Study ObjectiveTo evaluate the gastric contents and gastric residual volume in patient with end-stage renal failure by gastric ultrasound.DesignProspective observational study.SettingTertiary care teaching hospital.PatientsAdults of either gender with BMI < 40 kg/m2 with end-stage renal failure scheduled to undergo arteriovenous graft or fistula.Interventions & MeasurementsThe cross-sectional area of the gastric antrum was measured by gastric ultrasound with patient in both supine and right lateral decubitus positions. The volume of the gastric contents were calculated using suitable validated formula. In addition, the nature of the gastric contents was also determined by gastric ultrasound.Main ResultsThe incidence of delayed gastric emptying was found to be 57.7% in the population studied despite following the prescribed preoperative standard fasting guidelines.ConclusionsThere is a high incidence of delayed gastric emptying in patients with end-stage renal failure presenting for surgery which may predispose them to risk of pulmonary aspiration perioperatively.Copyright © 2024 Elsevier Inc.
