  6. 4. Tactile touch in intensive care : Nurses' preparation, patients' experiences and the effect on stress parameters

    Author : Maria Henricson; Bengt Fridlund; Kerstin Segesten; Anna-Lena Berglund; Sylvia Määttä; Karlstads universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tactile touch; intensive care; stress; oxytocin; complementary method; nursing; preparation; randomised controlled trial; comfort; lifeworld research; narratives; Nursing; Omvårdnad; Nursing Science; Omvårdnad;

    Abstract : Aim: The overall aim of this thesis was to acquire knowledge about whether tactile touch as a complementary method can (i) promote comfort and (ii) reduce stress reactions during care in an intensive care unit (ICU) Method: In Paper I, five nurses with a touch therapist training were interviewed about their experiences of preparation before giving tactile touch in an ICU. To analyse the meaning of preparation as a phenomenon, Giorgi’s descriptive phenomenological approach was used. READ MORE
