Nevada Injury Lawyer - Personal Injury Lawyer - Las Vegas Injury Lawyer - Injury Claims Spinal laminectomy (also known as spinal decompression) involves the removal of the lamina (usually both sides) to increase the size of the spinal canal and relieve pressure on the spinal cord and nerve roots. Shock is characterized by cold and sweaty skin, weak and rapid pulse, irregular breathing, dry mouth, dilated pupils, and reduced flow of urine. Shock can be caused by internal or external bleeding (hypovolemic shock), dehydration, burns, or severe vomiting and/or diarrhea--all of which involve the loss of large amounts of bodily fluids. accidentclaims.org /injury.html   (6248 words)

London ambulance service Unofficial. Shock In hypovolemic shock, preload is decreased, afterload is increased, and the myocardial contractility remains normal. In early septic shock, the preload and afterload are decreased, and the myocardial contractility is increased. In late septic shock, the preload and afterload are increased and the myocardial contractility is decreased. home.freeuk.net /lond.ambulance/shock2.html   (1049 words)

Spinal shock - Wikipedia, the free encyclopedia Spinal shock is an initial period of “hypotonia” that can result from damage to the motor cortex or other brain regions concerned with the activation of motor neurons. Since many of the descending motor nerves cross the midline, spinal shock originating from damage on one side of the brain (such as damage due to a stroke) can often be detected as reduced muscle activity on the contralateral side of the body. Some control of trunk muscles is often preserved because of remaining brainstem pathways and spinal circuits that control midline musculature. en.wikipedia.org /wiki/Spinal_shock   (160 words)

Shock   (Site not responding. Last check: ) Septic shock is associated with sepsis which is the presence of pathogenic organisms in the blood or tissues. In distributive shock, as in early septic shock, the preload and afterload are decreased while the myocardial contractility is increased. The third cause of shock in neonates is obstructive left heart syndromes, such as critical aortic stenosis, critical coarctation of the aorta, hypoplasic left heart, and interrupted aortic arch. home.coqui.net /myrna/shock.htm   (2490 words)

eMedicine - Spinal Cord Injury: Definition, Epidemiology, Pathophysiology : Article Excerpt by: Segun T Dawodu, MD, ... Spinal cord injury (SCI) is an insult to the spinal cord resulting in a change, either temporary or permanent, in its normal motor, sensory, or autonomic function. Spinal shock is a state of transient physiological (rather than anatomical) reflex depression of cord function below the level of injury with associated loss of all sensorimotor functions. Neurogenic shock is manifested by the triad of hypotension, bradycardia, and hypothermia. www.emedicine.com /pmr/byname/spinal-cord-injury--definition-epidemiology-pathophysiology.htm   (591 words)

HerbChina2000.com - Herbal Remedies - Spinal cord trauma Spinal cord trauma, also call Spinal cord compression or injury, is damage to the spinal cord that results from direct injury to the cord itself, or from indirect injury from damage to the bones, soft tissues, and blood vessels surrounding the spinal cord. Spinal shock - a state of transient physiological reflex depression of cord function below the level of injury with associated loss of all sensorimotor functions. Neurogenic shock - manifested by the triad of hypotension, bradycardia, and hypothermia. www.herbchina2000.com /therapies/NSC.shtml   (851 words)

Quiz of the Week: June 7, 2000 Spinal shock is characterized by flaccid paralysis (loss of bladder tone) below the level of the injury, and loss of spinal cord reflexes including bladder and bowel sphincter control. Spinal shock often coincides with neurogenic shock, which is evidenced by loss of autonomic control (bradycardia, vasodilation, hypotension). Spinal shock can persist for several weeks, and is associated with an inability to retain urine or bowel contents. www.lhsc.on.ca /critcare/icu/eduquiz/jul7a00.html   (410 words)

Spinal Injury Spinal injuries are often a consequence of trauma and the patient may well have multiple other injuries. Deliberate damage to the spinal cord, using sharpened bicycle spokes is not an uncommon cause of paraplegia in South Africa. The spinal canal is narrower in the thoracic segment relative to the width of the cord, so that when vertebral displacement occurs it is more likely to damage the cord. www.usyd.edu.au /anaes/lectures/spinal_inj_pjc95.html   (4204 words)

Neurological Exam: Spinal Cord: Lesions: Vascular Diseases - Anterior Spinal Artery Syndrome   (Site not responding. Last check: ) Damage from such lesions reflects the pattern of the blood supply where a) posterior spinal arteries supply the dorsal part of the cord, 2) anterior spinal arteries supply the anterior 2/3rds of cord, and 3) the arterial vasocorona in the pial plexus supplies the periphery of the anterolateral cord. Spinal shock - An infarction of the anterior spinal artery usually involves the gray and white matter (less frequently only the gray) of the anterolateral cord. The suddenness of the lesion leads to "spinal shock" and hence the voluntary and involuntary paralyses and areflexia. isc.temple.edu /neuroanatomy/lab/lesions/5.htm   (303 words)

Chapter 16 - Initiation and Control of Movement Spinal shock is understandable in terms of the excitability of central neurons, among them the alpha-motoneurons, which is determined by the sum total of the excitatory and inhibitory synaptic inputs to them (see Chapter 13). An indicator of the onset of the period of recovery from spinal shock is the appearance of flexion reflexes, which are mediated by polysynaptic pathways. During spinal shock, the bladder wall is atonic, with increased sphincter tone, resulting in extensive dilatation of the bladder. www.unmc.edu /Physiology/Mann/mann16.html   (14692 words)

Acute Management of a Spinal Cord Injury - Disaboom Spinal shock is a condition that involves the lack of tone or contraction of the muscles below the level of injury, loss of tendon reflexes, and possibly neurogenic shock. A commonly described cause after spinal cord injury is the interference with the normal processes of the sympathetic nervous system as it relates to the blood vessels. Patients with spinal cord injury at C3 and C4 usually require ventilator support initially, but studies (Wicks and Menter) reported that 51% of C3 and 78% of C4 patients were able to be weaned off of the ventilator. www.disaboom.com /Health/Spinal-Cord-Injury/Core-Knowledge/Spinal-Cord-Injury-The-First-Few-Weeks.aspx   (4178 words)

Anatomy and Pathophysiology The spinal (or vertebral) column is composed of 33 bony rings or vertebrae, named for the region of the spine in which they are located and numbered cephalad to caudal: 7 cervical vertebrae (C1-7), 12 thoracic vertebrae (T1-12), 5 lumbar vertebrae (L1-5), 5 vertebrae fused as the sacrum (S1-5), and 4 coccygeal vertebrae. The spinal cord extends from the base of the brain through the spinal canal to the second lumbar vertebra (L2), with nerves exiting the cord between each pair of vertebrae and continuing through the spinal canal as the cauda equina. Spinal shock recovery can, therefore, be accompanied by complications such as autonomic hyperreflexia, and sexual, bladder, and autonomic dysfunctions. calder.med.miami.edu /providers/NURSING/anat.html   (691 words)

Spinal Cord Shock When a spinal cord injury is caused due to trauma, the body goes into a state known as spinal shock. While spinal shock begins within a few minutes of the injury, it make take several hours before the full effects occur. During spinal shock the nervous system is unable to transmit signals, some of which may return once spinal shock has subsided, the time spinal shock lasts for is approximately 4-6 weeks following the injury. www.spinal-injury.net /spinal-cord-shock.htm   (382 words)

spinal cord shock When the spinal cord is severely injured or partially severed, there is paralysis and loss of sensation of the parts of the body below the level of the injury. In spinal SHOCK there is also temporary loss of the spinal reflex functions. In spinal shock, there is usually no loss of consciousness unless the blood pressure drops very low from the blood vessel dilation. www.medhelp.org /forums/neuro/archive/707.html   (476 words)

Spinal Cord Injuries - New Treatments, May 2, 2006 Acute traumatic spinal cord injury predominantly is a disease affecting young males. Spinal shock, which usually occurs in conjunction with a severe spinal cord injury, is a concussive injury to the spinal cord producing total neurologic dysfunction distal to the site of the injury. Spinal shock also can result in autonomic dysfunction because of interruption of sympathetic innervation and can lead to hypotension, relative bradycardia from unopposed vagal stimulation, and warm peripheral extremities. www.ccspublishing.com /journals2a/spinal_injuries.htm   (973 words)

Medical Online In cervical and thoracic spinal cord injuries, Neurogenic shock with bradycardia and hypotension are common. Spinal cord ischaemia may be due to hypotension (either from spinal shock or hypovolaemia) and can cause increased cord damage and extend the neurological deficit. Spinal boards should be used for the shortest, practicable periods of time, and the slats of the Jordan Frame removed between uses to prevent pressure areas. www.medicalonline.com.au /medical/services/spinal/acute.html   (3375 words)

Shock at The Medical Dictionary The single most common cause of shock is blood volume loss, resulting from a serious wound or a severe burn leading to hypovolemic shock. The rarest cause of shock is acute spinal cord injury leading to neurogenic shock. Shock is associated with impairment of microvascular flow. the-medical-dictionary.com /shock.htm   (683 words)

SPINAL INJURIES   (Site not responding. Last check: ) It is the spinal cord, through its attached nerve roots, which provides the means by which we breathe, move and sense. Any injury to the spinal cord has serious ramifications for our ability to function normally, and a separation, or ‘lesion’, of the cord may cause quadriplegia, paraplegia, or chronic painful conditions, dependent on the location of the injury. Spinal shock is an injury where the spinal column is subject to a forceful blow, but no lesion occurs. www.parasolemt.com.au /Manual/spinalinjuries.asp   (574 words)

Untitled Document During the initial phase of spinal cord injury, the patient is experiencing "spinal shock." Basically, spinal shock is the result of swelling of the spinal cord. Bladder management for a patient in spinal shock is frequently urinary catheterization. Spinal shock, or depression of the reflexes, generally lasts from 1 to 2 months, when the spinal reflexes return. www.rnceus.com /uro/man.htm   (517 words)

The Autonomic Nervous System A lesion of the spinal cord itself, in which voluntary control of the bowel and bladder is affected, but which does not affect the parasympathetic outflow leads to an automatic bladder once spinal shock has worn off. Initially during spinal shock, the skin below the level of the lesion is dry, pale and cool but at a later stage profuse sweating in the affected area is common and can be provoked by stimulus of the such as stroking. Signs of shock are not identical with those of sympathetic nervous arousal but are more complex since they include signs associated with the impact of the stressor upon the body. www.jdaross.cwc.net /Autonomic/ANS6.htm   (1011 words)

Orlando Florida Spinal Injury Attorneys Lake County Accident Lawyers A: Spinal cord injury (SCI) is damage to the spinal cord resulting in a loss of function, such as mobility or physical sensation. The spinal cord is often injured if the vertebrae, normally held in place by strong ligaments and muscles, are pushed or pulled out of proper alignment. Spinal cord injury (SCI) is a term used to describe any injury to the spinal cord that results in a loss of sensation or function in the body. www.flspinalinjury.com   (818 words)

Broward County Spinal Cord Injury Lawyer :: Spinal Cord Injuries :: Hollywood, Florida Back Accident Attorney Spinal cord injury (SCI) when cells within the spinal cord are damaged or when the nerve tracts that relay signals up and down the spinal cord are severed.

eLetters — The Royal College of Surgeons of England   (Site not responding. Last check: ) While there is no doubt that Admiral Nelson had spinal shock, which is the complete lack of function of the spinal cord demonstrated by a lack of reflexes and limb flaccidity following a cord injury (in this instance the passage of the musket round), this did not cause his hypotension. The cause of this was neurogenic shock, which is a cardiovascular phenomenon consisting of a loss of vasomotor tone and the loss of sympathetic innervation to the heart following a disruption of the sympathetic pathways in the spinal cord. The recovery from spinal shock, as demonstrated by the return of spinal reflexes such as the bulbocavernosus reflex, indicate that the degree of cord damage can be quantified from assessing what remains of cord function. www.rcseng.ac.uk /publications/eletters/?article_id=49   (916 words)

Spinal Cord - Spasticity after spinal cord injury Similarly, of those individuals reporting spasticity in the Stockholm Spinal Cord Injury Study, 40% reported their spasticity to be problematic, in that ADL were restricted and/or the spasticity caused pain. The lower motor neurons are of two types, both of which originate in the ventral horn of the spinal cord: (1) alpha motor neurons project to extrafusal skeletal fibers and (2) gamma motor neurons project to intrafusal muscle fibers within the muscle spindle. Epidural spinal cord stimulation for the control of spasticity in spinal cord injury patients lacks long-term efficacy and is not cost-effective. www.nature.com /sc/journal/v43/n10/full/3101757a.html   (5728 words)

Spasticity | Paralysis Resource Center Spasticity is usually caused by damage to the portion of the brain or spinal cord that controls voluntary movement. When individuals are first injured, their muscles are weak and flexible because of what’s called spinal shock: the body’s reflexes are absent below the level of injury; this usually lasts for a few weeks or several months. Because the spinal cord is not as efficient as the brain, the signals that are sent back to the site of the sensation are often over exaggerated. www.paralysis.org /site/c.erJMJUOxFmH/b.1314471/k.360A/Spasticity.htm   (771 words)

Female patients are affected mainly in the first 4 decades of life, whereas the incidence among male patients is distributed more evenly, with a peak in the third decade of life (see Media file 1). www.emedicine.com /emerg/byname/spinal-cord-infections.htm   (740 words)

Shock, circulatory   (Site not responding. Last check: ) Hypovolemic shock - cardiac output is severely reduced due to loss of intravascular volume which results in reduced return of venous blood to the heart. Obstructive shock - cardiac output is severely reduced by vascular obstruction of venous return to the heart (vena cava syndrome), compression of the heart, (pericardial tamponade, tension pneumothorax) or outflow from the heart (aortic dissection, pulmonary embolism) High output or vasodilating shock (most often due to sepsis or septic like states such as toxic shock) is unique in that cardiac output is normal or elevated, but not distributed appropriately, resulting in over perfusion of some tissues and underperfusion (to the point of critical ischemia) of other tissues. www.5mcc.com /Assets/SUMMARY/TP0844.html   (337 words)

Clinical Simulations: Shock Management   (Site not responding. Last check: ) Focusses on the care of an elderly male patient who sustains a spinal cord injury in a car accident and subsequently develops spinal shock. Reviews the nursing assessment and management of cardiogenic shock, the care of a patient with a pulmonary artery catheter, and the nursing management of the patient on an intra-aortic balloon pump. Calls on the learner's understanding of the pathophysiology of hypovolaemic shock, conscious sedation, internal bleeding, and complications resulting from a blood transfusion. www.osl.u-net.com /m324.htm   (267 words)

Autonomic Dysreflexia In spinal cord injury, bladder sphincter relaxation is absent, leading to urinary retention. As soon as hourly urine output is no longer necessary, the indwelling bladder catheter should be removed to reduce the risk of urinary tract infections (a life-threatening complication of acute spinal cord injury). Spinal shock can persist for several weeks, and is associated with an inability to www.lhsc.on.ca /critcare/icu/edubriefs/bladder.html   (339 words)
