How are hemorrhagic shock and hypovolemic shock different?

How are hemorrhagic shock and hypovolemic shock  different?

See below : Basically hypo-volumic shock is caused by loss of electrolytes and water from the body. Hemmorhagic shock on the other hand suggests massive loss of blood. ...Read more

How are hemorrhagic shock and hypovolemic shock different?

How are hemorrhagic shock and hypovolemic shock different?

Shock: Hemorrhagic shock occurs with a loss of blood and hypovolemic shock can occur with fluid losses, from diarrhea for example, without the loss of blood. Both have low BP and are caused by a volume deficit in the vascular system. Hypovolemic shock can be treated with IV fluids to increase the bp, while hemorrhagic shock needs to have blood transfused as well to increase the BP of the patient. ...Read more

Is ruptured brain abscess considered brain injury or traumatic brain injury?

Is  ruptured brain abscess considered brain injury or traumatic brain injury?

No: A brain abscess is a medical emergency and is due to a localized brain infection. If it ruptures, meningitis could occur and cause death. Unless there has been an open head injury, trauma does not directly cause infection. Physical injury such as falling and striking the head results maybe in "traumatic brain injury". ...Read more

Is there some differences between shock cardiogenic, shock hipovolemic, and shock septic?

Is there some differences between shock cardiogenic, shock hipovolemic, and shock septic?

Yes: Shock essentialy is very low BP and no urine output.And usually unconciousness this could be due to weakness of heart muscle (cardiogenic), severe dehydration and low intravascular volume (hypovolemic) or severe infection (septic). ...Read more

Difference between "brain hemorrhage" and "brain attack/stroke" ?

Difference between "brain hemorrhage" and "brain attack/stroke" ?

A few: A brain attack or stroke maybe from lack of blood flow(ischemic) or a bleed(either clot/embolism or aneurysm) in the brain(intraparenchemal). Both results in death of brain tissue. Other sources of hemorrhage can be in the surrounding tissues such as subdural(around the brain) or subarachnoid(around brain or spinal cord). ...Read more

Does multiple head traumas cause brain ischemia?

Post-traumatic: Repetitive head trauma results in tissue changes quite similar to alzheimers but the lesions are closer to the brain surface. This was first noted in "punch drunk syndrome" in boxing. There is likely some affect on blood flow (ischemia), as one could conceive of a local type of bruising, but this not fully clarified. Regardless the nfl and nhl are both paying a lot of attention these days. ...Read more

Does hyperbaric oxygen help brain injury or stroke?

Does hyperbaric oxygen help brain injury or stroke?

Yes: We have used hbot for brain injuries of all types for over 10 years and have gotten excellent results. If i ever have a condition of this kind, an hbot chamber is one of the first places i want to be. Jain's textbook of hyperbaric medicine is a good starting place for info about the effects of hbot. ...Read more

Traumatic brain injury always permanent?

Traumatic brain injury always permanent?

Depends on a lot: This is often the debate which engages forensic neuropsychologists (see http://forensicneuropsychology.Com) and forensic neurologists. Results can vary greatly even with similar ct or MRI findings. Generally severity, presence of intracranial bleeding, elevated icp, early or especially post-traumatic seizures, locaiton of injury, shearing, and pre-injury factors ie. Age, prior injury, health etc. ...Read more

Difference between "brain hemorrhage" and "brain attack" ?

Difference between "brain hemorrhage" and "brain attack" ?

Bleeding vs ischemia: Hemorrhage refers to bleeding which can happen due to trauma, hypertension, aneurysm, tumor or stroke. Brain attack refers to a transient ischemic attack in which blood flow decreases to the brain without causing a stroke. ...Read more

Could drinking kill brain cells and cause brain damage?

Could drinking kill brain cells and cause brain damage?

Afffect nerve fibers: Most prominent changes associated with alcohol consumption involve myelinated massive bundles of nerve fibers that interconnect neurons in different regions of the brain. Loss of memory, slowed thinking, impaired problem solving and decision making are especially vulnerable to damage caused by alcohol consumption, because it disrupts white matter connections to the cerebral cortex and deep brain. ...Read more

Can Ct Scan damage brain , effect activity of brain?

Can Ct Scan damage brain , effect activity of brain?

No: The x ray radiation in a CT has no measurable or known effect on neural tissues. 1) dose is way too low and 2) nerves are relatively radioresistant since the cells don't reproduce very fast, if at all. There is a theoretical risk of cataracts and cancer years later, but this is incredibly small esp. for a single scan and controversial anyway. ...Read more
