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
2
Q

hemorrhoids presentation

A
Itching / burning
 Pain
 Swelling / inflammation
 Blood - In stool or on toilet tissue after defecating
 Encopresis (fecal soiling)
 Thrombosis - clots
3
Q

how are hemorrhoids classified (generally)

A

External hemorrhoids
 Originate just below the skin of the anus
 Can cause pain
 More likely a source of self-care questions

Internal hemorrhoids
 Higher, in the rectum (just above the pectinate line)
 No pain unless there are complications
 No nerve fibers in this area

4
Q

classify internal hemorrhoids (4)

A

Grade I
 No protrusion of hemorrhoids

Grade II
 Protruding hemorrhoids that spontaneously reduce

Grade III
 Protruding hemorrhoids where it is possible to push them back in manually

Grade IV
 Protruding hemorrhoids that can no longer be pushed back manually

5
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

6
Q

hemorrhoids - red flags

A
 Severe pain
 Rectal bleeding / melena (black tarry stool)
 Fecal soiling / seepage
 Less than 12 years of age
 Family history of colon cancers
 Patients with Grade III or IV hemorrhoids
 Severe prolapse
 No response after 7 days of treatment
7
Q

goals of therapy (3)

A
  • relieve symptoms
  • prevent complications
  • promote good bowel habits, anal hygiene
8
Q

hemorrhoids non-pharm

A
  1. avoid constipation - most important
    - review diet, fiber supplementation, fluids
  2. bowel habits
    - Avoid remaining on the toilet for longer than 1-2 minutes (and avoid straining)
    - Any prolapsed hemorrhoids must be replaced using a
    moistened tissue. After each bowel movement, the anorectal area should be cleaned with mild soap and water and gently wiped with a wet toilet tissue.
  3. Sitz bath 3-4 times daily
    - relieve irritation, itch
    - tub of warm water, sit for 15 minutes at a time, fitted over toilet seat
9
Q

How to increase fiber?

A

grains and cereals:

  • include at least 1 serving of whole grain
  • brown rice, whole grain bread, 5 g of fiber in cereal

legumes and beans
- kidney beans

fruits and veggies

  • fresh fruit, eat peel
  • no juice
10
Q

hemorrhoids pharm

  • purpose?
  • name 5 types of ingredients in combination pdts
  • what are some dosage forms that can be used?
A
  • short term relief of pain, burning, itch, discomfort, not cure
- Combination products include:
 local anesthetics
 Astringents
 anti-inflammatory agents
 Protectants
 Vasoconstrictors

Available as:
 Creams
 Ointments
- creams and ointments preferable to supp.
 Foams - rapid absorption, may not remain on affected area, diff conc in bubbles
 Suppositories
 Prescription, schedule 2 and unscheduled
 Generally use each morning and evening and after each bowel movement

11
Q

protectants

  • name 2
  • how does it work?
A
  • glycerin, petrolatum
  • Form a physical barrier on the skin to prevent irritation, itching, pain, and burning
  • May have a lubricating effect
  • Very safe!
12
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.

13
Q

astringents

name 2
how does it work?
how should zinc be used vs witch hazel?

A
  • Zinc sulfate, witch hazel
     Produce a drying effect, which helps to relieve symptoms, especially itching and burning
     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
14
Q

corticosteroids

name 1
AE?

A

Hydrocortisone

  • Rx available in combination products
  • Onset can take up to 12 hours but effect lasts longer than other therapies

Cautions / adverse effects
 Do not recommend longer than 7 days, however if finding
improvement can use longer (i.e., 2 weeks)
 Long term use could lead to mucosal atrophy.
 Local adverse effects could include skin atrophy with
prolonged use, may mask symptoms of infection

15
Q

hemorrhoids - common OTCs

2 types
