Description

The Avanos MICROCUFF Paediatric Endotracheal Tube is a cuffed ETT engineered for neonatal through paediatric airway management and anatomically appropriate cuff placement. It is intended for use by trained clinicians in the operating room, ICU, and emergency settings. The tube features a Magill‑type beveled tip and is supplied without a Murphy eye to enable a more distal cuff position within the trachea.

Design and materials

• MICROCUFF cuff: micro‑thin, strong polyurethane with a short, cylindrical geometry that conforms to variable paediatric airway sizes and shapes.
• High‑volume, low‑pressure sealing design to achieve an effective tracheal seal at minimal cuff pressures.
• Distal cuff placement below the cricoid, avoiding the pressure‑sensitive larynx.
• Placement and verification aids: centimetre depth graduations, a black vocal‑cord placement marker just above the cuff, and four precision bands to facilitate and confirm post‑intubation depth.
• Imaging: continuous radiopaque line for X‑ray visibility.
• Construction durability: cuff/tube assembly designed to withstand very high burst pressures (>800 cm H₂O reported).

Clinical performance and benefits

• Effective low‑pressure tracheal seal to reduce gas leakage around the tube.
• Supports minimal/low‑flow anaesthesia and reliable monitoring of end‑tidal CO₂ and anaesthetic gases.
• Enables consistent minute ventilation during positive‑pressure ventilation.
• Helps reduce aspiration of secretions and blood.
• Accommodates variability in paediatric airway anatomy; may reduce the need to replace oversized tubes and re‑intubate.
• Potential to lessen environmental anaesthetic gas pollution and accidental staff exposure in the operating room.
• Cuff pressure should be monitored throughout use.
