For low flux membranes, drugs with a molecular cialis side effects testicular pain weight less than 1000 da are removed. With high flux membranes that have larger pore sizes, drugs in the range of 10,000 to 20,000 da can be removed by diffusion of the molecules from the blood and into the dialysis solution. With hemofiltration, larger molecules are removed up to the molecular weight cutoff of the hemofilters, usually about 40,000 da. In additional to molecular weight, three additional characteristics of a drug govern removal during dialysis. Percentage of drug eliminated by the kidney, volume of distribution, and protein binding. For example, removal during crrt is greater when renal clearance accounts for 30% or more of total body clearance of the drug, volume of distribution is less than 1 l/kg, and protein binding is less than 50% because dialysis cannot remove protein-bound drugs. 49 other factors that affect drug clearance include type of rrt (ie, ihd, cvvh, cvvhd). Characteristics of the dialysis membrane. And blood, ultrafiltrate, and dialysis flow rates. In general, drug removal is greatest with cvvhdf, followed by cvvh and then ihd. 50 drug information references provide drug dosing recommendations in ihd and crrt. However, they must be interpreted cautiously due to the variability in dialysis techniques used.

Many di erent agents exist to manage acute elevations in arterial blood pressure. A comprehensive review is beyond the scope o this chapter. All these agents can adequately lower blood pressure, but an understanding o how they do so is particularly relevant in brain-injured patients, as their mechanisms vary signi cantly and have implications on cerebral physiology. O en the goal in neurologic disease is to prevent or limit bleeding, as in patients with ischemic strokes, aneurysmal sah, and intraparenchymal hemorrhage. Which antihypertensives are most commonly used in the nicu, and how do they di er?. Wo o the most commonly used medications are labetalol and nicardipine, although others such as esmolol and enaloprilat may be used as well. Labetalol acts primarily via nonselective beta blockade has some alpha1 blocking properties commonly administered in intermittent bolus dosing, although can be given as a continuous in usion maintains cardiac output and peripheral per usion preserves cerebral blood ow and autoregulation 72 t is makes it an attractive antihypertensive in patients with neurologic injuries. Has its maximum e ect 5–15 minutes a er injection with a hal -li e o 2–4 hours, although this hal -li e is airly variable between di erent individuals nicardipine a calcium channel blocker that is highly selective or peripheral receptors decreases vascular resistance without signi cant e ects on heart rate must be given via continuous in usion peak e ect is reached in 100 seconds hal -li e o its action is 3–7 minutes ewer dosing adjustments and additional agents than labetalol in a nicu population.74 in sah patients speci cally, it has been shown to reach target blood pressures aster, ail less o en, and maintain blood pressure within goal a greater percentage o the time.75 studies in general icus have also supported a aster attainment o blood pressure goals with nicardipine,76,77 and, in some cases, less adverse events, particularly hypotension or bradycardia.76 i a patient’s blood pressure is persistently above the speci ed target, it is worth strongly considering nicardipine in usion in pre erence to labetalol bolus dosing. Esmolol a very short-acting beta blocker, with an onset o action within 60 seconds and a duration o action o 10–20 minutes one o the pre erred agents in neurologic emergencies78 has a particular advantage in situations in which beta blockade is relatively contraindicated (asthma and copd exacerbations, or example), as its short duration o action allows it to be quickly stopped i complications arise may improve outcomes rom organ donation a er brain death when used to limit the autonomic storming that occurs79 animal data suggest that this is at least partially due to prevention o immediate negative myocardial changes that occur during brain death.80,81 t ese changes are not prevented by other antihypertensives. Enalaprilat an intravenous ace-inhibitor has a long duration o action and unpredictable e ect should be considered a second-line agent hydralazine a direct vasodilator has an unpredictable dose–response curve and up to a 12-hour duration in certain circumstances, may increase icp and reduce cpp82 should be considered second-line due to these concerns 346 ch apt er 21 nitroglycerine primarily lowers blood pressure by causing venodilation decreases cardiac output o limited utility in neurologic conditions nitroprusside quick-acting e ective at lowering blood pressure via arterial vasodilation 83 may cause increased icp and decreased cbf84 has the potential to result in cyanide toxicity may cause non-cyanide-mediated neuronal damage85 risks o administration in neurologic conditions usually outweigh the bene ts. Abnormalities—particularly o potassium, calcium, and magnesium—and these abnormalities should be sought and corrected concurrently with speci c treatments. All patients with new-onset arrhythmias should have an ekg per ormed, both to document the arrhythmia and to evaluate or ischemia as either a cause or consequence. What is atrial ibrillation, and how should it be managed?. Atrial brillation disorganized atrial activity and an irregular, o en case 21-1 (continued ) shortly a ter return rom angiography, the patient spontaneously develops a wide-complex tachycardia at a rate o 180 with a systolic blood pressure o 105. What medications and other interventions should be considered at this point?. Management o cardiac arrhythmias x in the nicu why is the management o cardiac arrhythmias relevant to an nicu population?. Cardiac arrhythmias are common in patients with acute neurologic injuries. T ey occur in 27% o stroke patients.86 up to 39% o icu stroke patients without preexisting cardiac disease develop arrhythmias.87 location a ects probability and type. Arrhythmias are more requent in right hemispheric in arcts.88 emporoparietal hemorrhages in particular are associated with ventricular tachycardia.89 patients with sah are at high risk o cardiac arrhythmias.88 management o the more common cardiac arrhythmias in neurologically injured patients will be discussed here. What are the basic principles o cardiac arrhythmia management?. When managing any arrhythmia it is important to note that it may be provoked or exacerbated by electrolyte rapid ventricular response common among stroke patients a well-described risk actor or ischemic stroke, so some o these patients may represent previously existing conditions that were only diagnosed as a result o having had a stroke. T e rst question that must be answered when managing a patient with newly diagnosed atrial brillation is whether he or she is stable or unstable. Patients with evidence o signi cant hypoper usion should undergo immediate electrical cardioversion even i the presence o an atrial clot cannot be excluded. O en icu patients may have multiple predisposing actors, such as hypovolemia or anemia, which must also be corrected or cardioversion to be success ul.
