简要总结
A recent systematic review reported that the prevalence of enteral nutrition intolerance in critically ill patients ranged from 2% to 75%, and the pooled rate was 38.3%.Many randomized controlled trials have reported that the incidence of pneumonia, regurgitation and aspiration do not correlate well with gastric residual volume (GRV) monitoring. In addition, it was reported that GRV monitoring may cause more frequent obstructions in the enteral tube access, leading to greater loss of time for intensive care unit nurses and patients receiving less than the prescribed daily intake due to enteral nutrition interruptions. The most recent SCCM/ASPEN guidelines in 2016 recommended that GRV monitoring not be included in the daily care protocol, but many institutions still use it to determine whether to continue enteral nutrition or to detect enteral tube-feeding intolerance. This study aimed to evaluate the relationship between ultrasonographic gastric antral measurements and aspirated gastric residual volume GRV in mechanically ventilated critically ill patients receiving enteral tube feeding via nasogastric, orogastric, or percutaneous gastrostomy tubes.
详细描述
Data collection and measurements:
The following clinical parameters of included patients will be recorded: age, sex, body weight, height, body mass index, Acute Physiology and Chronic Health Evaluation II (APACHE II) score on the day of admission,the Charlson Comorbidity Index score, any comorbid diseases, the total amount of EN product during the last 24 hours before ultrasonographic assessment, vasopressor therapy during imaging, and the dose of the vasopressors.
Ultrasonographic gastric antrum imaging procedure:
Ultrasonographic gastric antrum imaging will be carried out by the same intensivist on each patient just before routine tube-feed aspiration. Gastric antrum images will be obtained with a 2.5-6 MHz curvilinear probe placed in the sagittal plane of the epigastric region. All imaging attempts will be carried out in a 30-degree head-elevation supine position as described previously. Reference points will be used to obtain images of the gastric antrum-left anterior lobe of the liver, head of pancreas and abdominal aorta.The anteroposterior and craniocaudal diameters of the gastric antrum will be measured three times for each ultrasonographic assessment. The mean value of the three will be recorded. The universally accepted Two-Diameter Method defined by Bolondi et al. will be used for the measurement of antral cross-sectional area.
Tube-feeding aspiration (GRV measurement) procedure:
