27
CPK is released into the bloodstream when
muscles are damaged
- MI
28
Inflammation activates
macrophages, neutrophils, platelets to the area which causes the endothelium (lining of the vessels) to release cytokines which activate the inflammatory pathways
29
Neutrophils
50-70%
- first responders
- fight injury/infection
30
Bands
< 10%
- Babies
- immature neutrophils
- if increase, then very sick and has been sick for a while
31
Eosinophils
1-5%
- parasite fighters
32
Basophils
1%
- non-specific immune response (asthma)
- release histamines
33
Lymphocytes
20-40%
- B and T cells
- humoral immunity (antibodies against specific antigens)
34
Monocytes
2-8%
- migrate to tissues and clean up dead cells
35
Mast Cells
- immune cells
- connective tissue cells that contain histamine
36
If bands are elevated in a serum blood draw, we call this
a shift to the left
- infection
- inflammation
- release WBCs before they are fully mature
37
Inflammation Patho
1) Tissue injury
2)
- Capillary widening = increased blood flow
- Increased permeability = fluid release into tissues
- attraction of leukocytes = extravasation of leukocytes to site of injury
- systemic reaction = fever and proliferation of leukocytes
3) Heat, redness, swelling, tenderness, and pain
38
SIRS patho
1) Chemical messengers release widespread histamine
2) Widespread separation of endothelial cells = vasodilation
3) Increased blood flow = need for greater CO = TACHYCARDIA
4) increased need for O2 = TACHYPNEA = HYPOCAPNIA
5) LEUKOCYTOSIS initially and then as the WBCs are decreased = LEUKOPENIA = increased production = increased immature WBCs in blood (bands) = shift to the left
6) immune response stimulated = “thermostat” of hypothalamus altered = HYPERTHERMIA(Proper response) or HYPOTHERMIA (Improper response)
39
What type of concepts happen in SIRS?
Oxygenation - disrupted gas exchange
Perfusion - vasoconstriction/dilation = Tachycardia/Tachypnea/Hypocapnia
Immunity - leukocytosis/leukopenia
Thermoregulation = high or low
40
SIRS
Systemic inflammatory response syndrome
41
SIRS caused by
stressors that are either infectious or noninfectious that cause acute inflammation
42

Organ Dysfunction
91
Septic shock is the stage of
sepsis when MODS and organ failure are evident AND poor clotting with uncontrolled bleeding can occur.
- severe hypovolemic shock and hypodynamic cardiac function present
**sepsis on steroids**
92
Massive vasodilation
Increased vessel diameter & permeability
Decreased systemic vascular resistance (SVR)
Decrease in blood pressure
Initially increased Cardiac Output (CO) to compensate for decreased SVR
Continual feedback causes decreased CO
WARM skin initially but as progresses will become COOL
93
Damage to vessels systemically causing
coagulation factors to clot
Eventually clotting factors used up
Causing disseminated intravascular coagulopathy (DIC)
94
Hypoperfusion
= Organs not receiving oxygen and an anaerobic metabolism occurs
Lactic acid produced and levels begin to rise rapidly
95
Respiratory blood vessels damaged cause
Acute respiratory distress syndrome (ARDS)
Severe hypoxemia
Need to be mechanically ventilated
96
What happens to the body when septic shock occurs?
Increased WBC to area all throughout the body
Vessels increase in diameter due to the increased WBCs and other molecules called to the intravascular space
Vessels become more permeable and begin to leak fluid into the interstitial tissue space (decreased systemic vascular resistance SVR) which decreases BP
This increased fluid cause issues with oxygen transport to tissues
The endotoxins from the WBC damage the blood vessels
Coagulation cascade starts and begins to try to clot to repair the blood vessel damage
Clots can break off in the blood stream (what would happen?)
When we run out of clotting factors, the patient begins to bleed everywhere which is DIC
Cardiac output initially increases to try to compensate for the drop in blood pressure, but eventually due to lack of oxygen it will also lose the ability to compensate so CO decreases
97
S/S resemble the late stage of
hypovolemic shock

Pain in legs or extremities, mixed temperatures let me know = DVT
118
Prior to transfusion what should the nurse do
Verify the order.
Obtain or review patient **signed consent** form (Plasma, platelets, cryo, RBC)
Physician tells them about it
Witness signature
119
Set-up for Blood Transfusion
Use blood filter tubing and prime above the filter with 0.9% NS through all tubing.
Only use NS to prime and clean line with all blood products.
Fluids containing glucose are not compatible with red blood cells and cause the RBCs to clump.
Crystalloid or colloid solutions that contain calcium should never be administered concurrently with any blood product as calcium revers the anticoagulant citrate causing RBCs to clot.
120
What should the nurse monitor during the transfusion?
Monitor patients closely when you start blood products.
Vital signs should be done prior to transfusion, 15 mins after start, and at the completion
Average duration of infusion of blood products:
RBC 1.5-3 hours
Platelets 30-60 mins as tolerated
FFP 30-90 mins
Cryoprecipitate 30 mins or less
Maximum infusion time is 4 hours
Change tubing every 4 hours
DOCUMENT
Vital signs (pre, 15 mins, and completion)
Start and stop time of infusion
Volume infused
Evidence of transfusion reaction or suspected reaction or no evidence of reaction
121
NEVER EVER SHOULD THESE BE DONE WITH BLOOD OR BLOOD PRODUCTS:
Attempt to manipulate the temperature of the unit by running under warm water or putting it in the microwave.
Contact the blood bank if it needs to warmed
Store blood components in an unmonitored refrigerator (ex: staff or patient refrigerators)
Add medications to the blood bag or line or piggy back any medications or other products
This could hemolyze or clot the blood
122
If they have reactions, then
stop and disconnect tubing and notify someone
123
Plasma
Filtered portion that provides volume, coagulation factors and other proteins
124
Platelets
Small fragments (thrombocytes) that control bleeding

- no homeostasis w/o intervention
129
Most common trigger for MODS

Mechanical Ventilation
132
1st organ initiating MODS cascade
Respiratory - Tachypnea
133
MODS: Pulmonary Dysfunction PATHO
Hypoxemia develops causing an increased drive for ventilation.
The lungs are stiff due to the inflammation in the alveoli.
Inflammation in the alveoli starts when there is reduced blood flow to the lungs, histamine is released which increases the permeability of the alveoli, and fluid shifts into the interstitial space.
This permeability allows proteins and fluids to leak out which increases the osmotic pressure and causes pulmonary edema.
As the fluid builds up, there is decreased space for O2 to exchange because of the damaged alveolocapillary membrane, but CO2 can cross the membrane.
Not having enough oxygen in the alveoli, leads to hypoperfusion of other organs, increasing the lactate level which is a byproduct of anaerobic metabolism due to low levels of oxygen in the tissues.
134
MODS: Pulmonary Dysfunction Dx
Bilateral infiltrates on chest Xray
ABG: Respiratory alkalosis
Hypocapnia
Hypoxemia
135
MODS: Pulmonary Dysfunction mgmt

Vasodilation causes hypotension:
Mean Arterial Pressure (MAP) <75 mm Hg
Low Systemic vascular resistance (SVR)
Tachycardia causing increased cardiac output and stroke volume
Myocardial depression happens when systolic and diastolic dysfunction occurs affecting both sides of the heart.
Right side gas exchange issues.
Left side perfusion issues all related to the vasodilation due to inflammation.
139

Agitation
Lethargy
Seizures
No cough/gag reflex
Slow or no pupil response
Pupils mid-position and dilated (4-9 mm)
GCS <8 (Coma)
142
MODS: NEURO Dysfunction PATHO
Both inflammatory and non-inflammatory processes cause significant alterations in the brain.
There is impaired cerebral perfusion from prolonged inflammation, severe hypoxemia, and persistent hyperglycemia.
It is the pro inflammatory mediators that relay the message to begin the inflammatory process which disrupts the microcirculatory system and compromises cerebral perfusion.
If left untreated, may result in encephalopathy or acute cerebrovascular lesions.
143
MODS: NEURO Dysfunction MGMT
Control the factors that affect the brain:
Thermoregulation
Glucose control
Hemodynamic regulation (blood pressure and oxygenation)
Adjusting the environment – low noise and lights to decrease stimulation
144

diuretics causing dehydration
steroids altering the serotonin activity
145
MODS: RENAL Dysfunction S/S
Oliguria leading to possible anuria
Fluid retention
Urine output < 0.5 mL/kg/hr
Hyperkalemia >5.5
Hematuria
Proteinuria
Creatinine >1.2
146
MODS: RENAL Dysfunction PATHO
Decreased perfusion to the kidneys due to gas exchange and perfusion issues activates the renin-angiotensin system.
Renin forms angiotensin I which is then converted to the vasopressor angiotensin II.
AGII raises low blood pressure by increasing peripheral vasoconstriction and stimulating aldosterone secretion.
Aldosterone promotes the reabsorption of water and sodium to correct the fluid deficit and inadequate blood flow causing renal ischemia.
The body is trying to protect itself from something that it has caused as a result of the original infarct or injury.
147
MODS: RENAL Dysfunction MGMT
Monitor urine output - >0.5 mL/kg/hr.
Monitor labs – creatinine elevations

>82 mcg/dL Females
>94 mcg/dL Males
Hypoalbuminemia <2 g/dL
Elevated AST and ALT
Hepatic encephalopathy
150
MODS: LIVER Dysfunction PATHO
Due to widespread organ hypoperfusion, the liver is unable to transport bile acids and bilirubin to the hepatic canaliculi, which causes cholestasis.
Lactate is not able to be cleared through the liver.
Protein synthesis is also reduced (specially albumin) which causes hypoalbuminemia which the body loses the oncotic pull into the vascular system and widespread edema can occur.
The liver cannot produce glucose which can cause hypoglycemia.
151
MODS: LIVER Dysfunction TX
Lactulose for hyperammonemia
Blood transfusions:
Albumin
Packed RBCs
Clotting factors
UV therapy
152
MODS: GI Dysfunction S/S
Abdominal pain
Distention
Hypoactive bowel sounds
No bowel sounds
Tarry stool
Bright red stool
Peristalsis leading to ileus
Permeability of GI tract
Bacterial translocation
153
MODS: GI Dysfunction PATHO
In the early stages of SIRS and MODS, blood is shunted away from the GI mucosa, making it highly vulnerable to ischemic injury.
Mucosal ischemia leads to a breakdown of this normally protective mucosal barrier.
Hypoperfusion decreases peristalsis and eventually causes paralytic ileus.
This increases the risk for ulceration, GI bleeding, and bacterial movement from the GI tract into circulation.
The gut has bacteria that is supposed to help us like low levels of Clostridium difficile and E. Coli.
If they move outside of the intestines, it has severe consequences throughout the body.
154
MODS: GI Dysfunction MGMT
Monitor for abdominal distention, peristalsis, or ileus.

Lethargic, pallor, hungry
Decreased wound healing
- CLEAR URINE
180 BLOOD SUGAR IS OKAY IN SEPSIS DUE TO STRESS
157
MODS: ENDOCRINE Dysfunction PATHO
The adrenal glands and the pancreas are two that play a role in endocrine regulation.
When there is inflammation or stress on the body, the hypothalamus signals the production of hormones such as glucocorticoids (anti-inflammatory and controls metabolism) and catecholamines (ex: dopamine and epinephrine; stimulates the heart, raises blood pressure) and both are regulated from adrenal glands.
The pancreas secretes insulin, amylase, and lipase. These are responsible for controlling glucose needs in the body.
