Neuropathic Pain Nociceptive PainChronic pain (months/years) Acute pain (hours or days)

Caused by injury or disease to nerves

Caused by injury or inflammation that affects both the muscles and

joints

Mild to excruciating pain that can last indefinitely

Moderate to severe pain that disappears when the injury heals

Causes extreme sensitivity to touch –simply wearing light

clothing is painful

Causes sore, achy muscles

Sufferers can become depressed or socially withdrawn because they see no relief in sight and

may experience sleep problems

Sufferers can become anxious and distressed but optimistic

about relief from pain

sehingga timbul nyeri

Neuropathic PainNeuropathic Pain

• Pain disebabkan oleh kerusakan pada SSP atau SST

• Keluhan Pain biasanya : rasa geli, rasa rasa tertusuk, rasa tersengat listrik, rasa terbakar dan disertai dengan rasa kesemutan atau rasa baal.

• Pain timbul sepanjang teritori yang persarafi oleh nervus ybs (nervus, plexus, radix, spinal cord, brain)

• Biasanya kronik (e.g. postherpetic neuralgia, poststroke pain)

• Bila di terapi dengan NSAID hasilnya kurang memuaskan

What is Neuropathic Pain ? What is Neuropathic Pain ?

• Jutaan nervus saling

berhubungan di dalam tubuh :

– Nerves menghubungkan otak

dan tubuh utk berkomunikasi

– If you accidentally grab a hot

iron, nerves in your hand send

a message to the brain that

you are touching something

hot. As a result, your hand

feels a burning pain

Price SA. Pathophysiology: Clinical Concepts of Disease Processes. 5th ed; 1997

How Neuropathic Pain Occurs How Neuropathic Pain Occurs

• Jika nerves rusak atau terluka maka

fungsinya terganggu :

– Dapat mengirimkan sinyal yang salah ke

otak

– Nervus yang rusak dapat memberitahu otak

bahwa ada rasa terbakar pada telapak kaki

walaupun tidak menapak pada suatu yang

panas.

Price SA. Pathophysiology: Clinical Concepts of Disease Processes. 5th ed; 1997

How Neuropathic Pain Happens How Neuropathic Pain Happens

Polyneuropathy is caused by the degeneration of axon terminals and results in symmetric distal sensory loss with shading to normal sensation. A compression neuropathy often results in demyelination with the axon left relatively intact. Sensory loss follows a radicular pattern. When the neuronal cell body dies the condition is called "neuronopathy." If the cell body is in the sensory ganglion the condition is often referred to as "ganglionopathy." The pattern is usually random

Axonal polyneuropathyDemyelinating NeuropathyNeuronopathy (Ganglionopathy)

• Up to 7.7 % of people in Europe have neuropathic

pain

– 3 million people, or 7.5% in the United Kingdom

– 2.5 million people, or 6.4% in France

– 3.5 million people, or 6.0% in Germany

– 2.1 million people, or 7.7% in Spain

• It often is under-diagnosed and under-

treated

People with neuropathic pain report:• Difficulty sleeping• A lack of energy• Drowsiness • Difficulty concentrating• Strained relationships with family and friends• An inability to work, walk, or even wear clothes as

the contact with their skin can cause an unbearable burning pain

Progression of herpes zoster. A cluster of small bumps (1) turns into blisters (2). The blisters fill with lymph, break open (3), crust over (4), and finally disappear. Postherpetic neuralgia can sometimes occur due to nerve damage (5),

Treatment for Post Herpetic Treatment for Post Herpetic Neuralgia Neuralgia 1. For acute Herpes Zoster :

- Acyclovir 5 x 800 mg / day 7 days

2. For acute and cronic Post Herpetic Neuralgia :Pain killer : - Gabapentin 3 x 300 mg/day – 3 x 1200 mg/day 2 – 6 months- NSAID 1 – 2 weeks

Trigeminal Neuralgia Trigeminal Neuralgia Ada sekitar 15,000 kasus baru yang didiagnosa dlm setahun dan 90% kasus timbul pada usia di atas 40 th. Prevalensi sekitar 12 juta pasien dengan ratio ♀ : ♂ 1.5:1. Keluhan : nyeri mendadak, Stabbing (rasa tertusuk), shooting (rasa perih,panas), electric shock-like pain (rasa tersengat listrik) di sepanjang area maxillary and mandibular, sesisi. Rasa nyeri timbul spontan atau terstimuli dgn sentuhan, air dingin, mengunyah, berbicara, gerakan wajah, menyikat gigi atau stress emosional, dan berulang.

Trigeminal neuralgia juga menyebabkan chepalgia yang berat dan intermittent (hilang timbul).Trigger zones biasanya di daerah pusat wajah dan sekitar hidung dan bibir dan ukurannya kecil (1-2 mm). Penyebab Trigeminal Neuralgia karena demyelinisasi dan irritasi pada nervus trigeminal.

Anatomi Nervus V Anatomi Nervus V

- Trigeminal neuralgia (TN) = tic douloureux adalah suatu kondisi yang

mengenai nervus trigeminal (N.V).

- Nervus ini adalah salah satu nervus terbesar di kepala dan berfungsi

untuk menyalurkan impuls rabaan, tekanan, suhu, dari area wajah,

rahang, gusi, dahi, sekitar mata.

Cause of trigeminal neuralgia

- The exact cause of trigeminal neuralgia is controversial, but it is

suggested that an area of vascular compression where the

trigeminal nerve enters the brain may be the culprit.

- This compression may cause damage to the myelin sheath (the

insulating cover of a nerve fiber) that surrounds the trigeminal

nerve. Other precipitating factors include multiple sclerosis and

hypertension.

Etiologi Trigeminal Neuralgia Etiologi Trigeminal Neuralgia

- Pemeriksaan Neurologis biasanya normal.

- Yang harus dipikirkan adalah ‘sesuatu yang lebih dari sekedar’

trigeminal Neuralgia misal : multiple sclerosis atau tumor.

- MRI dgn atau tanpa kontras tetap normal jika tidak ada lesi.

- Biasanya diagnosa Trigeminal Neuralgia ditegakkan berdasarkan

anamnesa dan therapeutic trial.

- Sering terjadi pasien tidak diterapi dengan benar karena diagnosanya

sulit ditegakkan.

- Penyakit lain yang menyerupai Trigeminal Neuralgia : dental

disorders, sinus infections, temporal arteritis, migraine headaches, and

psychological disorders.

- Jika salah diagnosa maka bisa menyebabkan : ekstraksi gigi yang

tidak perlu, terapi root canals, operasi sinus, biopsi dan terapi

antibiotik.

- Mekanisme kerja dari obat obat tsb adl menghambat impuls nyeri
