Effects of continuous positive airway pressure on lung mechanics of babies after operation for congenital heart disease.

The effect of continuous positive airway pressure (CPAP) on lung mechanics was investigated in 12 babies after operation for severe congenital heart disease. At the time of study all babies were receiving or being weaned from ventilatory support and had abnormally low lung volume or compliance. During CPAP there was a fall in the pulmonary resistance which, with a slight decrease in minute ventilation, resulted in a significant decrease in the work of breathing. It is suggested that lowering the oxygen cost of breathing may contribute to the improvement in arterial oxygenation seen when CPAP is used.

Repair of an osteochondral tumor of the talus utilizing a fresh-frozen cadaveric graft.

A case involving a benign osteochondral tumor of the talar dome is presented. Graft considerations are reviewed and some of their specific characteristics are highlighted. Selection of a fresh-frozen cadaveric graft in this case was based on the goal of maintaining articular congruity in the ankle joint. The authors' experience demonstrated that normal joint function can be preserved with this type of graft.

Aneurysmal bone cyst of the second metatarsal.

Aneurysmal bone cyst of the second metatarsal has infrequently been reported in the literature. Its characteristics can mimic various other bone tumors. While radiographic appearance usually typifies this lesion, microscopic evaluation is paramount for a definitive diagnosis. There are various treatment alternatives for this lesion depending on size, the patient's age and radiographic appearance. After evaluating the patient's age and size of lesion in their case study, the authors recommended total excision of the bone cyst with autogenous grafting. The need for rigid external fixation was emphasized. These factors combined to produce satisfactory results in this case study that involved over 2 years of postoperative evaluation.

The management of respiratory failure in paediatrics.

Following a discussion on the most frequent causes of respiratory failure in children and the principles of its treatment the author presents methods of preventing the complications of prolonged endotracheal intubation and tracheostomy performed on special indications. Particular attention has been paid to careful nursing and adequate humidification of respiratory gases. Moreover the avoiding of tightly-fitting endotracheal tubes and the method of their fixation -- as established at the author's hospital -- are of basic importance for the maintenance of uncomplicated intubation for even several weeks. In the treatment of respiratory failure the use of CPAP and PEEP is helpful. An exact knowledge of the mechanics of respiration in children and its correct evaluation are of greater significance when using various methods of controlled respiration than a selection of a respirator model.
