INTRODUCTION
When a patient is admitted in an emergency or intensive care unit, the immediate intervention carried out is the
insertion of intravenous cannula in order to save the life of the patient. Intravenous therapy is one procedure which is seen
across all the specialties of a hospital. It is a universally acceptable component of medical care. This procedure is so
common that there is a tendency to assume that it is routine and will not be associated with any clinical problems. Thrombo
means clot, Phlebitis means inflammation of a vein. Thrombophlebitis occurs when a blood clot causes inflammation in
one or more of the veins near the surface of the skin. Damage to a vein can occur as a consequence of indwelling catheters,
trauma or the infection of the irritating substances.
Thrombophlebitis is viewed as a natural consequence of routine intravenous therapy and subcutaneous infiltration
of fluid is not always perceived as a serious problem. And it is important for the clinician to be aware of the potential for
injury as a result of medications or fluid leakage into the tissue. An infiltration is not the natural consequence of infusion
therapy alone and every effort should be made to ensure that the infusion will be completed safely without complication
and must use good judgment in site determination, device placement, securing, dressing, care and maintenance.
