共和國後大概1950年尾，普惠醫院護士學校畀華南軍醫防空司令部接收咗，改咗名成防空醫院及護校。到咗1951年教會人士畀逼著走咗，醫院先後改成中國人民解放軍第109醫院同第一七七醫院、第一軍醫大學江村醫院等。普惠醫院原主樓喺1996年畀人清拆咗，剩低護士學校原樓保存到宜家。
At the end of 1950, the Pratt & Whitney Hospital Nursing School was taken over by the South China Military Medical Air Defense Command and renamed the Air Defense Hospital and Nursing School. In 1951, the church members were forced to leave, and the hospital was successively changed to the 109th Hospital and the 177th Hospital of the Chinese People's Liberation Army, and the Jiangcun Hospital of the First Military Medical University. The original main building of Pratt & Whitney Hospital was demolished in 1996, leaving the original building of the nursing school to be preserved to the present day.
