Effectiveness and safety of perioperative enteral feeding in patients with burn injuries: a systematic review...

The objective of this review is to determine whether perioperative enteral feeding improves outcomes in patients with burns.

Literature has identified many positive benefits of nutrition support for patients with burn injuries, including preservation of lean body mass, improved wound healing, reduced gastrointestinal permeability and enhanced immunity. Fasting for surgery can undermine the nutritional care of these patients by causing nutrient deficits. It may also negatively affect patient well-being and insulin resistance. Perioperative fasting is intended to protect patients from regurgitation and pulmonary aspiration. This research aims to investigate whether perioperative feeding impacts outcomes in patients with burn injuries.

This systematic review will consider studies whose participants have a burn injury. The intervention is perioperative enteral feeding (either intragastric or post-pyloric). Patients who received perioperative feeding will be compared with patients who had enteral nutrition withheld during the perioperative period. A number of outcome measures will be investigated, including mortality, length of stay, wound infection, wound healing rate and aspiration pneumonia.

The key databases searched will be PubMed, CINAHL, Embase, Web of Science and Cochrane Central Register of Controlled Trials and Scopus. Only studies published in English will be considered. There will be no date limits. Full texts of selected studies will be retrieved and assessed against inclusion criteria. Studies that do not meet the inclusion criteria will be excluded, with reasons provided. Data synthesis will be pooled in a statistical meta-analysis. Subgroup analysis will be conducted where possible. Where statistical pooling is not possible, the findings will be presented in narrative form.
