Nursing Clinical Practice Guide
Clinical Scenario: You are the triage nurse in the ED. A 32-year-old construction worker is brought in by coworkers, holding a wet cloth over his right eye. He states cement dust containing "lime" blew into his eye about 45 minutes ago. He is in visible distress.
Nursing Intervention Strategy:- 1Immediate Action (Do NOT wait for physician orders)Don personal protective equipment (PPE) and immediately initiate continuous irrigation. Use a Morgan Lens or IV tubing connected to a 1L bag of Normal Saline (NS). Hold the eyelids open to ensure irrigation reaches all conjunctival folds (fornices).
- 2Assessment During IrrigationAfter initiating irrigation, obtain a focused history (chemical agent, time of exposure, any first aid given). Assess visual acuity roughly (can he count fingers?). Inspect for the critical finding: corneal opacity (cloudy/white spot on the normally clear cornea) and test corneal reflex by gently touching the cornea with a wisp of cotton (expect a blink; absence is a red flag).
- 3Monitoring & EvaluationCheck conjunctival pH every 15-30 minutes using pH paper. Continue irrigation until pH is neutral (7.4). Anticipate orders for topical antibiotics, cycloplegics (to reduce pain from ciliary spasm), and steroids (to reduce inflammation). Prepare for urgent ophthalmology consultation.
Patient Safety and Precautions:
• Contraindication: Never attempt to neutralize an alkali with an acid, as the heat produced by the chemical reaction can cause further thermal injury.
• Key Monitoring: Intraocular pressure (IOP) can rise secondary to inflammation. Monitor for signs of acute glaucoma (severe pain, nausea, halo vision).
• Medication Caution: Topical steroids can impair healing and increase risk of infection; they must be used under strict ophthalmologic supervision.
Nursing Procedure & Medication Flow
Emergency Eye Irrigation Procedure:
1. Position patient supine with head turned to affected side.
2. Place a basin against the cheek to catch irrigation fluid.
3. Use your fingers to hold eyelids open against the orbital bone.
4. Irrigate from the inner canthus (nasal side) to the outer canthus to avoid washing contaminant into the other eye.
5. Irrigate for at least 30 minutes for alkaline burns, or until pH is normal.
6. Document: time irrigation started/stopped, solution used, volume used, pH readings, and patient's response.
A Word from Your Senior Nurse
"In the ED, a chemical burn to the eye is one of the few true 'stop everything and irrigate NOW' emergencies. Don't get distracted by the patient's vital signs or registration paperwork. Your swift action with that liter of saline can literally save their sight. Remember, with alkalis, the damage continues as long as the chemical is in contact with the tissue. So, irrigate, irrigate, irrigate! And when you study, link the pathophysiology – liquefactive necrosis and deep penetration – directly to the clinical sign: a cloudy cornea. That connection will help you choose the right answer every time."
