SPINAL CORD INJURIES
| Question | Answer |
|---|---|
| Most common levels of injury in spinal cord | C5-C7, T12, L1 |
| Type of spinal cord injury where there is complete motor and sensory dysfnx | Complete |
| Type of spinal cord injury where there is still motor and sensory fnx remains | Incomplete |
| Type of complete spinal cord syndrome if patient manifests quadriplegia, dyspnea, & bladder and bowel dysfnx | Cervical |
| Cervical spine consists of | C1-C8 |
| Which part of spinal cord that causes dyspnea because it primarily affects the diaphragm | C3-C5 |
| Which part of spinal cord forms the phrenic nerve | C3-C5 |
| Which part of spinal cord affects the bladder and bowel | S2-S4 |
| Type of complete spinal cord syndrome if patient manifests paraplegia, dyspnea and affects abdominal muscles and bladder and bowel | Thoracic |
| Dyspnea in thoracic is primarily caused by which spinal cord | T1-T6 |
| Dysfnx in abd. Muscle in thoracic complete SCI is caused by which spinal cord level | T7-T12 |
| Cut off for autonomic dysreflexia is in which spinal cord level | T6&above |
| Which part of spinal cord affects lower extremities | Lumbar/sacral |
| Complication of spinal cord injury where there is temporary loss of all reflexes below the injury | Spinal shock |
| Spinal shock manifests when | Days to weeks |
| S/sx of spinal shock mostly focuses on | Paralysis and loss of sensation |
| Complication of spinal cord injury where there is loss of sympathetic tone | Neurogenic shock |
| Where is the injjury in Neurogenic shock | T6& above |
| Triad signs of Neurogenic shock | BHW Bradycardia, Hypotension, warm/dry skin |
| Mgt in Neurogenic shock to preserve spinal cord perfusion | Maintain MAP of >/= 85 |
| Complication in SCI where there is massive sympa response r/t stimulus below the injury | Autonomic dysreflexia |
| Injury in Autonomic dysreflexia | T6 & above |
| Triggers for Autonomic dysreflexia | Full bladder Fecal impaction Tight clothing Skin irritation |
| S/sx of Autonomic dysreflexia | Hypertension, bradycardia |
| S/sx of Autonomic dysreflexia above the injury | Flushing, sweating, nasal congestion |
| S/sx of Autonomic dysreflexia below the injury | Pale cool skin |
| Position if pt. Has Autonomic dysreflexia | Sit upright/high fowlers |
| Management in Autonomic dysreflexia | Assess the cause & remove stimulus |
| How to manage bladder distention | Crede's maneuver |
| Ascending tract of spinal cord is primarily | Sensory |
| Descending tract of spinal cord is primarily | motor |
| Spinal cord part mainly for sensory | Dorsal column, lateral spinothalamic, ventral spinothalamic |
| Spinal cord part associated with fine touch, vibration, and proprioception | Dorsal column |
| Spinal cord part associated with pain and temperature | Lateral spinothalamic |
| Spinal cord part associated with crude/light touch | Ventral spinothalamic |
| Spinal cord part mainly for motor | Ventral & lateral corticospinal |
| Spinal cord part associated with limb mov't | lateral corticospinal |
| Spinal cord part associated with neck/trunk mov't | Ventral corticospinal |
| What is the most common incomplete SCI | Central cord syndrome |
| Central cord syndrome cause is | Hyperextension of neck |
| Central cord syndrome is common on | Elderly |
| Central cord syndrome main symptoms primarily focuses on | Weak arms > legs |
| Characteristics of sensory loss (pain/temp) in Central cord syndrome | Cape like distribution |
| Anterior cord syndrome 2 main cause is | Flexion injury & ant. Spinal artery occlusion |
| S/sx of Anterior cord syndrome | Motor and sensory loss |
| How is Anterior cord syndrome different from the rest of incomplete SCI | Intact proprioception & vibration |
| Type of incomplete SCI where the cause is d/t hemisection stab wound, gunshot wound | Lateral cord syndrome |
| Lateral cord syndrome is aka | Brow sequard syndrome |
| S/sx in Lateral cord syndrome that is ipsilateral | Motor loss, vibration & proprioception loss |
| S/sx in Lateral cord syndrome that is contralateral | Pain and temp (If right ang affected, left ang naay sensory loss |
| Type of incomplete SCI where the cause is d/t Vitamin B12 syndrome | Posterior |
| Posterior cord syndrome causes aside from Vitamin B12 syndrome | Tabes dorsalis, trauma |
| S/sx in Posterior cord syndrome | Loss in vibration and proprioception |
| Main intervention for SCI | Neutral alignment & avoid twisting & extension |
