초록

목적: 본 연구의 목적은 섬망이 있는 말기암환자에 있어 진정제의 투약 투약 관련 특성을 파악하고, 진정제 투약군과 비투약군 간의 생존기간의 차이를 확인하기 위함이다. 방법: 본 연구는 2012년 1월부터 2013년 12월까지 B 광역시 소재 P대학교병원에서 응급실과 수술실, 중환자실을 제외한 병동에서 임종한 암환자 900명 중 경과기록지, 간호기록지를 통해 섬망선별 도구인 Nu-DESC를 이용하여 섬망이 있었던 말기암환자 240명을 대상자로 선정하였다. 투약기록지를 통해 진정제인 haloperidol, diazepam, lorazepam을 정맥 또는 근육주사로 규칙적이거나 필요 시 투여한 횟수를 조사하였다. 결과: 연구 대상자의 섬망기간은 최소 1일에서 최대 61일까지 나타났고, 중앙값은 5일이었다. 연구 대상자에게서 나타난 섬망 특성은 부적절한 행동이 35.0%로 가장 많았다. 연구 대상자의 연령(F=3.96, P=0.021), 원발암의 종류(F=3.31, P=0.010), 항암치료 여부(t=-3.44, P=0.001)에 따른 섬망기간이 유의한 차이가 있었다. 연구 대상자가 진정제를 복용한 경우는 72.1%이었고, 투약된 진정제의 종류는 haloperidol이 59.6%로 가장 많았다. 진정제 투약군의 생존기간은 평균 16.85일, 비투약군은 9.37일로 나타났으나 이는 통계적으로 유의하지는 않아(t=1.766, P=0.079) 진정제 투약이 생존기간에 영향을 미치지는 않았다. 결론: 말기암환자의 섬망 발생 시 진정제 투약이 생존기간에 미치지 않았다. 이러한 결과를 바탕으로 생명단축의 윤리적 문제로 인해 진정제 사용을 꺼려하기 보다는 증상완화를 위한 진정제 치료를 적극적으로 권유할 수 있다. 또한 섬망은 가족이나 의료진과의 의사소통 장애를 유발할 뿐 아니라 환자나 가족들에게 스트레스로 작용하며 돌봄에 대한 부담감을 가중시키므로, 적절한 진정제의 투여는 말기암환자와 가족의 안위를 위해 적극적으로 추천하는 바이다.

Purpose: This study analyzed the difference in survival time of patients with delirium according to sedative medication. Methods: From January 2012 through December 2013, a retrospective cohort study was performed using the electronic medical records (EMR) of Pusan National University Hospital. Among 900 patients who died from cancer, we selected 240 who suffered delirium based on the EMR. The Nu-DESC delirium screening test was used to diagnose delirium. Results: The median length of delirium period was five days. Delirium characteristics were dominated by inappropriate behaviors (35.0%). Sedatives were administered in 72.1% of the cases. The most frequently used sedative was haloperidol which was used in 59.6% of cases. The delirium period significantly differed by patients' age (F=3.96, P=0.021), cancer type (F=3.31, P=0.010), chemotherapy (t=-3.44 P=0.001). The average survival time was 16.85 days for the sedative medication group and 9.37 days for the non-medication group, which, however, was not significant (t=1.766, P=0.079). Conclusion: In this study, the use of sedatives did not affect patients' survival time. Thus, appropriate sedative medication can be positively recommended to comfort terminal cancer patients and their families.
