Abstract
Introduction: Cataract surgery is the most commonly performed ophthalmologic procedure worldwide, and the disease is one of the main causes of reversible blindness worldwide. Objective: To analyze the ultrasound evaluation of gastric contents in patients undergoing cataract surgery. Methodology: Series report evaluating 24 patients in the perioperative period at the bedside using ultrasound to investigate the presence of gastric content that could indicate the risk of aspiration or other anesthetic complications. Results: Thus, 16 patients (66.6%) were female, and 8 (33.3%) were male. The mean age observed was 66.4 years (42-80). The average fasting time was 13 hours and 6 minutes, with the shortest fasting time at 7 hours and the longest at 24 hours. The mean residual gastric volume was 43.7 mL, with a minimum of 0 mL and a maximum of 138.9 mL. Conclusion: The substantial variance in gastric volumes assessed in the study underscores the need for further perioperative intervention studies focused on shortened fasting times and the use of fast-absorbing carbohydrates to confirm their added benefit to safety, documented as an empty stomach through bedside ultrasound.
