Nursing Clinical Practice Guide
Clinical Scenario
You are triaging in the ED. A construction worker runs in holding his right eye, yelling, "Cement dust got in my eye!" He is in significant pain, photophobic, and keeping the eye tightly closed.
Nursing Intervention Strategy
1. Immediate Action (Priority): Do not try to pry the eye open. Quickly guide the patient to a treatment room with an eye irrigation station. Use a Morgan Lens or IV tubing connected to a 1L bag of Normal Saline (NS) to begin continuous irrigation. If unavailable, have the patient lie supine and turn his head to the side; use a 500ml-1L bag of NS or sterile water to pour a steady stream over the eye, from the inner canthus outward, while using your fingers to hold the eyelids open (wear gloves!).
2. Concurrent Assessment: While setting up or during irrigation, ask: "What was the chemical? How long ago? Were safety glasses on?" Check the pH of the conjunctival cul-de-sac with litmus paper every 5-10 minutes during irrigation.
3. Post-Irrigation Care: After 20-30 minutes and a neutral pH is confirmed, perform a more formal assessment: visual acuity, slit-lamp exam (by MD/RNP), and instill prescribed cycloplegic drops (to reduce pain from ciliary spasm) and antibiotic ointment. Apply a loose eye patch if the cornea is abraded.
4. Patient Education & Disposition: Arrange urgent ophthalmology follow-up. Educate on signs of infection or worsening vision. Reinforce the absolute necessity of safety goggles.
Patient Safety and Precautions
- Key Point! Never neutralize a chemical burn with another chemical (e.g., don't use vinegar on an alkali burn). This can cause a heat-producing reaction and more damage.
- Ensure irrigation fluid flows from the nasal side (medial canthus) to the temporal side (lateral canthus) to avoid flushing contaminates into the other eye or the nasolacrimal duct.
- For severe burns or burns involving large areas of the face, monitor for airway compromise due to edema or inhalation injury.
Nursing Procedure & Medication Flow
Procedure: Emergency Eye Irrigation
1. Explain Quickly: "I need to wash your eye out immediately to prevent blindness. This will help with the pain too."
2. Position: Supine, head turned to affected side over a basin.
3. Irrigate: Use IV tubing or bag with a steady stream. Hold eyelids open with gloved fingers.
4. Duration/Endpoint: Irrigate for minimum 20-30 min. Check pH; goal is 7.0-7.5. Continue if pH remains alkaline (>7.5).
5. Document: Time irrigation started/stopped, solution used, volume used (e.g., "2L NS"), pH readings, patient tolerance, and pre/post visual acuity if possible.
Medication Caution: Topical antibiotics (e.g., erythromycin ointment) and cycloplegics (e.g., homatropine) are used after irrigation. Corticosteroids are controversial and used only under strict ophthalmology guidance due to risk of worsening corneal melting.
A Word from Your Senior Nurse
In the chaos of the ED, it's easy to get caught up in the "what" and "how" of the accident. Your nursing brain must instantly switch to "STOP THE DAMAGE." For a chemical eye burn, your hands should be reaching for the saline bag as your mouth is asking the first question. This reflexive prioritization saves vision. When you study, don't just memorize "irrigate eye." Picture the scenario, feel the urgency, and understand the "why" – because every second of delay means more corneal cells are irreversibly destroyed. That deep understanding is what makes you not just an NCLEX passer, but a nurse who patients can truly rely on in a crisis.
