My department had two death cases l

My department had two death cases last week, it's so terrible experience.It happenned too fast, i feel calm now so can tell you. One is suicide, a woman 58 yearsold, she went to the wc in her room to take a bath , and she used her shirt to tie a knot on shower head,put on her neck...it's at night so there were 4 nurses in my department, they try to give first aid to casualties but unable to rescue her from death. Psychiatrist who was responsible for her medical treatment, didnt screen patient's suicide idea.the patient was also still happy and talk with others before she died. The second case which was sudden death, she's suffered a heart attack. We have to held a meeting to write ourself criticisms tomorrow for all the collegues in my department with the attend of the general director, vice general director, some heads of other departments. For the purpose of evaluation and learning by experience. Some my colleagues who have to be directly responsible for two suicide patients, are stressful so much. I'm a team leader of medical treatment room so I need to arrange the meeting with my department director. One nurse need to set her mistake herself for the suicide case despite of the fault is concern with psychiatrist. My director told that they need one has to stand like a gun fodder..I'm so sad, but dont know how to help my colleague. Hope anything will be alright with her..and wish no more patients will be committed suicide successfull.
