ABSTRACT
16
Background: Hypotension is frequently observed after spinal anesthesia for cesarean section
17
and can be detrimental to both mother and baby. We investigated the role of the pleth
18
variability index for predicting hypotension after spinal anesthesia for cesarean section.
19
Methods: Eighty-five parturients undergoing elective cesarean section under spinal
20
anesthesia were enrolled. We recorded pleth variability index and perfusion index before
21
anesthesia, and blood pressure, heart rate and pulse oxygen saturation before and after
22
anesthesia. The association between baseline pleth variability index and perfusion index with
23
hypotension after spinal anesthesia was explored using multivariate analysis.
24
Results: Hypotension occurred in 42 parturients. Baseline pleth variability index was higher
25
in parturients who experienced hypotension than in those who did not (P
