    Study Notes

    AAA Symptoms

    • Dull, vague pain in abdomen, back, or flank
    • Can be acute and severe in ruptured AAA
    • Sensation of a pulsatile mass in abdomen
    • Hypotension (often manifesting as syncope)
    • Commonly occurring in ruptured AAA
    • Associated complications: diminished femoral pulses, "blue toe" syndrome, duodenal obstruction (vomiting, weight loss), vertebral body erosion (severe back pain)
    • Best place to rupture is in the back/posterior because it can tamponade and hold pressure
    • Grey Turner's sign: flank ecchymosis
    • Severe back pain

    AAA Treatment

    • Medical management: control hypertension, stop smoking, ACE inhibitors/statins may be beneficial
    • Monitoring: ultrasound/CT scans every 6-12 months (smaller aneurysms 4.0-5.4), every 3 years (smaller than 4.0)
    • Open repair (more involved): monitor kidneys, urine output, pedal pulses, and extremity movement to ensure proper function
    • Maintain normal conditions to avoid graft busting or clotting

    Hemodynamic Monitoring

    • Catheter markings: thin line = 10cm, thick line = 50cm
    • RV waveform: normal value 15-25/0-8mmHg; catheter in RV may cause ventricular ectopy, swan tip may drift from PA to RV
    • PA waveform: normal value 15-25/8-15mmHg; dicrotic notch represents PV closure; PAD approximates PAWP (LVEDP)
    • RA waveform: normal value 0-8mmHg
    • PAWP waveform: normal value 8-12mmHg; balloon floats and wedges in pulmonary artery; PAWP = LAP = LVEDP; wedging can cause capillary rupture

    CO, CI, SV, SVR, and PVR

    • CO (cardiac output): normal 4-8 liters, heart rate x stroke volume
    • CI (cardiac index): normal 2.5-4.5 liters
    • SV (stroke volume): normal 50-100 ml/beat
    • SVR (systemic vascular resistance): normal 800-1200
    • PVR (pulmonary vascular resistance): normal 50-250

    Cerebral Perfusion Pressure (CPP)

    • Pressure needed to ensure blood flow to the brain.
    • Calculated as CPP = MAP - ICP (whichever is higher)
    • Normal CPP is 60-100.
    • Factors influencing cerebral blood flow include trauma and bleeding

    Intracranial Pressure (ICP)

    • Factors influencing ICP: arterial pressure, venous pressure, posture
    • Normal ICP is less than 15 mmHg.
    • Increased ICP (greater than 20) necessitates intervention to prevent brain infarction.
    • Neuro assessments are crucial, and the external transducer should be leveled accurately at the foramen of Monro/tragus at the ear.
    • Keep the patient at a 20-30-degree angle to help drain cerebrospinal fluid, done slowly. 30 ml cerebrospinal fluid an hour drain, can be slow or fast.
    • Signs of increased ICP include: decerebrate or decorticate posturing, headache (worse in the morning), vomiting, changes in consciousness (from calm to agitated to comatose), Cushing triad (systolic hypertension, bradycardia, irregular respirations).
    • Therapeutic measures- Mannitol (osmitrol) which is osmotic and should prevent pulmonary edema. and decrease cerebral spinal fluid production.
    • Drug therapy- antipyretics, cooling blankets (prevent shivering), barbiturates, when necessary. Antiseizure medications

    ICP Treatment

    • Manage contributing factors (e.g., hypertension, fever)
    • Drain cerebrospinal fluid (e.g., lumbar or ventricular)
    • Medications: osmotic diuretics (e.g., mannitol), barbiturates
    • Monitor ICP closely

    Other important information

    • Hypertonic saline (3% saline) or normal saline may be used in cases of brain swelling.
    • Monitor blood pressure, electrolytes, and glucose levels.
    • Avoid alcohol, aspirin, acetaminophen, and NSAIDs in patients with cirrhosis.
