Quality of sedation during mechanical ventilation

Area of Science:

• Pediatric Intensive Care
• Anesthesiology
• Pharmacology

Background:

• Effective sedation is crucial for ventilated patients in the pediatric intensive care unit (PICU).
• Assessing sedation quality, especially in patients receiving neuromuscular blocking agents, presents unique challenges.

Purpose of the Study:

• To evaluate the quality of sedation in mechanically ventilated children within a general PICU setting.
• To assess sedation effectiveness in patients receiving neuromuscular blocking agents.

Main Methods:

• Utilized an arousability scale based on response to tracheal suction to determine sedation levels in 28 ventilated children.
• Compared observed sedation levels against a predetermined desired sedation target.
• Conducted 81 assessments, including 32 in 15 children after temporary discontinuation of neuromuscular blocking agents.

Main Results:

• Overall, 90% of the 81 sedation assessments were deemed satisfactory.
• In patients temporarily off neuromuscular blocking agents, 97% of 32 assessments met satisfactory sedation levels.
• Continuous intravenous midazolam and morphine, supplemented with oral chloral hydrate and antihistamines, achieved good sedation.

Conclusions:

• A continuous intravenous midazolam and morphine regimen, with supplementary oral agents, provides satisfactory sedation for most ventilated PICU patients.
• This sedation strategy is effective even in pediatric patients requiring neuromuscular blocking agents.
• The study supports the use of this multimodal sedation approach for improving patient comfort and care in the PICU.
