Why the study?

Does heart rate variability analysis quantify the sympatho-vagal balance and stress response during asleep-awake craniotomy?

Structured PICO

Does heart rate variability analysis quantify the sympatho-vagal balance and stress response during asleep-awake craniotomy?

Population

21 patients admitted for tumor resection with language testing, age range 22 to 53 years.

Intervention

Heart rate variability (HRV) analysis during asleep-awake craniotomy (propofol/remifentanil anesthesia, awakened for language testing).

Comparator

Preanesthesia baseline (T1).

Outcome

Heart rate variability (HRV) parameters including LF/HF ratio, heart rate, and systolic arterial blood pressure across 5 intraoperative time points.surrogate

HRV analysis confirms a moderate intraoperative stress response during the awake phases of craniotomy, which may help tailor anesthesia protocols.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

HRV may signal stress during awake craniotomy phases; leaves open its utility for tailoring anesthesia pending prospective validation.
