[Preoperative preparation of pregnant with hypertension according to state of the autonomic nervous system and circulatory system].Anesteziol Reanimatol. 2010 Nov-DecAR
Pregnancy in patients with hypertension is considered in the spotlight of creation of general adaptation syndrome. According to evidence, when a stable hypertension in pregnant patients with hyper- and eukinetic types of haemodynamics is observed, the response of circulatory system and body fluid compartments has a moderate difference with normal. In pregnant patients with hypertension and a hypokinetic type of haemodynamics and pregnant patients with gestosis developed against the background of eukinetic type of hypertension, a physiological decrease of total peripheral resistance (TPR) is absent, which contributes into interstitial hyperhydration. In pregnant patients with gestosis developed against the background of hypokinetic type of haemodynamics, a pathological rise of TPR occurs, which is followed with a more significant interstitial hyperhydration. A differentiated preoperative preparation of pregnant with hypertension with the calcium antagonists and hydroxyethyl starch solution (130/0,4) favours the conversion of hyper- and hypokinetic types of haemodynamics to eukinetic, forms a physiological type of sympathicotonia and improves the water-salt metabolism.
