A retrospective study was undertaken of 175 patients (119 males, 56 females) admitted to the neonatal intensive care unit of Mackay Memorial Hospital during the period of July 1, 1985 to June 30, 1986 who received mechanical ventilation during their stay at the hospital. Upon reviewing the clinical histories of these patients, the complication rate of mechanical ventilation was 31.9%. The percentages of each complication were: pneumothorax 50.0%, pneumomediastinum 5.2%, pulmonary interstitial emphysema 1.7%, atelectasia 13.8%, pneumonia 13.8%, chronic lung disease 13.8%, nasopharyngeal infection 1.7%. Survival rate of these ventilated patients with or without complication was not significant statistically (69.2% vs 65.6%). However, with regard to the hospital course, cases with complication had a significantly longer duration of ventilator usage, hospital stay and oxygen usage than uncomplicated cases. In conclusion, experienced personnel are needed to supervise the use of mechanical ventilation in neonates, and a team of well-trained nurses working in the neonatal intensive care unit are essential to minimize complications.

Persistent pulmonary hypertension of the newborn (PPHN) is one of the most challenging situations in the neonatal intensive care nursery and it is associated with a high mortality rate. Hyperventilation therapy has been recommended as the primary ventilator management during recent decades. The associations of pulmonary barotrauma, chronic lung disease and hearing impairment raised the questions of significant pulmonary and neurological complications with this therapeutic modality. From July 1990 to April 1993, 14 cases of neonatal persistent pulmonary hypertension were treated with nonhyperventilation respiratory therapy at the Chang Gung Memorial Hospital. The goals of this therapy were to attain a pH level between 7.40 and 7.50, a PaO2 level between 60 and 90 mmHg and a PaCO2 level between 30 and 50 mmHg. High peak inflating pressure (> 35 cmH2O) and high ventilator rates (> 60/min) were avoided. The average duration on a ventilator was 6.8 +/- 2.9 days. Four patients had pulmonary barotrauma (29%); three of which were pulmonary interstitial emphysema and one pneumothorax. Three patients died (21%). Only one patient had neurological sequelae. No one had developed chronic lung disease. The non-hyperventilation approach for PPHN may be considered as an alternative ventilator management before starting a more aggressive hyperventilation therapy.

A combination of absence of the pulmonary valve with ventricular septal defect, annular pulmonary stenosis and aneurysm of the pulmonary artery is called "absent pulmonary valve syndrome". Most patients with this condition suffered from severe respiratory symptoms in early infancy. Respiratory failure which is the leading cause of mortality in infants with this syndrome, results from pulmonary emphysema, pulmonary atelectasis or pulmonary infection as a consequence of compression of the bronchus by the pulmonary aneurysm. If these patients can be treated medically to survive beyond one year old, gradual decrease in severity of symptoms is expected. A definite correction in childhood is recommended. Otherwise, palliative operation in infancy has a high mortality rate. This paper reported two cases with severe symptoms in infancy; one patient expired at nine months of age, and the other lived beyond one year to receive surgical correction at the age of three. The etiology, clinical features and treatment of absent pulmonary valve syndrome are also discussed.
