Summary

The intestine is the most vulnerable target organ in septic patients and is the first to be damaged organ in multiple organ dysfunction syndrome(MODS).Therefore, improving intestinal motility and mucosal barrier function is critical to the treatment of sepsis. Many studies have shown that, early enteral nutrition(EN) in patients with sepsis helps prevent and treat intestinal dysfunction, reducing ICU mortality and length of stay in ICU. However, there is little research on feeding methods. In this study the investigators will compare the outcomes of different feeding methods: continuously-pumped in 24 hours, continuouslypumped in 16 hours and intermittently-pumped through the stomach tube. The aim of this study is to investigate the effects of different feeding methods on intestinal function in septic patients.

Interventions

Type	Name	Description
PROCEDURE	Continuously feeding	Daily amount of feeding were continuously pumped for 24 hours. EN preparation pumping scheme was as follows: The initial pumping speed was average pumping volume of total enteral nutrition in one day, and gastric residual volumes is checked every 4 hours. If it is not tolerable, the speed of the pumping is reduced by half on the original speed. GRV\<200mL were considered markers of good tolerance.Feeding intolerance was defined as GRV\>200 mL. If GRV\>500mL, EN was stopped and reassessed after 4 hours.
PROCEDURE	16-hours feeding	Daily amount of feeding were continuously pumped for 16 hours.EN preparation pumping scheme was as follows: The initial pumping speed was average pumping volume of total enteral nutrition in one day, and gastric residual volumes is checked every 4 hours.If it is not tolerable, the speed of the pumping is reduced by half on the original speed. GRV\<200 mL were considered markers of good tolerance. Feeding intolerance was defined as GRV\>200 mL. If GRV\>500mL, EN was stopped and reassessed after 4 hours.
PROCEDURE	intermittent feeding	Daily amount of feeding were divided into four meals, each meal are pumped within 60mins or 120mins through stomach tube. EN preparation pumping scheme was as follows: If the volume of each meal is less than or equal to 250ml(≤250ml), pump in within 60min, if volume is greater than 250ml(\>250ml), pump in within 120min and gastric residual volumes is checked before each intermittent feeding. If it can be tolerated, the velocity of the pumping can be increased by half of the original speed.If it is not tolerable, the speed of the pumping is reduced by half on the original speed. GRV\<200 mL were considered markers of good tolerance. Feeding intolerance was defined as GRV\>200 mL. If GRV\>500mL, EN was stopped and reassessed after 4 hours.
