Title: Can Ear Acupressure Help Relieve Kidney Stone Pain Faster When Combined with Painkillers?

Purpose

This study tests whether adding ear acupressure to standard painkillers (NSAIDs) helps adults with kidney stone pain feel better faster. The investigators also want to know if this combination causes any side effects.

Key Questions:

Does ear acupressure + NSAIDs reduce pain more quickly than NSAIDs alone? Are there any safety concerns with this treatment? How does real ear acupressure compare to a fake (placebo) procedure? Who Can Join? Adults aged 18-75 Experiencing moderate-to-severe kidney stone pain (confirmed by CT or ultrasound) No recent painkiller use or allergies to NSAIDs

What Participants Will Do:

Receive in the emergency room:

Real treatment: Tiny needles placed on 3 ear points + NSAIDs (ketorolac injection) OR Placebo treatment: Fake tape on ear points + NSAIDs (same injection) Rate their pain on a 0-10 scale over 60 minutes. Have their heart rate and blood pressure checked.

Study Details:

Duration: Single ER visit (no long-term follow-up) Participants Needed: 116 Safety: Rescue pain medication (like morphine) is available if needed.

Why This Matters:

Kidney stones cause severe pain, and current painkillers may not work fast enough. Ear acupressure is a low-risk method from traditional Chinese medicine that could provide quicker relief.

Ethics

Approved by Changhai Hospital's Ethics Committee. Participants can leave the study anytime.
