The implemented fluid therapy affects coagulation and fibrinolysis, depending on the type of fluid used in an intravenous infusion. Massive haemorrhage significantly impacts the perioperative period and postoperative quality of life and requires individualized therapy, rending the ongoing project relevant from the perspective of the patients.', 'detailedDescription': 'Perioperative bleeding is a complication that significantly affects postoperative morbidity and quality of life and increases the patient\'s risk of death. Massive hemorrhage requires individualized therapy, preferably based on international recommendations. It is necessary to transfuse blood and blood products (red blood cells, freshly frozen plasma, platelets, concentrates of coagulation factors) with simultaneous rational supplementation of the intravascular space using crystalloids and colloids. Usually, these are large volumes that are infused over a short time. Proceedings in the operating room and the intensive care unit environment should stabilize the patient\'s general condition with the lowest possible risk of complications.\n\nHowever, it has been shown that transfusions are not free from side effects. Transfusions may result not only from "classic" post-transfusion complications (allergic reactions, haemolytic reactions, infections, electrolyte disturbances) but also from iatrogenically generated disorders in the circulatory system (fluid overload), respiratory ( acute lung injury), and hemostasis (risk of hypercoagulability). It is also known that uncontrolled and unbalanced fluid therapy per se may additionally affect the haemodynamic state, haemostasis, and the immune system.\n\nThromboelastometry (thromboelastography) is becoming the standard of perioperative haemostasis monitoring. It has been documented that it provides more reliable data than standard laboratory tests, such as fibrinogen concentration, activated clotting time (ACT), kaolin-kephalin (aPTT), prothrombin (PT), or INR index. The test can be performed as the so-called point-of-care test (POC), which reduces the waiting time for the result and facilitates goal-directed therapy.\n\nLittle is known about the effects of fluid infusion on physiological haemostasis in healthy subjects who do not have a prior bleeding disorder and who are infused with fluids similarly to resuscitation in massive bleeding. Only singular studies in international literature attempted to answer this vital question. Still, the regular progress in the field of fluid therapy makes the obtained data less and less valuable in clinical practice.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT'], 'maximumAge': '30 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Healthy male volunteers aged 18-30 years\n* The American Society of Anaesthesiologists Physical Status (ASA PS) I risk class\n* Must be able to give informed consent\n\nExclusion Criteria:\n\n* Female sex\n* Blood type O\n* A positive history of any acute diseases in the last four weeks\n* Chronic diseases\n* Any diagnosed haemostatic disorders\n* History of anticoagulation\n* Any known bleeding diathesis\n* Any pharmacotherapy in the previous week\n* Participants were informed about the prohibition of drinking alcohol, excessive exercise, and stress on the day before blood sampling'}, 'identificationModule': {'nctId': 'NCT05148650', 'briefTitle': 'Impact of Balanced Crystalloid and Colloid Infusion on Haemostasis in Healthy Male Volunteers', 'organization': {'class': 'OTHER', 'fullName': 'Medical University of Silesia'}, 'officialTitle': 'Impact of Infusion of Balanced Crystalloid and Colloid Solutions on Haemostasis in Healthy Male Volunteers- a Randomized Controlled Crossover Trial', 'orgStudyIdInfo': {'id': 'KNW/0022/KB1/159/II/15161819'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Crystalloid infusion', 'description': 'Intravenous (IV) transfusions were performed of a 20ml/kg of a balanced crystalloid solution (Optilyte®, Fresenius Kabi).
