Misc Flashcards
SIRS
-Systemic inflammatory response syndrome
-clinical state of systemic inflammation
Causes of SIRS
-Infectious
-Non-infectious (panky, polytrauma, burns, heatstroke, neoplasia, immune-mediated disease, post-op)
SIRS criteria
Diagnosis of SIRS consist of fulfilling 2 out of the following 4 criteria in dogs and 3 out of 4 criteria in cats:
(1) increased or decreased temperature
(2) tachycardia (or bradycardia in cats)
(3) tachypnea
(4) leukon abnormalities
Sepsis-2
- categorizes patients into 3 groups: sepsis, severe sepsis, septic shock based on the presence of infection, SIRS, MODS, and refractory hypotension
Sepsis-3
-Categorizes patients into 2 groups (sepsis and septic shock) based on the presence of infection with organ dysfunction, refractory hypotension, and persistently increased lactate despite appropriate resuscitation
-Selects for patients with more severe cases of sepsis and higher risk of death compared to Sepsis-2
Branched amino acids
leucine, isoleucine, valine
Gq receptors
-activates IP3, DAG
-Alpha 1, endothelin, V1, M1, M3, M5, H1
Gs receptors
Activates cAMP -> PKA
- B1
-B2
-V2
-Adenosine
-H2
-glucagon
Gi receptors
-prevents conversion to cAMP
-M2
-M4
-alpha 2
-opioids
-D2
-Somatostatin
-GABA b
Metabolic derangements seen with refeeding syndrome
Hypophosphatemia, hypomagnesemia, hypokalemia, hyponatremia, hypocalcemia, hyperglycemia, and vitamin deficiencies
Processes body uses to maintain acid-base balance
1) regulation of PCO2 by alveolar ventilation
2) buffering of acids by bicarbonate and non- bicarbonate buffers
3) changes in renal excretion of acid or base
Traditional acid base approach
Uses the Henderson - hasselbach equation for carbonic acid and uses pH, PCO2, and bicarb concentration.
PH has a direct relationship with bicarb concentration and an inverse relationship with PCO2
Purpose of anion gap
To identify the cause of a metabolic acidosis
Unmeasured anions are more abundant than unmeasured cations, the AG is essentially a marker of the amount of unmeasured cations
Measured cations
Sodium, potassium
Account for 95% total cations
Measured anions
Bicarb, chloride
Accounts for 85% total anions
Unmeasured cations
Albumin, lactate, phosphates, sulfates, ketones
Some drugs and toxins can also account for it, including methanol, salicylate, and ethylene glycol
Causes of increased ion gap metabolic acidosis
DUEL
-DKA
-Uremia
-Ethylene glycol
-Lactic acidosis
-Salicylate, Methanol (toxins)
Causes of hyperchloremic metabolic acidosis
-Renal bicarb loss
-GI bicarb loss
-NaCl administration
-Addison’s
Metabolic acidosis
Decreased pH, HCO3-, PCO2
Metabolic alkalosis
Increased pH, HCO3-, PCO2
Normal anion gap for dogs and cats
10-15 mEq/L
> 25 = acidotic
