Objective:To investigate the clinical value of applying pain tolerance index(PTi) to guide multimodal analgesic regimen during the perioperative period in elderly hip fractures.Methods:A total of 100 elderly patients with hip fracture admitted to Fuyang People′s Hospital from April 2022 to April 2023 were selected as the study objects. The patients were underwent hip replacement and were divided into two groups according to the different analgesic methods used during the operation. The control group (50 cases) was given routine analgesia during the operation, and the experimental group (50 cases) was given multimode analgesia under the guidance of PTi during the operation. The anesthetic analgesic effect, hemodynamic indexes, inflammatory factors, visual analogue scale (VAS) score, hip function and analgesic drug application were compared between the two groups.Results:The excellent rate of anesthesia and analgesia in the experimental group was higher than that in the control group: 96.00%(48/50) vs. 82.00%(41/50), there was statistical difference ( χ2 = 5.00, P<0.05). The fluctuation ranges of mean arterial pressure (MAP) and heart rate (HR) at the beginning of operation, 30 min after operation and the end of operation in the experimental group were lower than those in the control group ( P<0.05). The serum levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the experimental groups were lower than those in the control group at 1 and 3 d after operation ( P<0.05). The scores of VAS at 24, 48 and 72 h after operation in the experimental group were lower than those in the control group ( P<0.05). The total scores of Harris questionnaire in the experimental group was higher than that in the control group at 6 weeks after operation: (85.93 ± 3.22) scores vs. (75.19 ± 4.18) scores, there was statistical difference ( P<0.05). The intraoperative dosage of propofol and sufentanil and the number of postoperative analgesic drugs in the experimental groups were lower than those in the control group: (430.61 ± 20.09) mg vs. (475.58 ± 23.17) mg, (33.24 ± 8.11) μg vs. (42.90 ± 9.64) μg, (1.54 ± 0.31) times vs. (2.07 ± 0.44) times, there were statistical differences ( P<0.05). The incidence of nausea and vomiting in the experimental group was lower than that in the control group: 2.00% (1/50) vs. 14.00% (7/50), there was statistical difference ( χ2 = 4.89, P<0.05). Conclusions:The application of PTi guided multimodal analgesia in elderly hip fracture surgery has a definite clinical effect, can maintain hemodynamic stability, reduce postoperative inflammatory stress and pain, promote hip joint function recovery, and has certain safety.

Inguinal hernia (IH) is a common complication in prostate cancer patients undergoing radical prostatectomy (RP), which seriously affects their quality of life.The repair of IH is often challenging due to the adhesion in the inguinal area caused by previous surgery.This article focuses on the risk factors for IH after RP, including surgical approach, postoperative anatomical changes, low body mass index (BMI), muscle loss, advanced age, international prostate symptom score (IPSS), and patent sheath process, and prevention strategies for IH after RP, including robot assisted laparoscopic radical prostatectomy (RARP) with IH repair, preservation of the posterior pubic space in RARP, treatment of the spermatic cord, extraperitoneal RARP, and intraoperative management of the sheath like process, aiming to provide reference for urologists and to improve patients' quality of life.
