The disorders of cardiac and pulmonary function as complications of scoliosis, have been described by numerous investigators since Hippocrates. The abnormalities of respiratory and cardiovascular function in scoliosis include reduced lung volume and compliance of the total respiratory system, arterial hypoxemia, which may be associated with hypercapnia, impaired chemical regulation of ventilation and increased pulmonary vascular resistance. We recently had experienced of two cases of severe scoliosis of Cesarean section (onse was a severe kyphoscoliotic patient) in Eul Zi Hospital, and was anesthetized with halothane or ethrane. The following conclusions were observed: 1) Arterial blood gas must be checked serially. 2) Anesthesiologists must know the degree of abnormality of the spine and the cardiopulmonary dysfunction. 3) During anesthesia, intermittent positive pressure breatheing(IPPB) or positive end expiratory pressure(PEEP) is needed for good oxygenation. 4) Intubation tube length and tube location are very important. 5) For treatment of postoperative complications, digitalization, bronchodilators, and mechanical ventilation may be needed.
