Root Cause

Supraorbital pressure (thumb over the supraorbital notch) can cause orbital fracture in patients with facial trauma or skull base fractures, and can trigger a vagal response (bradycardia, hypotension) in some patients; trapezius squeeze or nail bed pressure are safer alternatives.

眶上压力（拇指按压眶上切迹）可能对存在面部创伤或颅底骨折的患者造成眶骨骨折，并可能在某些患者中引发迷走神经反应（心动过缓、低血压）；斜方肌挤压或甲床压力是更安全的替代方法。

Workarounds

  1. 92% success Use the trapezius squeeze: pinch the trapezius muscle (upper shoulder) between thumb and index finger, twisting 90 degrees. Hold for 10 seconds. Observe for eye opening, verbal response, or motor response. This is the preferred safe stimulus per current ATLS guidelines.

  2. 88% success Use nail bed pressure: apply pressure to the nail bed of a finger or toe with a pen or blunt object (e.g., the handle of a reflex hammer). Avoid using a needle or sharp object. Hold for 5-10 seconds.

Dead Ends

Common approaches that don't work:

  1. Use a pen or hard object to apply pressure to the supraorbital ridge 95% fail

    Hard objects increase fracture risk and can cause skin laceration; only fingertips should be used, and even then risk exists.

  2. Apply bilateral supraorbital pressure simultaneously for stronger stimulus 85% fail

    Bilateral pressure increases risk of vagal response (bradycardia, syncope) and does not improve reliability of GCS scoring.

  3. Use sternal rub as the primary painful stimulus for GCS 70% fail

    Sternal rub can cause bruising and is less standardized; it may also elicit a spinal reflex rather than cortical response.
