Haemodynamic changes associated with caesarean section under epidural anaesthesia.
Serial haemodynamic investigations were performed in 15 women delivered by elective caesarean section under epidural anaesthesia at 38-40 weeks gestation. Cardiac output was measured by Doppler and cross-sectional echocardiography at the aortic valve. No haemodynamic changes were demonstrable after attainment of surgical anaesthesia (T5 or above). ⋯ There was a fall in heart rate and cardiac output between the second and the sixth days after delivery. By 2 weeks after delivery cardiac output was 28% lower than pre-operative values. Compared with pre-operative values, diastolic blood pressure was lower on the first and second postnatal days.
