Methods:50 cases with lung cancer were enrolled and randomly divided into cold potato chips patching group and the controlled group.The occurrence cases and severity of phlebitis were observed.Results:Phlebitis occurred to 8 cases (28.6%) of the 28 cases in the ice potato chips patching group:red-swelling type occurring to 5 cases and hard-section type,to 3 cases.In the controlled group,phlebitis occurred to 13 patients(59%):red-swelling type occurring to 8 cases; hard-section type,to 3 cases and necrosis,to 2 cases.The incidence of phlebitis in the cold potato chips patching group was significantly reduced(P
