Objective: Central venous line device Port-A-Catheter is convenience for oncology children to receive chemotherapy. Daily intravenous administration through Port-A-Catheter reduces stress on children and family. However, the usage of Port-A-Catheter requires nurses to follow a meticulous sterilized procedure; otherwise, catheter infection and obstruction could occur. The purpose of this paper is to describe process of preventing and solving Port-A-Catheter obstruction.

Methods: To solve the obstruction of the Port-A-Catheter, a detail nursing policy and procedure are developed, and all nursing and medical staffs who will work with oncology children attend a haft day meeting related to Port-A-Catheter problem solving. Urokinase, an anit-cloting agent, is introduced to all staffs to ensure the proper way of administration of Urokinase.

Results: A total of 39 oncology children received Port-A-Catheter placement.  Only 3 children (7.6%) had catheter occlusion. Two catheters obstruction were solved by administrating Urokinase (5,000 unit/ml; 1,5ml each dose).  Port-A-Catheter obstruction caused by blood clot were able be solved by repeat Urokinase administration. One case whose catheter was kinked received a minor surgery to replace the catheter.

Conclusion: Port-A-Catheter is a useful medical device for children to receive long-term chemotherapy. However, it has a small chamber and catheter lumen.  Oncology children use the catheter not only for chemotherapy but also for perenteral nutrition and antibiotic administration.  Therefore, it is necessary to follow the nursing policy and procedure to ensure the safety of using Port-A-Catheter.
