Observation on the application effect of power port in cancer patients receiving contrast-enhanced CT scans

Objective To investigate the application effect of Power port in contrast-enhanced CT scans. Methods Totally 220 cancer patients who needed contrast-enhanced CT scans after chemotherapy were selected in Changhai hospital From September 2017 to September 2018, including 110 cases in the observation group and 110 cases in the control group with convenient sampling method.The observation group was injected contrast medium through Power port for CT scans. Contrast medium was injected into the control group by 22G of Peripheral venous access devices (Introcan®). The incidence of contrast medium exosmosis, nursing time and patient satisfaction were compared between the two groups. Results The incidence of extravasation of contrast medium in the observation group was 0, lower than that in the control group 9.1% (10/110), the difference was significant(χ2=10.476,P=0.015); the nursing time in the observation group was (2.60 ±0.15) minutes per time, which was lower than that in the control group (5.60 ± 5.29) minutes per time), the difference was significant (t=5.934, P=0.000); the patient satisfaction in the observation group was higher than that in the control group, the difference was statistically significant (Z=-12.695, P=0.000). Conclusions Contrast medium injection through Power port for CT scans can reduce the incidence of contrast medium exosmosis, reduce nursing hours and improve patient satisfaction.
