Anesthesia Flashcards
preoperative anxiety relieved by
good anesthesiologist
H2 antagonists prevent aspiration pneumonitis
increasing pH of gastric cntents
most common complication after extubation
laryngospasm
spinal anesthesia site
between arachnoid and pia mater of the cord
spinal HA characteristic
goes away when the patient lies down
most common cause of hypotension postanesthesia
hypovolemia
most effective way to preserve myocardial perfusion in ischemic heart
HR as low as possible
MVP at risk of
fatal arrhythmia
quits smoking 3 days prior to surgery
improved O2 delivery to tissues
T1DM blood glucose control decreases
wound infection
greatest concern in hyperthyroidism
stress may lead to severe arrhythmia and hypertension
increases sickling and vascular occlusion
hypovolemia
central nervous system excitement after injection
IV injection
most potent opioid
sufentanil
narcotic causes least respiratory depression
all are alike
most likely cause anterograde amnesia
midazolam
induction agent permits earliest return to normal function
propofol
reliable monitor of adequacy of ventilation
capnography
shows ischemic episodes during anesthesia
II and V5
patient controlled analgesia advantage
patient does not experience wide swings in level of pain
breath sounds, tracheostoma
place ET tube in tracheostoma and begin mechanical ventilation
etiology of respiratory distress
regurgitation and aspiration of gastric tube infused tube feedings
best method of securing airway when anterior neck injury, hoarseness
tracheostomy
bowel resection post op increased HR and low BP
normal saline infusion
CPR pH of 7.25
hyperventilate the patient
fetal heart deceleration associated
fetal head compressions or umbilical cord compressions
sign of cyanide toxicity during nitroprusside therapy
increased mixed venous PO2
reaction to ester anesthetics, most likely to provoke allergic or anaphylactic reaction
tetracaine
lorazepam in patient with liver transplant
conjugated extrahepatically
sevoflurane rapid recovery
low blood:gas partition coefficient
pre-existing conditions predisposes to new onset third degree heart block
LBBB
early development of polyuria, hypotension, low sodium in urine
SIADH
elongated crescent shaped erythrocytes
volume load with crystalloid
most likely cause respiratory distress
residual muscle paralysis
difficult to intubate
short thyromental distance and prominent incisors
ASA physical status classification is matched to correct patient description-ASA IV
severe systemic disease that limits activity and is a constant threat to life
improve preoperative respiratory function
plasmapharesis
most common upper extremity peripheral nerve injury during general anesthesia
ulnar
can pass through BBB
atropine
vasoconstriction least likely following sympathomimetic
isoprotenerol
most important factor determining spread of local anesthetic after spinal injection
total dose of injected drug
best describes fetal pulmonary vascualr resistance
high compared to systemic vascular resistance
most characteristic of spinal anestheric
has an almost sympathetic blockage before a motor block
true of spinal anesthetic placement procedure
intubation equipment should be readily available
pin point pupils and responds to painful stimulation
naloxone
incorrect statement
morphine is 10x more potent than fentanyl
most characteristic of epidural anesthetic
total spinal could occur with an epidural if you puncture the dura
