Filter by:This clinical trial is being conducted to study lung function and movement of the major muscle involved in breathing (the diaphragm) after a brachial plexus nerve block (nerve "freezing"). The purpose of this study is to find out what effects (good and bad) ultrasound guided nerve freezing has on the movement of the patient's diaphragm and their lung function. The potential advantage of ultrasound guidance will be a lesser chance of freezing the nerves that innervate the diaphragm and thus having less of an effect on lung function.
Diaphragm paralysis is a possible complication of cardiac surgery. The spontaneous recovery of the diaphragm mobility is slow and partial or absent in most cases. We hypothesize that a program of diaphragm muscle training by means of the Threshold variable resistance device could improve the rate of complete diaphragm mobility recovery in a shorter time period. Patient with post-cardiosurgical diaphragm paralysis will be random assigned to the specific training protocol or to a generic non-training physical activity.
