Comparison of the Effect of Enteral Feeding through the Bolus and Continuous Methods on Serum Phosphorus and Glucose Levels in Patients with Mechanical Ventilation: A Randomized Clinical Trial.

The serum phosphorus level was significantly increased in the intervention group (P=0.004) and in the control group (P < 0.001) and was compared with the previous intervention. No significant difference was found between the intervention and control groups before and after the intervention (P=0.22) and also one week after the intervention (P=0.14). There was also no significant difference between the glucose levels from day 1 to day 7 in the control group (P=0.33) and the intervention group (P=0.086). Discussion. Nutritional support in both bolus and continuous methods increased the serum phosphorus level. It indicates the importance of the nutritional method in controlling the phosphorus level in critically ill patients. However, there was no difference between the effects of dietary methods on blood glucose control.
