Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to investigate the effect of respectively 10 and 22 degrees Celsius Ringer's lactate solution on the physiological response in healthy adults. In a single center crossover study the investigators will include and randomize 25 healthy volunteers to receive 1 liter of Ringer's lactate either cold (10°C, 50°F), or at room temperature (22°C, 71,6°F) with 100 ml/min. Fluids will be administered through a peripheral vein. After a minimum "washout period" of 24 hours, subjects are switched to receive infusion at the other aforementioned temperatures.

The main outcomes of this study are:

Primary:

• The increase in Mean Arterial Pressure (MAP) 30 minutes after started infusion

Secondary:

* Time until return of MAP to baseline value after infusion.
* Changes in Visual Analog Scale (VAS) of discomfort during infusion
* Changes in temperature, blood pressure, heart rate, peripheral oxygen saturation cardiac index, cardiac output, total peripheral resistance index and stroke volume
* Changes in the intravascular volume status and the fluid responsiveness
* Changes in biochemical parameters at baseline, 30 and 60 minutes.
* Changes in Rotational thromboelastometry (ROTEM) analysis at baseline, 30 and 60 minutes

Trial day 1: Participants receive Ringer's lactate cold (10°C, 50°F), Trial day 2: Participants receive Ringer's lactate at room temperature (22°C, 71.6°F)

Group Type ACTIVE_COMPARATOR

Ringer's Lactate

Intervention Type DRUG

On the first trial day healthy volunteers are randomized to receive 1 liter of Ringer's lactate either cold (10°C, 50°F), or at room temperature (22°C, 71.6°F) with 100 ml/min. After a minimum "washout period" of 24 hours, subjects are switched to receive infusion at the other aforementioned temperatures.
