Pulmonary Complications of Acute Spinal Cord Injuries

Abstract

Abstract The records of 123 consecutive patients admitted with spinal cord injury were examined for the presence of pulmonary complications. Forty-nine had tetraplegia and 23 had paraplegia; the remainder suffered a variety of neurological deficits. Multiple injuries were encountered in 36 patients. Fifty-three pulmonary complications were noted in 44 (35.7%) patients. The most common problems were atelectasis and pneumonia. There were 22 (18%) deaths. Fourteen deaths were related to pulmonary complications. The mean age of patients who died was 52 ± 13 (SE) compared to 28 ± 12 for survivors. A mean forced vital capacity (FVC) of 1127 ± 410 cc in patients suffering respiratory difficulties compared to a FVC of 1865 ± 85 cc in patients without complications (P < 0.001). Oxygenation (PaO2 90 ± 19 torr) was normal in patients without respiratory problems and was abnormal in patients developing problems (PaO2 76 ± 30 torr; P < 0.05). Twenty patients were treated with a rotating bed. The complication rate of patients on the bed was only 10%. In conclusion, respiratory problems remain a significant cause of morbidity and mortality in spinal cord injury. The forced vital capacity, blood oxygen tension, and age are predictors of pulmonary complications. The use of a multidisciplinary approach and a rotating bed may minimize these problems.
