Anesthetic management of patients with severe pregnancy 4nduced hypertension during cesarean section using the FloTrac/ Vigileo^TMsystem

Objective To evaluate the application of the FloTrac/VigileoTM system to the patients with severe pregnancy- induced hypertension undergoing cesarean section. Methods Twenty-,seven patients with severe pregnancy-induced hypertension scheduled for cesarean section were selected. Mean arterial pressure （MAP）, heart rate （HR）, cardiac output （CO）, cardiac index （CI）, stroke volume（SV）, stroke volume variation（SVV）, stroke volume index（SVI） were measured and recorded at 6 selected time points： preoperation, 5 min after anesthesia, the start of the operation, expulsion, cleaning the peritoneal cavity, the end of operation. Results There were no significant differences in the hemodynamic indexes between preoperation and other time points.. In this study, the CO of patient varied in the range of 3.5 L/min-8.0 L/min, and CI in the range of 2 L·min-1·m-2-4 L·min-1·m-2. Conclusion The FloTrac/VigileoTM system can show the changes of cardiac function in time during operation, which is a safe, reliable monitor for hemodynamic monitoring during cesarean section of patients with severe pregnancy-induced hypertension.
