      flow chart for hypernatremia




      Formula for fluid replacement therapy in hypernatremia

      Free water deficit
      Free water deficit = 0.6 x body weight (kg) x [(plasma sodium /140) - 1]

      - the free water deficit can be replaced rapidly in acute hypernatremia, which has developed over a few hours; however, it should be replaced slowly in chronic hypernatremia, which has developed over > 2 days (50% replacement in the first 24 hours, and complete replacement in 48 - 72 hours)

      - free water replacement therapy should also take into account the degree of ongoing water loss and/or the balance of sodium and water in the ongoing fluid loss => the treating physician may choose to measure the serum sodium every few hours during the first 12 - 24 hours to ensure that the serum sodium does not decrease faster than 0.5 - 1.0 mEq/L/hour if he is not comfortable using formula to calculate the free water deficit and the precise rate of fluid administration

      - maintenance fluid and electrolyte therapy to maintain urine output and replace insensible losses must also be given in addition to replacement of the free water deficit

      Alternative Formula for fluid replacement

      - the following approach has the advantage that it takes into account the effect of different concentrations of sodium and potassium in the infusate, and it allows one to re-calculate the fluid replacement rate whenever one changes the composition of the infusate solution

      The formula is used to determine the effect of one litre of any infusate on the serum sodium

      1) Formula for infusates containing sodium
      Change in serum sodium = (infusate sodium - serum sodium) divided by (total body water + 1)

      2) Formula for infusates containing sodium and potassium
      Change in serum sodium = [(infusate sodium + infusate potassium) - serum sodium] divided by [total body water + 1]

      Total body water = 0.6 x body weight (kg) for children and non-elderly adult males, 0.5 x body weight (kg) for non-elderly adult females and elderly males, 0.45 x body weight (kg) for elderly females

      Infusate 5% D/W -------- Infusate sodium 0 mmol/L
      Infusate 0.2% NaCl in 5% D/W -------- Infusate sodium 34 mmol/L
      Infusate 0.45% NaCl in H2O -------- Infusate sodium 77 mmol/L
      Infusate 0.9% NaCl in H2O -------- Infusate sodium 154 mmol/L

      Lightbulb Referral criteria for patients with dyspepsia



      Refer: Endoscopy

      Immediate (same day) specialist referral is indicated for patients presenting with dyspepsia and significant GI bleeding (e.g. vomiting large amounts of blood).

      Urgent (within two weeks) specialist referral or endoscopy is indicated for a patient of any age if they present with dyspepsia and any of the following:

      * chronic GI bleeding (e.g. vomiting small amounts of blood, blood in stools)
      * progressive dysphagia (difficulty swallowing)
      * progressive unintentional weight loss
      * persistent vomiting
      * iron deficiency anaemia
      * epigastric mass
      * suspicious barium meal result.

      Routine endoscopic investigation of patients of any age presenting with dyspepsia and without ALARM symptoms is not necessary. However, patients aged 55 years and over should be referred urgently (within two weeks) for endoscopy if dyspepsia symptoms are:

      * recent in onset rather than recurrent and
      * unexplained (e.g. new symptoms which cannot be explained by precipitants such as NSAIDs) and
      * persistent - continuing beyond a period that would normally be associated with self-limiting problems (e.g. up to four to six weeks, depending on the severity of signs and symptoms).
