Abstract: Objective: To investigate the patient's clinical practical value of elbow fixed splint applied to enhanced CT examination. Methods: Pre-do enhanced CT examinations of 120 patients were randomly divided into control group(60 cases) and observation group(60 cases). All patients in the control group before performing enhanced CT examination did not use the elbow fixed splints; the observation group before performing enhanced CT examination used the elbow fixed splints, compared the two groups of the incidence of iodine contrast agent leakage and nursing service satisfaction. Results: In the control group, 10 of 60 cases occurred iodine contrast agent leakage, the incidence rate was 16.7%; the nursing service satisfaction rate was 80%. In the observation group, 2 of 60 cases occurred iodine contrast agent leakage, the incidence rate was 3.3%; the nursing service satisfaction was 95%. The incidence of iodine contrast agent leakage in the observation group was significantly lower than that in the control group, while the satisfaction of nursing service was better than that of the control group, and the difference between the two groups was statistically significant(P <0.05). Conclusions: When elbow fixed splint applied to enhanced CT patients, the incidence of iodine contrast agent leakage reduced apparently, and the nursing service satisfaction rate improved a lot. So it is easy for the patients to accept and worth promoting in clinic.
