Abstract:
Objective To investigate the prognostic value of stroke volume variation (SVV) in patients with severe sepsis after early goal-directed therapy (EGDT). Method Thirty-eight mechanically ventilated patients with severe sepsis underwent EGTD were divided into high SVV (≥10%) group and low SW (< 10%) group according to the data obtained from pulse contour continuous cardiac output (PiCCO) analysis device. The differ-enees in the rate of 28-day survival, length of ICU stay, duration of meehanical ventilation and eomplieation of in-fection between two groups of patients were compared. The rate of 28-day survival of patients was analyzed by using Kaplain-Meier survival analysis, and the relationship between SVV and mortality within 28 days was analyzed by using logistic regression model. Results In comparison with low SVV group, the rate of 28-day survival of high SVV group was signifieantly increased (87.5 % vs. 57.1%, P = 0.032), the length of ICU stay was significantly shortened (27.1±9.2) vs. (41.6±10.0) (P = 0. 004) and duration of mechanical ventilation was significantly more brief (20.4±7.3) vs. (28.5±8.3) (P = 0.038). The rate of cumulative survival of patients in high SVV group was higher than that in low SVV group. In addition, logistie analysis showed SW < 10% increased the risk of 28-day mortality (OR = 3.97; 95% CI 1.63 - 9.21, P = 0. 014). Conclusions The SVV can be served as a prognostic indicator in patients with severe sepsis after EGDT.
