摘要: Objective To test the hypothesis that patient-controlled analgesia (PCA) contributes to improvement of hemorheology in patients undergoing hip arthroplasty. Methods 120 patients, aged 60 – 75 years old, arthroplasty under spinal anesthesia, were randomly divided into group PCA (n = 60) and control (n = 60). Patients received postoperative 3 days. Blood samples from median cubital vein collected at five time points: before anesthesia (T1), after surgery (T2), 6 h (T3), 24 h (T4), 48 h (T5). Hemorheological parameters measured, including whole blood viscosity a high shear rate (Hηb), low (Lηb), reduced (ηr), plasma (ηp), hematocrit (Hct), erythrocyte aggregation index(EAI) deformation index (EDI). Noninvasive pressure heart T1-5 pain scoring visual analogue scale (VAS) score T2-5 recorded. Results (1) Compared with T1, Hηb, Lηb, ηp, ηr decreased significantly T3–5 EAI T5 (p Conclusion Postoperative may increase arthroplasty, mainly via viscosity, rigidity, which could be improved by PCA.
