Abstract

Background: Precise fluid therapy is extremely important during surgeries, as enough circulating blood volume ensures tissue perfusion and cell oxygenation. Yet, extra fluid volume could cause other adverse events, such as heart failure, intestinal swelling, etc. Thus, precise evaluation of the circulating blood volume is essential for maintaining sufficient circulating blood volume and avoiding excessive fluid infusion.

Objective: This study aimed to evaluate the relationship between SVV and circulating blood volume during intraoperative fluid therapy.

Methods: SVV was measured by FloTrac/Vigileo in the study. A prospective cohort study was conducted. 103 patients aged from 20 to 60 years old with an ASA Grade I-II and a diagnosis of meningioma less than 3 centimeters planning for selective neurosurgery were randomly divided into the Crystalloid Group and the Colloid Group. After induction, each Patient received 15 ml/kg of Plasma-Lyte-A or 6% hydroxyethyl starch in 30 min followed by continuous infusion at the speed of 0.1 ml/kg during the next 60 min. Hb concentration, Hct, Delta-BV/kg, and Delta-SVV were recorded every 5 minutes.

Results: The delta-SVV and Delta-bv/kg were significantly higher in the Crystalloid Group than that of the Colloid Group. There was a strong linear correlation between Delta-SVV and Delta-bv/kg in both Crystalloid Group (Delta-bv / kg = 1.108 Delta-SVV + 0.0712, P < .001) and Colloid Group (Delta-bv / kg = 1.047 Delta-SVV + 0.4153, P < .001). An equation between Delta-bv/kg and Delta-SVV was established (Delta-bv / kg = 1.099 Delta-SVV + 0.1139, P < .001).

Conclusion: In conclusion, SVV measured by FloTrac / Vigileo could guile fluid therapy precisely by predicting the blood volume of patients during the intraoperative period, as it has a strong linear correlation with the blood volume of patients who underwent general anesthesia, meaning anesthesiologist could calculate the exact fluid volume for patients' infusion. Further studies with large cohorts and centers would be needed to validate its efficiency.

作为术中循环血容量评估预测因子的 Delta-SVV：一项前瞻性队列研究

背景：精确的液体疗法在手术过程中极为重要，因为足够的循环血量可确保组织灌注和细胞氧合。然而，额外的液体量可能会导致其他不良事件，如心力衰竭、肠道肿胀等。因此，精确评估循环血容量对于维持足够的循环血容量和避免过度输液至关重要：本研究旨在评估术中输液治疗期间 SVV 与循环血容量之间的关系：方法：研究采用 FloTrac/Vigileo 测量 SVV。进行了一项前瞻性队列研究。103 名年龄在 20 至 60 岁之间、ASA 分级为 I-II 级、诊断为小于 3 厘米的脑膜瘤、计划进行选择性神经外科手术的患者被随机分为晶体组和胶体组。诱导后，每位患者在 30 分钟内接受 15 毫升/公斤的血浆-Lyte-A 或 6% 羟乙基淀粉，然后在接下来的 60 分钟内以 0.1 毫升/公斤的速度持续输注。每 5 分钟记录一次 Hb 浓度、Hct、Delta-BV/kg 和 Delta-SVV：结果：晶体液组的 Delta-SVV 和 Delta-bv/kg 明显高于胶体液组。晶体组（Delta-SVV = 1.108 Delta-SVV + 0.0712，P < .001）和胶体组（Delta-bv / kg = 1.047 Delta-SVV + 0.4153，P < .001）的 Delta-SVV 和 Delta-bv/kg 之间均存在较强的线性相关。Delta-bv/kg与Delta-SVV之间建立了等式（Delta-bv/kg = 1.099 Delta-SVV + 0.1139，P < .001）：总之，FloTrac / Vigileo 测量的 SVV 可以预测术中患者的血容量，从而准确指导输液治疗，因为 SVV 与全身麻醉患者的血容量有很强的线性相关性，这意味着麻醉师可以计算出患者输液的准确容量。要验证该方法的有效性，还需要在大型群组和中心开展进一步研究。

期刊介绍： Launched in 1995, Alternative Therapies in Health and Medicine has a mission to promote the art and science of integrative medicine and a responsibility to improve public health. We strive to maintain the highest standards of ethical medical journalism independent of special interests that is timely, accurate, and a pleasure to read. We publish original, peer-reviewed scientific articles that provide health care providers with continuing education to promote health, prevent illness, and treat disease. Alternative Therapies in Health and Medicine was the first journal in this field to be indexed in the National Library of Medicine. In 2006, 2007, and 2008, ATHM had the highest impact factor ranking of any independently published peer-reviewed CAM journal in the United States—meaning that its research articles were cited more frequently than any other journal’s in the field. Alternative Therapies in Health and Medicine does not endorse any particular system or method but promotes the evaluation and appropriate use of all effective therapeutic approaches. Each issue contains a variety of disciplined inquiry methods, from case reports to original scientific research to systematic reviews. The editors encourage the integration of evidence-based emerging therapies with conventional medical practices by licensed health care providers in a way that promotes a comprehensive approach to health care that is focused on wellness, prevention, and healing. Alternative Therapies in Health and Medicine hopes to inform all licensed health care practitioners about developments in fields other than their own and to foster an ongoing debate about the scientific, clinical, historical, legal, political, and cultural issues that affect all of health care.
