Key result
Performing critical ICU procedures linked to significant physiologic stress and a ~50% drop in trainee RMSSD.
Why the study?
Data on physiologic stress measured by heart rate variability in pediatric critical care trainees performing real-time procedures were limited.
Does performing high-stakes ICU procedures increase physiologic stress measured by HRV in pediatric critical care trainees compared to baseline?
Comparison
During high-stakes ICU procedures vs baseline

May warrant stress mitigation training for pediatric critical care trainees; leaves open whether interventions improve procedural outcomes.
Does performing high-stakes ICU procedures increase physiologic stress measured by HRV in pediatric critical care trainees compared to baseline?
Pediatric ICU trainees experience significant increases in physiologic stress, as measured by heart rate variability, when performing emergent procedures.
Engelbrecht et al. (2026) studied this question. Pediatric ICU trainees performing critical procedures demonstrated significant physiologic stress, marked by decreased RMSSD (34.53 vs 17.28) and SDNN (47.12 vs 34.22) from baseline.
