目的:探讨改良式仰卧位对急诊留观患者压力性损伤的预防效果及舒适状况的影响。方法:选取2019年6月至2020年3月南京医科大学第一附属医院急诊留观病房收治的114例患者为研究对象。按照随机数字表法分为干预组和对照组，每组57例，对照组患者给予常规仰卧位及压力性损伤预防护理，干预组患者在此基础上采用改良式仰卧位护理干预，比较2组患者留观期间压力性损伤发生情况、压力性损伤风险评分评价情况、舒适状况评价情况。结果:干预后，干预组患者压力性损伤发生1例，对照组8例，差异有统计学意义（n Z值为-2.426，n P<0.05）；干预组患者压疮风险评分中的感觉、潮湿、活动能力、摩擦力和剪切力评分分别为（3.36 ± 0.59）、（2.92 ± 0.47）、（3.21 ± 0.52）、（2.61 ± 0.29）分，均明显高于对照组的（2.87 ± 0.51）、（2.24 ± 0.38）、（2.76 ± 0.44）、（2.04 ± 0.32）分，差异有统计学意义（n t值为4.74~9.96，n P<0.01）；干预组患者舒适状况评分中的生理、精神心理维度为（15.41 ± 2.49）、（27.26 ± 3.42）分，均明显高于对照组患者的（11.01 ± 1.97）、（22.14 ± 3.23）分，差异有统计学意义（n t值为10.46、8.21，n P<0.05）。n 结论:改良式仰卧体位护理方式可以降低急诊留观患者压力性损伤的发生情况，改善患者的舒适状况，适合在急诊留观患者中应用。“,”Objective:To discuss the effect of improved supine position on the prevention of pressure injuries of emergency patients under observation and their comfort levels.Methods:A total of 114 patients in our Emergency Observation Ward were randomly divided into the intervention group and control group, 57 patients in each. Patients in the control group were treated with routine supine position and pressure injury prevention nursing; while patients in the intervention group were treated with improved supine position nursing intervention. Then, the incidence of pressure injury, its risk score and its comfort evaluation were compared between patients under observation in the two groups.Results:The incidence of pressure injury of the intervention group was obviously lower than that in the control group (n Z value was -2.426, n P<0.05). The scores of sensation, humidity, activity, friction and shear force of patients in the intervention group were 3.36 ± 0.59, 2.92 ± 0.47, 3.21 ± 0.52 and 2.61 ± 0.29 respectively, which were significantly higher than those in the control group, specifically 2.87 ± 0.51, 2.24 ± 0.38, 2.76 ± 0.44 and 2.04 ± 0.32. The difference was statistically significant (n t value was 4.74-9.96, n P<0.01). In addition, the scores of the physiological and psychological comfort level of patients in the prevention group were 15.41±2.49 and 27.26 ± 3.42 respectively, which were significantly higher than 11.01±1.97 and 22.14± 3.23 in the control group. The difference was statistically significant (n t value was 10.46, 8.21, n P<0.05).n Conclusions:The improved supine position nursing method can effectively lower the occurrence of pressure injury in emergency patients under observation and enhance patients’ comfort degree. Therefore, it is applicable to emergency patients under observation.
