To explore the application of comprehensive nursing based on the "3P model" in the interventional treatment of patients with acute aortic dissection.

A retrospective analysis of 81 patients with acute aortic dissection treated in our hospital from January 2023 to December 2024 were retrospectively conducted, including 48 males and 33 females; The age ranged from 20 to 62 years, with an average of (56.91±12.57) years. According to the nursing methods, they were divided into observation group (n=41) and control group (n=40). The control group was given routine nursing, while the observation group was given comprehensive nursing based on "3P mode" on the basis of the control group. The rehabilitation process, visual analogue scale (VAS) score, oxygenation index, forced vital capacity (FVC), forced expiratory volume in one second (FEV1) level and the incidence of adverse reactions were compared between the two groups.

There was no significant difference in the time of getting out of bed and hospitalization between the two groups after surgery (P>0.05). After 7 days and 14 days of nursing, the VAS scores of both groups decreased, which in the observation group was lower than that in the control group (P<0.05). After 7 days and 14 days of nursing, the levels of oxygenation index, FVC, and FEV1 increased in both groups, which in the observation group were higher than those in the control group (P<0.05). The total incidence of adverse reactions in the observation group was lower than that in the control group (P<0.05).

The comprehensive nursing based on the "3P model" can promote patient recovery, improve cognitive function and quality of life in the interventional treatment of acute aortic dissection.
