Total Parenteral Diet (TPN):

Infusion of intravenous nutrition (macro- and micro- nutrients)

Those with contraindications to oral diet approach

Specialised mixtures of amino acids, dextrose, lipid emulsions, electrolytes, minerals and vitamins

Infused centrally into internal jugular or subclavian blood vessels

INDICATIONS: comatose, inadequate GI function, completebowel rest, and paediatric disorders

ADVERSE ISSUES: infections, post-op wound complications, immune endanger, fluid/electrolyte discrepancy, GI blood loss, etc .

(Arya et ‘s., 2013)

What is hypokalemia?

Hypokalemia:

Normal Results: 3. your five 5. 0 mEq/L

Important Values: &lt, 2 . 5 mEq/L

Potassium (K+), essential part of necessary protein synthesis and maintenance of normal oncotic pressure and cell electrical neutrality

(Pagana & Pagana, 2013)

Signs and Symptoms of Hypokalemia

Commonly not present until Potassium levels are much less than several. 0 mEq/L

Signs and symptoms of hypokalemia are normally related to heart failure, skeletal, and smooth muscle weakness

CARDIOVASCULAR: flattened T-wave and visible U-wave, STREET segment despression symptoms, conduction abnormalities, dysrhythmias, worsening hypertension, abrupt death

KIDNEY: polyuria, hypokalemic nephropathy, improved risk of nephrolithiasis, and chloride-depletion metabolic alkalosis

CNS/NEUROMUSCULOSKELETAL: tiredness, malaise, hyporeflexia, weakness, cramping, paralysis, myalgia, and rhabdomyolysis

GI TRACT: Constipation, throwing up, prolonged gastric emptying, paralytic ileus, beoing underweight, worsening hepatic encephalopathy

GU TRACT: hypotonic bladder

PULMONARY: respiratory acidosis, respiratory failing

ENDOCRINE: insulin amount of resistance and disability in insulin release

(Asmar et ‘s., 2012, Elgart, 2004, Pagana & Pagana, 2013)

Tips on how to treat hypokalemia?

Treatment Options:

GOAL: identifying defined cause of hypokalemia, prevent the progress life-threatening consequences, and correct any potassium shortage which steering clear of hyperkalemia

SLIGHT MODERATE HYPOKALEMIA (3. 0 3. 5 MEQ/L):

Handle underlying disorder if possible

Deal with with sixty 80 mEq/d of KCl via PO in divided doses

Reassess serum potassium focus after alternative therapy and adjust consequently

SEVERE HYPOKALEMIA (&lt, several. 0 MEQ/L):

Preferred: 40 mEq/d of KCl through PO q3-4h TID

Reflect on serum potassium concentration after replacement therapy and adjust accordingly

If necessary: 10 20 mEq/h of KCl through IV (in setting of cardiac arrhythmias, recent or ongoing cadiac ischemia, and digitalis toxicity

Continuous heart monitoring is mandatory

Reassess serum potassium focus q2-4h (ensure that serum potassium attentiveness is &gt, 3. a few mEq/L)
