Implication

Pre-anaesthetic heart rate may stratify hypotension risk; hypothesis-generating and should not yet alter practice.

Structured PICO

Do pre-anaesthetic non-invasive haemodynamic parameters predict hypotension in parturients undergoing caesarean section with spinal anaesthesia?

P
Population
81 parturients undergoing caesarean section with spinal anaesthesia
I
Intervention
Measurement of pre-anaesthetic non-invasive haemodynamic parameters (pulse oximetry perfusion index, pleth variability index, heart rate, ratio of low-frequency to high-frequency components of heart rate variability, and entropy of heart rate variability)
O
Outcome
Hypotension during caesarean sectionsafety

Pre-anaesthetic heart rate is an independent predictor of hypotension during caesarean section under spinal anaesthesia, whereas pulse oximetry and heart rate variability parameters are not.
