“…Patients with lower limb injuries of different degrees, especially those with cardiovascular diseases, are prone to hemodynamic changes during the process of postural positioning, which limits their clinical application. For elderly patients, the implementation of anesthesia and perioperative management should not only meet the needs of the operation but also reduce their impact on the physiological function as much as possible, which is conducive to the early postoperative rehabilitation training [14][15][16].…”

Objective. To explore the effect of continuous lumbar plexus block guided by the “Shamrock method” on postoperative analgesia and hemodynamics in elderly patients after total knee arthroplasty (TKA). Methods. From January 2020 to December 2020 in our hospital, 98 patients who underwent TKA were selected. Using the random number table method, the patients were divided into two groups: a continuous lumbar plexus block group (group L), with 49 patients, and a continuous femoral nerve block group (group F), with 49 patients. The onset time and maintenance time of motor and sensory nerve blocks in patients were recorded. A visual analogue scale (VAS) was applied to assess the pain severity at 6, 12, 24, and 48 h after the operation. The VAS score (FVAS) was applied to evaluate the pain severity of the patients during 24 and 48 h after the operation and knee joint functional exercise. The levels of hemodynamic indexes such as heart rate, mean arterial pressure, and oxyhemoglobin saturation and the levels of hemorheological indexes such as plasma viscosity, high and low whole blood shear viscosity, fibrinogen, and hematocrit were detected and compared between the two groups immediately after the operation and at 12 h and 48 h after the operation, respectively. The incidence of adverse reactions induced by anesthesia was counted. Results. The onset time of motor and sensory nerve blocks in group L was lower than that in group F, and the maintenance time was higher than that in group F ( P < 0.05 ). The VAS scores of 6, 12, 24, and 48 h after operation in group L were significantly lower than those in group F ( P < 0.05 ). The FVAS scores of group L at 24 and 48 h after operation were significantly lower than those of group F ( P < 0.05 ). The heart rates of the patients in the two groups were higher at 12 h and 48 h after operation than those immediately after operation ( P < 0.05 ). The heart rates at 12 h and 48 h after operation in group L were lower than those in group F ( P < 0.05 ). The plasma viscosity, high whole blood shear viscosity, and low whole blood shear viscosity in the group L at 12 h and 48 h after operation were lower than those in group F ( P < 0.05 ). There was no significant difference in the incidence of local anesthetic poisoning, nausea, vomiting, urinary retention, pruritus, and other adverse reactions between the two groups ( P > 0.05 ). Conclusion. The “Shamrock method” ultrasound-guided continuous lumbar plexus block in elderly patients after TKA has good analgesic effect, stable hemodynamics, little influence on hemorheology, and good safety. It is of great value to enhance the surgical effect and promote postoperative rehabilitation.
