Abstract: Haemostasis is a waterfall of physiological phenomena, overlapped in time, that appear during the haemorrhage stopping by vasomotor, thrombocyte and plasmatic mechanisms. The haemostasis system includes: the primary and secondary haemostasis (coagulation). The primary haemostasis represents a succession of reactions that induce a temporary stopping of bleeding allowing the realization of the conditions needed to forming the final clot. Primary haemostasis includes parietal and thrombosis time. Parietal time- is represented by the phenomena through which the blood vessel lumen decreases thus reducing or temporary stopping the bleeding of the injured vessel. Thrombosis time - represented by the thrombocyte “the morphological dwarf, the physiological giant” that under normal conditions does not adhere to unimpaired endothelium with the white thrombocyte formation in peripheral vascular bed. Primary haemostasis research, detection of the precocious disturbances and interference in due time, forewarn the decomposition of vaso-thrombosis mechanism and the protection of plasmatic mechanism. Hemostaza este o cascadă de fenomene fiziologice, suprapuse în timp, care îşi dau concursul la oprirea hemoragiei prin mecanisme vasomotorii, trombocitare şi plasmatice. Sistemul de hemostază include: hemostaza primară (timpul vaso-plachetar) şi hemostaza secundară (coagularea).Hemostaza primară (timpul vaso-plachetar) reprezintă o succesiune de reacţii care induc oprirea provizorie a sîngerării, permiţînd realizarea condiţiilor necesare formarii cheagului definitiv. Hemostaza primară include timpul parietal şi trombociatr. Timpul parietal este reprezentat de fenomenele prin care lumenul vasului se micşorează, reducând sau stopând momentan hemoragia din vasul lezat. Timpul trombocitar- reprezentat de trombocit ,,piticul morfologic, gigantul fiziologic”, care în condiţii normale nu aderă la endoteliul intact cu formarea trombului alb trombocitar in patul vascular periferic. Cercetarea hemostazei primare, detectarea perturbărilor precoce şi intervenirea la timp, previn decompensarea mecanismului vaso-trombocitar şi protecţia mecanismului plasmatic.
