Description

Overview

Avanos MICROCUFF Paediatric Endotracheal Tubes are cuffed airway devices for neonatal and pediatric patients. They use an ultra‑thin, high‑volume, low‑pressure (HVLP) polyurethane MICROCUFF designed to achieve an effective tracheal seal at minimal cuff pressure, aiming to minimize mucosal injury and reduce aspiration risk. The cuff’s cylindrical profile is positioned near the distal tip to seal at the subglottic level. Tubes are supplied without a Murphy eye.

Key features and design

• HVLP, micro‑thin polyurethane cuff engineered for a reliable seal at low cuff pressures.
• Small cylindrical cuff located near the distal tip to support subglottic sealing.
• Positioning aids for accuracy: black vocal cord placement marker and four verification bands to help confirm insertion depth.
• Centimeter depth markings to support documentation and re‑checks over time.
• Continuous radiopaque line to enable X‑ray visibility and confirmation of tube position.
• Supplied without a Murphy eye.

Sizes and configurations (internal diameter, mm)

• Oral/Nasal Magill: 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0
• Oral Curved (RAE): 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5

Intended use and settings

For use by trained clinicians managing pediatric airways in operating theatres, intensive care units, and emergency settings.

Clinical performance

In pediatric abdominal surgery (ages 1–8), MICROCUFF tubes maintained an effective tracheal seal with mean cuff pressure approximately 9.06 ± 0.8 mmHg (median 9; range 8–11 mmHg). No tube exchanges were required in the observed cohort, and throat packs were not used. Oxygenation and ventilation parameters (SpO2, EtCO2, inspiratory/expiratory volumes, and peak airway pressures) were comparable to standard expectations. Early and late postoperative complications up to 24 hours were not increased in the MICROCUFF group.

Key takeaways

• Effective tracheal sealing at low cuff pressures for pediatric patients.
• Near‑tip cylindrical cuff and clear depth markers support accurate placement and ongoing verification.
• Clinical data demonstrate low cuff pressures with maintained ventilation and no added complications in the reported cohort.
