Trial Outcomes & Findings for Point-of-care Management of Coagulopathy in Lung Transplantation (NCT NCT03598907)

NCT ID: NCT03598907

Last Updated: 2025-06-10

Results Overview

Total estimated blood loss measured during the perioperative period of lung transplantation (including intraoperative and immediate postoperative period).

Recruitment status

TERMINATED

Target enrollment

100 participants

Primary outcome timeframe

From the beginning of surgery to 24 hours postoperatively

Results posted on

2025-06-10

Participant Flow

After performing an interim statistical analysis of the results in approximatelly the middle of the study, the project was prematurely terminated as it would have been unethical to continue.

Total number of patients anticipated in the study was 120, meaning 60 patients in every group.

Measure
Standard Management of Coagulopathy
The first group of existing ,,standard care" - the approach to bleeding patient will be based on clinical experience of the anaesthetist, practically meaning administering crystalloids, colloids (hydroxyethyl starch or gelatin), fresh frozen plasma and erythrocytes to restore normovolemia and platelets, fibrinogen, prothrombin complex concentrate, von Willebrand factor, tranexamic acid, all products giving ,,blindly" when it comes to diagnosis and treatment of coagulopathy.
POC Management of Coagulopathy
group of ,,point-of-care" approach to the diagnosis and treatment of perioperative bleeding and coagulopathy will be conducted on the basis of the results of the POC methods ROTEM, PFA 200 and Multiplate (prothrombin complex concentrate, fibrinogen, platelets, von Willebrand factor, tranexamic acid). A solution of 5% albumin and erythrocytes (to keep haemoglobin level over 100 g/l as it is critical for normal primary haemostasis) will be used to keep normal circulating volume and to compensate for perioperative blood loss.

PGD 0-1 and 2-3 differences between POC versus Non-POC group. Primary graft dysfunction (PGD) in lung transplant patients is described as acute pulmonary damage occurring early in lung transplantation. The severity of PGD is defined in four degrees and is evaluated using partial arterial oxygen pressure (PaO2) and inspired fraction of oxygen ratio (FiO2) ratio and simultaneously evaluating X-ray finding of the lungs after surgery. * Grade 0 - PaO2/FiO2 ratio of any value but no pulmonary edema on chest X-ray * Grade 1 - PaO2/FiO2 \> 300 and presence of pulmonary edema on chest X-ray * Grade 2 - PaO2/FiO2 200 - 300 and and presence of pulmonary edema on chest X-ray * Grade 3 - PaO2/FiO2 \< 200 and presence of pulmonary edema on chest X-ray or patients in need of postoperative ECMO support or nitric oxide therapy
