ETT Cuff pressure in the ED

Overview

• Question: How many children who are emergently intubated are exposed to a high pressure in their ETT cuff?

• Study: Prospective Cohort study

• Answer: a little over half

ETT Cuff pressure in the ED

What is known?

• Cuff pressure can’t be accurately estimated

• High ETT cuff pressure is associated with adverse effects

• Cuffed ETT use is common in children

• Cuffed ETT use is recommended in children

ETT Cuff pressure in the ED

The question:

• How many children are exposed to a high ETT cuff pressure after emergency intubation?

• Do any factors correlate with a high ETT cuff pressure?

Secondary Outcomes

What was investigated: • Person performing intubation • Person performing cuff inflation • Endotracheal tube size • Patient age • Patient gender • Patient weight• Diagnostic category (medical or trauma)• Month & time of day

Page 11: Endotracheal Tube Cuff Pressure in the Pediatric Emergency Department · 2015. 11. 29. · Endotracheal Tube Cuff Pressure in the Pediatric Emergency Department Edward Ferenczy, MD

Secondary Outcomes

What we found to be statistically significant: • Person performing intubation • Person performing cuff inflation • Endotracheal tube size • Patient age • Patient gender • Patient weight• Diagnostic category (medical or trauma)• Month & time of day

ETT Cuff Pressure in the ED

What was learned:

• Emergently intubated children are likely to be exposed to high ETT cuff pressure

• Regular use of a manometer in the ED may help limit exposure to excessive ETT cuff pressure
