Abstract:
Objective To study the application of pressure regulated volume control ventilation in respiratory support after liver transplantation.Methods Twenty patients underwent liver transplantation were randomly averagely divided into two groups: pressure regulated vlume control ventilation(PRVCV) group and volume control(VC) group.The parameters of respiratory mechanics,hemodynamics and blood gas analysis of patients in two groups were compared,such as oxygen delivery(DO2),oxygen consumption(VO2),oxygen incepation ratio(O2ER),arteriovenous oxygen content difference(C(a-v)O2),cardiac output(CO),mean arterial pressure(mABP),mean pulmonary arterial pressure(mPAP),alveolar-arterial PO2 difference(P(A-a)O2),gas exchange index(PaO2/FiO2),ratio of shunted blood to total perfusion(Qs/Qt),peak inspiratory pressure(PIP) and mean airway pressure(mAP).Results The P(A-a)O2 and Qs/Qt were significantly decreased in PRVCV group than those in VC group(P(A-a)O2:(101.42?28.07) mm Hg vs.(136.76?39.13) mm Hg;Qs/Qt:(1.78?0.86)% vs.(3.28?0.99)%),P
