Delirium has become better studied, but is still only partially understood and significantly underestimated. There are some well-known risk factors, but little is known about the incidence of delirium in the diverse patient population of a post anesthesia care unit (PACU). The aim of this study was to investigate the presence of delirium using the Nursing Delirium Screening Scale (NU-DESC).
1000 consecutive patients in the PACU were prospectively evaluated at the point when being ready to be transferred to the normal ward by the registered nurses of the PACU.
The data of 1,000 patients was recorded. 242 of the patients (24.2%) were preoperatively classified as ASA I physical status, 664 patients (66.4%) as ASA II. A total of 43 patients (4.3%) presented with a delirium at the time point where they would have been transferred to the normal ward (138.4 ± 55.2 min after arrival in the PACU). 287 patients (28.7%) of the entire group were over the age of 70 years. Considering only this subgroup, delirium was diagnosed in 30 individuals (10.5%).
Delirium screening with the NU-DESC, collected by nursing staff of a PACU is easily feasible and demonstrated a low incidence of delirium in the presented setting.

谵妄已得到更好的研究，但仍仅被部分理解且被严重低估。存在一些众所周知的风险因素，但对于麻醉后护理单元（PACU）中不同患者群体的谵妄发生率知之甚少。本研究的目的是使用护理谵妄筛查量表（NU-DESC）调查谵妄的存在情况。
PACU的注册护士在1000例连续入住PACU的患者准备转至普通病房时对其进行前瞻性评估。
记录了1000例患者的数据。242例患者（24.2%）术前被分类为ASA I身体状况，664例患者（66.4%）为ASA II。共有43例患者（4.3%）在准备转至普通病房的时间点出现谵妄（到达PACU后138.4±55.2分钟）。整个组中有287例患者（28.7%）年龄超过70岁。仅考虑这个亚组，30例个体（10.5%）被诊断为谵妄。
由PACU护理人员使用NU-DESC进行谵妄筛查很容易实施，并且在所呈现的环境中谵妄发生率较低。
