Chest physical therapy is now widely used after open heart surgery to prevent secondary pathology in the lungs and to improve the phhysical condition of the patient. A brief overview of cardiac surgery is presented. Factors occurring before, during, and after surgery that contribute to postoperative respiratory insufficiency are outlined, and a comprehensive three-phase treatment program is described. Also, treatment guidelines, precautions, and contraindications are discussed.

Randomized Controlled Trial Clinical Trial
Failure of low dose heparin to prevent pulmonary embolism after hip surgery or above the knee amputation.
In a randomized, double-blind trial, 5,000 USP units of sodium heparin or saline were give subcutaneously at least two hours before surgery and at 12 hour intervals thereafter to patients requiring total hip replacement, surgical correction of hip fracture, or major lower extremity amputation for vascular insufficiency. Lung perfusion scans were performed before surgery and at weekly intervals during the postoperative period. Pulmonary arteriograms were requested in patients developing new perfusion defects on serial scans. ⋯ The incidence of acute pulmonary embolism in 94 patients undergoing above the knee amputation was 25% in patients receiving heparin and 27% in patients receiving saline. The incidence of acute pulmonary embolism in 78 patients undergoing hip surgery was 13% in patients receiving heparin and 12% in patients receiving saline. We conclude that the regimen used had no significant effect on the incidence of acute pulmonary embolism in patients undergoing hip surgery or above the knee amputation.

A retrospective analysis of 123 pediatric tracheostomies reveals an overall complication rate of 33%. Immediate complications were present in 12% or 15 patients. The most frequent immediate complications were pneumomediastinum and pneumothorax. ⋯ Age, underlying disease, and prior endotracheal intubation had a high degree of correlation with complications. The use of a mechanical respirator following tracheostomy did not appear to be significantly related to complications. Fifty percent of the delayed complications in this series were regarded as being unrelated to the tracheostomy or the trachesotomy tube itself.
