Biggest Issue …
Respiratory Failure from intercostal and
diapragmatic muscle paralysis
RAPID progression: 25% will need ventilator within 18
days!

Guillain-Barre’ Syndrome
 Autoimmune Disorder
 Inflammatory Version also
 Guillain-Barre syndrome is a rare disorder
 Not hereditary
 Cause unknown
4
Guillain-Barre’ Syndrome
 Immune system attacks peripheral nerve cell
myelin proteins (Rarely involves the brain)
 Causes varying degrees of muscle weakness and paralysis
 Spares the Schwann cells which produce myelin --
- remyelinazation and recovery
5
Motor & Sensory Neurons

Triggers?
Recent History of:
•
•
•
•
Viral illness
Vaccination
Surgery
Acute Illness
7
S & S’s
 SEVERE weakness and numbness in legs and arms
 PAIN d/t demyelinization
 Ascending weakness with dyskinesia (inability to move
voluntarily)
 Loss of feeling + movement (paralysis)
 Severe Bradycardia (pacemaker sometimes)
8
DIAGNOSTICS
Lumbar Puncture (LP) - cerebrospinal fluid with
elevated protein level
Electromyogram (EMG) records muscle
activity
which can show loss of reflexes d/t the
disease's
characteristic slowing of nerve
responses
Nerve Conduction Velocity (NCV) Performed
with EMG, and together, they are often referred
to as EMG/NCV studies. NCV records the speed at
which signals travel along the nerves
9
Severe GBS
Medical Emergency
 Total paralysis
 Potentially dangerous fluctuations in Pulse and BP
 25% unable to breathe without respiratory assistance
 Muscles for eye movement, speaking, chewing and swallowing also
become weak or paralyzed
may
 Often need long-term rehabilitation to regain normal independence
 As many as 15% experience lasting physical impairment
 In 3% – 8% can be fatal d/t complications
10
Treatment
 Plasmapheresis to decrease circulating antibodies
 EKG monitoring for Autonomic Dysfunction
 Immunoglobulin therapy
 Hormonal therapy
 Physical therapy (to increase muscle flexibility and strength)
11
Nursing Care
 Maintain Patent Airway
 HOB elevated
 C&DB Q2H / spirometry / chest physiotherapy
 Monitor Vitals vigilently
 Pain management
12
Collaborative Goals
 Reducing and/or managing symptoms
 Preventing complications
 Provide adaptive devices to increase
mobility and self-care
13
Prognosis
 Most people (85%) recover from even the most severe cases of
GBS with minimal residual symptoms
 Quick diagnosis & treatment may lessen the severity of GBS
and reduce recovery time
 The signs and symptoms of GBS may last days, weeks or
months before muscle sensation begins to return. Regaining
pre-illness strength and functioning is slow, sometimes
requiring months or years. However, most people with GBS
return to normal within months
