[Consequences of adult brachial plexus paralysis and its surgical treatment on respiratory function].
The authors have studied 22 patients suffering from traumatic brachial plexus injuries and the consequences on respiratory function of paralysis of the diaphragm and other respiratory muscles. They have also studied the effects of some surgical treatment on respiratory function. The patients were divided into three groups: post-traumatic paralysis of the diaphragm (5 cases), patients who had had an intercostal neurotization (11 cases) and patients with paralysis of some respiratory muscles with an intact diaphragm (2 cases). Six tests were performed--vital capacity, total pulmonary capacity, residual functional capacity, airway resistance, maximum expiratory volume per second and airflow at 50 p. 100 of the vital capacity. Respiratory function was decreased by about 50 p. 100 in cases of diaphragmatic paralysis. This finding should be taken into consideration in cases of extensive lesions of the brachial plexus. The effects of intercostal neurotization were minimal when performed in cases with respiratory paralysis, but with an intact diaphragm. They were negligible in the absence of any respiratory paralysis. It is concluded that intercostal neurotization should not be performed in cases with diaphragmatic paralysis. In such cases, other types of neurotization are preferred.
