Abstract:
Objective To evaluate the effects of arterial pressure continuous output (APCO) derived from stroke volume variation (SVV)-guided fluid management in the patients undergoing supratentorial neoplasms surgery.Methods Sixty-three patients (29 males, 34 females, aged 18-65 years, ASA physical status Ⅰ or Ⅱ) undergoing elective supratentorial neoplasma surgery were randomly divided into control group (group C, CVP-guided fluid management, n=30) and GDT group (group S, SVV-guided fluid management, n=33).Before the induction of general anesthesia, the hydmxyethyl starch Voluven (130/0.4) bolus 3 ml/kg in the two groups was administered followed by infusion of crystalloid at the rate of physical requirement.Hydroxyethyl starch or vasoactive agents were administrated to achieve the goal of CVP≥8 mm Hg or MAP>80% of baseline in group C andto reach the value of SVV≤12% and MAP>70% of baselinein group S.Intraoperativecrystal, intraoperative colloids,total fluid volume, bleeding volume, volume of blood transfusion and urine volume were recorded.The radial artery and venous blood was sampled for blood gas analysis, measurement of lactate concentration and laboratory parameters at 30 min before anesthesia induction (T0), the dura mater cutted (T1), end of operation (T2) and postoperative 24 h (T3).Postoperative complications and the number of patients with complications in postoperative period, the length of ICU stay and postoperative days were assessed.Results Total infused fluid volume [(1 478±312) ml vs (1 183±294) ml] and intraoperative colloids [(775±236) ml vs (487±243) ml] were significantly higher in group S than those in group C (P<0.05).Compared with T0, the lactate concentration were decreased significantly in two groups at T1 and T2.The lactate concentration in group S was significantly lower than group C at T2 [(0.91±0.25) mmol/L vs (1.31±0.46) mmol/L](P<0.05).There was no significant difference of postoperative complications, the length of ICU stay and postoperative days between two groups.Conclusion Fluid management guided by SVV during supratentorial neoplasms surgery reduces lactate levels.
