Questions B Flashcards
AAA risk factors and infections
AAA can be caused by fungal infections or syphilis
RF. Smoker, age, male, atherosclerosis, family history
Treatment for muscle rigidity after opiates
Muscle relaxants, BZD, naloxone
Optimal CO in CPR
25-30%
V.A. effects on Breath rate, inspiration and expiration
Increase BR, shortening inspiration and expiration
Factors that increase the magnitude of opioid-induced respiratory depression
Dose, sleep, age, VA, renal insufficiency, pain, resp acidosis
Neuromuscular blocking effect of VA
D > S > I > H
Bupicaine charac
Less cardiotoxic than lido, more than ropi (more inotropic effect)
More cardiotoxic in pregnant woman
Eye damage
Anterior ischemic Optic N.
1. AION Optic disc swelling, hemorrhages
2. CRAO Cherry red macula
3. Cortical blindness. Normal light reflex and absent nystagmus
4. BRAO. Retinal whitening + edema.
Twin twin transfusion syndrome
Most common complication PROM
Can cause kidney failure in donor twin.
After the first trimester
No synergistic effect in
K + P
K + BZD
a2 + P
Sevo + P
Effect of VA in CO
Halothane decreases CO
AKI stages
Stage I < 0.5 mg/kg/h >6 hours
Stage II < 0.5 mg/kg/h > 12 h
Stage III < 0.3 for more than 12h
In recovery room
Check vital signs every 15 min
Most common compl. PONV
Flagyl can cause residual neuromuscular blockage
Test more sensitive for pneumothorax
CT = US
Risk Factors for Development of
Postoperative Acute Kidney Injury
Preoperative Factors
□ Preoperative renal dysfunction
□ Increasing age
□ Heart disease (ischemic or congestive)
□ Smoking
□ Diabetes mellitus
□ American Society of Anesthesiologists Physical Status classification 4 or 5
Intraoperative Factors
□ Emergency surgery or intraperitoneal, intrathoracic, suprainguinal vascular surgeries
□ Erythrocyte transfusion
□ Inotrope use
□ Aortic cross-clamp time
□ Cardiopulmonary bypass: furosemide use, urine output, need for a new pump run
Postoperative Factors
□ Erythrocyte transfusion
□ Vasoconstrictor use
□ Diuretic use
□ Antiarrhythmic drug use
