About Us
The intranasal mucosal atomization procedure begins with preparation of both patient and equipment. First, explain the steps to the patient and obtain consent. Position the patient seated or supine with the head tilted back at approximately 20–30 degrees to straighten the nasal passages. Assemble the device by attaching the atomizer tip firmly onto a 1 mL or 3 mL luer‑lock syringe, then draw up the prescribed medication volume, ensuring no air bubbles remain. Check the total volume per nostril does not exceed 1.0–1.5 mL to prevent runoff.
Next, don appropriate personal protective equipment and perform hand hygiene. Apply a preservative‑free nasal decongestant or topical anesthetic spray if indicated, waiting 2–3 minutes for absorption. Instruct the patient to breathe normally through their mouth. Gently insert the atomizer tip just past the nasal vestibule, directing it toward the mid‑inferior turbinate at a 45‑degree angle relative to the face. Ensure the nozzle is neither too deep (to avoid contact with turbinates) nor too shallow (to prevent spray escaping).
Depress the syringe plunger steadily and continuously, delivering the medication in a fine mist. Pause for a few seconds, then repeat in the opposite nostril if required. Encourage the patient to refrain from sniffing or swallowing during the spray to maximize mucosal deposition. After administration, have the patient remain still with head tilted for another 1–2 minutes to allow absorption and minimize dripping.
Finally, dispose of the MAD device in a sharps or biohazard container as per institutional policy. Document the medication name, dose, time, patient response, and any adverse events. Provide patient instructions to avoid blowing their nose or sneezing forcefully for at least 10 minutes. Evaluate efficacy within 5–15 minutes and prepare for repeat dosing if clinically indicated.
| Step | Action | Key Point |
|---|---|---|
| Preparation | Explain procedure; assemble syringe and atomizer | Max 1.5 mL per nostril; remove air bubbles |
| Patient Positioning | Seat or supine; head tilted 20–30° backward | Straightens nasal passages |
| Pre‑treatment | Apply decongestant/anesthetic spray (if needed) | Wait 2–3 min before atomization |
| Insertion | Insert tip past vestibule at 45° toward inferior turbinate | Avoid deep contact; ensure seal |
| Delivery | Depress plunger steadily; spray mist | No sniffing or swallowing during spray |
| Post‑administration | Maintain head position 1–2 min; dispose device safely | Prevents runoff; ensures proper absorption |
| Documentation & Follow‑up | Record dose/time/response; monitor within 5–15 min | Note adverse events; plan repeat dose if needed |
This standardized procedure optimizes drug delivery, enhances patient comfort, and minimizes waste or adverse events.
