LF/HF-guided prophylaxis may avert hypotension in high-risk cesarean delivery under spinal block; extends heart rate variability risk stratification to randomized evidence.
Does LF/HF-guided prophylactic treatment with vasopressors or colloids prevent severe hypotension in women undergoing elective cesarean delivery during subarachnoid block?
Heart rate variability (LF/HF ratio) can identify patients at high risk for hypotension after subarachnoid block, and targeted prophylactic vasopressor or colloid therapy effectively prevents severe hypotension.
