Osmosis from Elsevier - Neonatal eye prophylaxis: Nursing pharmacology
Neonatal eye prophylaxis is a preventive measure against ophthalmia neonatorum, an eye infection in newborns often caused by Neisseria gonorrhoeae or Chlamydia trachomatis. These infections are typically transmitted during vaginal delivery or can occur in utero after membrane rupture. The condition presents as conjunctivitis with symptoms like eye redness, edema, and purulent discharge within 2 to 5 days of life. Untreated infections can lead to blindness, particularly those caused by Neisseria gonorrhoeae. Historically, silver nitrate was used for prophylaxis but was found to cause chemical conjunctivitis. Currently, erythromycin, a macrolide antibiotic, is used as an ophthalmic ointment applied within the first hour of life. It works by inhibiting bacterial protein synthesis, preventing bacterial growth and replication. Side effects are rare and include mild eye irritation and redness. Before administration, informed consent must be obtained, and parents should be reassured about the safety and standard nature of the procedure. Proper technique involves cleaning the eyes, applying the ointment, and monitoring for any adverse reactions.
Key Points:
- Erythromycin ointment is used within the first hour of life to prevent neonatal eye infections.
- Infections can lead to blindness if untreated, especially those caused by Neisseria gonorrhoeae.
- Silver nitrate was previously used but caused chemical conjunctivitis.
- Informed consent is necessary before administration, and parents should be educated about the procedure.
- Proper application technique and monitoring for side effects are crucial.
Details:
1. 🦠 Introduction to Neonatal Eye Prophylaxis
- Neonatal eye prophylaxis involves the use of medication to prevent ophthalmia neonatorum, an eye infection commonly caused by Neisseria gonorrhoeae or Chlamydia trachomatis.
- Silver nitrate, erythromycin, or tetracycline ointments are typically used as prophylactic treatments.
- Effectiveness varies, but these treatments significantly reduce the incidence of infection in newborns.
- Potential side effects include transient eye irritation, which is generally considered manageable.

3. 💉 Evolution of Prophylaxis Methods
- Neonatal eye prophylaxis primarily aims to prevent gonococcal ophthalmia neonatorum.
- Historically, silver nitrate was used for neonatal eye prophylaxis.
- Silver nitrate was later found to cause damage to the conjunctiva, resulting in chemical conjunctivitis.
- Modern prophylaxis methods have replaced silver nitrate with antibiotics like erythromycin, which are more effective and have fewer side effects.
- The transition from silver nitrate to antibiotics was driven by the need to reduce chemical damage and increase efficacy.
4. 🧬 Mechanism of Erythromycin
- Erythromycin is the primary medication used in neonatal eye prophylaxis for Neisseria gonorrhoeae, administered as an ophthalmic ointment within the first hour of life.
- It acts by entering the bacterial cell and binding to the 50S subunit of bacterial ribosomes, inhibiting protein synthesis and stopping bacterial growth.
5. 🍼 Administration and Parental Guidance
- Ophthalmic administration is rarely associated with side effects, mainly mild eye irritation and redness.
- Administration of ophthalmic medication should occur within 1 hour after birth to prioritize bonding and breastfeeding.
- Ensure informed consent is obtained from the baby's parents or guardians before administering the medication.
- Reassure parents or guardians that the medication is a standard of care for all newborns.
- Explain the process and importance of obtaining informed consent, emphasizing transparency and understanding.
- Provide clear information on potential side effects and their rarity to alleviate parental concerns.
- Highlight the benefits of timely administration in preventing neonatal infections.
6. 👁️ Application Process and Aftercare
- The application of athic arthy for newborns is not painful, with side effects limited to mild redness and irritation.
- Newborns' eyes may appear red, swollen, or cloudy post-application; do not wipe away the ointment to ensure proper absorption.
- Before administration, assess the baby's eyes for redness, edema, or drainage, and clean each eye with sterile cotton or gauze, wiping from inner to outer canthus.
- For significant drainage or crusting, obtain a specimen and cleanse with sterile saline, followed by sending the specimen for lab culture.
- Apply a 1 cm ribbon of ointment along the lower lid margin of each eye, avoiding contact with the applicator tip and any surfaces.
- For premature babies with fused eyes, apply ointment along the fusion line.
- After administration, gently close the eyes for 30-60 seconds and wipe excess ointment from the periorbital skin, avoiding flushing or wiping from the eyes.
7. 🔍 Summary and Key Takeaways
- Neonatal eye prophylaxis is crucial for preventing ophthalmia neonatorum, a serious eye infection that can lead to blindness if not treated promptly.
- The primary cause of this infection is Neisseria gonorrhoeae, which may be transmitted to the newborn during delivery.
- To combat this, all newborns are administered ophthalmic erythromycin within 1 hour post-birth, which acts by inhibiting bacterial protein synthesis.
- While erythromycin is generally safe, rare side effects such as eye irritation, redness, or hypersensitivity might occur.
- Nursing staff must obtain informed consent, educate parents or guardians about the procedure, ensure proper administration technique, and conduct ongoing monitoring and care to ensure efficacy and address any side effects.
