Overview

Preoperative heart rate variability analysis, specifically a high LF/HF ratio, can identify patients at risk for severe hypotension following subarachnoid block for elective cesarean delivery.

Structured PICO

Does preoperative heart rate variability predict severe hypotension after subarachnoid block in patients undergoing elective cesarean delivery?

P
Population
60 patients (41 retrospective, 19 prospective) scheduled to undergo elective cesarean delivery during subarachnoid block (SAB)
I
Intervention
Preoperative heart rate variability (HRV) analysis (relative low frequency [LF], relative high frequency [HF], and LF/HF ratio)
O
Outcome
Decrease in systolic blood pressure (SBP) after SAB, classified as mild (SBP > 100 mmHg), moderate (100 > SBP > 80 mmHg), or severe (SBP < 80 mmHg)surrogate

Preoperative heart rate variability analysis, specifically a high LF/HF ratio, can identify patients at risk for severe hypotension following subarachnoid block for elective cesarean delivery.
