  1. Emergencies in Hemodialysis Jeff Kaufhold, MD FACP Nephrology Associates 2007

  2. Seizures • Long term dialysis pt develops seizure near end of dialysis session. • No head injury or intracranial abnormality. After dialysis stopped, pt returns to baseline. • Calcium mag, K levels all normal. • Differential?

  3. Seizures • Hypotension, especially in a pt with hx of stroke. • Electrolyte abnormalities from dialysate (but these should persist after Tx) • Alkalosis with change in ionized Calcium • Reglan also associated. • Hypoxia, due to decreased resp drive.

  4. Hyperkalemia • Pt who normally watches diet and comes to her treatments has weakness and presents to ER. • K is 7.2. Gets tx at hospital and K normalizes. • She returns the next week with similar findings. • Why is her K suddenly a problem?

  5. Hyperkalemia • First thing to consider is her ACCESS. • If her AVF is developing a stenosis, she may not be receiving adequate clearance. • Any new meds? • Hungry bone syndrome, after parathyroidectomy is also a known cause.

  6. Malignant Hypertension • 37 y.o. male with severe htn and ESRD presents with mental status changes, dysarthria, and BP of 250/170 • Treated with Nipride to target BP of 200/100 • 2 days later, he develops agitation, tachycardia, hypotension. Anion Gap is increased.

  7. Malignant Hypertension • Cyanide Toxicity • Thiocyanate toxicity presents the same. • To avoid this you can: • Get them off Nipride ASAP, by immediately resuming outpt oral meds (I like q6h procardia XL) • Use another agent, such as Nitroglycerine, Labetolol drip. Expensive option is Corlepam.

  8. Shortness of Breath, CP • 56 y.o. male complains of SOB and SSCP minutes after starting treatment. • No hx of heart disease. • Tachy, hypotensive, Desats. • What to look for?

  9. SOB and CP • Infusions: IV iron, Antibiotics, IDPN • First Use phenomenon • Reaction to ETO sterilant (kidney was not rinsed sufficiently) • Bioincompatible kidney • PAN kidney in ACE treated pt. • Surreptitious hemorrhage • Pericardial effusion (may not have RV collapse if echo done off dialysis)

  10. Widespread Problems • Multiple patients begin complaining of abdominal pain, SOB, and hypo OR hypertension during treatment. • Patients labwork cannot be run due to interference from Hemolysis.

  11. Hemolysis • Consider chloramine release from water treatment system. • Consider tubing problem (narrow lumen can cause hemolysis). • Consider sterilant problem/ inadequate rinsing of reused kidneys.
