探究思维导图和精细化护理在老年踝关节骨折术中的应用效果。

选取2018年1月至2020年12月于广州医科大学附属第一医院实施老年踝关节骨折术的98例患者为研究对象。按照随机数字表法，分为观察组与对照组，每组49例。对照组给予常规护理，观察组在常规护理的基础上给予思维导图和精细化护理。两组踝关节肿胀程度比较采用卡方检验；两组术前术后疼痛、下床活动时间、平均住院时间比较均采用t检验。

观察组踝关节肿胀程度低于对照组，差异有统计学意义(χ²＝4.804，P<0.05)；观察组术后24 h视觉模拟法(VAS)评分低于对照组、下床活动时间早于对照组、平均住院时间少于对照组，差异均有统计学意义(t＝13.123、13.595、55.273，均P<0.05)。

应用思维导图和精细化护理能提高老年患者掌握踝关节骨折康复关键事项的能力，对改善不良情绪和缓解术后疼痛有帮助，利于下床活动，缩短平均住院时间且对降低踝关节肿胀程度起作用。

To explore the mind map and meticulous nursing of elderly patients with ankle fractures.

A total of 98 elderly patients undergoing ankle fracture surgery in our hospital from January 2018 to December 2020 were selected as the research objects. According to the random number table method, they were divided into observation group and control group, with 49 cases in each group. The control group were given routine care, and the observation group were given mind mapping and refined care on the basis of routine care. The chi-square test was used to compare the clinical efficacy of the two groups, and t test was used to compare the preoperative and postoperative pain, time of getting out of bed, average hospital stay, and fracture healing time between the two groups.

The degree of ankle swelling of the observation group was lower than that of the control group, and the difference was statistically significant (χ²=4.804, P<0.05); the 24 h visual analogue scale (VAS) score of the observation group was lower after surgery, and the time to get out of bed was earlier. The average length of hospitalization was less than that of the control group. The differences were statistically significant (t=13.123, 13.595, 55.273, all P<0.05).

The application of mind mapping and refined nursing care can improve elderly patients′ understanding of the key issues of ankle fracture rehabilitation, help improving bad mood and relieve postoperative pain, facilitate getting out of bed, shorten the average hospitalization and reduce the degree of joint swelling kick in.
