Background and Goals: Numerous studies indicate that enteral nutrition is superior to that of parenteral (1). The frequency of enteral nutrition-related gastrointestinal complications in critically ill patients is high (2). Enteral nutrition (Gavage) has complications such as diarrhea, nausea, vomiting and gavage intolerance (the residual volume of that which is aspirated from stomach is greater than 50% of the volume that is infused), which may cause fluid and electrolyte imbalance. The goal of this study was comparison of the above complications between bolus, intermittent and continuous methods of gavage in surgical intensive care unit (SICU) patients.

Materials and Methods: After approval of the proposal by the Ethics committee and obtaining the informed consent, this clinical trial study was done on 63 SICU patients. Patients divided in three groups randomly. The methods of gavage that used in three groups were bolus, intermittent and continuous respectively. Data collection was done with a checklist about gavage method and the complication data. Statistical analysis was performed with ANOVA and determination of Pearson correlation coefficient.

Results: The study showed that the incidence of diarrhea, nausea, and vomiting didn't have any significant difference in three groups. Data about gavage tolerance are shown in table:

Conclusions: This study showed that continuous method of gavage in SICU patients is better tolerated than bolus method.
