猝死是原来健康者或看似健康者,或已处于疾病康复期,没有任何死亡迹象,于6 h内,自然发生、出乎意料的突然死亡。有研究报道[1],精神病患者每年猝死发生率为11.6/万。精神病患者猝死更多发生于夜间,此时医务人员少且警觉性低,往往晨起时被发现已经死亡。由此可能带来严重医疗纠纷和巨额经济赔偿。如何评估和预测精神病患者的夜间猝死风险,及早发现高危患者,早期护理干预和及时通知医师,非常重要,可以避免部分患者的意外死亡。本文 Sudden death, a healthy or seemingly healthy person, or already in the convalescence of the disease without any signs of death, occurred spontaneously and unexpectedly within 6 hours of sudden death.

Sudden death from mental illness occurred more often during the night, when medical personnel were less alert and less likely to be found dead early in the morning. This may lead to serious medical disputes and huge financial damages. How to assess and predict the risk of sudden death at night in patients with psychosis, early detection of high-risk patients, early nursing interventions and timely notification to physicians is very important to avoid the accidental death of some patients.
