What is oncotic pressure?
A CXR of a correctly placed central line shows the tip of the catheter terminating in this structure
What is the SVC?
A modest rise in this ion after torniquet deflation can increase the risk of cardiac arrhythmias
What is potassium?
The initial drop in core temperature under general anesthesia is predominantly due to this mechanism
What is redistribution?
Influx of this cation at the nerve terminal signals the release of Ach molecules into the synaptic cleft
What is calcium?
Pulse oximetry calculates the difference between light absorbed at these two wavelengths
What is 660nm (red) and 940nm (infrared)?
This intervention for acute coronary syndrome allows elective noncardiac surgery to proceed after 30 days
What is a bare metal stent?
During CO2 insufflation of the abdomen, patients may experience hypotension due to the impact of increased intrabdominal pressure on this cardiovascular element
What is preload?
Malignant hyperthermia demonstrates this pattern of genetic inheritance
What is autosomal dominant inheritance?
Binding of acetylcholine to the acetylcholine receptor causes influx of this ion into the post synaptic cleft to generate the muscle action potential leading to muscle contraction
What is sodium?
This acid base disturbance can be caused by large volume resuscitation with normal saline
What is hyperchloremic metabolic acidosis?
This is the amount of time you would ideally wait to proceed with elective non-cardiac surgery after a patient has had a myocardial infarction without intervention
What is 30 days?
These two acid-base derangements are most likely to occur following tourniquet deflation
What is metabolic acidosis (lactate) and respiratory acidosis (hypercarbia)?
Hypothermia in the perioperative period can result in coagulopathies because of impairment of this part of the coagulation cascade
What is platelet aggregation
A train of four ratio of 0.9 measured at this muscle is considered the standard for adequate recovery of neuromuscular blockade
What is the adductor pollicis muscle?
During an awake fiberoptic intubation, a patient is topicalized with benzocaine. 10 minutes later before any sedation is given, her pulse oximeter reads 85%. You believe that the patient’s PaO2 will be normal, and she likely has this disorder
What is Methemoglobinemia?
In this reflex, receptors located at the cavoatrial junction increase heart rate after sensing a rise in CVP
What is the Bainbridge reflex?
Bradycardia caused by increased vagal nerve stimulation is common during insufflation and is due to the stretching of this structure
What is the peritoneum?
This test represents the gold standard for diagnosing malignant hyperthermia
What is the caffeine-halothane contracture test?
Even with 4 qualitative twitches, up to this percentage of receptors can still be blocked by a neuromuscular blocking agent
What is 30%?
Blockade of these sympathetic fibers at T5-T12 cause increase in gastrointestinal blood flow and gut motility
What are Splanchnic sympathetic fibers?
Insertion of a central line on the left side has the highest incidence of damaging this structure which would cause a fluid collection high in triglycerides
What is the thoracic duct?
Increased carbon dioxide levels during laparoscopy can cause a significant increase in this cardiovascular numeric, increasing the work of the right ventricle
What is PVR?
