What are the signs and symptoms of spinal and neurogenic shock?

The classic presentation of neurogenic shock is hypotension caused by profound vasodilation from loss of sympathetic tone and bradycardia. The bradaycardia is typical of spinal transection above T-4. As T-4 is responsible for cardiac innervation.
Spinal shock is broken down into 4 phases
Phase one - complete loss of reflex response, sensitivity, and flaccid paralysis at and below the level of the spinal trauma.
Phase two - (day 1-3) slight return of some reflexes (i.e. stretch reflex) below site of injury
Phase three - (1 - 3weeks) Hyperreflexia occurs. this is a result of increasing numbers of post-synapitic cholinergic receptors (up regulations) and lack of feedback from the CNS below the level of the injury. (do not give depolarizing paralytics to these patients ... anesthesia/nursing pearl)
phase four -1m to 12months - continued increasing hyperreflexia w/ spacticity. nearing one year patients with spinal injuries are also at risk for autonomic hyperreflexia with spinal injuries that occur from T-6 to T-10.

What are the Late signs or symptoms for shock?
Depending on the primary etiology for shock, signs/symptoms will vary. Usually, evidence of profound or severe shock, without medical interventions, consist of severe neurological deficits (obtunded, coma), however, this is more likely secondary to the effects of shock (uremia, acidosis, hypoxia). Purely speaking, the late sign/symptom of shock is death. Shock in of itself is already a late sign/symptom (progression) of a primary insult to the body (cardiogenic: myocardial infarction or heart attack, heart failure; distributive: Infection, anaphylaxis, neurogenic; Hypovolemic: hemorrhage). So, the answer is death.
Vital signs for a spinal cord injury?
Neurogenic shock is characterized by severe autonomic dysfunction, resulting in hypotension, relative bradycardia, peripheral vasodilation, and hypothermia. It does not usually occur with spinal cord injury below the level of T6. Shock associated with a spinal cord injury involving the lower thoracic cord must be considered hemorrhagic until proven otherwise. Spinal shock is defined as the complete loss of all neurologic function, including reflexes and rectal tone, below a specific level that is associated with autonomic dysfunction. Neurogenic shock refers to the hemodynamic triad of hypotension, bradycardia, and peripheral vasodilation resulting from autonomic dysfunction and the interruption of sympathetic nervous system control in acute spinal cord injury.

What are the signs and symptoms of neurogenic bladder?
Neurogenic bladder is an issue where a person may lack bladder control due to a condition in the brain, spinal cord, or nerve. When a person with this condition have an over-active bladder, symptoms include: having to urinate too often in small amounts, problems emptying all the urine from the bladder, and loss of bladder control. On the other hand, when a person with this condition have an under-active bladder, symptoms may include bladder becoming too full and may leak urine, inability to tell when the bladder is full, problems starting to urinate or emptying all the urine from the bladder, and urinary retention.
