Sun A Chun, Byung Jun Choi, Bo Kyung Cho, Chung Sik Chun, Sung Hoon Cho
Clin Exp Pediatr. 1989;32(11):1553-1559.   Published online November 30, 1989
The development of respiratory management of the newborn has improved the survival rates of respiratory distress syndrome in these two decades. But the incidence of complication associated with this management has been increased. Although the pathogenesis of bronchopulmonary dysplasia has not been clearly established yet, bronchopulmonary dysplasia is one of the major complication of the mechanical ventilation. There are several factors in the development of...
