ORIGINAL ARTICLEA review of the nursing care of enteral feeding tubes in critically ill adults: part II
Introduction
Critically ill patients commonly have enteral tubes in situ for gastric decompression, delivery of medications and food substitutes. It is essential that critical care nurses use best practice that includes current evidence-based knowledge and skills to care for these patients. To facilitate the benefits and minimise the harm associated with any therapy, nursing practice should be based on the highest levels of evidence. The systematic and rigorous approach to the analysis and grading of research findings in terms of level of evidence facilitates the development of specific guidelines, standards and recommendations to provide the best possible care for every patient. There is, however, limited high level evidence supporting nursing practice of critically ill patients with enteral tubes. In part 1 of this paper, the current research findings for the nursing care of critically ill patients with enteral feeding tubes was reviewed. Nursing care to prevent aspiration was discussed. This paper describes enteral tube management and recommendations for implementing evidence-based protocols for tube and feeding management.

Data sources and levels of evidence
Several methods were used to identify relevant articles for this review. A computerised literature search of online databases MEDLINE (1966–2003), EMBASE (1966–2003), CINAHL (1982–1996), and the Cochrane Library (1992–2003) was conducted. Searches were restricted to the English language, adults and humans. Relevant abstracts were reviewed and identified articles assessed. The reference lists of all articles were examined for additional papers not previously identified. The evidence base applied
Nursing care of patients with enteral tubes used for feeding
Nursing care of critically ill patients with enteral tubes used for feeding should facilitate feeding, promote patient comfort and minimise complications. Safety issues include verification of tube position and ensuring tube patency to minimise the risk of aspiration (The Joanna Briggs Institute, 2002).
Recommendations for nursing practice
Nursing care of critically ill patients should be based on the best available current evidence. It is widely acknowledged when making therapy decisions the hierarchy of evidence, which recognises the pre-eminence of the systematic review and RCT is clearly appropriate (The Joanna Briggs Institute, 2002). However, other qualitative study methodologies can be more helpful in assessing patient feelings and behaviours in relation to therapeutic decisions. It is important nurses are cognisant of
Conclusion
Nursing care should focus on maximising benefits and minimising the risks of enteral tubes and nutrition. When caring for critically ill patients with enteral tubes used for feeding minimising the use of medications that impair gastric emptying such as sedation, minimising interruption of feeding and accepting higher gastric residual volumes, elevating the head of the bed and administering prokinetics are effective nursing strategies supported by a high level of evidence.

The data were collected using a questionnaire developed by the researchers based on the literature (Ayas et al., 2006; Bastin et al., 2004; Commisso et al., 2000; McClurg et al., 2011; Montejo, 1999; Pancorbo-Hidalgo et al., 2001; Preece, 2002; Uysal et al., 2012; Williams and Leslie, 2004, 2005).

Should gastric aspirate be discarded or retained when gastric residual volume is removed from gastric tubes?
2010, Australian Critical CareCitation Excerpt :Performing some statistical modelling may have enhanced understanding of the outcomes of the study. There is a wide variation in the management of GRV and little available evidence to guide practice.5 The volume of GRV considered excessive and the ideal frequency of checking GRV have not been established.
