Abstract:
Objective Onto investigate the significance of the pleth variability index (PVI) in predicting hypotension after epidural anesthesia for cesarean delivery. Methods Sixity seven pregnant women, with ASAⅠ~Ⅱ, aged 19 ~ 34 years, were enrolled for elective cesarean delivery. SBP, BDP, MAP, HR, PI and PVI were measured at 5 min after the parturients arrived in the operation room. SBP, BDP, MAP and HR were measured every 3 min after epidural anesthesia. According to the change rate of SDP or MAP was higher than 30% or not, the parturients were divided into two groups (the hypotension group and the non-hypotension group). Results No significant differences were found in parturients'age, body height, weight, BMI, gestational weeks, SDP, DBP, MAP and HR before anesthesia between two groups. The PVI in the hypotension group was significantly higher than that in the non-hypotension group (P<0.05). A receiver operator characteristic curve analysis showed the area under curve was 0.888 when PVI was used for boundary value. When PVI over 17.35 was used as the occurrence of hypotension, the sensitivity of PVI was 0.727, and specificity was 0.895. Conclusion PVI can be used to predict the occurrence of hypotension after epidural anesthesia for cesarean delivery.
