石膏（Cast）若過緊會壓迫血管與神經，導致腔室症候群（Compartment syndrome）。評估應遵循「6P」原則：Pain（疼痛）、Pallor（蒼白）、Pulselessness（無脈搏）、Paresthesia（感覺異常）、Paralysis（麻痺）、Poikilothermia（溫度異常）。肢體冰冷與蒼白是血液灌流不足的直接徵象。
Coolness and pallor of the toes are early signs of compromised arterial perfusion, indicating potential neurovascular impairment such as compartment syndrome. These findings require immediate assessment and intervention to prevent permanent tissue damage.
