Abstract

Aims

Previous studies suggest that infusing cold crystalloid fluid may have beneficial hemodynamic effects. This raises questions about the optimal temperature for fluid administration in the management of hypotensive patients, particularly regarding its impact on hemostasis and safety in patients at risk of bleeding. This study examined the effects of administering a 1000 mL bolus of Ringer's lactate at a temperature of 10 °C or 22 °C on hemostasis.

Methods

Twenty-five healthy participants were randomized to receive Ringer's lactate at either 10 °C or 22 °C, followed by cross-over to the alternative temperature. The primary outcome was change in clotting time. Secondary outcomes included alterations in thromboelastometry amplitude after 5 and 10 min, maximum clot firmness and maximum lysis at baseline and after 30 min. Additional secondary outcomes were differences in activated partial thromboplastin time (aPTT), international normalized ratio (INR), platelet count, platelet pre-activation and fibrinogen.

Results

ROTEM® analysis demonstrated a prolonged clotting time (mean difference: 2.6 s, 95 % CI: 0.30 to 4.90) after 30 min among participants who received a 10 °C bolus. No other alterations were observed in thromboelastometry. Additionally, fibrinogen levels were slightly elevated after 30 min.

Conclusion

Administration of a bolus of Ringer's lactate at 10 °C compared to 22 °C resulted in a minor prolongation of clotting time after 30 min as assessed by thromboelastometry and had minimal impact on hemostasis. Fibrinogen was slightly elevated after 30 min. We conclude that administering 1000 mL of cold fluids does not notably affect hemostasis and is considered safe in healthy adults.
在健康成人中,与22℃冷液丸相比,10℃冷液丸不影响止血——一项随机交叉试验
目的以往的研究表明,注入冷晶体液可能对血流动力学有有益的影响。这就提出了低血压患者输液的最佳温度,特别是对有出血风险患者的止血和安全性的影响的问题。本研究考察了在10°C或22°C温度下给予1000ml乳酸林格氏酸丸对止血的影响。方法25名健康受试者随机接受10°C或22°C的乳酸林格氏液治疗,然后切换到替代温度。主要观察指标为凝血时间的改变。次要结果包括5分钟和10分钟后血栓弹性测量振幅的变化,基线和30分钟后最大凝块硬度和最大溶解。其他次要结果包括活化的部分凝血活素时间(aPTT)、国际标准化比率(INR)、血小板计数、血小板预活化和纤维蛋白原的差异。结果rotem®分析显示,在接受10°C灌注的参与者中,30分钟后凝血时间延长(平均差异:2.6秒,95% CI: 0.30至4.90)。血栓弹性测量未见其他改变。此外,30分钟后纤维蛋白原水平略有升高。结论:与22°C相比,在10°C下给予乳酸林格氏液可导致血栓弹性测量法评估的30分钟后凝血时间的轻微延长,对止血的影响最小。30min后纤维蛋白原略有升高。我们的结论是,给予1000毫升的冷液体不会显著影响止血,并且在健康成人中被认为是安全的。

期刊介绍: The Journal of Thermal Biology publishes articles that advance our knowledge on the ways and mechanisms through which temperature affects man and animals. This includes studies of their responses to these effects and on the ecological consequences. Directly relevant to this theme are: • The mechanisms of thermal limitation, heat and cold injury, and the resistance of organisms to extremes of temperature • The mechanisms involved in acclimation, acclimatization and evolutionary adaptation to temperature • Mechanisms underlying the patterns of hibernation, torpor, dormancy, aestivation and diapause • Effects of temperature on reproduction and development, growth, ageing and life-span • Studies on modelling heat transfer between organisms and their environment • The contributions of temperature to effects of climate change on animal species and man • Studies of conservation biology and physiology related to temperature • Behavioural and physiological regulation of body temperature including its pathophysiology and fever • Medical applications of hypo- and hyperthermia Article types: • Original articles • Review articles
