1
Q

what is the goal of shock treatment

A

restoration of oxygen delivery to the tissues

2
Q

what are the clinical signs of dyspnea and hypoxia

A

cyanosis, tachycardia, tachypnea, melena, anxiety

3
Q

what does oxygen therapy depend on

A

duration, demeanor of patient, equipment avail.

4
Q

what are the methods of O2 admin

A

FiO2, flow by oxygen, face mask, oxygen hood/cage, nasal oxygen cannula/ catheter

5
Q

what is the fluid therapy for shock syndrome

A

most effective way to improve O2 deliver - increased CO2 by optimizing vascular volume

6
Q

what are the main 3 types of IV fluids for shock resuscitations

A

isotonic cystalloids, hypertonic saline, synthetic colloids

7
Q

what should we know about isotonic crystalloids

A

fluid with electrolyte concentration and osmolality similar to that of plasma (0.9 NaCl, LRS, PLA 148, Normosal), rapid expanding intravascular volume

8
Q

what are the benefits of isotonic cystalloids

A

inexpensive, long track record of success, ability of redistribution

9
Q

what are the advert effects of isotonic fluids

A

rate of infusion, predisposition of fluid overload

10
Q

what should we know about hypertonic crystalloids

A

cases fluid shift from intracellular and interstitial space into the intravascular space

11
Q

what are the benefits of hypertonic crystalloids

A

when limited support is avail (small vol needed)
possible positive inotropic
immediate effects
decreases intracranial pressure

12
Q

what are the adverse effects of hypertonic crystalloids

A

hypernatremia, hyperchloremia, metabolic acidosis, vasodilation and cardiovascular collapse

13
Q

which patients should we not use hypertonic crystalloids in

A

dehydrated patients

14
Q

what are the medications used for shock treatment

A

analgesia, sedation, antibiotics, cardiac meds (diuretics, positive inotropic, anti-arrhythmic, GI protectants

15
Q

what patients are recommended for synthetic colloids

A

hypoproteinemic patients, ones that unable to tolerate large volumes of fluid, give in conjunction with crystalloid

16
Q

what should we know about synthetic colloids

A

solution with suspension of large particles that attracts water, vascular expansion, increased colloid oncotic pressure)

17
Q

what are examples of synthetic colloids

A

dextran, hetastarch, pentastarch, voluven

18
Q

what are the adverse effects of synthetic colloids

A

coagulation, cross matching, kidney injury
