ABSTRACT
Background: Up to 80% of hospitalized patients require intravenous therapy, making peripheral venous catheters the most widely used endovascular device in hospitals. Peripheral Intravenous Catheters  is a safe device and have a low risk of life-threatening consequences when appropriately used, but it frequently experiences peripheral intravenous catheters problems such as phlebitis and infiltration. aimed : This study aimed to assess peripheral intravenous catheter related phlebitis, infiltration and its contributing factors among patients at Port-Said hospital. Subjects and method: Design: The study design was descriptive. Setting: The study was conducted at the Universal Health Insurance Hospital in Port-Said medical and surgical departments. Subjects: The convenient sample contained (364) adult patients with intravenous catheters.  Tools: Tool I: Contributing factors include four parts (patient characteristics, nurses' characteristics, intravenous characteristics, medication and fluid characteristics).Tool II: Part I Phlebitis Scale, Part II: Infiltration Scales. The Results: This study showed that 45.6% of studied patients developed phlebitis, and 25.5% of them developed infiltration. There were statistically significant relation between phlebitis, infiltration, and patients' age, Type of chronic diseases, nurses' years of experience, the IV catheter site, extension tube, medications as antibiotics, and infusion method.  Conclusion: patients' age, body mass index, type of chronic diseases, nurses' years of experience, the IV catheter site, medications, and infusion method were contributing factors of phlebitis and infiltration.  Recommendations: Provide a continuing continual education for nurses to teach them how to manage IV catheters and the problems of phlebitis and infiltration.
