Maternal hemodynamics during cesarean delivery assessed by whole-body impedance cardiography.
This descriptive study was designed to evaluate maternal hemodynamics and cardiovascular responses to delivery during cesarean section (CS) under spinal anesthesia. We also assessed the feasibility of a noninvasive and continuous method of measuring cardiac output, namely whole-body impedance cardiography (ICG(WB)), during elective CS. Because of the techniques used in previous studies, only fractionated data on maternal hemodynamics during CS are available to date. ⋯ Sudden and significant hemodynamic changes take place at the moment of delivery. Intact physiological cardiovascular compensation mechanisms are needed to adapt to these challenges. Whole-body impedance cardiography may offer a useful noninvasive tool to monitor hemodynamics during cesarean section.
