1

what is the goal of shock treatment

restoration of oxygen delivery to the tissues

2

what are the clinical signs of dyspnea and hypoxia

cyanosis, tachycardia, tachypnea, melena, anxiety

3

what does oxygen therapy depend on

duration, demeanor of patient, equipment avail.

4

what are the methods of O2 admin

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

5

what is the fluid therapy for shock syndrome

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

6

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

isotonic cystalloids, hypertonic saline, synthetic colloids

7

what should we know about isotonic crystalloids

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

8

what are the benefits of isotonic cystalloids

inexpensive, long track record of success, ability of redistribution

9

what are the advert effects of isotonic fluids

rate of infusion, predisposition of fluid overload

10

what should we know about hypertonic crystalloids

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

11

what are the benefits of hypertonic crystalloids

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

12

what are the adverse effects of hypertonic crystalloids

hypernatremia, hyperchloremia, metabolic acidosis, vasodilation and cardiovascular collapse

13

which patients should we not use hypertonic crystalloids in

dehydrated patients

14

what are the medications used for shock treatment

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

15

what patients are recommended for synthetic colloids

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

16

what should we know about synthetic colloids

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

17

what are examples of synthetic colloids

dextran, hetastarch, pentastarch, voluven

18

what are the adverse effects of synthetic colloids

coagulation, cross matching, kidney injury
