Dehydration vs Hypovolemia

• Intracellular & Interstitial depletion

• Thirst, oliguria, dry mucous membrane

• Plasma Osmolarity ↑• BUN/creatinine ratio >20• FeNa* <1 %

• Intravascular depletion• Hemodynamic responses

in initial phase (compensated shock)

• Hypotension, MAP < 60 indicate advanced stage

Both types often coincides*FeNa = (U/P Na) : (U/P Creat) x 100

Case 1

• A 12 year old patient with DHF. Nausea and vomiting (+)

• PE : restless;T 100/80 T 37.5 oC HR 120 x/min, RR 28 /min; cold extremities. Torniquet test(+). Height 120 cm Weight 50 kg

• Lab: Hct 48%; Platelet 70.000

How is the fluid regimen for this patient?

Answer: Grade 3 DHF requiring 5-10 ml/kg ideal BW /hour and monitor

A 15 kg postop patient with Na+ 97 mEq/L,. PE: Stuporous and convulsion.

How much is Na+ deficit in this patient, if we need to correct it until 125 mEq/L?How will you correct hyponatremia ini this? ; what is the administration rate of 3% NaCl?

Case 2

Page 13: Case-based approach in parenteral fluid therapy

A 15 kg postop patient with Na+ 97 mEq/L,. PE: Stuporous and convulsion.

How much is Na+ deficit in this patient, if we need to correct it until 125 mEq/L?

How will you correct hyponatremia ini this? ; what is the administration rate of 3% NaCl?

Case 2

60% BB x (125-97) = 252 mEq

Infusate Na+– Serum Na+

Total body water + 1

(513-97) : (9+1) = 41.6mE/L

We will raise 1 mmol/L hourly for 5 hours

The amount of 3% NaCl 3% required= 5 : 41.6 = 0.120 L = 120 ml or 24 ml/hourObserve clinical condition and check serum Na+ after 5 hours.. Reduce rate if there is improvement, eg 0.5 mmol/L/hour until Na+ 115.

Case 3

A 9 year old 20 kg patient with dehydration and shock (acute GE), has been resuscitated with Acetated Ringer’s ( Asering) for 5 hours along with separate line of 8.4% Meylon diluted in D5. Patient was then unconscious with seizures.

BP 110/75; HR 90/min ; RR 16/min; T 37oCNa+ 175 mmol/L; K+ 2.1 mmol/L

You wish to correct the hypernatremia and hypokalemia simultaneously with infusion solcontaining 30 mmol/L Na+ (KAEN 4A) plus 20 mmol KCl.

You set a target of Na+ decrease to 165 mmol/L over 10 hours. What is the rate of infusionyou will set up?

You set a target of Na+ decrease to 165 mmol/L over 10 hours. What is the rate of infusion you will set up?

(Infusate Na+ + K+ ) – serum Na+

Total body water + 1

= (30 + 20) – 175(60% x 20) + 1

= -12513

= - 9.6 mmol/LThis means 1 L infusion will decrease the serum Na+ serum by 9.6 mmol/L

Reuired amount of infusion = 5: 9.61 = 0.520 L = 520 ml

over 10 hr give 520 ml, at the rate of 52 ml/hr.Correction rate can be repeated for subsequent 10-14 hours

How will you correct the hypokalemia in this patient

Page 17: Case-based approach in parenteral fluid therapy

Hypokalemia( > 2.5 - <3.5 mEq/L )

Heart /cardiovascular disease?

No Yes

Give K+ according to maintenance requirement 40 mmol

Correction K+ 40 mmol +Maintenance 40 mmol

Page 18: Case-based approach in parenteral fluid therapy

Hypokalemia ( > 2.5-3.4 mEq/L )Without cardiovascular disease

* In case of fluid restrition : admix 10 mmol KCL into 1 bag of KAEN 3B, to get final conc of 20 mmol/500 ml.

40 mmol K+ per day

With cardiovascular disease (digitalis, diuretics)

80 mmol K+ per day

2. What acid-base disorder(s) in this patient?Will you administer sodium bicarbonate ( Meylon)? Respiratory acidosis. Meylon is contraindicated.

3. How will you cope with hyperglycemia? Could you give parenteral glucose at this moment ? • Reduce plasma glucose until 150 mg/dl. (use Yale formula: 240/70 3 U bolus + 3 u eg insulin

drip/hour)• Calculate TDDI (0.3-0.5 u/kg)• Prandial insulin 1 u/10 g glucose
