Abstract

From January, 1992 to June, 1996, )7 patients with flail chest were treated at Sonnchunhyang university hospital. 15 patients were managed by internal fixation of fractured ribs, whereas the remaining 22 patients were managed by endotracheal intubation and intermittent positive-pressure ventilation alone. There were no difference between two groups in age, sex, the severity of injury to the chest wall and the nature of associated injuries. Average dur'Btion of assisted ventilation was 5.7 $\pm$ 1.7 days in the patients treated by internal fixation versus 8.7 $\pm$ 3.3 days In the patients treated by continuous me hanical ventilation. Average stay in the intensive care unit was 8.3 $\pm$ 3.9 days for the patients treated by internal fixation, whereas it was $13.2\pm4.1$ days in the group treated by continuous mechanical ventilation alone. In the group treated by internal fixation, complications were 3 atelectases(20.0%), 1 pneumonia(6.7%), 2 operative wound problems(12.3%) and 1 barotrauma(6.7%). In the other group, 7 atelectases(31.8%), 4 pneumonitis(18.2%), 2 empyemas(9.1%) and 3 barotraumas(1).6%). The mortality rate was 13.3%(2/15) in the surgically treated patients, whereas it was 22.7%(5122) in the other group. The treatment of flail chest by internal fixation resulted in speedy recovery, decreased complications and mortalities, and better ultimatc cosmetic and functional results.

순천향대학교 의과대학 흉부외과학교실에서는 1992년 1월부터 1996년 6월까지 불안정 흉벽손상으로 지속적 인공호흡법의 치료를 받은 22례와 내적 늑골고정 술을 받은 15례를 대상으로 하여 비교분석하였 다. 환자의 나이는 지속적 인공호흡군이 평균 $43.4\pm16.4세었고수술정복군이$ 평균 $40.9\pm13.8세었으$ 며, 성 비는 지속적 인공호흡군이 6.3 : 1, 수술정복군이 6.5 : 1으로 두 군 모두 사회활동이 활발한 30,40 대 남자에서 많은 분포를 보였으며 두 군간에 현저한 차이는 없었다. 늑골골절 수는 지속적 인공호홉군이 평균 $8.7\pm2.3개,$ 수술정복군이 평균 $7.5\pm2.5개로$ 두 군간에는 통계학적 차이가 없었으며(p=0.3129) 동 반된 흉막, 폐장 및 심장의 손상정도가 두 군간에 차이를 보이지 않았다. 인공호흡기의 사용기간은 지속 적 인공호흡군이 $8.7\pm3.3일,$ 수술정복군이 $5.7\pm1.7일으로$ 두 군간에는 통계학적 유의성이 있었으며 (p=0.0134),중환자실의 입원기간은 지속적 인공호흡군이 $13.2\pm4.1일,수술정복군이$ 8.3그3.9일으로두 군간에 의미있는 차이가 있었다(p=0.0175). 합병증은 지속적 인공호흡군이 무기폐 7례(31.8%), 폐렴 4 례(18.2%), 농흉 2례(9.1%) 및 인공호흡과 관련된 합병증 3례(1).6% ; 기흉 2례, 외상후 폐기종 1례)가 있었으며,수술정복군은 무기폐 3례(20.0%),폐렴 1례(6.7%),수술창의 문제 2례(12.3%; 감염 1례,파열 I례) 및 인공호흡과 관련된 기흉 1례(6.7%)가 발생되어 지속적 인공호흡군이 수술정복군보다 합병증의 발생이 많았다 사망은 지속적 인공호흉군이 5명(22.7%),수술정복군이 2명(13.3%)으로 지속적 인공호 흡군에서 사망율이 높았다.
