Abstract: PURPOSE: To explore the application effect of colorimetric card combined with photography technology in postoperative monitoring of flap transplantation. METHODS: A prospective controlled study was conducted, enrolling 160 patients undergoing flap transplantation in the Department of Oromaxillofacial Head and Neck Oncology, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from January to December 2024. The patients were divided into the experimental group and the control group (80 cases in each group) using a random number table. The control group adopted traditional naked-eye observation to monitor flap blood supply, while the experimental group supplemented with a flap color observation colorimetric card assembly combined with photography technology to assess flap color and blood circulation status on the basis of traditional observation. The inter-observer consistency between doctors and nurses, incidence of flap crisis, timely detection rate of crisis, flap survival rate, and medical staff recognition were compared between the two groups. RESULTS: The inter-professional observational consistency of the experimental group (97.5%, 78/80) was significantly higher than that of the control group (76.3%, 61/80) (P<0.001). When comparing the incidence of flap crisis and flap survival rate between the two groups, there was no significant difference (P>0.05); however, the timely detection rate of flap crisis in the experimental group (84.6%, 11/13) was significantly higher than that in the control group (23.5%, 4/17, P<0.001). The evaluation of inter-professional recognition showed that the accuracy of nurses' reports and the collaboration of the medical team in the experimental group were significantly better than those in the control group (P<0.05), while there was no significant difference in the dependence on clinical decision-making between the two groups (P>0.05). CONCLUSIONS: The colorimetric card combined with photography technology is easy to operate, which can significantly improve the timely detection rate of flap crisis and inter-observer consistency between doctors and nurses, and promote doctor-nurse team collaboration, thus having high clinical promotion value.
