## 문제

A client presents to the emergency department with a penetrating ear injury from a metal object. Which nursing intervention should be the priority?

## 보기

1. Remove the foreign object immediately to prevent further damage
2. Irrigate the ear canal with normal saline to clean the wound
3. Stabilize the object in place and avoid manipulation **✔ 정답**
4. Apply direct pressure to the ear to control bleeding

**정답: 3**

## 해설

For penetrating ear injury, priority is to stabilize the object in place to prevent further damage to delicate ear structures. Removing or irrigating can cause complications like hearing loss.

Understanding the Priority in Penetrating Ear Injury

When a client presents with a penetrating injury where a foreign object is still impaled in the ear, the immediate priority is stabilization and prevention of secondary injury. The correct intervention is to stabilize the object in place and avoid manipulation.

Pathophysiology and Clinical Rationale

The ear’s anatomical proximity to the skull base and major vessels makes this a high-risk injury. A penetrating metal object can act as a tamponade, applying direct pressure to lacerated blood vessels. Removing the object prematurely can dislodge this natural clot, leading to sudden, uncontrolled hemorrhage. More critically, the object may have penetrated beyond the external ear into deeper structures.

The case report by Hopper et al. highlights the severe consequences of penetrating trauma in this region, noting that operatively managed penetrating carotid trauma carries a mortality rate approaching 20% [1]. This underscores that what appears to be an external ear injury could involve the intracranial carotid artery or other critical neurovascular structures. Manipulating or removing the object outside of a controlled surgical environment risks converting a contained injury into a catastrophic bleed or causing a stroke from an embolic event.

Why Other Options Are Incorrect

-   Option 1 (Remove the foreign object immediately): This is contraindicated. Blind removal can sever vessels that the object is currently occluding and cause uncontrollable bleeding or further damage to the delicate middle and inner ear structures.

-   Option 2 (Irrigate the ear canal): Irrigation is dangerous with an unknown depth of penetration. Fluid can be forced into the middle ear or cranial vault if the tympanic membrane is ruptured or the object has breached the temporal bone, potentially causing infection or neurovascular injury.

-   Option 4 (Apply direct pressure): Applying direct pressure to an ear with an impaled object can push the object deeper, exacerbating the injury to underlying structures. If bleeding is present, pressure should be applied around the object, not on it.

Emergency Nursing Management

The emergency department management of maxillofacial trauma, which includes penetrating ear injuries, demands a systematic approach that prioritizes life-threatening conditions before addressing the wound itself . The nursing priority is to stabilize the foreign body with bulky dressings to prevent any movement during patient transport and diagnostic imaging. The patient must be prepared for a controlled surgical exploration, often involving a multidisciplinary team including otolaryngology and possibly neurosurgery, as illustrated by the combined surgical approach required for successful management of penetrating trauma near the carotid artery [1]. Definitive removal and vascular repair must occur in the operating room where immediate hemorrhage control is possible.References (research sources)

## 임상 시나리오

Clinical Practice Guide: Penetrating Ear Injury with Impaled Object

Immediate Priority Actions

- **Do not remove the object.** The impaled object may be providing a tamponade effect on lacerated vessels, and removal can precipitate catastrophic hemorrhage or stroke.

- **Stabilize the object manually.** Use bulky dressings or gauze rolls placed around the object to prevent movement during transport or patient repositioning. Secure the dressings with tape, ensuring no pressure is applied directly to the object itself.

- **Assess for neurovascular compromise.** Monitor for signs of cerebrovascular injury, including altered mental status, unilateral weakness, facial droop, or clear fluid drainage from the ear (otorrhea), which may indicate a basilar skull fracture.

Contraindicated Interventions

- **Irrigation or wound cleansing:** Any fluid instillation can dislodge the object or introduce contaminants deeper into the wound.

- **Direct pressure on the object:** This risks pushing the object deeper, converting a contained injury into an open vascular injury.

- **Blind probing or manipulation:** Do not attempt to visualize the depth or trajectory of the wound in the emergency department setting.

Definitive Management Pathway

- **Immediate surgical consultation** (otorhinolaryngology and/or vascular surgery). The object must be removed under controlled conditions in the operating room with the capability for immediate hemorrhage control and vascular repair.

- **Imaging prior to surgery:** A CT angiogram is typically indicated to map the object's trajectory and identify any vascular involvement, particularly of the internal carotid artery or jugular vein.

- **Prophylactic antibiotics and tetanus prophylaxis** should be initiated as ordered due to the high risk of infection from a contaminated metal object.

## 핵심 개념

- **Tamponade effect** — The direct pressure an impaled object exerts on lacerated blood vessels, acting as a plug to control bleeding.
- **Penetrating carotid trauma** — An injury where an object pierces the carotid artery, carrying a mortality rate approaching 20% and risk of massive hemorrhage or stroke.
- **Embolic event** — The blockage of a blood vessel by a dislodged clot or foreign material, a risk if a penetrating object is moved from a vascular injury site.
