Cheat Sheet
- Optimize cerebral perfusion pressure - Think of your brain like a delicate garden: elevating the head of the bed to about 30° encourages proper blood flow and keeps intracranial pressure from flooding the scene. This simple adjustment can make a world of difference when you're balancing oxygen delivery and pressure inside the skull. Cerebral Edema on Wikipedia
- Prevent hypoxia and hypercapnia - Low oxygen and high carbon dioxide levels are like opening floodgates for brain swelling, since they cause powerful cerebral vasodilation. Keeping oxygenation and ventilation in check helps you avoid those dangerous pressure spikes. Cerebral Edema on Wikipedia
- Pretreat before rapid sequence intubation - Using sedatives and nondepolarizing muscle relaxants before intubation is like giving your patient a calming blanket: it reduces acute ICP surges. Although IV lidocaine sounds promising, the evidence just isn't there - stick with proven sedative agents. Cerebral Edema on Wikipedia
- Use PEEP with caution - Positive end-expiratory pressure can trickle oxygen back into your lungs but, at the same time, might hamper brain venous drainage and nudge ICP upward. Apply PEEP thoughtfully and monitor intracranial dynamics closely. Cerebral Edema on Wikipedia
- Maintain CPP above 60 mm Hg - Cerebral perfusion pressure is your brain's lifeline, so keeping it above 60 mm Hg ensures cells get the nutrients they crave. Avoid hypotonic fluids and consider hypertonic saline to pull extra fluid out of swollen brain tissues. Cerebral Edema on Wikipedia
- Leverage propofol for sedation - Propofol is a multitasker: it calms the patient, drops metabolic demand, and even fights seizures, all while giving you tight control over drug levels thanks to its quick on/off action. Just watch out for potential blood pressure dips. Cerebral Edema on Wikipedia
- Choose nondepolarizing neuromuscular blockers - Agents like doxacurium and atracurium help with ventilation in brain-injured patients without the ICP spikes that succinylcholine can cause. Although data are limited, these safer options are wise picks in critical scenarios. Cerebral Edema on Wikipedia
- Prefer enteral nutrition wisely - Feeding through the gut is ideal for acute brain injury, but make sure formulas limit free water so you don't inadvertently worsen edema. Think of it as hydrating strategically rather than flooding the system. Cerebral Edema on Wikipedia
- Control hyperglycemia - High blood sugar behaves like a magnet for swelling and raises the risk of hemorrhagic transformation in stroke patients. Target a blood glucose below 180 mg/dL to keep your brain's environment as stable as possible. Cerebral Edema on Wikipedia
- Use hypertonic saline over mannitol when needed - Hypertonic saline not only pulls fluid out of the brain to lower ICP but also helps maintain blood volume, making it a hero in cases of hypovolemia or low sodium. It's often the preferred osmotic agent in tricky scenarios. Cerebral Edema on Wikipedia
