Gastric Sonography in the Fasted Surgical Patient

Prevalence and prediction of higher estimated gastric content in parturients at full cervical dilatation: A prospective cohort study

“…As previously reported in the adult pregnant and nonpregnant population, there was a significant relationship between the qualitative antral grade and the calculated gastric volume, with a significant increase in gastric fluid volume along with the qualitative grading scale . Nonetheless, although the qualitative ultrasound grading system may be useful to predict the gastric fluid volume and, therefore, could help differentiate between low and high gastric volume states, our results corroborate those of previous works showing that some patients with a grade 2 antrum may have gastric fluid volume <1.5 mL/kg and, conversely, some patients with a grade 1 antrum may have gastric fluid volume >1.5 mL/kg .…”

“…Conversely, parturients were considered as having lower estimated gastric content in the absence of any solid content in both positions and when the calculated gastric fluid volume was <1.5 mL/kg. In addition, based on the qualitative assessment of the antrum described by Perlas et al, patients were classified into three grades: grade 0 was defined as the absence of any content in the antrum in both the semirecumbent and the semirecumbent‐right lateral positions; grade 1 as any fluid content seen in the antrum in the semirecumbent‐right lateral position only; grade 2 as any fluid content observed in both the semirecumbent‐right lateral and the semirecumbent positions.…”

Ultrasound assessment of gastric emptying after breakfast in healthy preschool children

“…Most frequently, ultrasonography was used for indirect assessment of gastric volume by measurement of the cross‐sectional area of the gastric antrum. In the beginning, this technique was evaluated in adults, and later on also in pediatric patients . All studies found a significant correlation between the gastric antral area and the gastric volume suctioned via a gastric tube or endoscope or measured using magnetic resonance imaging.…”

Evaluation of gastric residual volume in fasting diabetic patients using gastric ultrasound

“…Qualitative grading for assessment of gastric antrum: three point grading was evaluated as follows: Grade 0: Empty antrum, Grade 1: minimal fluid detected in right lateral position only, and Grade 2: distended antrum in both semi‐sitting and right lateral positions.…”

“…Thus, no special concern for diabetic patients is mentioned in the current guidelines for preoperative fasting for elective surgery . Gastric ultrasound had become increasingly used for evaluation of gastric contents in various types of patients; however, it has not been previously used for evaluation of the gastric residual volume in diabetic patients scheduled for elective surgery. The aim of our study is to evaluate gastric residual volume in diabetic patients versus healthy controls scheduled for elective surgery, using gastric ultrasound.…”
