目的观察TPN的不同输入对围手术期胃癌患者血黏度的影响。方法将60例病理证实的进展期胃癌患者分为三组,实验组1(G1):20%力能(LCT)提供30%非蛋白热卡;实验组2(G2):20%力能提供30%非蛋白热卡,8h内直接静脉输入;对照组(G3):葡萄糖提供100%非蛋白热卡。能量给予105kJ/kg·d,N0.12g/kg·d,G1和G3营养液以“全合一”液匀速输入。分别于营养前(术后)及营养后测定外周血血黏度和血乳糜微粒。结果G2组血黏度有升高但差异无统计学意义(P>0.05),血乳糜微粒明显升高(P<0.01)。G1和G3两组间差异无统计学意义(P>0.05)。结论力能脂肪乳提供30%非蛋白热卡对老年人血黏度无明显影响,但直接静脉输入血黏度有所升高,血乳糜微粒明显升高,对机体可能产生不利影响。
Objective To observe the effect of different inputs of TPN on the blood viscosity of perioperative gastric cancer patients. Methods Sixty patients with pathologically confirmed advanced gastric cancer were divided into three groups: experimental group 1 (G1): 20% LCT provided 30% non-protein heat card; experimental group 2 (G2): 20% 30% non-protein heat card, direct intravenous infusion within 8h; control group (G3): glucose provides 100% non-protein heat card. Energy was given 105kJ / kg · d, N0.12g / kg · d, G1 and G3 nutrient solution “all in one” liquid uniform input. Peripheral blood viscosity and chylomicrons were measured before nutrition (postoperative) and after nutrition respectively. Results The blood viscosity of G2 group was increased but the difference was not statistically significant (P> 0.05), and the chylomicrons were significantly increased (P <0.01). There was no significant difference between G1 and G3 (P> 0.05). CONCLUSION: The 30% non-protein heat card provided by power lipoprotein has no obvious effect on the blood viscosity of the elderly, but the blood viscosity of the direct intravenous infusion is increased, and the chylomicrons are obviously increased, which may adversely affect the body.
