研究目的: |
及时有效的液体复苏是治疗脓毒症低灌注的基础和首要方法。脓毒症液体治疗中使用的液体分为晶体液和胶体液:晶体液易导致组织水肿,加重微循环障碍;胶体液通过胶体渗透压维持血管内水分,改善微循环灌注。 临床上常见的胶体包括白蛋白、羟乙基淀粉和明胶。白蛋白从人类血液中提取,来源稀少且价格昂贵,指南建议在大量液体复苏时使用。羟乙基淀粉由土豆或玉米淀粉制成,但大量研究表明在脓毒症患者中会引起肾功能损伤及死亡率增加因而不推荐使用。明胶是当前唯一可用于脓毒症患者低血容量治疗的人工胶体液,但缺乏高质量证据支持。 为探索胶体液在脓毒症治疗中的潜在价值,本研究聚焦于平衡明胶溶液(4%明胶+平衡晶体液)并提出以下科学假设:平衡明胶溶液通过其特有的胶体渗透压效应,能够更有效地改善液体平衡,维持血流动力学稳定,进而优化微循环灌注,最终可能促进器官功能恢复并改善临床预后。 |

Objectives of Study: |
Timely and effective fluid resuscitation remains the cornerstone treatment for sepsis-induced hypoperfusion. The fluids used in sepsis management are classified as crystalloids and colloids. Crystalloids tend to cause tissue edema and worsen microcirculatory dysfunction, while colloids maintain intravascular volume through colloid osmotic pressure to improve microcirculatory perfusion. The commonly used clinical colloids include albumin, hydroxyethyl starch, and gelatin. Albumin is extracted from human blood and is limited by scarcity and high cost, with guidelines recommending its use mainly for large-volume resuscitation. Hydroxyethyl starch is derived from plant starch but has been shown in multiple studies to increase renal injury and mortality in septic patients, making it unsuitable for clinical use. Gelatin currently stands as the only artificial colloid solution approved for treating hypovolemia in sepsis patients, though supporting evidence from high-quality studies remains insufficient. To investigate the potential benefits of colloids in sepsis treatment, this study focuses on balanced gelatin solution containing 4% gelatin combined with balanced crystalloids. We propose that this solution may more effectively improve fluid balance through its unique colloid osmotic effects, maintain hemodynamic stability, optimize microcirculatory perfusion, and ultimately lead to better organ function recovery and improved clinical outcomes compared to existing alternatives. |
