Abstract:
Objective To explore the influence of autologous blood salvage on the gastric intramucosal pH(pHi)in operation for orthopedic patients.Methods 40 patients nnderwent orthopedic surgery were randomly divided into two groups(n=20 each).Salvage group received autologous blood transfusion.The pHi was measured by a nasogastric tube air carbon dioxide tension instrument.The blood samples were collected before operation(T0),1 h after operation(T1),2h after operation(T2)and the end of surgery(T3)for the measurement of pHi.The volume of blood recovery,erythrocyte suspension and plasma were counted.Results The volume of erythrocyte suspension and plasma were significantly higher in control group than in salvage group during operation(P＜0.05).There was no obviously different in blood gas indexes in the two groups(P＞0.05).The phi was significantly higher in salvage group[(7.381±0.023),(7.386±0.025)]than those in control group[(7.361±0.022),(7.375±0.024)]at T2 and T3(all P＜0.05).Conclusion Autologous blood salvage could recover loss blood in time,and make pHi decline,and maintain effective circulation,and significantly improved visceral microcirculatory perfusion and oxygenation in patients under went orthopedic surgery.
