7. Depending upon the level of contamination and the specific contaminant, patients may have acute onset of symptoms at the time of exposure or develop symptoms over time, reflecting chronic exposure Handbook of dialysis, Daugirdas, 5th edition, 2015

9. 2013 Jul-Aug; 26(4): 427–438 383,900 individuals in the U.S. undergo maintenance hemodialysis

19. Early symptoms include: headache, nausea, disorientation, restlessness, blurred vision, asterixis. However, may progress to confusion, seizures, coma, and even death. 2008 Sep-Oct;21(5):493-8

20. 2016 Jan-Dec; 5: 2048004016677687 There is no diagnostic test for DDS, and the diagnosis is one of exclusion CNS imaging Electrolytes and Glucose assessment

21. • Symptomatic R + Dialysis should be stopped if the patient develops seizures, coma, and/or obtundation • Patency of the airway should also be ensured • Hypertonic solution !! 2017 Feb 7;12(2):357-369

22. For high risk: Slow urea removal • Therapy can be initiated with two ho of dialysis • Low blood flow ra 150 to 250 mL/min • URR: 40% • (0.9 to 1.2 m2) • Hypertonic solution !! 2017 Feb 7;12(2):357-369

26. pp 151-158

27. pp 151-158 • Nasal oxygen • If the anginal episode is associated with hypotension: elevating the feet and cautiously administering saline • Sublingual nitroglycerin can be given if the blood pressure has increased to a clinically acceptable value • Blood flow rate should be reduced and UF should be stopped until the anginal episode subsides • ECG

35. 2017 Feb 7;12(2):357-369 Venous air embolism may arise from 4 possible areas of air entry into the dialysis circuit

37. • Treatment of suspected air embolism includes clamping the venous line and stopping the blood pump. • The patient should be positioned on the left side, in a supine position, with the chest and head tilted downward. • Cardiorespiratory support. • Administration of 100 percent oxygen by either mask or endotracheal tube. • Attempted percutaneous aspiration of air from the ventricle may be required.

50. The treatment of arrhythmias that occur in dialysis patients, either during or between dialysis sessions, is similar to their treatment in the nondialysis patient However, appropriate dosing of medications based upon the absence of renal function is always required
