Flashcards in Cardiogenic shock in pediatric patients Deck (19):
SV x HR
definition: cardiogenic shock
heart fails as a pump to provide adequate circulation to meet the metabolic needs of the body
CO plus systemic vascular resistance (SVR)
is CO mroe strongly influenced by HR or SV? why?
children do not have as much ventricular muscle mass
what is the response to decreased CO in children?
what does it mean when kids have VT?
SV is dependent upon which three factors?
what are the effects on preload, afterload, and contractility in cardiogenic shock?
what are the effects on preload, afterload, and contractility in hypovolemic shock?
what are the general (and specific) causes of cardiogenic shock?
acquired - rheumatic fever, cardiomyopathies
non-cardiac - pneumothorax, hyperkalemia, hypocalcemia
congenital heart disease - large ventricular septal defects
what is the child's principal means of maintaining CO?
what studies / tests are done to assess and diagnose cardiogenic shock? which is most specific?
ECHOCARDIOGRAPHY (most specific)
what lab tests are done to assess and diagnose cardiogenic shock? which is most crucial?
glucose (most crucial)
what is the goal of treating cardiogenic shock?
improve oxygen delivery to all organs
neonates with ductal-dependent lesions in cardiogenic shock should be treated with what agent? why?
maintain patent ductus arteriosus
when should you use PGE1?
neonates with ductal-dependent lesions in cardiogenic shock to maintain patent ductus arteriosus
what agents can be considered early to prevent volume overload in cardiogenic shock?
inotropic agents - DA, dobutamine, EPI
which agents increase SV by reducing afterload?
