Objectives: Trauma-induced coagulopathy (TIC) can be fatal but preventable if recognised early. With emerging uses of rotational thromboelastometry (ROTEM) to guide transfusions in trauma, patient outcomes with TIC-defined by initial ROTEM and conventional coagulation tests (CCTs) during massive haemorrhage protocol (MHP) activations were evaluated at a primary trauma centre in British Columbia.

Methods: This retrospective observational study included adult trauma patients requiring MHP from June 1, 2020, to May 31, 2022.

Cardiac tamponade is a rare but fatal complication of catheter ablation. We are reporting a case of a 73-year-old male with ventricular tachycardia (VT) storm undergoing urgent VT ablation, who was later found to have right ventricle (RV) perforation-an unusual site for catheter ablation complication. The patient underwent isochronal late activation mapping (ILAM)-based ablation and elimination of local abnormal ventricular activities (LAVA).

Hemoglobin, composed of α- and β-chains, is essential for oxygen transport and is key in diagnosing and treating gastrointestinal and blood disorders. It also aids in detecting blood contamination and estimating transfusion volumes. Immunological methods, based on antigen-antibody interactions, are distinguished by their high sensitivity and accuracy.

Transfusion safety and blood typing continue to present significant challenges in clinical practice, including risks of incorrect blood transfusions and blood shortages. One promising solution is the enzymatic conversion of all red blood cell (RBC) types into universal O-type RBCs. However, the major obstacle to this strategy is the relatively low catalytic efficiency of the enzymes involved.
