HYPERMAGNESEMIA (electrolyte imbalance)

HYPERMAGNESEMIA 


  • It is an electrolyte disorder in which there is a high level of magnesium in the blood
  • Death due to Asystole


CAUSES:

  • CKD - chronic kidney disease
  • Eclampsia Mgso4 toxicity
  • Antacids/Laxative abuse

PATHOPHYSIOLOGY:
  • Increase magnesium → inhibit PTH release -↓calcium→blood vessel relaxation
  • neuromascilar excitability↓ - so reflexes decreased

CLINICAL FEATURE:

  • Shock - non responsive to vasopressors and IV fluid
  • DTR↓ ,Respiratory rate↓,co2↓
  • urinary output↓
TREATMENT:
  • Vigorous IV hydration
  • Ca gluconate
  • Hemodialysis

METABOLIC ALKALOSIS (electrolyte imbalance)

Image
METABOLIC ALKALOSIS It is a metabolic condition in which the PH of tissue is elevated beyond the normal range (7.35-7.45) In chronic vomiting, loss of water + HCL(Hypochloremia) ↓ Dehydration ↓ GFR decreased and the activation of RAAS(renin angiotensin aldosterone system) ↓  increase aldosterone ↓ Hypokalemic hypochloremic metabolic alkalosis CAUSES: Congenital hypertropic pyloric stenosis Ca stomach Healed peptic ulcer disease TREATMENT: Normal saline(0.9%) - so it is saline/chloride responsive metabolic alkalosis but if still PH > 7.55 in spite of fluids give NH4CL (Ammonium chloride)  HYPOKALEMIC METABOLIC ALKALOSIS - CHLORIDE NON RESPONSIVE METABOLIC ALKALOSIS CAUSES :  Nephrotic syndrome protein losing enteropathy eg: celiac sprue CHF Cirrhosis TREATMENT: Spironolactone and restrict salt intake

CONGENITAL NEPHROTIC SYNDROME It is a rare kidney disease which manifests in infants during the first 3 months of life and it characterized by high level of proteins in urine - NPHS1 gene - Nephrin decreased zipper mechanism block defect - NPHS2 gene - Podocin decreased (bad prognosis) CLINICAL FEATURES: Non immune hydrops fetalis Anasara Foamy urine WORKUP: 24 hrs urinary protein = increased = >40mg/m2 BSA Serum albumin - decreased TREATMENT: Daily albumin infusion Steroids

HYPOKALEMIA(electrolyte imbalance)

Image
HYPOKALEMIA It is a low level of potassium(k ๋) in blood serum normal potassium level 3.5 - 5mmol/L Death can occur due to  respiratory muscle paralysis CAUSES: Decrease intake Alkalosis : Potassium shift into cells Sympathomimetics stimulation - trauma, thyrotoxic periodic paralysis, beta 2 agonist toxicity(salbutamol) Renal loss - excess aldosterone = conn's syndrome,bilateral adrenal hyperplasia, ascites , CHF                   - Barter's , Gitelman syndrome                                                                                                       - Salt wasting nephropathy                    ...
