A clinical comparative study of Microcuff Paediatric Tracheal tube v/s Uncuffed Endotracheal tubes in Paediatric patients undergoing Abdominal surgeries.

Abstract

Introduction: The use of cuffed versus uncuffed endotracheal tubes in pediatric anesthesia is debated. Microcuff tubes are designed to provide an effective seal with minimal cuff pressure. This study compares the performance and safety of microcuff versus uncuffed tubes in children undergoing abdominal surgeries.

Methods: In a randomized trial, 70 children aged 1-8 years were assigned to receive either a microcuff (Group M, n=35) or an uncuffed (Group U, n=35) endotracheal tube. Primary outcomes included ease of intubation, tidal volume leaks, and post-operative complications. Secondary outcomes included ventilation parameters and cuff pressure monitoring.

Results: Intubation ease was similar between groups. Group M had significantly fewer tube exchanges (0% vs. 11.4%, p=0.114) and throat pack requirements (0% vs. 22.9%, p=0.005). Air leaks were higher in Group U (p=0.01). No significant differences were found in oxygenation, ventilation, or post-operative complications.

Conclusion: Microcuff tubes demonstrated advantages over uncuffed tubes, including fewer air leaks and reduced throat pack usage, without compromising safety or ventilation. Microcuff tubes are a safe and effective alternative for pediatric abdominal surgeries, though further research is needed.
