question: Compared to usual care what was the result of intraoperative goal-directed fluid restriction (GDFR) strategy on heart rate, mean arterial pressure, PETCO2, natremia, and urine output?
context: The ICU length of stay was significantly shorter in the GDFR group (3 days [1–5] vs. 6 days [3–11], p = 0.001) (Fig. 1).
