AbstractThe change in maternal hemodynamics during cesarean section has not been well studied. Continuous transthoracic echocardiography can monitor cardiac function continuously. This study aimed to evaluate the effectiveness of maternal hemodynamic parameters monitoring during cesarean section using continuous transthoracic echocardiography. In this prospective, observational study, women with an uncomplicated singleton pregnancy scheduled for elective cesarean section at term under combined spinal-epidural anesthesia were enrolled. Maternal hemodynamic parameters were assessed by continuous transthoracic echocardiography at 11 pre-set time points. The image quality of continuous transthoracic echocardiography was evaluated before measurement was performed. Totally, one hundred parturients were recruited, and transthoracic echocardiography images with sufficient quality for further analysis were obtained in 72 women. Following anesthesia, maternal heart rate decreased by 11.18% and cardiac output decreased by 7.82%, but stroke volume remained stable. After delivery of the neonate and placenta, stroke volume and cardiac output increased by 21.09% and 22.33%, respectively. End-diastolic volume also increased significantly after delivery of the neonate, but end-systolic volume was unchanged. Following delivery of the neonate, fractional shortening increased till the end of the cesarean section while total peripheral resistance decreased significantly. In conclusion, continuous transthoracic echocardiographic monitoring revealed that there were significant changes in hemodynamic parameters during cesarean section after delivery of the newborn and placenta, which warranted further investigation.© 2021.
