[Abstract]Objective:To explore the impact of refined intraoperative instrument management by operating room nurses on the efficiency and safety of HVR surgery.Methods:The study subjects included 110 patients with VHD who underwent HVR treatment at our hospital from June 2024 to May 2026, along with 22 instrument nurses who participated in the surgeries synchronously. Using the random number table method, the enrolled patients and nurses were divided into a control group (55 patients, 11 nurses) and an experimental group (55 patients, 11 nurses). Nurses in the conventional group implemented routine instrument management during surgery, while nurses in the experimental group implemented zoned and refined instrument management during surgery. The surgical efficiency, perioperative safety events of the two groups of patients, as well as the work efficiency and intraoperative instrument management of the surgeries participated by the nurses in the two groups were compared.Results:Under different instrument management modes, the aortic occlusion time, extracorporeal circulation time, intraoperative non-essential waiting time, and total surgical time of patients in the experimental group were all lower than the control group (t=8.817，5.730，20.609，9.632; P<0.05). The incidence of perioperative safety events in the experimental group was 9.09% (5/55) lower than that in the control group 25.45% (14/55) (x2=5.153; P<0.05). The instrument placement time, instrument delivery response time, number of surgical interruptions, instrument sorting time, and instrument handover time of nurses in the experimental group were lower than those in the control group (t=3.347，6.505，5.971，3.795，5.838; P<0.05). The error rate of nurses in the experimental group was lower than the control group (x2=5.238; P < 0.05).Conclusion:Refined intraoperative zone-specific instrument management by instrument nurses enhances surgical efficiency for HVR patients and reduces the risk of perioperative safety incidents, thereby positively impacting the quality of instrument care provided by nurses and preventing instrument-related adverse events.

目的 对比三维中等权重压缩感知并行采集序列（3D IW-CS-SENSE）与常规并行采集序列（3D IW-SENSE）在膝关节磁共振成像中的扫描时间、图像质量及诊断效能。方法 前瞻性采集100例膝关节磁共振影像。对比两组三维序列的定量指标、主观评分以及对损伤分级的准确率。结果 IW-CS-SENSE序列扫描时间显著缩短（122.0 ± 28.0 s vs. 221.0 ± 49.0 s，p<0.001）。IW-CS-SENSE序列信噪比、对比噪声比及显示效果评分均低于IW-SENSE序列（p＜0.001），但IW-CS-SENSE序列的SENSE伪影评分更优（5.00 ± 0.00 vs. 4.59 ± 0.62，p<0.001）。两序列对半月板、韧带及软骨损伤分级的准确率均无统计学差异（p值分别为0.33，0.58和0.15）。 结论 3D IW-CS-SENSE序列可显著缩短扫描时间和消除SENSE伪影，同时保持与4倍加速3D IW-SENSE序列相当的诊断效能。

Objective To compare the imaging times, image quality, and diagnostic performance of three-dimensional (3D) intermediate-weighted compressed sensing sensitivity encoding (IW-CS-SENSE) sequence with conventional 3D IW-SENSE sequence in knee MR imaging. Methods MR images of one hundred knees were obtained prospectively. The quantitative indices, qualitative scores, and grading accuracies between the two 3D sequences were compared. Results Imaging times of IW-CS-SENSE sequences were significantly reduced (122.0 ± 28.0 s vs. 221.0 ± 49.0 s, p < 0.001). The signal-to-noise ratios, contrast-to-noise ratios, and visualization scores of IW-CS-SENSE sequences were significantly lower than IW-SENSE sequences (p < 0.001), while scores of SENSE artefact for IW-CS-SENSE sequences were superior (5.00 ± 0.00 vs. 4.59 ± 0.62, p < 0.001). The accuracies in grading meniscal, ACL, and cartilage tears were comparable between the two sequences (p = 0.33, p = 0.58 and p = 0.15, respectively). Conclusion 3D IW-CS-SENSE sequences can reduce scanning time significantly and eliminate SENSE artefacts, while maintaining the same diagnostic performance as the 4-fold accelerated 3D IW-SENSE sequences.
