abbreviation for high dependency unit: the part of a hospital that provides a high level of care and treatment for patients who are seriously ill or who have just had a major operation

After some major operations, you may be taken to the HDU or ICU. 大手术之后，可能被送入高依赖病房或者重症监护室。

The absence of an HDU in hospitals taking acute surgical cases was detrimental to patient care. 在接收急诊手术病例的医院中，如果没有高依赖病房，则不利于患者的治疗。
