Application of subspecialty standardized temperature management process in a hybrid surgery for acute aortic dissection

Objective: To evaluate the clinical effect of a subspecialty standardized temperature management process in a hybrid surgery for treating acute aortic dissection.

Methods: From January 2020 to June 2021, 102 patients who underwent hybrid surgery for acute aortic dissection in the Department of Cardiovascular Surgery at the Huai'an First People's Hospital were selected as the control group, receiving routine temperature maintenance measures. From August 2021 to November 2022, 105 similar patients from the same hospital were enrolled in the experimental group, where a subspecialty standardized temperature management process was implemented. The incidence of hypothermia, Grade 4 shivering, and temperature changes at different time points during surgery were compared between the two groups.

Results: The experimental group had significantly lower rates of postoperative hypothermia (7.62% vs. 17.65%, P=0.03) and Grade 4 shivering (0.00% vs. 6.86%, P=0.019) compared to the control group. Furthermore, temperature monitoring at different time points during surgery showed that patients in the experimental group had higher temperatures than those in the control group upon entering the operating room (P=0.000), half an hour after anesthesia induction, at the end of surgery, upon leaving the operating room, and upon leaving the post-anesthesia care unit (all P<0.001).

Conclusion: The implementation of a subspecialty standardized temperature management process in hybrid surgery operating rooms effectively maintains the required body temperature during hybrid surgery for acute aortic dissection, thereby reducing the incidence of postoperative hypothermia and shivering.
