Abstract:
Objective:To study the feasibility of using bedside ultrasound in evaluating gastric residual volume in critical ill patients with enteral nutrition support.Methods:From May 2019 to August 2019, 60 patients were selected to receive enteral nutrition via gastric tube in ICU of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. Patients were divided into the experimental group and the control group according to the odd and even number of beds, 30 patients in the experimental group with odd number of beds and 30 patients in the control group with even number of beds. Gastric residual volume was evaluated at 0, 4, 8, 12, 16, 20, 24 h of enteral nutrition. In the experimental group, the gastric residual volume was evaluated by bedside ultrasound and syringe suction at each time point. In the control group, only bedside ultrasound was used to evaluate gastric residual volume. The results of operation time, monitoring results at different time points, diarrhea and the utilization rate of gastrointestinal motility drugs target feeding time, vomiting, were compared between the two groups.Results:There was no statistical difference between the gastric residual amount monitored by ultrasound and the gastric residual amount monitored by suction ( P>0.05). The operating time of bedside ultrasound monitoring was (62.40 ± 4.00) s, the operating time of suction monitoring was (78.39 ± 12.15) s, and the operating time of bedside ultrasound monitoring was less than that of suction ( t value was 6.633, P<0.01). There was no significant difference in the rate of vomiting, diarrhea and gastrointestinal motility drugs between the two groups( P>0.05). The time to reach the target feeding amount in the control group was (3.04 ± 0.31) d, and the time to reach the target feeding amount in the experimental group was (4.19 ± 0.33) d. The time to reach the target feeding amount in the control group was less than that in the experimental group ( t value was 13.42, P<0.01). Conclusions:Bedside ultrasound can be used to evaluate the residual gastric volume of enteral nutrition support patients, guide the implementation of enteral nutrition, shorten the operation time, reduce the workload of nurses, and avoid the contamination of enteral nutrition preparation.
