背景：液体复苏是对抗急性失血性休克的关键，需要及时和准确的血管内容量估计，以获得最佳液体管理。本研究旨在评估是否颈内静脉（IJV）的心脏变异，超声检查评估，可以检测到低血容量状态和预测responsibilitytofluid resources.Methods：患者接受自体血回输择期手术谁是前瞻性招募在研究献血中心2014年8月至2015年1月。分别于献血前、献血中、献血结束、补液结束、止血后5个时间点记录下腔静脉的垂直B超图像。心脏变异的IJV面积和周长进行了客观的测量，使用自动提取程序连同血压和heartrate.Results：共筛选了140例患者，并从104例患者的数据被纳入最终分析。在分析的变量中，只有塌陷指数面积和塌陷指数周长可以检测血管内容量损失和对液体管理responsibility.Conclusions：IJV的心脏变异可能是一个可靠的指标，血管内容量损失和对液体管理的反应在失血性休克。
Background:Fluid resuscitation, which is critical to counter acute hemorrhagic shock, requires prompt and accurate intravascular volume estimation for optimal fluid administration. This study aimed to evaluate whether cardiac variation of internal jugular vein (IJV), evaluated by ultrasonography, could detect hypovolemic status and predict response to fluid resuscitation.Methods:Patients undergoing autologous blood transfusion for elective surgery who were prospectively enrolled at the study blood donation center between August 2014 and January 2015. Vertical B-mode ultrasonography movies of IJV were recorded at five timepoints during blood donation: before donation, during donation, end of donation, end of fluid replacement, and after hemostasis. Cardiac variation of the IJV area and circumference were objectively measured using an automated extraction program together with blood pressure and heart rate.Results:A total of 140 patients were screened, and data from 104 patients were included in the final analyses. Among the variables analyzed, only collapse index area and collapse index circumference could detect both intravascular volume loss and response to fluid administration.Conclusions:Cardiac variation of IJV may be a reliable indicator of intravascular volume loss and response to fluid administration in hemorrhagic shock.
