PCA use, opioid requirements, and length of stay.

Main Results:

• Technical success rate for SNHB was 87%.
• 97% of patients receiving SNHB did not require a PCA pump.
• Median opioid requirement was low (7.5 MME) for those needing analgesia.
• Median length of stay was 2.2 hours, facilitating same-day discharge.

Conclusions:

• Superior hypogastric nerve block (SNHB) is a safe and effective method for pain management in outpatient UAE.
• SNHB significantly reduces the need for opioid analgesia and PCA pumps.
• This technique allows for shorter recovery periods and same-day discharge, improving patient throughput and experience.
