Objective:To study the importance of nursing cooperation in 16-slice spiral CT contrast enhancement scanning

so as to ensure scanning effect and reduce side reaction.Methods:Clinical records of 2 860 cases underwent 16-slice spiral CT contrast enhancement scanning were analyzed retrospectively.Preparation was done well;patients` reactions were closely observed during scanning;and treatment was performed basing on based on patients` condition.Results:Ninety-three per cent(2 660 in 2 860) of cases presented transient sensation of heat all over the body after injection of non-ion contrast agent;120 cases(4.2%) presented sensation of heat all over the body

bitter taste and itching on perineal region;35 cases(1.2%) presented slight allergic reactions such as sensation of heat all over the body

skin itching

nausea

and urticaria;9 cases presented moderate allergic reactions such as sensation of heat all over the body

urticaria

nausea

vomiting

palpitation

and dyspnea;leakage in pricking region was found in 5 cases(0.1%);none presented severe allergic reaction;and no nursing complications such as skin necrosis and air embolism appeared.Conclusion:Good preparation of nursing care could ensure the effect of contrast enhancement scanning

improve accuracy of diagnosis
