The predictive ability of carotid artery corrected flow time and respirophasic variation in blood flow peak velocity measured by ultrasonography for fluid responsiveness in parturients for cesarean delivery.
Ultrasonic measurements of carotid artery corrected flow time (FTc) and respirophasic variation in blood flow peak velocity (ΔV
peak ) were recently introduced to predict fluid responsiveness in non-obstetric patients. We designed the present study to evaluate the performance of these two ultrasonic indices in predicting fluid responsiveness in healthy parturients. ⋯ Compared with IVCins , IVCexp and IVCCI, FTc and ΔVpeak measured by ultrasonography seem to be the highly feasible and reliable methods to predict fluid responsiveness in parturients with spontaneous breathing undergoing elective cesarean delivery. -

The assessment of esophageal pressure using different devices: a validation study.
Although esophageal pressure measurement could help clinicians to improve the ventilatory management of acute respiratory distress syndrome (ARDS) patients, it has been mainly used in clinical research. Aim of this study was to compare the measurements of end-expiratory esophageal pressure, end-expiratory transpulmonary pressure and lung stress by three systems: a dedicated manual device, taken as gold standard, a new automatic system (Optivent) and a bedside equipment, consisting of a mechanical ventilator and a hemodynamic monitor. ⋯ Both Optivent and the bedside system showed clinically acceptability if compared to the gold standard device. The possibility to apply one of these systems could allow a wider use of esophageal pressure in clinical practice.
