Abstract

Pressure-limit ventilators are used because it is believed that they decrease the incidence of pulmonary gas leaks and chronic lung disease. The disadvantage of pressurelimit ventilators is that there is no automatic compensation for changes in compliance and resistance of the lung and the chest wall. Consequently, if lung compliance decreases, tidal volume will decrease and blood gases will worsen. The aim of this study is to find the adequacy for the oxygenation and ventilation of volume-limit ventilator with pressure-limit control accessary in pediatric patient with congenital heart disease. The pressure-limit control accessary for anesthetic ventilator(AV-E, North America Drager, Bedford, USA) in 36 pediatric patients undertaken open heart surgery and thoracotomy, retrospectively, were employed. The patients were divided into 3 groups according to their body weights. The respiratory rate of group I (<5 kg, n=12) was 25/min, group II(> or = 5, <10 kg, n=6) was 20/min and group III(> or = 10, < 20 kg, n=8) was 15/min. The patients were divided into another 2 groups, A(n=30) or B(n=6), with the supine or lateral, respectively according to the operation position. The results showed all the values of arterial blood gases almost within normal limits, except one patient in each group. We concluded that anesthetic Drager infant ventilator with pressure-limit control accessary was useful during controlled ventilation, and this is suitable for the prolonged operation in pediatric patients with the supine or lateral position.
