    [摘要]?目的?探討高龄肺癌患者超声测量下腔静脉内径的呼吸变异率(respiratory?variability?of?diameter?of?inferior?vena?cava，RIVC)评估容量负荷的价值。方法?选取2019年1月至2022年7月于浙江金华广福肿瘤医院择期行肺癌根治术的高龄患者78例为研究对象。术前30min超声检测RIVC和左室舒张末期容积(left?ventricular?end?diastolic?volume，LVEDV)，根据术中平均动脉压(mean?arterial?pressure，MAP)和中心静脉压(central?venous?pressure，CVP)评估患者的容量负荷。结果?78例患者中正常容量组39例、低容量组31例和高容量组8例。低容量组和高容量组患者的RIVC和LVEDV均显著高于正常容量组(P0.05)。Spearman检验发现，RIVC与术中MAP和CVP均呈显著负相关(P0.05)。78例患者发生术中低血压9例，低血压患者的RIVC显著高于血压正常患者(P[Abstract]?Objective?To?explore?value?of?respiratory?variability?of?diameter?of?inferior?vena?cava?(RIVC)?by?ultrasound?for?elderly?patients?with?lung?cancer?to?evaluate?volume?load.?Methods?A?total?of?78?elderly?patients?who?received?radical?surgery?for?lung?cancer?in?Zhejiang?Jinhua?Guangfu?Tumor?Hospital?from?January?2019?to?July?2022?were?selected?as?subjects.?RIVC?and?left?ventricular?end?diastolic?volume?(LVEDV)?were?measured?by?ultrasound?30?min?before?operation.?According?to?mean?arterial?pressure?(MAP)?and?central?venous?pressure?(CVP)?to?assess?patients?volume?load.?Results?There?were?39?patients?in?normal?volume?group ......
