What Is 'Normal?' Evaluating Vital Signs.

Area of Science:

• Pediatric Nursing
• Evidence-Based Practice
• Clinical Assessment

Background:

• Routine vital sign (VS) assessments in pediatric patients are common practice.
• Concerns exist regarding the necessity and frequency of VS monitoring in children.
• Limited evidence addresses the optimal frequency of VS assessment in this population.

Purpose of the Study:

• To determine "normal" vital sign parameters in pediatric patients aged 1 to 5 years.
• To establish criteria for significant changes in vital signs for this age group.
• To inform evidence-based guidelines for VS assessment frequency in children.

Main Methods:

• Conducted extensive literature searches, including systematic reviews, case-control, and descriptive studies.
• Reviewed textbooks and articles on pediatric early warning signs (PEWS).
• Synthesized findings from five systematic reviews, one case-control study, five descriptive studies, and eight textbooks.

Main Results:

• Systematic reviews indicate vital signs are poorly defined and unreliable indicators of deterioration in young children.
• Normative VS data is inconsistent and often contradictory.
• Pediatric early warning sign literature shows a lack of consistent change parameters.
• High-quality research on normative VS values and assessment frequency is scarce.

Conclusions:

• There is a significant lack of consistent, high-quality research on normative vital signs and significant change parameters in children.
• Current evidence does not support routine VS assessment frequency.
• Further research is needed to develop evidence-based guidelines for pediatric VS assessment and monitoring.
