Effects of Lumbar Plexus Block Combined with Infiltration Anesthesia on Anesthesia Comfort Scores and Stress Responses in Elderly Patients Undergoing Hip Replacement

Abstract

Objective. To investigate the effects of lumbar plexus block combined with infiltration anesthesia on anesthesia comfort scores and stress responses in elderly patients undergoing hip replacement. Methods. The materials of 100 elderly patients undergoing hip replacement who were treated in our hospital (January 2020-January 2021) were retrospectively analyzed, and they were equalized into the experimental group (n=50) and control group (n=50) according to the anesthesia methods. The experimental group received lumbar plexus block combined with infiltration anesthesia, and the control group received combined spinal-epidural anesthesia combined with infiltration anesthesia. The patients' anesthesia comfort scores, stress responses, and postoperative pain indexes were compared between the two groups. Results. Compared with the control group, the experimental group achieved much lower scores of mood change, shivering response, and traction reaction (P<0.001), indicating that the anesthesia comfort in the experimental group was higher. Compared with the control group, the experimental group had much better perioperative stress response indexes (P<0.05) and eminently lower pain scores at 12 and 24 hours after surgery (P<0.05). Conclusion. Lumbar plexus block combined with infiltration anesthesia can relieve the stress responses and postoperative pain of elderly patients undergoing hip replacement and increase their anesthesia comfort. Therefore, this anesthesia method is translational in clinic.
