Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Comparison of the effects of bolus, intermittent and continuous enteral feeding techniques on plasma glucose level and enteral feeding intolerance in adult intensive care unit patients with sepsis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

in this prospective, controlled trial the main aim is to evaluate the effects of bolus, intermittent and continuous enteral feeding techniques on plasma glucose level in intensive care patients with sepsis diagnosis and to determine whether they are superior to each other in providing norma-glycemia. The secondary aim is to determine the effect of these 3 different enteral feeding techniques on enteral feeding intolerance.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

If the patients were diagnosed with sepsis in ICU, they were not fed after 24:00, and if the gastric residual measured at 05:00 in the morning was negative, they were included in the study. The patients were examined in 3 groups. The number of samples required to be taken in the power analysis performed (G\*power 3.1) was found to be 93 (31 patients in each group) (power value 0.80, alpha error probability=0.05). Patients for the groups were randomly selected by the closed envelope method. A total of 93 envelopes, 31 for each group, were prepared. When the patient was diagnosed with sepsis, if he/she met the inclusion criteria, a random envelope was selected to determine the patient's group. After inclusion in the study, a closed envelope was added again for the patients who should be excluded from the study.
Primary Study Purpose

SCREENING

Blinding Strategy

DOUBLE

Participants Outcome Assessors
Limitation of the study; since the patients were intubated and under sedation, they did not know the diet applied to them, but the physician/nurse who examined the residue and PGD knew the diet. Unfortunately, the person who evaluated these two parameters could not be blinded, as it would not be possible to give without showing the feeding methods. However, groups 1-2-3 were reported to the statistician who analyzed the data. The feeding methods of the groups was not reported.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

bolus feeding group

bolus feeding method;The amount of food to be given for 24 hours calculated for the patient was given as 4 equal amounts for 40 minutes at 4 different times. Starting with 150 cc, the target calorie was reached by increasing 100 cc according to the intolerance before the next feeding hour.

Group Type EXPERIMENTAL

enteral feeding

Intervention Type OTHER

The amount of enteral nutrition that should be given daily was calculated by the nutritionist using the Harris-Benedict formula. Formula at room temperature was given with a nasogastric foley catheter and a feeding pump. The position of the nasogastric Foley catheter in the stomach was confirmed by the PAAC graph when it was first inserted, and by listening before each feeding. Feeding was done in a position with the head at 30 degrees.

blood glucose measurements

Intervention Type PROCEDURE

Blood glucose values were measured in all groups at 06:00, 12:00, 18:00 and 24:00, 4 times a day for 7 days. The sample was taken from the patient's cannula and examined in the biochemistry lab. The targeted range in the measurements was accepted as 70-180 mg/dl.

Evaluation of feeding intolerance with gastric residue

Intervention Type PROCEDURE

gastric residue assessment; 30 minutes after the feeding was stopped, the N/G tube was drained and the amount coming 30 minutes later was evaluated. Residue positive was defined as the return of more than half of the amount of formula in the last cycle. The same was continued without increasing the amount given. If the incoming amount was less than half, the residue was evaluated as negative and the formula was continued by increasing the predetermined amount.

intermittent feeding group

The formula was started as 40 cc/h continuous infusion. It was interrupted after 5 hours. 30 minutes after the break, PGD was measured and intolerance was checked, and if the residue was negative, it was increased by 40 cc. The amount was increased until reaching the amount of formula that should be given for 24 hours calculated for the patient. This cycle was repeated 3 times in 24 hours. At 24:00, it was stopped and feeding was interrupted between 24:00 and 06:00.

continous feeding group

The same method was applied as in Group 2. However, after 24:00, feeding was not interrupted and continued as the 4th cycle.
