摘要:

目前以腹腔镜技术为代表的微创手术在普外科应用广泛,然而气腹带来的病理生理变化给患者容量反应性的评估带来挑战,虽然近年来每搏量变异度(stroke volume variation, SVV)在容量治疗中备受关注,但SVV评估容量反应性的准确性在腹腔镜手术中存在争议。文章拟围绕SVV在气腹下能否准确评估容量反应性及SVV在普外科腹腔镜手术中指导液体治疗的最新研究进展进行综述。研究发现气腹后SVV评估容量反应性的阈值增大并且SVV在一定范围气腹压内才能准确评估容量反应性。除此之外,体位、通气模式及测量工具可有限影响SVV准确性。既往实验研究表明 ,SVV在腹腔镜肝、泌尿、胃肠等手术中指导容量治疗均使患者获益。因此,SVV评估患者气腹状态时容量反应性具有可行性,但是未来需要更加优化的测量方法和测量工具进一步提高SVV在气腹下的准确性和实用性。

Abstract:

Laparoscopic technique, as represented by minimally invasive surgery, has been widely applied in general surgical departments. However, physiological changes caused by pneumoperitoneum often bring about challenges to the assessment of fluid responsiveness. Although stroke volume variation (SVV) has been drawn increasing attentions in fluid therapy, it is still controversial that whether SVV can accurately predict fluid responsiveness in these surgeries. This article was to review the accuracy of SVV to estimate fluid responsiveness in pneumoperitoneum condition and the latest research progress in SVV directing fluid therapy during different surgeries. We found the value of SVV as a predictor of fluid responsiveness increases after pneumoperitoneum, and SVV can accurately evaluate fluid responsiveness under a range of intra-abdominal pressure. In addition, position, ventilation mode and measurement tools could affect the accuracy of SVV to a limit degree. Previous studies showed that SVV is beneficial for patients on guiding fluid therapy in laparoscopic hepatectomy, urinary surgery, and gastrointestinal surgery. In conclusion, SVV has feasibility in predicting fluid responsiveness in pneumoperitoneum patients, but more optimized methods and accurate measurement tools are needed to improve the accuracy and utility of SVV in the future.
