Continuing to challenge practice to be evidence based.

Area of Science:

• Critical care nursing
• Evidence-based practice

Background:

• Clinical practice often relies on established habits rather than current evidence.
• Critical care nurses are encouraged to re-evaluate interventions based on research findings.

Purpose of the Study:

• To challenge critical care nurses to examine evidence guiding nursing practice interventions.
• To review four common critical care interventions and compare them with current evidence.

Main Methods:

• Review of literature and evidence for four common critical care interventions.
• Analysis of current recommendations for weight-based medication administration, chest tube patency, sedation interruption, and chest physiotherapy.

Main Results:

• Actual patient weight is crucial for accurate medication dosing; estimates are insufficient, especially in obese patients.
• Chest tube stripping and milking are not necessary for maintaining patency and may cause harm.
• Daily interruption of sedation is appropriate for most mechanically ventilated patients.
• Chest physiotherapy is ineffective for pediatric respiratory conditions and post-extubation atelectasis.

Conclusions:

• Critical care nurses must critically evaluate their practices against current evidence.
• Adopting evidence-based interventions is essential for improving patient outcomes and safety in critical care settings.
