Pain assessment during blood collection from sedated and mechanically ventilated children

Area of Science:

• Pediatric Intensive Care
• Pain Management
• Critical Care Medicine

Background:

• Sedated and mechanically ventilated children in pediatric intensive care units (PICUs) require careful pain assessment.
• Routine procedures can cause pain, potentially impacting physiological stability.

Purpose of the Study:

• To assess pain and observe physiological parameters in sedated, mechanically ventilated children during a routine arterial blood gas collection.
• To evaluate the effectiveness of the Face, Legs, Activity, Cry and Consolability (FLACC) scale and physiological monitoring in this population.

Main Methods:

• An observational study was conducted in a PICU involving 35 children (1 month-12 years).
• Pain was assessed using the FLACC scale before, during, and after arterial blood gas collection.
• Physiological parameters including heart rate, respiratory rate, oxygen saturation, and blood pressure were recorded.
• Sedation levels were verified using the COMFORT-B scale.

Main Results:

• A statistically significant increase in FLACC scores (p = 0.0001) was observed during the painful procedure.
• Significant increases in heart rate (p = 0.03), respiratory rate (p = 0.001), and diastolic blood pressure (p = 0.006) were noted due to pain.
• These physiological changes indicate a pain response in sedated pediatric patients.

Conclusions:

• Standardized pain assessment using the FLACC scale is effective in identifying procedural pain in critically ill children.
• Monitoring physiological parameters alongside pain scores provides a comprehensive approach to pain evaluation.
• Consistent execution of pain and physiological assessments is recommended for optimizing pain management in PICUs.
