Neurolytic Intercostal Nerve Block

Thoracic paravertebral nerve at each level gives anterior and posterior branches. The anterior branch is the intercostal nerve which gives lateral and anterior cutaneous branches. They provide motor supply to abdominal wall muscles via T7-T11 and muscles of the forearm and hand via T1. They provide sensory innervation of the skin of the chest and abdomen anterolaterally. The intercostal nerves travel in the inferior part of the ribs posterior to the intercostal artery. Subcostal nerve comes...

Tricyclic Antidepressants

Tricyclic antidepressants are used for depression and neuropathic pain. They are inhibitors of reuptake of norepinephrine and serotonin in the descending projections from the brain to the dorsal horn of the spinal cord resulting in modulation of the incoming nociceptive signals. Norepinephrine seems to be more important for analgesia whereas serotonin is more important for antidepressant effects. The sedating effects may be helpful with sleep. Usually these agents are initiated as an evening...

Neurolytic Visceral Sympathetic Blocks

Neurolytic sympathetic blocks can be very helpful in controlling pain that is visceral in origin. Visceral pain can occur when visceral structures are involved with cancer due to pressure, invasion, or stretching. Visceral pain can be dull, squeezing, and poorly localized. Referred pain can occur due to visceral pain. For example, patient can experience pain in the shoulder when the diaphragm is involved in the tumor. Sympathetic block can help visceral pain only. This means that other forms of...

Which of the following is true about the use of antidepressants and their analgesic effects

Analgesic effects are only seen in patients who suffer from depression B. Depressed patients require higher doses for analgesic effect C. Antidepressants do not relieve pain if the patient suffers from depression D. Depressed patients respond faster to analgesic effects of antidepressants 4. Fluoxetine may be contraindicated if the patient is suffering from D. IBS (irritable bowel syndrome) 5. A 32-year-old man is in the emergency room with a fracture of his right forearm. He is in pain and...

Classification of Pain

Pain is a complicated physiological process that can be classified in terms of its duration, etiology, and physiology. Acute pain, which usually follows trauma to tissue, is limited in duration and is associated with temporal reductions in intensity. In contrast, chronic pain is of longer duration, often 3-6 months longer than expected. Chronic pain often has an unclear etiology and its prognosis is more unpredictable when compared to acute pain. Although acute pain and chronic pain have...

Anticonvulsant Drugs

Anticonvulsant drugs (ACDs) have efficacy in mitigating neuropathic pain, including trigeminal neuralgia and phantom limb pain (McQuay et al. 1995), as well as migraine (Pappagallo 2003, Snow et al. 2002). As with the antidepressants, analgesic differences exist among the ACDs with regard to utility across types of pain conditions. Carbamazepine is Food and Drug Administration (FDA)-approved for the treatment of trigeminal neuralgia gabapentin, for treatment of postherpetic neuralgia...

Peripheral Nerve Blocks of the Lower Extremity

Femoral nerve block provides anesthesia analgesia to the anterior thigh, including the flexor muscles of the hip and extensor muscles of the knee. Historically this block was also known as the 3-in-1 block, suggesting that the femoral, lateral femoral cutaneous, and obturator nerves could be blocked from a single injection at the femoral crease. However, it has been demonstrated that the femoral and lateral femoral cutaneous nerves can be reliably blocked by a single injection, but the...

Duration and Periodicity

To determine the duration and temporal characteristics regarding one's pain, the patient should be asked whether the pain is continuous, intermittent, pulsatile, or characterized by a wavelike rise and fall in intensity. Some physicians advocate the use of time-intensity curves to characterize how the pain starts, the rapidity with which it increases, the duration, and the manner by which the pain declines (Fig. 5.1). Additionally, the relationship of the pain CONTINUOUS PAIN, FLUCTUATING...

Traditional Principle of Acupuncture

Traditionally acupuncture is embedded in a complex theoretical framework that provides conceptual and therapeutic directions. Acupuncture relies on ordinary human sensory awareness, and its fundamental assertion is similar to the kindred philosophical systems of Confucianism and Taoism (Hahn 1982). The contemplation and reflection on sensory perceptions and ordinary appearances are sufficient to understand the human condition, including both health and illness. The foreign-sounding key words of...

Pharmacologic Treatment of Cancer Pain

Modified Who Analgesic Ladder

World Health Organization (WHO) developed guidelines for treatment of cancer pain (World Health Organization 1990, Zech 1995). It includes three-step analgesic ladder for pharmacologic management ofcancer pain. Application of the World Health Organization (WHO) analgesic ladder helps provide adequate analgesia in the majority of cases (Fig. 28.1) (Jacox et al. 1994, Miguel 2000, Patt 1993). The steps in the analgesic ladder are designed to treat mild, moderate and severe cancer pain Mild pain...

Headaches Due to Meningeal Irritation

These headaches are usually due to a meningeal infection or rupture of an aneurysm. Meningitis and subarachnoid hemorrhage are the most common causes. Diagnosis is based on the patient's symptoms and imaging such as a computed tomography (CT) or a magnetic resonance imaging (MRI). The patient may present with asudden onset of intense, deep pain, often worse in the neck, and evolving in minutes to hours. The pain can be generalized, bioc-cipital, or bifrontal. The patient may present with neck...

History of Acupuncture

Acupuncture is one of many therapeutic interventions utilized in traditional Chinese medicine (TCM). The seminal TCM textbook, Huang Di Nei Jing (Inner Canon of the Yellow Emperor or The Inner Canon of Huangdi), was compiled around 305-204 BCE (Fig. 16.1). This textbook covered the theoretical foundation of Chinese medicine (Unschuld 1985). It is composed of two volumes Shu Wen and Ling Shu. Each volume has 81 chapters and is written in a question and answer format between the mythical Huangdi...

Benzodiazepines

These agents may be useful to help with insomnia, making it easier to deal with pain or to treat anxiety which can play a role in pain states especially acute pain. However, it must always be remembered that these agents do not have any analgesic properties. Therefore they must be used with caution in acute pain, especially when high doses of opioids are required, as significant sedation and respiratory depression can occur in the benzodiazepine-na'ive patient. In an anxious patient with pain,...

Popliteal Nerve Block Distal Sciatic

This is a peripheral nerve block of the sciatic nerve performed more distal in the leg proximal to the popliteal crease. With the patient in the supine or prone position, the ultrasound probe is placed to scan in the transverse plane on the posterior surface of the popliteal fossa 5 cm or more proximal to the popliteal flexion crease of the knee (Fig. 21.11a). Subtle inclination of the ultrasound probe in the caudad or cephalad direction may be needed to produce ideal visualization of the...

Spine Injections

Side Effects Facet Injections

Back pain is one of the most common reasons for patients to seek medical attention. About two-thirds of adults will experience low back pain at least once in their lifetime (Rubin 2007). Its etiology is often unclear given that similar complaints and symptoms may result from various pathologic conditions and imaging studies do not always correlate. This makes accurate diagnosis and treatment difficult. Occupational injuries, compensation, and secondary gain issues confound the situation even...

Regional Anesthesia

Regional anesthesia, whether performed alone or most commonly in conjunction with general anesthesia, provides an excellent and safe source of intra-operative and postoperative analgesia for pediatric acute pain management as well as analgesia for pediatric chronic pain management. The popularity of regional anesthesia is underscored by its ability to decrease intra-operative and postoperative requirement for opioids, intra-operative titration of volatile anesthetics, and to minimize side...

Tunneled Epidural Catheter for Long Term use for Cancer Pain

As mentioned in earlier chapters, the epidural space continues from foramen magnum superiorly to the sacrococcygeal membrane inferiorly. Epidural space contains fat, blood vessels, and connective tissues (Stoelting and Miller 2000). Epidural catheter can be placed at any level in the lumbar, thoracic, or cervical level. Infusion can be delivered at either level to help pain in cancer patients. Tunneled catheter is more advantageous than non-tunneled catheter because if infection occurs at the...

Technique

Intranasal delivery of 4 lidocaine or 2 viscous lidocaine or 10 cocaine in the posterior pharynx superior to the middle turbinate is an effective and noninvasive approach. Cotton-tipped applicators soaked with local anesthetic left in the superior border of the middle turbinate for 20 min is a useful technique via the transnasal approach. This is achieved by the placement of a needle through the coronoid notch. Opening and closing the mouth helps in identifying the area anterior inferior to the...

Anxiolytics

Anxiety is a very common concomitant condition in patients with chronic pain, presenting as panic, PTSD, obsessive compulsive disorder (OCD), etc. Although anxiolytics do not possess intrinsic analgesic activity, anxiety is often accompanied by somatic complaints of chest pain, GI upset, or neurologic symptoms such as dysesthesias, headache, which may be relieved by anxiolysis. Benzodiazepines are also a mainstay in the treatment of restless legs syndrome (RLS). Although most RLS studies were...

Physical Management of Pain

Approaches for the physical management of pain include client education and training in methods to protect joints, prevention of pain and inflammation, work simplification, proper body mechanics, therapeutic exercise, work hardening programs, and physical agent modalities. The goal is to control pain and educate the client on strategies that can be used to more effectively manage the pain and allow engagement in enjoyable and meaningful occupations. Joint protection, work simplification, proper...

Hypogastric Plexus Block

Hypogastric Nerve Distribution

Hypogastric plexus block is located bilaterally in front of the anterolateral border of the lower 1 3 of L5 vertebral body. The ganglia are located in the retroperitoneum (Plancarte et al. 1997). Superior hypogastric plexus innervates the sympathetic structures of the lower abdominal and pelvic organs. Visceral pain is an important component in pelvic pain due to cancer. Pain relief from superior hypogastric plexus block is possible because afferent nerve fibers to the pelvic structures travel...

Headache of Temporal Arteritis

This headache is caused by inflammation of the cranial arteries and is usually seen in the elderly. It presents with increasingly intense throbbing or non-throbbing headaches. There is often a superimposed sharp, stabbing pain associated with thickened and tender arteries. The pain is usually unilateral, localized to the site of the affected arteries. However, it may also present as bilateral and explosive in nature in some patients. Pain may be present throughout the day and may be more severe...

Median Nerve Block

A brachial plexus block can be supplemented or rescued with a median nerve block for surgeries in the distribution of the median nerve or in the instance when a brachial plexus block may have spared the median nerve distribution. Fibers from C5-T1 spinal roots make up the median nerve. The nerve traverses the anterior-superior part of the axillary artery before exiting the axilla along with the brachial artery. The median nerve lies medial to the brachial artery at the level of the elbow and...

PCA Management

If the patient does not receive adequate pain relief with a given demand dose, increase the dose per activation using the parameters suggested in Table 18.6. Table 18.6 Usual patient-controlled analgesia demand dose changes for inadequate analgesia. Table 18.6 Usual patient-controlled analgesia demand dose changes for inadequate analgesia. A small subset of opioid-na'ive patients may prove that they need and can be safe with a continuous infusion. For example, if following several demand dose...

Celiac Plexus Block

Popliteal Nerve Block Sciatic Nerve Block in Popliteal Region

The sciatic nerve is a bundle consisting of the tibial and common peroneal nerves contained in an epineural sheath. A popliteal nerve block will block components of the sciatic nerve tibial and common peroneal at the level of the popliteal fossa where the two branches typically diverge. The common peroneal nerve gives sensory innervation to the inferior portion of the knee joint and lateral and posterior portion of the upper calf. The tibial nerve is a branch of the sciatic nerve and provides...

Neuromatrix Theory and the Biopsychosocial Model

Advances in the neuroscience of pain processing have provided support for the role of higher brain centers, i.e., those responsible for emotion and cognition, in influencing pain transmission from the periphery Melzack 1999 , lending support for the biopsychosocial approach. Abandoning the archaic Cartesian viewpoint of the brain as a passive recipient of pain information from the periphery, the neuromatrix model acknowledges that the brain is dynamically involved in the processing inhibition,...
