This study was aimed to explore the anesthesia, analgesia, and nursing intervention scheme for elderly patients undergoing the operation of intertrochanteric fracture of femur under the guidance of ultrasound optimized by blind deblurring algorithm. Fifty elderly patients undergoing intertrochanteric femoral surgery were randomly enrolled into control group (tracheal intubation intravenous anesthesia + routine nursing) and experimental group (ultrasound-guided nerve block anesthesia + comprehensive nursing based on blind deblurring algorithm), with 25 patients in each group. The effects of anesthesia and recovery were evaluated in the two groups. The results showed that the image evaluation index of blind deblurring algorithm was superior to other algorithms (BM3D, DnCNN, and Red-Net), which improved the quality of ultrasound imaging and was more conducive to intraoperative anesthesia guidance. At the beginning and end of intubation and operation, the fluctuation range of mean arterial pressure (MAP) and heart rate (HR) in the experimental group was lower than that in the control group. The maintenance time of sensory and motor anesthesia block (7.53 ± 1.47 h, 5.45 ± 1.36 h) was longer than that of control group (3.38 ± 1.26 h, 3.02 ± 1.31 h). Visual Analogue Scale/Score (VAS) scores at 6 h, 12 h, and 24 h after surgery were lower than those in the control group. The effective rate of nursing and the incidence of complications (92% and 8%) were better than the control group (80% and 16%), and the difference was statistically significant ( < 0.05). In summary, the optimization effect of blind deblurring algorithm was good, which can improve the quality of ultrasound-guided surgery and help in the smooth implementation of surgery. Moreover, nerve block anesthesia and comprehensive nursing were of great value in postoperative analgesia and recovery of patients.
本研究旨在探讨在超声优化的盲去模糊算法指导下，对老年股骨粗隆间骨折手术患者进行麻醉、镇痛和护理干预方案。将 50 例股骨粗隆间手术患者随机分为对照组（气管插管静脉麻醉+常规护理）和实验组（超声引导神经阻滞麻醉+基于盲去模糊算法的综合护理），每组 25 例。评估两组麻醉和恢复效果。结果表明，盲去模糊算法的图像评价指标优于其他算法（BM3D、DnCNN 和 Red-Net），提高了超声成像质量，更有利于术中麻醉引导。在插管和手术开始和结束时，实验组的平均动脉压（MAP）和心率（HR）波动范围低于对照组。感觉和运动麻醉阻滞的维持时间（7.53±1.47 h，5.45±1.36 h）长于对照组（3.38±1.26 h，3.02±1.31 h）。术后 6、12 和 24 h 的视觉模拟评分（VAS）低于对照组。护理有效率和并发症发生率（92%和 8%）优于对照组（80%和 16%），差异有统计学意义（<0.05）。综上所述，盲去模糊算法的优化效果良好，可提高超声引导手术的质量，有助于手术的顺利进行。此外，神经阻滞麻醉和综合护理对患者术后镇痛和恢复具有重要价值。
