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
MAP (1S + 2D)3
Pulse Pressure (S-D)Heart RateCapilary refill timePeripheral VasoconstrictionOxygen saturation
MAP (mean arterial pressure) 70-105 mmHg HR (heart rate)
Neonates ( 0-30 days): 70 - 190 /minute Infants (1 - 11 months): 80-120 /minute Children 1 to 10 years: 70 - 130 /minute Children> 10 years and adults 60-100 minutes
Pulse Pressure (Systolic-Diastolic ) 30-40 mmHg CRT (capillary refill time) < 2 detik Partial Pressure of Arterial Oxygen (PaO2) 80-100

Resuscitation Fluid Therapy
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
Repair 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
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
A 62 year old patient was admitted because of malaise and fatigue after nausea and vomiting for 5 days. Lack of eating and drinking due to anorexia.History of hypertension and taking medication: Tenormin 50 mg, Aspirin 75 mg HCT 25 mg, Lisinopril 40 mg per day

How will you correct the hypokalemia in this patient
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
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
Hypokalemia( 2 - > 2.5 mEq/L )
80 mmol K+ per day
How about life-threatening Hypokalemia?Serum K+ < 2 mmol/L
– Alkalosis– Arrhythmia– Respiratory paralysis– rhabdomyolisis

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
