OR Monitors/Equipments
The biggest contributor to heat loss in the operative period.
Conduction, Convection, Radiation, Evaporation
Radiation
Minimum fasting period for kid who ate cereal with cow milk
6 hours
This disease causes resistance to succinylcholine and sensitivity to nondepolarizing neuromuscular blocking agents.
Myasthenia gravis
Most likely blood product to cause sepsis.
Platelets
Made by the liver, this enzyme metabolizes medications like succinylcholine, mivacurium, ester type local anesthetics, cocaine, and heroin
Pseudocholinesterase
The most appropriate lead for monitoring atrial dysrhythmias due to P-wave size.
Lead II (displays the greatest P wave voltage)
The leading cause of death in children over age 1 in the United States.
Trauma
This common patient position in the OR can cause a patient to develop foot drop.
Lithotomy with stirrups.
The pathology where 2-3 wks following spinal cord injury above T5-6, stimulation below level of injury leads to uninhibited sympathetic stimulation.
Autonomic hyperreflexia
The average rise in potassium with succinylcholine.
0.5 mEq/L
The Mapleson breathing circuit that allows for more rapid changes in inspired gas concentration compared to the circle system. It is also the most efficient for Controlled ventilation.
Bain/mapleson D Circuit
The deceleration type seen 10 to 30 secs after contraction indicating uteroplacental insufficiency/hypoxemia
Early deceleration – occurs with contraction, fetal head compression
Late deceleration – 10 to 30 secs after contraction, uteroplacental insufficiency/hypoxemia
Variable deceleration – umbilical cord compression (tolerable if transient)
This cranial nerve provides the majority of pharyngeal sensory innervation and also carries the afferent limb of the gag reflex.
Glossopharyngeal nerve (cranial nerve IX)
Most common adverse effect associated with a celiac plexus block (T5-12).
Diarrhea
This block is done for pain relating to abdominal cancers. Complications include bleeding, retroperitoneal hematoma, chylothorax, perforation of nearby structures, pneumothorax, diarrhea.
Considered a colloid, this intravascular volume expander reduces availability of glycoprotein IIb-IIIa on platelets leading to platelet dysfunction and increases renal injury.
Hetastarch
Two drugs. One with falsely low EEG activity while the other falsely high EEG activity.
Dexmedetomidine/Ketamine
"steeple sign" seen on CXR.
Croup aka laryngotracheobronchitis caused by virus with sypmtoms of “barking” cough, stridor, hoarse voice.
The active metabolite in Morphine causing neuroexcitability.
Morphine-3-Glucuronide (M3G)
Daily Double
Shivakeerthy Ubranimath
Dextromethorphan, ketamine, phencyclidine, nitrous oxide, methadone, and magnesium sulfate target this common receptor.
NMDA
A desflurane vaporizer calibrated for use at sea level is being used at 18,000 feet (barometric pressure is 380 mmHg). What is the MAC if the concentration dial is set to 6%?
0.5
To achieve 1 MAC at 0.5 atm, the desflurane dial would need to be turned to 12%.
During neonatal resuscitation, positive pressure ventilation is indicated if the neonate’s heart rate drops below 100 bpm. However, Chest compressions should be started at this different heart rate.
Glasgow Coma scale – eyes open spontaneously, confused conversation but able to answer questions, withdraws from pain.
E4 V4 M4 = 12
The cause of succinylcholine-induced hyperkalemia in muscular dystrophy is due to ___.
Rhabdomyolysis.
Medication that inhibits 11-B hydroxylase.
Etomidate which decreases cortisol and aldosterone.
