To analyze the influence of shoulder joint exercises and breathing exercises on the rehabilitation of patients with aortic dissection.

A total of 76 patients underwent aortic dissection were randomly divided into the control group (n=38) and the observation group (n=38) from January 2019 to December 2020.The control group were given routine care after surgery, and the observation group adopted shoulder exercises and breathing exercises intervention on the basis of routine care. The differences in blood oxygen saturation (SpO₂), blood lactic acid level (LAC) and muscle strength levels were compared between the two groups of patients after surgery. Chi square test, variance analysis and t test were applied for data analysis.

On the second to third day after the operation, the differences in the SpO₂ levels at six time points between the two groups were statistically significant(F=87.108, P<0.001). The SpO₂ level in the observation group(97.1±0.6)% was higher than the control group (95.1±0.3)%. The LAC level of the observation group was lower than that of the control group on the first to third day after the tracheal intubation was removed(F=20.484, P<0.001).

Shoulder exercises combined with breathing exercises can increase the blood SpO₂ of the patients after aortic dissection thoracotomy and reduce the patient′s LAC concentration, prevent the occurrence of postoperative hypoxemia and effectively promote the recovery of respiratory function.
