TESTE DEIN WISSEN
What is the gold standard for direct evaluation of cardiac function and volume status?
Lösung anzeigen
TESTE DEIN WISSEN
(TEE) Transesophageal Echocardiography
Lösung ausblenden
TESTE DEIN WISSEN
What is the intraoperative goal for urine output?
Lösung anzeigen
TESTE DEIN WISSEN
0.5-1 ml/kg/hr
change in urine output does not occur until 20% of blood volume is lost
Lösung ausblenden
TESTE DEIN WISSEN
What happens during the activation of hypothalamic pituitary axis?
Lösung anzeigen
TESTE DEIN WISSEN
  • cortisol release
stimulates protein catabolism, hepatic gluconegenesis and glycogenolysis, increased hepatic production and release of plasma proteins, hyperglycemia, helps tp preserve intravascular volume (energy), increased metabolic demand
  • release catecholamines
SNS effects:increased HR, SVR, and micro circulatory vasoconstriction
increase BMR and increased oxygen demand
triggers release of ADH
Lösung ausblenden
TESTE DEIN WISSEN
When does a change in BP occur in a patient that’s supine?
Lösung anzeigen
TESTE DEIN WISSEN
When 30% of blood volume is lost
Lösung ausblenden
TESTE DEIN WISSEN
What is the total body water?
Lösung anzeigen
TESTE DEIN WISSEN
60% of lean body mass
  • INTRAcellular volume 2/3 (IPP)
Potassium is primary CATION
Phosphate is primary ANION
  • EXTRAcellular volume is 1/3 (ESC)
Sodium is primary CATION
Chloride is primary ANION
Lösung ausblenden
TESTE DEIN WISSEN
What is the daily volume to maintain TBW homeostasis in the healthy adult?
Lösung anzeigen
TESTE DEIN WISSEN
25-35 ml/kg per day (approximately 2-3 liters per day)
Lösung ausblenden
TESTE DEIN WISSEN
How do you calculate the ESTIMATED FLUID DEFICIT?
Lösung anzeigen
TESTE DEIN WISSEN
Maintenance fluid required x # of NPO hours

ADMINISTER 50% during the 1st hour, 25% in the 2nd and 25% in the 3rd hour. 
Lösung ausblenden
TESTE DEIN WISSEN
What are the guidelines for replacement of SURGICAL FLUID loss?
Lösung anzeigen
TESTE DEIN WISSEN
Replacing fluid loss is based on the type of trauma:
  • superficial trauma (orofacial)-1-2ml/kg/hr
  • minimal trauma (hemiorrhaphy)-2-4ml/kg/hr
  • moderate trauma (major NONabdomnial or laparoscopic abdominal surgery) 4-6 ml/kg/hr
  • severe trauma (major open abdominal surgery)-6-8ml/kg/hr
Lösung ausblenden
TESTE DEIN WISSEN
What is the requirement for replacement of BLOOD loss?
Lösung anzeigen
TESTE DEIN WISSEN
Crystalloid is 3:1 ( 3ml fo every 1ml of blood loss)
Colliod/bloodis 1:1 (1ml for every 1 ml of blood loss)
Lösung ausblenden
TESTE DEIN WISSEN
What are some signs of HYPERvolemia?
Lösung anzeigen
TESTE DEIN WISSEN
Pitting edema, presacral edema

Later signs: tachycardia, crackles, wheezing, pulmonary edema
Lösung ausblenden
TESTE DEIN WISSEN
Tell me about sodium chloride (NS)?
Lösung anzeigen
TESTE DEIN WISSEN
  • LEAST physiologic
  • contains equal concentrations of sodium and chloride
  • can cause hyperchloremic metabolic acidosis
  • Hyperchloremia can impact renal function-decrease GFR, impair bicarbonate 
  • INCREASED salt and water retention 

Lösung ausblenden
TESTE DEIN WISSEN
Tell me about lactated ringers (LR)?
Lösung anzeigen
TESTE DEIN WISSEN
  • Contains sodium lactate as a bicarbonate substrate (buffering agent)
  • helps maintain pH
  • contains calcium-dont infuse with blood products
  • mildly hypotonic-can cause cerebral edema
  • Not recommended for large volume administration in diabetic patients
