Abstract

Objective To investigate the applicability of stroke volume variation(SVV) in acute non-normovolemic hemodilution. Methods Sixty patients were enrolled in this study who were scheduled to receive elective surgery at our hospital between March 2017 and December 2017 under general anesthesia. They were randomly divided into the control group (group C) and the observation group (group O), with 30 cases in each group. MAP, HR, SVV, hemoglobin(Hb) and hematocrit (Hct) of the two groups were recorded before blood collection (T₀), upon the collection of 100 ml of blood (T₁), 200 ml of blood (T₂), 300 ml of blood (T₃) and at the end of blood collection(T₄) respectively, so were the duration of blood collection, total colloid collection and the urine volume. Results The levels of SVV[(9.8±1.2)%] at T₄ were higher than at T₀[(5.5±1.3)%] (P＜0.05) in group O, but there was no significant difference between T₀,T₁ and T₃. The levels of MAP at T₂-T₄ were lower than at T₀ while the levels of HR at T₂-T₄ were higher than at T₀ (P＜0.05) in group C, but there was no significant difference between T₀ and T₁. The levels of Hb and HCT in group O were significantly lower than those in group C, while the total volume of blood collection and colloid collection in group O were significantly higher than those in group C(P＜0.05). Conclusions SVV monitoring can better maintain hemodynamic stability than MAP and HR, which is more conductive to acute non-normovolemic hemodilution during surgery.
