Director: Ann Malec, DNP, RN, NEA-BC
Medical Director: Alex Yevzlin, MD


I. PURPOSE

A. To describe preventative measures taken to prevent treatment related complications.
B. To provide guidance on quickly identifying hemodialysis treatment related complications
and provide direction for immediate corrective actions.
i. Common treatment related complications include: hypotension, cramping.
ii. Less common but serious complications include: Dialyzer Membrane Bio-
incompatibility Reaction, Pyrogenic Reaction, Hemolysis, Air emboli, Blood
Leak, Exsanguination, and Disequilibrium Syndrome.
C. For other complications, e.g., angina, chest pain or sudden change in patient condition,
summon the appropriate assistance 262-0000.
i. Blue Cart - unresponsive or life threatening emergencies
ii. Rapid Response - early recognition and intervention for deteriorating conditions.
iii. Acute Stroke Team – sudden onset of symptoms of a stroke.
For details refer to UWHC Administrative Policy 7.36 Emergency Response Team or
UW Health Clinical Policy 5.1.5 Acute Stroke Response for Adults.

II. GENERAL INFORMATION

A. Pyrogenic reaction – Temperature elevation within the first 45-78 minutes of dialysis.
1. Signs and symptoms include: chills, involuntary shaking, complaint of feeling
cold after initiation of dialysis, hypotension and/or hemodynamic instability,
myalgia (muscle pain) , headache, nausea and vomiting
2. Potential source of bacteria and/or endotoxins contamination includes dialysate,
product water, and/or the extracorporeal system.
B. Dialyzer Membrane Bio-incompatibility reactions have two forms
1. Type A: Occurs in the first 5-10 minutes of initiating dialysis, can progress to
anaphylaxis. Signs and symptoms include: nausea, flushed warm feeling and
uneasiness, agitation, chest tightness, back pain, acute bronchial restriction,
dyspnea, respiratory stridor, wheezing, itching and watery eyes.
2. Type B: Occurs 20-40 minutes after initiation of dialysis, signs and symptoms
are less sever and include: back pain, hypotension and chest pain.
Symptoms usually will resolve after the first hour.
C. Hemolysis – Destruction of red blood cells so that the hemoglobin and potassium are
released into the surrounding fluid.

Page 2 of 5
1. Signs and symptoms include: flushed warm feeling, chest and abdominal pain,
dyspnea, hypotension, dysrhythmias, burning pain in the access extremity and
clear translucent “cherry pop” colored blood in the venous blood line.
2. Hemolysis may result from mechanical, chemical or osmotic injury.
D. Air Emboli – Occurs when a large volume of air or foam (microbubbles) is introduced
into the heart or vascular system.
1. Signs and symptoms include: chest pain or tightness, shortness of breath,
coughing, tachycardia or other arrhythmias, loss of consciousness, or convulsions.
2. Potential source: Loose connections, separation of blood line, empty normal
saline bag and central venous catheter was not clamped and open to air.
E. Disequilibrium Syndrome– set of neurological symptoms that occur with the first few
dialysis sessions in patients with acute renal failure, pediatric patients or patients with
high blood urea nitrogen (BUN) levels.
1. Signs and symptoms include: Headache, nausea, vomiting, restlessness, twitching
to more sever tremors, disorientation, convulsions.
F. Exsanguination – Extreme blood loss
1. Signs and symptoms include: obvious blood on the floor or surroundings,
machine pressure change alarms, severe hypotension, shock, cardiac arrest.
2. Potential sources: Blood line separation, needle dislodging from access, rupture of
arteriovenous access, loose caps on central venous catheter.
G. Blood Leak – dialyzer membrane rupture that allows the passage of red blood cells into
the dialysate.
1. Signs and symptoms include: blood leak alarm, obvious frank blood in dialysate.

III. POLICIES

A. The following measures will be practiced in order to prevent treatment related
complications.
1. Water system monitoring – preformed at the beginning of every shift. If
treatments delivered in-center after hours the water system monitoring checks
need to be performed before the treatment begins. For details on water system
monitoring see HD Policy 2.0
2. Hemodialysis machine cleaning - Dialysis machines will be rinsed prior to first
use for the day and tested for residual disinfectant following routine cleaning
cycles where applicable. For details on cleaning and disinfection of hemodialysis
machines see HD Policy 2.6
3. Hemodialysis machine system alarm test - Alarm and pressure tests to insure
proper function of the dialysis machine will be conducted prior to each treatment.
4. Dialysate test - Dialysate pH and conductivity will be tested prior to each dialysis
treatment with an independent handheld meter and compared to machine readings
prior to each treatment.
5. Extracorporeal circuit & dialyzer – a visually inspection of the extracorporeal
circuit is conducted prior to or with initiation of each treatment and includes:
 Checking expiration dates and blood lines for defect,
 Blood line connections are secure,
 Caps and clamps on the blood lines and patient access are working properly,
 Venous line tubing is properly placed in line clamp,

Page 3 of 5
 Hemodialysis needles are secured with tape and the blood lines are secured to
reduce pulling during treatment,
 Dialysis should be initiated within 4 hours of being primed.
6. Systems checks during dialysis - special attention should be paid to the
extracorporeal circuit during initiation and discontinuation of dialysis for the
presence of air. Unless ordered to the contrary connect both arterial and venous
blood lines are connected to the patient’s access at initiation of hemodialysis.
Arterial and venous pressure readings are assessed and monitored during
treatment, the extracorporeal circuit is flushed to assess for clotting and the
normal saline administration line is to be double clamped during treatment.

B. Dialyzer Membrane Bio-incompatibility reaction
1. Dialyzers will be primed according to manufactures recommendations.

of hypotension.
2. Place patient in Trendelenburg as tolerated.
3. Pause ultrafiltration if no relief from symptoms with repeated normal saline boluses.
4. Consider use of ultrafiltration and/or sodium/conductivity profiles to adjust
ultrafiltration rate based on the patient’s symptoms.
5. Notify provider of assessment findings and patient’s response to interventions and
