pathophysiology of elimination
elimination
getting rid of wastes in the body
altered elimination
changes or impairments causing the body to not to get rid of wastes in the body
urinary dysfunction
alterations in urinary motility:
• promotes stasis of filtration in the renal tubes and bladder
• may form due to low flow rate, increased sodium, and low pH
• Precipitation – depositing solid substances from the fluid. May cause blockage of renal structures.
alterations in patency:
• Blockage of urinary passageway can result in obstruction
• Obstructions lead to buildup of pressure behind the blockage
• Can lead to structural damage and impaired function
alterations in neuromuscular function:
• Can result in retention or incontinence.
• Involves neurons of the peripheral and CNS, neurotransmitter production, and the availability/coordination of neural impulses from initiation to action
• Control of urinary elimination can be impaired as a consequence of altered mobility and muscle contractions or relaxation
alteration in perfusion:
• Inadequate arterial blood supply decreased oxygen delivery inability to meet metabolic demands damage to renal structures
• Loss of functional tissue through necrosis leads to pain, bleeding, and obstruction of the venous system
• Stresses the individuals organ system
bowel dysfunction
Alterations in neuromuscular function:
• Loss of coordination and muscular functions leading to alteration in bowel function
• Can result from abdominal surgery, electrolyte imbalances, peritonitis, or spinal trauma
• Often a side effect of narcotic analgesia
• Emotional stress can also alter stool elimination due to the CNS
• Can lead to abdominal distension and pain if the stool is built up as well as intestinal gas
Alterations in motility:
• Increased motility can impair nutrition, preventing adequate time fir nutrient and water absorption, may lead to loss of water and electrolytes
• Decreased motility prolongs storage time in the large intestine which increased fluid loss from fecal matter. May promote the return of waste products to the circulation.
• Composition of bacterial intestinal flora can influence motility within the large intestine.
• Diarrhea and constipation
Alterations in perfusion:
• Can result from focal or global causes.
• Can be reduced or absent to a portion of the bowel due to obstructed flow. May be due to a clot or pressure from a mass.
• Ventilation/perfusion mismatching
• Appendicitis
