Meranie kardiovaskulárnych parametrov u novorodencov – význam a aktuálne poznatky

Popôrodná adaptácia je zložitý proces, ovplyvňujúci predovšetkým kardiovaskulárny a respiračný systém bezprostredne po pôrode. Tento proces zahŕňa nástup spontánneho a pravidelného dýchania a tiež fyziologické a anatomické zmeny kardiovaskulárneho systému.

Technologický pokrok poskytuje nové možnosti efektívnejšieho a zároveň neinvazívneho monitorovania vitálnych funkcií. Frekvencia akcie srdca je najužitočnejším parametrom, ktorý odráža okamžitý priebeh popôrodnej adaptácie a spolu so saturáciou krvi kyslíkom patrí k štandardnému monitorovaniu procesu adaptácie. Nové technológie, ako variabilita frekvencie akcie srdca a infračervená spektroskopia, boli pomerne nedávno implementované do neonatologického klinického výskumu aj praxe.

Lepšie porozumenie fyziológii a patofyziológii mechanizmov popôrodnej adaptácie môže byť nápomocné v prispôsobení preventívnych a terapeutických postupov, a tým minimalizovaní ich nepriaznivých vplyvov, predovšetkým u extrémne nezrelých novorodencov. V predkladanom článku sú prezentované najnovšie údaje o monitorovaní hemodynamických a kardiovaskulárnych parametrov v priebehu včasného i neskoršieho popôrodného obdobia.
