Flawless Drug Administration in Ear, Eye, Nasal, Bladder & Rectal

Introduction to Flawless Drug Administration

Administering drugs perfectly into the ear, eye, nasal cavity, bladder, or rectal route is a skillful art known as instillation in nursing science. Precision, compassion, and knowledge make the process both effective and safe, boosting patient comfort and outcomes. For Indian nurses and students, excelling in these clinical skills is foundational for best-in-class patient care.

Focus Word: Instillation

Throughout these notes, the term instillation takes center stage. It embodies the act of carefully introducing a drug dropwise or in small amounts into a body cavity or space.

Core Principles of Flawless Instillation

1. Ear Medication Administration (Otic Route)

Key Objectives:

• Deliver medication precisely to the external auditory canal.
• Alleviate infection, inflammation, pain, or facilitate wax removal through flawless instillation.

Step-by-Step Instillation Process

1. Verify medication order and gather all supplies. Check patient identity.
2. Explain the procedure to promote patient cooperation.
3. Ensure hands are washed; wear clean non-sterile gloves[1][5].
4. Position patient: adult – on side with affected ear upward; child – preferably lying down.
5. Warm otic solution (never cold) to prevent vertigo (body temp preferred)[5].
6. Clean the external pinna with moistened, lint-free gauze if required (do not insert cotton swabs into the ear canal).
7. Pull pinna:
   Adults: Up and back
   Children <3 years: Down and back
8. Hold dropper 0.5–1 cm above canal; do not touch canal walls.
9. Instill prescribed number of drops gently on the canal wall, not directly onto eardrum.
10. Ask patient to lie still for 5 minutes to allow absorption; apply gentle pressure to tragus.
11. If ordered, place a loose sterile cotton ball at the entrance to the canal.
12. Dispose gloves, provide comfort, and record procedure in nurse record.

Key Points:

• Instillation at room temperature is essential for patient comfort.
• Never insert instruments into the auditory canal.
• Observe for pain, discharge, or dizziness post procedure[5].

2. Eye Drops Application (Ophthalmic Route)

Key Objectives:

• Treat local eye conditions, infections, dryness, allergies, or facilitate examination by effective instillation.

Step-by-Step Instillation Process

1. Check label thrice: during retrieval, preparation, and before administration at bedside[1][5].
2. Perform hand hygiene and wear gloves.
3. Explain the procedure; offer a tissue.[1]
4. Ask patient to tilt head back (supine or seated supported by pillow).
5. Clean eye from inner to outer canthus, if needed.
6. With dominant hand, hold dropper 1 cm above conjunctival sac; non-dominant hand gently pulls down lower eyelid to create a pocket.
7. Instill correct number of drops into lower conjunctival sac (never directly on cornea)[5].
8. Ask patient to close eyes gently (do not squeeze) and move eyeball to spread medication.
9. For drops: apply gentle pressure to inner canthus (nasolacrimal duct) for 30–60 seconds to prevent systemic absorption.[1]
10. Do not allow the patient to rub the eyes[1][5].
11. Dispose gloves, document medication name, dose, eye(s) treated, and patient’s response.

Key Points:

• Separate dropper for each patient/eye if possible.
• Wait 5 minutes between different eye medications.
• Monitor for blurred vision, stinging, or allergic reaction[5].

3. Nasal Drug Administration (Nasal Route)

Key Objectives:

• Deliver decongestants, steroids, antihistamines, or vaccines through nasal instillation.
• Treat systemically or locally via the highly vascular mucosa.

Step-by-Step Instillation Process

1. Get patient’s consent; explain action, effects/side effects.
2. Perform hand hygiene, don gloves[1][5].
3. Ask patient to blow nose gently.
4. Position:
   – Lying: supine, head tilted backward with a pillow below shoulders.
   – Sitting: patient tilts back head or turns to side for maxillary sinus targeting.
5. Nasal drops: Hold dropper 1 cm above nostril opening; avoid contact.
6. Instill drops as per order, ask patient to breathe through mouth.[1]
7. Nasal sprays: Instruct to occlude opposite nostril, inhale gently while spraying.[1]
8. Remain with head tilted for 2–3 minutes.
9. Wipe excess, offer tissue, remove gloves and repeat hand hygiene.
10. Document medication, nostril(s), and response.

Key Points:

• Instillation should avoid touching nasal mucosa.
• Do not forcefully blow nose afterwards.
• Monitor for irritation, bleeding, or headaches.[1][5]

4. Bladder Drug Instillation (Urological Route)

Key Objectives:

• Treat or prevent infection, provide local anesthesia, or aid urinary tract healing via direct instillation into the bladder.[4]

Step-by-Step Instillation Process

1. Verify prescription, gain patient’s consent, explain need and process.
2. Perform hand hygiene, arrange a sterile field.
3. Position patient supine with knees flexed and apart.
4. Use sterile gloves and equipment; insert a lubricated sterile urinary catheter under aseptic technique.
5. Aspirate residual urine and clamp catheter if ordered.
6. Instill medication solution gently via catheter using a sterile syringe.
7. Retain drug in bladder (“dwell time”) as per order, usually 15-30 minutes.
8. Afterward, unclamp and drain bladder as needed.
9. Provide perineal hygiene, remove gloves, ensure comfort, and record procedure, drug, volume, and dwell time.

Key Points:

• Strict aseptic technique is vital for instillation.
• Do not exceed recommended instillation volume.
• Monitor for burning, urgency, pain, or infection post-procedure.

5. Rectal Drug Delivery (Proctological Route)

Key Objectives:

• Provide local or systemic drug effects for patients unable to take oral medications via rectal instillation or insertion.[4][11]

Step-by-Step Instillation Process

1. Confirm indication and obtain consent; explain the manner and reasons for rectal route.
2. Gather equipment—gloves, lubricant, medication (suppository, enema, foam, or gel).
3. Wash hands, don gloves.[11]
4. Position patient in left lateral (Sims’) position with right knee flexed for comfort.[11]
5. Apply lubricant to medication and index finger.
6. Separate buttocks, instruct patient to relax by breathing slowly.
7. Insert medication rounded end first along rectal wall, past internal sphincter (~5cm in adults).
8. Ask patient to remain in same position for at least 5–10 minutes to ensure complete absorption.[11]
9. Remove gloves, perform hand hygiene, provide comfort, and ensure privacy.
10. Document drug type, dose, time, and patient response.

Key Points:

• Instillation by rectal route is faster, has higher bioavailability than oral in many cases ([11]).
• Contraindicated in rectal bleeding, surgery, or low platelets.[11]
• Monitor for dizziness, vasovagal reaction, or discomfort post-administration.

  A: Aseptic non-touch technique to avoid infection and confirming medication identity before administration.[1][5]
• Q: Why use different positions for different routes?
  A: Each route (ear, eye, nasal, bladder, rectal) has specific anatomy. Proper position ensures optimal distribution and effect[1][5][11].
• Q: What should be done if a patient reports burning or pain post-instillation?
  A: Stop, assess site, inform doctor, and document response. Never ignore post-instillation complaints.
