Abstract
Objective To explore the possibility of baseline perfusion index (PI) in prediction of incidence of hypotension after combined spinal-epidural anesthesia for caesarean. Methods Thirty patients of American Society of Anesthesiologists (ASA) grade I and Ⅱ undergoing caesarean under combined spinal-epidural anesthesia were enrolled in this study. SBP and PI were observed and recorded after the patients entered the operation room. Then lumbar puncture was applied. After subarachnoid injection, SBP was monitored at 1 min interval until the operation started. The correlation between baseline PI and the decrease in SBP was analyzed. Receiver operating characteristic (ROC) curve was drawn in order to determine the optimal PI value that could predict hypotension. Results Baseline PI value and the decrease in SBP were positively correlated and the correlation coefficient was 0.652 ( = 0.000). The cut-off PI value of 3.95 identified the patients at a risk of spinal anesthesia-induced hypotension with a sensitivity of 0.810 and a specificity of 0.842, the area of ROC was 0.873. The incidence of hypotension in the patients with PI > 3.95 was higher than those with PI < 3.95 (85% vs 20%, = 0.000). Conclusions Baseline PI value is associated with hypotension and could predict the incidence of hypotension induced by combined spinal-epidural anesthesia for caesarean, so baseline PI value could provide reference for prevention and treatment of preoperative hypotension.关键词
