体外研究 (In Vitro) |
脑外伤后,高渗乳酸钠溶液可增强认知功能(TBI)。在猪脑外伤模型中,高渗乳酸钠溶液还可降低颅内压 (ICP),并通过小动脉血管舒张增加脑血流量 [2][3]。假单胞菌、乳酸杆菌、肠杆菌科、需氧和嗜冷菌群以及其他偏态人力资源均受到乳酸钠的抑制[6]。

体内研究 (In Vivo) |
设计和背景:一项成人ICU的前瞻性开放随机研究。
患者:34例孤立性严重TBI(格拉斯哥昏迷评分<或= 8)和颅内高压患者被分配接受等量高渗和等容治疗,包括甘露醇或乳酸钠。当ICP无法控制时,应采用与替代治疗交叉的抢救治疗。主要终点是4小时后降低颅内压的有效性,次要终点是成功治疗颅内高压发作的百分比。分析是在意向治疗和实际治疗两种情况下进行的。[2]

动物实验 |
Measurements and results: Compared to mannitol, the effect of the lactate solution on ICP was significantly more pronounced (7 vs. 4 mmHg, P = 0.016), more prolonged (fourth-hour-ICP decrease: -5.9 +/- 1 vs. -3.2 +/- 0.9 mmHg, P = 0.009) and more frequently successful (90.4 vs. 70.4%, P = 0.053).
Conclusion: Acute infusion of a sodium lactate-based hyperosmolar solution is effective in treating intracranial hypertension following traumatic brain injury. This effect is significantly more pronounced than that of an equivalent osmotic load of mannitol. Additionally, in this specific group of patients, long-term outcome was better in terms of GOS in those receiving as compared to mannitol. Larger trials are warranted to confirm our findings.[2]

其他信息 |
Sodium lactate is an organic sodium salt having lactate as the counterion. It has a role as a food preservative and a food acidity regulator. It is an organic sodium salt and a lactate salt. It contains a lactate.
Sodium Lactate is a sodium salt of racemic or inactive lactic acid with alkalinizing and electrolyte replenishing property. Upon metabolism, sodium lactate is converted to bicarbonate, thereby increasing plasma bicarbonate, which facilitates removal of hydrogen ion and lactate from blood stream and leads to raised blood pH. Compound Sodium Lactate Solution is a multiple electrolyte, isotonic, crystalloid solution for intravenous infusion containing sodium chloride, potassium chloride, calcium chloride dihydrate, and sodium lactate, which can restore the electrolyte balance, normalize pH, and provide water for hydration. Upon intravenous administration, the compound sodium lactate solution will replace any lost body fluids and electrolytes thereby providing hydration as well as normalizing electrolyte concentrations. In addition, conversion of sodium lactate to bicarbonate increases plasma bicarbonate levels, which facilitates the removal of hydrogen ions from the blood stream, raises blood pH and normalizes the acid-base balance. The sodium salt of racemic or inactive lactic acid. It is a hygroscopic agent used intravenously as a systemic and urinary alkalizer. See also: Sodium Cation (has active moiety) ... View More ... |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
