Postoperative hemodynamics and fluid balance data include measurements of blood pressure (BP) in millimeters of mercury (mmHg) and include systolic BP, diastolic BP, and mean arterial pressure (MAP). Heart rate (HR) is presented in beats per minute. Cumulative input and output (I/O) is for the patient’s entire hospital course and is presented in liters (L). Starting at one hour postoperative, the patient was approximately 6 liters positive. Crystalloid and colloid boluses are designated under the same title “bolus,” which is identified by diamonds in the graphs. Vasopressor refers to any vasopressive medication given in the postoperative period and is designated by crosses. Vasopressin and ephedrine were given in the early postoperative period followed by a transition to norepinephrine alone at approximately 4 hours postoperative. Norepinephrine was administered in micrograms per kilogram per minute (μg/kg/min) and was stopped approximately 23 hours postoperative.
