Multicenter Study Observational StudyVolume status and volume responsiveness in postoperative cardiac surgical patients: an observational, multicentre cohort study.
The best strategy to identify patients in whom fluid loading increases cardiac output (CO) following cardiac surgery remains debated. This study examined the utility of a calculated mean systemic filling pressure analogue (Pmsa ) and derived variables to explain the response to a fluid bolus. ⋯ The mean systemic filling Pmsa enabled a comprehensive interpretation of fluid responsiveness with volume efficiency useful to explain the change in CO as a continuous phenomenon.
