Context

Occlusion

Signs of occlusion include: variable flow; difficulty in aspirating or flushing; pain on infusion; sluggish flow; withdrawal occlusion. Onset can be sudden or gradual.

Occlusion cannot be managed as an isolated event and includes assessing patient risk factors, characteristics of blood and drugs, types of occlusion, and the way occlusion occurs, e.g.:

Note: All catheters become encased with fibrin soon after placement. This transforms to a fibrous collagen substance (Andris and Krzywda, MedSurg Nursing, August 1999). Therefore occlusions should be treated as they become apparent. Thrombi increase the risk of infection (CVC Occlusion: Successful management Strategies, Rhin, Journal of Intravenous Nursing, Volume 22(65) 1999 p 511-517).
