Objective:
To investigate the effects of SF injection on coagulation function, p-selectin and D-dimer concentrations in plasma of elderly patients undergoing total hip replacement (THR).
Methods:
Twenty-four ASA II/III patients aged 65 to 85 were divided equally into two groups (n = 12). In Group S, SF injection was administered by peripheral intravenous infusion at initially 0.2 ml/kg and then 0.8 ml (kg/h) until the end of operations. In Group N, normal saline was administered similarly. All the patients were given patient-controlled epidural analgesia (PCEA) after operations. Blood samples were taken before operations (T(0)), immediately post-operation (T(1)) and 24 h post-operation to detect the levels of p-selectin, D-dimer, blood platelet count and clotting time at all time points.
Results:
The concentrations of p-selectin and D-dimer in Group N increased at T(1) and T(2) while those in Group S decreased at T(1) (P < 0.05). Compared with Group N, they were significantly lower in Group S (P < 0.05). There was no significant difference at T(2) between two groups.
Conclusion:
The plasma concentrations of p-selectin and D-dimer increase obviously in elderly THR patients. SF injection can decrease the plasma concentrations of p-selectin and D-dimer in patients during surgery. Thus it may protect the vascular endothelial cells and attenuate the activation of platelet and fibrinolysis.
