Abstract

Background : Extubation failure and reintubation increase the morbidity and the mortality rate. Several extubation criteria and risk factors for extubation failure have been recommended. However, some patients present with extubation failure even after a planned extubation. The aim of this study was to evaluate the clinical characteristics of patients with extubation failure after a planned extubation. Methods : Thirty one patients who presented with planned extubation were included. Extubation failure was defined as reintubation within 48 hours after extubation. The clinical, respiratory and hemodynamic parameters between extubation success and failure group were compared. Results : Six patients were included in the failure group. The extubation failure rate was 19.4%. The age, periods of intubation and heart rates were significantly different between the extubation success and failure group. In the success and failure group, the mean age were $60.4{\pm}15.65$ vs. $80.3{\pm}7.17$ year, the intubation periods were $7.12{\pm}2.47$ vs. $13.83{\pm}2.4$ day and the heart rates were $94.32{\pm}5.77$ vs. $110.67{\pm}3.78/min$, respectively. Conclusion : Old age and patients intubated for periods will require a will careful assessment before extubation. Extensive cardiac evaluations before extubation will also be needed.

배 경 : 기관 내관 발관의 실패와 재 삽관 (extubation failure and reintubation)은 유병률 및 사망률의 증가를 초래하므로 기관 내관을 제거할 때 신중한 평가가 필요하다. 발관 실패의 여러 위험 요인이 제시 되었고 발관의 임상적 기준이 제시되었으나 여전히 일부 환자는 발관 실패를 경험하게 된다. 이에 저자들은 계획된 발관을 시도한 환자를 대상으로 발관 실패 및 재 삽관한 환자의 임상적 특징을 보고자 하였다. 방 법 : 인공 호흡기 치료 후 호전되어, 충분한 발관에 대한 평가를 거쳐 계획된 발관을 시도한 31명의 환자를 대상으로 하였다. 이들 환자 중 발관 48시간 이내에 호흡 부전으로 재 삽관 한 환자를 발관 실패로 정의하였다. 발관 성공 군과 실패 군간의 임상적 지표, 호흡기능 및 혈역학적 지표 등을 비교하였다. 결 과 : 31명의 환자 중 6명이 발관 실패 군이었고, 발관 실패율은 19.4% 였다. 성공 군과 실패 군 간에 나이 (성공군 $60.4{\pm}15.65$, 실패 군 $80.3{\pm}7.17$세), 총 삽관 시간(성공 군 $7.12{\pm}2.47$, 실패 군 $13.83{\pm}2.4$ 일), 분당 심박수 (성공 군 $94.32{\pm}5.77$, 실패 군 $110.67{\pm}3.78$ 회)에서 의미 있는 차이를 보였다. 결 론 : 고령의 환자나 삽관 기간이 길었던 환자는 발관에 신중을 기해야 하며, 발관 전 심장 기능의 적극적인 평가도 필요할 것으로 사료된다.
