Changes in estimated stroke volume variation before and after fluid challenge

Responder group (n = 21)
Estimated stroke volume (esSV) (ml) Estimated stroke volume index (esSVI) (ml/m2) Estimated stroke volume variation (esSVV) (%) Systolic blood pressure (sBP) (mmHg) Mean blood pressure (mBP) (mmHg)
Before After  Before After Before After Before After Before After
Mean ± standard deviation (SD) 59.24 ± 11.60 70.24 ± 13.39 35.50 ± 5.30 42.03 ± 5.60 9.03 ± 2.35 9.37 ± 4.78 85.48 ± 10.54 110.29 ± 25.01 59.81 ± 8.52 76.5 ± 17.74
p-value 0.00* 0.00* 0.67 0.00* 0.00*
Non-responder group (n = 22)

Before After Before After Before After Before After Before After
Mean ± SD 65.0 ± 16.62 68.27 ± 16.80 39.37 ± 7.35 41.28 ± 7.14 6.82 ± 2.67 6.95 ± 3.69 90.19 ± 12.37 96.81 ± 17.38 63.43 ± 9.63 67.90 ± 11.69
p-value 0.00* 0.00* 0.81 0.03* 0.04*

Data are presented as mean ± standard deviation values

In both groups, esSVV showed no significant changes (p = 0.67 and 0.81 in the responder and non-responder groups, respectively)

esSV Estimated stroke volume, esSVI Estimated stroke volume index, esSVV Estimated stroke volume variation, sBP Systolic blood pressure, mBP mean blood pressure

*p-value < 0.05 was considered statistically significant
