Cuffed versus uncuffed endotracheal tubes in children: a meta-analysis

Area of Science:

• Pediatric Anesthesiology
• Critical Care Medicine
• Respiratory Therapy

Background:

• Cuffed endotracheal tubes (ETTs) are increasingly used in pediatric patients.
• The safety and efficacy of cuffed ETTs in small children remain a subject of debate.

Purpose of the Study:

• To evaluate the evidence on postextubation morbidity and tracheal tube (TT) exchange rates associated with cuffed ETTs versus uncuffed ETTs in children.
• To compare the incidence of postextubation stridor and TT exchange rates between cuffed and uncuffed ETTs.

Main Methods:

• A systematic literature search was performed across major databases (PubMed, Web of Science, Embase, Cochrane).
• Included studies were randomized controlled trials (RCTs) and prospective cohort studies comparing cuffed and uncuffed ETTs in children.
• Data were pooled using random effects meta-analysis to assess primary and secondary outcomes.

Main Results:

• Analysis of 4 studies (3782 patients) showed no significant increase in postextubation stridor with cuffed ETTs (RR=0.88; p=0.36).
• Cuffed ETTs significantly reduced the tracheal tube exchange rate (RR=0.07; p<0.00001).
• No significant differences were observed in the need for re-intubation or duration of tracheal intubation.

Conclusions:

• Cuffed endotracheal tubes are effective in reducing tracheal tube exchanges in children.
• The use of cuffed ETTs does not elevate the risk of postextubation stridor compared to uncuffed ETTs.
• Findings support the use of cuffed ETTs in pediatric airway management.
