A functional classification of respiratory compromise in spinal cord injury.

Spinal cord injury (SCI) patients have unique care needs, particularly related to the respiratory system. Respiratory problems now comprise a major cause of death in the acute and chronic phases of SCI, especially among quadriplegics. Previous literature has analyzed respiratory muscle dysfunction in SCI according to neurologic levels of injury (Alvarez, Peterson & Lunsford, 1981; McMichan, Michel & Westbrook, 1980). In general, the higher the level of injury, the greater the respiratory compromise and need for ventilatory assistance. Although level of injury is significant, it cannot be used as the sole determinant of respiratory compromise. For example, a 25 year old C4 quadriplegic with an intact diaphragm might have less respiratory impairment than a 60 year old C6 quadriplegic with CHF and a history of COPD. A new classification of SCI patients according to amount of respiratory compromise was developed by our team at the Spinal Cord Injury Unit at the Palo Alto VA Medical Center. The patient is scored in three categories: 1) level of injury; 2) completeness of injury; and 3) associating factors, i.e. age, preinjury chronic lung disease. The purpose of this grouping is to better predict the amount of ventilatory impairment in SCI patients. Used during the initial assessment, patients at high risk for impairment could be determined and optimal respiratory care initiated. This classification can also be used as a clinical nursing tool. Using this scoring system, the nurse could anticipate the patient's respiratory needs, i.e. suctioning, chest physiotherapy, oxygen, hydration, nutritional support and teaching of patient and family in order to comprehensively plan and implement care.(ABSTRACT TRUNCATED AT 250 WORDS)
