Patients' experience of being critically ill or severely injured and cared for in an intensive care unit in relation to the ICU syndrome. Part I.

The intensive care unit (ICU) syndrome is regarded principally as a complex interaction of several contributory factors, all of which can be seen as partly responsible for the development of the syndrome. The purpose of this study was to describe and give a deeper insight into patients' experiences and memory recall, both during and after their stay in the ICU. Nineteen patients who had been respirator treated (ventilated), and had stayed at least 36 hours in the ICU, were interviewed about one week after discharge, and again 4-8 weeks after their discharge from the ICU. Patients' experiences are interpreted and related to previous views held concerning the syndrome, together with an awareness of other important and significant phenomena, i.e. a hermeneutic approach. This study partly confirms the findings of earlier studies concerning the ICU syndrome, but also reveals some new aspects, which have not previously been considered. The patients described themselves as experiencing some sort of state of chaos following the onset of their sickness, injury or accident, which resulted in feelings of extreme instability, vulnerability and fear, often experienced as prolonged inner tension. It was reported that even the most trivial events in circumstances or routines could trigger changes-either an increase or decrease-in patients' feelings of fear or inner tension. The caring relationship was perceived as providing an important degree of security and comfort. Nursing care actions can therefore be seen as vital factors in patients overcoming the accompanying horrific experiences to which they can be subjected. This state of chaotic feeling, and how it is combated and treated, appear to be one critical factor in the development and progression of the ICU syndrome.
