Objective real-time epidural pressure measurement using the CompuFlo® device, a mono-center observational study

Area of Science:

• Pediatric Anesthesiology
• Medical Device Technology
• Pain Management

Background:

• Epidural anesthesia (EA) is crucial for managing intense postoperative pain.
• Detecting the epidural space in young children is challenging due to difficulties in perceiving loss of resistance (LOR).
• The CompuFlo® device offers real-time pressure monitoring during needle insertion.

Purpose of the Study:

• To describe epidural pressure levels during anesthesia in children.
• To investigate the relationship between patient weight and epidural pressure.
• To test the hypothesis that smaller children exhibit lower epidural pressures.

Main Methods:

• Prospective observational study of pediatric surgical patients requiring EA.
• Real-time pressure measurements using the CompuFlo® device (manual and automatic modes) before LOR.
• Correlation analysis of pressure levels with patient weight and other influencing factors.

Main Results:

• Analyzed pressures from 56 procedures in 47 pediatric patients.
• Median pressure before LOR was 174 mmHg (IQR 120-314).
• A significant correlation (r=0.61) was found between pressure and weight; children under 5 kg had significantly lower pressures (p=0.02).

Conclusions:

• The CompuFlo® device effectively measured epidural pressures prior to LOR in children.
• Lower pressure levels in younger/smaller children may contribute to difficulties in epidural space identification.
• These findings provide a basis for future research into pediatric epidural anesthesia techniques.
