摘要:Rate of catheter related thrombus formation is 66% in chemotherapy receiving patients while 32% in patients suffering from other disorders. Heparin lock flush is used to flush an intravenous catheter which helps to prevent clot in the tube after intravenous infusion. Therefore, an experimental study was undertaken to assess the effectiveness of heparin lock flush in prevention of chemotherapy induced thrombophlebitis by Baxters scale among patients receiving chemotherapy at selected hospital of Indore. Research design was post test only control group design and sample size was 40 patients receiving 3 day chemotherapy cycle selected by using random sampling (lottery method). Comparison among experimental and control group in terms of development of chemotherapy induced thrombophlebitis in 3 days cycle of chemotherapy, the 2 Value was 6.82(P 0.01). The findings inferred that heparin lock flush is effective in reducing the development of chemotherapy induced thrombophlebitis.
