Abstract:
Objective To observe the relationship between degree of venous injury and the indwelling time by injection of chemotherapy drugs with intravenous catheter system. Methods Totally 43 New Zealand rabbits were selected as the study sample. Among them, three rabbits were chosen by lot as a blank control, the others were evenly divided into two groups randomly. The veins at the edges of the two ears were taken out as the tested blood vessels for the infusion with intravenous catheter system. The two groups were injected respectively with physiological saline and chemotherapy drugs once daily, and then blocked with heparin salt water. After intraperitoneal anaesthesia, pathological sections were prepared by taking live samples from the ear vein where intravenous catheter system puncturing on the 2nd, 4th, 6th,8th and 10th day of transfusion. And inflammation and thrombosis in the vein had been observed under the light microscope. Results In the same indwelling time, the inflammatory response of the two groups was compared: no difference on the 2nd day; difference was seen on the 4th、6th and 8th day; but again no difference on the 10th day. Thrombosis compared: no difference on the 2nd, 4th day, but difference was seen on the 6th, 8th and 10th day. Conclusions Chemotherapy drugs has a strong irritant on blood vessels.The indwelling time should not be too long, generally advisable 2 days,even if no abnormal response is observed locally by the naked eye.
