Effects of hypothermia (33° vs. 37 C) and haemodilution on the ROTEM EXTEM parameters clotting time (CT), clot formation time CFT) and alpha angle (AA). RAc: Ringer’s acetate, HES: hydroxyethyl starch. All differences between haemodilution groups (Undiluted vs. RAc, Undiluted vs. HES, and RAc vs. HES) within each temperature were significant (P < 0.001), except the differences of CT between Undiluted and RAc at both temperatures, which were not significant. Brackets show significant differences between temperatures. (+: P < 0.05, ++: P < 0.01, +++: P < 0.001). Data are presented as mean values, error bars are 95% simultaneous confidence intervals. N = 10.
