Table 2 Comparison of routine cardiovascular variables and tidal volume between responders and non-responders

From: Neither dynamic, static, nor volumetric variables can accurately predict fluid responsiveness early after abdominothoracic esophagectomy

Hematocrit (%)	Pre	30.9 ± 4.4 (29.5, 27.4-32.7)	30.4 ± 4.0 (29.8, 27.7-32.1)	0.855
	Post	27.5 ± 4.1 (26.7, 24.5-29.6)^b	27.9 ± 4.1 (27.6, 25.5-29.8)^b	0.661
Tidal volume (mL/kg)^d		9.0 ± 1.0 (8.8, 8.3-9.4)	8.8 ± 0.8 (8.5, 8.1-9.3)	0.342

Data are presented as mean ± SD (median, interquartile range).
^aBetween responders and non-responders.
^bP <0.001 as compared with pre-fluid loading.
^cP <0.05.
^dPer kg of ideal body weight.
Pre, Immediately before volume loading; Post, 10 min after volume loading.
