Nursing Care Plan – Hemorrhoids
July 6, 2009 · 1 Comment
Hemorrhoids are vascular masses that protrude into the lumen of the lower rectum or perianal area. They result when increased intra-abdominal pressure causes engorgement in the vascular tissue lining the anal canal. Loosening of vessels from surrounding connective tissue occurs with protrusion or prolapse into the anal canal. There are two types of hemorrhoids: external hemorrhoids appear outside the external sphincter, and internal hemorrhoids appear above the internal sphincter. When blood within the hemorrhoids becomes clotted because of obstruction, the hemorrhoids are referred to as being thrombosed.
