On a daily basis critically ill paediatric patients are admitted in the Paediatric Critical Care Unit (PCCU). Some of these paediatric patients require cardiothoracic surgery and is mechanically ventilated post-operatively. Chapter one of this study gives an orientation to this research and explains that in order to prevent ventilator associated complications and high hospitalisation costs, the mechanically ventilated paediatric patient following cardiothoracic surgery should be extubated as soon as he/she is ready. Chapter two is dedicated to the available literature on this topic and indicates that literature on extubation criteria for the mechanically ventilated paediatric patient is minimal. The methodology of this study is discussed in detail in Chapter three. Chapter four gives a detailed explanation of the research findings and the researcher included the developed clinical pathway for the extubation of the paediatric patient following cardiothoracic surgery in a private hospital in Gauteng. The relevant clinical pathway functions as a guideline and evidence-based tool in the PCCU. Lastly Chapter five gives a summary of this study and a few recommendations are made. The researcher has included a personal reflection in this Chapter. / Dissertation (MCur)--University of Pretoria, 2014. / tm2015 / Nursing Science / MCur / Unrestricted
