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.
