摘　　要：目的观察灌注变异指数（PVI）和中心静脉压（CVP）持续监测用于脑肿瘤手术患者时的变化，探讨PVI和CVP的相关性。方法42例选择ASA分级为Ⅱ-Ⅲ级择期行脑肿瘤切除术患者，入室后持续监测PVI，局部麻醉下行中心静脉穿刺监测CVP。麻醉方式采用全凭静脉麻醉。记录入室时、手术开始时、手术开始后30min、60min、90min和120min时间点的CVP和PVI。结果PVI和CVP在自主呼吸下（入室时）的相关系数r=0．201，机械通气下的相关系数r=0．237。结论PVI和CVP的相关性差，联合指导容量管理的应用价值可能还需要进一步的评估。Objective To observe the changes of pleth variability index （PVI） and central venous pressure （CVP） in patients undergo- ing resection operation of brain neoplasms,and the correlation of PVI with CVP was investigated. Methods Forty-two patients （ASA Ⅱ-Ⅲ grade） undergoing elective resection operation of brain neoplasms were included in the study. PVI was monitored continously with Masio Radical-7 pulse oximeter after patient entering operative room. CVP was monitored after central venous catheterization placed with regional an- esthesia. Total intravenous anesthesia was chosen. CVP and PVI were recorded at the time of entering operative room, operation began, and 30 minutes,60 minutes,90 minutes, 120 minutes after the beginning of operation. Results The correlation coefficient of PVI with CVP was 0. 201 under spontaneously breathing （ at patient entering operative room before anesthesia） and was 0. 237 under mechanical ventilation. Conclusion Correlation of PVI and CVP is lower. The value of PVI might need further research for guiding volume management.
