ACE Flashcards
Most common complication of OB paracervical block
-fetal bradycardia
U/S PNX
lung point
Intra-aortic ballon pump
- he primary purpose of IABP therapy is to improve myocardial perfusion during diastole by improving coronary blood flow. It also reduces left ventricular afterload, thus decreasing left ventricular work.
- The most accurate way to correctly time IABP counterpulsation is to initiate inflation immediately as the dicrotic notch is detected. Deflation of the IABP balloon should take place just before the systolic upstroke
- helium in balloon
Peds, % blood loss before hypotension
40%
Shortest half life of benzos (versed, lorazepam, diazepam, alprazolam)
versed
Methylphenidate perioperative concerns
increased cardiovascular instability, altered anesthesia requirements, and lowering of the seizure threshold. Methylphenidate use is associated with an increased minimum alveolar concentration (MAC) and thus a decreased sensitivity to volatile anesthetics. Time to emergence from general anesthesia is not increased in patients taking methylphenidate
Carcinoid heart disease
Carcinoid heart disease typically produces tricuspid regurgitation and mixed pulmonic stenosis and regurgitation, resulting in right heart failure.
OI associations
-platelet dysfunction, easy trauma, pectus excavatum, heat intolerance, increases thyroid hormone
Dementia drugs interactions
-Anticholinesterase medications are also frequently used in the treatment of dementia (eg, donepezil). These medications may prolong paralysis from succinylcholine and impact nondepolarizing muscle relaxants by decreasing or reversing their effects
Most predictve on unsuccessful mask
-neck radiation changes
Fractional flow reserve
< .8 likely to improve with PCI or stent
Pregnancy s/p renal transplant
However, some complications of pregnancy are higher in transplant recipients, such as preeclampsia (27.0% vs 3.8%) and gestational diabetes (8% vs 3.9%). Also higher are the rates of cesarean delivery (56.9% vs 31.9%) and preterm delivery (45.6% vs 12.5%
presedex context sensitive halflife for 40 yo
50 minutes
post ROSC hypothermia
32°C to 34°C and 34°C to 36°C
MH susceptibility
There is a wide range of disorders associated with mutations in the RYR1 gene (eg, central core disease, King–Denborough syndrome, periodic paralysis, and idiopathic hyperCKemia).
Stellate ganglion block
- In 80% of patients, the stellate ganglion is formed by the inferior cervical and the first thoracic ganglion. The anterior approach is most commonly used for SGB
- Left-sided SGB has been noted to be more effective at managing ventricular arrhythmias. If left SGB fails, a right SGB can be added, but this should be restricted to intubated patients, as bilateral phrenic nerve paralysis is possible
- LA injected anterior to longus colli muscle
TIPS procedure
shunt between hepatic vein and portal vein
Aortic coarctation
headache, epistaxis, lower extremity claudication, and hypertension. Upper extremity systolic hypertension (with normal diastolic pressure) and lower extremity hypotension are also common. These individuals exhibit extensive collateral circulation
cancer drugs that interact with pseudochilinesterase
nitrogen mustards
eg, mechlorethamine, cyclophosphamide, melphalan, and chlorambucil
treatment for heparin resistance
administration of recombinant human antithrombin, additional heparin, or fresh frozen plasma (FFP)
thorasic scoliosis PFTs
- follow restrictive pattern
- decrease in FVC
PONV acupuncture
Pericardium-6
- 4 cm proximal to the distal wrist crease, between the palmaris longus and flexor carpi radialis tendons
Parkinsons and PONV
Haloperidol, metoclopramide, and promethazine are all dopamine antagonists and have proved efficacious in treating PONV. However, dopamine antagonists may exacerbate symptoms in patients with Parkinson disease and should therefore be avoided in such patients.
cerebral edema in tumor
- Vasogenic cerebral edema occurs when tight endothelial junctions of the blood–brain barrier are compromised, such as with tumor growth
- Intravenous steroids, such as dexamethasone, selectively target vasogenic cerebral edema by stabilizing the blood–brain barrier
