NCLEX 준비 - Phlebitis vs IV infiltration

Phlebitis: 정맥에 생기는 염증성 질환으로, 정맥 판막이 손상되거나 정맥류에 의해 기능을 상실하면 생기게 되며 혈전이 동반합니다.
- the site of a client'speripheral intravenous (IV) catheter was red, warm, painful, and slightly edematous near the insertion point of the IV catheter.
 
- The pH of IV solutions is a measure of acidity or alkalinity and usually ranges from 3.5 to 6.2. Extremes of both osmolarity and pH can cause vein damage, leading to phlebitis. The signs of phlebitis include warmth, tenderness, erythema, and swelling in the affected region. If this occurs, the nurse should discontinue the IV line and insert a new IV line at a different site.

IV infiltration: 수액이 피하조직 속으로 스며든 것을 의미한다. 바늘이나 카테터가 혈관 밖으로 빠져 나온 경우(Extravasation), 또는 정맥으로 주입된 수액이 정맥에서 피하조직으로 샜을 경우(Leakage)에 발생
-  Infiltration occurs when an IV solution leaks into the tissues around the vein. Early signs of infiltration include swelling, coolness, tingling, or redness.
