Rings are usually removed to prevent ischemia of a digit. Remove a ring if the digit shows any signs of neurovascular compromise such as decreased capillary refill, decreased pulse wave on pulse oximetry, mottling, paleness, paresthesias, or diminished sensation. Rings should be removed whenever patients complain that a ring is causing pain. Generally, even a tight-fitting ring will not be painful. Rings must be removed from any injured digit where edema is a possible consequence. Examples include sprains, contusions, fractures, lacerations, crush injuries, and burns. Rings should be removed from all digits on the involved side for any extremity injury above the digits and where edema of the distal extremity is a possible consequence. Other nontraumatic conditions that may necessitate emergent ring removal include infections of the upper or lower extremity, acute increases in volume status, and allergic reactions. A patient may present and request a ring be removed that is tight and can no longer be taken off. Consider the need for urgent ring removal with markedly decreased levels of consciousness and in all critically ill patients, particularly those being admitted to intensive care settings or undergoing emergent surgery.
