and amputation Right arm, NPO 6 hr, ht 35%

4. •Male, 40 yo, 60kg, ht 40%, for emergency
debridement and amputation

5. Osmosis
•Osmosis is the movement of water (solvent
molecules) across a semipermeable membrane
from a compartment in which the nondiffusable
solute (ion) concentration is lower to a
compartement in which the solute concentration
is higher (Ganong 2003)

7. Osmotic pressure
•Is the pressure that must be applied to the
side with more solute to prevent a net
movement of water across the membrane to
dilute the solute
•Is the amount of force needed to keep water
from flowing across that membrane

8. •Osmolality is the number of particles (osmoles) in
a kilogram of fluid; (konsentrasi suatu larutan
yang diekspresikan sebagai sejumlah partikel per
Kg)
•Osmolarity is the number of particles in a liter of
fluid.
•These terms are often used interchangeably
because the density of water is 1 kg/L.
•Normal serum osmolarity is around 285-295
mOsm/L.

9. •Tonicity, describe the osmolarity of a solution relative
to plasma
•Is a measure of the osmotic pressure gradient of two
solutions seperated by a semipermiable membrane
•Isotonic, solutions that have the same osmolarity as
plasma (no transfer of fluid into or out of cells occurs)
•Hypertonic, those with higher osmolarity (cells shrink)
•Solution that has a higher solute concentration compared
to another solution
•Hypotonic, those with lower osmolarity (cells swell)
•Solution that has a lower solute concentration compared
to another solution

–Whole Blood (M) 66ml/kg, (F) 60 ml/kg

14. In nonobese individuals, the blood volume varies in
direct proportion to the body weight, averaging 70
ml/kg for lean men and woman (stoelting 4

19. •Type of Fluid
– Crystalloid (RL, NS, D5%)
•Small molecules (< 8000 dalton)
– Colloid (Albumin, Dextran, Hetastarch)
•Large molecules (> 8000 dalton)
–Red blood cells (WB, PRBC)
•To increase the oxygen carrying capacity of blood

20. Crystalloid VS Colloid resuscitation

21. •Crystalloid:
–Distributed in the
extracellular fluid
–only 25% of the infused
volume will remain in the
vascular space and expand
the plasma volume

22. •Crystalloids are categorized by their tonicity, a
synonym for osmolality. A fluid that's isotonic has
the same number of particles—the same osmolality
—as plasma.
•Therefore, an isotonic solution won't promote the
shift of fluids into or out of the cells, causing them to
swell or shrink.
•Ringer Asering and lactated Ringer's (LR) solution are
two of the most commonly used isotonic fluids.

23. •Dextrose 5% in water (D
5W) is another isotonic
crystalloid. However, it's not used for resuscitation
because, as its glucose is metabolized, this fluid
quickly becomes hypotonic.
•In fact, D
5
W is a good source of free water. As with
other hypotonic fluids, such as 0.45% NS, the water
quickly shifts out of the vascular bed and into the
cells, by way of osmosis.

24. •Colloid:
–Contain large molecules 
do not readily move into
the interstitial fluid
–At least 75% will remain in
the vascular space
–More effective for
augmenting plasma volume

25. Colloids
Advantages
•Volume expansion
•Longer duration of
action
Disadvantages
•Anaphylaxis
•Expensive
•Poss coagulopathy

26. Crystalloids
Advantages
•Easily available
•Free of anaphylactic
reaction
•Economical
Disadvantages
•Shorter duration of
action

29. SO WHAT IS SHOCK ?

30. Introduction to shock
•Combination of hemodynamic parameters
–Mean Arterial Pressure < 60 mmHg
–Systolic blood Pressure < 90 mmHg
–Clinical: ↓UO
–Metabolic Acidosis

Reverse tissue hypoperfusion

31. SO..SHOCK IS NOT
HYPOTENSION BUT
HYPOPERFUSION
(REDUCED OXYGEN DELIVERY TO MEET
THE OXYGEN CONSUMPTION)

1.There is an Imbalance between the oxygen demand of
the tissue and the oxygen delivery
2.Reduced oxygen delivery is the key factor
(Hypoperfusion)

IS…
To restore the imbalance between oxygen

43. •Atasi penyebab
•Traditional end point of volume
resuscitation
–MAP 65-70mmHg
–Capillary refill time < 2 seconds
–UO > 0.5 ml/kg/hour (adults)
–O2 ssat > 95%
–CVP 8-12 mmHg

44. Estimating the Volume Resuscitation Volume
1.Estimate normal blood volume
2.Estimate % loss of blood volume
3.Calculate volume deficit
4.Determine resuscitation volume

45. •Hb and Hct
–Poor correlation between blood volume defisit
and Hb in acute hemmorrhage, dilutional
decrease in Hb and Hct, NEVER be used to
evaluate acute blood loss Marino PL. The ICU Book 3
rd
ed; 2007:
211-229
•Appropriate treatment of hypovolemia is
volume replacment!!

Kasus:
Seorang laki-laki 55 tahun, 60 kg, datang ke UGD dengan
kesadaran menurun. Riwayat diare dan muntah 1 hari
SMRS.
PF: KU: tampak lemas, Sakit sedang. TD 90/45mmHg, HR
120x/min, RR 25x/min, T 38ºC, mata tampak cekung, bibir
dan mukosa mulut sangat kering, turgor kulit menurun,
lain2 dalam batas normal

50. Case…
• Defisit: 60 kg x 10% = 6 kg = 6 L = 6000 ml
• Bolus: 20 ml x 60 kg = 1200 ml/30 menit
•Membaik atau tidak??
–Membaik, Sisa defisit: 4800 ml
50% (2400 ml) dalam 8 jam pertama + cairan rumatan
50% (2400 ml) dalam 16 jam berikutnya + cairan rumatan
− Tidak membaik,
Ulangi, pikirkan penggunaan coloid, pertimbangkan
penggunaan vasopressor

51. •Step I: focus on emergency management
–IV fluid 20ml/kg isotonic crystalloid
– Additional boluses if needed
•Step II: focuses on deficit replacement
– daily fluid requirements (100-50-20) +
–Fluid deficit
•Total step II:
–½ of the volume administered in 8 hr
–½ of the remainder administered in 16 hr
•Check electrolyte

52. Syok Anafilaktik
•Hentikan pemberian obat atau antigen penyebab
•Baringkan penderita dengan kaki lebih tinggi dari kepala
•Berikan adrenalin sediaan 1mg/1cc, dengan dosis 0.3-
0.5ml IM (Anak 0.01ml/kg) dapat diulang setiap 5 menit
•Pemberian adrenalin dengan IV, kalau pemberian IM
tidak ada respon. Dengan dosis (dewasa) 0.5ml

53. Volume Infusion
A.Catheter Size
The rate of volume infusion is determined by
the dimensions of the vascular catheter, not
the size of the vein
For rapid volume resuscitation, cannulation of
peripheral veins with short catheter is
preferred to cannulation of large central veins
with long catheters

54. Titik Akhir Terapeutik
Capillary refill time < 2 detik
Ekstremitas hangat & warna kulit kemerahan
Produksi urine > 1 ml/kg/jam
Status mental normal
Laktat menurun
Saturasi vena sentral > 70%

59. Conclusion
•Understand the stages of hypovolemic shock
and associated pathophysiological changes
•Early detection of compensated shock so that
fluid can be given adequately
•Know how much fluid must be given
•Indication of blood transfusion
•How to know the success of resuscitation
