Q

MGMT of airway/mechanical ventilation in burn patients

A

RSI unless suspicion of airway obstruction (if signs of obstruction, awake intubation), succ is contraindicated if burn is > 5 days post-burn, avoid barotrauma: limit plateau pressure to 35 mmHg, PEEP can be helpful,

4 classes; class I: major effects on fast Na channels, II: beta-adrenergic antagonists (depress SA node), III: prolong repolarization and refractory period duration (acts on K+ channels), IV: calcium channel blockers

130
Q

procainamide: ventricular dysrhythias and Supraventricualr dysrhythmias,

131

A

lidocaine: suppress dysrhythmias from enhanced automaticity such as VT, and suppress SA/AV node

example of class IC agents: profoundly slow depolarization and conduction, associated with prodysrhythmias, creation of new ventricular dysrhythmias, only seen in the US

A

flecainide, propafenone,

133
Q

Example of Class II agent: beta adrenergic blockers - suppress SA node and slow conduction through AV node; B1 > B2 is more cardioselective

hypotension, bradycardia, heart failure

138
Q

long-term effects of amiodarone

A

corneal deposits, photosensitivity, gastrointestinal intolerance

139
Q

digoxin MOA

A

inhibits Na-K exchange pump –> increases Na in the cell, resulting in increased intracellular Ca –> +inotropic effects, prodysrhythmic effects , slows AV node via lengthening of refractory period

140
Q

SE of digoxin

A

GI, fatigue, drowsiness, visual color disturbances (van gogh), headache, depression, apathy; psychosis, HB, increased ectopy, vTach, MAT, junctional rhythm

141
Q

TTP sx (mnemonic)

A

“FAT RN” - fever, anemia, thrombocytopenia, renal, neuro symptoms

142
Q

DDX to consider with ?TTP

A

HUS (hemolytic uremic syndrome), ITP, DIC

143
Q

difference between HUS and TTP

A

TTP has more CNS involvement, HUS has renal involvement, HUS has often diarrhea

144
Q

ITP vs. TTP

A

ITP pts are not very sick and have normal CBC; TTP are very sick with SCHISTOCYTES

145
Q

DIC vs TTP

A

DIC - multiple sites of bleeding, elevated INR, PTT and d-dimer vs. TTP don’t have overt bleeding, and mildly elevated INR, PTT and D-dimer

146
Q

MGMT of TTP

A

plasma exchange indicated in MAHA (schistocytes, elevated LDH, elevated indirect bili)

147
Q

Pathophysiology of TTP

A

endothelial injury with platelet rich thrombi causing MAHA and thrombocytopenia; vWF made in endothelial cells and assembled in large multimers which are cut by ADAM TS13 into smaller unit; ADAMS13 does not function correctly and these vWF multilers collect and accumulate, which results in platelet aggregation forming clots, and also theres multimers cleave RBCs intravascularly

148
Q

triggers of TTP (inherited or acquired)

A

HIV, malignancy, pregnancy, medication, organ transplant, chemotherapy, pancreatitis, autoimmune disease, idiopathic

149
Q

seizures, coma, often transient

150
Q

Plt cut off for TTP

non-immune hemolysis with schistcytes from RBC fragmentation, elevated LDH, low haptoglobin, high indirect bilirubin, LDH elevated

152
Q

Other key sx for TTP

A

fever, renal disease (UA with mild protein, hematuria), GI symptoms, splenomegaly and jaundince, cardiac sx (MI, arrhythmia, shock, heart failure)

153
