Home Usability of a Nasal Lavage System in Children

Nasal congestion is an important complication of viral upper respiratory infections in young children. It can lead to poor eating, sleeping and breathing. Recently, the FDA recommended against using over-the-counter cold remedies in young children because of inefficacy and occasional dangerous side effects. A commonly recommended non-drug solution for nasal congestion is nasal suctioning. This can be effective but currently available methods have been found to be awkward, uncomfortable and ineffective.

The studied device has potential for making nasal suctioning easy to perform in the home setting, especially in young children. It is already FDA cleared for professional use and this study was developed to demonstrate that it is appropriate for the home as well. This would be significant as it would allow parents a strategy of clearing their child's nose without drugs.

The device is automatic and handheld that can irrigate and/or aspirate the nasal cavity with hospital-grade suction. The handle houses a pump that can achieve air flows known to be effective for infant nasal suctioning in the hospital. A disposable wash-head is placed on top. It has an irrigation chamber with 0.9% saline and another chamber for collecting the aspirated nasal contents. The unit operates from a single bi-functional button.

Several key safety features have been built in such as: a tip that is shaped to maximize the seal but prevent intrusion into the nose; an irrigation function that delivers an optimal volume but prevents flooding the nasal cavity; and a pump that can deliver suction known to be effective in the hospital but whose safety valve does not allow it to rise above dangerous levels.

Participants were parents of children who have nasal congestion for whom nasal suctioning is traditionally recommended. They were asked to review the instruction manual of the device, and then use it on their children.
