Tissue that has been subjected to traumatic injury such as physical or chemical damage, caused by instrumentation, pressure, bruising, insufficient blood or oxygen, cytotoxic drugs, desiccation, etc.

Tenderness, erythema, or site induration >2 cm from the catheter site along the subcutaneous tract of a tunneled catheter (e.g. Hickman or Broviac), in the absence of concomitant BSI.

Skin preparation that disrupts the microbial cell wall. Effective against gram positive bacteria and most gram negative (notable exception is pseudomonas). Minimal affect on Tuberculosis and poor activity against viruses. Activity is slow and is minimally effective when in contact with organic matter.

Type of catheter used for venous access; long term, implanted into subclavian, internal jugular or femoral veins, medium risk for CRBSI [less than non-tunneled and more than peripherally inserted central catheter (PICC) line].

A point on the body that is particularly sensitive to touch, and which, when stimulated, becomes the site of painful neuralgia.

Cuff around a catheter that is tunneled through the subcutaneous tissue before entering the target blood vessel. Aid in stabilizing the catheter to prevent pistoning (shifting back and forth). Pistoning increases microbial access along the exterior of the catheter. Thus tunneled cuffed catheters reduce the risk of a CL infection.

Occlusion of the feeding tube often caused by medications, viscous formulas, or insufficient flushing.

Collective name given to the superior and middle nasal conchae of the ethmoid bone, and the paired inferior nasal conchae. The turbinates disrupt the airflow in the nasal cavity, creating turbulent flow, and causing heavier particulate matter to be removed Also moistens and warms the air headed for the trachea and lungs. SEE ethmoid bone; inferior nasal conchae.

Accidental removal or movement of the feeding tube wherein the tip of the tube is not in the gastrointestinal tract where it was originally placed.

An IgE-mediated immediate hypersensitivity reaction, characterized by contact urticaria (hives), angioedema, rhinitis, respiratory complications, drop in blood pressure and rapid heart rate that may potentially progress to anaphylaxis. Severe cases may be fatal. Examples include Type I allergies to the proteins in peanuts, penicillin, shell fish, natural rubber latex, etc. Symptoms appear within minutes to an hour.
