Hemorrhoids and Gas Flashcards

1
Q

describe hemorrhoids (piles)

A
  • Pillow like cluster of veins lies beneath mucus membranes lining the lowest part of the rectum and anus
  • Composed of connective tissue, an arteriovenous plexus and suspensory smooth muscle
  • normal anatomic feature that helps with continence
  • diseased when tissue weakens: distal displacement of hemorrhoidal cushions, venous
    distension, bleeding, tissue prolapse, and potential
    thrombosis

Q

hemorrhoids - risk factors

A

Constipation / straining while defecating - blocking venous return from anal canal leading to swollen veins
- shearing of small firm stools causes loosening of underlying connective tissue
 Diarrhea - straining to pause defecation
 Pregnancy - increased ab pressure, increased const
 Spinal cord injury
 Increased abdominal pressure
 Physical exertion or type of work
 Advanced age - tissue tends to weaken and stretch
 Diet - high in white flour, sugar

Q

local anesthetics
name 3
AE?

A
  • benzocaine, dibucaine, petrolatum
  • Offers temporary relief of symptoms by blocking nerve
    transmission
  • Is relatively safe if used for up to 7 days
  • Low absorption unless the skin is abraded

Cautions / adverse effects:
 Evidence of efficacy is lacking
 Can mask the pain of more severe anorectal disorders
 Greater absorption may lead to CNS and CV effects
 May produce local reactions. These may be similar to
hemorrhoid symptoms. Pramoxine has a lower
incidence of this.

     Form a protective layer by coagulating proteins in skin cells of the perianal skin or lining of the anal canal
     Zinc can be used internally or externally on hemorrhoids, while witch hazel should only be used externally
