Description

The Avanos MICROCUFF Paediatric Endotracheal Tube is a cuffed airway device designed for neonatal and pediatric patients, providing a reliable tracheal seal at ultra‑low cuff pressures. Its micro‑thin polyurethane cuff and optimized geometry are intended to seal within the trachea while maintaining a cuff‑free subglottic zone. The tube is supplied sterile and natural rubber latex‑free for use by trained clinicians in operating rooms, intensive care units, and emergency settings.

Key features and design

• Micro‑thin (~10 microns) polyurethane cuff with true high‑volume, low‑pressure characteristics
• Short, cylindrical cuff positioned near the tube tip to seal in the trachea, away from the pressure‑sensitive larynx
• Effective sealing typically achieved at approximately 11 cm H2O; cuff membrane burst pressure >800 cm H2O
• Supplied without a Murphy eye
• Continuous radiopaque line for X‑ray visibility
• Centimeter depth markings and black vocal cord placement marker
• Four precision verification bands to help confirm depth after intubation
• Sterile; Natural Rubber Latex‑free
• Blue ventilator connector

Intended use and settings

For oral or nasal endotracheal intubation of neonatal and pediatric patients by clinicians experienced in pediatric airway management. Suitable for operating rooms, ICUs, and emergency care where controlled ventilation and reliable gas monitoring are required.

Sizes and configurations

• Oral/Nasal Magill (oral or nasal route): inner diameters (mm) 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0
• Oral Curved (RAE) (oral route): inner diameters (mm) 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5

Clinical and operational benefits

• Sealed airway helps minimize leak and supports positive‑pressure ventilation with consistent minute ventilation
• Enables reliable monitoring of end‑tidal CO2 and anesthetic gases/oxygen consumption; supports minimal/low‑flow anesthesia techniques
• Ultra‑low sealing pressures aim to reduce risk of mucosal and airway trauma
• Cuff design accommodates variations in pediatric airway size and shape, potentially reducing tube exchanges due to fit
• Effective seal helps reduce aspiration risk of blood and secretions

Representative clinical data

• In a 500‑patient pediatric study, 1.6% required re‑intubation due to incorrect size selection, and 0.4% experienced post‑extubation croup requiring short‑term therapy
• In children aged 2–4 years using a 4.0 mm ID tube, the median cuff pressure to achieve a seal was about 11 cm H2O within 5 minutes after intubation (assessed by auscultation)
