ABSTRACTPurposeShort-term and saturated simulated dives followed by decompression with air, cause a decrease in platelet count and increased activation of fibrinolysis. The aim of this study was to determine whether short-term dives with trimix as a breathing mixture induce the activation of platelets, and/or fibrinolysis.Material and Methods30 male divers were subjected to short-term hyperbaric exposures to 0.7 MPa. Thirty divers used air and then the same divers used trimix as a breathing mixture. Results: The mean platelet count dropped significantly after decompression only in the group breathing air. The number of CD62P positive platelets and the amount of platelet-derived micro particles were statistically significant higher after decompression in both exposures. The number of CD61 positive platelets increased significantly only in the group breathing air. We observed a significant decrease of factor XII and fibrinogen concentrations after decompression only in the group breathing air. A significant increase in the concentration of plasmin-antiplasmin complex in both groups was detected.ConclusionsShort-term hyperbaric exposure and decompression performed according to current safety standards activates platelets and the fibrinolytic system. Trimix protects divers from a reduction in the amount of platelets, fibrinogen and factor XII in the course of these exposures.
