Background/AimsThe effect of acute normovolemic hemodilution (ANH) combined with controlled low central venous pressure (LCVP) on the cerebral oxygen metabolism of patients with hepalobectomy.MethodologyUndergoing hepatic resection operation in 60 cases, were randomly divided into control group, LCVP group (Group II) and ANH + LCVP group (Group IIl). Before hemodilution (T1), decrease of CVP (T2) and increase of CVP (T3) and at the end of surgery (T4), the blood was sampled via the jugular vein bulb and radial artery for blood gas analysis.ResultsCompared with group I, the CaO2 of group II at T3 and T4 was increased; in group III, CaO2 and Da-jvO2 at T2 and T3 were decreased, CjvO2 at T2 decreased, and CaO2 and CjvO2 at T4 increased. Compared with group II, CaO2, CjvO2 and Da-jvO2 of group III at T2 and T3 were decreased. CERO2 of the three groups at T3 and T4 were all decreased (P<0.05 or 0.01). The jugular venous oxygen saturation (SjvO2) and VADL of the three groups at each time point were all within the normal range.ConclusionThe moderate ANH combined with LCVP had no adverse effect on the cerebral oxygen metabolism of the patients with the hepalobectomy.
