摘要目的：探讨压力再分布气垫预防主动脉夹层手术患者术中获得性压力性损伤（IAPI）的临床效果。方法：选取2021年3月至2022年2月在温州医科大学附属第一医院需行人工血管置换术的主动脉夹层患者随机分为2组，试验组59例，对照组60例，共119例。试验组尾骶部给予自制压力再分配装置预防术中获得性压力性损伤，对照组尾骶部给予凝胶垫和棉垫，比较两组尾骶部皮肤IAPI的发生率、尾骶部皮肤相对温差、护士工作满意度。结果：与对照组比较，试验组IAPI发生率更低（0 vs. 36.7%），尾骶部皮肤与周围正常皮肤相对温差较小[0（-0.1，0.1） vs. 0.3（-0.3，0.5）]，护士工作满意度更高（94.44% vs. 77.14%），差异均有统计学意义（P＜0.05）。结论：术中使用压力再分布气垫能够较好地降低主动脉夹层患者IAPI的发生，减少尾骶部与周围正常组织之间的温度差，提高护士工作满意度。
Abstract：Objective: To evaluate the clinical effect of pressure-redistribution air pad for intraoperative acquired pressure injury in aortic dissection surgery. Methods: Tolly 119 aortic dissection patients who needed aortic arch replacement were selected as research subjects from March 2021 to February 2022 in the First
Affiliated Hospital of Wenzhou Medical University. They were randomly divided into two groups, 59 in the test group and 60 in the control group. The test group adopted pressure-redistribution device to prevent intraoperative acquired pressure injury, while the control group was given pressure protection nursing care with conventional gel pad and cotton pad. The difference in incidence of intraoperative acquired pressure injury, the relative temperature
difference in the sacrococcyx skin and the job satisfaction of nurse between the two groups were compared. Results: Compared with the control group, the test group had lower incidence of intraoperative acquired pressure injury (0 vs. 36.7%), higher job satisfaction of nurse (94.44% vs. 77.14%) and smaller relative temperature difference between sacrococcyx skin and circumference normal skin [0 (-0.1,0.1) vs. 0.3 (-0.3,0.5)], showing statistical difference between the two groups (P<0.05). Conclusion: The use of pressure-redistribution air pad during operation can better reduce the incidence of intraoperative acquired pressure injury in patients with aortic dissection, and produce less temperature difference between the caudal sacrum and surrounding normal tissue, which results in more job satisfaction of nurse. It is a preferable protective measure for intraoperative pressure injury.
